It outputs the phone number string of the mobile phone holder for people who are walking. This telephone number string is stored in the victim information data table 4. Therefore, the victim information data table 4 stores information on the location of the disaster, information on the presence / absence of humans in the location of the disaster, information on mobile phone numbers in the vicinity of the location of the debris flow, together with the date, time, place, etc. It

The moving distance calculation unit 25 reads out and monitors the location information of each disaster victim (name or telephone number information) from the disaster victim information data table 4 at predetermined time intervals and monitors it. Output moving distance information.

The rescue-necessity determination unit 26 searches the travel distance information for the owner of the mobile phone among the victims 5 who should be guided by the evacuation who have not moved even after a lapse of time. Rescue determination section 26
Is a mobile phone owner who has not moved at all, for example, 30 minutes have passed since the movement distance calculation unit 25, but has not moved at all. 28 and the information terminal 29 of the person concerned / manager.

It is presumed that the person who has not moved at all is a person who needs to be rescued, such as a person who has a mobile terminal such as a cell phone and is buried in the debris flow 11, a person who is injured and unable to move, a physically handicapped person, the elderly or a child. To do. When there is an immovable person in the dangerous place, the rescue-requiring determination unit 26 recognizes the rescue-requiring person and outputs the telephone number, name, and location information of the victim 5 to the information providing unit 27.
The government office 28 such as a fire station or a police station sends the victim 5 to the evacuation site 30 by communicating with a mobile communication terminal or the like carried by the person requiring rescue.
Evacuate to, or rescue if you cannot evacuate by yourself.

The human presence / absence determination unit 14 in the dangerous place reads from the disaster victim information data table 4 the presence / absence of a person corresponding to the information of the debris flow occurrence place 11 from the disaster occurrence place identification unit 13, and the victim who needs evacuation The name, telephone number list, and location information are output to the evacuation guidance route map selection unit 32.

The evacuation guidance information output system for the victims 5 is an evacuation guidance data table 31 in which an evacuation guidance route map from each district to the evacuation site 30 is stored in advance, and an evacuation suitable for the location of each victim 5 An evacuation guidance route map selection unit 32 that selects the optimal evacuation guidance route map for the location 30, and an evacuation guidance route determination unit 33 that confirms and determines the safety of the optimal evacuation guidance route.
And an evacuation guidance information notifying device 34 that outputs the optimum evacuation guidance route map to the mobile phone of each victim 5 who has a mobile phone as voice or character information or an image.

In the evacuation guidance data table 31, an evacuation guidance route map from each district to the evacuation site 30 and a map of each district,
In addition, information on the current construction work, information on steep slopes, narrow roads, broken bridges, etc. is stored, and an evacuation guidance route map for roads where many victims can evacuate safely and quickly can be read. The evacuation guidance data table 31 stores a large number of evacuation guidance route maps to predetermined evacuation sites 30 in each district. The evacuation guidance route covers all the roads appearing on the map, and the road leading to the evacuation site 30 is selected. All roads are selected so that if a road is cracked and cut due to a disaster, another road can be selected (searched).

The optimum evacuation guidance route map selection unit 32 retrieves an evacuation guidance route map showing the optimum roads for the victims 5 and automobiles in the disaster location to evacuate to the evacuation site 30. The optimum road for evacuating to the evacuation site 30 is searched (selected) as a selection condition such as that the road is not under construction, is not a steep slope, is not a tunnel, or is not a narrow road. The evacuation guidance route map selection unit 32 selects an optimal evacuation guidance route to the evacuation site 30 based on the location information of each disaster victim 5 and the relationship with the debris flow generation position 11, which is the disaster occurrence site. The safety information of the evacuation site 30 and the safety information of the passages 34 and 36 for evacuating are the current information detected and confirmed by a surveillance camera, an optical fiber sensor, or the like. That is, the optimum evacuation guidance route map is selected from the information without damage (or the road without the information with damage), and the information with damage is not selected. Regarding the evacuation status at the evacuation site 30, the evacuation status of the mobile phone owner can be confirmed by adding the function of the personal authentication system to the mobile phone. Registered as an evacuation measure in the event of a disaster, received a benefit of a contactless data carrier (IC card) in advance as a proof by the data carrier system, and evacuated to the evacuation site 30 A response in which the contactless data carrier was installed in advance in the evacuation site 30 Evacuation can be automatically confirmed by communicating with the vessel. By inputting information such as name, address, and blood type into the non-contact data carrier, it is effective at the time of medical treatment such as accident or injury. Especially, if Silva is registered in the resident list by distinguishing persons with disabilities, the elderly, and the child, Silva will
It is possible to give priority to rescue and evacuate quickly.

