Description

  The present invention relates to a district disaster prevention radio system, and more particularly, to a district disaster prevention radio system using a plurality of types of information communication terminals such as radio, television, and mobile phone for emergency evacuation guidance and information collection.

  As a means of protecting the lives and property of local residents from disasters such as typhoons, floods, fires, and earthquakes, the introduction of regional disaster prevention (wireless) systems is being promoted. In addition, it is operated to conduct evacuation guidance. As a disaster prevention measure, emergency information transmission means are important, but a comprehensive system including the establishment of a disaster response headquarters, evacuation facilities, and securing relief supplies is often called a disaster prevention system. Here, when discussing an information transmission system including a wired communication facility, it is called a disaster prevention radio.

Examples of systems that transmit information directly to residents in the event of a disaster include regional disaster prevention (administration) radio systems or regional public relations radio systems that are introduced by municipalities as shown in FIG. The disaster prevention (wireless) system for each prefecture is grouped as a nationwide disaster prevention (wireless) system.
The local disaster prevention (radio) system for each municipality receives and demodulates the radio signal transmitted from the master station equipment 20 installed in the municipal office by the loudspeaker terminals located in various places of the village, and performs loudspeaking broadcasting by the trumpet speaker. In addition, in areas where there is a lot of noise and snow, dedicated home-side reception terminals are arranged in each household to receive information indoors.

Furthermore, as disclosed in Patent Document 1, there is one that performs evacuation guidance at the time of a disaster using a mobile phone (mobile phone terminal) having a position information detection function that has been widely spread in recent years. In this method, an emergency call signal with an unidentified number of mobile phone terminals located in a target area from a disaster prevention radio master station, an identifier that is emergency information, each call number (phone number), and a return request code with location information is attached. Send. The disaster prevention radio master station that has received the position information returned from the mobile phone terminal that has received this is configured to provide the nearest shelter information to the location where each mobile phone terminal is located. According to this system, if the nearest evacuation site from the current position is informed and information including location information exceeding the capacity is transmitted, further functional evacuation guidance is possible.

However, in the conventional disaster prevention radio system as described above, when one system such as a municipal disaster prevention radio system is the main information transmission means, if the master station device or the loudspeaker terminal in each district stops functioning, no information transmission is possible. This means will be lost. Therefore, measures such as duplication of working / standby for main facilities or provision of emergency power supply facilities have been taken, but it has been reported that the damage caused by information failure due to system failure at the time of emergency This is the current situation. Further, since information transmission from the master station is mainly performed, local disaster occurrence information transmission is difficult to be performed quickly and accurately. For example, inundation of rivers, landslides, debris flows, and mountain tsunamis caused by torrential rains in mountainous areas, even if some local people discover the precursors, there is no way to convey them and evacuation guidance The tragedy of precious life being lost due to delay is repeated. In addition, large-scale earthquakes are predicted throughout the country, and attempts are being made to simulate evacuation guidance assuming the destruction of transportation facilities and facilities, the collapse of communication systems, and so on.
Furthermore, not only natural disasters but also terrorist incidents and riot-related disputes have occurred in various parts of the world in recent years, and there are concerns about catastrophic events during disasters, particularly in large cities. The delay is pointed out.

  The present invention has been made in view of such problems in the conventional disaster prevention radio system, and is a communication network in which various communication facilities and communication terminals located in the jurisdiction are comprehensively incorporated in the system.

Hereinafter, the present invention will be described in detail with reference to embodiments shown in the drawings. However, the technical terms, components, types, combinations, shapes, relative arrangements, and the like described in this embodiment are not intended to limit the scope of the present invention only to specific examples unless otherwise specified. Only.
FIG. 1 is a schematic block diagram for explaining the outline of a district disaster prevention radio system according to the present invention. Here, in the present invention, it is distinguished from a conventionally used regional disaster prevention radio system, and it is referred to as a district disaster prevention radio system with the intention of indicating a smaller area than that, but only a conceptual difference is intended. However, the scope of application of the present invention is not limited, and there is no problem in applying the present invention to a relatively wide area as in the prior art.
In FIG. 1, 1 is a unit block of the district disaster prevention radio system according to the present invention. In the district disaster prevention radio system 1 shown in this example, reference numeral 2 denotes a district disaster prevention station, which is provided assuming a relatively narrow district such as a neighborhood association of each district as a jurisdiction range. A function of performing transmission / reception with a wireless terminal, a repeater function, a base station (base station) function, a function of converting information by using different communication media, and the like. In addition, the wireless terminals arranged or located within the jurisdiction include as much as possible all communication terminals within the jurisdiction. For example, the loudspeaker notification terminal 3 conventionally known as a terminal of a disaster prevention radio system, In addition to the individual reception terminal 4, a mobile phone terminal 5, a public broadcasting terminal 6 such as a radio or a portable TV, an administrative radio communication terminal 7 often grounded to a public hall, an leisure radio terminal 8 such as an amateur radio or a personal radio Although not shown, a selective call receiving terminal or the like that is owned by a fire department member, a municipal office staff, a fire brigade member, or the like is conceivable.

