using a GUI, automatically creating and storing information related to wiring between devices in
a predetermined format, designing an acoustic system This includes automatically displaying
information that is important when doing this, automatically creating a device list for the entire
sound system, and automatically creating a rack mount diagram.
Each function will be described in order below.
[0085]
(1) Creation of System System Diagram The first function of the present apparatus is to easily
create a system diagram using a GUI.
10-05-2019
16
[0086]
FIGS. 2 and 3 are flowcharts for explaining the operation of the acoustic system design support
system according to the present embodiment, and in particular, FIG. 2 shows a main algorithm
for creating a system diagram. FIG. 3 shows an output system diagram creation algorithm in FIG.
The flowcharts shown in FIGS. 2 and 3 are stored as a control program in the program area 13 of
the storage unit 9 and executed by the CPU 7.
[0087]
First, in step S1000, the system diagram creation support software is activated by the user who is
the designer, and when the system diagram creation button is clicked, the base paper screen of
the system diagram is displayed on the display 5 .
FIG. 4 is an example of the original paper screen.
[0088]
Then, in step S1100, an output system diagram (system diagram from the mixer to the speaker)
is created based on the input of a simple GUI operation by the user.
The contents of this output system diagram creation algorithm are shown in the flow diagram of
FIG.
[0089]
First, in step S1110, in order to design from the speaker which is the final output stage of the
sound system, the number and type of speakers to be arranged are determined, and
10-05-2019
17
corresponding icons are arranged on the original paper screen.
FIG. 5 is an example of a screen at a stage where the speakers are arranged, and shows a part of
the screen.
Here, the model of the speaker is determined to a preset initial value, but there are the following
two methods for determining the number of speakers.
[0090]
In the first method, the user himself selects an audio device (here, a speaker) through the GUI,
and also determines the number of audio devices.
Specifically, taking FIG. 4 as an example, a user opens a menu screen for selecting a speaker by
clicking the speaker selection button 19 from the tool bar 18 with a mouse on the GUI screen, for
example, and sequentially The necessary speaker is selected from among the above, and the
speaker icon 20 is arranged on the base paper screen.
[0091]
In the second method, the arrangement, model, and number of speakers are determined by
acoustic simulation software.
In this case, by reading the speaker setting data file created by the acoustic simulation software,
the corresponding icons are automatically aligned on the original paper screen.
In this case, the acoustic simulation software may be installed in the present apparatus or may be
installed in an external computer.
In the latter case, the speaker setting data file is downloaded from an external computer.
10-05-2019
18
[0092]
Further, in the vicinity of the arranged icons, as shown in FIG. 5, the model name 21 of the
corresponding speaker and the system name 22 are displayed.
The systematic name 22 can be freely set or changed by the user.
Although one system name 22 is displayed for each system, one model name 21 is displayed for
each arranged device.
As the system name 22, for example, names (for example, a proscenium speaker system, a ceiling
speaker system, a side speaker system, etc.) classified according to the arrangement position of
the speakers are used.
Here, the term “system” refers to a unified connection that is sequentially connected by a
combination of a cable and a related device connected by the cable.
[0093]
Then, in step S1120, the sound equipment of one preceding stage to be arranged next is selected,
and the necessary number of corresponding icons are arranged on the original paper screen.
The selection of the audio device is made based on the user's GUI operation input.
At this time, the output terminals of the arranged front-stage audio device are programmed to be
automatically wired in a one-to-one correspondence with the input terminals of the subsequentstage audio device already arranged.
[0094]
10-05-2019
19
For example, when the front stage of the speaker is an amplifier, when the user selects the
amplifier through the GUI, the device database is searched to acquire the number of input
terminals of the speaker, and the input terminal icons of all speaker icons 20 currently arranged.
After arranging the same number of amplifier icons 23 as the total number of 25 on the left side
of the speaker icon position on the screen, the output terminal icon 26 of each amplifier icon 23
and the input terminal icon 25 of each speaker icon 20 are automatically paired one to one.
Connect in a line.
FIG. 6 is an example of a screen at a stage where the amplifiers are arranged and connected.
[0095]
Of course, when the output terminal of each amplifier and the input terminal of each speaker do
not correspond on a one-to-one basis, for example, in the case of parallel connection such as
connecting a plurality of speakers to one amplifier, Can change the connection by GUI.
[0096]
As a result, it is not necessary for the user to carry out connection work one by one as in the
conventional CAD work, and the burden on the user who is the designer can be alleviated.
[0097]
In the present embodiment, not only in the case of the speakers but also in the stage of arranging
the sound devices on the screen for all the sound devices, the models of the sound devices to be
arranged are for each category such as speakers and amplifiers. It is set to use the initial value of.
If the desired model is different, of course, the user can change the setting of the model for each
audio device on the GUI.
As a method of selecting an initial value, for example, a method of selecting a device registered
first in a device database, a method of selecting a least expensive device, and the like can be
mentioned.
