BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, an embodiment of a disaster prevention and rescue system according to the present invention will be described in detail with reference to the drawings.

FIG. 1 is a system configuration diagram showing an embodiment of a disaster prevention and rescue system according to the present invention. Broadly speaking, a disaster is generated based on detection output signals from various types of disaster prevention detection equipment installed in a building. Disaster prevention and rescue computer 1 for predicting presence / absence, expansion or reduction status, searching for evacuation routes, etc.
0, a route alarm group 20 for notifying a person present in the building of the searched evacuation route, a transmission / reception for transmitting / receiving information on an intrusion route, an evacuation route, etc. with a disaster prevention countermeasure staff such as a fire engine or a person present in the building. It comprises a machine group 30 and a backup system 40 having the same function as the disaster prevention and rescue computer 10.

In this embodiment, a relatively large-scale building, such as a building, is assumed, and in cooperation with an in-building central control computer 50 for centrally managing various facilities in the building, support for disaster prevention and rescue in the event of a disaster is provided. An example is shown.

Normally, the centralized control computer 50 in a large-scale building constantly monitors the output signals of a group of sensors 60 such as fire detectors installed at predetermined intervals to detect the presence or absence of a fire or the like. And a group of sprinklers 701 and a group of fireproof shutters
2, elevator / escalator group 703, air conditioner group 7
04 is controlled via drive control units 705-708.

The operation state or control state of these various disaster prevention facilities and incidental facilities is sequentially updated and stored in the external storage device 709. Furthermore, at the time of a power failure, power is supplied from the uninterruptible power supply 710. Then, a control instruction is issued by the administrator from the operation panel 711, and the current control state and the like are displayed.

In this embodiment, the output signal of the sensor group 60 used by the in-building central control computer 50 is taken into the disaster prevention and rescue computer 10 via the data input / output unit 80, and the occurrence of a disaster such as a fire is detected. When a disaster occurs, a group of sprinklers 701 and a group of fire shutters 702
Disaster prevention equipment or elevator / escalator group 70
Ancillary equipment such as the air conditioner 3 and the air conditioner group 704 are controlled on the safe side via the centralized control computer 50 in the building.

In this case, the centralized control computer 5 in the building
In a building that is not equipped with a computer 0,
Directly from the sprinkler group 701 and the fire shutter group 702
Disaster prevention equipment or elevator / escalator group 70
It goes without saying that incidental facilities such as the air conditioner 3 and the air conditioner group 704 are controlled on the safe side.

The disaster prevention and rescue computer 10 and the backup system 40 of the present embodiment include an uninterruptible power supply 71
The power supply for operation is also supplied by 0 when a power failure occurs.

The disaster prevention and rescue computer 10 shown in FIG.
Disaster, weather, personnel, etc. data management unit 101, disaster expansion /
Reduction prediction unit 102, evacuation / intrusion / rescue route search unit 10
3. Firefighting / rescue team equipment installation control unit 104, traffic regulation /
Emergency vehicle route instruction unit 105, inter-system link control unit 10
6 is provided. These are configured by computer programs that can be executed by the arithmetic unit 112.

An operation panel 107 for displaying various instruction operations and the current status, a route display control unit 108, a transmission / reception control unit 109, an inter-system transmission / reception unit 110, reception from other systems and portable information terminals in a building. An external storage device 111 for storing data, structural data of the building, and the like, and a calculation unit 112 for controlling the whole are provided.

As shown in FIG. 2, the sensor group 60 includes a smoke detector 601, a fire detector 602, a gas detector 603, an infrared detector 604, a meteorological meter 605, an entrance / exit sensor 606, a flood detector 607, Strain (collapse) detector 60
8 and the like. The gas detector 603 detects gas harmful to humans, the infrared detector 604 detects the presence of humans, and the distortion (falling) detector 608 detects abnormalities in mechanical distortion such as pillars. To predict the danger of collapse.

The route alarm device group 20 is composed of a conventionally used evacuation guide plate 201 with an arrow and a device for displaying an evacuation direction such as an arrow on a floor 203 from a floodlight 202 mounted on a ceiling. , Used with existing broadcasting equipment.

