[0013] The following describes in detail an equipment management support device, an equipment management support system, an equipment management support method, and an equipment management support program according to embodiments of the present invention with reference to the accompanying drawings. Note that the present invention is not limited to these embodiments. Furthermore, the same reference numerals are used to designate the same components and members in the respective embodiments, and their description will be omitted.

[0014] Embodiment 1 <Configuration of facility management support system 100> FIG. 1 is a diagram illustrating an example of the configuration of a facility management support system 100 according to a first embodiment. The facility management support system 100 allows a user who manages multiple facilities to create a maintenance plan, such as an inspection or maintenance work, for the multiple facilities. In this disclosure, as an example, the facility management support system 100 will be described as being applied to river facilities. Examples of river facilities include, but are not limited to, dams, weirs, levees, groundsills, sluice gates, sluice gates, pumping stations, drainage pumping stations, and control gates. Hereinafter, river facilities may be simply referred to as "facilities."

[0015] 1, a facility management support system 100 according to the first embodiment includes a management device 1 and a facility management support device 2. The management device 1 and the facility management support device 2 are communicably connected to each other via a network 3. The network 3 is, for example, a wide area network (WAN) such as the Internet or a local area network (LAN).

[0016] The management device 1 is, for example, a computer installed in the office of a manager who manages the facilities, and manages information about the facilities owned by the manager. The manager is, for example, a management officer at the Ministry of Land, Infrastructure, Transport and Tourism or a local government. The manager's office is a management office that manages the facilities, such as a government agency of the country or a local government, a dam management office, or a river management office. The management device 1 is not limited to being installed in an office, and may be installed on a server outside the office or on the cloud.

[0017] The facility management support device 2 is, for example, a computer installed in the manager's office, and supports the user of the facility management support system 100 in formulating a maintenance plan. The maintenance plan is a plan for maintaining and managing multiple facilities, and may include, for example, maintenance work related to preventive maintenance or corrective maintenance. The facility management support device 2 is not limited to being installed in an office, and may also be installed on a server outside the office or on the cloud.

[0018] A user of the facility management support system 100 is, for example, but not limited to, a manager of the Ministry of Land, Infrastructure, Transport and Tourism or a local government that manages the multiple facilities described above. Hereinafter, a user of the facility management support system 100 may be simply referred to as a "user."

[0019] The management device 1 includes a communication unit 10, a processing unit 11, an input unit 12, and an output unit 13. A display device 14 and an input device 15 are externally connected to the management device 1. The facility management support device 2 includes a communication unit 20, a processing unit 21, and a storage unit 22.

[0020] The communication units 10 and 20 are connected to the network 3 and are interfaces, such as LAN terminals, for transmitting and receiving information to and from each other via the network 3. The communication units 10 and 20 are not limited to LAN terminals, which are wired network terminals, and may perform wireless communication using, for example, a wireless LAN system.

[0021] The input unit 12 in the management device 1 is an input interface for inputting user instructions and data from outside the management device 1, and is, for example, a USB terminal. The input unit 12 is connected to the input device 15 by a USB cable, and the processing unit 11 accepts user instructions from the input device 15 via the input unit 12. Here, the input device 15 may be any device that accepts some kind of input operation from the user, and may be, for example, a keyboard, a mouse, or a touch panel. The input device 15 and the input unit 12 may be connected wirelessly or via a wired connection.

[0022] The processing unit 11 in the management device 1 is a processor such as a CPU, and is connected to the communication unit 10, the input unit 12, and the output unit 13. When a user operates the input unit 12, the processing unit 11 processes the input information and sends it to the communication unit 10. The communication unit 10 transmits the information received from the processing unit 11 to the equipment management support device 2.

[0023] The output unit 13 is an output interface for outputting data acquired by the processing unit 11 from the equipment management support device 2, calculation results, etc., to outside the management device 1, and examples of such an output interface include an HDMI terminal (HDMI is a registered trademark), a DVI terminal, and a D-Sub terminal. The output unit 13 is connected to the display device 14 via various cables, and transmits various pieces of information acquired from the processing unit 11 to the display device 14.

