Description

The present disclosure relates to a maintenance support system, a maintenance support device, and a maintenance support method that detects changes in electrical equipment and notifies an administrator.

In electrical facilities consisting of power receiving and distribution equipment or distribution boards, in order to safely supply electricity, maintenance work is carried out by maintenance workers, and maintenance management is carried out by electrical equipment managers, such as managing maintenance plans and managing electrical equipment information, which is information about the electrical equipment. In addition, electrical designers may create or revise electrical equipment information at the request of the electrical equipment managers.

Conventionally, there is known technology that automatically detects changes to equipment settings using equipment information, which is information on the equipment, and maintenance information, which is information on maintenance, and then prompts the manager to change the equipment settings. The equipment diagnosis device described in Patent Document 1 determines whether equipment has been changed by comparing measurement value data at a control point contained in the equipment information read from a storage unit with measurement value data at a control point obtained from a facility management device. If the equipment diagnosis device determines that equipment has been changed, it displays a prompting screen that prompts the manager to change the equipment information settings.

JP 2014-49067 A

However, with the technology of Patent Document 1, when a component part of equipment is changed, it is not possible to notify the administrator of which equipment the component part is located in. As a result, the administrator must find out which equipment the component part is located in and then revise or request a revision of the electrical equipment information, which creates the problem of time and effort required for revision.

This disclosure has been made in consideration of the above, and aims to obtain a maintenance support system that can reduce the effort required when revising information about electrical equipment.

In order to solve the above-mentioned problems and achieve the object, the maintenance support system of the present disclosure includes a storage unit that stores part information including a correspondence between the name of the electrical equipment and each name of the first component arranged in the electrical equipment. The maintenance support system also includes an input unit that receives maintenance information that records the name of the second component for which maintenance work has been performed and the presence or absence of maintenance work or the content of the work on the second component. The maintenance support system also includes a determination unit that determines whether the first component corresponding to the second component has been changed by the maintenance work based on the maintenance information, and, if the first component has been changed, identifies the name of the changed electrical equipment based on the part information, and, if the electrical equipment has been changed, a notification creation unit that displays the identified name of the electrical equipment and the name of the first component, and creates and outputs a notification content indicating that revision is required due to the maintenance work.

The maintenance support system disclosed herein has the effect of reducing the effort required to revise information about electrical equipment.

Maintenance information 201 includes a work date, a name of the work object (hereinafter sometimes referred to as the work object name), work content, and a revision check column. The work object is a component included in the electrical equipment to be maintained, and is the component for which maintenance work was actually performed. The work date is the date and time when the maintenance work was performed, and the work object name is the name of the component that was the subject of the maintenance work. The work content is information indicating the content of the maintenance work, and the revision check column is revision information indicating whether or not the electrical equipment information needs to be revised. If a check is entered in the revision check column, it indicates that the electrical equipment information needs to be revised. An example of a work object name is a distribution board DA, and an example of work content is work to increase the number of branches from two circuits to three circuits in a circuit expansion work.

In addition, the maintenance information 201 may include information on work that is performed periodically, such as weekly inspections and monthly inspections, and information on work that is performed non-periodically, such as repair work.

The equipment information database 16 stores electrical equipment information 100, which is information about electrical equipment, load information 101, which is information about the load equipment 9, and component information 102, which is information about the parts that make up the load equipment 9. Here, the configuration of the electrical equipment information 100, the load information 101, and the component information 102 will be explained.

Figure 4 is a diagram showing an example of electrical equipment information stored in the maintenance support device of embodiment 1. The electrical equipment information 100 is created by a construction company when the electrical equipment is constructed. The electrical equipment information 100 is obtained by the administrator from the construction company and is stored in advance in the equipment information database 16.

The electrical equipment information 100 includes information on the creation date of the electrical equipment information 100, the name of the electrical equipment (hereinafter sometimes referred to as the electrical equipment name), the names of the components (hereinafter sometimes referred to as the component names), information on the specifications or product names corresponding to the component names, and a wiring diagram showing the wiring relationships of the components.

An example of an electrical equipment name registered in the electrical equipment information 100 is the P building electrical equipment. Examples of component names registered in the electrical equipment information 100 are high-voltage substation equipment H1, switchboards DA, DB, DC, high-voltage cable Ca, low-voltage cable Cb, air conditioners A1, A2, office equipment O1, O2, and a pump.

An example of the specifications of high-voltage substation equipment H1 registered in electrical equipment information 100 is receiving voltage: 6.6 kV. The component names registered in electrical equipment information 100 also include the names of load equipment 9. Of the component names registered in electrical equipment information 100, air conditioners A1 and A2, office equipment O1 and O2, and a pump are names of load equipment 9.

The wiring diagram of the electrical equipment information 100 shown in Figure 4 shows a case where high-voltage substation equipment H1 is connected to one high-voltage cable Ca and three low-voltage cables Cb. This wiring diagram also shows a case where high-voltage substation equipment H1 is connected to a switchboard DA via one low-voltage cable Cb, to a switchboard DB via one low-voltage cable Cb, and to a switchboard DC via one low-voltage cable Cb. This wiring diagram also shows a case where the switchboard DA is connected to air conditioners A1 and A2, the switchboard DB is connected to office equipment O1 and O2, and the switchboard DC is connected to a pump.

Figure 5 is a diagram showing an example of load information stored in the maintenance support device according to the first embodiment. The load information 101 is information that is created when the load equipment 9 is introduced. The load information 101 is obtained by an administrator and is pre-registered in the equipment information database 16 by the administrator.

Load information 101 includes information on the creation date of load information 101, the name of load equipment 9, the model name of load equipment 9, the drawing number of load equipment 9, the voltage of load equipment 9, the current of load equipment 9, information on cables connected to load equipment 9 such as low-voltage cable Cb, and a wiring diagram. Of the information included in load information 101, the voltage, current, etc. of load equipment 9 are the specifications of load equipment 9. The wiring diagram of load information 101 is a diagram showing the wiring relationship between components such as distribution board DA and load equipment 9 such as air conditioner A1.

An example of the name of the load equipment 9 registered in the load information 101 is an air conditioner A1. An example of the low-voltage cable Cb registered in the electrical equipment information 100 is a fire-resistant cable. The wiring diagram of the load information 101 shown in Figure 5 shows a case where the distribution board DA is connected to the air conditioner A1 via the low-voltage cable Cb.

