Problems to be Solved by the Invention

[0004] Since the requirements for the arrangement of fire hydrants change constantly depending on the circumstances specific to the installation location and the regulations to be complied with, it is required to simply evaluate the arrangement state (arrangement position, number of arrangements, etc.) of fire hydrants.

[0005] One aspect of the present invention aims to realize an evaluation device or the like that can simply evaluate the arrangement state of fire hydrants.

[0007] Furthermore, an evaluation method according to one aspect of the present invention is an evaluation method performed by a computer to evaluate the arrangement of a plurality of fire hydrants in a pipeline, and includes: a designation processing step of designating a reference point in a pipeline diagram showing the pipeline; a grouping processing step of performing grouping of a plurality of fire hydrants located within a predetermined range from the reference point into the same group; a hydraulic analysis step of performing hydraulic analysis for each of the grouped plurality of fire hydrants; and a calculation step of calculating the drainage capacity of the grouped plurality of fire hydrants based on the hydraulic analysis results obtained in the hydraulic analysis step.

[Effects of the Invention]

[0009] According to one aspect of the present invention, an evaluation device that can easily evaluate the arrangement of fire hydrants can be realized. [Brief explanation of the drawing]

[0010] [Figure 1]This is a block diagram showing the configuration of the main parts of an evaluation device according to an embodiment of the present invention. [Figure 2] This figure shows an example of the search range used by the grouping processing unit to find fire hydrants to be grouped. [Figure 3] This figure shows an example of the display of the number of bottles that can be opened by the display processing unit. [Figure 4] This flowchart shows an example of an evaluation method. [Modes for carrying out the invention]

[0011] Embodiments of the present invention will be described in detail below.

[0012] Figure 1 is a block diagram showing the configuration of the main parts of an evaluation device 1 according to an embodiment of the present invention. The evaluation device 1 evaluates the arrangement of multiple fire hydrants in a pipeline. As shown in Figure 1, the evaluation device 1 comprises a calculation unit 10, a display unit 20, an input unit 30, and a storage unit 40.

[0013] The calculation unit 10 performs calculations to evaluate the arrangement of multiple fire hydrants in a pipeline. The calculation unit 10 includes a designation processing unit 11, a grouping processing unit 12, a hydraulic analysis unit 13, a calculation processing unit 14, a display processing unit 15, a judgment unit 16, and an optimization processing unit 17.

[0014] The designation processing unit 11 performs a designation process to specify a reference point in a pipeline diagram showing pipelines. For example, the designation processing unit 11 accepts input from the user to specify a reference point and specifies the reference point based on that input. The reference point is, for example, a water meter or a fire hydrant. In this case, the water meter is the reference point corresponding to the house or other building that has the water meter.

[0015] The grouping processing unit 12 performs grouping, which groups multiple fire hydrants located within a predetermined range from a reference point into a single group. The predetermined range is, for example, a circle centered on the reference point with a radius equal to the search distance entered by the user. Furthermore, the predetermined range is not limited to a circle, and may be a rectangle circumscribing the circle with a radius equal to the search distance entered by the user.

[0016] Figure 2 shows an example of the search range used by the grouping processing unit 12 to search for fire hydrants to be grouped. In Figure 2, areas outside the search range are shaded. In the example shown in Figure 2, the coordinates of the reference point P are (x,y). The predetermined range is defined as the area centered on the reference point P with a radius of the search distance L. In this case, the grouping processing unit 12 defines the search range as the area from xL to x+L in the X direction and from yL to y+L in the Y direction, and excludes all other areas from the search range. By limiting the search range in this way, the grouping processing unit 12 can reduce the number of fire hydrants to search and improve the efficiency of the processing.

[0017] The grouping processing unit 12 may group all fire hydrants located within a predetermined range from a reference point into the same group. Alternatively, the grouping processing unit 12 may group up to a predetermined number of fire hydrants located within a predetermined range from the reference point into the same group. In the latter case, after searching for fire hydrants located within a predetermined range from the reference point, the grouping processing unit 12 may group a specified number of fire hydrants in order of proximity to the reference point. In this case, the predetermined number is specified by the grouping processing unit 12, for example, based on user input.

[0018] The grouping processing unit 12 groups the fire hydrants and then creates a list of the number of grouped fire hydrants for each reference point. This list includes information for identifying the reference point and the number of fire hydrants grouped at that reference point. The information for identifying the reference point is, for example, an identification number assigned to the water meter or fire hydrant used as the reference point.