[0024] The display device 14 is a device for displaying information obtained from the facility management support device 2, and examples thereof include a liquid crystal display, a plasma display, an organic light-emitting diode (OLED) display, a smartphone, and a portable tablet device. Since multiple users manage multiple facilities in a management office, the display device 14 may be a large multi-screen system combining multiple displays to improve visibility. While the display device 14 is shown in FIG. 1 as being provided in the management device 1, it may also be provided in the facility management support device 2. When the display device 14 is provided in the facility management support device 2, it may be configured to function as an HMI (Human Machine Interface), allowing a user to operate the facility management support device 2 by directly touching the display device 14.

[0025] The processing unit 21 of the facility management support device 2 is a processor such as a CPU, and is connected to the communication unit 20 and the storage unit 22. The processing unit 21 executes the facility management support program installed in the storage unit 22, controls the operations of the communication unit 20 and the storage unit 22, and performs calculation processing and the like.

[0026] The processing unit 21 of this embodiment, as an equipment management support program, executes the following steps: acquiring equipment information indicating the status of the equipment, storing the acquired equipment information, acquiring equipment surroundings information indicating the surroundings of the equipment, storing the acquired equipment surroundings information, calculating the importance of the equipment based on the equipment surroundings information, and creating a maintenance plan for the equipment based on the calculated importance. Details of the equipment information, equipment surroundings information, map information, and importance will be described later.

[0027] The storage unit 22 is a storage medium that stores the facility management support program executed by the processing unit 21 and various data, and examples thereof include a hard disk drive (HDD), a solid state drive (SDD), a USB flash memory, an SD card, etc. In this embodiment, the storage unit 22 is provided inside the facility management support device 2, but may also be provided externally.

[0028] The storage unit 22 stores map data 221 that represents geographical information. The map data 221 is, for example, a hazard map that can predict damage caused by natural disasters. The map data 221 is not limited to a hazard map, and may be a topographical map, a satellite image, an aerial photograph, a 3D map, or the like. The map data 221 may also include elevation data, etc.

[0029] The storage unit 22 stores facility surroundings information, which is information about the surroundings of facilities owned by the administrator, in a facility surroundings database 222. The facility surroundings information includes, for example, population data 2221, flood depth data 2222, flooded area data 2223, land use data 2224, and public facility data 2225. The population data 2221 is data indicating the population status and fluctuations in a specific area. The flood depth data 2222 is data indicating the depth to which a specific area will be flooded if a flood occurs in that area. The flooded area data 2223 is data indicating the extent to which a specific area will be flooded if a flood occurs in that area. The land use data 2224 is data indicating the purpose for which land is used in that specific area. The public facility data 2225 is information indicating the locations, names, addresses, etc. of important public facilities such as evacuation shelters, hospitals, and social welfare facilities. The facility surroundings information described above is not limited to these, and may be any information that can provide an understanding of some situation in a specific area, such as transportation network information or power supply information.

[0030] The storage unit 22 stores facility information, which is information about facilities stored by the manager, in the plan database 223. The facility information includes inspection status data 2231, useful life data 2232, cost data 2233, and estimated failure rate data 2234. FIG. 2 shows an example of the inspection status data 2231 stored in the plan database 223. As shown in FIG. 2, the inspection status data 2231 records a condition evaluation, which is the inspection result of each facility, on a scale of 1 to 5, and associates the date on which the condition evaluation was performed with each facility ID and facility name. The facility management support device 2 acquires the inspection status data 2231 from the management device 1 and stores it in the plan database 223.

[0031] 3 shows an example of useful life data 2232 stored in the plan database 223. As shown in Fig. 3, the useful life data 2232 records the useful life, which is the period during which each piece of equipment is considered to operate normally, in association with each equipment ID and equipment name. The equipment management support device 2 acquires the useful life data 2232 from the management device 1 and stores it in the plan database 223.

