Description

  In the event of a disaster, for example, whether supplies such as water, food, blankets, clothes, gasoline, kerosene, etc. are available at convenience stores, other stores, gas stations, etc., and whether hospitals can accept them. In addition, information on each base, such as whether the safety of major bridges and buildings is ensured, and whether toilets are usable, is important for disaster victims and local residents.

  The present invention relates to an electronic guidance system for disaster prevention with an improved disaster prevention function, and uses radio to provide information on relief supplies at each base to disaster victims and local residents at the time of a disaster, disaster victims and local residents. Information for safely guiding is provided using an electronic guide board.

  In the conventional method, for example, as shown in Patent Document 1, when the disaster prevention center grasps disaster information using a public line or the like, the contents are received by a plurality of audio broadcasting receivers using a disaster prevention radio system. The method of notifying victims and local residents using outdoor speakers connected to these audio broadcasting receivers was used.

  Hereinafter, an example of the conventional disaster prevention radio system shown in FIG. 16 will be described. The large-scale network 1 such as a public line or a mobile phone system is also an important information transmission means for notifying the disaster prevention center of the disaster situation in the area and conducting disaster prevention activities. Information obtained at the disaster prevention center 2 is sent to the respective disaster prevention radio base stations 4 and 5 via the disaster prevention control station 3. Each of the disaster prevention radio base stations 4 and 5 is wirelessly sent to the audio broadcasting receivers 6 and 7, where the alarms and warnings are sent from the speakers 8 and 9 by voice and siren, and other disasters and accidents. Emergency information related to is broadcast.

  The service area related to disaster prevention of the disaster prevention radio base stations 4 and 5 is a portion surrounded by a broken line 10, and the information from the disaster prevention center 2 can be known at the bases 11, 12, 13, and 14 therein. .

  The other service area 15 is managed by the disaster prevention center 16, and information from the disaster prevention center 16 is sent to the disaster prevention radio base stations 18 and 19 via the disaster prevention control station 17. Further, the disaster prevention radio base stations 18 and 19 are wirelessly transmitted to the audio broadcasting receivers 20 and 21, and are audio broadcast from the respective speakers 22 and 23 into the service area 15.

Information on the disaster prevention center 16 can be heard at the bases 24, 25 and 26.
JP 2001-36645 A

  When the disaster prevention center grasps disaster information, it is often grasped by a report using a communication means such as a public line or a mobile phone system. However, in the conventional method, a large-scale network such as a general public line or a mobile phone system is used. It is easy to get in touch with the disaster prevention center because the traffic is abnormally high at the time of a disaster and can not be used, or when a disaster occurs somewhere in the network due to a disaster There was a problem that was not.

  Furthermore, in the conventional method, there is a problem that information cannot be communicated to the area different from the disaster prevention radio base station under the control station for disaster prevention using the disaster prevention radio system even if the disaster area is nearby. It was.

  This is shown in FIG. It is assumed that the base 12 and the base 24 are damaged as a disaster has occurred. At this time, if the network 1 is usable, the base 12 can notify the disaster prevention center 2 of the disaster situation. As a result, it is possible to notify emergency information in the service area 10 from the disaster prevention center 2 and support relief activities using the nearby bases 11 and 13.

  However, if there is a major disaster, the network 1 may be used as a means of information transmission because the traffic may be abnormally high or a line failure may occur somewhere. Not exclusively.

  Next, in the case of the base 24 damaged in the service area 15, when the network 1 becomes difficult to use due to traffic abnormality or disaster, it is difficult to inform the disaster prevention center 16 of the damage situation. Furthermore, it is not easy to obtain information from a nearby base 14 under the control of the disaster prevention center 2 or to ask for support from the nearby base 14.

  In addition, the conventional method mainly focused on voice communication using outdoor speakers, so how to evacuate not only local residents but also people who came from outside the area, even if they heard this notification. There was a problem that it was difficult to understand information about where to go and where to get relief supplies.

