<1. Broadcast system configuration>
First, a configuration example of the broadcasting system according to the embodiment of the present invention will be described with reference to FIG. FIG. 1 is an explanatory diagram showing a configuration example of a broadcasting system according to an embodiment of the present invention. As shown in FIG. 1, the broadcasting system 1 according to the embodiment of the present invention includes a receiver 50, a broadcast radio automatic activation device 60, an operation console 10, and a master station device (hereinafter, simply "master station"). It also has 20 and a slave station device (hereinafter, also simply referred to as “slave station”) 30. Broadcast system 1 can correspond to a national instantaneous warning system. Further, the receiver 50, the broadcast radio automatic activation device 60, the operation console 10, and the master station 20 may be installed in the city hall or the like.

The receiver 50 is connected to the network 40 and receives the report number by wire via the network 40. Further, the receiver 50 has an antenna 530 and receives a notification number wirelessly via the antenna 530. For example, the receiver 50 receives the notification number via the network 40 or the antenna 530. Then, the receiver 50 transmits the report number to the broadcast wireless automatic activation device 60 by wire. The receiver 50 may wirelessly transmit the notification number to the broadcast radio automatic activation device 60. Here, the report number is information corresponding to one or more voice data to be broadcast (information for identifying one or more voice data).

In the following, it is assumed that a maximum of 15 voice data correspond to one report number. However, the number of voice data corresponding to one report number is not limited. Further, the type of voice data corresponding to the report number is not limited. For example, the voice data may be a tsunami warning, an eruption warning, an earthquake warning, a seismic intensity information, a weather information, a national protection warning, a special warning, or the like. The report number is transmitted to the receiver 50 from the terminal of a ministry such as the Fire and Disaster Management Agency that manages the national instantaneous warning system. For example, the report number is transmitted from the terminal of the Fire and Disaster Management Agency, but the source of the information is transmitted from the Cabinet Secretariat or the Japan Meteorological Agency, and is transmitted to the receiver 50 via the terminal of the Fire and Disaster Management Agency. Further, the length (reproduction time) of the audio data is not limited. For example, the length of the voice data may be as short as about 2 minutes.

The broadcast wireless automatic activation device 60 receives the report number from the receiver 50 by wire. A switching hub (not shown) may be provided between the receiver 50 and the broadcast radio automatic activation device 60. The switching hub controls to transmit the notification number to the broadcast radio automatic activation device 60 if broadcasting is required according to the notification number. In addition, a rotating light and a display PC are connected to the switching hub, and the switching hub rings a rotating light installed in a predetermined room in the city hall according to the report number, or is used as a display unit of the PC. , The information received by the receiver 50 may be displayed so that the staff can confirm it.

Then, the broadcast wireless automatic activation device 60 transmits the voice data corresponding to the report number received from the receiver 50 by wire to the operation console 10 by wire. Further, the broadcast wireless automatic activation device 60 transmits the group number corresponding to the report number to the operation console 10 by wire. The group number can correspond to the identification signal of the program. The program is stored in the console 10, and detailed information regarding the broadcasting of voice data (for example, voice automatic response service, broadcasting within the agency, volume, etc.) can be set in advance in the program.

The operation console 10 receives the voice data and the group number corresponding to the report number from the broadcast wireless automatic activation device 60. Here, it is assumed that the console 10 is connected to the master station 20 by wire, but the console 10 may be wirelessly connected to the master station 20. The operation console 10 activates a program identified by the received group number, and transmits the voice data received from the broadcast wireless automatic activation device 60 to the master station 20 using the program.

The master station 20 receives the voice data transmitted by the console 10. Then, the master station 20 transmits the voice data received from the operation console 10 to the slave station 30. In the embodiment of the present invention, it is mainly assumed that the master station 20 has an antenna 230 and transmits data received from the console 10 to the slave station 30 wirelessly via the antenna 230. The voice data may be transmitted to the slave station 30 corresponding to the slave station ID specified in advance, or may be transmitted to one or more slave stations 30 belonging to the predetermined group, or all of them. It may be transmitted in a batch to the slave station 30 of. For example, the destination of audio data may be preset as a "broadcast destination" in each program.

