[0026] Next, a configuration of the first server 100A constituting the network system 1 according to the present embodiment will be described. Referring to Fig. 5, the first server 100A includes, as main components, a CPU (Central Processing Unit) 110, a memory 120, an operation unit 140, and a communication interface 160.

[0027] The CPU 110 controls each part of the first server 100A by executing a program stored in the memory 120. For example, the CPU 110 executes a program stored in the memory 120 and performs various processes, which will be described later, by referring to various data.

[0028] The memory 120 is realized by various RAMs (Random Access Memories), various ROMs (Read-Only Memories), etc., and may be included in the first server 100A, may be detachable from various interfaces of the first server 100A, or may be a recording medium of another device accessible from the first server 100A. The memory 120 stores programs executed by the CPU 110, data generated by execution of programs by the CPU 110, input data, other databases used for the service according to this embodiment, and the like.

[0029] For example, the memory 120 stores facility information data as shown in Fig. 6. The facility information data stores a facility ID, sensor information, main body information, resident information, personal information, information on the facility's own system, information on other sensors, information on other systems, and the like.

[0030] The facility ID is identification information for identifying a facility or business, and is used when accessing the second server 100B.

[0031] The sensor information is data stored as history, and is information of various sensors acquired from the second server 100B periodically or at any timing.

[0032] The main body information is data stored as history, and is information on the operating state and operation details of the electric device 200 that is periodically acquired from the second server 100B.

[0049] The memory 120 of the second server 100B stores, for each facility, for each electrical device 200 and for each part to be replaced, the number of parts that have reached the replacement time (1), and the number of parts that are within a predetermined period, such as two weeks, prior to the replacement time (2), as shown in the upper part of Fig. 3. In this embodiment, the number of replacement parts on the right side of the upper part of Fig. 3 is the sum of the number of parts that have already reached the replacement time (1) and the number of parts that will soon reach the replacement time (2).

[0050] The memory 120 of the second server 100B stores, for each facility, for each electrical device 200 and for each part to be maintained, the number of parts that have reached the maintenance time (1), and the number of parts that are within a predetermined period, such as two weeks, going back from the maintenance time (2), as shown in the lower part of Fig. 3. In this embodiment, the number of parts requiring maintenance on the right side of the lower part of Fig. 3 is the sum of the number of parts that have already reached the maintenance time (1) and the number of parts that will soon reach the maintenance time (2).

[0051] The memory 120 of the second server 100B stores, for each electrical device 200 grouped together from a plurality of facilities and for each part to be replaced, the number of parts that have reached the replacement time (1) and the number of parts that are within a predetermined period, such as one week, prior to the replacement time (2), as shown in the upper part of Fig. 4. In this embodiment, the number of replacement parts on the right side of the upper part of Fig. 4 is the sum of the number of parts that have already reached the replacement time (1) and the number of parts that will soon reach the replacement time (2).

[0052] The memory 120 of the second server 100B stores, for each electrical device 200 grouped together in a plurality of facilities and for each part to be maintained, the number of parts that have reached the maintenance time (1) and the number of parts that are within a predetermined period, such as one week, going back from the maintenance time (2), as shown in the lower part of Fig. 4. In this embodiment, the number of parts requiring maintenance on the right side of the lower part of Fig. 4 is the sum of the number of parts that have already reached the maintenance time (1) and the number of parts that will soon reach the maintenance time (2). <Information Processing of the Second Server 100B>

[0053] Next, information processing in the second server 100B will be described with reference to Fig. 12. The CPU 110 of the second server 100B according to the present embodiment executes the following processing in accordance with the program in the memory 120.

[0054] First, the CPU 110 receives driving information, operation information, sensor measurement information, and the like from the electric device 200 via the communication interface 160, and stores them as history in the memory 120 (step S100).

[0055] CPU 110 determines whether it is time to replace any part of target electric device 200, based on the operation time elapsed since the previous replacement time (step S102).

[0056] When it is time to replace any of the parts (YES in step S102), CPU 110 increases the number of parts to be replaced by one (step S104). In this embodiment, CPU 110 increases the number of parts to be replaced by one for the facility in which electrical device 200 is used, as shown in the center of the upper part of Fig. 3, and increases the number of parts to be replaced by one for the contractor, as shown in the center of the upper part of Fig. 4. Note that, in a case where the number on the right side does not include the number in the center, it is necessary to subtract one from the number on the right side of Fig. 3 or the number on the right side of Fig. 4 as the number of parts to be replaced soon.

[0057] CPU 110 refers to the data shown in FIG. 3 and determines whether or not the number of replacements of any part in the target facility has exceeded a first predetermined number, for example, 10 (step S106).

[0058] If the number of replacements of any part exceeds a predetermined number (YES in step S106), CPU 110 transmits the data shown in Fig. 3 to manager terminal 300 of the facility in question via communication interface 160 (step S108). As a result, CPU 310 of manager terminal 300 outputs a voice notification from speaker 370 and displays a notification message on display 330 based on the received data. CPU 310 displays the screen shown in the upper part of Fig. 3 on display 330 based on the operation of the manager. CPU 310 transmits a parts order command and displays a maintenance screen shown in the lower part of Fig. 3 based on the operation of the manager.

[0059] CPU 110 refers to the data shown in FIG. 4 and determines whether the total number of replacements of any part in a plurality of facilities exceeds a second predetermined number, for example, 100 (step S110).