[0032] Fig. 4 shows an example of cost data 2233 stored in the plan database 223. As shown in Fig. 3, the cost data 2233 records the land or building acquisition costs required to acquire equipment, the annual maintenance costs and renewal costs required to maintain and manage the equipment, and the disposal costs required when disposing of the equipment, in association with each equipment ID and equipment name. The equipment management support device 2 obtains the cost data 2233 from the management device 1 and stores it in the plan database 223.

[0033] 5 shows an example of estimated failure rate data 2234 stored in the plan database 223. As shown in Fig. 5, the estimated failure rate data 2234 records estimated failure rates, which are the probability of deterioration information that indicates that each piece of installed equipment will fail due to deterioration, in association with equipment IDs and equipment names for each period. The equipment management support device 2 obtains the estimated failure rate data 2234 from the management device 1 and stores it in the plan database 223.

[0034] 2 to 5 stored in the storage unit 22 are not limited to data acquired from the management device 1, but may be data acquired from a terminal device (not shown) that can transmit facility information from outside. The administrator of the terminal device may be the same as the administrator of the management device 1 or a person authorized by the administrator of the management device 1. The importance index data 2235 stored in the plan database 223 will be described later.

[0035] <Hardware configuration example of facility management support device 2> FIG. 6 shows an example of the hardware configuration of the equipment management support device 2. As shown in FIG. 6, the equipment management support device 2 includes a processor 100a, a memory 101a, and an interface circuit 102a. The processor 100a, the memory 101a, and the interface circuit 102a are communicatively connected to each other via a system bus 103a, and can transmit and receive information to and from each other. The communication unit 20 in FIG. 1 is configured to be connectable to the interface circuit 102a and can receive information from the management device 1. In the example configuration of FIG. 6, the processing unit 21 is realized by the processor 100a, and the storage unit 22 is realized by the memory 101a. The processor 100a of the equipment management support device 2 executes the function of the processing unit 21 by reading and executing the equipment management support program stored in the memory 101a. The contents of the storage unit 22 may be stored in the same memory 101a or in a separate memory.

[0036] The processor 100a is an example of a processing circuit and includes one or more of a CPU (Central Processing Unit), a DSP (Digital Signal Processor), and a system LSI (Large Scale Integration). The memory 101a includes one or more of a non-volatile or volatile semiconductor memory such as a RAM (Random Access Memory), a ROM (Read Only Memory), a flash memory, an EPROM (Enable Program Read Only Memory), a magnetic disk, a flexible memory, an optical disk, a compact disk, and a DVD (Digital Versatile Disc). The facility management support device 2 may include an integrated circuit such as an ASIC (Application Specific Integrated Circuit) and an FPGA (Field Programmable Gate Array).

[0037] In the facility management support system 100, the facility management support device 2 may be configured to have the functions of the management device 1. Furthermore, although the hardware configuration has been described in the first embodiment, the other embodiments of the present disclosure may also employ a similar hardware configuration.

[0038] <Maintenance plan creation process of facility management support device 2> The maintenance plan creation process in the facility management support device 2 will be described with reference to FIG.

[0039] 7 shows a flowchart of the maintenance plan creation process performed by the equipment management support device 2 of the equipment management support system 100. In step S101, the equipment management support device 2 acquires equipment surroundings information from the management device 1 and stores the equipment surroundings information in the equipment surroundings database 222 of the storage unit 22. Next, in step S102, the equipment management support device 2 calculates a risk score based on the equipment surroundings information acquired from the management device 1. The risk score is an evaluation of the degree of risk in the event of a disaster in a specific area. In this case, disasters include, for example, earthquakes, tsunamis, and floods, but are not limited to these, and unexpected equipment failures are also considered to be disasters.