The transmitter / receiver group 30 includes a portable information device transmitting / receiving section 301 for transmitting / receiving signals to / from a portable communication terminal 302 such as a portable telephone or a PHS telephone carried by a person in the building, a firefighter, etc. A portable communication device for firefighting, which transmits and receives signals to and from a portable communication terminal carried by the user or a wireless terminal installed in a fire truck 305; an IC card 307 (or equivalent) carried by a person in the building. It comprises an inter-IC card receiving unit 306 for receiving personal information transmitted from a function device).

In this case, the IC card 307 (or a device having the same function) is provided with the unique information of the person carrying it,
That is, in addition to information on name, age, and contact information, information such as whether evacuation is possible in case of a disaster and the ability to step on obstacles such as stairs are registered in advance, and the information is constantly transmitted by radio signals. ing.

When each person has a portable communication terminal 302 such as an IC card 307 (or a device having an equivalent function) or a portable telephone, it is possible to obtain personnel distribution information by capturing radio waves emitted from the terminal. And, since codes can be assigned and managed for each individual, it is possible to identify who is where and where evacuation is performed in detail, taking into account the characteristics that affect the determination of evacuation routes, such as using a wheelchair, for each individual. The route can be set.

It is relatively easy for everyone to have a portable communication device in a hotel or a building of each company. However, in a department store or a station where an unspecified number of people enter or leave, not everyone has a portable communication device. It is not always possible.
In that case, a gate is provided at each entrance and exit of each floor of the building and at the boundary of the three-dimensional block or three-dimensional group, and personnel distribution information is obtained by an entrance / exit passage sensor 606 that counts the number of persons passing through the gate based on the number of light beams blocked. In this case, it goes without saying that evacuation routes cannot be finely set for each person, but there is a problem that an error may occur in the number of people counted. At this time, only the staff distribution information is used for the evaluation of the degree of congestion when evacuation routes are determined.

The information on fire and the like and the personnel information thus obtained are transmitted to the transmission / reception control unit 109 by radio signals together with the identification numbers unique to the detectors used for determining the installation locations of various detectors. The received information is sent from moment to moment to the calculation unit 112 of the disaster prevention and rescue computer 10, where it is used to calculate the evacuation route and the intrusion route of rescue personnel. In places where radio waves are difficult to transmit, a repeater that receives and relays radio waves from a detector or a mobile communication terminal is required. If information from the installed detector cannot be received,
Whether the failure is due to a mere failure or the influence of a fire or the like is determined based on information from a peripheral detector.

FIG. 3 is an explanatory diagram showing processing units in the case where a disaster has occurred, prediction of an enlargement / reduction state, and search for an evacuation route according to the present invention.
As shown in FIG. 3A, one floor of
Each of the three-dimensional blocks 12 is divided into three-dimensional blocks 12 as shown in FIG. 3 (b) or a plurality of three-dimensional block groups 13 and 14 as shown in FIGS. 3 (c) and 3 (d). The three-dimensional block 12 or 3
The presence or absence of a disaster is monitored by disaster prevention detection equipment installed for each of the dimension block groups 13 and 14. Then, when a disaster occurs in one of the three-dimensional blocks 12 or the three-dimensional block groups 13 and 14, all the three-dimensional blocks 12 or the three-dimensional block groups 13, 1
4, the current state of the disaster is determined based on the output of the disaster prevention detection equipment, and the situation of the expansion or contraction of the disaster is predicted. Based on the prediction result, the entrance / exit 15 leading to the safety area or the outside of the building by avoiding the danger area. , 16 and 17 is searched for an evacuation route according to a predetermined route search algorithm, and a route instruction leading to the searched route is performed.