  The present invention solves the problems of the conventional large-scale disaster prevention radio system, and with the simplest configuration, it not only informs disaster victims and local residents of necessary information but also understands emergency road guidance. It is an object to provide an easy means to do.

  In order to solve the above-mentioned problems, the present invention provides an electronic guide plate for displaying map information at each site, and each electronic guide plate has transmission / reception means connected to operation means (for example, an emergency push button switch). In addition to notifying the surrounding bases of the situation of their bases, information obtained from the surrounding bases is displayed on the map information on the electronic information board. When a disaster occurs, information is communicated between the bases of each other, and the results are displayed on a map to notify the victims and local residents whether each base is functioning.

  A base is a point where information for disaster prevention can be transmitted and received, but the most different point of the present invention from a conventional disaster prevention system and emergency information transmission system is that it does not go through a large-scale network or a disaster prevention center. By communicating directly between nearby bases using radio, disaster prevention and relief information can be sent and received and notified to local residents. If a specific frequency, for example, the same frequency is used between the bases as the wireless communication, a plurality of bases within a range where radio signals can reach can receive information from the bases almost simultaneously. At this time, as a method for preventing interference, various methods such as changing the timing and period of transmitting information from the reception status of radio waves at each base can be adopted.

  In this case, there are electronic guide boards that only display information sent from other electronic guide boards at some bases, and conversely, other bases use transmitters connected to operation means. The case of a function that only transmits information about its own site is also included in the scope of the present invention.

  The present invention is characterized in that information can be transmitted and received between bases, but not only this, but also means for communicating information with the disaster prevention center can be added. In this case, it is possible to receive radio waves sent from the Disaster Prevention Center, display them on the information board, and inform the surrounding people by voice, etc. You can be informed.

  Furthermore, the present invention has a battery or human-powered charging function so that an electronic guide board, a transceiver, etc. can be used even during a short-term or long-term power failure.

Specifically, in the first aspect of the present invention, one of the following is installed at each base.
[Type A base] Map information display means, wireless transmission / reception means for communication between bases, and transmission / reception electronic guide plate [operation base of type B] map information display means and wireless reception means for communication between bases An emergency information transmitting means comprising a reception-only electronic guide board [type C base] operating means and a wireless transmission means for communication between bases. The types of bases that can be used in combination in this system are as follows. is there.
(1) A plurality of type A sites (2) A plurality of type A sites and one or more type B sites (3) A plurality of type A sites and one or more type C sites (4) A plurality of sites Type B sites and multiple type C sites (5) One or more type A sites, one or more type B sites and one or more type C sites When the operating means is operated, according to the operation content, the status of the base where the transmission / reception electronic guide plate is placed is wirelessly transmitted and notified to the transmission / reception electronic guide plate or the reception-only electronic guide plate of another base. At the same time, the map information display means displays the status of each base sent from another electronic transmission / reception board or other emergency information transmission means.

  In the reception-only electronic guide board at the type B base, the information of each base transmitted from another electronic guide board for transmission / reception or other emergency information transmission means is displayed by the map information display means.

  Since the type C site does not have an electronic guide plate, only the emergency information at the site is transmitted using the inter-site communication wireless transmission unit based on the operation information by the operation unit.

  Further, the second aspect of the present invention is the above-mentioned first aspect of the present invention, further comprising means for wirelessly communicating with any or all of the above bases with the disaster prevention center, and at least information from the disaster prevention center. A means for outputting by voice or an operation means for sending information to the disaster prevention center is provided.

  In addition, according to a third aspect of the present invention, in the first or second aspect of the present invention, at each base, a first power generation unit that generates power by means different from human power, a second power generation unit that generates power manually, A battery for supplying and charging power generated by one or both of the first power generation means and the second power generation means is provided, and the power is supplied to the first power generation means, the second power generation means, or It is characterized by using at least one of the batteries.

  In the event of a disaster, the electronic guidance system of the present invention can be operated simply by operating the operation means provided at each base, such as information on convenience stores and other stores, or information on gas stations, hospital function information, etc. By communicating with each other and displaying the status of each site on the map of the electronic information board, the information required for the victims and local residents is provided. As a result, disaster victims and local residents can easily see on the map where they can get the necessary relief supplies by looking at the electronic information board.