[0060] When the total number of replacements of any part at a plurality of facilities exceeds a predetermined number (YES in step S110), CPU 110 transmits the data shown in FIG. 4 to contractor terminal 400 via communication interface 160 (step S112). As a result, CPU 410 of contractor terminal 400 outputs a voice notification from speaker 470 and displays a notification message on display 430 based on the received data. CPU 410 displays the screen shown in the upper part of FIG. 4 on display 430 based on the contractor's operation. CPU 410 displays the number of replacements for each facility and displays a maintenance screen shown in the lower part of FIG. 4 based on the contractor's operation.

[0061] If none of the parts are due for replacement (NO in step S102), CPU 110 determines whether any of the parts will need to be replaced in the near future, for example within one week, based on the elapsed operating time since the last replacement (step S122).

[0062] If any of the parts will soon reach the time for replacement (YES in step S122), CPU 110 increases the number of parts scheduled for replacement by one (step S124). In this embodiment, CPU 110 increases the number of parts scheduled for replacement by one for the facility in which electrical device 200 is used, as shown in the right end of the upper row of Fig. 3, and increases the number of parts scheduled for replacement by one for the contractor, as shown in the right end of the upper row of Fig. 4.

[0063] The CPU 110 refers to the data shown in FIG. 3 and determines whether or not the number of parts scheduled for replacement in the target facility has exceeded a third predetermined number, for example, 15 (step S126).

CPU 110 transmits a parts order command and displays a maintenance screen shown in the lower part of Fig. 3 based on the operation of the manager.

[0065] CPU 110 refers to the data shown in FIG. 4 and determines whether the total number of parts scheduled for replacement in a plurality of facilities exceeds a fourth predetermined number, for example, 150 (step S130).

[0066] When the total number of parts scheduled for replacement for a plurality of facilities exceeds a predetermined number (YES in step S130), CPU 110 transmits the data shown in FIG. 4 to contractor terminal 400 via communication interface 160 (step S132). As a result, CPU 410 of contractor terminal 400 outputs a voice notification from speaker 470 and displays a notification message on display 430 based on the received data. CPU 410 displays the screen shown in the upper part of FIG. 4 on display 430 based on the contractor's operation. CPU 410 displays the number of parts to be replaced for each facility and displays a maintenance screen shown in the lower part of FIG. 4 based on the contractor's operation.

[0067] If none of the parts will soon need to be replaced (NO in step S122), CPU 110 determines whether any of the parts need maintenance based on the elapsed operating time since the previous maintenance (step S142).

[0068] When it is time for maintenance of any part (YES in step S142), CPU 110 increases the number of maintenances for that part by one (step S144). In this embodiment, CPU 110 increases the number of maintenances for that part for the facility in which electrical device 200 is used as shown in the center of the lower part of Fig. 3 by one, and increases the number of maintenances for parts for the contractor as shown in the center of the lower part of Fig. 4 by one. Note that, in a case where the number on the right side does not include the number in the center, it is necessary to subtract one from the number on the right side of Fig. 3 or the number on the right side of Fig. 4 as the number of parts to be replaced soon.

[0069] CPU 110 refers to the data shown in FIG. 3 and determines whether or not the number of maintenance parts for the target facility has exceeded a first predetermined number, for example, 10 (step S146).

[0070] If the number of maintenance parts for any part exceeds a predetermined number (YES in step S146), CPU 110 transmits the data shown in FIG. 3 to manager terminal 300 of the facility in question via communication interface 160 (step S148). As a result, CPU 310 of manager terminal 300 outputs a voice notification from speaker 370 and displays a notification message on display 330 based on the received data. CPU 310 causes display 330 to display a screen shown in the lower part of FIG. 3 based on the operation of the manager. CPU 110 causes application for maintenance and display of a replacement screen shown in the upper part of FIG. 3 based on the operation of the manager.

[0071] CPU 110 refers to the data shown in FIG. 4 and determines whether the total number of maintenance requests for any part in a plurality of facilities exceeds a second predetermined number, for example, 100 (step S150).

[0072] When the total number of maintenances for any part for a plurality of facilities exceeds a predetermined number (YES in step S150), CPU 110 transmits the data shown in FIG. 4 to contractor terminal 400 via communication interface 160 (step S152). As a result, CPU 410 of contractor terminal 400 outputs a voice notification from speaker 470 and displays a notification message on display 430 based on the received data. CPU 410 displays a screen shown in the lower part of FIG. 4 on display 430 based on the contractor's operation. CPU 410 displays the number of maintenances for each facility and displays a replacement screen shown in the upper part of FIG. 4 based on the contractor's operation.

[0073] If the maintenance time has not yet arrived for any of the parts (NO in step S142), CPU 110 determines whether or not the time for maintenance will arrive for any of the parts in the near future, for example within one week, based on the elapsed operating time since the previous maintenance time (step S162).

[0074] If any part will soon reach the time for maintenance (YES in step S162), CPU 110 increases the number of parts scheduled for maintenance by one (step S164). In this embodiment, CPU 110 increases the number of parts scheduled for maintenance by one for the facility in which electrical device 200 is used, as shown in the right end of the lower half of Fig. 3, and increases the number of parts scheduled for maintenance by one for the contractor, as shown in the right end of the lower half of Fig. 4.