The entrances 15, 16 in FIG.
The three-dimensional block of the shaded display portion up to 17 indicates a normal passage. One three-dimensional block 12 is
The width is set to be approximately the same as the normal passage width. In addition, 1
Each of the three-dimensional blocks 12 has a minimum size that allows one person to pass through. For example, if one three-dimensional block 12 is set to the size of “1 m × 1 m × 1 m”, 10,000 3
Divided into dimensional blocks. Even if the processing time per block is 100 μS, the processing time for one floor is 1 second, which can be sufficiently handled by the capabilities of recent personal computers.

In one three-dimensional block 12 or three-dimensional block groups 13 and 14, as shown in FIG. 3B, fire detection information 121, toxic gas detection information 122, flood detection information 123, distortion (falling) detection The information 124, the number of people passing 125, the disaster prevention equipment operation status information 126, the building structure information 127, the weather information 128, and the like indicate whether or not a disaster has occurred, and whether or not the disaster has spread or reduced, in one three-dimensional block 12 units or 3 units. Dimension block group 13,
Monitored by 14 units. Also, the number of persons existing there is managed.

FIG. 4 shows an overall processing flow of the present system.

Even during normal times, the disaster prevention and rescue computer 10 of FIG. 1 receives information from the detector / portable communication device / control terminal or the like through the transmission / reception unit control unit 109 (step 401). In addition to the fire information, personnel distribution information, weather information, temperature and oxygen / various gas concentration information, operation status information of various facilities in the building, fire brigade personnel /
Equipment information, instructions to manually add individual information to own system, operation control instructions to own system when linked to other systems,
When various information such as interlocking information received from the same type of system is received, the data management unit 101 such as disaster, weather, personnel, etc.
, The relevant information is stored in the external storage device 111 as received data.

When a fire is detected in any of the three-dimensional blocks or three-dimensional groups (step 402), the disaster prevention and rescue computer 10 analyzes the received data and specifies the source of the fire. In addition, information on disaster and personnel distribution is also obtained (step 403). Further, the disaster prevention and rescue computer 10 grasps the operation status of various facilities in the building (step 405), and the centralized control computer 50 in the building.
, The sprinkler group 701 at the fire detection point is operated to start fire extinguishing activity control. At the same time, communication of a fire occurrence and provision of necessary data are made to a fire department or police department in charge by a radio signal or a wire-only line signal using a communication line or the transmission / reception control unit 109.

Next, the spread of a fire is predicted (step 406). FIG. 5 shows the detailed flow.

At steps 501 and 502, the presence or absence of the previous measurement information is determined for each of the fire adjacent locations. At first, the measurement information is not yet available,
At this stage, the first forecast of the spread of fire
As shown at 04, the spread is calculated using a value predicted from the structure of the building in advance. Floor / wall /
In consideration of the material of the ceiling, the material of the object being placed, the existence of windows / doors, the size of the opening, the piping, etc., a value that can be used as a clue for the speed of the spread of fire in a windless state is set. This value is recorded for each location of the building (for each 3D block or 3D block group) as the rate of increase in temperature, the rate of decrease in oxygen concentration, and the rate of increase in carbon monoxide / carbon dioxide concentration. deep. In addition, the increase rate of the concentration of other various harmful gases can be added depending on the situation specific to the building. Considering the operating state and wind direction of the sprinkler group 701 and the operating state of the fireproof shutter group 702 to these values,
Correction is made (steps 508 and 509). For example, if the fire prevention shutter is operating, various increase rates are corrected to “0”. Also, if the air conditioner is working,
If the window is open and the wind speed is high, correct the value so that the fire spreads downwind.

After the elapse of a certain time, the latest fire situation is obtained again, and the difference from the previous time is calculated (step 50).
3) Obtain the rate of increase of the various values, which is a clue for estimating the speed at which the fire spreads (or shrinks) (5)
05, 506, 507). At this time, weather conditions such as wind direction and wind strength are recorded, and if this changes, the estimated value is reflected in the estimated value. In addition, the rapid spread of fire, often called flashover, which occurs during a fire, can be predicted to some extent by comparing the material of the walls and ceiling and the pattern of the time lapse of temperature with past examples. The data is reflected and stored in the route search mesh table (step 510). Attribute data unique to the building such as materials of walls and ceilings is registered in advance by being included in the building structure data.

