However, the group number of the group “rack” is extracted from the group number, and the extracted group number indicates to which rack the amplifier belongs. Also, information on “device ID”, “device name”, “area ID”, “area name”, and “device information” is extracted from the device information of “ACD” in the device information. This device information is device information of “old AMP1 (old amplifier 7a)” and “old AMP2 (old amplifier 7b)”, and devices of “old AMP1 (old amplifier 7a)” and “old AMP2 (old amplifier 7b)”. Information on “device ID”, “device name”, and “group number” is extracted from the information. However, as for the group number, the group number of the group “rack” is taken out, and the rack to which the amplifier belongs can be known from the taken out group number.

  Next, a rack tree is created in step S11. In this step, the area ID is referred to from the information extracted in step S10, the amplifier groups belonging to the same area having the same area ID are grouped, and the group number of each amplifier belonging to each area is referred to. First, group the amplifiers for each group in the first hierarchy, and further group the amplifiers in the group in the next hierarchy up to the rack group in the final hierarchy, and arrange the amplifiers belonging to each rack in the order of device names. To create a rack tree. In step S12, the rack tree created on the display unit 13 is displayed, and the rack tree display process ends. When displaying the rack tree, the extracted “group number” is converted into a group name corresponding to the group number read from the project file, and the group name of each layer is displayed.

FIG. 9 shows a display example of the rack tree displayed on the display unit 13 by performing the rack tree display process.
As shown in FIG. 9, the monitoring screen 40 includes a display unit of a tree display unit 42 and a status display unit 43, and a plurality of tabs 41 for selecting a tree type to be displayed on the tree display unit 42. In FIG. 9, the “Rack” tab 41 is selected as the tree type, the rack tree display process described above is executed, and the rack tree is displayed in the tree display unit 42. In the tree display section 42, amplifier groups belonging to the area having the area name “Area-1” are displayed in a tree form, and the group names of the two groups in the first hierarchy in the tree display are “001 FOH” and “Monitor”. ing. Further, the group names of the three groups in the second hierarchy in which the group “001 FOH” is expanded are “Stage L”, “Stage R”, and “Operator”. Here, “FOH” is an abbreviation of Front Of House and means an operator room located in front of the stage, etc., and “Stage L” and “Stage R” mean the left and right of the stage. It can be seen that the group is a group according to the arrangement of the amplifiers.

  Furthermore, the group names of the two groups in the third hierarchy in which the group “Stage L” is expanded are “001 Rack # 1” and “002 Rack # 2”. Then, the group “001 Rack # 1” is expanded, and it is displayed that two amplifiers “001: 001 Tx6n” and “001: 002 Tx6n” belong to the group “001 Rack # 1”. That is, “001 Rack # 1” and “002 Rack # 2” are rack names, and two amplifiers “001: 001 Tx6n” and “001: 002 Tx6n” are stacked in the rack “001 Rack # 1”. I understand that. The head “001” in “001: 001 Tx6n” is the device ID of the amplifier, and “001 Tx6n” is the device name. In the rack tree display, display for each channel of the amplifier is not performed. In this way, in the rack tree display, each amplifier can be displayed as a group for each rack arrangement, so that it is easy to achieve the purpose by following the lower hierarchy group from the higher hierarchy group. You can find the amplifier to be monitored. When the found amplifier is selected (displayed in white) as shown in FIG. 9, the status display section 43 displays the status display of the selected “001: 001 Tx6n” amplifier. Items displayed on the status display unit 43 include the power switch, input level and output level of the selected amplifier, the temperature of the heat sink, and the like. By monitoring these items, the operational state of the amplifier can be confirmed. When the amplifier has a plurality of channels, an average value, a maximum value, or a minimum value is displayed in the displayed items. In the rack tree display shown in FIG. 9, when a symbol “+” in “□” is clicked on, the tree is expanded and displayed in a lower hierarchy.

  Here, a specific example of the group number will be described with reference to the rack tree display shown in FIG. 9. The group number of the group “001 FOH” in the first hierarchy in the tree display is, for example, “1” and the group “Monitor”. The number is “2”. Then, the group number “Stage L” of the second layer in which the group “001 FOH” is expanded is “1-1”, the group number “Stage R” is “1-2”, and the group “Operator” is the group number. The number is “1-3”. Further, the group number of the third layer group “001 Rack # 1” in which the group “Stage L” is expanded is “1-1-1”, and the group number of the group “002 Rack # 2” is “1-1-2”. " When displayed on the tree display unit 42, each group number is converted into the group name and displayed with reference to a list of group names in the project file.

