BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a diagram showing a schematic configuration of a broadcast radio system 100 according to this embodiment. FIG. 2 is a diagram showing the relationship between the receivers 3 (first group receiver 31, second group receiver 32, third group receiver 33) and installation areas. The broadcast radio system 100 is a digital broadcast radio system related to disaster prevention in municipalities and the like, and is used, for example, for notifying residents of disaster-related information from government agencies in the event of a disaster.

A broadcast radio system 100 includes a master station console 1 , radio equipment 2 , a plurality of receivers 3 , and multilingual communication equipment 5 . The master station console 1, the wireless device 2, and the multilingual communication equipment 5 are installed, for example, in a government building of a municipality or the like. The master station console 1 and the wireless device 2 function as a so-called center station device (master station). communicate with

Specifically, a plurality of receivers 3 installed at predetermined locations receive and output notification information broadcast by radio from a master station console 1, which is a center station device. As a specific example, in a digital broadcast radio system for disaster prevention administration based on the TDMA-TDD system, which is a municipal digital disaster prevention radio communication system in the 60 MHz band (54 to 70 MHz), a center station device (master station) is used using a broadcast radio line. It has a function of communicating between the console 1, the wireless device 2) and the receiver 3 using voice information, other code information, and the like.

The receiver 3 may be applied to a terminal device (child station) that is fixedly installed, or may be applied to a mobile terminal device (child station) such as a mobile phone. Here, the receiver 3 is installed in each area, installed in each house (household) in a municipality, or carried by each person (owner).

The receiver 3 is composed of a first group receiver 31 , a second group receiver 32 and a third group receiver 33 . Specifically, as shown in FIG. 2, the first group receiver 31 is installed in a first area A1, which is a central circular area. The second group receivers 32 are installed in an annular second area A2 outside the second area A2. The third area A3 is installed in an annular third area A3 outside the third area A3. In the first group receiver 31, the second group receiver 32 and the third group receiver 33, the order in which voice messages of a plurality of countries to be acquired are reproduced is set in advance. Alternatively, it receives an instruction of the reproduction order for each group to which it belongs from the master station console 1 .

The first group receiver 31, the second group receiver 32, and the third group receiver 33 are not particularly limited as to whether they are of a fixed installation type or a mobile terminal type. Different types may be installed.
Also, the area division method may be any shape other than the circular shape shown in FIG. In general, in order to notify as many residents as possible, the area to be broadcast for the first time is set as wide as possible. Areas where the first broadcast does not reach are interpolated with other areas. Other than this, for example, you may divide by the area with many specific foreigners.

The multilingual reporting equipment 5 is connected to the master station console 1 and registers the generated multiple multilingual voice messages in the master station console 1 . Specifically, when a message in a predetermined language (generally, the mother tongue) is input as a character message, the multilingual notification equipment 5 translates the message into another language, and converts the character message in the translated language into voice synthesis. By doing so, a voice message is generated and registered in the master station console 1 in association with the translated language type.

In this embodiment, it is included in the broadcast radio system 100 , but it may be connected to the master station console 1 as a device higher than the broadcast radio system 100 .

The master station console 1 transmits a selective call signal between the radio equipment 2 and the receiver 3 using the broadcast radio line in accordance with the registered contents, so that the receiver designated as the called party is called. Activate loudspeaker for 3. After that, the master station console 1 reproduces and outputs the voice messages in a plurality of languages, and the receiver 3 that has received the voice messages outputs the voice messages in a plurality of languages through a loudspeaker connected to itself by time-lag broadcasting.

The receiver 3 reproduces the voice messages in a plurality of languages in the order set by the predetermined reproduction means. At this time, if the first group receiver 31, the second group receiver 32, and the third group receiver 33 reproduce voice messages in the same language at the same time, the sound will not be heard in areas where the sound range of each receiver overlaps. It overlaps and makes it difficult to hear the voice message. Therefore, it is desirable that receivers 3 in different areas simultaneously reproduce voice messages in different languages. The time-lag broadcasting of multilingual voice messages will be specifically described below.

FIG. 3 shows a sequence when a multilingual voice message is broadcast from the multilingual reporting equipment 5 connected to the master station console 1 in the broadcast radio system 100 described above. A manager or the like inputs characters in the first language (here, Japanese) to the multilingual reporting equipment 5 (S1). For example, a message such as "This is emergency XX. The XX river has exceeded the warning water level..." is input.

