Description

  The present invention provides quick and reliable notification of various disasters that can occur locally and locally, such as heavy rain, local floods, fires, earthquakes, tsunamis, and landslides. The present invention relates to a disaster notification system for preventing damage and spreading damage.

  Japan has complex topography and weather conditions, and is prone to local disasters in small areas. For example, a local earthquake may occur due to a very complicated active fault. Local earthquakes can cause disasters such as local landslides and landslides. A tsunami may also strike a specific area on the coast.

  In addition, having a complex mountainous terrain can cause localized torrential rain. Local torrential rains may cause river flooding, landslides, or debris flows. In particular, local torrential rains called so-called guerrilla heavy rains frequently occur in various places, possibly due to the recent global warming phenomenon.

  In addition, it is not limited to natural disasters, but fires may occur in certain areas. Natural fires such as artificial fires and wildfires occur locally.

  In addition, these disasters that occur locally do not necessarily occur in areas such as urban areas where the population is large and various infrastructures are established. It often occurs in areas where the population is small or the development of various infrastructures is delayed, such as in rural areas and rural areas. When such a local disaster occurs in an area with a small population, the occurrence of the disaster may not be noticed due to the small population. Another aspect is that it is difficult to notice the occurrence of disasters due to delays in the development of various infrastructures. Of course, even if you notice the occurrence of a disaster due to the small population and delays in the development of various infrastructures, it is difficult to inform the local residents and people in the area of the occurrence of the disaster. ing.

  Of course, even in the case of local disasters that occur in highly populated areas such as urban areas, depending on the type and location of the disaster, it may be late to notice the occurrence of the disaster, or the disaster notification may be delayed. Can also occur.

  In this way, being late in noticing the occurrence of a local disaster or not being able to report or delaying a disaster will cause damage from the disaster or increase the damage. . For example, if it becomes late to notice the occurrence of torrential rain or fire, or if the notification is delayed, residents in the affected area or people who happen to be involved in the disaster may be injured or killed. There can be.

  The characteristics of Japan are (1) the occurrence of such local disasters due to the complexity of topography and weather conditions, (2) not only the population is concentrated only in urban areas, but also various medium-scale, Small towns and villages are scattered in many areas. Combined with these two characteristics, the occurrence of a local disaster and the occurrence of damage based on the local disaster are a problem.

  When such a disaster occurs, a technique has been proposed in which homes are connected to each other via a network and notification is quickly made (see, for example, Patent Document 1). Or the technique of alert | reporting a disaster appropriately to an alerting | reporting subject after the occurrence of a disaster is recognized is proposed (for example, refer patent document 2).

JP 2010-134636 A JP 2010-152509 A

  Patent Document 1 discloses that the emergency information management device 1 installed in a plurality of houses constituting the neighborhood information notification system 100 detects this occurrence at other user's homes within the effective communication range of the wireless communication means 12. Send information about disasters. The emergency information management device 1 at the user's home that has received such information transmits a system for transmitting the emergency information to other homes that transmits this information to other user homes within the effective communication range of its own wireless communication means 12. Disclose.

  When the emergency information management apparatus installed in each house detects the occurrence of a disaster, the technology of Patent Literature 1 uses the wireless communication to transmit the occurrence of the disaster in a chain manner to other houses. As a result, each of the houses in the area where the disaster occurred can recognize the occurrence of the disaster.

  However, the technique of Patent Document 1 has the following problems.

  (Problem 1) The mechanism for detecting the occurrence of a disaster is insufficient. When a disaster occurrence is performed by an administrative facility that conducts disaster monitoring, it is extremely difficult to recognize the occurrence of a disaster that is beyond the reach of the administrative facility. Or there is a problem that it takes time to recognize the occurrence of a disaster.

  (Problem 2) In addition, there are many areas where the centralized processing system is used in which the administrative facility first performs notification after the disaster monitoring and the recognition of the disaster occurrence. In this case, it is unavoidable that the recognition of the disaster will be delayed (in the case of a disaster occurring in a local location that cannot be seen from the administrative facility, or outside the operating hours of the administrative organization), and the notification will be delayed. There is a problem.