10-05-2019
20
[0098]
Then, in step S1130, the user determines whether the audio device arranged in step S1120 is an
audio device corresponding to the subsequent stage of the mixer output.
[0099]
If, as a result of this determination, the sound device placed immediately before is not the latter
stage of the mixer output, the process returns to step S1120, and the same process is performed
for the sound device one more previous stage.
That is, as described above, when the user selects an audio device in the previous stage, the
number required first for the selected audio device is the number of input terminals of the audio
device arranged in the previous time. Arrange the acoustic devices (model is the initial value) for
the number of input terminals of the previously arranged acoustic device on the screen, and pair
the output terminal of the acoustic device to be arranged this time with the input terminal of the
previously arranged acoustic device Connect automatically with 1.
Subsequently, the user changes the model, the number, and the system as needed through the
GUI.
[0100]
On the other hand, when the sound device disposed immediately before is the latter stage of the
mixer output, the process returns to the flow chart shown in FIG.
[0101]
Thus, the system system diagram (output system diagram) of the output system is created by
repeatedly performing the process of step S1120 up to the latter stage of the mixer output.
[0102]
Note that the layout of the audio equipment disposed on the screen can be changed by the user
through the GUI as needed.

[0103]
Referring back to the flowchart of FIG. 2, in step S1200, an input system diagram (system
diagram from the microphone to the mixer) is created based on the input of a simple GUI
operation by the user.
When creating an input system diagram, it is set from an input device such as a microphone or a
CD player, which is the first stage of input.
While the output system diagram is created from the output side while the input system diagram
is created from the input side in this way, the contents of the input system diagram creation
algorithm are the contents of the output system diagram creation algorithm (see FIG. 3) Since it
is the same, the description is omitted.
[0104]
Then, in step S1300, setting of the mixer is performed based on the created output system
diagram and input system diagram.
Specifically, the number of output channels required for the mixer is determined from the output
system diagram generated in step S1100, and the number of input channels required for the
mixer is determined from the input system diagram generated in step S1200.
Then, based on the obtained number of input / output channels, a feasible mixer is selected from
the device database and arranged on the screen, and the mixer and the mixer input / output side
audio device are automatically connected.
This completes the creation of the system flow diagram.
[0105]
As described above, according to the present apparatus, based on the connection rules given in
advance, a system systematic diagram is created using the GUI. More specifically, the audio
10-05-2019
22
device to be arranged next has an operation input of the GUI When selected, the necessary
number of corresponding icons are automatically arranged on the screen, and one-to-one
connection is made, so that the user can create a system systematic diagram more easily.
[0106]
In this embodiment, when creating the system flow diagram, it is created from the flow diagram
(output flow diagram) on the output side (speaker side), but of course it is not limited to this. It is
also possible to create from a system diagram (input system diagram) on the input side
(microphone or CD player side).
[0107]
Although the operation of the GUI has been described by taking the toolbar and menu operations
as an example, the present invention is not limited to this and can include all so-called GUIs that
can be visually recognized.
[0108]
(2) Creation of connection information The second function of this device is to create and hold
information related to the connection between devices, in other words, information resulting
from the connection between devices in a predetermined format It is a function.
The information related to the connection between devices includes, for example, information on
which audio device is connected to which audio device (hereinafter referred to as “device
connection information”), and the electrical characteristics of the connection body generated by
the connection of devices (for example, For example, there is information (hereinafter referred to
as “connector electrical property information” or “connector electrical property
information”) related to the load impedance and the required applied voltage.
Hereinafter, the case of the device connection information and the case of the connector
electrical characteristic information will be sequentially described.

Case of Device Connection Information FIG. 7 is a flowchart for explaining the device connection
information list creation operation of the audio system design support device according to the
present embodiment.
Here, as shown in FIG. 7, step S1400 and step S1500 are inserted into the flow chart shown in
FIG.
Here, the device connection information list is a list of device connection information, that is, a
list indicating which audio device is connected to which audio device.
The flowchart shown in FIG. 7 is stored as a control program in the program area 13 of the
storage unit 9 and executed by the CPU 7.
[0110]
Steps S1000 to S1300 are the same as the steps of the flow chart shown in FIG.
[0111]
Then, in step S1400, identification numbers are set for individual audio devices (including cables)
arranged on the created system flow diagram.
[0112]
In step S1500, a device connection information list of a predetermined format is created using
the set identification number, and is stored in the database area 17.
FIG. 8 is an example of the device connection information list.
FIG. 9 is an example (only a part) of a system diagram corresponding to the device connection
information list shown in FIG.

For example, an identification number 001 is given to the amplifier A, and one end
(corresponding to an input terminal) of the cable A and the cable B given identification numbers
003 and 004 respectively is connected to the output terminal.
Further, to the input terminal of the amplifier A, acoustic devices (for example, an amplifier, a
filter, and the like) having identification numbers 009, 013, and 018 (not shown) are connected.