Figure 6 is a diagram showing an example of equipment load component information stored in the maintenance support device according to embodiment 1. The component information 102 is data created by an administrator based on the electrical equipment information 100 and the load information 101, and is registered in advance in the equipment information database 16.

The component information 102 includes information indicating the correspondence between the names of the electrical equipment included in the electrical equipment information 100, the names of each component of the electrical equipment included in the electrical equipment information 100, and the names of each piece of load equipment 9 included in the load information 101.

Component information 102, which is component information, includes connection information, which is information on the connection relationships between electrical equipment and component parts. For example, Figure 6 shows that the P-building electrical equipment, which is an electrical equipment, is connected to the high-voltage substation equipment H1, the distribution boards DA, DB, and DC, the high-voltage cable Ca, and the low-voltage cable Cb, which are component parts. It also shows that air conditioners A1 and A2 are connected to the distribution board DA, that office equipment O1 and O2 are connected to the distribution board DB, and that a pump is connected to the distribution board DC.

The component information 102 is configured to allow data expansion when there are multiple pieces of electrical equipment that are subject to maintenance management by the maintenance support device 1. Specifically, when building Q electrical equipment is subject to maintenance management in addition to the building P electrical equipment shown in the electrical equipment information 100, it is possible to expand the data of the component information 102 to add information on the building Q electrical equipment, as shown in Figure 6.

The determination unit 12 determines whether or not the electrical equipment information 100 needs to be revised using the maintenance information 201 input to the input unit 11. Specifically, the determination unit 12 detects whether or not the revision check column included in the maintenance information 201 is checked, and determines that revision is necessary when it detects that a check is present. When multiple electrical equipment are registered in the component information 102, the determination unit 12 determines whether or not the electrical equipment information 100 needs to be revised for the multiple electrical equipment.

When revision is necessary, the judgment unit 12 extracts the work object name included in the maintenance information 201 and compares the extracted work object name with the component name in the component information 102. The component name registered in the electrical equipment information 100, i.e., the component name included in the component information 102, is the name of the first component. Also, the work object name included in the maintenance information 201 is the name of the second component.

The determination unit 12 identifies the electrical equipment that has been changed based on the maintenance information 201 and the component information 102. Specifically, the determination unit 12 extracts the work object name (distribution board DA in the case of FIG. 3) from the maintenance information 201, and sets the electrical equipment that includes the extracted work object name as the electrical equipment to be revised.

That is, the determination unit 12 searches for a component name that matches the work object name among the component names included in the component information 102, and sets the name of the electrical equipment to which the component name that matches the work object name belongs as the name of the electrical equipment to be revised.

The revision target is the name of the electrical equipment to be included in the notification content (notification content 121 described below) when notifying the administrator that the electrical equipment has been revised. In other words, the electrical equipment name set as the revision target is the electrical equipment name of the electrical equipment that has been changed by maintenance work. The determination unit 12 sends the set name of the electrical equipment to be revised and the maintenance information 201 to the notification creation unit 13.

The notification creation unit 13 receives the name of the electrical equipment to be revised and the maintenance information 201 from the determination unit 12. The notification creation unit 13 creates notification content 121 based on the electrical equipment name and the maintenance information 201. The notification content 121 is information for notifying that the electrical equipment information 100 needs to be revised. The notification creation unit 13 sends the created notification content 121 to the display control unit 14.

The display control unit 14 receives the notification content 121 from the notification creation unit 13 and displays the notification screen 120 (described later) showing the notification content 121 on the display unit 15. The revision notification for the electrical equipment information 100 is a process for notifying the administrator that the electrical equipment information 100 needs to be revised. The administrator revises the electrical equipment information 100 corresponding to the electrical equipment name included in the revision notification to match the components after the maintenance work with the components included in the electrical equipment information 100. If the drawings, etc. related to the electrical equipment information 100 are paper, the administrator refers to the notification screen 120 displayed on the display unit 15 to find and revise the drawings, etc. related to the electrical equipment information 100. If the drawings, etc. related to the electrical equipment information 100 are digitized, the notification content 121 includes a link to call up the digitized drawings, etc. This allows the administrator to find the necessary drawings, etc. by simply clicking the link.

Figure 7 is a diagram for explaining the notification content that the maintenance support device in embodiment 1 displays on the notification screen. The display unit 15 displays the notification screen 120 showing the notification content 121 according to an instruction from the display control unit 14.

The notification content 121 includes a message indicating that information such as the electrical equipment information 100 needs to be revised, such as an "information revision notification." The notification content 121 also includes the name of the electrical equipment to be revised, the reason why the electrical equipment information 100 needs to be revised, and a record of maintenance work to be referred to by the administrator.

The name of the electrical equipment to be revised is the name of the electrical equipment set by the determination unit 12 based on the component part information 102. Notification content 121 in Figure 7 shows a case where the name of the electrical equipment to be revised is P building electrical equipment. Notification content 121 in Figure 7 also shows a case where the reason for the need to revise the electrical equipment information 100 is the implementation of maintenance work.

The reference maintenance work record, which is a record of maintenance work that the administrator can refer to, includes the date of the maintenance work, the work target name of the component part for which the maintenance work was performed, the content of the maintenance work, etc. The work target name is the name of the component part set by the determination unit 12 based on the component part information 102. In the notification content 121 of Figure 7, the work target name in the reference maintenance work record is distribution board DA. The reference maintenance work record is created based on the maintenance information 201.

Next, the revision notification process of the electrical equipment information 100 by the maintenance support device 1 will be described using the flowchart shown in Figure 8. Figure 8 is a flowchart showing the processing procedure of the revision notification process of the electrical equipment information by the maintenance support device in embodiment 1.

Maintenance information 201 is input to the input unit 11 by the maintenance worker who performed the maintenance work. The input unit 11 accepts the maintenance information 201 (step S10).

Next, the judgment unit 12 receives the maintenance information 201 from the input unit 11 and detects whether the revision check column included in the maintenance information 201 has been checked (step S11). If there is a check (step S11, Yes), the judgment unit 12 judges that revision is necessary. If there is no check (step S11, No), the judgment unit 12 judges that there is no need for revision and terminates the notification process.

Next, the determination unit 12 extracts the work object name from the maintenance information 201 that has been determined to require revision. The determination unit 12 then compares the work object name with the component part information 102 to extract a component part that corresponds to the work object name from the component part information 102. The determination unit 12 sets the name of the electrical equipment that includes the extracted component part as the revision target (step S12).