[0040] The risk score calculated by the facility management support device 2 will now be described with reference to FIG. 8. FIG. 8 is an example showing the risk score calculated by the evaluation unit 211 of the facility management support device 2 in step S102 of FIG. 7. As shown in FIG. 8, the facility management support device 2 creates a risk score (population) when the facility surrounding information acquired in step S101 is population data 2221. The risk score (population) is set so that if the population around the facility is 0 to 50 people, the risk score is 1; if it is 50 to 300 people, the risk score is 2; if it is 300 to 1000 people, the risk score is 3; if it is 1000 to 3000 people, the risk score is 4; and if it is 3000 or more people, the risk score is 5. The risk score (population) shown in FIG. 8 is an example, and the numerical value of the risk score for the population will vary depending on the region from which the population data 2221 is acquired. Furthermore, if the facility surrounding information acquired in step S101 is flood depth data 2222, the facility management support device 2 creates a risk score (flood depth). The risk score (flood depth) is set as follows: if the flood depth of the area around the facility is 0.0 to 0.5 m, the risk score is 1; if it is 0.5 to 1.0, the risk score is 2; if it is 1.0 to 2.0, the risk score is 3; if it is 2.0 to 5.0, the risk score is 4; and if it is 5.0 or more, the risk score is 5. The risk score (flood depth) is merely an example, and the risk score value for the flood depth will vary depending on the region from which the flood depth data 2222 is acquired. While FIG. 8 illustrates risk scores for population data 2221 and flood depth 2222, similar calculations are performed for other facility surrounding information, such as flood area data 2223, land use data 2224, and public facility data 2225.

[0041] 7, the processing performed by the facility management support device 2 after the facility management support device 2 calculates the risk scores in step S102 will be described. In step S103, the facility management support device 2 divides the map data 221 stored in the storage unit 23 into a grid, and creates an area map 4 in which a risk score is assigned to each area divided into the grid based on the risk scores calculated in step S102.

[0042] The area map 4 created by the equipment management support device 2 will now be described with reference to FIG. 9. FIG. 9 is an example of the area map 4 created by the evaluation unit 211 of the equipment management support device 2 in step S103 of FIG. 7. As shown in FIG. 9, in step S103, the equipment management support device 2 creates the area map 4 by dividing the map data 221 into a grid and assigning A to E to the top edge and 1 to 4 to the left edge. The area map 4 created by the equipment management support device 2 is divided into zones by the letters and numbers assigned to the top and left edges. Of the facilities displayed on the area map 4 shown in FIG. 9, it can be seen that "□□ Water Gate" belongs to zone 2B, "○○ Weir" belongs to zone 2C, "△△ Weir" belongs to zone 3B, and "◇◇ Water Gate" belongs to zone 4A. The letters and numbers assigned to the area map 4 are not limited to these. In the area map 4 according to the present disclosure, the 1E zone is the upstream side, and the 4A zone is the downstream side.

[0043] FIG. 10 is an example of a zone-specific risk score, which represents the risk score for each zone in the area map 4 shown in FIG. 9 and is created by the facility management support device 2. As shown in FIG. 10, the zone-specific risk score is recorded by associating the risk scores of the facility surrounding information calculated in step S102 with each zone in the area map 4. The zone-specific risk score shown in FIG. 10 is a five-point scale from 1 to 5, similar to the example of the risk score shown in FIG. 8, with numbers closer to 1 indicating a lower risk in the event of a disaster and numbers closer to 5 indicating a higher risk in the event of a disaster. The zone-specific risk score shown in FIG. 10 is recorded for zones 1A to 1E in the area map 4 shown in FIG. 9, but the other zones 2A to 4E are omitted. For example, as shown in FIG. 10, the "Population" column of the zone-specific risk score indicates that zones 1A and 1B have a large population and therefore a high risk score, because they face the "urban area" shown in the area map 4.

[0044] Returning to FIG. 7, the processing performed by the equipment management support device 2 after calculating the area-specific risk scores in step S103 will be described. In step S104, the evaluation unit 211 of the equipment management support device 2 estimates an impact area, which is an area that will affect the surrounding area if each piece of equipment displayed on the area map 4 fails, based on the equipment information and the equipment surrounding information. FIG. 11 shows an example of an impact area estimated by the equipment management support device 2 in step S104 of FIG. 7. FIG. 11 indicates whether or not an impact will be felt by assigning a "1" if the failure of each piece of equipment on the area map 4 of FIG. 9 will have an impact on the surrounding area, and a "0" if there is no impact. For example, as shown by the impact area in FIG. 11, if the "XX Weir" on the area map 4 of FIG. 9 fails, it can be seen that areas 1C to 1E will be affected. Furthermore, the impact area shown in FIG. 11 describes areas 1A to 1E of the area map 4 of FIG. 9, but omits the description of areas 2A to 4E.