The above procedure is repeated in all the places adjacent to the fire (step 511). The route search mesh table is a table that stores various information for each three-dimensional block or three-dimensional block group, and will be described later with reference to FIG.

Considering such a fire spread prediction, the arrangement or distribution of personnel, and the presence or absence of an evacuation route obtained by a calculation method described later, which of the fireproof shutter groups 702 in FIG. It is determined whether or not to operate, and the determined fireproof shutter is operated through the in-building central control computer 50. The escalator will be shut down altogether to avoid the danger of concentration of personnel during evacuation. In addition, the elevator stops everything on the middle floor that goes into the fire spread area at the nearest floor, closes the doors after passengers descend, and stops. Air conditioning equipment group 704
However, since there is a risk that the pipes may spread the fire, the operation is stopped except for the smoke exhaust system in the event of a fire, and if possible, the intake and exhaust ports are controlled to be closed.

In step 407 of FIG. 4, the persons stored in the personal information storage master table 610 of FIG. 6 are grouped into one group of persons having the same location and the same class of route traversing ability coefficient, and the evacuation shown in FIG. User group table 1000 is created. Then, an evacuation route is obtained for each group. Further, the guidance order among these evacuee groups is determined using the location table 800 shown in FIG. 8 in the order of earliest expected fire arrival time at the location, and stored in the guidance order management table 1500 shown in FIG. . The estimated fire arrival time in this case is estimated from the result of the fire spread prediction in step 406 in FIG.

The guidance order management table 1500 shown in FIG.
Stores the leading address 1501 of the guidance target location table and the final address 1502 of the guidance target location table.

In step 408 in FIG. 4, evacuation or intrusion routes are calculated for all groups using the above-mentioned table. FIG. 16 shows a detailed processing flow of the evacuation / intrusion route search. In FIG. 16, in steps 1601 and 1602, it is determined whether each evacuee group is an evacuee target or a fire brigade member in the same location unit according to the guidance order.

If the subject is an evacuation target, an evacuation route is searched for between the location and all emergency exits in the same building using a maze algorithm. In the case of a firefighter, a search is made for an intrusion route between the location and all the fire sources using the same maze algorithm.

In steps 1603 and 1604, a search for an evacuation route is started between the evacuee and the location of the rescue squad and all emergency exits in the same building.

How to find the evacuation route of the refugee using the maze algorithm will be described below with reference to FIG.

FIG. 21 is a diagram for explaining a route search on a two-dimensional plane of a certain floor. First, it is assumed that the floor is divided into 6 × 6 meshes 21-1 based on the width of the passage. Each mesh will be referred to as a mesh (X, Y) using the arrangement order from the lower left in the X direction and the Y direction. 21-2 corresponding to the mesh (4, 4) is a fire occurrence location, and a route for guiding the refugees at 21-4 corresponding to the mesh (5, 2) to the emergency exit 21-5 is searched. The predicted location of the spread of the fire is determined by the method described above.
Suppose that it is obtained as shown by 3. In the example of FIG. 21, for simplicity of description, the description is omitted and not particularly specified,
Obstacles such as building walls and closed fire shutters
An impassable flag is set on the corresponding side.