For example, when the determination unit 12 extracts a switchboard DA as the name of the work target from the maintenance information 201, it selects the P building electrical equipment, which is the name of the electrical equipment that includes the switchboard DA, from the component information 102 and sets the revision target. The determination unit 12 sends the set name of the electrical equipment to be revised and the maintenance information 201 to the notification creation unit 13.

The notification creation unit 13 receives the name of the electrical equipment to be revised and the maintenance information 201 from the judgment unit 12, and creates, for example, the notification content 121 shown in Figure 7 based on the electrical equipment name and the maintenance information 201 (step S13).

The display control unit 14 receives the notification content 121 from the notification creation unit 13 and displays the notification screen 120 on the display unit 15 (step S14).

For example, when maintenance work is performed on an electric power consumer facility 3, the wiring or layout within the electric power consumer facility 3 may be changed. In this case, it is desirable to also modify the electrical equipment information 100, which contains information on electrical drawings such as wiring diagrams or layout diagrams. This is because unmodified electrical equipment information 100 may result in operational problems such as higher costs for investigating the actual situation of electrical equipment construction and delayed recovery when a problem occurs. The maintenance support device 1 of embodiment 1 automatically detects that the electrical equipment information 100 needs to be revised due to changes in the electrical equipment caused by maintenance work, etc., and notifies the administrator of the electrical equipment information 100 that needs to be revised.

In addition, in embodiment 1, the maintenance support device 1 determines whether or not revision of the electrical equipment information 100 is necessary based on the maintenance information 201 and the component information 102, so the electrical equipment information 100 and the load information 101 are not necessarily required.

Figure 9 is a diagram showing an example of the hardware configuration of the maintenance support device according to embodiment 1. As shown in Figure 9, the maintenance support device 1 can be realized by a processor 601, a memory 602, an input device 603, and a display 604.

The processor 601 is an example of a processing circuit. Examples of the processor 601 are a CPU (also called a central processing unit, processing unit, arithmetic unit, microprocessor, microcomputer, or DSP (Digital Signal Processor)) or a system LSI (Large Scale Integration). Examples of the memory 602 are a RAM (Random Access Memory) and a ROM (Read Only Memory).

The processor 601, memory 602, input device 603, and display 604 can transmit and receive information to each other, for example, via a bus 605. The input unit 11 is realized by the input device 603. The display unit 15 is realized by the display 604. The equipment information database 16 is realized by the memory 602.

The maintenance support device 1 is realized by the processor 601 reading and executing a computer-executable maintenance support program for executing the operations of the maintenance support device 1 stored in the memory 602. The maintenance support program, which is a program for executing the operations of the maintenance support device 1, can also be said to cause a computer to execute the procedures or methods of the maintenance support device 1.

The input device 603 accepts the maintenance information 201 and sends it to the processor 601. The memory 602 stores the maintenance support program, the electrical equipment information 100, the load information 101, and the component information 102.

The processor 601 executes the functions of the judgment unit 12, the notification creation unit 13, and the display control unit 14 by reading and executing the maintenance support program stored in the memory 602. That is, the maintenance support program executed by the maintenance support device 1 has a modular configuration including the judgment unit 12, the notification creation unit 13, and the display control unit 14, which are loaded onto the main memory device and generated on the main memory device.

The maintenance assistance program may be provided as a computer program product in the form of an installable or executable file stored on a computer-readable storage medium. The maintenance assistance program may also be provided to the maintenance assistance device 1 via a network such as the Internet. Note that some of the functions of the maintenance assistance device 1 may be realized by dedicated hardware such as a dedicated circuit, and some by software or firmware.

As described above, the maintenance support device 1 according to the first embodiment includes the determination unit 12 and the notification creation unit 13. The determination unit 12 determines whether or not the electrical equipment information 100 related to the electrical equipment needs to be revised based on the maintenance information 201. If the electrical equipment information 100 needs to be revised, the determination unit 12 extracts the work target name from the maintenance information 201 and sets it as the work target name to be revised. The determination unit 12 compares the work target name with the component information 102 and determines the electrical equipment name to be revised. The notification creation unit 13 creates notification content 121 in which the electrical equipment name and the work target name to be revised are described based on the electrical equipment name and the component information 102. The display control unit 14 receives the notification content 121 from the notification creation unit 13 and displays the notification screen 120 showing the notification content 121 on the display unit 15. This allows the maintenance support device 1 to present the electrical equipment information 100 that needs to be revised according to the maintenance work to the manager of the electrical equipment.

Embodiment 2.
Next, a second embodiment will be described with reference to Figures 10 and 11. The maintenance support device 1 of the second embodiment determines whether or not the electrical equipment information 100 and the load information 101 need to be revised based on the maintenance information 202 , and issues a revision notice for the electrical equipment information 100 and the load information 101 based on the determination result. The revision notice for the electrical equipment information 100 and the load information 101 is a process of notifying an administrator that the electrical equipment information 100 and the load information 101 need to be revised.

The configuration of the maintenance support device 1 in embodiment 2 is the same as the configuration of the maintenance support device 1 in embodiment 1, so its description is omitted.

The maintenance support device 1 of embodiment 2 determines whether or not revision of the electrical equipment information 100 and the load information 101 is necessary based on the maintenance information 202 , and if revision is necessary, issues a notification requesting revision of the electrical equipment information 100 and the load information 101.

In the following explanation, the explanation of processes similar to those performed by the maintenance support device 1 in embodiment 1 will be omitted, and the explanation will focus on processes that are different from those performed by the maintenance support device 1 in embodiment 1.

Figure 10 is a diagram showing an example of maintenance information input to the maintenance support device of embodiment 2. Maintenance information 202, like maintenance information 201, includes a work date, the name of the work object, the work content, and a revision check column. Maintenance information 202 in Figure 10 shows a case in which the name of the work object is air conditioner A1, the work content is replacement due to deterioration, and the air conditioner is changed to a small air conditioner (current 20A).

In embodiment 2, the load equipment 9 has been changed due to the replacement of the air conditioner A1, and in addition to the electrical equipment information 100, the load information 101 also needs to be revised.

The maintenance support device 1 of the second embodiment executes a revision notification process to the administrator using the same processing procedure as the maintenance support device 1 of the first embodiment described in FIG. 8. In the second embodiment, the input unit 11 accepts the maintenance information 202 (step S10). The judgment unit 12 judges whether or not the revision check column included in the maintenance information 202 is checked (step S11). If there is a check (step S11, Yes), the judgment unit 12 judges that revision is necessary. If there is no check (step S11, No), the judgment unit 12 judges that there is no need for revision and terminates the notification process.