The other end (corresponding to the output terminal) of the cable A of the identification number
003 is connected to the speaker A to which the identification number 008 is given, and the other
end (corresponding to the output terminal) of the cable B of the identification number 004 is A
speaker B given the number 012 is connected.
That is, the cable A of the identification number 003 is connected to the input terminal of the
speaker A of the identification number 008, and the cable B of the identification number 004 is
connected to the input terminal of the speaker B of the identification number 012.
[0113]
FIG. 10 is a flow chart showing another algorithm for creating a device connection information
list.
Here, as shown in FIG. 10, step S1112, step S1114, step S1122, and step S1124 are inserted into
the flow chart shown in FIG.
The flow chart shown in FIG. 10 is stored as a control program in the program area 13 of the
storage unit 9 and executed by the CPU 7.
[0114]
Step S1110 is the same as the step shown in the flowchart of FIG.
10-05-2019
25
[0115]
Then, in step S1112, identification numbers are set for the speakers arranged in step S1110.
[0116]
Then, in step S1114, the speaker arranged in step S1110 and the identification number set in
step S1112 are registered in the device connection information list of a predetermined format.
[0117]
Step S1120 is the same as the step in the flowchart shown in FIG. 3, and thus the description
thereof is omitted.
[0118]
Then, in step S1122, identification numbers are set for each of the acoustic devices (including
the cable after automatic connection) arranged in step S1120.
[0119]
Then, in step S1124, each acoustic device (including a cable) disposed in step S1120 and the
identification number set in step S1122 are registered in the above-described device connection
information list, and are set up to the present time. The device connection information (the
output terminal side connection device and the input terminal side connection device in the
example of FIG. 8) is registered within a predetermined range using the identification number.
[0120]
Step S1130 is the same as the step in the flowchart shown in FIG. 3, and thus the description
thereof is omitted.
[0121]
Then, in step S1200 of the flow chart shown in FIG. 2, the same processing as the flow chart
shown in FIG. 10 is performed, and further, after step S1300 in the flow chart shown in FIG. The
same processing as step S1122 and step S1124 is performed.
[0122]
10-05-2019
26
In this case, the timing of registering data in the device connection information list is not limited
to the above example.
For example, step S1114 and step S1124 are deleted from the flow chart shown in FIG. 10, and
in the flow chart shown in FIG. 2, each step of step S1100 to step S1300 is completed, or
collectively after step S1300 is finished. It is also possible to register data in the device
connection information list.
[0123]
As described above, according to the present apparatus, when creating a system diagram,
identification numbers are set for all the audio devices (including cables) on the created system
diagram (FIG. 7). Each time an audio device (including a cable after automatic connection) is
placed on the screen or an identification number is set for the audio device (see FIG. 10), device
connection information is displayed in the form of a list. The device connection information can
be managed by identification numbers for storage and management, which is very useful when
constructing various algorithms described later.
[0124]
When a change occurs in the system systematic diagram, the system systematic diagram after
the change is analyzed, and the identification number of the acoustic device of the changed part
and the identification number of the acoustic device to which the acoustic device is connected
are It is programmed to investigate and automatically rewrite the device connection information
of the corresponding part.
For example, when the user changes the device type or changes the wiring, the connection
information between the corresponding device or wiring and the devices connected to the left
and right (input / output terminal side) is processed according to the process in step S1500 of
FIG. It is programmed to update sequentially.

27
In the case of connector electrical property information FIG. 11 is a flow chart showing an
algorithm for obtaining the electrical property information of the connector.
The flowchart shown in FIG. 11 is stored as a control program in the program area 13 of the
storage unit 9 and executed by the CPU 7.
[0126]
First, in step S2000, the necessary device connection information is read from the device
connection information list (see FIG. 8) for audio devices connected to other audio devices.
[0127]
Then, in step S2100, the specific electrical characteristics of the necessary audio equipment are
read from the equipment database, and the read data is stored in the form of adding an item to
the equipment connection information list.
FIG. 12 is an example of the device connection information list to which impedance information
is added as an item.
[0128]
Then, in step S2200, on the basis of the device connection information read in step S2000 and
the electric characteristics unique to the device read in step S2100, the electric characteristic
information of the desired connector is calculated according to a predetermined calculation
formula (theoretical operation). Calculate theoretically.
[0129]
Then, in step S2300, the electrical characteristic information of the connector, which is the
calculation result, is stored in a predetermined format, for example, as a new item added to the
device connection information list.
[0130]
As described above, the electrical characteristic information of the connection body (for example,
10-05-2019
28
the information of the load impedance connected to the output side of the device, etc.) resulting
from the connection of the devices utilizes the device connection information and the device
database. You can easily ask for it.
[0131]
Here, as an example, a method of calculating and managing the output impedance of the
connected audio device for each connection will be described with reference to the flowchart
shown in FIG.