  In addition, not only hospitals but also information on disasters such as major buildings and bridges are displayed on the map, so that non-local people can know where and what route to evacuate. In other words, the disaster prevention function is greatly improved by providing information on evacuation routes to the victims and guiding them safely.

  Here, if there is an operation means such as an emergency push button switch indicating whether or not the site is damaged or a multi-function switch that handles quantity information of relief supplies handled at the site, Not only is it easy to make emergency calls at the time of the disaster, but it is also very functional when carrying out relief activities.

  The electronic guidance system of the present invention is provided with an electronic guide plate that can be transmitted and received at each site and directly transmits and receives between each site. Therefore, the electronic guidance system has the simplest configuration and is unlikely to fail. In addition, even if a failure occurs in part, there are no other spillover problems. In addition, the information is limited to short information such as whether or not each base is functioning or the quantity of relief supplies, so traffic is not affected.

  In the present invention, due to the nature of radio wave propagation, information can be transmitted to the surroundings centered on the information transmission source, and even at a short distance, transmission may not be possible because the area is different. Hateful.

  In addition, when an information communication function with the disaster prevention center is further added to the electronic information board of the present invention, it is possible to receive radio waves sent from the disaster prevention center and notify the surrounding people by voice or the like. Easy guidance is possible. In this case, since the positional relationship with the speaker is close to the electronic guide plate, there is no problem that it cannot be sufficiently heard due to ambient noise or sound reflection. In addition, if the information from the disaster prevention center is information for display, displaying it on the display board is effective in transmitting information that is difficult to hear by voice and in contacting a hearing impaired person or the like.

  In the present invention, the disaster prevention center can be informed of the situation of the base. In the case of the present invention, since the base communicates with the disaster prevention center by radio, it is not easily affected by traffic or line failure that occurs in a large-scale network.

  The electronic guide plate of the present invention is provided with a power failure countermeasure and can be operated by a battery in the event of a power failure. In addition, in the case of a power failure that lasts for a long time, it has a charging function by human power. Can also be used.

[First Embodiment]
FIG. 1 is a diagram showing a first embodiment of the present invention. In the event of a disaster such as an earthquake, a convenience store can be an important base for supplying relief supplies. Reference numerals 27, 28, 29, 30, and 31 represent disaster prevention bases such as convenience stores, and information can be transmitted between these bases using the disaster prevention electronic guidance system according to the present invention. (Of course, 27 to 31 are not limited to convenience stores, and may be any place that can be a base for disaster prevention activities such as general stores and gas stations, as well as hospitals and schools.)
Reference numerals 32, 33, 34, and 35 are display boards for providing electronic guidance, and surrounding bases are displayed on a map. The contents sent from other bases are displayed on the map of these display boards.

  Reference numerals 36, 37, and 38 denote wireless transmission / reception means, reference numeral 39 denotes wireless reception means, and reference numeral 40 denotes wireless transmission means, which enables wireless communication between the respective bases even during a disaster.

  Reference numerals 41, 42, 43, and 44 denote operation means. By operating these operation means, it is possible to notify the other bases of the status of their own base.

  In this figure, 34, 38 and 43 constitute the same electronic guide plate for transmission and reception as the other 32, 36, 41 and 33, 37 and 42. For example, the base 29 can transmit and receive wirelessly in the service area 45 including the surrounding bases 27, 28, 30, and 31 by using a transmission / reception electronic guide plate composed of 34, 38, and 43. The same applies to the other bases 27, 28, and 31 where the transmission / reception electronic guide plates are provided. Therefore, in this system, information emitted from a certain base is transmitted from that base to the surrounding bases as long as radio waves can propagate.

  The base 30 has a reception-only electronic guide plate composed of a display plate 35 and wireless reception means 39. If there is a reception-only electronic information board, you can know the situation of the surrounding bases. In this case, if you know information about which bases around you have relief supplies or information about which bases are affected by the disaster, you can make a great use in disaster prevention activities.

