Description

The present invention relates to information transmission and information reception processing of a diversified disaster prevention broadcasting system, and transmits and receives information by voice.

The disaster prevention radio system is a radio system that is built by the national government, local governments, and private companies for the purpose of securing means for collecting and transmitting disaster information in the event of an emergency disaster. However, with the disaster prevention radio system alone, if the operation console (sending side) or receiving device breaks down due to a disaster, no information can be delivered to the residents (if the earthquake breaks, a subsequent tsunami warning is broadcast. Etc.) In addition, the broadcaster always needs to broadcast from the command desk, and there is a risk that the broadcaster will be delayed and sacrificed.
On the other hand, in patent document 1, even if the radio system for disaster prevention breaks down, it is configured so that voice data can be received from the mobile communication terminal and can be broadcasted in case the radio system fails. It is possible to receive voice data from a mobile communication terminal of a mobile radio communication system and perform voice broadcasting.

However, based on the lessons learned from the 3.11 Great East Japan Earthquake, it is not sufficient to use only one method of information for residents in response to disasters. Diversification of information transmission methods for residents is indispensable.
There are methods such as disaster prevention administrative radio, disaster FM broadcast (community FM broadcast), IP disaster prevention broadcast, area mail, disaster prevention mail, disaster prevention portal, etc. as a means of information transmission from the government office about disaster prevention to residents. In the case of diversification, the government office must transmit information corresponding to each information transmission means. Therefore, various types of transmissions are required, such as broadcasting from the microphone of the command console, broadcasting from the microphone of FM broadcasting equipment, broadcasting from a mobile phone / landline phone, delivery of mail text from a PC screen, delivery of information from a portal update screen, etc. Become.

However, at the time of disasters such as earthquake / tsunami, there is no room to send information according to each information transmission means, and it is an urgent task to simplify and speed up information sending processing when diversified. Yes. In addition, since it is difficult for the government to introduce all system devices when diversifying, it is desirable to use mobile information terminals (smartphones, mobile phones, etc.) that are widely used by residents.
In order to solve the above-mentioned problems, a variety of broadcasting (transmission) and information transmission means is realized, and broadcasting is possible anytime and anywhere, and various information transmission means (disaster management radio system, disaster FM broadcasting) System, IP disaster prevention broadcasting system, area mail system, disaster prevention mail system, disaster prevention portal system) enables the information distribution to be performed automatically or in one operation.

As shown in FIG. 1, for example, as shown in FIG. 1, broadcast activation (transmission) is integrated into the system, and broadcast can be transmitted anytime / anywhere with no operation (automatic) or one operation (mobile phone). At the same time, various information transmission means are coordinated on the system side, such as disaster prevention administrative radio system, disaster FM broadcasting system, IP disaster prevention broadcasting system, area mail system, disaster prevention mail system, disaster prevention portal system, etc. Possible configuration.

According to the second aspect of the present invention, the contents of the disaster prevention broadcast can be reproduced as an audio file / or real-time streaming, so that the latest to past broadcasts can be listened to arbitrarily even at remote locations.

According to the third aspect of the present invention, in the digital simple radio, when a specific control signal is transmitted and the signal is received at the receiving side, the music in the sound repeater can be reproduced.

Claim 4 adopts a configuration in which the power of the amplifier is automatically turned on when the sound is received, and the power of the amplifier is automatically turned off when the reception of the sound is finished. There is no need to keep it.

Since Claim 5 adopts a configuration that can automatically listen to the contents of the disaster prevention broadcast in real time from the smartphone, it can solve the problem that the disaster prevention broadcast cannot be heard unless it is in a limited place. .

Claim 6 links all the various information transmission methods related to disaster prevention such as disaster prevention administrative radio, disaster FM broadcast, IP disaster prevention broadcast, area mail, disaster prevention mail, disaster prevention portal, and information by one operation or automatic, ie no operation. It is a disaster prevention voice delivery method characterized by performing the transmission.

Conventionally, if the operation command console (sending side) or receiving device breaks down due to a disaster etc. with the disaster prevention wireless system alone, no information can be delivered to the residents (if it breaks due to an earthquake, a subsequent tsunami warning is broadcast. Etc.) In addition, the broadcaster always needs to broadcast from the command desk, and there is a risk that the broadcaster will be delayed and sacrificed. However, according to claim 1 of the present invention, broadcast activation (transmission) is integrated into the system, and broadcast can be transmitted anytime / anywhere with one operation (mobile phone) or no operation (automatic). At the same time, it is possible to distribute information by various information transmission means such as a disaster prevention administrative radio system, a disaster FM broadcast system, an IP disaster prevention broadcast system, an area mail system, a disaster prevention mail system, a disaster prevention portal system, etc.

Furthermore, conventional disaster prevention broadcasting systems have problems such as not being able to hear them unless they are close to the speakers in real time in order to listen to the broadcasts. However, according to the second aspect of the present invention, since the contents of the disaster prevention broadcast can be reproduced as an audio file / or real-time streaming, the latest to past broadcasts can be listened to arbitrarily even at a remote place.

Moreover, since the conventional digital simple radio can transmit only human voice, it has not been possible to arbitrarily broadcast a time signal or the like by music. However, in the digital simple radio according to claim 3 of the present invention, When the control signal is transmitted and the signal is received at the receiving side, the music in the sound repeater can be reproduced.

In addition, amplifiers that are linked to conventional digital simple radio need to be turned on at all times, even during broadcasting, which causes unnecessary power consumption, increasing costs and limited power sources (batteries during power outages). Etc.).
However, according to claim 4 of the present invention, the power of the amplifier is automatically turned on when the sound is received, and the power of the amplifier is automatically turned off when the reception of the sound is completed. There is no need to keep the power on at all times, and running costs are reduced.

In the conventional disaster prevention broadcasting system, the disaster prevention broadcast can be listened only by the outdoor loudspeaker installed by the local government side or the dedicated indoor individual receiver, but according to claim 5 of the present invention, the disaster prevention broadcast can be obtained. It is possible to listen to what is being carried out automatically in real time by voice from a smartphone that you usually carry around, making it suitable for emergency disaster prevention broadcasting.

As in claim 6, various information transmission methods related to disaster prevention such as disaster prevention administrative radio, disaster FM broadcast, IP disaster prevention broadcast, area mail, disaster prevention mail, disaster prevention portal are all linked to one operation or automatic, ie no operation. Therefore, it is possible to send disaster prevention broadcasts anytime and anywhere, and it is possible to realize information distribution by various information transmission means through cooperation on the system side.