Next, the determination unit 12 extracts the work object name from the maintenance information 202 that has been determined to require revision. The determination unit 12 then compares the work object name with the component information 102 to extract a component corresponding to the work object name from the component information 102. Since the work object name here is the name of the load equipment 9 among the components, the determination unit 12 extracts the load equipment 9 corresponding to the work object name from the component information 102. The determination unit 12 also extracts the name of the electrical equipment to which the extracted load equipment 9 belongs from the component information 102.

The judgment unit 12 sets the extracted load equipment 9 and electrical equipment name as the revision targets (step S12).

The notification creation unit 13 receives the name of the electrical equipment and the name of the load equipment to be revised and the maintenance information 202 from the judgment unit 12, and creates, for example, the notification content 123 described below (step S13).

The display control unit 14 receives the notification content 123 from the notification creation unit 13 and displays the notification screen 122 described below on the display unit 15 (step S14).

Figure 11 is a diagram for explaining notification contents that the maintenance support device according to the second embodiment displays on the notification screen. Note that, among the information included in the notification contents 123 shown in Figure 11, information that is similar to the information included in the notification contents 121 described in Figure 7 will not be described again.

The display unit 15 displays a notification screen 122 showing the notification content 123 in accordance with instructions from the display control unit 14.

The notification content 123 includes a message indicating that revisions are required for the electrical equipment information 100 and the load information 101. The notification content 123 also includes the name of the electrical equipment to be revised, the name of the load equipment to be revised, the reason why revisions are required for the electrical equipment information 100 and the load information 101, and a reference maintenance work record to be referred to by the administrator.

The name of the load equipment to be revised is the name of the load equipment 9 set by the determination unit 12 based on the component part information 102. Notification content 123 in FIG. 11 shows a case where the name of the electrical equipment to be revised is P building electrical equipment, and the name of the load equipment to be revised is air conditioner A1. Notification content 123 in FIG. 11 also shows a case where the reason for the need to revise the electrical equipment information 100 and the load information 101 is the implementation of maintenance work.

The reference maintenance work record, which is a record of maintenance work that the administrator can refer to, includes the date of the maintenance work, the name of the work object on which the maintenance work was performed, the content of the maintenance work, etc. The work object name is the work object name set by the determination unit 12 based on the component part information 102. In the notification content 123 of Figure 11, the work object name in the reference maintenance work record is air conditioner A1.

In addition, in embodiment 2, the maintenance support device 1 determines whether or not revision of the electrical equipment information 100 is necessary based on the maintenance information 202 and the component information 102, so the electrical equipment information 100 and the load information 101 are not necessarily required.

As described above, the maintenance support device 1 according to the second embodiment includes the determination unit 12 and the notification creation unit 13. The determination unit 12 determines whether or not the electrical equipment information 100 and the load information 101 need to be revised based on the maintenance information 202. If the electrical equipment information 100 and the load information 101 need to be revised, the determination unit 12 extracts the work object name from the maintenance information 202 and sets it as the work object name to be revised. The determination unit 12 compares the work object name with the component information 102 and determines the load equipment name and electrical equipment name to be revised. The notification creation unit 13 creates the notification content 123 based on the load equipment name, the electrical equipment name, and the component information 102. The display control unit 14 receives the notification content 123 from the notification creation unit 13 and displays the notification screen 122 showing the notification content 123 on the display unit 15. This allows the maintenance support device 1 to present the electrical equipment information 100 and the load information 101 that need to be revised according to the maintenance work to the manager of the electrical equipment.

Embodiment 3.
Next, a third embodiment will be described with reference to Fig. 12 to Fig. 15. The maintenance support device of the third embodiment compares a wiring diagram written in the maintenance information by a maintenance worker with a wiring diagram included in the electrical equipment information 100 to determine whether or not the electrical equipment information 100 needs to be revised.

Figure 12 is a diagram showing an example of the configuration of a maintenance support device according to embodiment 3. Among the components in Figure 12, components that achieve the same functions as those in the maintenance support device 1 of embodiment 1 shown in Figure 2 are given the same reference numerals, and duplicated explanations will be omitted.

The maintenance support device 1A according to the third embodiment differs from the maintenance support device 1 according to the first embodiment in that it uses a wiring diagram included in the maintenance information to determine whether or not the electrical equipment information 100 needs to be revised, and if it is determined that a revision is necessary, it issues a revision notification. The maintenance support device 1A issues a revision notification when the wiring diagram included in the maintenance information differs from the wiring diagram included in the electrical equipment information 100.

As shown in Fig. 12, the maintenance support device 1A includes an input unit 11, an equipment information database 16, a determination unit 12, a notification creation unit 13, a display control unit 14, a display unit 15, an acquisition unit 17, and a comparison unit 18. The equipment information database 16 included in the maintenance support device 1A stores information similar to that of the equipment information database 16 included in the maintenance support device 1.

Maintenance information containing maintenance work records is input to the input unit 11 of the maintenance support device 1A. Figure 13 is a diagram showing an example of maintenance information input to the maintenance support device according to the third embodiment.

Maintenance information 203 includes the date of work, the name of the work object, the work content, and a wiring diagram. The wiring diagram included in electrical equipment information 100 is the first wiring diagram, and the wiring diagram included in maintenance information 203 is the second wiring diagram. The wiring diagram included in maintenance information 203 includes input information 110 that is input by hand or the like by a maintenance worker during maintenance work. The input information 110 in maintenance information 203 shown in Figure 13 is air conditioner A3.

The acquisition unit 17 receives the maintenance information 203 input to the input unit 11, and extracts the work object name from the maintenance information 203. The acquisition unit 17 compares the work object name extracted from the maintenance information 203 with the components included in the component information 102. The acquisition unit 17 extracts components that match the work object name from the component information 102, and acquires the electrical equipment information 100 corresponding to the extracted components from the equipment information database 16.

When the work object name extracted from the maintenance information 203 matches the load equipment 9 included in the component information 102, the information acquired by the acquisition unit 17 from the equipment information database 16 is the electrical equipment information 100 and the load information 101. In the case of the maintenance information 203 shown in FIG. 13, the work object name is the switchboard DA, so the acquisition unit 17 acquires the electrical equipment information 100 from the equipment information database 16.