First, from step 1605 in FIG. 16, the mesh (5, 2) at the location 21-4 of the evacuee and the emergency exit 2
From both of the meshes (5, 7) of 1-5, meshes are sequentially searched for each adjacent mesh. If it is not possible to go diagonally, the mesh 21-4 at the location of the refugee is set to "1", and "2" is the left and right and upper and lower 4
It is attached to several places. At this time, the mesh (5, 3) is a predicted location of the spread of the fire,
In step 06, the speed is obtained from the evacuees' ability to walk through the route and the state of the route, the arrival time of the corresponding mesh is obtained from the speed, and the fire temperature and gas concentration at the arrival time are obtained from the increase rate (step 1607). Then, as a result of determining whether or not the evacuee can pass through the route through the route, it is determined that the evacuee can pass, and thus the vehicle is allowed to pass (step 1609). Then, the mesh is registered in the route search mesh table 1200 together with the starting point as a candidate point of the intermediate route. However, at that time, if the mesh is already registered as a route candidate point in the middle of the same start point, the search is terminated.
At this time, the emergency exit / fire source is set as the same starting point to avoid double recording (step 1610). Similarly, from each of the meshes in the search order “2”, the search order “3” is assigned to the meshes that can pass vertically and horizontally. Mesh (4,
For the 3) and the meshes (5, 4), it is determined that it is not possible to pass in the search order “3” using the same determination of the route-traversing ability as described above, and thus it is determined that the number “3” cannot be assigned.
Only the meshes that can pass in this way are assigned numbers “1”, “2”, “3”,. . . Similarly, from the emergency exit 21-5, "(1)", "(2)",
"(3)",. . . And add a mesh (2,
In (5), "7" and "(6)" meet (step 161).
1). From here, returning to the original location one by one, a route is obtained (step 1612). This search algorithm is called the "Lee's maze method" used in the automatic wiring technology, and even a complicated route can be found as long as the route exists, so that a very versatile program is realized. The route search algorithm called “Lee's maze method” is described in the document “CYLee,” An Algorithm for Path Connection and It.
s Application “IRE Trans.on Electronic Computer
s, Vol. EC-10. No. 3 (September, 1961), pp 346-365 ", and a description thereof will be omitted.

In step 1613, the obtained route is stored in the route management table in a process for preventing the evacuees from temporarily concentrating on a certain point on the evacuation route thus obtained and making it impossible to pass. 1300, the number of people passing through each mesh is added to all the meshes on the route, and a process of temporarily prohibiting the passage of meshes exceeding twice the allowable number of people is added. When the routes for all the evacuee groups have been obtained, the processing is terminated (step 1614).

FIG. 22 shows that the evacuees have a high ability to cross the route.
This is an example of a case where the moving speed is doubled as compared with the evacuees in FIG. 21-2 corresponding to the mesh (4, 4) is a fire occurrence location, and a route for guiding the refugees at 214 corresponding to the mesh (5, 2) to the emergency exit 21-5 is searched. Assuming that the spread of the fire is determined as shown in 21-3,
This is exactly the same situation as in FIG. However, since only the moving speed of the evacuees has been doubled, the traffic conditions at the predicted location of the spread of the fire are eased by a factor of two. That is, in FIG. 21, when the traffic condition of the mesh (5, 3) is larger than the third search order, the traffic is not allowed. In FIG. 21, when the traffic condition is larger than the sixth, the traffic is not allowed. . For this reason, in the case of FIG. 21, since the mesh (6, 5) which could not pass can be passed,
The shorter path shown in FIG. 7 is selected.

As described above, since the route is searched under the condition of the individual refugee, a more detailed evacuation route can be presented. Therefore, an evacuation route can be searched for in response to the ever-changing fire situation. Of course, in the actual evacuation route search, a three-dimensional search in consideration of the position of the stairs is performed in a similar manner. At this time, the number of people who can pass through each side of the mesh is set in advance in a part of the data of “passage / non-permission” of the route search mesh table 1200 (see the supplementary diagram * 5 in FIG. 17). A route can be searched.

Since the algorithm is general-purpose,
Evacuation exits and entrances are not only the entrances and exits of buildings, rooftop heliports, and any preset evacuation and intrusion locations, but also locations that change on the fly, such as where a ladder truck of a fire brigade extends a ladder. Can be dealt with simply by registering that location as an evacuation exit.

FIG. 23 shows an emergency exit 23-5 provided in advance.
Not only that, the fire brigade's ladder car can extend the ladder, and the intrusion window 23-6 can be added to the temporary emergency exit. In this case, a shorter evacuation route is found under the same conditions as in FIG. It becomes possible.

FIG. 24 is a diagram showing an example of searching for an intrusion route of the fire brigade. Step 160 of the detailed processing flow of FIG.
By applying the method 4, an intrusion route can be obtained in the same manner as in the evacuation route search.