The evacuation guidance route map selection unit 32 sequentially reads the evacuation guidance route maps from the evacuation guidance route data table 31 in which a large number of evacuation guidance route maps are stored and stored, and goes to a predetermined evacuation site 30 such as a gymnasium. It automatically searches for and selects the most suitable evacuation guidance route map. The evacuation guidance route map selection unit 32 selects an optimal evacuation guidance route map so that the evacuees can be dispersed so that they can evacuate without congestion. Dispersion of evacuees is obtained by predicting the number of evacuees gathering at each evacuation site 30 after a disaster occurs and the start of evacuation guidance. The optimum evacuation guidance route map is a diagram in which the direction of evacuation is described on the map, for example.

The evacuation guidance route information determination unit 33 collates with the safety information (debris flow occurrence location information) from the disaster detection unit 2 about the optimum evacuation guidance route for each victim output by the evacuation guidance route map selection unit 32. The safety is confirmed and output to the evacuation situation prediction unit 41 and the evacuation guidance information notification device 34.

The evacuation guidance information notifying device 34 is provided for each victim 5
Each time a large number of mobile phone communication cards conforming to the above are stored and notified to each disaster victim 5, the optimum evacuation guidance route map is output to the mobile phone of each disaster victim 5 by voice or image by wireless communication. In this embodiment, each optimum evacuation guidance information is simultaneously output to each disaster victim 5.

There are two types of evacuation guidance route maps guided in this embodiment. The victim 5 who was on the east side of the debris flow 11 is guided to a path that runs through the road 35, crosses the sea by the ship 36, and evacuates to the evacuation site 30B on the opposite bank. On the other hand, the disaster victim 5 who was on the west side of the debris flow 11 is guided to a path to run through the road 37 and evacuate to the evacuation site 30A. The evacuation guidance information notification device 33 is provided for all the victims 5 in the evacuation site 30.
The optimal guidance evacuation route map up to can be displayed on a large display screen or a speaker. This display includes an optical display means and an acoustic display means as guidance displays. The optical display means is, for example, an electronic display board, an LED array display board, a plasma display, a car navigation, or the like. The acoustic display means broadcasts, for example, to notify by a voice from a speaker.

The victims who evacuate by receiving the guide according to the optimal evacuation guidance route map evacuate to the evacuation site 30 according to the guide. This evacuation situation monitoring system outputs the dispersed state in which the evacuation situation is predicted so as to disperse the evacuees according to the situation. For example, the evacuation situation prediction predicts the number of victims 5 who should be visible in the evacuation site 5. Part 41, evacuation status of the victim 5 and evacuation status that outputs the number of people who can see the evacuation site 30
It is composed of a result measuring unit 42 and a comparison circuit 43 which outputs an error number between the number of persons actually seen in the evacuation site 5 and the estimated number of persons.

The evacuation situation predicting unit 41 predicts that the evacuation guide route evacuation based on the distributed guide selected and output by the evacuation guidance route map selecting unit 32 will promptly evacuate to the target number of the disaster victims 5 and a safe position, depending on the evacuation guidance route map selecting unit 32. do. This evacuation prediction is, for example, a prediction that how many people should evacuate to the evacuation site 30 after 30 minutes. Based on this prediction, the evacuation site 30 can prepare for the acceptance of evacuees.

The comparison circuit 43 includes the evacuation guidance route map selection unit 3
The result of evacuation based on the evacuation guidance selected by 2 is the evacuation status
When the difference between the number of victims 5 who have evacuated to the evacuation site 30 output by the result measurement unit 42 and the set predicted number of people is large and the difference is large, the distribution ratio is changed so as to adjust the predicted number of people.

The ideal safe position is the evacuation site 5,
It depends on the content of the disaster, but more and more people will leave the scene of the disaster as soon as possible. It is the purpose of distributed evacuation to leave as many steps as possible from the disaster site in an instant. That is, in order to leave as many steps as possible from the disaster site in an instant, depending on the number of people who should evacuate and the situation of the evacuees so as not to give evacuation information that concentrates on one evacuation route, several evacuation routes should be It is necessary to determine the number of people who can pass through the evacuation route based on the condition such as the width of the road and the presence of stairs so that it will not exceed the number.