[0132]
For example, in the case of the acoustic system shown in FIG. 13, as a result of reading the device
connection information, two speakers A and B of identification number 008 and identification
number 012 are connected in parallel at the output terminal of amplifier A of identification
number 001. If the input impedances of the two speakers A and B are respectively 8.0 Ω and
16.0 Ω as a result of reading of the device-specific electrical characteristics from the device
database (step S2000) (step S2000) S2100 (refer to FIG. 12) and theoretical operation, the load
impedance connected to the output side of the amplifier A with identification number 001 is a
combined load impedance when 8.0 Ω and 16.0 Ω are connected in parallel according to Ohm's
law. (Hereinafter, the expression “load impedance of parallel body” is also used) is calculated
as 5.3 Ω (step S2200).
The calculated value is registered as a new item of the device connection information list related
to the amplifier A (step S2300).
[0133]
At this time, if, for example, the calculation result is displayed on the screen when the user
double-clicks the corresponding icon on the system diagram after creation or creation, for
example, it is very useful for the design of the acoustic system. It is.
[0134]
Further, the load of the amplifier A can be calculated by retaining information of voltage, current,
and power in the same format in addition to the information of impedance.
10-05-2019
29
[0135]
For example, when the required power required for each speaker is obtained by the sound
simulation software, it is considered to hold the information in a format as shown in FIG.
[0136]
At this time, from the impedance information shown in FIG. 12 and the required power
information shown in FIG. 14, the value of the applied voltage required for each of the speakers
A and B to the amplifier A can be obtained.
In this example, the required applied voltage value of the speaker A having the identification
number 008 is 32.25 V from the positive square root of 130 W × 8.0 Ω because the load
impedance is 8.0 Ω with respect to the required power 130 W. The required applied voltage
value of the speaker 012 is 30.98 V from the positive square root of 60 W × 16.0 Ω because
the load impedance is 16.0 Ω with respect to the required power of 60 W.
[0137]
However, in the case of parallel connection, the voltage value applied to the input terminal of the
speaker is actually the same for the identification number 008 and the identification number
012.
Therefore, in order to make the calculation possible, the algorithm in advance "adjust to one of
the higher one of the required applied voltage (that is, the larger one of the required power) and
the lower one (that is, the smaller one of the required power)" Decide on.
If such a promise thing is decided beforehand, correspondence with real wiring will also be easy
to take.
In this example, assuming that the required applied voltage is higher, the required applied
voltage value is 32.25 V, and this value and the value 5 of the load impedance of the parallel
body of the speaker A and the speaker B obtained from the impedance information From .3 Ω,
the output power of the amplifier A is calculated to be 196.24 W by 32.25 V × 32.25 V ÷ 5.3
10-05-2019
30
Ω.
[0138]
Similarly to the above, if this calculated value is displayed on the screen when the user doubleclicks the corresponding icon on the system systematic diagram, it is very useful for the design of
the acoustic system.
[0139]
As described above, in order to simplify the description, although the description has been made
with the cable omitted, the same applies, of course, to the case where the cable is considered.
[0140]
For example, as shown in FIG. 9, it is assumed that the device connection information including
the cable is held.
Here, it is assumed that the impedances of the cables A and B in the same figure are both 1 Ω,
and this data is also held.
At this time, it is determined in advance that the input / output impedance of the cable is
determined by adding the impedance of the cable itself to the impedance of the acoustic device
connected to the cable.
Further, for example, as for the list shown in FIG. 12, the information on the electrical
characteristics may be expanded to hold data as shown in FIG.
The list shown in FIG. 15 is an example of the system flow diagram shown in FIG.
Here, refer to FIG. 16 for “self input impedance”, “self output impedance”, “input side
impedance”, and “output side impedance” in FIG. 15.
10-05-2019
31
These terms are all expressions for the central device A.
[0141]
Next, an algorithm for creating the list shown in FIG. 15 will be described according to the flow
chart shown in FIG.
[0142]
First, necessary device connection information is read from the device connection information
list (step S2000).
[0143]
Then, the device database is searched to read the self input / output impedance of the necessary
audio device (step S2100).
Since both the self input impedance and the self output impedance are electrical characteristics
unique to each device, they can be read from the device database.
However, for cables, the following three steps are required.
[0144]
First, in the first step, the impedance of the cable itself is read from the device database.
[0145]
Next, in the second step, with respect to the input impedance, the self-input impedance of the
device connected to the output side is added.
For example, in the case of the cable A of the identification number 003, the input impedance
8Ω of the speaker A of the identification number 008 connected to the output side is added to
the cable impedance 1Ω to obtain 9Ω.
10-05-2019
32
[0146]
Finally, in the third step, the output impedance is added to the self-output impedance of the
device connected to the input side.
For example, in the case of the cable A of the identification number 003, the output impedance
0.01 Ω of the amplifier A of the identification number 001 connected to the input side is added
to the cable impedance 1 Ω to obtain 1.01 Ω.