  The base 31 includes an emergency information transmission unit including a wireless transmission unit 40 and an operation unit 44. If there is an emergency information transmission means, it is possible to transmit information as to whether or not the base is damaged, and it is possible to communicate whether or not relief is possible and whether or not there is relief supplies.

  In the present invention, where there is an electronic guide plate for transmission / reception or an electronic guide plate for reception, the status of each base is displayed on the map at any base. Therefore, not only the local residents but also disaster victims from outside the region, information such as which bases have the necessary relief supplies or which bases are damaged and dangerous Can be easily obtained.

[Second Embodiment]
FIG. 2 is a diagram showing a second embodiment of the present invention. In FIG. 2, information of the disaster prevention center 2 is wirelessly transmitted from the disaster prevention radio base stations 4 and 5 via the disaster prevention control station 3. This information is received by the audio broadcasting receiver 46 and is audio broadcast by the speaker 47. This part is the same as that of the prior art, but this system is not only that, it enables wireless communication with the disaster prevention center 2 without going through the large-scale network 1, and the information obtained by the disaster prevention center 2 It is designed to notify the base.

  In the system of FIG. 2, there are 48 transmission / reception electronic guide plates comprising a display board 49, wireless transmission / reception means 50, and operation means 51 at 48 bases, and a display board 53, wireless transmission / reception means 54, operation at 52 bases. There is a transmission / reception electronic guide plate comprising means 55. At 56 locations, there is a reception-only electronic guide plate comprising a display plate 57 and a wireless reception means 58. There are 59 emergency information transmission means including a wireless transmission means 60 and an operation means 61 at 59 sites.

  In the second embodiment, the status of the bases 48, 52 and 59 is input from the operation means 51, 55 and 61, respectively, and the radio transmission / reception means 50 and 54 and the radio transmission means 60 are used to input the disaster prevention radio base. It is sent to the disaster prevention center 2 through the stations 4 and 5 and the disaster prevention control station 3.

  Further, the radio transmitting / receiving means 50 and 54 and the radio receiving means 58 at the bases 48, 52 and 56 are not only capable of receiving information of other bases, but also the disaster prevention center 2 transmitted from the disaster prevention radio base station 4 or 5. Can also be received, and information can be transmitted by voice from the speakers 62, 63, 64 to the immediate vicinity of the base.

  In the second embodiment shown in FIG. 2, for example, at the base 52, the information from the disaster prevention center 2 is not only heard from the speaker 47 connected to the audio broadcasting receiver 46, but also from the speaker 63. I can hear the voice. Since the sound from the speaker 47 is broadcasted at a large volume far away, it may be difficult to hear because there is an echo or the like. However, since the sound of the speaker 63 spreads only at a close distance, there is no problem of echo and the display board Can tell the person watching 53. In this case, if the sound of the speaker 47 and the sound of the speaker 63 interfere and are difficult to hear, there is no problem if the volume of the sound of the speaker 63 is adjusted appropriately.

  If the information sent from the disaster prevention radio base stations 4 and 5 is text information or image information, it is taken in and displayed on the display board together with the map information. In this way, it is possible to convey information in an easy-to-understand manner on the map information to the victims who are looking at the display board.

  As described above, the base 52 can obtain not only the situation of the surrounding bases 48, 56 and 59 but also information from the disaster prevention center 2. From this, it is considered that if the display board 53 can be used for the victims and local residents near the base 52, it is very useful for disaster prevention, such as obtaining rescue supplies and grasping the evacuation route.

[Configuration example of electronic guide plate for transmission and reception]
FIG. 3 is a diagram illustrating a configuration example of the transmission / reception electronic guide plate according to the second embodiment.