The slave station 30 receives the voice data transmitted from the master station 20. In the embodiment of the present invention, it is assumed that the slave station 30 has an antenna 330 unique to the own station, and the audio data transmitted from the master station 20 is wirelessly received via the antenna 330 unique to the own station. To do. Further, the slave station 30 has a speaker 340 unique to its own station, and controls the speaker 340 so that the audio data received from the master station 20 is output from the speaker 340 unique to its own station. The slave station 30 can function as a broadcasting device for broadcasting. Further, the speaker 340 may exist outside the slave station 30. In the present embodiment, an outdoor speaker is assumed as the slave station 30, and the acoustic interference of the slave stations 30 installed adjacent to each other is avoided by staggered broadcasting. However, the slave station 30 may include an indoor speaker. That is, the "broadcast destination" set in the program is not limited to the outdoor speaker, and may include the indoor speaker. Further, it is mainly assumed that the audio data output method by this system uses a real-time method in which when the slave station 30 receives the audio data from the master station 20, the received audio data is output from the speaker in real time.

(Arrangement of issues)
Generally, in the national instantaneous warning system, when the voice data corresponding to the report number received by the receiver 50 is output to the slave station 30, the slave station 30 executes a broadcast based on the voice data once. .. However, if it is broadcast only once from a plurality of broadcasting devices at a time, there is a problem that it is difficult to hear the broadcast contents due to acoustic interference between the broadcasting devices installed adjacent to each other.

Therefore, in the embodiment of the present invention, a technique capable of avoiding acoustic interference by staggered broadcasting in broadcasting audio data acquired from the outside will be mainly described. More specifically, when the operation console 10 defines that staggered broadcasting is performed in the program identified by the group number received from the broadcast wireless automatic activation device 60, the operation console 10 is a slave station. While the audio data is transmitted and broadcast to the slave station 30 belonging to the group whose staggered broadcasting order is "first" among the 30 staggered groups, the audio data is recorded in the audio buffer. Next, the console 10 transmits the audio data recorded in the audio buffer to the slave station 30 belonging to the group whose time difference broadcasting order is "second" among the time difference groups of the slave stations 30 and broadcasts the data. After that, the operation console 10 sequentially performs the time difference broadcasting according to the order set in the time difference group, such as "third time" and "fourth time".

The time difference group information is generated in advance and stored by the operation console 10. Each time difference group consists of one or more slave stations 30 separated in advance to the extent that acoustic interference is avoided. As a result, even if one or more slave stations 30 included in the time difference group broadcast all at once, the difficulty of hearing due to acoustic interference is eliminated. That is, by dividing a large number of slave stations 30 into two or more time difference groups that do not cause acoustic interference and sequentially broadcasting each time difference group, it is possible to avoid difficulty in hearing due to acoustic interference. The number of time difference groups is not particularly limited, but for example, up to 5 or 6 may be set. In addition, it is possible to define in the program whether or not such staggered broadcasting is performed. In the program, it is also possible to define a batch broadcast that broadcasts from one or more predetermined slave stations 30 all at once. This is because, depending on the content of the alarm, it is more urgent than eliminating the difficulty of hearing due to acoustic interference, and even if the content is difficult to hear, it may be more important to promptly inform that some kind of warning has occurred.

The configuration example of the broadcasting system 1 according to the embodiment of the present invention has been described above. Subsequently, a configuration example of the broadcast radio automatic activation device 60 and the console 10 included in the broadcasting system 1 will be specifically described.

<3. Broadcast system function details>
Subsequently, the functional details of the broadcasting system 1 according to the embodiment of the present invention will be described with reference to FIG.

FIG. 4 is a diagram for explaining the functional details of the broadcasting system 1 according to the embodiment of the present invention. As shown in FIG. 4, the receiver 50 receives the notification number via the network 40 or the antenna 530 (step S10).

Next, the notification number received by the receiver 50 (for example, as a number indicating any of 01H to FFH) is transmitted to the broadcast radio automatic activation device 60 (step S11). In the broadcast wireless automatic activation device 60, the storage unit 620 stores the internal setting information 621 in which the report number, the voice data (up to 15 voice data), and the group number are associated with each other. When the broadcast wireless automatic activation device 60 receives the report number by the receiving unit 630, the control unit 610 receives the voice data and the group number corresponding to the received report number from the internal setting information 621 stored in the storage unit 620. To get.