Since there is a difference in equipment between the evacuees and the firefighters and other danger countermeasures, firefighters may be able to pass through places that are not accessible to evacuees, and evacuation routes and intrusion routes are generally different. It is likely to be something. In the unlikely event that they become the same, only in cases where the passage capacity is not possible, the routes of the fire brigade will be sorted to the second and third routes found by the maze method.

Returning to FIG. 4 of the overall processing flow, after an evacuation / intrusion route is found in step 408, the route is displayed and notified to evacuees and fire brigade in step 409.

As a method of notifying the calculated evacuation route and intrusion route, the display device 2011 shown in FIG. 2 is used. Since the position of each display is stored in advance in the external storage device 111 of the disaster prevention and rescue computer 10 together with its identification number, the display information based on the evacuation route is displayed for each display device together with the identification information and the route display control unit. 108. The display unit extracts only display information attached to its own identification information from the received display information, and performs display in accordance with the display information. The projection destination of display information such as an arrow is
It is possible to project not only on the passages and walls, but also on the smoke itself where the smoke is full.

In this case, it is conceivable that fine control such as distributing people who are in the same room to two routes to alleviate congestion cannot be performed.

Therefore, it is necessary to provide a method for issuing an instruction to the portable communication terminal 302 such as the IC card 307 or the portable telephone held by each person. As an example, an example using a mobile phone will be described with reference to FIG.

An antenna 2 is provided on the mobile phone main body 25-1.
5-2, a speaker 25-3, a microphone 25-4, a dial button 25-5, and a liquid crystal display 25-6 are provided. Here, considering a case where a route display is output to the liquid crystal display 25-6, as shown in the enlarged screen 25-6a, a method showing an arrow indicating a traveling direction and a traveling distance, and shown in an enlarged screen 25-6b. As described above, a method of expressing the instruction with characters can be considered. In addition, in consideration of the case where a person who is visually impaired or deaf is used, it is optimal to combine a method of giving a voice instruction from the speaker 25-3 as shown by 25-6c in addition to the above.

On the other hand, the portable information device possessed by the firefighting / emergency crew may be a mobile phone as shown in FIG. 25, but a more accurate situation such as a fire seen at the site is input to the disaster prevention and rescue computer 10. Considering this, a portable information terminal having a keyboard and a touch panel is desirable.

FIG. 26 is a diagram showing an example of the portable information terminal 26-1.
2, a keyboard 26-3, and a touch panel 26-4 used as a pointing device are provided on the operation surface. The layout diagram of the floor where the fire occurred is displayed on the liquid crystal display 26-2. On the layout, the current position, the fire place, the expected fire spread place of the firefighter carrying the personal digital assistant and the expected place are shown. The time, the intrusion route, and the emergency exit are displayed, and information such as the wind direction / wind speed is also displayed. Even in this case, of course, it is necessary to always report the current position of the fire brigade members. When registering an evacuation exit at a place where the ladder truck of the fire brigade extends the ladder, etc., on the spot, when registering from the operation panel 107 of the disaster prevention and rescue computer 10, and when carrying by the fire / rescue personnel Both registration from the portable information terminal 26-1 is possible. In the latter case, the location information is automatically transmitted simply by performing the registration operation on the portable information terminal at the place where registration is desired.

By the way, the fire brigade invades the target where the fire occurred, and the rescue crew invades the immobilized injured person. If considered injured, the path of entry for rescue personnel can be determined as well.

Steps 410 and 411 in FIG.
Corresponds to the processing. FIG. 27 shows a detailed flow of the rescue route search processing.

First, in step 2711, this process is executed only when there is an emergency or fire brigade member. Step 2
At 712, the rescue target person is additionally registered in the evacuee group at the same location unit, and at step 2713, the process is repeated only for each evacuee group added according to the guidance order. Before the rescue workers arrive at the evacuees at step 2714, a rescue route is searched from the location of the rescue target and the rescue workers according to the maze algorithm (step 2).
715) After arriving, the evacuation route is searched from the emergency exit and "the rescue target person + the location of the rescue squad" according to the maze algorithm (step 2716). Next, step 271
7, the obtained route is stored in the route management table 1300 (FIG. 1).
In step 2718, the obtained route is transmitted to and displayed on the portable information terminal 26-1 of the rescue worker, and the route is instructed.