  (Problem 3) Alternatively, when the occurrence of a disaster is detected by an automatic device, it is necessary to install a different automatic detection device for each type of disaster. In addition, as mentioned above, disasters are often very localized in recent years, such as the occurrence of very localized guerrilla heavy rain. In this case, it is necessary to install a large number of automatic detection devices, and in combination with automatic detection devices that differ depending on the type of disaster, the maintenance cost of the detection device for disaster occurrence becomes high and cannot be covered by the budget of the government etc. There is also a problem.

  (Problem 4) Further, the technique of Patent Document 1 is a communication device installed in a house, and can only notify the next house of the occurrence of a disaster in a chained manner. For this reason, for example, there is a problem that even if a family member is left unattended, it is useless or cannot cope with a disaster. Also, landslides and torrential rains often cause damage outside the house, and it is necessary to notify people outside the house or building. However, this is not possible with the technique of Patent Document 1.

  (Problem 5) In relation to Problem 4, each house needs to be equipped with a communication device. Similar to Problem 3, there is a problem of determining who bears the cost of installing these communication devices in each house. When the government pays, there is a problem that cannot be covered by the government budget.

  Patent Document 2 receives an emergency disaster bulletin and notifies the person to be notified of information included in the received emergency disaster bulletin and / or information calculated based on the received emergency disaster bulletin. For the general question that is the device 1 and is not directly related to the content of the notification, a question answer request means for requesting an answer to the device operator and a notification that automatically selects and sets the content of the notification based on the response of the device operator An emergency disaster information notification device including an automatic content selection setting unit is disclosed.

  Patent Document 2 discloses a system that notifies necessary disaster information based on the received emergency disaster bulletin. In other words, it is assumed that the emergency disaster bulletin is obtained first. However, in the case of earthquakes and tsunamis in a wide area, extensive heavy rain and heavy snowfall, etc., it is possible for an administrative organization or a contracted organization from the government to first recognize the occurrence of this disaster. However, local agencies such as local heavy rains and fires in areas where the density of infrastructure such as population and government agencies is low in local areas are the first to be recognized by government agencies or government agencies. It is very difficult. Of course, this also applies to urban areas as long as they are local disasters.

  That is, Patent Document 2 also has (Problem 1) to (Problem 5) like Patent Document 1.

  As described above, the disaster notification system of the prior art has problems 1 to 5. By simply organizing, <Purpose 1> Local disaster occurrence can be grasped in real time at all times, <Purpose 2> Real-time and constant disaster occurrence can be minimized, and the addition of extra dedicated devices is minimized. Effective for people inside houses, buildings, etc., and people on the go (including those who happen to stay or pass through the area) Therefore, there is a need for a disaster notification system that solves the two problems of informing.

  In view of the problems 1 to 5 described above, the present invention can solve the objects 1 and 2 and is a simple and low-cost system. It is an object of the present invention to provide a disaster notification system capable of notifying the occurrence and caution of disasters in potential areas.

  In order to solve the above-described problems, a disaster notification system of the present invention is a disaster notification system that notifies of the occurrence of a disaster in a predetermined area, and is a communication device that is possessed by one or more owners and can transmit voice. And one or a plurality of broadcasting devices capable of receiving transmission from a communication device and capable of broadcasting audio within a predetermined range, and the owner discovers the occurrence of a disaster indoors and / or outdoors. In this case, disaster information is transmitted by voice through a communication device, and the broadcasting device broadcasts the received disaster information to a predetermined range by voice.

  In the disaster notification system of the present invention, a specific person having a predetermined communication device in a certain area can recognize a disaster and notify the first report only by finding a disaster that has occurred locally. This particular person can recognize disasters at any location, whether they are not in a government agency or a contracting organization, outdoors, at home, or at work. You can also notify the first report.

  For this reason, local disasters that occur in various regions that are difficult to recognize from administrative agencies and contracted organizations can be discovered quickly in real time, and can be immediately connected to notification to the subsequent regions. For this reason, it is possible to reduce the cost required for the detection device and the detected human resources necessary for detection of a local disaster, and local residents can actively discover and notify local disasters that occur locally in the area.

