  Next, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 shows an embodiment of a water force map creating apparatus 100 according to the present invention, which includes an input device 101 such as a keyboard, a data processing apparatus 102 operated by program control, It comprises a storage device 103 for storing information and an output device 104 such as a display device or a printing device.

  The storage device 103 stores a program executed by the data processing device 102 and stores map information 109 and water use information 110. The map information 109 is information that records a map of each part of the country. In this map information 109, the topography of the area, the size and position coordinates of a building already installed in the area, etc. are associated with the address of each place. Is recorded. Since the building is displayed as a plane on the map, it is preferable to use the center of gravity of the building as the position coordinate of the building. The irrigation information 110 is information that records the status of irrigation in various parts of the country. In this irrigation information 110, the location of the fire hydrant and waterproof layer installed in the area, the connection plug of the fire hose, and the address are associated with the address. Information indicating the caliber, water capacity, etc. is recorded.

  The data processing apparatus 102 is a CPU that performs various calculations, and generates a map display means 105 for displaying a map, an area selection means 106 for selecting an area where the water condition is desired, and statistical information indicating the water condition. Statistical information generating means 107, and statistical information display means 108 for displaying statistical information generated by the statistical information generating means 107.

  The map display means 105 searches the map information 109 in the storage device 103 based on the area or address designated via the input device 101 (hereinafter referred to as “area etc.”), and the map information of the designated area etc. And the map is displayed on the output device 104.

  The area selection unit 106 is for selecting an area for which statistical information is desired to be generated from the map displayed by the map display unit 105. The area can be specified by clicking or touching the area for which statistical information is desired on the map displayed on the output device 104, and the address of the area for which statistical information is desired is input. This is also possible.

  The statistical information generation unit 107 reads out the water use information of the area selected by the area selection unit 106 from the water use information 110 of the storage device 103, and calculates the distance from the buildings existing in the area to the water use. , Generate statistical information. The statistical information display means 108 superimposes and displays the statistical information generated by the statistical information generation means 107 on the map displayed on the output device 104, and creates a water rate map.

  Next, the operation of the water-rate map creation apparatus 100 in FIG. 1 will be described with reference to FIGS.

  When creating a water-use force map, first, an area to be displayed on the map is designated on the output device 104 via the input device 101, and map information on the designated region is read from the map information 109 in the storage device 103. (Step S1). For example, if A city B ward shown in FIG. 3 is designated as an address to be displayed on a map, the topographic information of A city B ward, and the size and position of buildings 200A to 200D and buildings 220A to 220C existing in the same area Coordinates and the like are read out.

  Next, a map of city A and city B is generated based on the read map information of city A and city B, and the generated map is displayed on the output device 104 (step S2). Next, a message requesting area selection is displayed on the output device 104, and an area for which statistical information is to be generated is selected via the area selection means 106 (step S3). Assuming that, for example, A city B ward 1-chome is selected as the area for which statistical information is to be calculated, statistical information generation processing is executed for buildings 200A to 200D existing in A city B ward 1-chome. (Step S4).

  In the statistical information generation process, as shown in FIG. 4, first, the water utilization information 110 in the storage device 103 is searched, and the water utilization information indicating the positions of the water utilization 210A and 210B installed in the A city B ward 1 chome. Is read (step S10). Next, one of the buildings 200A to 200D existing in A city B ward 1 chome is selected (step S11). This building may be selected from any of the buildings 200A to 200D. Here, for example, the building 200A is selected.

  Next, the position information of the selected building 200A is read from the map information 109 of the storage device 103 and output to the statistical information generation means 107 (step S12). Next, as shown in FIG. 5, the statistical information generating means 107 defines a circular range 240 having a radius Dest_a from the center of gravity position of the selected building 200A, and searches for water use existing in the range 240 (step S13). ).

  Next, the presence / absence of water supply is determined based on the result of the search process in step S13 (step S14). If there is no water supply, the value of the flag Flag_S indicating that there is no water supply is set to “1”. (Step S15).

  On the other hand, if water is present, it is determined whether or not there are a plurality of water within the circle range 240 (step S16). As shown in FIG. 5, when there are two water sources 210A and 210B, the distance Dest from the center of gravity of the building 200A to each water source is calculated for each of the water sources 210A and 210B (step S17). In calculating the distance Dest, the length of a straight line connecting the center of gravity of the building 200A to each water is calculated, and the length is set as the distance Dest. At that time, reference is also made to the terrain information of the A city and B ward recorded in the map information 109, and if there are ups and downs such as downhills from the building 200A to each water supply, follow the ups and downs. The lines may be connected and the length of the line may be the distance Dest. Here, for example, it is assumed that the distance Dest (A) from the center of gravity of the building 200A to the water use 210A is 100 m, and the distance Dest (B) from the center of gravity of the building 200A to the water use 210B is 200 m.