Here, FIG. 5 shows an example of the internal setting information 621. As shown in the upper part of FIG. 5, in the internal setting information 621, a report number, a sound source file (an example of voice data), and a group number are associated with each other. In the example shown in FIG. 5, for example, it is assumed that a maximum of 15 sound source files correspond to one report number.

In the example shown in FIG. 5, the group number is represented by a binary number corresponding to, for example, seven contact signals (for example, an ON signal via at least one of group contacts 1 to 7 shown in FIG. 4). the program of 2 ⁷ = 127 are selectable. The group number and the program number have a one-to-one correspondence, and the number is not particularly limited, but the program may be set up to 127, for example.

Subsequently, the control unit 610 controls the communication unit 640 so that the group number acquired from the internal setting information 621 is output to the operation console 10 by the communication unit 640. That is, for example, the control unit 610 outputs an ON signal to the operation console 10 via at least one of the group contacts 1 to 7 (step S12). Further, the control unit 610 controls the communication unit 640 so that the broadcast start signal (for example, the ON signal via the broadcast start contact shown in FIG. 4) is output to the operation console 10 by the communication unit 640 (step S13). ). The broadcast start signal and the group number may be output substantially at the same time, or the broadcast start signal may be output first.

Next, when the operation console 10 receives the group number by the communication unit 130, the control unit 110 starts the program corresponding to the received group number. The program is stored in the storage unit 120 of the operation console 10 as the program table 121. Here, an example of the program table 121 is shown in the lower part of FIG. As shown in the lower part of FIG. 5, in the program table 121, the program contents (for example, broadcast destination, volume, presence / absence of voice automatic response service, and presence / absence of staggered broadcast) corresponding to the program number are set (defined) in advance. ing. Here, it is assumed that the control unit 110 converts the group number (ON signal via at least one of the group contacts 1 to 7) received from the broadcast wireless automatic activation device 60 from a binary number to a decimal number. ..

Next, when the control unit 110 receives the broadcast start signal by the communication unit 130, the control unit 110 transmits the broadcast start signal to the slave station 30 via the master station 20 (step S14). Specifically, the control unit 110 transmits a broadcast start signal to the slave station 30 defined in the "broadcast destination" of the program. In the example shown in FIG. 5, for example, when the broadcast destination is "group A", the control unit 110 transmits a broadcast start signal to one or more slave stations 30 belonging to group A. Such a broadcast destination group is preset and stored as broadcast destination group information in the storage unit 120 of the operation console 10. Further, all the slave stations 30 may be targeted by setting the broadcast destination as "collective".

Further, when "time difference broadcasting" is defined (set) as "yes" in the program, the control unit 110 refers to the time difference table 122 stored in the storage unit 120, and the order of the time difference broadcasting is "1". A broadcast start signal is transmitted to one or more slave stations 30 that are "third" (that is, included in the staggered broadcast group in which the staggered broadcast is performed for the first time). Here, FIG. 6 shows an example of the time difference table 122 according to the present embodiment. As shown in FIG. 6, in the time difference table 122, the ID (slave station number) of the slave station 30 and the order of the time difference broadcast are associated with each other. According to the time difference table 122 shown in FIG. 6, the slave station 30 of ID: 001, ID: 004, ID: 007, ... Can be regarded as belonging to the first time difference broadcasting group. Further, according to the time difference table 122 shown in FIG. 6, the slave station 30 of ID: 002, ID: 005, ID: 008, ... Can be regarded as belonging to the second time difference broadcasting group.

In the present embodiment, such a plurality of staggered broadcasting groups are preset. It should be noted that one or more slave stations 30 in each group are installed at positions separated from each other to the extent that acoustic interference does not occur even if broadcasting is performed at the same time. Further, when the time difference broadcast is "Yes" and the broadcast destination is "Batch", the control unit 110 determines the time difference group for all the slave stations 30 registered in the time difference table 122. May be good. On the other hand, when there is a time difference broadcast "Yes" and the broadcast destination group is specified such as "Group A", the control unit 110 is a slave station 30 of the group A registered in the time difference table 122. The time difference group may be determined for.