  Moreover, the occurrence and the situation of a local disaster are broadcast in real time from a broadcasting device installed in the area just by transmitting the situation of the disaster by a specific person who has been discovered through a communication device. As a result, the time from discovery to notification is extremely shortened, so that damage caused by local disasters in the area can be minimized. In addition, a specific person discovers a local disaster at a location near the site of the occurrence of a local disaster, such as indoors or outdoors, and then transmits it through a communication device. In other words, it is broadcast from a broadcasting device closer to the occurrence of a local disaster. As a result, it is possible to minimize the damage to the areas and local residents who are most likely to be damaged by the local disaster.

It is a schematic diagram of the disaster notification system in Embodiment 1 of this invention. It is a flowchart which shows the process sequence of the disaster alert system in Embodiment 1 of this invention. It is a schematic diagram of the disaster notification system in Embodiment 2 of this invention.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  (Embodiment 1)

  Embodiment 1 will be described.

(Overview)
First, the general outline of the disaster notification system in the first embodiment will be described. FIG. 1 is a schematic diagram of a disaster notification system according to Embodiment 1 of the present invention. FIG. 1 shows a disaster notification system 1 as an example installed and operated in a certain area. The disaster notification system 1 is installed, for example, in an area where certain villages are concentrated in a certain municipality. Of course, if the area of the municipality is small, the disaster notification system 1 may be installed with any unit of the municipality as one area.

  However, when it is intended to cover the entire municipality as one area with one disaster notification system 1, it may be difficult to cope with a large municipality. For this reason, the disaster notification system 1 should just be installed by making the area where a fixed village concentrates into one cover unit, without sticking to the unit of a municipality.

  The disaster notification system 1 notifies the occurrence of a disaster in a predetermined area. The disaster notification system 1 includes a communication device 3 and a broadcasting device 5. The communication device 3 is possessed by one or a plurality of owners 3 in a predetermined area. The owner 3 may be indoors or outdoors. The owner determined in the predetermined area only needs to have the communication device 3 corresponding to the disaster notification system 1.

  For example, a person appointed in a predetermined area, a town president, a town committee member, or the like may be determined as the owner of the communication device 3 and possess the communication device 3. The communication device 3 can receive a voice and transmit it wirelessly on a communication radio wave. That is, the communication device 3 has a function capable of performing voice communication (voice transmission), such as a mobile phone, a transceiver, and a mobile terminal.

  The owner 2 may discover the occurrence of the disaster 10 while being at least one of indoor and outdoor. Examples of disaster 10 include localized torrential rain such as guerrilla heavy rain, river flooding, tornadoes, gusts and strong winds, fires, landslides, landslides, and traffic accidents. The owner 2 may be outdoors such as at home or work for work or life. Or it may be private or work, and it may be outdoors.

  Thus, when the user is indoors or outdoors, the occurrence of the disaster 10 may be found by chance. You may discover it yourself, or you may be aware of the occurrence of disaster 10 by being taught by others. If the owner 2 can discover or recognize the occurrence of the disaster 10, the owner 2 tells the communication device 3 that the disaster 10 has occurred. That is, the occurrence of the disaster 10 is input to the communication device 3 by voice.

  The communication device 3 can transmit the voice spoken by the owner 2 on a transmission radio wave. That is, the communication device 3 can transmit the voice spoken by the owner 2 as a transmission signal. The transmission destination is one or a plurality of broadcasting devices 5 installed in a range where communication with the communication device 3 is possible. In FIG. 1, two broadcasting devices 5, that is, a broadcasting device 5 </ b> A and a broadcasting device 5 </ b> B are installed. The broadcasting device 5A supports broadcasting to the predetermined range 6A. The broadcast device 5B supports broadcasting to the predetermined range 6B.

  The audio signal transmitted from the communication device 3 reaches the broadcasting device 5A and the broadcasting device 5B. Each of the broadcast device 5A and the broadcast device 5B broadcasts the transmitted audio signal to each of the predetermined ranges 6A and 6B by sound as received disaster information. In the predetermined range 6A, there are one or more buildings 7A, and naturally there are persons inside or outside the building 7A. The broadcasting device 5A can broadcast and notify the disaster information to the person inside the building 7A or the outside person.