The wireless transmission / reception means 65 corresponds to 50 and 54 in FIG. 2, and is used for wireless communication via a disaster prevention center and a disaster prevention radio base station, and a radio transceiver 66 for communication between bases for wireless communication with other bases. It consists of a wireless transceiver 67 for communication between disaster prevention centers. (In the example of FIG. 3, as the wireless transmission / reception means 50 and 54 used in the second embodiment [FIG. 2], a wireless transmission / reception unit 66 for communication between bases and a wireless transmission / reception unit 67 for communication between disaster prevention centers is used. Although used, the wireless transmitter / receiver means 36, 37, 38 used in the first embodiment (FIG. 1) need only be the wireless transmitter / receiver 66 for inter-site communication.
Information from surrounding bases received by the base transceiver wireless transmitter / receiver 66 via the antenna 68 is displayed on the map display unit 70 by the display control unit 69. Also, the information from the disaster prevention center received by the radio transmitter / receiver 67 for communication between disaster prevention centers is output as sound from the speaker 71 if it is voice information, and if it is information for display, the map display unit 70 is displayed by the display control unit 69. Displayed above. As a means for displaying information from the disaster prevention center, a dedicated display means may be provided and displayed there, but it is also possible to display on the map display unit 70 in this way. Can also implement the present invention.

  Further, when the operation means 72 is operated, the information is transmitted from the inter-site communication radio transceiver 66 to the surrounding bases, and from the inter-disaster center communication radio transceiver 67 to the disaster prevention radio base station. . Therefore, at the base where the electronic guide board for transmission / reception is provided, the situation of the base can be notified not only to the surrounding bases but also to the disaster prevention center. In this case as well, dedicated operation means may be provided to transmit information to the disaster prevention center, but the contents of the operation means 72 for inter-base communication may be sent to the disaster prevention center as they are. Either case can be used as an embodiment of the present invention.

  In the event of a disaster, a 100 volt (V) AC power supply is not always stable. In the example shown in FIG. 3, not only the power is supplied from 100 VAC to the wireless transmission / reception means 65, the display control unit 69, and the map display unit 70 via the power supply unit 73 and the diode 74, but the output of the power supply unit 73 is connected to the charger 75. The battery 76 is charged via the power supply, and power is supplied from the battery 76 to the wireless transmission / reception means 65, the display control unit 69, and the map display unit 70 via the diode 77 at the time of a power failure.

  Further, as a countermeasure against a power outage for a long time, a manual charger 78 is provided. By manually turning the handle 79 of the charger, the battery 76 is charged and the electronic guide plate for transmission and reception is operated. It is possible.

  In the example of FIG. 3, the manual charger 78 that is turned by hand is used. However, the manual charger 78 is not limited to the type that is turned by hand. Further, the battery 76 may be generated by using natural energy such as sunlight or wind power and the electric energy is charged. When using natural energy, it will be a measure against a certain power outage, but it may not always be available at night or in a windless state.

[Configuration example of reception-only electronic guide board]
FIG. 4 is a diagram illustrating a configuration example of the reception-only electronic guide plate according to the second embodiment.

The radio receiving means 80 corresponds to 58 in FIG. 2, and the radio receiver 81 for inter-site communication for radio communication with other bases, and the disaster prevention center for radio communication via the disaster prevention center and the disaster prevention radio base station. It consists of a wireless receiver 82 for intercommunication. (In the example of FIG. 4, as the wireless receiving means 58 used in the second embodiment [FIG. 2], a wireless receiver for communication between bases 81 and a wireless receiver for communication between disaster prevention centers 82 is used. However, as the wireless receiving means 39 used in the first embodiment [FIG. 1], only the inter-site communication wireless receiver 81 may be used.)
The difference between the example shown in FIG. 4 and the example shown in FIG. 3 is that the wireless transmission / reception unit 65 is replaced with the wireless reception unit 80 and dedicated to reception, and the other functions are the same. Depending on the site, it may function simply by receiving information from other sites and information from the Disaster Prevention Center and communicating it to the surroundings.

  Of course, there is no necessity of a radio receiver for communication between disaster prevention centers for communication with the disaster prevention center, and a radio transceiver for communication between disaster prevention centers may be provided to inform the disaster prevention center of the situation of this base. Such an embodiment of the present invention is also possible.

[Configuration example of emergency information transmission means]
FIG. 5 is a diagram illustrating a configuration example of the emergency information transmitting unit in the second embodiment.