[0045] 7, a description will be given of the processing performed after the facility management support device 2 estimates the affected area in step S104. In step S105, the facility management support device 2 tallyes the above-mentioned zone-specific risk scores and information on the affected area.

[0046] Next, in step S106, the facility management support device 2 calculates importance index data 2235 indicating the importance of each facility, taking into account the extent of damage that would occur if each facility were to fail, based on the zone-specific risk scores and information on the affected areas compiled in step S105. FIG. 12 is a diagram showing an example of the importance index data 2235 calculated by the evaluation unit 211 of the facility management support device 2 in step S106 of FIG. 7. FIG. 12 shows the importance of each facility listed on the area map 4 shown in FIG. 9. As shown in FIG. 12, of the facilities on the area map 4, "XX Weir" is calculated to have the highest importance, and "◇◇ Water Gate" the lowest. The importance index data 2235 calculated by the evaluation unit 211 of the facility management support device 2 is stored in the plan database 223 of the storage unit 22.

[0047] Here, the importance of the importance index data 2235 shown in FIG. 12 will be specifically explained. Area map 4 shown in FIG. 9 shows "weirs" and "floodgates" installed as facilities. "Weirs" are facilities installed mainly in the main stream of a river. They limit and maintain the water volume during normal times and allow the water to flow smoothly during floods. "Floodgates" are facilities installed mainly in tributaries of a river. They are open during normal times, but close during floods to prevent large amounts of water from flowing into the tributaries and causing flooding, thereby acting as levees. As shown in FIG. 12, "XX Weir" and "△△ Weir," which are installed in the main stream of the river shown in area map 4 of FIG. 9 and are surrounded by residential or industrial areas, have high risk in the surrounding information of each facility, and are therefore calculated to have a high importance. Furthermore, among the "floodgates" installed in the tributaries of the river, "□□ Floodgate" is located near an urban area and a hospital, and therefore has a high importance due to the high risk of the surrounding information of each facility. In contrast, the "◇◇ floodgate" is at high risk in the flooded area, but due to the small population and the lack of nearby facilities, the information surrounding each facility is at low risk, and it can be seen that its importance is calculated to be low compared to other facilities.

[0048] Returning to FIG. 7 , the processing performed after the equipment management support device 2 calculates the importance index data 2235 in step S106 will be described. In step S107, the equipment management support device 2 creates an equipment maintenance plan for each piece of equipment based on the importance index data 2235 calculated by the evaluation unit 211. FIG. 13 is an example of an equipment maintenance plan created by the equipment management support device 2, and shows a maintenance plan for each piece of equipment shown in the area map 4 in FIG. 9. The equipment maintenance plan shown in FIG. 13 is created based on the importance index data 2235 as well as the equipment information stored in the plan database 223. As shown in FIG. 13, it is recommended that a maintenance plan be carried out for the "XX weir" from 2025 to 2026.

[0049] Next, in step S108, the equipment management support device 2 outputs the equipment maintenance plan created in step S107 to the management device 1, whereby the equipment maintenance plan is displayed on the display device 14. The output destination of the equipment maintenance plan created by the equipment management support device 2 is not limited to the display device 14, and the plan may be output to, for example, another system or another device that is communicably connected to the equipment management support device 2.

[0050] <Display screen on the display device 14> The display screen 5 displayed on the display device 14 connected to the management device 1 will be described with reference to FIG.

[0051] Fig. 14 shows an example of a display screen 5 displayed by the display device 14 connected to the management device 1. The display screen 5 includes an equipment list area 51 that displays a list of equipment managed by the equipment management support system 100, an area map area 52 that displays the area map 4 described in Fig. 9, an equipment information area 53 that displays equipment information about the equipment, and an equipment maintenance plan area 54 that displays the equipment maintenance plan described in Fig. 13.

