Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an evacuation guidance system for a water disaster that gives an advance notice of the occurrence of water damage due to an increase in rainfall, etc.

[0002]

2. Description of the Related Art Reservoirs of power plants flood when typhoons and long rains continue for a long period during the summer season. In order to protect the dam at the power plant, when the water level in the reservoir exceeds a specified value, water is discharged to the river from the viewpoint of dam strength. This water discharge is an indispensable means to protect the dam. It is impossible for the general public to predict under what conditions water will be released,
Neither the TV, the radio, nor news media such as newspapers have predicted the dam's water discharge. Persons concerned with the dam only issued warnings of water discharge suddenly with sirens and speakers to people in the river that was the water discharge channel several hours before the water was discharged, and measures such as evacuation guidance and display and broadcasting of evacuation guidance routes were carried out. I haven't been.

[0003] Therefore, since the alarms of people involved in dams are unilateral, they are not understood by the general public, and the family gap that they enjoyed camping in Nakashu in the river last year suffered water shortages, and many lives were lost. It was an accident. Furthermore, flash floods and mudslides occur when there is heavy rain in the mountains, and they often cause accidents that lead to the loss of lives by burying houses and burying residents living inside the houses. Furthermore, the heavy rainfall in the upstream of the river increases to an unpredictable water level in the downstream near the sea, and when the high tide overlaps in the downstream with little rainfall, the river overflows, causing an accident.

[0004]

In many cases, the above-mentioned water damage has not been predicted, and the above-mentioned accident is repeated. A means for displaying a map of evacuation sites to residents when a natural disaster such as a flood occurs is disclosed in JP-A-11-2999.

It consists of 11.

There are cases where water and debris flow overflowed from rivers, mountains, the sea, etc. historically and geographically in the flood forecast area.
Such areas are designated as dangerous areas in predetermined areas, such as underground areas or low areas where such water flows in. Examples of the flooding forecast area are a dam reservoir 25, a river (river) 26 that serves as a dam discharge channel, a dangerous area A area 27 and a dangerous area B area 28 located on the shore of the discharge channel. In the dangerous area A area 27 and the dangerous area B area 28, there are houses 29 and roads 31 through which cars and people (evacuees) 30 pass.

The water level measuring unit 2 is composed of a water level meter 32, such as an optical fiber sensor, provided at one or a plurality of locations in the above-mentioned flood forecast area. This optical fiber sensor measures the water level, converts it into an electric signal, and outputs it as water level data. The water level data is converted into a digital signal and stored in the water level database 34 of the water level increase information storage unit 5 together with the date of measurement and the place name via the dam management device 33.
The embodiment of the water level measuring unit 2 is, as shown in FIG.
5, near the bank with a high possibility of overflow of the river 26 passing through the dangerous area A district 27 and the dangerous area B district 28.

The rain amount measuring unit 3 stores rain water in a water storage container having an opening of a predetermined area by a rain gauge 36 provided at one or a plurality of locations in the above-mentioned flood forecast area, and measures this water amount by an optical fiber sensor. The generated electric signal is output as rainfall data. The rainfall data is converted into a digital signal and stored in the water level database 34 of the water level increase information storage unit 5 as the rainfall data together with the measurement date and time and the place name via the dam management device 33. It is desirable that the embodiment of the rainfall measuring unit 3 is installed near the water level gauge 32.

The water level data and the rainfall data measured by the water level gauge 32 and the rain gauge 36 in the dangerous area A district 27 and the dangerous area B district 28 (expected flood area) are described above through the respective district data collecting devices 37 and 38. As described above, it is stored in the water quantity database 34 for each place together with the measurement date and time and the place name. Further, the local water amount database 34 is further input with the weather map announced by the Japan Meteorological Agency and the rainfall prediction data estimated from the rainfall amount in each region by the rainfall prediction data output unit 39, and stored together with the input date information.

Dam water discharge amount determination unit 40 of the dam management device 33
Indicates the time of arrival at the dam's predetermined water discharge level from the output of the water level gauge 32 and the rain gauge 36 provided in the dam's reservoir 25 from the meteorological map announced by the Japan Meteorological Agency or the rainfall prediction data output unit 39. The water discharge time and water discharge of the dam are determined by forecasting from rainfall prediction data. After that, the information providing unit 41 informs the people who are swimming in the river 26 from the existing speakers provided along the bank of the river 26.