FIG. 28 is a diagram showing a display example. Here, in addition to the intrusion route for rescue and the evacuation route after rescue, the current position and the location of the person to be rescued are displayed on the portable information terminal 2.
6-1 is displayed on the liquid crystal display 26-2.

Once the instruction has been completed for all the target groups (step 2719), the situation is checked each time the rescue personnel arrives at the location of the rescue target or when the evacuation is completed (step 2720, step 2720). 2
721) The display of the evacuation route is switched to the latest state as needed, and the evacuation of all the members is waited for (step 272).
2).

Finally, the process of creating fire equipment layout, traffic regulation, system interlocking information, etc., as required, and transmitting the equipment layout instruction, interlocking information, etc. (step 412 in FIG. 4) is described in detail in FIG. This will be described with reference to a detailed processing flow.

If there is the same system linked to the disaster prevention and rescue computer 10 (step 2901), the layout information inside the building, the information of the communication part (exit / emergency exit / passage) with the outside, the fire origin / scale information of the fire, the fire spread Information such as prediction information, weather information, firefighter personnel / equipment layout information, and evacuation guidance result information (which aisle is evacuated from which passage) is transmitted to another system (step 2902). That is, when the system shown in FIG. 1 is also installed in an adjacent building, the evacuation route calculation algorithm is the same, so that effective evacuation is realized while sharing information with each other. It can also solve the problem of who uses the access passage between buildings and how.

FIG. 30 shows an example. In FIG. 30, 30-1 is a building managed by system A, 30-2 is a building managed by system B, and 30-3 is both buildings A,
It is assumed that it is a shared passage of B. Now, in the building 30-1 managed by the system A, a fire occurs at the position indicated by 30-8, and the people in the building 30-1 are sorted by the system A according to the location, and two exits are provided. 30
Consider the case where the evacuation is divided into -4 and 30-5. Even in a building managed by the system B, it is desired to evacuate the people in the building into two exits 30-6 and 30-7.
-9 and information on the number of people 30-10 heading to the exit 30-5 are passed to the system B.
Considering the number of passable persons 0-3, the number of persons 30-11 to go to the exit 30-6 and the number of persons 30-12 to the exit 30-7 can be determined. Can be prevented from overflowing.

Next, in step 2903 of FIG. 29, if there is a public disaster prevention system such as a fire department or a local administrative organization, in step 2904, information on the origin / size of the fire, information on the influence of the fire on the outside of the building, The weather information around the building, firefighter personnel / ladder cars / fire trucks / ambulances, etc. placement result information, and information such as the number of evacuation guides / rescue targets are sent to the public disaster prevention system.

When the execution of the function for instructing the equipment arrangement of the fire brigade is instructed (step 2905), step 29
In step 06, the invasion route is calculated from the fire source and all of the fire brigade intrudable openings according to the maze method algorithm, taking into account the wind direction. In step 2907, the dispatch position of the ambulance closest to the guide destination exit of the rescue target is similarly calculated. It is calculated by the method. Then, the information on the ladder car entrance and the route to the fire source, the water discharge point and the fire engine position, the guidance destination exit of the rescue target, and the dispatch position of the ambulance are sent to the fire brigade portable information equipment or the direct fire brigade equipment placement instruction system. The call is transmitted and displayed (step 2908).

FIG. 31 shows an example of the display. In FIG. 31, equipment placement instructions such as a ladder truck, a fire truck, and an ambulance are displayed on the liquid crystal display 31-2 of the portable information terminal 31-1 of the equipment placement instruction system. In addition, 3 in FIG.
1-3 is a keyboard, 31-4 is a touch panel used as a pointing device.