[0052] The following describes the functions of the display screen 5 shown in FIG. 14. The equipment list 51 displays a list of equipment managed by the user. When the user selects equipment, the equipment can be displayed on the area map displayed in the area map area 52. Furthermore, when equipment is selected from the equipment list 51, the selected equipment may be displayed in the center of the area map area 52. The area map area 52 allows the user to freely check the area map 4 by moving the displayed area map 4 up, down, left, right, and zooming in and out through operation of the input device 15 connected to the management device 1. The equipment information area 52 can display information about equipment selected in the area map area 52 through operation of the input device 15. Furthermore, by selecting equipment displayed in the area map area, the equipment information area 52 may be displayed. The equipment maintenance plan area 54 displays a recommended equipment maintenance plan for each piece of equipment selected in the equipment list area 51. Each area shown on the display screen 5 in FIG. 14 can be arranged as desired by the user, and some areas may not be displayed.

[0053] According to this embodiment, as described above, the equipment management support device 2 calculates the importance of each piece of equipment, taking into account the extent of damage caused by the failure of that piece of equipment, based on equipment information indicating the status of that piece of equipment and equipment surrounding information, which is information about the surrounding area of ​​that piece of equipment. Furthermore, the equipment management support device 2 prioritizes each piece of equipment based on the calculated importance in addition to the equipment deterioration information, thereby making it possible to create an equipment maintenance plan that minimizes damage in the event of a disaster, taking into account the impact of equipment failure on the surrounding area. This allows the user to formulate a safer and more efficient equipment maintenance plan that takes into account damage caused by equipment failure in the event of a disaster, based on the equipment maintenance plan created by the equipment management support device 2.

[0054] Embodiment 2 <Maintenance plan creation process of facility management support device 2> The maintenance plan creation process of the equipment management support device 2 in the second embodiment will be described with reference to FIG. 15. In FIG. 15, steps SN (N is a natural number) equivalent to those in the first embodiment are numbered the same, and some of them are omitted for convenience of explanation. Below, the characteristic parts of the second embodiment will be described. In step S201, the equipment management support device 2 newly registers equipment based on equipment information input by the user of the management device 1. The equipment management support device 2 stores the equipment information of the equipment newly registered by the user in the plan database 223 of the storage unit 22. Next, in step S202, the equipment management support device 2 acquires equipment peripheral information, which is peripheral information of the equipment newly registered in step S201, from the management device 1, and stores the acquired equipment peripheral information in the equipment peripheral database 222 of the storage unit 22.

[0055] <Display screen on the display device 14> The display screen 5 displayed on the display device 14 connected to the management device 1 will be described with reference to Fig. 16. In Fig. 16, components with the same reference numerals as those in Fig. 14 indicate components that are the same as or equivalent to those in the first embodiment.

[0056] 16 shows an example of the display screen 5 displayed by the display device 14 connected to the management device 1. In Fig. 16, the display screen 5 has a new registration button 55 for registering new equipment on the area map region 52. The new equipment registration executed by the equipment management support device 2 in step S201 can be started by the user operating the input device 15 to press the new registration button 55.

[0057] An example of a user's operation of the input device 15 will be described. For example, the user uses the input device 15 to select an arbitrary position on the area map in the area map region 52 and presses the new registration button 55. When the new registration button 55 is pressed, an equipment registration region 56 shown in FIG. 16 is displayed. The user enters information about the equipment to be newly registered, such as the equipment name, location, installation date, and various data, into the equipment registration region 56 and executes the registration. The newly registered equipment is added to the equipment list 51 and the area map region 52.

[0058] When a user registers a new asset, the equipment management support device 2 executes the maintenance plan creation process shown in Fig. 15 based on information about the newly registered equipment, the equipment information, and the equipment peripheral information stored in the storage unit 22. The maintenance plan created by the equipment management support device 2 is updated to an equipment maintenance plan 54 shown in Fig. 16.