  On the other hand, the broadcasting device 5B can broadcast the disaster information by voice in the predetermined range 6B and can notify the occurrence and situation of the disaster 10. At this time, as in the case of the predetermined range 6A, the building 7B exists in the predetermined range 6B. The broadcasting device 5B can notify disaster information by voice to a person or the like inside or outside the building 7B.

  The broadcast devices 5A and 5B perform broadcasting in response to the audio signal transmitted from the communication device 3. That is, the disaster information can be broadcast to the predetermined ranges 6A and 6B almost in real time with respect to the transmission from the communication device 3. Also, the broadcasting devices 5A and 5B can broadcast the audio signal from the communication device 3 as it is (no word conversion or the like). That is, the communication device 3 and the broadcasting devices 5A and 5B are in the same situation as if they are having conversations between the mobile terminal and the transceiver. As a result, the content that the owner 2 who discovers the disaster 10 talks to the communication device 3 is broadcast in real time from the broadcasting device 5A to the predetermined range 6A and from the broadcasting device 5B to the predetermined range 6B.

  A person or the like in each of the predetermined range 6A and the predetermined range 6B can know the occurrence of the disaster 10 and can grasp the danger. For example, in the case where it is considered that the house or workplace where the user is present may be damaged by the disaster 10, the user can evacuate from the place. Or, if you happen to be in the vicinity of the place where the disaster 10 occurs (when walking or moving by car), you can avoid the place and move.

  The disaster 10 often changes rapidly in a small area and in a short time, and it is necessary to take early measures such as evacuation and avoidance. As soon as the owner 2 who is moving within the predetermined area or is within the predetermined area discovers the disaster 10, the owner 2 transmits the voice to the broadcasting devices 5 </ b> A and 5 </ b> B through the communication device 3. People can avoid danger.

  Note that the broadcasting devices 5A and 5B may broadcast the audio from the communication device 3 as it is, or may broadcast after performing certain processing. For example, changing difficult-to-understand expressions or replacing dialects with standard words. Alternatively, it is also preferable that the broadcasting device 5A, 5B automatically add and wrap the time and the address of the place of occurrence to the audio signal transmitted by the owner 2 through the communication device 3. This is because the alerting to people in the predetermined ranges 6A and 6B becomes more accurate by such processing.

(Merit of the disaster notification system of Embodiment 1)
(Discovery height and discovery speed)
When the owner 2 is at least one of indoors and outdoors, the owner 2 can detect the disaster 10 independently even if he / she hears it. In addition, the disaster 10 often occurs in a small area, but the owner 2 finds the disaster 10 when it is in the vicinity of the disaster 10. That is, the discovery rate of the disaster 10 is increased, and the discovered owner 2 can immediately transmit the occurrence of the discovered disaster 10 to the broadcasting device 5 using the communication device 3 possessed.

  In the prior art disaster notification system, a disaster was detected by a designated monitoring organization installed in an administrative organization or a consignment organization, and a disaster broadcast was performed based on a predetermined procedure. For this reason, there was a problem that discovery was delayed or not discovered. Alternatively, the designated monitoring agency does not always patroll various locations in the area, and even if patrolled, it does not necessarily encounter a local disaster. In this respect as well, in the conventional disaster notification system, the discovery of a local disaster is delayed or not made.

  In addition, in the prior art disaster notification system, only the monitoring organization installed in the administrative agency or the commissioned organization (that is, the selected observer) has the authority to detect and notify the occurrence of the disaster. Yes. For this reason, even when a disaster report is received from a general resident, there is a problem that disaster broadcasting cannot be performed unless it is confirmed and a predetermined procedure is followed. As a result, there has been a problem that damage has occurred or has spread to residents in the area where the local disaster has occurred, persons who happen to be there, or persons who have passed or are close to the area.

  On the other hand, as described above, the disaster notification system 1 according to the first embodiment transmits voice to the broadcasting devices 5A and 5B when anyone discovers the disaster 10 as long as the owner 3 owns the communication device 3. it can. For this reason, the number of people who discover the disaster 10 increases without being limited to only a specific person, and naturally the discovery rate and the time from the occurrence of the disaster 10 to the discovery are shortened.