  Next, the shortest distance is identified from the calculated plurality of distances Dest and stored in the storage device 103 as the shortest distance Dest_t (step S18). Since the distance Dest (A) from the center of gravity of the building 200A to the water use 210A is the shortest distance, Dest (A) = 100 m is stored as the shortest distance Dest_t.

  On the other hand, when the number of irrigation waters within the circle range 240 is one, the distance from the center of gravity of the selected building to the irrigation water is calculated, and the calculated distance is the shortest distance Dest_t. Is stored in the storage device 103 (steps S19 and S20).

  When the flag processing in step S15 or the storage processing of the shortest distance Dest_t in steps S18 and S20 is completed, is there any other building that does not execute the processing in steps S12 to S20 in the area selected in step S3? It is determined whether or not (step S21). If there is still a building that has not been subjected to the processes of steps S12 to S20, one building is selected from the buildings, and the processes of steps S12 to S20 are performed in the same manner as described above. Thereby, the setting processing of the flag Flag_S or the storage processing of the shortest distance Dest_t is performed on the buildings 200B to 200D in the same manner as the building 200A. Thus, as shown in FIG. 6, the distance 150 m from the building 200B to the water use 210A and the distance 75m from the building 200C to the water use 210B are respectively calculated as the shortest distance Dest_t from each building to the water use, and stored in the storage device 103. The On the other hand, for the building 200D, since there is no water within the range of the radius Dest_a, the shortest distance is not recorded and the value of the flag Flag_S is set to “1”.

  When flag processing or storage processing of the shortest distance Dest_t is executed for all buildings existing in the selected area, the shortest distance Dest_t calculated for each building in the area is added, and a total distance Dest_j is calculated. (Step S23). In A city B ward 1-chome, since the shortest distances Dest_t of the buildings 200A to 200C are 100 m, 150 m, and 75 m, the total distance Dest_j is 325 m.

  Next, the calculated total distance Dest_j is divided by the number of buildings in the area, and an average distance Dest_ave from the building to water is calculated (step S24). Of the buildings 200A to 200D in the area, the buildings where water is present are the buildings 200A to 200C. Therefore, the composite distance Dest_ave = 325 m calculated in step S23 is divided by “3”, and the average distance Dest_ave is 108 m. Is calculated.

  Next, the calculated combined distance Dest_j and average distance Dest_ave are stored in the storage device 103 as statistical information.

  When the statistical information is generated, a statistical information display process is executed by the statistical information display unit 108 as shown in FIG. 2 (step S5). In the display process, as shown in FIG. 7, the calculated combined distance Dest_j and average distance Dest_ave are displayed so as to be superimposed on the map displayed on the output device 104. In addition, by selecting one of the buildings 200A to 200C, the route from the selected building to the nearby irrigation is displayed with an arrow line or the like, and the distance from the building to the irrigation is displayed near the arrow line or the like. The In addition, about the building 200D in which there is no irrigation, marking which shows that there is no irrigation is made, and it is displayed with the display mode different from other buildings 200A-200C.

  As described above, according to the present embodiment, the shortest distance Dest_t from each building in the area to the water is calculated, the average value Dest_ave is generated, and the output device is superimposed on the map of the area. Since it is displayed in 104, it is possible to grasp at a glance the density of water facilities for existing buildings in the area and whether water is installed in an optimal arrangement. Therefore, it is possible to easily grasp the water use situation, and it is possible to easily detect an area where the water use installation condition is insufficient.

  In addition, according to the present embodiment, for each building already established in the specified area, the shortest distance Dest_t to water is calculated for each building in units of buildings, and the total distance Dest_j and the average distance Dest_ave are calculated. Therefore, it is possible to create a water-use force map that accurately reflects the water-use situation in the area.

  Furthermore, according to the present embodiment, when a plurality of irrigation water is installed in the area, the distance Dest from each building to each of the plurality of irrigation waters is calculated, and the shortest distance Dest_t is calculated from the calculated distance Dest. Since the statistical information is generated by identifying the water, it is possible to create a water-rate map suitable for actual fire fighting activities.

  In addition, according to the present embodiment, it is determined whether or not water is present within a certain distance Dest_a from the building. For buildings where there is no water, marking or the like is performed to determine whether water is present or not. Since it is displayed in a different display mode, it becomes possible to easily grasp a building with insufficient water installation.

  FIG. 8 shows a second embodiment of the water-rate map creating apparatus according to the present invention. In FIG. 8, the same components as those in the water-rate map creating apparatus 100 in FIG.