Next, the control unit 110 assumes that the slave station 30 has been activated when a predetermined time (for example, 10 seconds or the like, which is the time required to activate the slave station 30) has elapsed from the transmission of the broadcast activation signal, and the activation completion signal (for example, FIG. The communication unit 130 is controlled so as to transmit the ON signal via the activation completion contact shown in 4) to the broadcast wireless automatic activation device 60 (step S15).

Next, when the communication unit 640 receives the activation completion signal in the broadcast wireless automatic activation device 60, the control unit 610 outputs the voice data acquired from the storage unit 620 to the operation console 10 by the communication unit 640. The communication unit 640 is controlled so as to (step S16).

Next, when the voice data is received by the communication unit 130 on the operation console 10, the control unit 110 sends the voice data received by the communication unit 130 to the slave station via the master station 20 by the function of the activated program. The transmission unit 140 is controlled so as to be transmitted to 30 (the slave station 30 which has been activated by transmitting the broadcast activation signal in step S14) (step S17). When the audio data is received by the antenna 230 at the master station 20, the audio data is transferred to the slave station 30 by the antenna 230. Then, when the audio data is received by the antenna 330 in the slave station 30, the audio data is output by the speaker 340. As a result, the first broadcast by the slave station 30 is performed.

At this time, the control unit 110 can also control the slave station 30 to output audio data at the “volume” defined in the program. For example, when "volume" is defined as "normal", the control unit 110 controls the slave station 30 to output at a volume already set. On the other hand, when "volume" is defined as "forced", the control unit 110 controls to output at the maximum volume regardless of the volume already set on the slave station 30 side.

Further, when the started program defines "with staggered broadcasting", the control unit 110 records the voice data received by the communication unit 130 in the voice buffer 121. The audio data stored in the audio buffer 121 is used for the second and subsequent staggered broadcasts. If the program does not define "with staggered broadcasting" (for example, if it is defined as "without staggered broadcasting"), the control unit 110 transfers the audio data received by the communication unit 130 to the audio buffer 121. Control to broadcast only once without recording.

Then, when the control unit 610 finishes outputting the voice data corresponding to the report number (when the reproduction ends), the broadcast end radio automatic activation device 60 sends a broadcast end signal (for example, the broadcast end contact shown in FIG. 4). The communication unit 640 is controlled so as to transmit the ON signal) to the operation console 10 (S18).

The console 10 that has received the broadcast end signal ends the first staggered broadcast, but then controls to perform the second staggered broadcast. Specifically, the control unit 110 refers to the time difference table 122, and transmits a broadcast start signal from the transmission unit 140 to the slave station 30 included in the second time difference broadcast group via the master station 20. Control to do. Next, the control unit 110 stores in the voice buffer 123 assuming that the slave station 30 has been activated when a predetermined time (for example, 10 seconds or the like, which is the time required to activate the slave station 30) has elapsed from the transmission of the broadcast activation signal. The transmission unit 140 is controlled so that the voice data is transmitted to the slave station 30 via the master station 20. When the audio data is received by the antenna 230 at the master station 20, the audio data is transferred to the slave station 30 by the antenna 230. Then, when the audio data is received by the antenna 330 in the slave station 30, the audio data is output by the speaker 340. As a result, broadcasting can be performed from one or more slave stations 30 belonging to the next time difference group (second time difference broadcasting group). Such staggered broadcasting may be sequentially performed for each set staggered broadcasting group.

Here, the staggered broadcasting according to the present embodiment will be described with reference to FIG. 7. As shown in FIG. 7, for example, when there are slave stations 30a to 30e, in the first staggered broadcast, broadcasts are performed from the slave stations 30a and 30d that are installed apart from each other, and in the second staggered broadcast, the slave stations 30a and 30d are broadcast. By broadcasting from the slave station 30e and the slave station 30b, which are also separated from each other, and broadcasting from the slave station 30c in the third staggered broadcasting, it is possible to avoid acoustic interference.