[0059] According to this embodiment, by creating a maintenance plan based on information about equipment newly registered in the equipment management support device 2, and the equipment information and equipment peripheral information stored in the storage unit 22, it becomes possible to create a maintenance plan that includes equipment that is not stored in the plan database 223. By checking the maintenance plan displayed on the display device 14 connected to the management device 1, the user can formulate a maintenance plan that takes into account equipment that is not stored in the plan database 223.

[0060] Embodiment 3 <Configuration of facility management support system 100> The configuration of the facility management support system 100 according to the third embodiment will be described with reference to Fig. 17. Fig. 17 shows a configuration diagram of the facility management support system 100. In Fig. 17, components with the same reference numerals as those in Fig. 1 indicate components that are the same as or equivalent to those in the first embodiment. Here, while communication on the network 3 in the first embodiment was between the management device 1 and the facility management support device 2, in the third embodiment, the management device 1 and the facility management support device 2 are connected so as to be able to communicate with an external server 6 as well.

[0061] The external server 6 is, for example, a website from which observation data and forecast data published by the Japan Meteorological Agency can be obtained. The information published by the Japan Meteorological Agency is, for example, disaster information 61, which is information for protecting oneself from disasters, or weather information 62, which is statistical data related to weather. The disaster information 61 and weather information 62 are, for example, disaster prevention weather information and weather statistical information published by the Japan Meteorological Agency, but are not limited to these.

[0062] The equipment management support device 2 of the third embodiment periodically acquires disaster information 61 and weather information 62 from the external server 6 via the network 3. The equipment management support device 2 stores external data 2226, which is at least one of the disaster information 61 and weather information 62 acquired from the external server, in the equipment surroundings database 222. Therefore, the processing unit 21 of the equipment management support device 2 calculates the importance of the equipment taking the external data 2226 into consideration in the evaluation unit 211, and creates a maintenance plan based on the importance in the plan 212.

[0063] <Maintenance plan creation process of facility management support device 2> The maintenance plan creation process in the facility management support device 2 will be described with reference to FIG.

[0064] 18 shows a flowchart of the maintenance plan creation process performed by the equipment management support device 2. In Fig. 18, steps SN (N is a natural number) equivalent to those in embodiment 1 are numbered the same, and a description will be given of the characteristic parts in embodiment 3, with a description of equivalent steps being omitted. In step S301, the equipment management support device 2 acquires external data 2226 from the external server 6 and stores it in the equipment surroundings database 222.

[0065] Next, in step S302, the facility management support device 2 calculates a risk score based on the external data 2226 acquired from the external server 6 in step S301 and the facility surroundings information stored in the facility surroundings database 222. The risk score created in step S302 is created taking into account the external data 6, and the importance in the subsequent maintenance plan creation process in step S106 is also a calculation result that takes into account the external data 6.

[0066] According to this embodiment, the equipment management support device 2 calculates the importance of each piece of equipment based on external data 6 acquired from the external server 6, and prioritizes each piece of equipment based on the importance, thereby making it possible to create an equipment maintenance plan that minimizes damage in the event of a disaster, taking into consideration not only the impact of equipment failure on the surrounding area but also externally obtained information such as environmental changes. This enables the user to formulate a safer and more efficient equipment maintenance plan based on the maintenance plan created by the equipment management support device 2, taking into consideration environmental changes and the like.

[0067] Furthermore, in the third embodiment, as an example, the external data 6 is acquired in step S301 before the risk score is calculated in step S302, but this is not limiting, and for example, the external data 6 may be acquired after the importance of each piece of equipment is calculated in step S106. At this time, the external data 6 is not used in the calculation of the importance executed by the evaluation unit 211. Therefore, the external data 6 is stored in the plan database 223, and is used when the planner 212 creates a maintenance plan for the equipment in step S107.

[0068] Embodiment 4 <Configuration of facility management support system 100> The configuration of the facility management support system 100 according to the fourth embodiment will be described with reference to Fig. 19. Fig. 19 shows a configuration diagram of the facility management support system 100. In Fig. 19, components with the same reference numerals as those in Fig. 17 indicate components that are the same as or equivalent to those in the third embodiment. Here, the facility management support device 2 according to the fourth embodiment has a prediction unit 213 as a function of the processing unit 21, and a trained model 224 in the memory unit 22.