  In addition, the monitoring organization needs to detect the occurrence of the disaster 10 only by a monitor who is waiting in a specific place or a monitor who is patroling. This naturally reduces the discovery rate. On the other hand, the owner 2 exists in various places at random, such as indoors and outdoors. In addition, anyone who is appointed becomes the owner 2 and has the communication device 3. As a result, the owner 2 who owns the communication device 3 always exists in various places. Naturally, the discovery rate of the disaster 10 is improved, and the time from occurrence to discovery is shortened.

  In particular, since the communication device 3 is a small terminal such as a transceiver or a cellular phone, the owner 3 can easily carry the device even when away from home. For this reason, unlike monitoring at a fixed place such as a monitoring agency by the government, the owner 3 can go out to various places (of course, not for disaster detection but for his own business) To). Naturally, it is easier to find the disaster 10 when you are away from home. In this way, the owner 2 can often find the disaster 10 accidentally at the destination where he / she goes out, and the discovery rate is also improved in this respect. Of course, the time from disaster occurrence to discovery is also shortened. The effect increases as the number of owners 3 increases.

(Real-time notification)
In addition, the owner 2 who has discovered the disaster 10 can immediately transmit the fact of the discovery of the disaster 10 and the situation of the disaster 10 by voice using the communication device 3 possessed at hand. When the transmitted audio signal reaches the broadcasting devices 5A and 5B, the broadcasting devices 5A and 5B perform broadcasting as it is (there may be a delay caused by signal processing and specifications).

  That is, the owner 2 can immediately notify if the disaster 10 is found. In the case of the prior art, for example, even if a monitoring person discovers a local disaster, it is possible to connect to a notification for the first time after following a predetermined procedure or operating a predetermined device. Alternatively, even when a disaster detection report is received from a general inhabitant or the like, the monitoring organization confirms the occurrence of the disaster and then enters a notification processing procedure.

  That is, in the prior art, not only the discovery is delayed, but also the time from discovery to notification is often very long.

  On the other hand, as described above, the disaster notification system 1 according to the first embodiment has only to transmit the voice as it is through the communication device 3 possessed when it is discovered, so the time from discovery to notification is almost real time. Of course, the voice transmission from the found owner 2 to the communication device 3 is in real time, and the fact that the communication device 3 can communicate directly with the broadcasting devices 5A and 5B, the owner 2 has transmitted. The sound is broadcast in real time to the predetermined ranges 6A and 6B.

  By combining these procedures, the time from discovery of the disaster 10 to notification is greatly shortened. In other words, while the disaster 10 is discovered, it is possible to prevent the damage from being delayed due to the notification being delayed.

(Advantages of voice transmission while moving)
In addition, the owner 2 can transmit information on the discovered disaster 10 to the broadcasting devices 5A and 5B through the communication device 3 (which can be mobile). For this reason, the owner 2 can transmit disaster information while walking, running, or traveling by car or the like.

  It is often dangerous for the disaster 10 to stay near the site depending on the type of disaster. The fact that the owner 2 can find the disaster 10 is a state in the vicinity of the place where the disaster 10 occurs.

  For example, if the disaster 10 is a river flood or a heavy rain, the range may gradually increase. Even if the disaster 10 is a fire, the range may gradually increase. In this way, the owner 2 who discovers the disaster 10 whose range is gradually expanded, finds the facts of the discovery and the disaster information in a fixed place (such as a broadcasting room having a so-called broadcasting facility. Monitoring institutions are fixed in this way. It is possible to transmit only from a broadcasting room having a broadcasting facility. In this case, as a matter of course, there is a problem that the risk to the found owner 2 increases with the spread of the disaster.

  For example, in the Great East Japan Earthquake that occurred in 2011, there was a tragedy that a person in charge who continued to broadcast a tsunami warning from the broadcast room was involved in the tsunami.

  On the other hand, the disaster notification system 1 according to the first embodiment can transmit voice to the broadcasting device 5 only by talking to the communication device 3 that is movably possessed. That is, the owner 2 who has discovered the disaster 10 can continue to transmit disaster information while evacuating from the disaster.