Next, the water level increase rate calculation unit 4 reads out the water level data measured by the water level measurement unit 2 and increases every predetermined unit time from the water level increase information storage unit 5, and increases with time from this water level data. The rate of water level rise is calculated and the water level rise rate data is automatically output.

Further, the increasing speed information calculating unit 4 reads out the rainfall amount data which increases with time in a predetermined unit time in the rainfall measuring unit 3 from the water level increase information storing unit 5, and calculates the increasing rate of this rainfall data. Calculate and automatically output rainfall rate data. In this way, the increasing speed information calculation unit 4 automatically obtains the increasing speed information of the water level and the rainfall amount per unit time. The water level and rainfall increase rate information are input to the dangerous water level arrival time calculation unit 6.

Next, the dangerous water level arrival time calculation unit 6 will be described. The dangerous water level arrival time calculation unit 6 estimates the possibility of reaching a preset dangerous water level (flood occurrence water level) from historical data, that is, data on the amount of rainfall increase up to now, relational data on the occurrence of floods, and rainfall prediction data. To do. For reachability, for example, the arrival time is inferred (AI) determined and automatically output. When the arrival time to the dangerous water level (flood water level) is calculated in the dangerous area A area, for example, the dangerous water level arrival time calculation unit 6 outputs the flood damage warning information to the dangerous area A area to the flood damage warning announcement area determination unit 7. .

The flood damage announcement area determination unit 7 confirms the time of flood occurrence, the place, the necessity of evacuation, etc., and outputs "issue of flood damage announcement information in the dangerous area A area". The flood disaster warning announcement area determination unit 7 notifies the fire department / police station rescue request unit 8 of the flood damage warning information announcement in the dangerous area A through the information collecting unit 43.
Is output. Further, the flood damage warning announcement area determination unit 7 outputs the flood damage warning information “issue of flood damage warning information to the dangerous area A area” to the evacuation route data selection unit 9. Further, the flood damage warning announcement area determination unit 7 outputs the "Disaster warning warning information announcement in the dangerous area A area" on the screen of the personal computer 63.

Since the evacuation route data selection unit 9 is dangerous because water damage may occur in the dangerous area A area 27, it is an optimum evacuation path for residents in the dangerous area A area 27 and vehicles traveling in these areas. Is output. The optimum evacuation route is a road that can be safely driven even in the rain, which does not pass through the road in the dangerous area A area 27 for which flood damage notice information has been issued. Therefore, the evacuation route data selection unit 9 stores the evacuation guidance route database 12 in which a large number of evacuation guidance route maps are stored.
The evacuation guidance route pattern is sequentially read from and the optimum evacuation route map that allows the user to go to a predetermined evacuation site 44, for example, a gymnasium without passing through the danger zone A area 27 for which flood damage has been announced is selected. The optimal evacuation route map is, for example, a diagram in which the direction of evacuation is described on the map.

The evacuation route data selection unit 9 is provided with an optimum evacuation guidance route selection unit 45, and the optimum evacuation guidance route selection unit 4 is provided.
Reference numeral 5 confirms and selects (searches) the safety information from the safety information section 46 as a selection route for guiding to the evacuation site 44. If it is found that at least one of the evacuation sites and routes selected for the optimal evacuation guidance route map cannot be used, the optimal evacuation guidance route map corrected from the keyboard of the PC 63 to another usable evacuation site or route map is displayed. Notify me. In other words, if it is determined that multiple evacuation sites and evacuation routes whose safety has been confirmed in advance are dangerous areas that cannot be used or passed due to some factors, they cannot be used by disaster guides and dam personnel. Provide information. The person in charge of disaster guidance searches the evacuation guidance database 12 for the most appropriate evacuation guidance method by human work, and places the retrieved information on the evacuation site and the evacuation passage of the most suitable evacuation guidance method in the vicinity of the dangerous area. Provision to humans, humans in buildings such as houses in the dangerous area, and automobiles running or stopped in the dangerous area.