The wireless transmission means 83 corresponds to 60 in FIG. 2, and a wireless transmitter 84 for inter-base communication for wireless communication with other bases, and a disaster prevention center for wireless communication via a disaster prevention center and a disaster prevention radio base station. It consists of a wireless transmitter 85 for inter-communication. (In the example of FIG. 5, as the wireless transmission means 60 used in the second embodiment [FIG. 2], a wireless transmitter for communication between bases 84 and a wireless transmitter for communication between disaster prevention centers 85 is used. However, as the wireless transmission means 40 used in the first embodiment (FIG. 1), only the inter-site communication wireless transmitter 84 may be used.)
The difference between the example shown in FIG. 5 and the example shown in FIG. 3 is that the wireless transmission / reception means 65 is replaced with the wireless transmission means 83 and dedicated to transmission, and the other functions are the same. Some bases may function by simply sending information about their bases to other bases or disaster prevention centers. Of course, there is no necessity for a radio transmitter for communication between disaster prevention centers for communication with the disaster prevention center. A radio transmitter / receiver for communication between disaster prevention centers may be provided to communicate with the disaster prevention centers. Implementation of the invention is also possible.

[Radio wave propagation]
FIG. 6 shows the state of radio wave propagation in the disaster prevention electronic guidance system of the present invention. The radio transceiver for inter-site communication, the radio transmitter for inter-base communication, or the radio receiver for inter-base communication used in the present invention operates at a frequency at which at least one wave can be used in common.

  Reference numeral 86 denotes a radio wave propagation area that can be transmitted to and received from the base 87, and reference numeral 88 denotes a radio wave propagation area that can be sent to and received from the base 89. The base 87 can transmit to and receive from the bases 90, 91, 92, 93, 94 in the radio wave propagation area 86 centered on its own station, while the base 89 is in the radio wave propagation area 88 centered on its own station. The bases 93, 94, 95, 96, and 97 can be transmitted and received.

  If you can use a frequency that can be used in common, you can send and receive to / from each base in the radio wave propagation area centered on your own station. There is no need, and it is possible to communicate information to surrounding bases by broadcast communication in one operation.

[Operation of wireless transceiver for inter-site communication]
Next, the operation of the inter-site communication radio used in the present invention will be described. The operations of the radio transmitter / receiver for communication between disaster prevention centers, the radio receiver for communication between disaster prevention centers, and the radio transmitter for communication between disaster prevention centers are almost within the scope of the prior art and are well-known technologies. The detailed description above is omitted.

  FIG. 7 is a diagram showing an example of an operation flow of the wireless transceiver for inter-site communication according to the present invention. In the initial state, whether or not radio waves in the commonly used frequency band are in use is detected, and the presence of radio waves is detected. If the radio waves are in use, the receiving lamp is turned on (S1, S2), Information reception processing is performed (S3). This reception processing is continued until an end signal is found in the received signal (S4) or until the presence of a radio wave for a predetermined time is not recognized (S5), and an end signal is found or a radio wave for a predetermined time exists. If not, the information reception process is terminated (S6), the receiving lamp is turned off (S7), and the process returns to the initial state.

  In the initial state, when transmission is activated when radio waves are not in use (S1, S8), the transmitting lamp is turned on (S9), and information transmission processing is performed (S10). This transmission process is performed until the preset information to be transmitted is output (S11). When all the information is transmitted, the information transmission process is terminated (S12), the transmitting lamp is turned off (S13), and the initial process is started. Return to state.

[Operation of wireless receiver for inter-site communication]
FIG. 8 is a diagram showing an example of an operation flow of the radio receiver for inter-site communication according to the present invention. In the initial state, whether or not radio waves in the commonly used frequency band are in use is detected, and the presence of radio waves is detected. If the radio waves are in use, the reception lamp is turned on to receive information. (S20 to S22). The following follows the same flow as the reception in FIG.