  In this respect, unlike the prior art, the owner 2 can prevent himself / herself from being damaged by the disaster while continuing to transmit the disaster information. If this happens, naturally, the discovered owner 2 is more motivated to transmit disaster information, and the owner 2 can transmit and notify the disaster 10 occurring in various regions with a higher probability. .

  The owner 2 can transmit the disaster information to the broadcasting device 5 through the communication device 3 when he / she finds the disaster 10 while moving outdoors. Alternatively, even when the user is indoors, when the disaster 10 is found, the disaster information can be transmitted to the broadcasting device 5 through the communication device 3.

  In any case, the owner 2 can transmit disaster information through the communication device 3 while escaping from the disaster damage.

  The owner 2 who is indoors can also transmit information on the disaster 10 he / she finds through the communication device 3, or transmit information on the disaster 10 based on information obtained from another person through the communication device 3. You can also

  Next, the detail of each part is demonstrated.

(Communicator)
The communication device 3 is a device possessed by the owner 2 and capable of transmitting voice on radio waves. It is preferable that the owner 2 can carry it while moving, and a general-purpose device such as a mobile transceiver, a mobile phone, a mobile terminal, and a portable terminal may be used, or a dedicated device may be used.

  It is preferable that the communication device 3 has a standard capable of being transmitted and received in pairs with the broadcasting device 5. This is because the broadcasting device 5 needs not only to broadcast to the predetermined range 6 through a speaker or the like, but also to receive an audio signal transmitted from the communication device 3 and convert it into audio.

  Since the communicator 3 needs to be used by the owner 2 for as long as possible, it is preferable that the communicator 3 is operated by a battery.

  When the owner 2 possesses the communication device 3, when the disaster 10 is found, the owner 2 can transmit it to the broadcasting device 5 and notify the people in the predetermined range 6. For this reason, it is preferable that the owner 2 is a specific person defined in a predetermined area. This is because if the owner 2 is appointed too randomly and indefinitely, problems such as mischief and deterioration in credit quality occur.

  On the other hand, if the number of owners 2 is limited and too small, there is a problem that the discovery rate of the disaster 10 is lowered. For this reason, there are people who have high responsibility and trustworthiness, such as town chairpersons, town caretakers, teachers, etc., local shopkeepers, who are familiar with information on the specified area and who frequently move to the specified area. It is appropriate to be appointed as the owner 2.

(Broadcast equipment)
As described above, the broadcasting device 5 has a transmission / reception standard that is paired with the communication device 3, and further receives the audio transmission from the communication device 3 and broadcasts the audio to the predetermined range 6. For this reason, it is preferable that the broadcasting device 5 has a communication function and an audio broadcasting function. In order to be simply configured, it is appropriate to include a communication device having the same standard as the communication device 3 and a speaker that can be connected to a transmission portion of the communication device and can spread and broadcast audio.

  The broadcast device 5 may broadcast the received audio signal as it is. By carrying out like this, the audio | voice which the owner 2 transmitted when discovering the disaster 10 can be broadcast in real time. Since the content that the owner 2 speaks to the communication device 3 can most represent the danger of the disaster 10, it is preferable to broadcast it as it is.

  Of course, as described above, if there are dialects, words that are difficult to hear, etc., it is also appropriate for the broadcasting device 5 to automatically correct and broadcast. In addition, the broadcast device 5 may automatically explain the location of the location where the disaster 10 transmitted by the owner 2 through the communication device 3 occurs. For example, the broadcasting device 5 may automatically broadcast information such as how far the place where the disaster 10 occurs with respect to the predetermined range 6 to be broadcasted by the broadcasting device 5.

  Further, the photographic part shown in a part of FIG. 1 shows an actual design example of the broadcasting devices 5A and 5B. Each of the broadcasting devices 5A and 5B is installed on at least one of a utility pole, a traffic light, a rooftop of a building, and a dedicated support column. In the photograph of FIG. 1, broadcasting devices 5A and 5B are installed on the utility pole.

  Thus, the installation cost of a broadcasting device can be reduced by installing the broadcasting device 5 in the infrastructure already prepared. Further, by being installed on at least one of a utility pole, a traffic light, a roof of a building, and a dedicated support column, broadcasting from a high position is possible, and the effect of broadcasting in the predetermined range 6 is enhanced.