The comparison unit 18 receives the maintenance information 203 and the electrical equipment information 100 from the acquisition unit 17, and compares the wiring diagram included in the maintenance information 203 with the wiring diagram included in the electrical equipment information 100. At this time, the comparison unit 18 reads out the wiring diagram of the maintenance information 203 and the wiring diagram of the electrical equipment information 100 as PDF (Portable Document Format) data, and inputs the PDF data into PDF difference extraction software (e.g., Acrobat (registered trademark)). The comparison unit 18 detects differences in the wiring diagrams by performing a comparison process of the wiring diagrams using the PDF difference extraction software.

When input information 110 is input to the wiring diagram of maintenance information 203 during maintenance work, a difference occurs between the wiring diagram of maintenance information 203 and the wiring diagram of electrical equipment information 100, and comparison unit 18 extracts this difference. That is, comparison unit 18 determines the presence or absence of input information 110 input during maintenance work based on the results of the comparison process of the wiring diagrams. Comparison unit 18 sends information indicating the difference in the wiring diagrams to determination unit 12 as wiring diagram difference information.

The determination unit 12 receives the wiring diagram difference information. The determination unit 12 determines whether or not the electrical equipment information 100 needs to be revised based on the wiring diagram difference information. When the work object name extracted from the maintenance information 203 matches the load equipment 9 included in the component information 102, the determination unit 12 determines whether or not the electrical equipment information 100 and the load information 101 need to be revised based on the wiring diagram difference information.

If the wiring diagram in the maintenance information 203 contains information that was input during maintenance work, the determination unit 12 determines that the electrical equipment information 100 needs to be revised. The determination unit 12 identifies the electrical equipment information 100 that needs to be revised based on the wiring diagram difference information.

The notification creation unit 13, the display control unit 14, and the display unit 15 of the maintenance support device 1A have the same functions as the notification creation unit 13, the display control unit 14, and the display unit 15 of the maintenance support device 1, and execute the same processes. Note that the maintenance support device 1A has the same hardware configuration as the maintenance support device 1 described in the first embodiment.

In the following explanation, the explanation of processes similar to those performed by the maintenance support device 1 in embodiment 1 will be omitted, and the explanation will focus on processes that are different from those performed by the maintenance support device 1 in embodiment 1.

Figure 14 is a diagram for explaining notification contents that the maintenance support device according to the third embodiment displays on the notification screen. Note that, among the information included in the notification contents 125 shown in Figure 14, information that is similar to the information included in the notification contents 121 described in Figure 7 will not be described again.

The display unit 15 displays a notification screen 124 showing the notification content 125 in accordance with instructions from the display control unit 14.

Notification content 125 includes a message indicating that electrical equipment information such as electrical equipment information 100 needs to be revised. Notification content 125 also includes the name of the electrical equipment to be revised, the reason that electrical equipment information 100 needs to be revised, and a reference maintenance work record for the administrator to refer to. Notification content 125 also includes a wiring diagram that is the same as the wiring diagram in the latest maintenance information 203. In other words, if the wiring diagram in maintenance information 203 contains input information 110 that was entered during maintenance work, notification content 125 includes a wiring diagram with this input information 110 written on it.

The display unit 15 displays a notification screen 124 showing the notification content 125 in a manner that enables identification of which information the input information 110 is among the information contained in the notification content 125.

Next, the revision notification process of the electrical equipment information 100 by the maintenance support device 1A will be described using the flowchart shown in Figure 15. Figure 15 is a flowchart showing the processing procedure of the revision notification process of the electrical equipment information by the maintenance support device according to the third embodiment.

Maintenance information 203 is input to the input unit 11 by the maintenance worker who performed the maintenance work. The input unit 11 accepts the maintenance information 203 (step S10).

Next, the acquisition unit 17 receives the maintenance information 203 from the input unit 11 and extracts the work object name contained in the maintenance information 203. Furthermore, the acquisition unit 17 extracts components that match the work object name from the component information 102. Then, the acquisition unit 17 acquires the electrical equipment information 100 corresponding to the extracted components from the equipment information database 16 (step S21).

Next, the comparison unit 18 receives the maintenance information 203 and the electrical equipment information 100 from the acquisition unit 17, extracts and compares the wiring diagram contained in the maintenance information 203 and the wiring diagram contained in the electrical equipment information 100 (step S22).

The comparison unit 18 sends wiring diagram difference information indicating the difference between the wiring diagrams to the determination unit 12. The determination unit 12 determines whether or not there is a difference between the wiring diagrams based on the wiring diagram difference information (step S23). That is, the determination unit 12 determines whether or not the electrical equipment information 100 needs to be revised.

If there is a difference in the wiring diagram (step S23, Yes), the determination unit 12 determines that it is necessary to revise the electrical equipment information 100. If it is necessary to revise the electrical equipment information 100, the maintenance support device 1A executes the processing of steps S12 to S14 described in the first to third embodiments.

That is, the determination unit 12 extracts the work object name from the maintenance information 203, and extracts the component parts corresponding to the work object name from the component parts information 102. The determination unit 12 sets the name of the electrical equipment including the extracted component parts as the revision target (step S12).

The notification creation unit 13 receives the name of the electrical equipment to be revised and the maintenance information 203 from the judgment unit 12, and creates, for example, the notification content 125 shown in Figure 14 (step S13).

The display control unit 14 receives the notification content 125 from the notification creation unit 13 and displays the notification screen 124 on the display unit 15 (step S14). If there is no difference in the wiring diagram (step S23, No), the determination unit 12 determines that revision is not necessary and terminates the notification process.

In addition, in embodiment 3, the maintenance support device 1A determines whether or not revision of the electrical equipment information 100 is necessary based on the maintenance information 203, component information 102, and electrical equipment information 100, so the load information 101 is not necessarily required .

As described above, the maintenance support device 1A according to the third embodiment includes an acquisition unit 17, a comparison unit 18, and a determination unit 12. The acquisition unit 17 acquires the wiring diagram of the maintenance information 203 that has been changed by the maintenance work and the wiring diagram of the electrical equipment information 100 registered in the equipment information database 16. The comparison unit 18 compares the wiring diagram of the maintenance information 203 with the wiring diagram of the electrical equipment information 100 to extract the differences in the wiring diagrams. If there is a difference in the wiring diagram, the determination unit 12 determines that the electrical equipment information 100 needs to be revised. This allows the maintenance support device 1A to present the electrical equipment information 100 that needs to be revised to the administrator without requiring the maintenance worker to input a revision check in the revision check field.

In addition, when the equipment input as the input information 110 is a load equipment 9 such as an air conditioner A3 , the maintenance support device 1A can present the electrical equipment information 100 and load information 101 that require revision to the administrator without having the maintenance worker enter a revision check in the revision check column.