[0019] The hydraulic analysis unit 13 performs hydraulic analysis for each of the grouped plurality of fire hydrants. Specifically, the hydraulic analysis unit 13 performs hydraulic analysis based on the fire extinguishing water volume per hydrant and calculates the water pressure at the hydraulic connection point. The hydraulic connection point refers to the intersection of pipelines, valves, fire hydrants, etc. The hydraulic connection points for which the hydraulic analysis unit 13 calculates the water pressure are predetermined in the pipeline network.

[0020] The fire extinguishing water volume per hydrant is, for example, a value specified by the hydraulic analysis unit 13 based on an input from the user. The fire extinguishing water volume per hydrant is the water volume required for fire extinguishing. Usually, the fire extinguishing water volume per hydrant is 1 m 3 per minute. However, the fire extinguishing water volume per hydrant may be changed to, for example, 0.5 m 3 per minute if it is considered difficult to obtain sufficient water volume for fire extinguishing from the fire hydrant.

[0021] Based on the hydraulic analysis result by the hydraulic analysis unit 13, the calculation processing unit 14 calculates the drainage capacity of the grouped plurality of fire hydrants for the grouped plurality of fire hydrants. The drainage capacity of the plurality of fire hydrants is the overall drainage capacity of the grouped plurality of fire hydrants. The drainage capacity of the plurality of fire hydrants varies according to the arrangement state such as the number and position of the plurality of fire hydrants. In the evaluation device 1, since the calculation processing unit 14 automatically calculates the drainage capacity based on the water pressure determination criterion, the arrangement state of the fire hydrants can be easily evaluated.

[0022] The drainage capacity calculated by the calculation processing unit 14 may be the number of fire hydrants that can be opened in the grouped plurality of fire hydrants. The number of fire hydrants that can be opened is the number of fire hydrants that can be opened, that is, among the grouped plurality of fire hydrants, the number of fire hydrants whose water pressure is above the water pressure determination criterion. The water pressure determination criterion is, for example, a value set by the calculation processing unit 14 based on an input from the user. In this case, in the evaluation device 1, since the calculation processing unit 14 automatically calculates the number of fire hydrants that can be opened based on the water pressure determination criterion, the arrangement state of the fire hydrants can be easily evaluated.

[0023] Another example of drainage capacity is the total drainage volume of a group of fire hydrants, or the number of fire hydrants within the group. In the following explanation, it is assumed that the drainage capacity calculated by the calculation processing unit 14 is the number of hydrants that can be opened.

[0024] Specifically, the calculation processing unit 14 calculates the minimum water pressure at the hydraulic junction for each of the fire hydrants grouped at each reference point. Then, the calculation processing unit 14 determines that fire hydrants whose minimum water pressure at the hydraulic junction is equal to or greater than the water pressure judgment standard can be opened, and calculates the number of openable fire hydrants as the number of openable fire hydrants at the reference point.

[0025] Furthermore, the calculation processing unit 14 creates a list of fire hydrants in the group whose minimum water pressure at the hydraulic junction did not meet the water pressure criteria. This list includes information for identifying the hydraulic junction of the pipeline connected to each fire hydrant in the group, information for identifying the reference point, and the identification number of the fire hydrant included in the group. In addition, the calculation processing unit 14 may also include information for identifying valves and plugs included in the group, in addition to fire hydrants, in the list.

[0026] The display processing unit 15 displays the number of hydrants that can be opened on the pipeline diagram in a way that allows for identification, corresponding to the position of the reference point. The display processing unit 15 makes it easy to visually understand which fire hydrants can be opened and how many there are.

[0027] Figure 3 shows an example of the display processing unit 15's display of the number of hydrants that can be opened. In Figure 3, the position of each of the multiple reference points is shown by a circle. In addition, the number of hydrants that can be opened, grouped at each of the multiple reference points, is shown by a circular pattern. In this case, the user can easily understand the number of hydrants that can be opened by the position and pattern of the circles. Note that the display of the number of hydrants that can be opened by the display processing unit 15 is not limited to the above example, and the number of hydrants that can be opened may be shown by the color of the circle, etc. Also, the reference points may be shown by symbols other than circles.

[0028] The determination unit 16 determines whether it is necessary to change the number of fire hydrants within a group, which indicates the number of fire hydrants included in the group, based on the number of hydrants that can be opened. The determination unit 16 determines whether the number of fire hydrants within a group is appropriate by comparing it with the number of fire hydrants within a group determined by the user, including the business entity that provides the fire hydrants, or by referring to the hydraulic suitability. If the number of fire hydrants within a group is not appropriate, the determination unit 16 determines that it is necessary to change the number of fire hydrants within a group.