[0147]
Then, based on the read information (however, in the case of a cable, the calculation result based
on the read information), the input side impedance and the output side impedance are calculated
(step S2200).
For example, the output impedance of the amplifier A of identification number 001 is 5.9 Ω by
performing parallel impedance calculation of the self-input impedance of the cable A of
identification number 003 and the cable B of identification number 004 connected to the output
side. Is calculated.
Further, as the input impedance of the cable B with the identification number 004 is only one
amplifier A connected to the input side with the amplifier A with the identification number 001,
its own output impedance 0.01Ω is registered as it is.
[0148]
If the above processing procedure is carried out for all the devices, the electrical characteristic
information of the connector as shown in the list of FIG. 15 can be obtained.
[0149]
As described above, according to the present apparatus, since the electrical characteristic
information of the connection body is obtained and stored in the form of a list, it becomes
10-05-2019
33
possible to freely refer to other applications, and display of design information to be described
later Becomes possible.
[0150]
Here, although the impedance is described as the electrical property information of the
connection body, it is of course not limited to this, and a list may be constructed based on the
same idea for voltage, current, power, etc. Can.
[0151]
Further, in the case of a cable, since the impedance changes according to the length thereof, it is
possible to carry out the calculation in consideration of the length information.
[0152]
(3) Display of design information The third function of this device is to automatically display
information (design information) that is important when designing an acoustic system and to
support the user's design. It is.
This is effective, for example, in the process of creating the system diagram or in the completion
stage of the creation.
[0153]
Here, the information that is important when designing an audio system includes, for example,
information that requires a warning to the user, such as overload information of equipment, and
correspondence information between the system system and the speaker arrangement. .
The following will be described in order.
[0154]
10-05-2019

【0154】a.
Required Warning Information to User FIG. 17 is a flowchart for explaining the required warning
information display operation of the audio system design support device according to the present
embodiment.
Here, it is assumed that the present apparatus already holds the above-mentioned device
connection information and connection body electrical characteristic information.
The flowchart shown in FIG. 17 is stored as a control program in the program area 13 of the
storage unit 9 and executed by the CPU 7.
[0155]
First, in step S3000, necessary device connection information is read from the device connection
information list (see FIG. 8).
[0156]
In step S3100, necessary connector electrical property information is read from the electrical
property information list (see FIG. 15).
[0157]
Then, in step S3200, the device-specific electrical characteristics (eg, the allowable value of the
electrical load, etc.) used in the determination are read from the device database.
[0158]
Then, in step S3300, based on the data read in steps S30000 to S3200, it is determined whether
or not it is necessary to present information to the user for the corresponding device.
[0159]
Then, in step S3400, the determination result of step S3300 is confirmed.
10-05-2019
35
As a result, if information presentation to the user is necessary, the process proceeds to step
S3500, and if information presentation to the user is not necessary, the process immediately
ends.
[0160]
In step S3500, the information obtained in step S3300 is presented to the user by a
predetermined method, for example, by highlighting the icon of the corresponding device.
Here, highlighting means displaying in distinction from other icons by reverse display, blinking
display, or the like.
[0161]
As described above, the algorithm shown in FIG. 17 is performed by utilizing the data (device
connection information and connector electrical property information) obtained by the abovedescribed function and the device database.
[0162]
Here, as one example, the case of displaying the overload information of the device will be
described with reference to FIG.
[0163]
For example, in the case of the acoustic system shown in FIG. 13, the device connection
information of the amplifier A with the identification number 001 is obtained from the device
connection information list, and the value 196 of the required output power for the amplifier A is
obtained from the connected object electrical characteristics information list. Each 24 W is read
(step S3000, step S3100).
On the other hand, the limit value (for example, 100 W) of the output power of the amplifier A is
read from the device database (step S3200).
10-05-2019
36
Then, the two values are compared to determine whether the amplifier A is in an overload state
(step S3300).
At this time, if the required output power is larger than the limit value, it is determined that the
amplifier is in an overload state.
In this example, since the required output power (196.24 W)> the limit value (100 W), it is
determined that the amplifier A is in an overload state (an alarm condition).
Therefore, when it is determined that the load is overloaded (step S3400: YES), for example, as
shown in FIG. 18, highlight the corresponding icon (corresponding to the amplifier A) of the
system flow diagram created or under creation by the user. To notify the user of that (step
S3500).
As a result, when the device is overloaded, the user can be warned, and design support can be
performed.
[0164]
Similarly, when the determination is made on the impedance, it can be coped with by making the
load impedance calculated by the algorithm shown in FIG. 11 and the range of the allowable load
impedance value of the device into a database.
[0165]
For example, in the case of the acoustic system also shown in FIG. 13, assuming that the
calculated load impedance is 5.3 Ω and the allowable load impedance range of the
corresponding device registered in the device database is 6 Ω to 20 Ω. As a result of the
comparison of the values of, it is possible to warn the user as well because the load impedance is
out of tolerance.