Confirmation of safety information collects non-safety information that has suddenly occurred, such as roads and construction in areas where flood damage has been announced, steep slopes, tunnels that may be flooded, narrow roads, and traffic accidents. A safe road modified on the condition of is selected as the optimum evacuation route. In this way, the place designated as an evacuation site or evacuation route suddenly becomes inoperable due to flooding, construction, or traffic accidents.In such cases, the non-safe zone is modified. By informing the evacuees, safe and reliable evacuation guidance is possible.

The evacuation route data annunciation unit 10 has issued the flood damage warning information to the residents and the eyes and ears of the driver of a passing vehicle in the dangerous area A area 27, which is the area where the flood damage warning information has been announced. The optimum evacuation route map is automatically displayed 47. For cars passing through the dangerous area A area 27,
Guide display of safe detour roads. If necessary, the evacuation route data notification unit 10 also notifies people who are swimming in the river 26.

The evacuation route data notifying section 10 displays an optimum evacuation route map on an electronic display board as an optical display means and guides it, and also broadcasts it from a speaker as an auditory display means to guide it. It is desirable to install the electronic display board and the speaker at each intersection on the road, and it is desirable to also use the intersection with a sign. In addition, the driver in the vehicle can be automatically guided to the car navigation.
This guide is the dangerous area A area 2 where the flood damage notice information was issued.
Not only 7 but also notification section 4 for people outside the hazardous area and managers
It is desirable to notify people in the surrounding area and automobiles from 9 onwards.

The evacuation route data notifying unit 10 is provided with an evacuation guidance notifying device 48 which is a drive circuit for guiding the selected optimum evacuation route map by means of an electronic display board, an LED display, a traffic sign, a car navigation and a speaker. Many are provided.

The evacuation person monitoring section 11 monitors whether or not the evacuation person has evacuated during the period from the issuance of the flood damage notice information until the occurrence of a disaster. The purpose of monitoring evacuees is to find out if there are any people who are lost on the way, who are injured and unable to act, and who are physically handicapped people who have difficulty evacuating. Is. TV cameras are installed in the areas 27 and 28 of the predetermined dangerous areas A and B as monitoring means so that the evacuation situation can be monitored. The people with disabilities and sick people who have been delivered in advance are
Rescue from the fire department and police station.

The evacuee monitoring unit 11 monitors the evacuation status of residents in the dangerous area A area 27 and the dangerous area B area 28 and the entrance / exit status such as the traffic status of automobiles by installing a monitoring device 51 such as a TV camera. It is confirmed by the judgment units 55 and 56 that there are no evacuees or automobiles in each district, and the result is stored in the person / vehicle database 52 together with the date information. The evacuation status stored in the person / vehicle database 52 is confirmed by the evacuation status confirmation unit 53.

On the other hand, the monitoring device 57 provided in the evacuation site 44, for example, a TV camera, monitors the evacuation situation by imaging the people who have evacuated, and the evacuation completion determination unit 58 confirms that all the people have evacuated. Is stored in the person / vehicle database 52.

Since it is expected that the monitoring means by the TV camera will not operate in the event of a sudden disaster, the residents in the dangerous area A area 27 and the dangerous area B area 28 are registered in advance as an evacuation countermeasure in case of a disaster. When a contactless data carrier (IC card) is provided by the data carrier system as a proof of being a resident and the person evacuates to the evacuation site 44, the contactless data carrier is previously stored in the evacuation site 44.
Evacuation can be automatically confirmed by communicating with the responder installed in. By inputting information such as name, address, and blood type into the non-contact data carrier, it is effective in medical treatment such as accident or injury.

The evacuation status confirmation unit 53 reads from the person / vehicle database 52, and reads the dangerous area A district 27 and the dangerous area B.
After confirming that there are no people or cars in the district 28 and confirming that all the evacuees have evacuated to the evacuation site 44,
Flood information / evacuation victim evacuation information receiver 54 of the information collector 43
It is automatically output to the fire department / police station 8 via.

In the person / vehicle database 52, a list of residents in the dangerous area A area 27 and the dangerous area B area 28 designated as dangerous areas can be stored. In this case, if the names of the evacuees evacuated to the evacuation site 44 are known, it is possible to quickly determine whether or not all the residents can evacuate. In particular, if Silva, such as a physically handicapped person, an elderly person, and a child, is registered in the resident list separately, Silva can preferentially provide rescue assistance and quickly evacuate. Further, when there is a person who has not been evacuated, the unevacuated person can confirm the current location and current state by address, mobile phone, telephone, etc., and can carry out rescue activities smoothly. If necessary, the missing person requests the fire station / police station 8 for rescue.