  In some cases, if there is an infrastructure in which speakers are already installed, a broadcasting device 5 that can broadcast an audio signal from the communication device 3 simply by installing a communication device corresponding to the communication device 3 on this speaker. Is completed. Thus, it becomes possible to reduce the installation cost of the disaster notification system 1 of Embodiment 1 by utilizing existing infrastructure efficiently.

  It is also preferable that the broadcasting device 5 has a specification that receives the audio signal from the communication device 3 and turns on the power of the broadcasting device 5. Of course, the broadcasting device 5 only needs to be able to exhibit the function of broadcasting when the disaster 10 occurs. For this reason, it is not preferable that the power supply is always ON from the viewpoint of power consumption of the broadcasting device 5. Further, when the broadcasting device 5 is operated by a battery, there is a possibility that the battery is insufficient in power supply when broadcasting is actually required.

In order to cope with such environmental problems and unforeseen circumstances, it is also appropriate for the broadcasting device 5 to have a specification for receiving power transmission from the communication device 3 and turning on the power.
As shown in FIG. 1, even when a plurality of broadcasting devices 5A and 5B are provided in a predetermined area, each of the plurality of broadcasting devices 5A and 5B receives a voice transmission from a single communication device 3 and It is also preferable that the power supply is turned on.

  In this way, after the power is turned on, the broadcast device 5 broadcasts the audio transmission from the communication device 3 to the predetermined range 6. At this time, in consideration of the delay in turning on the power, it is also appropriate that the broadcasting device 5 holds a broadcast corresponding to the delay and a memory necessary for this.

(Processing procedure)
Next, a processing procedure will be described with reference to FIG.

  FIG. 2 is a flowchart showing a processing procedure of the disaster notification system according to Embodiment 1 of the present invention. The flowchart of FIG. 2 shows the operation procedure of the disaster notification system 1 installed in a predetermined area as shown in FIG.

  First, in step ST1, the owner 2 owns the communication device 3. The owner 2 possessing the communication device 3 moves outdoors in a predetermined area or stays indoors according to his / her needs. Alternatively, the owner 2 moves in a predetermined area for the purpose of finding the disaster 10 or the like.

  Next, the owner 2 discovers the disaster 10 in step ST2. The disaster 10 is various disasters such as heavy rain and landslides. The owner 2 may find the disaster 10 by his own visual recognition, or may find the disaster 10 by hearing from others.

  If found, the owner 2 sends information on the disaster 10 to the communication device 3 in step ST3. Since the communication device 3 is a transceiver, a portable terminal, or the like, it has a function capable of transmitting an audio signal by transmitting and receiving. Next, in step ST4, the communication device 3 transmits audio to the broadcasting device 5 in the communication range by the communication function of the communication device 3. In audio transmission, transmission according to the standard of the communication device 3 may be performed.

  Next, in step ST5, the broadcasting device 5 that has received the audio signal from the communication device 3 turns on the power. Normally, the power is turned off and the power is turned on for the first time by receiving an audio signal, so that the power consumption of the broadcasting device 5 can be reduced and the battery can be prevented from running out.

  When the power is turned on, in step ST6, the audio signal received by the broadcasting device 5 is output to a speaker included in the broadcasting device 5. The broadcast device 5 has a communication function (communication means) that receives an audio signal from the communication device 3 and an audio broadcast function (broadcast means) such as a speaker that broadcasts audio. When the power is turned on, an audio broadcasting function such as this speaker functions. In this regard, the broadcast device 5 may be configured such that only the communication function is always turned on, and only the broadcast function is turned on only when an audio signal is received.

  Next, in step ST7, the broadcasting device 5 broadcasts the received disaster information as a sound to a predetermined range. The predetermined range to be broadcast is determined by the broadcasting capability of the broadcasting device 5 and may be determined in accordance with the local situation.

  Finally, in step ST8, a predetermined range of people can listen to the broadcast of the broadcast device 5. People who heard the disaster information will try to prevent the disaster damage from spreading by devising it so that the damage from the disaster does not affect themselves or by transmitting it to others.