[Operation of wireless transmitter for inter-site communication]
FIG. 9 is a diagram showing an example of an operation flow of the wireless transmitter for inter-site communication according to the present invention. In the initial state, whether or not radio waves in the commonly used frequency band are in use is detected, and the presence of radio waves is detected. Processing is performed (S30 to S33). The following follows the same flow as the transmission in FIG.

[Configuration example of operation means]
Next, a configuration example of the operation means used in the present invention will be described. The wireless device can transmit the information signal by inputting the information signal to be transmitted after turning on the transmission activation signal.

  The example of the operation means shown in FIG. 10 temporarily stores the transmission activation switch 98 for generating a transmission activation signal, the character information input keyboard 99, and the output of the character information input keyboard 99, and is output by transmission activation. It consists of a memory 100 for storing transmission information. In the case of the operation means of FIG. 10, various information such as the types and quantities of a plurality of relief supplies and whether the supply is sufficient or not can be transmitted by the character information input key.

  For example, in a store such as a convenience store, when this operation means is used for the electronic information board for transmission / reception and emergency information transmission means of the present invention, the store clerk in advance relates to relief supplies used in the event of a disaster. If the information is entered, when a disaster actually occurs, the necessary information can be transmitted simply by turning on the transmission start switch.

  The example of the operation means shown in FIG. 11 includes only a transmission activation switch 101 and a switch 102 that gives information only on whether or not the site is usable. Such an operation means is used when it is important to determine whether or not the site can be used, such as a bridge over a river. In the case of the operation means shown in FIG. 11, for example, if the switch 102 is turned on if it can be used and the transmission activation switch 101 is started, the fact that the base is usable is transmitted to the surrounding bases. The This kind of operation means is very easy to operate, and can be operated by local community associations or ordinary people.

  FIG. 12 shows an example of operation means that makes the operation means of FIG. 11 easier to understand. If the base is usable, the “use” switch 108 is set. The switch 111 “unusable” may be turned on. In FIG. 12, it is assumed that the transmission activation signal is “1 state” indicating “transmission”, and the information signal is “1 state” and the base is “available”.

  For example, when the “usable” switch 108 is turned on, the voltage of the capacitor 112 is instantaneously discharged and then charged according to the time constant RC with the resistor 107. During this time, the output of the comparator 106 is in the “0 state”. Become. On the other hand, since the “unusable” switch 111 is not operated during this period, the voltage of the capacitor 113 remains at a high value of + V through the resistor 109 and the output of the comparator 110 remains in “1 state”. It is.

  As described above, when the output of the comparator 106 is “0 state” and the output of the comparator 110 is “1 state”, the output of the exclusive OR circuit 105 is “1 state”, and from a short time constant rC. The transmission is activated through the time constant circuit of the resistor 104 and the capacitor 114 and the comparator 103. At this time, the information signal is “1 state” and information indicating that the base is “available” is transmitted. Here, the time constant circuit of the resistor 104 and the capacitor 114 is a circuit that prevents erroneous operation of the switches 108 and 111. For example, when two switches are pressed at the same time, the output of the exclusive OR circuit 105 with a slight time difference. Even if a pulse like a thin whiskers is generated, it is a circuit that removes it and protects it from being transmitted.

[Example of signal format for inter-base communication]
FIG. 13 is a diagram illustrating an example of a signal format when performing communication between bases according to the present invention.

  Example 1 shown in FIG. 13A is an example of a signal format transmitted from a store such as a convenience store. Synchronization is established on the receiving side by a bit synchronization signal and a frame synchronization signal, and then the transmission base is The identification information, information indicating whether or not the site is functioning, and the type and quantity of relief supplies follow, and finally an end signal is sent. The wireless device used in the communication between bases receives this end signal or ends the reception process when no radio wave comes for a certain period of time.

  Example 2 shown in FIG. 13B is an example of a signal format transmitted from a hospital. The difference from Example 1 is that the type of treatment and the number of empty bets are transmitted instead of the type and quantity of relief supplies. Is done.

  Example 3 shown in FIG. 13C is an example of the simplest signal format. For example, only information regarding whether or not a bridge, a building, or a toilet is functioning (usable or not) is transmitted. Even simple information can be important to disaster victims.