Embodiment 4.
Next, a fourth embodiment will be described with reference to Fig. 16 to Fig. 20. The maintenance support device of the fourth embodiment determines whether or not the electrical equipment information 100 needs to be revised based on an image of the work target equipment, which is the electrical equipment that is the target of work and is the equipment to be maintained.

Figure 16 is a diagram showing an example of the configuration of a maintenance support device according to embodiment 4. Among the components in Figure 16, components that achieve the same functions as those in the maintenance support device 1 of embodiment 1 shown in Figure 2 are given the same reference numerals, and duplicated explanations will be omitted.

The maintenance support device 1B according to the fourth embodiment extracts character information indicating the names of components, etc., from maintenance information including an image of the equipment to be worked on. The maintenance support device 1B differs from the maintenance support device 1 according to the first embodiment in that it uses the extracted character information to determine whether revision of the electrical equipment information 100 is necessary, and issues a revision notification if it is determined that revision is necessary. The maintenance support device 1B issues a revision notification of the electrical equipment information 100 if the components, etc. corresponding to the extracted character information differ from the components included in the component information 102.

As shown in Figure 16, the maintenance support device 1B includes an input unit 11, an equipment information database 16, a judgment unit 12, a notification creation unit 13, a display control unit 14, and a display unit 15. The maintenance support device 1B also includes an imaging unit 19 and an image analysis unit 20. The equipment information database 16 included in the maintenance support device 1B stores the same information as the equipment information database 16 included in the maintenance support device 1.

An example of the imaging unit 19 is a camera that captures a photograph as an image. The imaging unit 19 may be a digital camera or a camera provided in a mobile terminal such as a smartphone. The imaging unit 19 generates an image of the equipment to be worked on and sends it to the input unit 11.

Images of the equipment to be worked on, sent from the imaging unit 19, are input to the input unit 11 of the maintenance support device 1B. In addition, maintenance information is input to the input unit 11 by the maintenance worker who performed the maintenance work. This maintenance information is information from which the wiring diagram has been removed from the maintenance information 203 described in FIG. 13 of embodiment 3. The input unit 11 accepts the maintenance information from the maintenance worker. The input unit 11 attaches an image captured by the imaging unit 19 to the maintenance information input by the maintenance worker, thereby generating maintenance information 204, described below, that includes the image.

Note that an image may be attached to the maintenance information 204 input by the maintenance worker. In this case, the image is attached to the maintenance information 204 by the maintenance worker.

Figure 17 is a diagram showing an example of maintenance information generated by the input unit of the maintenance support device according to embodiment 4. The maintenance information 204 includes the date of work, the name of the work target, the work content, and an image of the work target equipment captured by the imaging unit 19. Figure 17 shows a case in which the work target is a switchboard DA, and an image of the work target equipment including the switchboard DA is captured by the imaging unit 19.

The image analysis unit 20 receives the maintenance information 204 from the input unit 11 and analyzes the image captured by the imaging unit 19. The components included in the equipment to be worked on have text information indicating the names of the components affixed to them in advance using a label writer such as Tepra (registered trademark). Therefore, the image captured by the imaging unit 19 includes a label indicating the text information.

For images containing labels indicating text information, the image analysis unit 20 uses a character recognition application (e.g., Google Lens (registered trademark)) to read the text information contained in the image and convert it into text data.

The determination unit 12 receives from the image analysis unit 20 the text data that the image analysis unit 20 extracts by analyzing the images included in the maintenance information 204, together with the maintenance information 204. The determination unit 12 also acquires the component information 102 from the equipment information database 16. The determination unit 12 compares the text data with the component information 102, and determines whether or not the electrical equipment information 100 needs to be revised.

For example, in the case of the maintenance information 204 shown in Figure 17, the text data that the determination unit 12 receives from the image analysis unit 20 includes the names of the switchboard DA, high-voltage substation equipment H1, air conditioner A1, air conditioner A2, and air conditioner A3. Of the components that correspond to these text data, there is no component in the component information 102 that corresponds to the text data for air conditioner A1, so the determination unit 12 determines that there is a difference in the components. In addition, the electrical equipment that corresponds to these text data is electrical equipment included in the P-building electrical equipment, so the determination unit 12 sets the name of the electrical equipment that is the subject of the revision notification to the P-building electrical equipment.

The notification creation unit 13, display control unit 14, and display unit 15 provided in the maintenance support device 1B have similar functions to the notification creation unit 13, display control unit 14, and display unit 15 provided in the maintenance support device 1, and perform similar processing.

In the following explanation, the explanation of processes similar to those performed by the maintenance support device 1 in embodiment 1 will be omitted, and the explanation will focus on processes that are different from those performed by the maintenance support device 1 in embodiment 1.

Figure 18 is a diagram for explaining notification contents that the maintenance support device according to the fourth embodiment displays on the notification screen. Note that, among the information included in the notification contents 127 shown in Figure 18, information that is similar to the information included in the notification contents 121 described in Figure 7 will not be described again.

The display unit 15 displays a notification screen 126 showing the notification content 127 in accordance with instructions from the display control unit 14.

The notification content 127 includes a message indicating that information on electrical equipment, such as electrical equipment information 100, needs to be revised. The notification content 127 also includes the name of the electrical equipment to be revised, the reason why the electrical equipment information 100 needs to be revised, a reference maintenance work record to be referred to by the administrator, and the like. The notification content 127 also includes an image of the equipment to be worked on, captured by the imaging unit 19.

Next, the revision notification process of the electrical equipment information 100 by the maintenance support device 1B will be described using the flowchart shown in Figure 19. Figure 19 is a flowchart showing the processing procedure of the revision notification process of the electrical equipment information by the maintenance support device according to the fourth embodiment.

The imaging unit 19 of the maintenance support device 1B captures an image of the target equipment for which maintenance work has been performed (step S31). The image of the target equipment for which maintenance work has been performed sent from the imaging unit 19 is input to the input unit 11.

In addition, the maintenance information before the image is attached is input to the input unit 11 by the maintenance worker who performed the maintenance work. The input unit 11 accepts the maintenance information before the image is attached from the maintenance worker (step S10). The input unit 11 generates maintenance information 204 with the image by attaching the image captured by the imaging unit 19 to the maintenance information input by the maintenance worker.

Next, the image analysis unit 20 receives the security information 204 from the input unit 11 and analyzes the image attached to the security information 204 (step S32). For an image that includes a label indicating text information, the image analysis unit 20 reads the characters contained in the image using a character recognition application and converts the characters into text data.

