Description

  The present invention relates to an emergency dispatch command system installed in a fire department or the like, and more particularly to a display form of water use information in a map search device that searches and outputs a map around a site.

Conventionally, a fire fighting command system, which is one of emergency dispatch command systems, is configured as shown in a block diagram in FIG. 15, for example.
The function and operation will be described with reference to FIG. The headquarter apparatus includes a command board 1, an automatic dispatch designation apparatus 2, a map search apparatus 80, and a command transmission transmission apparatus 4, and is connected to each other by, for example, a LAN (local area network). Yes.

  The command board 1 provided in the headquarter apparatus receives an emergency call 1a such as a 119 call, and the operator calls the caller and confirms the content of the call. In the automatic dispatch specifying device 2, the operator sequentially inputs the contents of the emergency call 1a, for example, the address and status of the site using an input device (not shown) such as a mouse or a touch panel. The command stand 1 and the automatic dispatch specifying device 2 constitute command means.

  The automatic dispatch designation device 2 automatically designates an emergency dispatch vehicle, for example, an ambulance, a fire engine, etc., based on the contents of the input report, and a map around the site retrieved by the map retrieval device 80. The data is received and a command sheet is created, and a map around the site is displayed on a display device (not shown) provided in the automatic dispatch specification device 2.

  The map retrieval device 80 receives the data of the contents of the report input to the automatic dispatch specification device 2, searches the map including the emergency occurrence point based on this, and outputs the retrieved map data to the automatic dispatch specification device 2. . The command transmission transmission device 4 generates transmission data from the command document and the map and transmits the transmission data to the station device, and also transmits the notice command by voice synthesis and the voice data of this command to the station device.

  The station terminal device 5 provided in the station device is connected to the headquarters device, for example, via the dedicated line network 7, receives the transmission data transmitted by the command transmission transmission device 4, restores the instruction document and the map, The screen display data is generated, and the audio data is restored and output as audio. The display device 5a connected to the station terminal device 5 displays screen display data. Then, the command transmission output device 6 connected to the station terminal device 5 prints out the command document and the map.

  Such a station terminal device 5 is connected to the above-mentioned head office device and at least one station device to form an emergency dispatch command system (see, for example, Patent Document 1).

  FIG. 16 shows an example of a command document output from the command transmission output device 6, focusing on a disaster site represented by a mark composed of a double circle and a crosshair, such as a fire hydrant and a fire prevention water tank around the disaster site. The location of irrigation and road closure due to road construction are listed on the map, making it easy to grasp the location of irrigation that is close to the site and that can be reached by a fire engine.

However, the location of irrigation on the map is a layout in a plane.For example, even if the fire hydrant closest to the scene is listed, the actual fire spot is on a high ground, and the nearest fire hydrant is located in a low ground. It may exist. Therefore, a sufficient amount of water could not be secured due to this height difference, and as a result, another fire hydrant on a hill far from the fire site might be effective for actual fire fighting activities.
In this way, it may not be possible to select water conservancy simply by the distance on the map, and in the fire department that issues a directive, when actually using it at the fire site from among the multiple water sources existing around the fire site There is a demand for the construction of an emergency dispatch command system that can generate a map for selecting effective water use.

JP 2002-245580 A (page 3-4, FIG. 1)

  The present invention solves the above-mentioned problems, and an emergency dispatch command that can generate a map for selecting effective irrigation water when actually used at a fire site from among a plurality of water sources existing around the fire site The purpose is to provide a system.

In order to solve the above-mentioned problems, the present invention accepts a report including an address of the site and converts it into data, and outputs a command for responding to the report, and the site converted into data by the command unit In an emergency dispatch command system comprising a map retrieval device that obtains address data and outputs map data corresponding to the site address to the command means, the map retrieval device uses a predetermined map area as image data. Storage device for storing converted map image data, status data obtained by quantifying the degree of obstacles to fire extinguishing and the ability of water use as weight data, and a map around the site corresponding to the site address from the map image data a map search means for searching and outputting, to create a water use landscape representing the forces of irrigation, and a water supply landscape generating means for outputting to said command means, said irrigation landscape work The means acquires map data around the site from the map search means, calculates an elevation difference based on the elevation of the fire site from the acquired map data, and adds the calculated elevation difference to the numerical value of the situation data Thus, a water force map representing the water force existing around the site is created.