As a concrete means of dispersion, the evacuation guidance route map selection unit 32 predicts and classifies the athletic ability of each evacuee, and selects the optimum evacuation guidance route for each classified group. For example, a person who was in an elementary school or a nursing home selects the flat road closest to the evacuation site 30. For those in high school and factories, choose a slightly detoured road. The result of this prediction is a feedback circuit that uses each evacuation route and repeatedly calculates the behavior of the evacuees associated with the evacuation guidance information so that everyone can evacuate to the evacuation site 30 earliest and reflect them in the evacuation guidance path selection unit 32. Is provided.

The progress of evacuation of the disaster victims 5 and the number of the disaster victims 5 who have arrived at the evacuation site can be monitored by measuring the transmitted radio waves when the disaster victims 5 are guided to the evacuation. The evacuation monitoring information is sequentially stored in the disaster information data table 4 as the latest information.

In this way, the disaster evacuation guidance system 1 using the communication means is constructed.

Next, an evacuation guidance method by the evacuation guidance system 1 at the time of disaster using communication means will be described with reference to the flowchart of FIG.

In the evacuation guidance data table 31, a large number of evacuation guidance route maps leading to each evacuation site 30 are stored in advance based on the map of each management target area (S-1). Normally, in communication of a mobile phone or the like, communication is carried out between mobile phones owned by individuals through the communication relay station 1, and a weak radio wave is emitted from the mobile terminal during standby, and the radio wave is received by the communication relay station 1. Therefore, the communication waiting state is set.

Next, the occurrence of a disaster is detected and the presence or absence of people in the disaster area is determined. The various sensors 2 installed in each district generate outputs from the sensors 2 when a disaster occurs. For example, when a disaster such as an earthquake or a volcanic eruption occurs in a certain area, various sensors 2 for disaster detection such as a landslide (debris flow) detector, a water level gauge, and a delevi camera installed in the area are used to detect damage information or Detects and outputs harmless information. The disaster detection information receiving unit 12 receives the occurrence of a disaster from the sensor 2 that has detected the damage information, and outputs it to the victim information data table 4. The victim information data table 4 stores the input time, place, contents of damage (disaster), etc. as disaster information (S-2). An address is assigned to each disaster detection sensor 2, and the disaster occurrence location identification unit 13 identifies the disaster occurrence location from the address of the sensor 2C that detected the debris flow 11 and stores it in the victim information data table 4 (S -3).

When the disaster detection information receiving section 12 automatically detects the occurrence of a disaster, the mobile terminal position detecting section 22 relays radio waves transmitted from a mobile terminal, such as a mobile phone, in the disaster area including the disaster area. It is received via the station 21, and the presence or absence of a person is determined by automatically detecting the owner of the mobile phone from the mobile terminal information (S-4).

When the mobile terminal position detection unit 22 cannot receive the radio wave transmitted from the mobile phone, it is determined that there is no victim, and only the occurrence of the disaster is notified to the government office 28 such as the fire station or the police station, and the evacuation guidance activity is not performed. The process ends without doing (S-5).

When the mobile terminal position detecting unit 22 receives the radio wave transmitted from the mobile phone, the dangerous person presence / absence determining unit 14 determines that there is a victim, and the mobile terminal position detecting unit 22 determines the telephone number from the received radio wave. Automatically output location information. The name / position information determination unit 23 reads the name corresponding to the telephone number from the personal data table 6 of the communication company, and outputs and stores the name, telephone number, location information, time information, etc. in the victim information data table 4 ( S-6).

The rescue required person judging section 26 determines the name of the rescue required person,
The telephone number, the location information, and the presence / absence of a person requiring rescue who cannot move are automatically determined (S-7). The rescue-requiring person determination unit 26 sends list information such as the name, telephone number, and location of the rescue-requiring person to the government office 28 such as a fire station or police station and the information terminal 29 of the related person / manager via the information providing unit 27. Report automatically. Information terminal 29 of related person / administrator operates
It is reflected in management (S-8). The government office 28 such as the fire station or the police station starts the rescue operation for the person requiring rescue (S-9).