The judgment unit 12 receives maintenance information 204 from the image analysis unit 20. The judgment unit 12 also receives from the image analysis unit 20 text data extracted by the image analysis unit 20 by analyzing the image. The judgment unit 12 also acquires component information 102 from the equipment information database 16. The judgment unit 12 compares the text data with the component information 102. The judgment unit 12 compares the component indicated by the text data with the component included in the component information 102.

The determination unit 12 determines whether there is a difference between the components indicated by the text data and the components included in the component information 102 (step S33). In other words, the determination unit 12 determines whether the electrical equipment information 100 needs to be revised.

If there is a difference in the components (step S33, Yes), the judgment unit 12 judges that the electrical equipment information 100 needs to be revised. If there is a difference in the load equipment 9 among the components, the judgment unit 12 judges that the electrical equipment information 100 and the load information 101 need to be revised. After this, the maintenance support device 1B executes the processing of steps S12 to S14 described in the first and second embodiments.

If there are no differences in the components (step S33, No), the judgment unit 12 determines that revision is not necessary and terminates the notification process.

In the fourth embodiment, since the maintenance support device 1B determines whether or not the electrical equipment information 100 needs to be revised based on the maintenance information 204 and the component information 102 , the electrical equipment information 100 and the load information 101 are not necessarily required .

Figure 20 is a diagram showing an example of the hardware configuration of a maintenance support device according to embodiment 4. Note that among the components in Figure 20, components that achieve the same functions as those in the hardware configuration of the maintenance support device 1 according to embodiment 1 shown in Figure 9 are given the same reference numerals, and duplicated explanations will be omitted.

20, the maintenance support device 1B can be realized by a processor 601, a memory 602, an input device 603, a display 604, and an imaging device 606. The imaging unit 19 is realized by the imaging device 606, which is a device that captures an image.

The processor 601 of the maintenance support device 1B reads out and executes the maintenance support program stored in the memory 602, thereby executing the functions of the image analysis unit 20, the judgment unit 12, the notification creation unit 13, and the display control unit 14. That is, the maintenance support program executed by the maintenance support device 1B has a modular configuration including the image analysis unit 20, the judgment unit 12, the notification creation unit 13, and the display control unit 14, which are loaded onto the main memory device and generated on the main memory device.

As described above, the maintenance support device 1B according to the fourth embodiment includes an imaging unit 19, an image analysis unit 20, and a determination unit 12. The imaging unit 19 acquires an image of the equipment to be worked on. The image analysis unit 20 analyzes the image attached to the maintenance information 204, reads characters indicating the names of the components from the image, and converts them into text data. The determination unit 12 compares the components indicated by the text data with the components included in the component information 102, and determines that the electrical equipment information 100 needs to be revised if there is a difference between the components. This allows the maintenance support device 1B to present the electrical equipment information 100 that needs to be revised to the administrator, without requiring the maintenance worker to enter a revision check in the revision check field.

In addition, if the component with the difference is a load equipment 9 such as an air conditioner A1, the maintenance support device 1B can present the electrical equipment information 100 and load information 101 that require revision to the administrator without having the maintenance worker input a revision check in the revision check column.

Embodiment 5.
Next, a fifth embodiment will be described with reference to Figures 21 to 24. The maintenance support device of the fifth embodiment determines whether or not it is necessary to confirm that the electrical equipment has been changed, based on the revised electrical equipment information and the pre-revision electrical equipment information 100. When it is determined that it is necessary to confirm that the electrical equipment has been changed, the maintenance support device of the fifth embodiment creates and outputs notification content indicating that it is necessary to confirm that the electrical equipment has been changed.

Figure 21 is a diagram showing an example of the configuration of a maintenance support device according to embodiment 5. Among the components in Figure 21, components that achieve the same functions as those in the maintenance support device 1A according to embodiment 3 shown in Figure 12 are given the same reference numerals, and duplicated explanations will be omitted.

The maintenance support device 1C of embodiment 5 differs from the maintenance support device 1A of embodiment 3 in that it extracts the corrections to the electrical equipment information 100 by comparing the revised electrical equipment information 100 with the electrical equipment information 100 before the revision, and notifies the administrator of the corrections.

As shown in FIG. 21, the maintenance support device 1C includes an input unit 11, an equipment information database 16, a judgment unit 12, a notification creation unit 13, a display control unit 14, a display unit 15, an acquisition unit 17, a comparison unit 18, and an information update unit 21.

The electrical equipment information 103 revised by the administrator through corrections is input to the input unit 11. The input unit 11 accepts the electrical equipment information 103 and sends it to the information update unit 21.

The information update unit 21 receives the revised electrical equipment information 103 from the input unit 11 and stores the revised electrical equipment information 103 in the equipment information database 16. The information update unit 21 also sends the revised electrical equipment information 103 to the acquisition unit 17. The maintenance support device 1C has the same hardware configuration as the maintenance support device 1 described in the first embodiment.

In the following explanation, the explanation of the processing similar to the processing performed by the maintenance support device 1A in embodiment 3 will be omitted, and the explanation will focus on the processing that is different from the maintenance support device 1A in embodiment 3.

Figure 22 is a diagram showing an example of revised electrical equipment information input to the input section of the maintenance support device according to embodiment 5. Note that, among the information contained in the electrical equipment information 103 shown in Figure 22, information that is similar to the information contained in the electrical equipment information 100 described in Figure 4 will not be described again.

Compared to the electrical equipment information 100 before the revision, the revised electrical equipment information 103 has the component name Air Conditioner A3 added, the number of branch circuits on the distribution board DA has been changed from 2 to 3, and Air Conditioner A3 has been added to the wiring diagram.

The acquisition unit 17 receives the revised electrical equipment information 103 from the information update unit 21 and acquires the pre-revision electrical equipment information 100 from the equipment information database 16. The acquisition unit 17 sends the acquired electrical equipment information 100 and electrical equipment information 103 to the comparison unit 18.

The comparison unit 18 compares the electrical equipment information 100, which is the electrical equipment information before the revision, with the electrical equipment information 103, which is the electrical equipment information after the revision, and detects the difference between the electrical equipment information 100 and 103. Here, the comparison unit 18 detects the difference between the wiring diagrams by processing similar to the method described in the third embodiment. That is, the comparison unit 18 detects the difference between the wiring diagram included in the electrical equipment information 100 before the revision and the wiring diagram included in the electrical equipment information 103 after the revision. The comparison unit 18 sends information indicating the difference between the electrical equipment information 100 and 103 to the determination unit 12 as revision difference information.