Without considering the simple distance between the fire site and the fire hydrant, it is possible to select a water effluent such as a fire hydrant that is highly effective in consideration of the fire extinguishing work, that is, has good workability and is suitable for use. In addition, even when preventive water discharge is performed around the fire site, it is possible to select the optimal water supply at that location.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described in detail as examples based on the attached drawings. The feature of the present invention is to generate a water-use force map (map data) for selecting effective water-use when actually used from a plurality of water-uses existing around the fire site. The difference from the technology is only the processing method of the map search device of the fire fighting command system of FIG. 15 described in the background art section, and the functions of the other devices are not changed in the case of the present invention.
Accordingly, the map retrieval apparatus according to the present invention is given the number 3 instead of the conventional number 80, and the same numbers are assigned to the other devices, and detailed description is omitted.

  FIG. 1 is a block diagram showing a map retrieval apparatus 3 according to the present invention. The map retrieval device 3 includes a storage device 31 that stores map image data obtained by dividing a predetermined area under the jurisdiction of a fire department into a plurality of pages, irrigation situation data representing the current state of irrigation, and fire fighting activities such as roads and buildings A storage device 32 for storing failure status data, which is information that causes failure, and a map search means 33 for searching and outputting a map around the site corresponding to the address of the fire site input via the LAN from map image data, , A map of the vicinity of the site output from the map search means 33 is input, and a water rate map representing water rates advantageous for use at the site using the water status data and fault status data stored in the storage device 32. Is generated and sent to the LAN via the map search means 33, while the water supply status is updated based on the change data input from the console 34, and the water supply status data and the fault status data are updated. And FIG creating means 35, and a display unit 36 for displaying data from the irrigation landscape creating means 35.

Next, the operation of the map search apparatus 3 will be described. FIG. 2 is an explanatory diagram showing the structure of each stored data.
As shown in FIG. 2C, the map image data stored in the storage device 31 includes the segmented image data, the position coordinates of the image data with respect to the entire map, and the altitude of the place represented by the image data ( (Unit: meter) is composed of one set, and a plurality of such sets are stored. A section represented by a set of coordinates (x, y) is called a mesh and is the minimum unit of map image data.

  The map search means 33 converts the address data of the fire site input via the LAN into position coordinates, searches the map around the site corresponding to the position coordinates from the map image data, for example, the map image of FIG. Extract. This map image represents the range of one page, and is configured by connecting 12 meshes.

  In addition, status data of water use status and fault status is managed in units of meshes. The irrigation situation represents the capacity of the relevant irrigation water. The location (position coordinates) of irrigation water, such as a fire hydrant, fire prevention water tank, and a river where water can be used, and the connection plug for connecting a fire engine hose to the irrigation water The diameter (mm) and the number of pipes which are the number of connection plugs are shown. For example, the irrigation status data in FIG. 2 (A) stores all the irrigation status data managed by the firefighting headquarters. The position coordinates of the fire hydrants 113 to 115 shown in FIG. Each of the numbers of pipes stores the values shown in the figure.

On the other hand, the failure status is information that becomes an obstacle to fire fighting activities such as road works and large buildings. For example, as shown in the failure status data of FIG. The degree of failure given to is stored numerically. The degree of failure is defined as “0” when there is no trouble in the work, a negative value when the trouble occurs, and a negative value that increases as the work becomes difficult. The degree of disability is calculated by the fire department staff by quantifying various report information submitted to the fire department or city hall, information obtained from the patrol by the fire department staff, and the fault status data is updated sequentially. In addition, the irrigation situation data is updated in the same manner if there is a change.
In this way, detailed situations can be digitized (weights described later), and the situation data can be stored and managed as a data table in the storage device 32, so that an accurate water / weather force map can be created.

  The water use status and the failure status are always updated to the latest information by the fire department staff, and are input from the console 34 by manual operation of an operator (not shown) according to the control of the water force map creating means 35 in FIG. After the confirmation by the operator, each status data in the storage device 32 is updated.

  In this way, when a fire occurrence notification is entered in the fire fighting command system in which each data is stored, the command stand 1 provided in the headquarters apparatus confirms the content of the report by the operator calling with the reporter. To the automatic dispatch specification device 2, the operator sequentially inputs the contents of the report, for example, the address and status of the site.

  Then, the automatic dispatch specifying device 2 outputs the reported address as on-site address data to the map retrieval device 3 via the LAN. In the map retrieval apparatus 3, the site address data is converted into site position coordinate data corresponding to the map image data, for example, position coordinates (502, 801) using, for example, a conversion table, and the map image data is used with the site position coordinates as a key. And a map around the fire site (position coordinates indicating a plurality of meshes) is extracted. A map around the fire site is shown in FIG.