That is, the respective monitoring devices 51 provided in the dangerous area A district 27 and the dangerous area B district 28 output to the presence / absence determination units 55 and 56 of the evacuees and the automobiles and the A and B districts 2 respectively.
The presence / absence of vehicles and evacuees in 7 and 28 are determined, and the evacuation / vehicle presence / absence determination units 55 and 56 output these evacuation situations, and the evacuation situations are stored in the person / vehicle database 52.

Further, the monitoring device 57 provided in the evacuation site 44 monitors the evacuation situation to the evacuation site 44 and outputs it to the evacuation completion determination section 58. When the evacuation completion determination unit 58 confirms the evacuation completion, the evacuation completion information is stored in the person / vehicle database 52. The evacuation completion information stored in the person / vehicle database 52 is read by the evacuation status confirmation unit 53 and automatically reported to the fire station / police station 8. In this way, the evacuation guidance system 1 for water disaster is constructed.

Next, an evacuation guidance method when an evacuation notice is issued by the evacuation guidance system for a water disaster will be described with reference to the flowchart of FIG. The same parts as those in FIGS. 1 and 2 are described by giving the same reference numerals, and detailed description thereof will be omitted.

Each of the water level gauges 32 provided in a predetermined flood forecast area measures the water level data (S-
1) is the water level database 3 in the water level increase information storage unit 5
It is stored in 4 together with the measurement date and time (S-2). At the same time, the rain gauges 36 are the water level gauges 3 of the dam 25 and the river 26, respectively.
The rainfall data (S-1) provided by the rain gauge 31 provided in the vicinity of 2 is stored in the water amount database 34 of each water level increase information storage unit 5 together with the measurement date and time (S-2).

The increasing speed information calculating unit 4 reads the water level data and the rainfall amount data stored in the water amount database 34 for each area, and calculates the water level increasing velocity and the rainfall increasing rate per unit time (S-3). It is desirable to display these changes in a graph on the display device 63. This water level increase rate and rainfall increase rate are calculated based on the water amount database 34
The measurement date and time are stored in. The dangerous water level arrival time calculating unit 6 reads out the water level rising speed and the rainfall increasing speed stored in the respective water quantity database 34, and calculates the possibility of reaching a predetermined dangerous water level, for example, the arrival time. When such a step is repeated and, for example, a heavy rainfall occurs in a mountain, the water level in the dam reservoir 25 rises rapidly, and the water level rising speed and the rainfall increase speed also suddenly increase. As a result, the dam reservoir 25 becomes full and the dam discharge is started.
The discharge of this dam flows through the river 26, and at the same time, the river 26
It may overlap with the high tide of the sea on the downstream side of. As a result, the area of the river 26, which is said to be relatively low, is flooded.

It is desirable that the evacuation be completed before the occurrence of this flood by predicting the occurrence of this flood as follows. In the area of the river 26 which is said to be relatively low, the local government has previously designated a dangerous area as a special monitoring area based on past cases, and water damage protection measures have been taken. Therefore, river 2
In the comparatively low area of 6, the water level that causes flooding is set and registered as the dangerous water level in advance. The dangerous water level arrival time calculation unit 6 performs data calculation (inference) on the expected water level rise rate based on the above-mentioned water level rise rate, rainfall increase rate, weather forecast map announced by the Japan Meteorological Agency, future expected rainfall amount announced by the Meteorological Agency, and information such as when the tide is full. ) Then, the possibility of reaching the dangerous water level set in advance for each dangerous area from past cases etc. is calculated, for example, by simulating the time (S-4).

As a result of this calculation process, when the dangerous water level arrival time calculation unit 6 calculates the area where the dangerous water level is reached (S
-5), The flood damage announcement area determination unit 7 automatically outputs (issues) flood damage announcement information to the area (S-6). The flood damage announcement information is automatically input to the fire station / police station 8 for a rescue request (S-7), and at the same time is automatically input to the evacuation route data selection unit 9. The optimum evacuation guidance route selection unit 45 of the evacuation route data selection unit 9 sequentially reads the pre-stored evacuation guidance route map from the evacuation guidance route database 12, and the area informed of the flood damage from the safety information unit 46, the road under construction, etc. The evacuation guide route map, which is confirmed to be safe without passing through roads that hinder traffic, is simulated (selected) 9 as the optimum evacuation guide route map and automatically output (S-8).