The determination unit 12 receives the revision difference information. The determination unit 12 determines whether or not there is a difference between the electrical equipment information 100, 103 based on the revision difference information. If there is a difference between the electrical equipment information 100, 103, the determination unit 12 sends revision difference information indicating the difference between the electrical equipment information 100, 103 to the notification creation unit 13. The revision difference information is information indicating the revisions made from the electrical equipment information 100 to the electrical equipment information 103.

The notification creation unit 13 receives the judgment result sent from the judgment unit 12 and determines the notification content 131 described below. Specifically, the notification creation unit 13 cuts out the periphery of the revised part, including the position of the part judged to be the revised part based on the revision difference information, and creates the notification content 131 based on the cut-out area.

The notification creation unit 13 sends the created notification content 131 to the display control unit 14. The display control unit 14 receives the notification content 131 from the notification creation unit 13, and causes the display unit 15 to display a notification screen 130 (described below) showing the notification content 131. The display unit 15 displays the notification screen 130 showing the notification content 131 in accordance with instructions from the display control unit 14.

Figure 23 is a diagram for explaining notification contents that the maintenance support device according to the fifth embodiment displays on the notification screen. Note that, among the information included in the notification contents 131 in Figure 23, information that is similar to the information included in the notification contents 125 described in Figure 14 will not be described again.

Notification content 131 is information to notify that electrical equipment needs to be checked for modifications. Notification content 131 includes a message indicating that it is necessary to check whether the correct modifications have been made to the electrical equipment, such as an "equipment confirmation notification." Notification content 131 also includes the name of the electrical equipment to be checked, the reason that equipment confirmation is necessary to check the modifications to the electrical equipment, and the revised parts, which are information on the parts to be corrected that the administrator should refer to.

Notification content 131 also describes an area that includes the component that is the revised part of the wiring diagram described in the revised electrical equipment information 103 and the components surrounding this component. For example, if air conditioner A3 is added to electrical equipment information 100, notification content 131 describes distribution board DA and air conditioners A1 and A2, which are components surrounding air conditioner A3. That is, based on the revision difference information, notification creation unit 13 cuts out the area around air conditioner A3, including the position of air conditioner A3, which is the revised part, and creates notification content 131 based on the cut-out area.

The name of the electrical equipment to be checked for changes is the name of the electrical equipment having components included in the revision difference information created by the judgment unit 12. The name of the electrical equipment to be checked for changes is set by the judgment unit 12 based on the revision difference information and component information 102.

The notification content 131 in Fig. 23 shows a case where the name of the electrical equipment to be checked is the P building electrical equipment. The notification content 131 in Fig. 23 also shows a case where the reason for equipment check, which is to check whether the correct changes have been made to the electrical equipment, is a revision of the electrical equipment information 100.

The revisions contained in the notification content 131 include the names of the components contained in the revision difference information created by the judgment unit 12 and the specifications or product names corresponding to these component names.

Next, a facility confirmation notification process of the electrical facility information 100 and the load information 101 by the maintenance support device 1C will be described with reference to the flowchart shown in Fig. 24. Fig. 24 is a flowchart showing the processing procedure of the facility confirmation notification process by the maintenance support device according to the fifth embodiment.

The electrical equipment information 103 revised by the administrator is input to the input unit 11 of the maintenance support device 1C. The input unit 11 accepts the electrical equipment information 103 from the administrator (step S41).

Next, the information update unit 21 receives the revised electrical equipment information 103 from the input unit 11 and stores it in the equipment information database 16 (step S42).

The acquisition unit 17 receives the revised electrical equipment information 103 from the information update unit 21 and acquires the pre-revision electrical equipment information 100 from the equipment information database 16 (step S43).

After that, the maintenance support device 1C of the fifth embodiment executes steps S22 and S23 by the same processing procedure as that of the maintenance support device 1A of the third embodiment described in Fig. 15. That is, the comparison unit 18 receives the electrical equipment information 103 and the electrical equipment information 100 from the acquisition unit 17, and extracts and compares the wiring diagram included in the electrical equipment information 103 with the wiring diagram included in the electrical equipment information 100 (step S22).

The comparison unit 18 sends the revision difference information to the determination unit 12. The determination unit 12 determines whether or not there is a difference in the wiring diagram, etc. , based on the revision difference information (step S23). That is, the determination unit 12 determines whether or not it is necessary to check for changes in the electrical equipment.

If there is a difference in the wiring diagram (step S23, Yes), the determination unit 12 determines that it is necessary to check for changes to the electrical equipment. If it is necessary to check for changes to the electrical equipment, the maintenance support device 1C executes the processing of steps S12 to S14 described in embodiments 1 to 4.

That is, the determining unit 12 extracts the components from the revision difference information , and sets the name of the electrical equipment including the extracted components as the revision target (step S12).

In embodiments 1 to 4, the subject of revision was the name of the electrical equipment for which the electrical equipment information 100 was revised, whereas in embodiment 5, the subject of revision is the name of the electrical equipment for which the electrical equipment information 100 has been revised.

The notification creating unit 13 receives the name of the electrical equipment to be revised and the component parts from the determining unit 12, and creates, for example, the notification content 131 shown in Fig. 23 (step S13). This notification content 131 includes the revision points showing the differences in the wiring diagram.

The display control unit 14 receives the notification content 131 from the notification creation unit 13 and displays the notification screen 130 on the display unit 15 (step S14). If there is no difference in the wiring diagram (step S23, No), the determination unit 12 determines that there is no need to confirm the changes and ends the notification process.

In addition, in embodiment 5, since the maintenance support device 1C determines whether or not it is necessary to confirm changes to the electrical equipment based on the electrical equipment information 103 and the electrical equipment information 100, the load information 101 is not necessarily required .

As described above, the maintenance support device 1C according to the fifth embodiment includes an information update unit 21 and a comparison unit 18. The information update unit 21 receives the revised electrical equipment information 103 and stores it in the equipment information database 16. The comparison unit 18 compares the revised electrical equipment information 103 with the electrical equipment information 100 before revision, and determines that the electrical equipment needs to be checked if there is a difference. This enables the maintenance support device 1C to register the electrical equipment information 103 and present the corrections required to check whether the correct changes have been made to the electrical equipment.

The configurations shown in the above embodiments are merely examples, and may be combined with other known technologies, or the embodiments may be combined with each other. Also, parts of the configurations may be omitted or modified without departing from the spirit of the invention.