  Then, the map retrieval device 3 delivers a map around the fire site to the water-use force diagram creating means 35. The map data around the fire site includes altitude data for each position coordinate (mesh) as shown by the map image data in FIG. This altitude data is very important for fire fighting activities.For example, if there is a large difference in altitude between the fire hydrant installed in the lowland and the fire site in the highland, the water pressure required for water discharge cannot be obtained. Insufficient fire fighting may not be possible.

  For this reason, in the present invention, when creating a water force map, first, altitude difference data is extracted for each mesh in the map page with reference to the altitude of the fire site. Specifically, in the map image data of FIG. 2 (C), it corresponds to the mesh in the page, that is, the position coordinates in the page, based on the fire occurrence site, that is, the altitude of 50 m of the site position coordinates (502, 801). The difference from the altitude to be calculated is calculated. For example, it can be calculated that the mesh in which the fire hydrant 114 is present has an altitude of 40 m in position coordinates (503, 802) and is −10 m from the fire site. FIG. 4 shows the calculated altitude difference between the meshes in the page, and the positions of the meshes correspond to those in FIG. In addition, if the elevation difference becomes positive, high water pressure is obtained, which means that it is advantageous for fire fighting activities.

  Referring to FIG. 4, the position coordinates (502, 802) and the position coordinates (503, 802) have a large negative elevation difference, and the XXX district surrounded by the road A and the road B shown in FIG. ○○ It can be seen that it is located under the cliff beside the building (not appearing on the map image).

In the present invention, as shown in FIG. 4, a numerical value for each mesh necessary for creating a water force map is referred to as “weight”. When this weight is a small value, for example, when the above-described elevation difference is −10, the weight is small, and therefore, fire fighting activity is hindered, and as a result, it can be determined that the water-use power of the fire hydrant 114 is weak.
As described above, according to the present invention, the weight for each mesh is calculated based on the altitude difference data and the failure status data, and the calculated weight is integrated for each mesh to quantify the elements that hinder fire fighting activities.

  Next, a method for calculating the building failure weight data will be described. In fire fighting activities, private houses usually do not become an obstacle, but large buildings and the like need to bypass a fire hose, which is an obstacle depending on the size and shape of the building. For this reason, as shown in FIG. 2B, in the failure status data, when there is a building that becomes a failure in the position coordinates corresponding to the large building failure, weight data is stored as the degree of failure. FIG. 5 shows the result of extracting only the data in the page.

  The position coordinates (501, 800) and the position coordinates (502, 800) have a U-shaped building, and the fire hydrant 113 is arranged so as to be surrounded by this, so the degree of failure is relatively large ( Small weight). Further, it can be read that there are large buildings in the position coordinates (501, 801) and the position coordinates (501, 802), which are a little obstacle.

  Similarly, FIG. 6 shows the result of calculating the road construction fault using the fault status data of FIG. It can be seen that the road B at the position coordinates (502, 802) is currently under construction. During construction, it is difficult for a fire engine or fire hose to cross or traverse this mesh area, and the degree of failure increases (weight decreases).

  FIG. 7 is a diagram showing the calculation process of the weight data in consideration of the weight due to the above-described altitude difference, the weight due to the building failure, and the weight due to the road failure. Three numerical values delimited by commas described in each mesh represent the weight of the altitude difference, the building obstacle, and the road obstacle from the left. Therefore, the total value obtained by adding the numerical values of these three weights represents the degree of failure in the mesh, and the numerical value is described below the mesh.

  Next, the weight of the fire hydrant will be described. The weight of the fire hydrant is determined by the diameter and the number (number of pipes) of the connection plug for the fire hose provided therein. In other words, the larger the aperture, the higher the fire extinguishing capability, and the smaller the aperture, the smaller the flow rate and the lower the extinguishing capability. In this embodiment, when the aperture is 70 mm, the weight is defined as 20, and on the basis of this, the different aperture determines the weight according to the ratio.

  For example, as shown in FIG. 8, the fire hydrant 114 has a diameter of 70 mm and a weight of 20, but the fire hydrant 113 has a diameter of 75 mm. Therefore, the weight ratio of 1.07 is multiplied by the weight 20 and the weight is 21.4. Become. Similarly, since the fire hydrant 115 has a diameter of 60 mm, the weight 20 is multiplied by the weight ratio 0.86 and the weight becomes 17.2. In this embodiment, the number of connection plugs is 1 as shown in FIG. If there are two ports like the fire hydrant 116, the weight of the fire hydrant may be multiplied by the number of pipes.