[0166]
【0166】b.

Correspondence information between the system system and the speaker arrangement In
general, what is important in creating the system system is, for example, a signal system and
which speaker is affected by operating an equalizer or a delay of a certain system. The design is
to always keep in mind the correspondence with the spatial position of the speaker.
Here, a method of supporting the design of the acoustic system by visualizing and displaying the
correspondence relation to the designer will be described.
[0167]
For example, in the existing acoustic simulation, a three-dimensional CAD model of the space in
which the speaker is to be installed is constructed, the speaker is virtually installed on the CAD
model, and the sound reflecting the characteristic data of the speaker An analysis is being done.
At this time, for example, as shown in FIG. 19, the relationship between the installation position
of the speaker and the installation space can be confirmed by the designer by displaying the
room model 30 and the icon 31 indicating the speaker on the screen. ing.
FIG. 19 shows an example in the case of arranging a speaker in a baseball stadium, and the arrow
indicates the direction of the speaker.
[0168]
Here, in the present embodiment, as shown in FIG. 20, a system system diagram 40 under
creation and a speaker layout diagram 41 as shown in FIG. 19 are displayed in parallel on the
screen.
Then, as shown in FIG. 21, when the designer selects the wiring or device input / output terminal
of the system system diagram 40 in the process of creating or completing the creation using the
GUI, the system system diagram 40 Extract all connected devices and wires, highlight
corresponding icons (eg, speaker icon 42 and amplifier icon 43), and highlight corresponding
10-05-2019
38
speaker icon 42 in speaker layout 41 Turn
Thereby, the designer can easily confirm the configuration of the system system and the
positional relationship of the speakers.
In addition, since a plurality of amplifiers are connected to the mixer or processor, the icon 25 of
the mixer or processor is not highlighted (see FIG. 21).
[0169]
FIG. 22 is a flow chart showing an algorithm for realizing this.
Here, it is assumed that the present apparatus already holds the above-described device
connection information.
The flowchart shown in FIG. 22 is stored as a control program in the program area 13 of the
storage unit 9 and executed by the CPU 7.
[0170]
First, in step S4000, the user selects the wiring or the input / output terminal of the device on
the system system diagram 40 during or after the creation by the GUI operation.
[0171]
[0171] Then, in step S4100, based on the device connection information, a device and a wire
connected to the wire or input / output terminal selected in step S4000 are searched.
[0172]
In step S4200, all the corresponding devices and wires are listed up based on the search result in
step S4100.
[0173]
10-05-2019
39
Then, in step S4300, all the equipment and wiring icons listed in step S4200 (for example,
speaker icon 42 and amplifier icon 43) are highlighted in system block diagram 40 (see FIG. 21).
).
[0174]
At this time, in the speaker layout diagram 41, identification numbers similar to those of the
speaker icon 20 on the system system diagram 40 are assigned to the speaker icons 31 arranged
in the speaker layout diagram 41, At step S4200, when the highlighting instruction is issued
(step S4300), the icon 42 of the speaker of the corresponding identification number is
highlighted as in the case of the system flow chart 40 (step S4200). Do.
[0175]
Further, as a development example, further linking with the acoustic simulation to reflect the
signal level of the system on the simulation result as needed can provide useful information for
the designer.
[0176]
For example, the existing acoustic simulation has a function of calculating the sound pressure
level distribution in the passenger seat according to the applied power of each speaker.
FIG. 23 is an example of the calculation result of sound pressure level distribution.
[0177]
Therefore, here, the function is taken into the software of this apparatus so that the calculation
result is drawn and displayed in the speaker layout diagram 41 shown in FIG.
As described above, since the present device holds the required power of the speaker or the
output power of the amplifier as data, if the power value is input to the calculation unit of the
acoustic simulation and recalculated, the desired simulation result is obtained. You can get
10-05-2019
40
FIG. 24 is an example of simulation calculation and screen display obtained in this manner.
In this example, the sound pressure level distribution in the field is calculated and displayed.
Here, on the screen, dark parts represent parts where the sound pressure level is high, and light
parts represent parts where the sound pressure level is low.
[0178]
Further, as another development, when the designer changes the device state value such as
volume on the GUI screen, the simulation such as the sound pressure level distribution is
recalculated and the result is displayed accordingly. If done, the designer can design while
predicting the on-site adjustment and the characteristics of the sound field, which is very
effective.
[0179]
FIG. 25 is a flow chart showing an algorithm for realizing this.
The flow chart shown in FIG. 25 is stored as a control program in the program area 13 of the
storage unit 9 and executed by the CPU 7.
[0180]
First, in step S5000, the user corrects and changes the device state value on the GUI screen.
[0181]
Specifically, for example, in the system system diagram 40 shown in FIG. 24, when the user
double-clicks a desired device icon, an application (software) is constructed in advance so that
the setting screen of the device pops up. deep.