  As shown in the figure, the water-use-and-force map creating apparatus 300 includes an input device 101, a data processing device 102, and a storage device 103. The storage device 103 includes map information 109, water use information 110, and road information 301. Is stored, and the data processing apparatus 102 is provided with a map display means 105, an area selection means 106, a statistical information generation means 302, and a statistical information display means 108.

  The road information 301 is information in which road conditions in various parts of the country are recorded. In the road information 301, information indicating road routes, road widths, and the like in the area is recorded in association with addresses. When calculating the distance from the building to the water use, the statistical information generating unit 302 specifies the position of the building and the water use based on the map information 109 and the water use information 110 and also uses the water information from the building based on the road information 301. The route from the building to the irrigation when moving along the road is calculated.

  Next, a case where statistical information is generated using the water / wage force diagram creating apparatus 300 of FIG. 8 will be described with reference to FIGS. 9 and 10. 9 and 10, the same components as those in FIGS. 3 to 7 are denoted by the same reference numerals, and the same processes are denoted by the same step numbers.

  When an area for which statistical information is to be generated is selected via the area selection means 106, as shown in FIG. 9, a irrigation information reading process, a building selection process, and a determination process for determining the presence or absence of irrigation are performed ( Steps S11 to S14). If there are water irrigations, it is determined whether or not there are a plurality of water irrigations (step S16). If there are a plurality of water irrigations, the center of gravity position of the buildings and the water irrigation are linear for all buildings. The most recent distance Dest that is connected is calculated (step S17).

  Next, it is determined whether or not the calculated distance Dest is equal to or less than a predetermined distance Dest_n (step S31). When the distance is less than or equal to the distance Dest_n, the shortest distance is searched from the calculated distance Dest and stored in the storage device 103 as the shortest distance Dest_t.

  On the other hand, when the calculated distance Dest is larger than the predetermined distance Dest_n, the road information 301 is referred to, and a route from the center of gravity position of the selected building to water is searched (step S32). Next, as shown in FIG. 10, the distance 310 from the building to the road, the distance 311 from the water to the road, and the road length 312 are respectively calculated and added to calculate the distance Dest_r (step S33). . Thereafter, the shortest distance is retrieved from the calculated Dest_r and stored in the storage device 103 as the shortest distance Dest_t.

  Further, even when the number of irrigation waters is one, it is determined whether or not the calculated distance Dest is equal to or smaller than the predetermined distance Dest_n (step S34). The distance Dest_r is calculated based on 301 (steps S35 and S36).

  Here, when the calculated distance Dest is equal to or less than the predetermined distance Dest_n, the distance Dest_r when using the road is not calculated if the distance from the building to the water supply is short even if the road is not used. This is because there is a high possibility that fire fighting activities can be performed. That is, if the distance from the fire site to the fire hydrant etc. is short, the fire hose can be transported to the water without using the road, and the fire hose connected to the fire hydrant etc. may reach the fire site. In such a case, it is more effective to specify the straight distance to the irrigation than to specify the distance when using the road, so if the irrigation is installed near the building, The shortest distance Dest_t is specified by using the nearest distance Dest connecting the center of gravity of the building and the water supply with a straight line.

  When the shortest distance Dest_t is calculated, the calculation process of the shortest distance Dest_t is performed for other buildings as well as in FIG. 4, and the total distance Dest_j and the average distance Dest_ave are calculated to generate statistical information. (Steps S21 to S24).

  According to the present embodiment, the route from the center of gravity position of the building to the irrigation is searched based on the road information 301, the distance Dest_r when the road is moved is calculated, and the shortest distance is calculated using the calculated distance Dest_r. Since the distance Dest_t is calculated, it is possible to accurately calculate the travel distance required when actually performing the fire fighting activity, and it is possible to create a water-power map suitable for the actual fire fighting activity.

  In addition, according to the present embodiment, when the distance Dest from the building to the water is less than or equal to the predetermined distance Dest_n, the route search is not performed, and the distance Dest on the straight line connecting the center of gravity of the building to the water is calculated. In order to calculate the shortest distance Dest_t, it is possible to create a water force map suitable for actual fire fighting activities.

  The embodiment of the present invention has been described above, but the present invention is not limited to the above-described configuration, and various modifications can be made within the scope of the invention described in the claims.

  For example, in the above-described embodiment, the distance Dest with water irrigation is calculated for all buildings existing in the specified area. However, in the area where the buildings in the area are densely packed, it is not always necessary for each building. It is not necessary to calculate the distance Dest. When there is such a section, for example, a portion where buildings are densely considered is regarded as one building, and the distance from the center position of the portion to the water use may be set as the distance Dest.

  In the above embodiment, both the total distance Dest_j and the average distance Dest_ave are displayed on the output device 104. However, it is not always necessary to display both of them, and only the average distance Dest_ave may be displayed. .