  As described above, the local residents can quickly inform themselves about the disaster 10 that can occur in the region, without borrowing a large-scale mechanism such as an administrative agency or a commissioned organization, with low cost and infrastructure, and prevent damage from occurring. be able to. In addition, unlike the administrative agency or the commissioned organization, the disaster notification system 1 according to the first embodiment prevents damage caused by various disasters 10 in the region by combining the discovery of the disaster 10 with a small turning and the notification corresponding to the discovery in real time. Can be realized.

  (Embodiment 2)

  Next, a second embodiment will be described. In the second embodiment, a disaster notification system that includes a relay device and expands the range that can be broadcast is disclosed.

  FIG. 3 is a schematic diagram of the disaster notification system according to Embodiment 2 of the present invention. The disaster notification system 11 in the second embodiment includes a relay device 8. The relay device 8 plays a role of broadcasting disaster information transmitted by the owner 2 through the communication device 3 over a wider range.

  The broadcasting device 5A and the broadcasting device 5B are provided in a range in which audio transmission from the communication device 3 possessed by the owner 2 can be received. For this reason, each of the broadcasting device 5A and the broadcasting device 5B can directly receive the voice transmission from the communication device 3. The broadcast apparatus 5A broadcasts the directly received audio signal as audio in the predetermined range 6A. Similarly, the broadcast device 5B broadcasts the directly received audio signal as audio in the predetermined range 6B.

  At this time, the procedure and mechanism for broadcasting the disaster information transmitted from the communication device 3 as sound is as described in the first embodiment.

  On the other hand, even in the case of the disaster 10, the damage may be wide-ranging. For example, even in the case of guerrilla heavy rain, the position is constantly changing, and guerrilla heavy rain may move from one area to another. Of course, river floods and forest fires are the same.

  The communication device 3 that the owner 2 can carry while moving has a merit that it is small and easy to carry while moving, and that a broadcast license and a communication license are unnecessary. However, such a communication device 3 has a small radio wave output and has a limit in the distance that a transmission signal can reach the installed broadcasting device 5.

  However, a certain disaster 10 may affect not only the ranges corresponding to the predetermined ranges 6A and 6B but also the predetermined ranges 6C to 6E. In such a case, it is impossible to broadcast a disaster to all the predetermined ranges 6A to 6E only by voice transmission from the communication device 3 possessed by the owner 2.

  The relay device 8 can solve such a problem. The relay device 8 can transmit the audio signal received from the communication device 3 by performing amplification or the like to the broadcasting device 5C that is more than a certain distance away. This is so-called retransmission. Alternatively, the relay device 8 may relay and transmit the audio signal from one broadcast device 5 to another broadcast device 5. In any case, the relay device 8 can spread the audio signal from the communication device 3 to the broadcasting device 5 in a wider range.

  In FIG. 3, each of the broadcasting device 5C provided in the predetermined range 6C, the broadcasting device 5D provided in the predetermined range 6D, and the broadcasting device 5E provided in the predetermined range 6E performs broadcasting based on the relay signal from the relay device 8. Do. The broadcast procedure is as described in the first embodiment.

  In this way, disaster information can be broadcast and notified to the predetermined ranges 6C to 6E, which could not be covered only by the transmission output of the communication device 3. As a result, a wide range of people can be alerted to disasters.

  Of course, the range that can be broadcast from one communication device 3 is further expanded by installing a plurality of relay devices 8 or connecting the relay devices 8 so that transmission and reception are possible.

  As described above, the disaster notification system 11 according to the second embodiment can notify the occurrence of disaster and the information thereof in a wider range at an early stage and in real time. Of course, as in the embodiment, since the local residents' self-discovery work is notified as it is, a mechanism for preventing damage in the area in the area is constructed. As a result, disaster prevention can be prevented based on various aspects.

  In addition, the communication device 3 and the broadcasting device 5 can use existing inexpensive members, and the infrastructure maintenance cost can be reduced. As a result, local disaster prevention can be promoted by local efforts without waiting for administrative assistance or budgetary measures.

  As described above, the disaster notification system described in the first and second embodiments is an example for explaining the gist of the present invention, and includes modifications and modifications without departing from the gist of the present invention.
