Abstract

PROBLEM TO BE SOLVED: To solve the problem that a disaster prevention radio voice message broadcasted by a municipality and the like with the use of an outdoor loudspeaker is inaudible in houses due to, for example, structures of the houses and weather conditions.SOLUTION: The indoor alarm system receives disaster prevention radio waves, and after adding thereto a delay required for an appropriate alarm, digitizes and sends a voice message to a live distribution server. The server transmits, to each terminal installed in households, a command signal to access to the live distribution server through the Internet line, and the like. The indoor alarm system has a configuration in which the terminals that have received the command signal access the live distribution server to receive digital signals from the server such that the message is alarmed through speakers of the terminals and a configuration in which the digitalized voice message is made into a file to be accumulated, and upon a request from, for example, a user who has missed the message, the file of the message is transmitted to the terminal of the user to be reproduced through the speaker of the terminal. These configurations enable the disaster prevention radio massage to be heard even in houses.SELECTED DRAWING: Figure 1

Description

The present invention relates to information transmission of voice messages for indoor disaster prevention radio.

National governments and governments nationwide use disaster prevention radio as a means of communicating disaster prevention information and emergency information to all residents. In general, disaster prevention radio is wirelessly transmitted from a fixed station (consisting of a broadcasting device such as a transmitter and a command desk, a transmission antenna, a power supply unit, etc.) installed in a local government or government office, disaster prevention center, etc. A loudspeaker station transmitted to a loudspeaker station installed in an administrative facility or the like receives the transmitted radio wave and broadcasts a chime or a voice message from the loudspeaker. Today, it is indispensable as information protecting the lives of residents from natural disasters such as heavy rain, earth and sand disasters, and tsunamis.

However, most disaster prevention radio loudspeakers are installed outdoors. For this reason, even in high-rise apartments and general houses, the sound is drowned out in cases where it is difficult to hear broadcast messages in air-conditioned rooms or in heavy rain conditions such as actual torrential rain. There are also reports of cases in which the role of information transmission in an emergency was not fulfilled.

As countermeasures against these, there is a service for transmitting and providing the disaster prevention information to users registered in advance using e-mail, and a mechanism for broadcasting the information on a community channel or community FM of a local cable TV station. is there. However, in the case of information transmission by e-mail, there is a case where the mobile phone is set to manner mode or in a bag, etc. There was a situation where the family members went out and there was no way for other family members who stayed at home to receive emergency information. In the first place, there is a problem that only the person who owns the mobile phone and has registered the e-mail address in advance to receive the disaster prevention information from the local government / administration has the problem. On the other hand, even in the case of information transmission using broadcasting on the cable channel community channel or community FM, the residents can watch the program together with the community channel or community FM before the emergency information is broadcast, It is premised on listening. If other channels or broadcasting stations are being selected, or if the TV or radio is not turned on, it is difficult to obtain emergency information from the local government or government from the TV or radio. .

The problem to be solved is that when emergency information from local governments and governments is broadcast from the disaster prevention radio's loudspeaker stations, the people in the house are affected by the structure of the house, the weather conditions, the neighboring environment, etc. The broadcast content may not be heard accurately.
As described above, the present invention solves the problem of how to create a state in which urgent information from the local government or the government to be transmitted by the disaster prevention radio can be reliably transmitted even if the inhabitant is in the house.

In addition, the disaster prevention radio of local governments and governments may be difficult to refurbish after the system is built and the budget for the repair costs. It is a further problem to be solved.

In order to solve these problems, the present invention is provided with a receiving device equivalent to receiving radio waves by a disaster prevention radio loudspeaker station, and the radio waves of the disaster prevention radio transmitted from the local government or the administration by this receiving device. The point to receive, the point to demodulate the received disaster prevention radio wave, digitize it, digitize it, the point to distribute the digitized voice live using a communication line such as the Internet, When executing the distribution, the activation signal is distributed in advance to the terminal installed in each home, the server that accesses the server that performs live distribution from the terminal side, and the same voice message as the content broadcast on the disaster prevention radio loudspeaker station The point to be notified from the speaker on the terminal side. And at the same time that the digitized audio is distributed live, it is converted into a file and on-demand (the information is distributed and provided via a communication line such as the Internet in response to the user's request as a measure for the user to miss) The above-mentioned problem is solved by combining these means and the corresponding points.

In addition, the present invention provides a receiving device equivalent to receiving radio waves in a disaster prevention radio loudspeaker as described above, and by using means for constructing a system after this receiving device, local governments and administrations are currently There is no need to change any disaster-prevention radio transmission system.

When local governments and governments broadcast emergency information etc. using disaster prevention radio, the residents in the house are in a closed room or under heavy rain conditions such as torrential rain, etc. Even if it is difficult to hear the message flowing from the speaker, the same voice message as that broadcast by the disaster prevention radio's loudspeaker station is emitted from the built-in or external speaker such as IP-STB installed in the home. By being reported, there is an advantage that the voice message of the disaster prevention radio can be heard in the house without being affected by the structure of the house, weather conditions, neighboring environment, etc., and the situation can be grasped .

On the other hand, even if the resident has missed the emergency information broadcast or notification for some reason, the server's voice file can be accessed on demand from a terminal such as an IP-STB installed in the home. Thus, there is an advantage that the voice message can be heard and the emergency information and the like announced by the local government or the government can be recognized.

In addition, since the present invention is a mechanism constructed after the disaster prevention radio receiver, it is not necessary to renovate the current disaster prevention radio transmission system. There is an advantage that can be reached.

It is explanatory drawing which showed the mechanism for issuing the disaster prevention radio | voice voice message with the speaker of a terminal side, after receiving the radio wave of the disaster prevention radio | wireless transmitted from the local government or the administration.

After receiving the disaster prevention radio wave transmitted from the local government or the government, the objective of being issued the disaster prevention radio voice message by the speaker on the terminal side was realized with the minimum number of devices.