[0029] For example, if the number of other fire hydrants within a predetermined distance of any of the fire hydrants in a group is less than a predetermined value, it is considered that there is a shortage of fire hydrants. In this case, the judgment unit 16 determines that it is necessary to increase the number of fire hydrants in the group. This allows for an accurate assessment of the shortage of fire hydrants and provides an opportunity to deploy an appropriate number of fire hydrants. The predetermined distance is determined by the rules of the user, including the business entity that installs the fire hydrants, or by the Fire Service Act, etc., and is, for example, 180m, but is not limited to this. The predetermined distance may also be determined by the number of steps it would take to actually walk between fire hydrants.

[0030] Furthermore, for example, suppose the group includes at least a first fire hydrant, a second fire hydrant, and a third fire hydrant. In this example, if the distance from the first fire hydrant to the third fire hydrant is approximately the same as the distance from the second fire hydrant to the third fire hydrant, then the third fire hydrant can be reached from either the first or second fire hydrant with roughly the same travel distance. Therefore, either the first or second fire hydrant is considered unnecessary. In this case, the determination unit 16 determines that it is necessary to reduce the number of fire hydrants in the group by excluding either the first or second fire hydrant from the group. This allows for an accurate assessment of the surplus of fire hydrants in the group and provides an opportunity to allocate an appropriate number of fire hydrants.

[0031] In this context, "the distance from the first to the third fire hydrant is approximately the same as the distance from the second to the third fire hydrant" means that the third fire hydrant lies within the overlapping range of circles centered on the first and second fire hydrants, each with a radius equal to the distance considered for the reach of a fire hose (for example, 180m as mentioned above). Therefore, if the above circles do not overlap, neither the first nor the second fire hydrant is excluded from the group due to their positional relationship with the third fire hydrant.

[0032] The optimization processing unit 17 optimizes the pipeline design based on the number of hydrants that can be opened. For example, at reference points with a small number of hydrants that can be opened, the optimization processing unit 17 improves the firefighting capacity of each fire hydrant by performing optimizations such as increasing the diameter of the pipeline. Also, at reference points with a large number of hydrants that can be opened, the optimization processing unit 17 calculates the pipeline diameter necessary to ensure the required water pressure for the water discharged from each fire hydrant. Furthermore, for example, if two pipelines arranged in parallel have fire hydrants of the same group in each, one of the fire hydrants is considered unnecessary. In this case, the optimization processing unit 17 reconsiders the arrangement of the fire hydrants so that one of the fire hydrants is removed. According to the evaluation device 1, the optimization processing unit 17 optimizes the pipeline, ensuring optimal firefighting operations.

[0033] The optimization processing unit 17 may not change the location of fire hydrants when optimizing the pipeline design. However, the optimization processing unit 17 may relocate fire hydrants as needed. For example, when rerouting a pipeline, the optimization processing unit 17 may place fire hydrants in an effective location depending on the surrounding environment.

[0034] The display unit 20 is controlled by the display processing unit 15 and displays a pipeline diagram that can identify the number of valves that can be opened corresponding to the position of a reference point. Any known display device can be used as the display unit 20 without any particular restrictions. The display unit 20 may also appropriately display images that show information related to calculations in the calculation unit 10, such as the hydraulic analysis results from the hydraulic analysis unit 13 and / or the calculation results of the number of valves that can be opened from the calculation processing unit 14.

[0035] The input unit 30 receives user input to the evaluation device 1. Any known input device can be used as the input unit 30 without any particular restrictions. Examples of user input include input for specifying a reference point and input for setting a predetermined range for grouping fire hydrants.

[0036] The storage unit 40 stores information necessary for processing in the calculation unit 10. Any known storage device can be used as the storage unit 40 without any particular restrictions. The information stored in the storage unit 40 may include, but is not limited to, a pipeline diagram, the diameter of each pipeline included in the pipeline diagram, the hydraulic analysis results from the hydraulic analysis unit 13, and the number of valves that can be opened calculated by the calculation processing unit 14. The evaluation device 1 does not necessarily have to include the storage unit 40, and may be configured to communicate with an external storage device that stores the information necessary for processing in the calculation unit 10.

[0037] (Evaluation method) Figure 4 is a flowchart showing an example of an evaluation method according to an embodiment of the present invention. In the evaluation method illustrated in Figure 4, the designation processing unit 11 designates a reference point in the pipeline diagram based on user input (S1, designation processing step). The reference point may be single or multiple, but in the following description, it will be assumed that there are multiple reference points.