  By the way, not only in the rack tree display but when any of the amplifiers displayed in the tree display section 42 of the monitoring screen 40 is selected, the status display of the selected amplifier is displayed in the status display section 43 as described above. Become so. In this case, the PC 1 requests state information from the selected amplifier, acquires state information from the amplifier, and displays it on the state display unit 43. FIG. 10 shows a flowchart of status information display processing executed by the PC 1 when this processing is performed. FIG. 11 shows a flowchart of a state information transmission process executed by the selected new amplifier when the selected amplifier is the new amplifier 6a or the new amplifier 6b. The selected amplifier is the old amplifier 7a or the old amplifier. FIG. 12 shows a flowchart of the state information transmission process executed by the ACD 5 in the case of 7b.

First, the status information transmission process shown in FIG. 11 will be described. This status information transmission process is performed when the PC 1 requests the new amplifier 6a or the new amplifier 6b to receive the status information. It is activated by the amplifier 6b. When activated, the state information recorded in the own device is transmitted to the PC 1 in step S30, and the state information transmission process ends.
The state information transmission process shown in FIG. 12 is started by the ACD 5 when the PC 1 requests state information from the old amplifier 7a or the old amplifier 7b. When activated, the state information recorded from the old amplifier 7a or the old amplifier 7b requested in step S40 is acquired. Next, the requested amplifier status information acquired in step S41 is transmitted to the PC 1, and the status information transmission processing ends.

The status information display process shown in FIG. 10 is activated when any of the amplifiers displayed in the tree display section 42 of the monitoring screen 40 is selected, and the status information is displayed in the amplifier selected in step S20. Request transmission. Thus, the above-described state information transmission process shown in FIG. 11 or FIG. 12 is executed, and the PC 1 receives the state information of the selected amplifier. Next, the received state information is displayed on the state display unit 43 of the monitoring screen 40, and the state information display process is terminated.
Items displayed on the status display 43 include the power switch, input level and output level of the selected amplifier, the temperature of the heat sink, etc., limiter operation due to excessive input, operation of the output protection circuit, and output load (connected to the amplifier) It is also possible to display the item of the impedance value of the speaker. The operational state of the amplifier can be confirmed by monitoring these items. In the status display section 43, the power switch can be turned on / off, the attenuator can be set, and the mute can be turned on / off.

Next, a flowchart of the feed structure tree display process executed by the PC 1 is shown in FIG.
The feed structure tree display processing is performed when the “FeedSt.” Tab 41 is selected on the monitoring screen 40 displayed on the display unit 13 of the PC 1 and the tree display is performed with the group “feedst” in view of the role of the amplifier. In step S50, data for displaying the feed structure tree is read from the project file. That is, information of “device ID” or “group number” is extracted from the device information of “new AMP1 (new amplifier 6a)” and “new AMP2 (new amplifier 6b)” in the device information in the project file. However, as for the group number, the group number of the group “feedst” is extracted for each channel, and it is understood from the extracted group number which speaker is connected to the amplifier. Also, information of “device ID” or “device information” is extracted from the device information of “ACD” in the device information. This device information is device information of “old AMP1 (old amplifier 7a)” and “old AMP2 (old amplifier 7b)”, and devices of “old AMP1 (old amplifier 7a)” and “old AMP2 (old amplifier 7b)”. Information on “device ID” or “group number” is extracted from the information. However, as for the group number, the group number of the group “feedst” is extracted for each channel, and it is understood from the extracted group number which speaker is connected to the amplifier.

  Next, a feed structure tree is created in step S51. In this step, the area ID is referred to from the information extracted in step S50, the amplifier groups belonging to the same area having the same area ID are grouped, and the group number of each amplifier belonging to each area is referred to. The amplifiers are grouped into amplifier groups for each group of the first hierarchy, and further grouped into the amplifier groups of the next hierarchy group until the final hierarchy, and the amplifiers belonging to each final hierarchy are arranged in order of device name and channel number. Thus, a feed structure tree in which the channel of the amplifier corresponding to each speaker is displayed is created. In step S52, the feed structure tree created on the display unit 13 is displayed, and the feed structure tree display process ends. When displaying the feed structure tree, the extracted “group number” is converted into a group name corresponding to the group number read from the project file, and the group of each layer is displayed.

Next, FIG. 14 shows a display example of the feed structure tree displayed on the display unit 13 by performing the feed structure tree display process.
In the monitoring screen 40 shown in FIG. 14, the “FeedSt.” Tab 41 is selected as the tree type, the feed structure tree display process described above is executed, and the feed structure tree is displayed in the tree display unit 42. In the tree display section 42, amplifier groups belonging to the area of the area name “Area-1” are displayed as a tree, and the group names of the three groups in the first hierarchy in the tree display are “001 FOH Left” “002 FOH Right”. And “003 Delay Left”. The group names of the three groups in the second hierarchy in which the group “001 FOH Left” is expanded are “001 High” for tweeter, “001 Mid” for squawker, and “001 Low” for woofer. Thus, it can be seen that the group is a group according to the role of the amplifier.