Next, a method for calculating the effectiveness of the fire hydrant in the fire hydrant 115 for each mesh will be described.
The effectiveness of a fire hydrant is determined by its ability, that is, the weight of the hydrant described above, the location of the hydrant and the location of the fire site. That is, workability and water pressure decrease as the distance from the fire hydrant decreases, and workability and water pressure also decrease if there are obstacles or height differences on the way. Accordingly, in the present invention, the result of calculating the weight for each mesh in consideration of these is referred to as a power value, and a diagram representing this power value for each mesh is referred to as a distribution diagram.

  Specifically, paying attention to one fire hydrant, here the fire hydrant 115, this is defined as the start position of the power value, and in this embodiment, the mesh at this start position is referred to as a water utilization mesh. Then, the adjacent meshes diagonally forward / backward and left / right from the irrigation mesh subtract 5 as a weight from the irrigation mesh in order to count the decrease in workability and water pressure as a decrease in weight (in this description, to add -5 )

  Further, since each mesh has the various obstacles described above, the weight data of FIG. In this way, the power value is calculated with the mesh around the water utilization mesh, and then the next mesh is calculated based on the calculated power value. Note that the mesh to be calculated is specified in a radial manner based on the water utilization mesh. In addition, the arrow over a mesh has shown the advancing direction of calculation.

  FIG. 9 is a distribution diagram of the result of calculating the power value of the fire hydrant 115. Three numerical values separated by commas from the left are the weight of the previous mesh, the weight due to mesh movement, and the failure of the corresponding mesh. The total values of the weights are respectively represented, and the result of adding these is the power value in the mesh. However, since there is no previous mesh in the irrigation mesh, the weight of the fire hydrant is replaced with the weight of the previous mesh.

  Similarly, FIG. 10 shows a distribution diagram of the result of calculating the power value of the fire hydrant 113, and FIG. 11 shows a distribution diagram of the result of calculating the power value of the fire hydrant 114. Then, the power values of the corresponding meshes in FIGS. 9 to 11 are individually compared, and the figure having the greatest weight, that is, the fire hydrant is the power of the mesh. For example, looking at the position coordinates (503, 800), in FIG. 9, the power value is 0.2, FIG. 10 is 4.4, and FIG. 11 is 0. FIG. 10, that is, the fire hydrant 113 has the most power. It can be read that it is big. In this manner, the power of each fire hydrant overlapped with the map data is the water force map shown in FIG.

  In FIG. 12, the position coordinates (502,800) and the position coordinates (503,800) are the power range of the fire hydrant 113, and the position coordinates (503,801) and the position coordinates (503,802) are the power range of the fire hydrant 114. It can be seen that other meshes are within the power range of the fire hydrant 115. In other words, when performing fire extinguishing work on the XX building, the fire hydrant 115 which is not the nearest fire hydrant 113 among the three fire hydrants and is not the next fire hydrant 114 closest to the work site is used. It can be read that it is most effective to do.

  Therefore, as shown in FIG. 12, the power range of each fire hydrant is shown on a map, so that it is highly effective when fire fighting activities are started in consideration of workability in fire fighting without being constrained by the simple distance between the fire site and the fire hydrant. A fire hydrant (good workability) can be selected. Even when preventive water discharge is performed around the fire site, an optimal fire hydrant can be selected to discharge water at that place (mesh).

  In addition, the water tide map creation means creates a mesh distribution map for each of a plurality of irrigation with different meshes, and uses the irrigation force value at the mesh corresponding to the site in the created mesh distribution map for each water irrigation. By selecting the priority for multiple irrigation waters, creating a water tide map with the same priority and corresponding markings, you can select the irrigation water to be used when using multiple irrigation waters in combination. It can be done easily.

  For example, in FIGS. 9 to 11, when attention is paid to the position coordinates (502, 801) that are the fire site, the power value is 5.2 in FIG. 9, 4.4 in FIG. 10, and 5.0 in FIG. Thus, the priority order of the fire hydrant used at the fire site is the order of fire hydrant 115> fire hydrant 114> fire hydrant 113. Therefore, if a fire hydrant to be used is selected in addition to the fire hydrant 115, the fire hydrant 114 is optimal. For this reason, (1) to (3) representing the priority order are marked on the side of each fire hydrant in the water force map of FIG.