On the other hand, when a disaster occurs and there is no person requiring rescue, the evacuation situation prediction unit 41 sends all the victims 5 to the evacuation site 3.
Make predictions for distributed evacuation to quickly evacuate to zero. For example, the evacuation situation prediction unit 41 may change the evacuation site 30 over time.
Predict the number of evacuees evacuated to. The number of evacuees can be predicted by dividing the evacuation roads into multiple places, increasing the number of evacuation sites to multiple places, and selecting the most suitable means such as aging males and females, ages, people with physical disabilities, sick people, and kindergartners to distinguish evacuation roads. It can be selected as appropriate (S-10).

The evacuation guidance route map selection unit 32 uses the dispersed evacuation information from the evacuation situation prediction unit 41, the name information, telephone number information, location information, and sensor 2 of each victim read from the victim information data table 4. The optimum evacuation guidance route is read from the evacuation guidance data table 31 based on the safety information, etc., and is automatically selected for each disaster victim (S-11).

The evacuation guidance information notifying device 34 automatically calls the safe and optimal evacuation guidance route map to each selected victim by calling the mobile phone of each victim 5 by radio wave 38 and distributing dispersed evacuation guidance by voice or image. To do. Distributed evacuation guidance is a method aimed at allowing many victims 5 to evacuate quickly. It is a guide map that considers disperse evacuation of the disaster victims 5 in order to avoid delaying evacuation due to the concentration of the disaster victims 5. In the distributed evacuation, for example, the paths for evacuation of the victims 5 are dispersed into a plurality of paths for the purpose of allowing more victims 5 to evacuate quickly. In the example of distributed evacuation, the victim 5 on the road 34 on the sea side where the debris flow 11 has occurred evacuates to the evacuation site 30B using the ship 35, and the victim 5 on the road 36 side evacuates to the evacuation site 30.
It is a guide distributed in two directions so as to evacuate to A (S
-12).

The evacuation status / results measuring unit 42 is provided at each evacuation site 3
The number of evacuees evacuated to 0 is counted and output to the comparison circuit 43. That is, the mobile terminal position detection unit 22 outputs a telephone number list by receiving radio waves from a mobile telephone carried by the evacuee via the relay station 21 provided near each evacuation site 30, and the telephone number list is output. The evacuation status / result measurement unit 42 counts and outputs the number of evacuees.

The comparison circuit 43 compares the number of evacuees with the predicted number of people output from the evacuation situation prediction unit 41, and if the number of evacuees is significantly smaller than the predicted number of people, increases the number of evacuees guided to the evacuation site 30. Adjusting the number of evacuation roads, etc., and implementing appropriate balancing measures for prompt evacuation. On the contrary, if the number of evacuees is larger than the expected number, the current evacuation method will be continued. That is, the evacuation situation prediction unit 41 compares the movement amount of the evacuees, which changes with the passage of time from the movement distance measurement processing unit 25, with the predicted value at any time by the comparison circuit 43 to monitor and to guide the evacuation so that they match. The content of the dispersed evacuation guided by the path selection unit 32 is adjusted (S-13). These evacuation status information can be obtained from government offices such as fire stations, police stations, facility managers, etc. 28
To be reported to.

Further, the disaster victim determination unit 26 determines from the travel distance information of each disaster victim 5 output by the travel distance measuring unit 25 that the disaster victim has not moved, for example, a victim who has been directly affected by a debris flow, or moves with injury. Extract 5 information of disaster victims who cannot move easily, such as disaster victims, elderly people, physically handicapped persons, and infants, and conclude that they are in need of relief. The victim determination unit 26 automatically provides information to the government office 28 such as a fire station or a police station, and requests a rescue operation.

In this way, all the victims 5 evacuate efficiently and quickly (S-14), and the evacuation guidance is completed (S-15).

In the above-mentioned embodiment, an example was explained in which two places were evacuated by dispersing from the disaster occurrence place, but in order to make it possible to evacuate more safely and swiftly, as shown in FIG. You may do it. The same parts as those in FIG. 1 are described by giving the same reference numerals, and detailed description thereof will be omitted. The choice of evacuation route is aimed at all victims to leave the disaster site as many steps as possible in an instant.