[0069] <Maintenance plan creation process of facility management support device 2> The prediction unit 213 of the equipment management support device 2 will now be described in detail with reference to FIG. 20. FIG. 20 is a diagram illustrating functional blocks of the equipment management support device 2. The prediction unit 213 includes a learning unit 2131 and an inference unit 2132. The learning unit 2131 learns the importance of equipment through so-called supervised learning, for example, according to a neural network model. Here, supervised learning is a technique in which data pairs of inputs and resulting labels are provided to the learning unit 2131, and the learning unit 2131 learns the characteristics of the training data and infers the results from the inputs. The learning unit 2131 acquires training data created based on a combination of at least one piece of equipment information stored in the equipment surroundings database 222 of the storage unit 22 and at least one piece of equipment surroundings information stored in the plan database 223. The learning unit 2131 then generates a trained model 224 that has learned the importance of equipment through supervised learning according to the acquired training data. At this time, the trained model 224 generated by the learning unit 2131 is stored in the storage unit 22.

[0070] The inference unit 2132 uses at least one of the facility information and the facility surrounding information newly acquired from the management device 1 as inference data. The inference unit 2132 infers the importance obtained by using the trained model 224. That is, by inputting at least one of the newly acquired facility information and the facility surrounding information into the trained model 224, it is possible to output the importance inferred from at least one of the facility information and the facility surrounding information.

[0071] The importance inferred by the inference unit 2132 is output to the planner 212. The evaluation unit 211 determines the importance of each piece of equipment based on the importance inferred by the inference unit 2132. The planner 212 can create a maintenance plan for the equipment based on the importance determined by the evaluation unit 211.

[0072] In this embodiment, the importance is inferred using the learned model 224 learned by the prediction unit 213 of the equipment management support device 2, but it is also possible to obtain a learned model from outside the equipment management support device 2 and output the importance based on the learned model.

[0073] In this embodiment, a case has been described in which supervised learning is applied to the learning algorithm used by the learning unit 2131, but the present invention is not limited to this. As for the learning algorithm, in addition to supervised learning, semi-supervised learning and the like can also be applied.

[0074] It is also possible to add or remove equipment from which the learning unit 2131 collects learning data during the process. Furthermore, the learning unit 2131 that has learned the importance of a certain piece of equipment may be applied to another equipment management support device 2, and the importance of the other equipment management support device 2 may be re-learned and updated.

[0075] The learning algorithm used in the learning unit 2131 can be deep learning, which learns to extract the feature itself, such as at least one of the equipment information and the equipment surrounding information, or machine learning can be performed according to other known methods, such as genetic programming, functional logic programming, support vector machines, etc.

[0076] The learning unit 2131 and the inference unit 2132 are used to learn the importance of multiple pieces of equipment, but may be, for example, devices connected to the equipment management support device 2 via a network and separate from the equipment management support device 2. The learning unit 2131 and the inference unit 2132 may also exist on a cloud server separate from the equipment management support device 2.

[0077] According to this embodiment, the equipment management support device 2 can infer the importance of equipment based on at least one of the accumulated equipment information and equipment surrounding information, as well as newly acquired equipment information and equipment surrounding information. Therefore, the equipment management support device 2 can create an equipment maintenance plan that more accurately predicts future risks, taking into account damage caused by disasters that have occurred from the past to the present. By referring to the maintenance plan created by the equipment management support device 2, the user can create a safer and more efficient equipment maintenance plan that more accurately predicts damage to the surrounding area due to equipment failure in the event of a disaster.

[0078] In this disclosure, we have described a maintenance plan for preventive maintenance or corrective maintenance that takes action before equipment fails, but it is also possible to update the maintenance plan based on information about the equipment that has suddenly failed.

[0079] The facility management support system 100 shown in each embodiment is an example, and each embodiment can be combined, modified, or omitted as appropriate. In addition, combining with other known technologies is also within the scope of the technical ideas shown in the embodiments.