The present invention is characterized in that, in addition to the district disaster prevention radio station 2 corresponding to the master station device of the conventional disaster prevention administrative radio system, the loudspeaker notification terminal 3, the door-to-door reception terminal 4, and the administrative radio communication terminal 7, the mobile phone terminal 5, radio At least two or more different types of communication terminals such as public broadcast terminals 6 such as mobile TVs and leisure radio terminals 8 such as amateur radios and personal radios have been comprehensively incorporated into the system.
Then, the district disaster prevention station 2 performs information transmission in correspondence with, for example, the following different types of communication terminals in order to legally transmit necessary information to these wireless terminals. It is configured.

First, the information transmission function as disaster prevention radio such as simultaneous notification, selection notification, emergency notification, etc., for the door-to-door reception terminal 4 or the loudspeaker notification terminal 3 for the disaster prevention radio system and the selective call reception terminal such as the pager or the commander. This is a system similar to the conventional system and will not require any particular explanation.
Necessary information is transmitted to the radio terminals and television terminals in the district to the public broadcasting terminals 6 such as radio and television by a specific frequency or a specially permitted general broadcasting frequency. Sending regional information, especially neighborhood association-like regional information, directly from the district disaster prevention radio station 2 to the public broadcast receiving radio terminal or television terminal is difficult to implement immediately because there are various legal regulations. However, in recent years, since many community FM stations have been constructed in each district, it is possible to construct systematically so that emergency information can be broadcast in the event of a disaster in cooperation with the broadcasting station. In addition, it will be necessary to legally prepare to use radio waves for public broadcasting locally as an emergency evacuation measure in the event of a disaster.

  For mobile phone terminals 5 connected to the public network, each telephone number registered in advance as a resident in the district is stored in the memory device of the district disaster prevention radio station 2, and in the event of an emergency call, The mobile telephones are sequentially called to contact each other, or the mail addresses of the respective mobile telephones are stored, and information is transmitted to each address by push-type mail delivery. Furthermore, if a mobile phone terminal that is widely used by each person can be used for disaster prevention, it will be an extremely useful information transmission means for disaster prevention, so each mobile phone can be used directly from the disaster prevention radio stage using a specific frequency / channel. It is necessary to make legal and system improvements so that telephone terminals can be contacted in case of emergency evacuation. In recent years, a means for receiving television broadcasts using a specific channel has been established as one-segment broadcasting, so that disaster prevention information transmission using a similar system may be possible.

Information is transmitted to a leisure radio terminal 8 such as an amateur radio or a personal radio via a preset emergency call frequency or channel, or via a pre-registered terminal call number / code. Configure the system to call and communicate the necessary information. As a legal response, it may be useful to collaborate with amateur radio operators in the district in the event of an emergency and to communicate information under the cooperation.
As described above, if a system is constructed in which a large number of communication terminals belonging to various types of communication systems located in the target area are comprehensively incorporated into information transmission means in an emergency, for example, several systems can be obtained. Even in the event of catastrophic damage during a disaster such as an earthquake or typhoon, evacuation information can be communicated to local residents using any surviving system. Considering that the most necessary information at the time of disaster is accurate information, this system is extremely useful for disaster prevention.

FIG. 2 is a system conceptual diagram when the above-described district disaster prevention radio system 1 is constructed, for example, for each neighborhood association, and each is incorporated as a block of a wide area disaster prevention radio (information) system at the municipal level. With this configuration, if you use a wireless system locally and communicate the necessary information to each individual via radio and television, you can quickly and reliably convey information according to the situation and circumstances of each district. An accurate evacuation guidance will be provided. In addition, as shown in the figure, the communication terminal at each individual level may extend over a plurality of districts.
In the above description, the case where information is unilaterally transmitted from the district disaster prevention radio station 1 to each terminal has been described. Further, the radio terminal having the transmission function and the district disaster prevention radio station 1 are directly connected to each other or each terminal is connected. It can also be configured to collect information according to the district by transmitting and receiving through the communication system to which it belongs. In other words, among the communication terminals described above, the mobile phone terminal and leisure radio terminal having a transmission function and the district disaster prevention station 1 can directly communicate to collect local disaster information.