An example of this is as shown in FIG.
10-05-2019
41
FIG. 26 shows a state in which the user double-clicks the amplifier and the amplifier setting
window 44 pops up.
After that, the device state value is adjusted and changed by the GUI.
For example, suppose that the attenuation level of the amplifier is currently 0 dB, and this is
changed to -3 dB (see FIG. 26).
At this time, the change is reflected in the connector electrical property information of each
device described above.
For example, when the output power of the corresponding amplifier is 300 W, the variation of -3
dB is reflected on this.
In actual calculation, the output power is 150 W when the change of -3 dB is reflected.
Then, using this data, the connector electrical property information of the corresponding device
is updated.
[0182]
Then, in step S5100, reflection and update on connected connected devices are performed.
That is, after the change is made in step S5000, the device connection information is searched to
reflect the change for the connected device.
This is done by re-executing the previously described algorithm (such as FIG. 11).
10-05-2019
42
[0183]
Then, in step S5200, data is reflected on the acoustic simulation program.
That is, after the connector electrical property information of all related devices is updated, the
applied power value of the speaker is reflected on the acoustic simulation program.
For example, if the speaker applied power before the change is 150 W, 75 W should be updated
as data due to a -3 dB amplification change.
Therefore, this value is passed to the acoustic simulation program to cause recalculation.
[0184]
Then, in step S5300, after recalculation, the result is drawn on the acoustic simulation result
screen of FIG.
[0185]
As described above, according to the present apparatus, information (design information) that is
important when designing an acoustic system, for example, warning information required for a
user such as overload information of a device, a system system, etc. Since the correspondence
information with the speaker arrangement can be automatically displayed, the user can simply
and effectively perform a check during the creation of the system flow diagram or at the
completion stage of the creation.
[0186]
(4) Creation of Device List The fourth function of the present apparatus is to automatically create
a list (device list) of audio devices used in the entire audio system.
Listing the number of devices in the entire system is very useful in consideration of system cost
and the like.
10-05-2019
43
[0187]
Here, a device list representing the number of devices in the entire system and the like is
automatically created from the system flow diagram.
The method of automatically creating the device list from the system flow diagram is as follows.
[0188]
As described above, when creating a system flow diagram, identification numbers are assigned to
each device and device connection information is managed in a list format. Here, model
identification is performed for each model (part number). A number is assigned to create a
database, and the amount of information of device connection information is further expanded to
include and manage a model identification number.
[0189]
For example, in the case of the system flow diagram shown in FIG. 27, the model of the speaker
with the identification number 001 is the speaker b, the model of the speaker with the
identification number 002 is the speaker c, and the model of the amplifier with the identification
number 003 is the amplifier a.
Here, the database for each model is managed, for example, in the format shown in FIG.
Specifically, for example, 002, 003, and 011 are assigned to the speaker b, the speaker c, and the
amplifier a, respectively, as model identification numbers.
At this time, for the connection relationship shown in FIG. 27, model information is managed, for
example, in the format shown in FIG.
Specifically, a speaker with the model identification number 002 (speaker b) is assigned to the
speaker with the identification number 001, a speaker with the model identification number 003
10-05-2019
44
(speaker c) is assigned to the speaker with the identification number 002, and the identification
number 003 An amplifier (amplifier a) of model identification number 011 is assigned to the
amplifier of.
That is, model information is managed in a form in which an identification number and a model
identification number are paired.
[0190]
Therefore, by comparing the information shown in FIG. 29 with the database shown in FIG. 28, it
is possible to create a device list as shown in FIG. 30, for example.
In the example of FIG. 30, the unit price of each model is read from the device database, and the
unit price and subtotal of each device (and the total price of all models) are included in the device
list.
[0191]
If a plurality of identical models are arranged, a loop search is performed for the model
identification numbers in the list shown in FIG. 29 when the apparatus list (see FIG. 30) is
created, and the identical model identification numbers are confirmed. In this case, an algorithm
may be constructed to increase the number by one.
[0192]
As described above, according to the present apparatus, since the device list can be automatically
created, the user can easily study the system cost and the like.
[0193]
(5) Design of rack mounting The fifth function of the present apparatus is a function of
automatically creating a rack mounting diagram to support the design of installation (rack
mounting) of equipment.
10-05-2019
45
Generally, in acoustic system design, not only creation of a system diagram, but rack mounting is
also an important design factor.
In particular, since the rack mount design involves heat dissipation and power capacity of the
device, it is extremely useful to manage such information by software and present it to a designer
(user) as design support.
[0194]
Here, rack mounting is designed using the above-described device list.
[0195]
FIG. 31 is a flow chart showing an algorithm for performing rack mount design support.
Here, the device list as shown in FIG. 30 is sorted by model category, and a list indicating
whether or not it is a rack mount target and the required height is created and stored.