The multilingual reporting equipment 5 performs multilingual conversion processing of the input message (S2). Here, the input first language (Japanese) is translated and converted into two languages, for example, "English" as the second language and "Chinese" as the third language. After the conversion process, the multilingual reporting equipment 5 requests the server 11 of the master station console 1 to start recording and transfers the recorded voice signal (audio data in each language) (S3). At this time, each language type is added to the recorded voice signal of each language and transferred.

Next, the server 11 of the master station console 1 instructs the main control unit 12 to request recording of the first country (first language) (S4). Further, the main control unit 12 performs disaster prevention wireless recording activation processing (S5). That is, the main control unit 12 utilizes a broadcast radio line between the radio device 2 and the receiver 3 (the first group receiver 31, the second group receiver 32, and the third group receiver 33), A selective calling signal is transmitted to activate the recording function for the receiver 3 . At this time, the language type (Japanese) is transmitted from the wireless device 2 to the receiver 3 in order to indicate in which language the voice message is to be recorded. The instruction to activate the recording function may be broadcast instead of selective calling.

Subsequently, the main control unit 12 outputs the voice message of the first country through the wireless device 2 (S6). The receiver 3 records the voice message of the first country, associates it with the language type (Japanese), and saves it. When the output is completed, the main control unit 12 causes the receivers 3 (the first group receiver 31, the second group receiver 32, and the third group receiver 33) to activate the disaster prevention radio recording via the radio device 2. The end is notified (S7).

When the recording process for the first country ends, the recording process for the second country begins in the same way as that process. That is, the server 11 instructs the main control unit 12 to request recording of the second country (second language) (S8). Further, the main control unit 12 performs disaster prevention wireless recording activation processing (S9). At this time, the language type (English) is transmitted from the wireless device 2 to the receiver 3 .

After starting the receiver 3, the main controller 12 outputs the voice message of the second country through the wireless device 2 (S10). The receiver 3 records the voice message of the second country, associates it with the language type (English), and stores it. When the output ends, the main control unit 12 notifies the receiver 3 via the wireless device 2 that activation of the disaster prevention wireless recording has ended (S11).

When the recording process for the second country ends, the recording process for the third country begins in the same manner as that process. That is, the server 11 instructs the main control unit 12 to request recording of the third country (third language) (S12). Further, the main control unit 12 performs disaster prevention wireless recording activation processing (S13). At this time, the language type (Chinese) is transmitted from the wireless device 2 to the receiver 3 .

After starting the receiver 3, the main controller 12 outputs the third country's voice message via the wireless device 2 (S14). The receiver 3 records the voice message of the third country, associates it with the language type (Chinese), and saves it. When the output ends, the main control unit 12 notifies the receiver 3 via the wireless device 2 that activation of the disaster prevention wireless recording has ended (S15).

After the recording process in the receiver 3 is completed for all the languages, here the languages of the three countries, the next reproduction process is performed (S16-S24). In addition, the receiver 3 stores in advance the language reproduction order according to the area to which the own station belongs, and based on the language reproduction order and the language type linked to the recorded voice message, Determines in which language voice messages are played. In this embodiment, the first group receiver 31 is for the language of the first country, the language for the third country, the language for the second country, the second group receiver 32 is for the language of the second country, the language for the first country , language of the third country, and the third group receiver 33 are set to reproduce the language of the third country, the language of the second country, and the language of the first country in this order. The server 11 first notifies the main control unit 12 to instruct the first reproduction activation (S16). The main control unit 12 causes the radio device 2 to notify the receiver 3 of the first disaster prevention radio reproduction activation (S17). As a result, the master station console 1 can send the first reproduction instruction to the receivers 3 belonging to each area.

At this time, the receiver 3 that has received the notification starts the first reproduction based on the reproduction order of the language according to the area to which the own station belongs. The first group receiver 31 at the time difference A reproduces the voice message of the first country (Japanese). The second group receiver 32 at time difference B reproduces the voice message in the second country (English). The third group receiver 33 at the time difference C reproduces the voice message of the third country (Chinese).

When the reproduction of the voice message with the longest reproduction time among the voice messages in the languages of the three countries is finished, the main control unit 12 instructs all the receivers 3 to end the disaster prevention wireless reproduction activation (S18). The receiver 3 receives the end notification and ends the first reproduction activation.