  As described above, the mobile phone terminal 5 and the district disaster prevention station 2 can directly talk with each other by calling each telephone number registered in advance as a resident in the district and via a normal public line (switch). There may be a method of making a telephone call and a method of connecting the disaster prevention center 2 and the nearest exchange station with a dedicated line. Furthermore, it would be even more preferable if the area disaster prevention station 2 and the mobile phone terminal can be directly connected in preparation for the case where the public line cannot be used due to a large-scale earthquake or the like. At this time, when the simultaneous transmission / reception system construction is a major issue, a press talk system call using a mobile phone terminal may be used. In addition, in the case of including a plurality of communication systems, in one communication system, it is possible to transmit information from the downlink, that is, from the district disaster prevention station to the receiving terminal, but it is impossible to perform uplink, and in other communication systems, On the other hand, if an uplink is possible and a downlink is not possible, the advantage of combining a plurality of systems can be utilized by combining the surviving lines of both methods so that information can be exchanged. Needless to say, legal arrangements are necessary for such communication modes.

  FIG. 3 is a diagram showing a modification of the present invention. In this example, in a district where a community FM station exists, the broadcasting station is equipped with a system control unit having a repeater function, a base station function, and a conversion function, and basically a wide area is managed through FM broadcasting. Since daily broadcasting is performed, it becomes possible to function as a district disaster prevention station that transmits information mainly through FM broadcasting in the event of a disaster, and at the same time, mobile phone terminals in the jurisdiction area as described above Disaster prevention information transmission using communication terminals such as. In constructing this system, one FM community can function as a district disaster prevention station for a relatively large area, and as shown in FIG. ) By providing each district disaster prevention station function corresponding to each, detailed information transmission at the neighborhood association level becomes possible, and the present invention can be implemented economically.

  FIG. 4 is an image of a prefectural disaster prevention radio system including the district disaster prevention system of the present invention. A municipal disaster prevention radio system 10 that integrates the district disaster prevention radio system 1 according to the present invention is installed on a municipal basis. The plurality of municipal disaster prevention radio systems are controlled as a prefecture disaster prevention system 12 on a prefecture basis. In addition, if the disaster prevention system integrated in the pyramid type is integrated into the disaster prevention system integrated by each prefecture, the disaster prevention system integrated by the country not shown in the figure, the most important part of direct contact with the residents The district disaster prevention radio system of the present invention can be utilized as an information transmission means.

  FIG. 5 is a block diagram for explaining a modified embodiment of the present invention. In this example, an example of security means for collecting information from a communication terminal is shown. When the district disaster prevention radio station 2 receives information from the mobile phone terminal 5 within the jurisdiction, the disaster prevention radio terminal 7, the amateur radio terminal 8, etc., it is confirmed that those operators are definitely qualified persons It is essential to do that. For example, the authenticity of the collected information can be ensured if the administrator is a valid administrator of the administrative wireless communication device or if the person who sends the information via the mobile phone terminal can be confirmed. Therefore, as shown in FIG. 5, in the mobile phone terminal 5, a mobile phone with a video phone function is used, and when receiving information, the video of the operator's face is always received in real time by the video phone. In addition, in a wireless device without a TV image transmission function, a preset password and ID number are input from the keyboard, and it is confirmed that they are stored in the memory of the district disaster prevention station 2. Alternatively, biometric authentication means such as fingerprints, voiceprints, and irises may be used instead of keyword input. In this way, if the operator can confirm, it is possible to adopt a usage method in which the information is directly transferred from the district disaster prevention station 10 to the wireless terminal in the district. According to this method, the information received at the district disaster prevention station can be transmitted to related terminals in real time without taking time and effort to retransmit to each terminal. Furthermore, since necessary information can be directly flowed to other district disaster prevention stations and the master station of the upper-level municipal disaster prevention system, it will be useful for prompt information transmission.

The present invention need not be limited to the above-described embodiments, and various modifications are possible. For example, among communication terminals within the jurisdiction, wireless terminals that have a transmission function for the district disaster prevention station may be confused when transmitting without permission. You can also. As a specific method, for example, after transmitting a digital signal or the like of a special code set in advance to the target communication terminal, control is performed so as to allow transmission from the terminal only for a required period. Although there may be other various means, they may be used.
In addition, in the district disaster prevention station 2, in addition to transmission / reception with the above-mentioned terminal, a function to relay a transmission signal from the communication terminal to another communication terminal, information from a higher level disaster prevention system and other district disaster prevention radio systems is required. A function to transfer to a different communication terminal, a function to convert different types of data formats and send it to the terminal of the other communication system, a repeater function, a base station function, etc. It is preferable to perform the operation.