FIG. 32 is an example of such a list.
Automatic reference is possible by registering in the device database beforehand whether or not
it is the target of rack mounting.
The flow chart shown in FIG. 31 is stored as a control program in the program area 13 of the
storage unit 9 and executed by the CPU 7.
First, in step S6000, the target devices are mounted on the rack in order based on the list shown
in FIG.
At that time, the height (number of U) of the target device is counted.
10-05-2019
46
[0196]
Then, in step S6100, the number of continuously mounted devices is counted to check the
number of continuously mounted devices.
[0197]
Then, in step S6200, it is determined whether the number of continuous loadings checked in step
S6100 exceeds the allowable number of continuous loadings registered in the device database.
As a result of this determination, if the number of continuous mountings does not exceed the
allowable number of continuous mountings, that is, if it is still within the continuous mounting
allowable range, the process immediately proceeds to step S6400 and the number of continuous
mountings exceeds the allowable continuous mounting number In the case, that is, when it is not
within the continuous mounting tolerance, the process proceeds to step S6300.
[0198]
In step S6300, since the number of continuous mountings exceeds the allowable number of
continuous mountings, a blank of 1U is automatically inserted, and the flow proceeds to step
S6400.
[0199]
In step S6400, it is determined whether the rack loading limit has been exceeded.
Specifically, for example, whether the total height (total number of Us) of the equipment and
blanks mounted in the rack exceeds the number of racks that can be mounted, or the total power
and total heat generation in the rack are permitted. It is determined whether it has exceeded.
[0200]
Then, in step S6500, the determination result of step S6400 is confirmed.
10-05-2019
47
As a result, if the rack mounting limit is exceeded, that is, the total height (total U number) of the
equipment and blanks mounted in the rack exceeds the mountable number of racks, or the total
power and total power in the rack If the calorific value or the like exceeds the allowable value,
the process proceeds to step S6600, and if neither of them is hit and the loading limit of the rank
is not exceeded, the process returns to step S6000.
[0201]
In step S6600, since the rack installation limit has been exceeded, the next rack is selected or,
after adding a rack, the process returns to step S6000 to mount the next target device in the next
rack or expansion rack. .
[0202]
For example, rack mount calculation is performed according to the algorithm shown in FIG. 31,
and model icons (height of each model and height of icon are displayed on the screen in step
S6000, step S6300 and step S6600 of the algorithm shown in FIG. Arrange the corresponding).
As a result, for example, with reference to FIG. 50 for rack mounting with respect to the list
shown in FIG. 32, if the height (loading limit) of one rack is 9 U and the number of continuous
loading possible is two, it becomes as shown in FIG. The example shown in FIG. 33 shows the
case where four racks indicated by reference numerals “51” to “54” are arranged, and for
example, in the rack 1 indicated by reference numeral “51”, the amplifier at the bottom stage
is The amplifier a-3 is mounted on the stage immediately above the a-4. Since the number of
racks that can be continuously mounted is two, when the amplifier a-4 and the amplifier a-3 are
successively mounted, a blank (space) is inserted before the third unit is mounted. The height of
the blank is 1U. On the blank, two amplifiers, an amplifier a-2 and an amplifier a-1, are mounted
in series. In this state, since the rank 1 has reached the mounting limit 9U, the mounting on the
rack 1 is completed.
[0203]
When the arrangement of the rack mount drawing 50 automatically created in this manner is
changed in consideration of usability and the like, the equipment may be replaced or moved by
the GUI operation. Also, in some cases, a user (designer) may instruct to add a rack. FIG. 34
10-05-2019
48
shows an example of the GUI operation. FIG. 34 shows a situation where a device icon storage
area 55 is provided in addition to the rack mount diagram 50, the device icon is temporarily
stored, and the rack mount is edited by the GUI. Specifically, for example, when it is desired to
replace the amplifier c-1 and the amplifier c-2 mounted on the rack 3 indicated by the code "53",
the user drags and drops the mouse with the amplifier c-1 and the amplifier c-1. c-2 can be
replaced. Also, the user can move the icon of the amplifier b-2 mounted on the rack 2 indicated
by reference numeral 52, for example, to the device icon storage area 55 by drag and drop with
the mouse.
[0204]
Furthermore, when performing such editing and design work, it is very useful to present design
information to a designer with a GUI in the form as shown in FIG. 35, for example. Here, the
items in the list shown in FIG. 35 are total power consumption, total calorific value, and total
weight in each rack. These calculation results can be easily obtained by searching the device
database for power consumption, calorific value, and weight of each device alone, and summing
up for each rack.
[0205]
As described above, according to the present apparatus, since the rack mount diagram 50 can be
automatically created while confirming the rack mounting limit or mounting condition, the user
can easily design the rack mount. It can be carried out.
[0206]
As described above, according to the present invention, in designing an acoustic system, the
design efficiency can be further improved to further reduce the burden on the designer.