[Example of map display]
FIG. 14 is a diagram showing a display example of the map display unit of the guide board of the present invention. In this example, there are A Hospital, B Hospital, A Bridge, B Bridge, C Bridge, A Convenience Store, B Convenience Store, and C Convenience Store, and this information board is located in the C Convenience Store. And It is possible to use both Hospital A and Hospital B, but if Bridge B is broken and there are injuries in the convenience store, go to Hospital A through Bridge A, or go to Hospital B through Bridge C Is a shortcut. In addition, it can be seen that the B convenience store has collapsed and the necessary supplies cannot be obtained even if the B convenience store is asked for what is lacking in the C convenience store. Furthermore, at the convenience store A, although there are water and emergency foods A and B, it can be seen that the clothing C is insufficient for the demand by about 20 people.

  In this way, the disaster prevention electronic guidance system of the present invention displays the status of each base on a map, so that information on relief supplies, information on evacuation routes, etc. can be easily obtained for victims and local residents. In addition to providing effective disaster prevention information to people who are not familiar with the area.

[Configuration example of control device]
In the example of the transmission / reception electronic guide plate shown in FIG. 3, the operation information by the operation means 72 is wirelessly transmitted to other bases by the wireless transmission / reception means 65, and the information received by the wireless transmission / reception means 65 from other bases is displayed. The control unit 69 is configured to display on the map display unit 70.

  Control of the display control unit 69 and the wireless transmission / reception means 65 (the same applies to the wireless reception means 80 of FIG. 4 and the wireless transmission means 83 of FIG. 5) and the like in these electronic guide plates for transmission / reception, for example, as shown in FIG. This process can be realized by a computer having a simple configuration.

  The control device 200 includes a CPU 201, a display control interface 202 for controlling the display control unit 69, a communication control interface 203 for controlling the wireless transmission / reception means 65, and an operation information input for inputting operation information from the operation means. An interface 204 and a storage device 210 such as a memory or a magnetic disk device are provided.

  The storage device 210 stores a control program 211 to be executed by the CPU 201, a reception buffer 212 in which data received through the communication control interface 203 is stored, and data to be transmitted through the communication control interface 203. A transmission buffer 213 to be stored is provided.

  The storage device 210 has a map display information storage unit 214 that stores map display information prepared for each base in advance. The map display information stored here is map image information as shown in the display example of FIG. 15, for example.

  In addition, the storage device 210 includes a local site information storage unit 215 for storing local site information and a local site information storage unit 216 for storing information on other bases within the reach of the radio signal. The own site information storage unit 215 includes site identification information for uniquely identifying each site, site name, site type, information on whether or not the site is functioning, and other information in case of emergency depending on the site. Information to be transmitted to the base is stored. For example, if the base is a convenience store, the data of the type and quantity of relief supplies input in advance, and if the base is a hospital, for example, the data of the type of treatment and the number of empty bets are included. Other information to be transmitted can be stored in advance, and the information can be updated at any time.

  For example, when a plurality of switches corresponding to the type of information to be transmitted are prepared as operation means, the transmission information is stored separately for each switch in the local site information storage unit 215, and the pressed switch It is also possible to select transmission information by transmitting the information to other bases or disaster prevention centers.

  In the other base information storage unit 216, for each base, base identification information, base name, base type, information on whether or not the base is functioning, and information received from the base are received. Information on the position to be displayed (for example, coordinate information in the display screen shown in FIG. 14), received information such as the type and quantity of relief supplies received from other bases, the type of treatment contents, and the number of empty bets is stored. .

  Further, when communication information from the disaster prevention center is stored in the reception buffer 212 instead of communication information from other bases, the information is displayed on a screen different from the display screen shown in FIG. It is displayed on the display screen shown in FIG.

  The above-described input / output control of information is realized by the CPU 201 executing the control program 211. The specific processing flowchart of the control program 211 and other processing contents are clear from the above description and are designed. Since this is a matter of interest, further detailed explanation is omitted here.