In this way, it is possible to support local disaster prevention and rescue by instructing the equipment arrangement at the site.
For example, it is possible to instruct the location of a fire truck or a ladder truck or a point of fire extinguishing based on information on a fire occurrence location or a place where evacuees are present, which is difficult to understand from the outside, so that effective fire extinguishing / rescue activities can be performed.

In the case of a large-scale fire in which a fire spreads to a plurality of buildings or an entire area, the information transmitted in step 2904 in FIG. 29 is applied to each building in order to use limited rescue resources effectively. If you get together, effective measures will be taken. In addition, direct information from various detectors and information on evacuation routes and intrusion routes calculated from them are shared with multiple similar systems and public disaster prevention systems such as fire departments, police and local governments in charge of local disaster prevention. Linked to traffic regulations in the event of a disaster in a specific area under its jurisdiction,
Taking this into consideration, it is also possible to easily specify the dispatch destination of emergency vehicles such as fire trucks and ambulances and the route to arrival by utilizing the versatility of the route search algorithm.

As described above, according to this embodiment, based on information from a plurality of detectors installed in a building such as a building, fire, toxic gas, lack of oxygen, flooding, collapse, etc. Detect dangers, search for evacuation routes to safety areas or doorways, safely evacuate people inside, and indicate the route of entry for specialized danger personnel such as fire brigade and rescue teams, It can help prevent the spread of disasters effectively.

Note that the present invention is not limited to the above embodiment, and various necessary table configurations and data structures are appropriately changed in accordance with the functions of disaster prevention equipment and incidental equipment of a building. Can be implemented.

It is also possible to send an instruction to a self-propelled fire extinguishing robot instead of a fire brigade member to perform rescue or fire extinguishing activities.

Also, as a disaster prevention measure, a case of fire has been described as a representative. Even when a danger state such as flooding, toxic gas, or collapse occurs, an evacuation route and a rescue route are searched for and instructed by the same algorithm. be able to.

Further, by sequentially storing the state of expansion or contraction of the disaster in the external storage device, it is possible to effectively utilize the identification of the source of the fire (fire source) and the on-site verification of the state of expansion.

[0122]

As described above, according to the present invention, the following effects can be obtained.

(1) It is possible to provide optimal route information to disaster prevention countermeasures specialists who have rushed to fire fighting and rescue, and to support effective disaster prevention activities.

(2) Since the intrusion route followed by the specialist for disaster prevention measures is determined in consideration of the evacuation route, there is little interference with the path of the evacuees, and evacuation and rescue / disaster prevention activities are effectively realized. be able to.

(3) The evacuation route is determined by estimating the spread of a disaster at the time of evacuation based on the latest disaster information that changes moment by moment. Therefore, the evacuation route may become dangerous during evacuation. It is low and can be evacuated safely.

(4) Since the spread of disaster is predicted in consideration of weather conditions such as wind direction, wind speed, and temperature, it is unlikely that a dangerous evacuation route will be instructed.

(5) Since the operation information of the fireproof shutter, the waterproof door, and the like for preventing the spread of disaster is taken into consideration, the possibility that the designated evacuation route cannot be used is low.

(6) In order to rescue an injured person or the like who cannot move on their own, it is possible to indicate the invasion route of rescue workers.

(7) In searching for an evacuation route, all evacuation routes can be searched in a short time, even if the shape of a building or a passage is complicated or large. In addition, since it is not necessary to change the route search algorithm for each building and is versatile, information can be shared and linked between a plurality of systems.

(8) In selecting an evacuation destination, an evacuee can be immediately guided to an evacuation destination that can change on the spot, such as a place where a ladder car of a fire brigade extends a ladder, in addition to a preset candidate. .

(9) Since different evacuation routes can be instructed for each person, evacuees can be distributed and guided to a plurality of equivalent evacuation routes to prevent the capacity of the passage from being exceeded, or a wheelchair can be used. Detailed guidance such as showing evacuation routes to the user is possible.

(10) In cooperation with a public disaster prevention system such as a fire department or a police or a local government in charge of local disaster prevention, effective local disaster prevention can be performed even in the case of a wide-area disaster exceeding one building.