Although not shown in the figure, the water-use force map creation means compares the force value in the mesh with a predetermined reference value of the fire extinguishing ability, and the water use in which the corresponding mesh is marked corresponding to the comparison result. A power map may be created.
For example, if the mesh with sufficient power for fire fighting work is green, if the power is not enough, turn it to yellow, and if it is not enough, turn it red. It is possible to quickly determine whether a fire hydrant can be extinguished alone or whether another fire hydrant is necessary.

  Specifically, the power value of the fire extinguishing ability sufficient for the fire extinguishing work is set in advance as 14 (green), and the minimum necessary power value is set as 10 (yellow) as a reference value of the fire extinguishing capacity. Then, in FIG. 9, the mesh of the position coordinates (500, 801) is 17.2 and larger than the reference value of 14, so the color is green. The mesh of the position coordinates (501, 801) is 10.2, and the reference value of 10 Since the mesh of the position coordinates (502, 801) is 5.2, which is smaller than the reference value of 10, for example, it is marked red.

  Referring to this, it is understood that the fire hydrant 115 has the largest power with respect to the position coordinates (502, 801), which is the fire site, in the fire hydrant of this example, but the fire hydrant alone cannot perform a sufficient fire fighting activity. Therefore, when another fire hydrant, for example, the fire hydrant 114 and then the fire hydrant 113 are sequentially used in accordance with the above-described priority order, the power value of the position coordinates (502, 801) at the fire site of this fire hydrant is 14.6 in total. It can be seen that sufficient fire extinguishing activity can be achieved by using three fire hydrants in combination.

  In this way, the water / weather force map creating means 35 creates the water / weather force map shown in FIG. 12 and sends this water / weather force map data to the LAN via the map search means 33. The automatic dispatch designation device 2 that has received this water / wet power map data automatically designates an emergency dispatch vehicle, for example, an ambulance, a fire engine, etc., based on the contents of the report, and the site created by the map retrieval device 3 The peripheral water-rate map data is received and a command sheet is created, and the water-rate map is displayed on a display device (not shown) provided in the automatic dispatch specification device 2.

  Then, the command transmission transmitting device 4 generates a command document and a water-rate map as transmission data and transmits it to the station device, and also transmits a notice command by voice synthesis and voice data of this command to the station device. The station apparatus displays the water force map on the display device 5a, and prints out a command document on which the water force map is printed from the command transmission output device 6. The dispatched emergency vehicle carries this directive, so it can make quick and accurate judgments regarding the use of water at the fire site.

Next, the map search process in the map search means will be described based on the flowchart of FIG.
In the map search process, first, LAN data is monitored, and reception of field address data from the LAN is confirmed (ST1). If no site address data has been received (ST1-N), a map transmission request from the water force map creating means is confirmed (ST2). If there is no map transmission request (ST2-N), the process jumps to ST1.
If there is a map transmission request (ST2-Y), the data on the water rate map is received from the water rate map creating means and is output to the LAN (ST3). Then, jump to ST1.

  On the other hand, if the site address data is received (ST1-Y), the map page corresponding to the site address is retrieved from the map image data, and the data on this page is handed over to the water rate map creating means to create the water rate map. A request is made (ST4). Then, jump to ST1.

  Next, water interest map creation processing in the water interest map creation means will be described based on the flowchart of FIG. In the water interest map creation process, first, it is confirmed whether each failure data is updated (ST10). If it is not update of each trouble data (ST10-N), it will be confirmed whether it is a water-rate map creation request (ST11), and if it is not a water-rate map creation request (ST11-N), it will jump to ST10.

  If the request is to create a water force map (ST11-Y), the altitude difference data is calculated using the altitude data of the map image data (ST12), the building obstacle weight data is extracted (ST13), and then the road obstacle The weight data is extracted (ST14), the weight data for each mesh is calculated (ST15), the weight data for the fire hydrant is calculated (ST16), and the water force value is calculated for each fire hydrant (ST16). (ST17) Next, a water rate map of each fire hydrant is created (ST18), and data of the water rate map is sent to the map retrieval means, and a transmission request to the LAN is made (ST19). Then, the process jumps to ST10.

  On the other hand, if each failure data is updated (ST10-Y), the update data is input from the console (ST20), and then the water supply status data or the failure status data is updated according to the update data (ST21). Then, the process jumps to ST10.

  As described above, when creating a water rate map, a simple calculation repetitive operation may be performed, so that it becomes easy to design a water rate map creation program. Further, since the amount of work for creating the water force map can be adjusted depending on the size of the mesh, it is possible to set the work amount optimal for the ability of the computer that executes the water force map drawing program.