Next, the server 11 notifies the main control unit 12 to instruct the second reproduction activation (S19). The main control unit 12 causes the radio device 2 to notify the receiver 3 of the second disaster prevention radio reproduction activation (S20). As a result, the master station console 1 can send the second reproduction instruction to the receivers 3 belonging to each area.

At this time, the receiver 3 starts the second reproduction by the notification. The first group receiver 31 at the time difference A reproduces the voice message of the third country (Chinese). The second group receiver 32 at the time difference B reproduces the voice message in the first country (Japanese). The third group receiver 33 at the time difference C reproduces the voice message of the second country (English).

When the reproduction of the voice message with the longest reproduction time among the voice messages in the languages of the three countries is finished, the main control unit 12 instructs all the receivers 3 to end the disaster prevention wireless reproduction activation (S21). The receiver 3 receives the end notification and ends the second playback activation.

Finally, the server 11 notifies the main control unit 12 to instruct the third reproduction activation (S22). The main control unit 12 causes the radio device 2 to notify the receiver 3 of the third disaster prevention radio reproduction activation (S23). As a result, the master station console 1 can send the third reproduction instruction to the receivers 3 belonging to each area.

At this time, the receiver 3 starts reproduction for the third time according to the notification. The first group receiver 31 at the time difference A reproduces the voice message of the second country (English). The second group receiver 32 at time difference B reproduces the voice message in the third country (Chinese). The third group receiver 33 at the time difference C reproduces the voice message of the first country (Japanese).

When the reproduction of the voice message with the longest reproduction time among the voice messages in the languages of the three countries is finished, the main control unit 12 instructs all the receivers 3 to end the disaster prevention wireless reproduction activation (S24). The receiver 3 receives the notification of the end and ends the reproduction activation.

In the above processing, the interval at which the master station console 1 (server 11) transmits the signal for starting reproduction may be determined in advance, or may be changed dynamically according to the content of the broadcast. In the latter case, since the broadcast time (playback time of the voice message) differs for each language, it is preferable to set the broadcast interval according to the language with the longest broadcast time (playback time of the voice message). This prevents the playback of the next language from starting before playback is complete.

Also, although the server 11 outputs the instruction to start reproduction three times, the instruction may be issued only once. That is, the voice message with the longest playback time should be played back the next time after securing the length that can be played back to the end.

As described above, when reproducing a plurality of multilingual voice messages by time-lag broadcasting, even between terminal station devices (receivers 3) whose acoustic transmission ranges of speakers overlap in advance, if different multilingual voice messages are reproduced simultaneously, , it is possible to shorten the overall notification time by using the fact that the recognition of the notification information is not lost. In this case, originally, a period for reproducing the voice messages a total of nine times is required, but in this embodiment, it is possible to perform multilingual staggered broadcasting with only a period for reproducing the voice messages three times.

The present invention has been described above based on the embodiments. It should be understood by those skilled in the art that this embodiment is an example, and that various modifications can be made to the combination of each component, and that such modifications are within the scope of the present invention.

For example, in the first reproduction (steps corresponding to S16 to S18 in FIG. 3), which is the timing of the first message output, the first group receiver 31 with the time difference A, the second group receiver 32 with the time difference B, the time difference C The same first country message is output in any group of receivers 3 of the third group receivers 33 of . In the second and subsequent reproductions, the first group receiver 31, the second group receiver 32, and the third group receiver 33 output voice messages in different languages. When outputting the voice message for the same first country, the receivers 3 of different groups may change the playback speed or playback pitch, for example, to provide a certain degree of discrimination and reduce the difficulty of hearing. .

Also, in this case, since voice messages in the same language cannot be reproduced at the same timing, the first reproduction is inevitably performed by the first group receiver 31, the second group receiver 32, and the second group receiver 32, as in the background art. The third group receiver 33 performs time-lag reproduction, and the same processing as in the above embodiment is performed after the reproduction of the voice message of the second country. That is, each receiver 3 is set to reproduce a predetermined language (in this modification, the language of the first country) for the first time, and time-shifted reproduction is performed in the order according to the group to which the own station belongs. However, since it is not necessary to wait for the recording of all languages, after completing the recording of the first language, start playing the voice message of the first language in parallel with the recording of the second language. good too. The languages of the second and subsequent countries are reproduced after the recording of all the languages is completed in the same manner as described above.
According to this modification, the first report can be broadcast in which the language of the local people with the largest number of people is the first language in any area. Although the first broadcast is time-lag reproduction similar to the conventional one, the number of times of reproduction after the second broadcast can be reduced more than the conventional one.