The selected optimum evacuation guidance route map as shown in FIG. 4, for example, is automatically displayed optically and acoustically on the road in the area where the notice of flood damage is issued, for example, the dangerous area A area 27. As an optical display, an optimal evacuation guidance route map as shown in FIG. 4 is electronically displayed on an electronic display board. The audio display indicates the optimal evacuation guidance route to the evacuation site 44 by voice from a speaker. Furthermore, for persons who are difficult to evacuate by themselves, such as physically handicapped persons and sick people, fire department personnel and police officers rescue and evacuate (S-9). The evacuation situation is shown in FIG. 4 and 5, the same parts as those in FIGS. 1 to 3 are designated by the same reference numerals, and detailed description thereof will be omitted. In FIGS. 4 and 5, the arrow 60 indicates the optimum evacuation guidance direction.

The evacuation situation of the person 30 is the dangerous area A area 2
It is monitored by a plurality of TV cameras installed in 7. When there is an evacuee 30 who is lost, the speaker guides the evacuee 30 to the evacuation road by voice. In particular, the river 26 flows through the central part of the dangerous area A district 27, and the evacuees 30 who are in the bend of the river 26 cannot go to the evacuation site 44 unless they cross the bridge 61. The amount of water in the river 26 has increased to the extent that it is evacuated, and it has become a torrent. For evacuees this river 26
You will be guided to cross the bridge 61 hung over.

Further, for a vehicle passing through the dangerous area A area 27, an optimum road 31 bypassing the dangerous area A area 27 is introduced by car navigation, electronic display, voice or the like via a VICB beacon. A TV camera is installed in the evacuation site 44 as a monitoring device for confirming the evacuees, and the TV camera confirms the presence or absence of unevacuated persons (S-10). If there are no unevacuated persons, it is assumed that all have been evacuated, and the rescue operation ends (S-11). If there are unevacuated persons, that is, if there are evacuees remaining, the rescue operation is performed again.

If the owner of a mobile phone or information terminal, the rescue operation is an activity of calling by using a mobile phone registered in advance to check the current position and provide guidance. If you are injured while you are evacuating, the fire department officers and police officers will help the evacuees 30. In this way, all the target persons complete the evacuation to the evacuation site 44.

As described above, the evacuation guidance system and method for a water disaster of this embodiment issues the water disaster notice information before the water disaster occurs, so that a fatal person due to the water disaster can be eliminated. it can. When evacuation guidance is performed when a water disaster occurs, the rescuer may also become a victim, but by evacuating in advance, it is possible to evacuate relatively without panic and to evacuate without a victim. Since the water disaster notice information is automatically issued, it is possible to notify evacuees early.

Further, this embodiment is applied to a person in and around a dangerous area where water damage or the like occurs, a person in a building such as a house in the dangerous area and an automobile running or stopped in the dangerous area. On the other hand, it is possible to provide dangerous information such as the water level of the dangerous area and to select an optimal evacuation guide route map from the preset evacuation guide route map to the evacuation site to perform appropriate evacuation guidance. By automatically providing this information provision / evacuation guidance using various media, it can be surely transmitted to all people. Furthermore, it is possible to promptly provide disaster information to relevant persons, managers, and fire departments, police stations, etc. outside the danger area.

Furthermore, if a safe evacuation site or evacuation guide diameter cannot be selected, a rescue request can be promptly made and the life saving activity can be greatly contributed.

In the above embodiment, the occurrence of flood caused by water discharge of the dam was explained as a water disaster. However, in the case of a natural disaster caused by water, in any case such as a landslide in a mountain or a disaster caused by flash flood, by issuing water disaster notice information. You can safely evacuate.

[0065]

According to the present invention, a region where a water disaster is likely to occur is estimated and automatically notified in advance, and the relevant evacuation route information is automatically notified to relevant persons, so that rescue activities can be promptly performed. Can be converted.