In order to leave the disaster site as much as possible in one step, that is, in order to leave the disaster site as much as one step in an instant, it is necessary to evacuate without issuing evacuation information to concentrate on one evacuation route. Depending on the number of people and the situation of the evacuees, it is necessary to timely determine the number of people who can pass through the evacuation route based on the width of some evacuation routes and the presence or absence of stairs so that the number of evacuation routes will not be exceeded.

For example, the evacuation guidance for the shortest distance roads 36B and 34B to the evacuation site 30 is for persons with physical disabilities, young children,
This is a guide for injured victims and their caregivers.
Next, the relatively close roads 36C and 34A are evacuation guidance-guided for the elderly and those involved. The longest distance roads 36A and 34C are guided by evacuation guidance to healthy persons with high exercise ability. For example, the evacuation guidance for the shortest distance roads 36B and 34B to the evacuation site 30 is for the physically handicapped, the child, and the injured victim. Next, the relatively close roads 36C and 34A are guided by evacuation guidance for elderly people. The longest distance roads 36A and 34C are evacuation guidance for young people.

In the above embodiment, an example of evacuation to a predetermined evacuation site 30 as an evacuation destination has been described, but the evacuation site 30 may be any safe place selected in advance, and a safe evacuation site is a disaster. It is a place where more people can leave the scene of the disaster as many times as possible, depending on the content of the.

In the above embodiment, an example in which the evacuation state of the victim to the evacuation site 30 by the distributed evacuation guidance is detected by the radio waves transmitted from the evacuee's mobile phone has been described.
To count the number of evacuees, the number of evacuees may be counted based on the images captured by the monitoring cameras of the various sensors 2.
According to this embodiment, even an evacuee who does not have a mobile terminal can count out and the true number of evacuees can be counted.

In the above embodiment, an example in which the location of the victim is detected by radio waves transmitted from the mobile terminal has been described, but the location may be detected from the images taken by the monitoring cameras of the various sensors 2. According to this embodiment, the surrounding devices, trees, rivers, mountains, houses, intersections, etc. can be known, and the location can be found more specifically.

Further, in the above embodiment, an example in which the location of the disaster victim is detected by the radio wave transmitted from the mobile terminal has been described. However, since the telephone number is known, the telephone number is known and the location information is confirmed from the parties. You may. According to this embodiment, not only the location information but also the surrounding disaster situation and the situation of the victim who does not have a mobile terminal can be confirmed.

According to this embodiment, a landslide, a crack, a debris flow, a fire, a tsunami caused by a natural factor such as an earthquake, volcanic eruption, bad weather, etc. in a specific area under the jurisdiction of a wide area municipality such as a municipality or a prefecture. Presence or absence of disaster of human beings in the disaster occurrence area at the time of regional disaster such as flood, flood damage, large-scale accident of factories, buildings, etc. and terrorist activity such as fire, collapse of facilities, air pollution, radioactivity leakage, disaster It becomes possible to accurately grasp the location of the occurrence, and to provide evacuation guidance routes that are appropriate for the location of the disaster by promptly providing each victim 5 with various media, making it necessary to evacuate. Accurate information can be transmitted to humans, and it can greatly contribute to life-saving activities.

Further, it is possible to automatically judge a person who has become difficult to move due to a disaster, and also to automatically detect the position of the person, and to automatically provide information to the government offices 28 such as the fire station and the police station. It enables quick contact, and can greatly contribute to lifesaving activities in the event of a disaster.

Furthermore, the current evacuation situation is constantly changing with respect to the evacuation destinations associated with the evacuation of a large number of people and the information terminals 29 of facility personnel and managers in transit and government offices 28 such as fire stations and police stations. By providing the evacuation situation forecast in the future and promptly, we will support the establishment of the management system and the appropriate staffing, etc. to prevent the secondary disaster caused by the evacuation of a large number of people. Evacuation guidance is possible.

Further, at the time of disaster occurrence, the victims 5 at the dangerous place where the disaster occurred are identified by receiving from the data table of the communication company by the mobile phone number list, and the optimum evacuation guidance route is automatically provided to each victim 5. Is notified by a mobile phone number, it is possible to select and guide a course suitable for each disaster victim 5. Further, since the above-mentioned optimum evacuation guidance is distributed and guided to the evacuation site, it is possible to guide evacuation separately for persons of all ages, men and women with physical disabilities, injured persons, and each person can evacuate quickly.