[0038] The grouping processing unit 12 specifies a predetermined range for grouping fire hydrants based on user input, for any reference point where fire hydrants have not yet been grouped (S2). Furthermore, the grouping processing unit 12 performs grouping, which groups together multiple fire hydrants located within the predetermined range from the reference point (S3, grouping processing step).

[0039] The grouping processing unit 12 determines whether or not there are reference points where fire hydrants have not been grouped (S4). If there are reference points where fire hydrants have not been grouped (YES in S4), the grouping processing unit 12 repeats the process from step S2. If there are no reference points where fire hydrants have not been grouped (NO in S4), the grouping processing unit 12 creates a list of fire hydrants grouped by reference point (S5).

[0040] The hydraulic analysis unit 13 specifies the amount of fire extinguishing water per valve based on user input for any group for which the number of valves that can be opened has not been calculated (S6). The calculation processing unit 14 also specifies the water pressure determination criteria based on user input (S7). Note that step S7 only needs to be executed by step S9, which will be described later, and may be executed after step S8, for example.

[0041] The hydraulic analysis unit 13 performs a hydraulic analysis on each of the grouped fire hydrants (S8, hydraulic analysis step). The calculation processing unit 14 calculates the number of fire hydrants that can be opened based on the hydraulic analysis results from the hydraulic analysis step (S9, calculation step).

[0042] The calculation processing unit 14 determines whether or not there are any groups for which the number of hydrants that can be opened has not been calculated (S10). If there are any groups for which the number of hydrants that can be opened has not been calculated (YES in S10), the hydraulic analysis unit 13 and the calculation processing unit 14 repeat the process from step S6. If there are no groups for which the number of hydrants that can be opened has not been calculated (NO in S10), the calculation processing unit 14 creates a list of reference points that include fire hydrants in the group whose minimum water pressure did not meet the water pressure judgment criteria (S11).

[0043] The display processing unit 15 displays the number of hydrants that can be opened on the pipeline diagram on the display unit 20 in an identifiable manner (S12). The judgment unit 16 determines whether or not changes are necessary for the number of fire hydrants in each group (S13). The optimization processing unit 17 optimizes the pipeline design based on the number of hydrants that can be opened (S14). Steps S12 to S14 may be executed in any order. Also, two or more of steps S12 to S14 may be executed in parallel.

[0044] This concludes the evaluation method illustrated in Figure 4. When optimizing pipeline design, repeating the evaluation method illustrated in Figure 4 multiple times will enable the design of a pipeline that takes into account the optimal number and placement of fire hydrants.

[0045] Step S2 is not mandatory in the evaluation method performed by the evaluation device 1. If the evaluation method does not include step S2, the predetermined range is specified in advance, for example, by the designer of the evaluation device 1.

[0046] Furthermore, steps S13 and S14 are not mandatory in the evaluation method performed by the evaluation device 1. If the evaluation method does not include step S13, another device or user may determine whether the number of fire hydrants in the group needs to be changed. Also, if the evaluation method does not include step S14, another device or user may optimize the pipeline design.

[0047] [Examples of implementation using software] The function of the evaluation device 1 (hereinafter referred to as "the device") is an evaluation program for causing the device to function as a computer, and can be realized by an evaluation program for causing the computer to function as each control block of the device (particularly each part included in the arithmetic unit 10).

[0048] In this case, the apparatus includes a computer having at least one control device (e.g., a processor) and at least one storage device (e.g., memory) as hardware for executing the evaluation program. By executing the evaluation program using this control device and storage device, each of the functions described in each of the embodiments is realized. In other words, the evaluation program causes the computer to execute the above-mentioned designation processing step, grouping processing step, hydraulic analysis step, and calculation step.

[0049] The evaluation program described above may be recorded on one or more computer-readable recording media, not temporary ones. These recording media may or may not be provided by the device. In the latter case, the evaluation program may be supplied to the device via any wired or wireless transmission medium.

[0050] Furthermore, some or all of the functions of each of the above control blocks can also be realized by logic circuits. For example, an integrated circuit in which logic circuits functioning as each of the above control blocks are formed is also included in the scope of the present invention. In addition, it is also possible to realize the functions of each of the above control blocks by, for example, a quantum computer.

[0051] Furthermore, each process described in the above embodiments may be performed by AI (Artificial Intelligence). In this case, the AI ​​may operate on the control device described above, or it may operate on other devices (for example, an edge computer or a cloud server).