  Furthermore, the group names of the two groups in the third hierarchy in which the group “001 High” is expanded are “001: 1/2” and “002: 3/4”. Then, the group “001: 1/2” is expanded, and it is displayed that two channels “001: 001 Tx6n CH1” and “001: 002 Tx6n CH2” belong to the group “001: 1/2”. . That is, “001: 1/2” and “002: 3/4” are group names each having two channels, and the channel “001: 001 Tx6n CH1” of the amplifier “001: 1/2” is a high speaker (tweeter). ) And the channel “001: 002 Tx6n CH2” is also connected to the high speaker (tweeter). The first “001” in “001: 001 Tx6n CH1” is the device ID of the amplifier, “001 Tx6n” is the device name, and “CH1” is the channel number.

Thus, in the feed structure tree display, a tree display for each channel corresponding to the speaker is performed. Since the amplifier can be displayed on the channel corresponding to the speaker in the feed structure tree display, it is possible to easily find the target monitored amplifier by following the lower hierarchy group from the upper hierarchy group. Can do. When the found amplifier is selected as shown in FIG. 14 (displayed in white), the status display of the selected channel “001: 001 Tx6n CH1” is displayed on the status display unit 43. Items displayed on the status display section 43 include the power switch, input level and output level, heat sink temperature, and the like of the channel of the selected amplifier. By monitoring these items, the operational state of each channel of the amplifier can be confirmed. Further, in the feed structure tree display shown in FIG. 14, when a symbol “+” in “□” is clicked on, a tree is displayed in a hierarchy below it.
In the rack tree display shown in FIG. 9 and the feed structure tree display shown in FIG. 14, a double rectangular icon is displayed in front of the group name of each hierarchy group. Different display colors may be used for each layer so that it can be easily understood which layer the group belongs to. In the rack tree display and the feed structure tree display, the ACD 5 is not displayed, so that the display can be easily viewed.

  As described above, in the PC 1 that is a remote monitoring device according to the present invention, a rack tree display in view of the arrangement (rack) of the amplifier and a feed structure tree display in view of the role of the amplifier are prepared. The tree selected by the user is displayed. For this reason, an optimal tree display according to the purpose of use can be performed, and an amplifier to be monitored can be easily found from the displayed tree. Therefore, it is possible to easily select an amplifier to be monitored, and it is not necessary to monitor the amplifier. In this case, the arrangement of the amplifiers can be easily confirmed by the rack tree display from the viewpoint of the rack in which the amplifiers are stacked. For example, the arrangement of the amplifier in which the problem has occurred can be easily found. In addition, the feed structure tree display makes it possible to easily find and monitor the amplifier to which the desired speaker is connected and its channel.

Next, a flowchart of device tree display processing executed by the PC 1 is shown in FIG.

Read out. That is, information of “device ID” or “area name” is extracted from the device information of “new AMP1 (new amplifier 6a)” and “new AMP2 (new amplifier 6b)” in the device information in the project file. Also, information of “device ID” or “device information” is extracted from the device information of “ACD” in the device information. This device information is device information of “old AMP1 (old amplifier 7a)” and “old AMP2 (old amplifier 7b)”, and devices of “old AMP1 (old amplifier 7a)” and “old AMP2 (old amplifier 7b)”. Information of “device ID” or “device name” is extracted from the information. Thus, in the device tree display process, the group number is not extracted from the device information.

  Next, a device tree is created in step S61. In this step, a device tree is created by referring to the area ID from the information extracted in step S60, collecting the amplifiers belonging to the same area having the same area ID, and arranging the amplifiers belonging to each area. Is done. In step S62, the created device tree is displayed on the display unit 13, and the device tree display process ends. When the device tree is displayed, the extracted “area name” and “device name” are displayed.

Next, FIG. 16 shows a display example of the device tree displayed on the display unit 13 by performing the device tree display process.
In the monitoring screen 40 shown in FIG. 16, the “Device” tab 41 is selected as the tree type, the above-described device tree display processing is executed, and the device tree is displayed in the tree display unit 42. In the tree display section 42, amplifiers belonging to the area having the area name “Area-1” and amplifiers belonging to the area having the area name “Area-2” are displayed as a tree. In this tree display, it is displayed that three amplifiers “Tx6n”, “Tx4n”, and “Tx6n” belong to the area “Area-1” and “ACD1” belongs. It is displayed that two amplifiers of amplifiers “Tx6n” and “Tx6n” belong to “ACD1”. In addition, it is displayed that the three amplifiers “Tx6n”, “Tx6n”, and “Tx6n” belong to the area “Area-2”. Thus, in the device tree display, ACD5 is displayed and amplifiers are displayed by area. When one of the amplifiers is selected (displayed in white) as shown in FIG. 16 in the device tree display, a status display of the amplifier “Tx6n” belonging to the selected “Area-1” area is displayed on the status display unit 43. Become so. Items displayed on the status display section 43 include the power switch, input level and output level, heat sink temperature, and the like of the channel of the selected amplifier. By monitoring these items, the operational state of each channel of the amplifier can be confirmed.
