For example, the maintenance plan generation unit 41 diagnoses the degree of deterioration of the equipment 110 from the result of periodic inspection, and performs maintenance so that the inspection, repair, or replacement is performed before the timing at which a failure or performance degradation is estimated. A plan may be generated.

  The maintenance plan generation unit 41 may generate a maintenance plan based on the diagnostic information acquired from each of the plurality of facilities 110 by the diagnostic information acquisition unit 310. For example, the maintenance plan generation unit 41 refers to the diagnosis information stored in the facility database 30 and the inspection result stored in the maintenance database 40 at the timing when the periodic report is output by the facility monitoring system 3. A maintenance plan may be generated by diagnosing the degree of deterioration.

  In addition, the maintenance plan generation unit 41 may determine the priority of maintenance among the plurality of facilities 110 based on the power state collected by the power monitoring unit 21 and the diagnostic information collected by the diagnostic information acquisition unit 310. For example, the maintenance plan generation unit 41 calculates the degree of deterioration of each facility 110 from the power state and diagnosis information for the plurality of facilities 110, and checks the facility 110 with the earlier timing at which failure or performance degradation is estimated, The priority may be determined so that repair or replacement is performed and the equipment 110 having no abnormality is postponed to inspection, repair or replacement. Instead of / in addition to this, the maintenance plan generation unit 41 calculates the severity or frequency of abnormality of the power abnormality from the collected power state, and uses the value to degrade each facility 110 calculated from the diagnostic information or the like. The priority may be determined by weighting the degree. The maintenance plan generation unit 41 may read the power state from the power monitoring database 20 and the diagnostic information from the equipment database 30, and may calculate the degree of deterioration, the degree of abnormality seriousness, etc. by multivariate analysis.

Thereby, the customer can grasp | ascertain the maintenance state of the installation 110. FIG. The display control unit 42 may output a maintenance history. Further, the display control unit 42 may output the equipment ledger stored in the maintenance database 40 or may output the maintenance plan generated by the maintenance plan generation unit 41.

[1-6. Management Department]
The management unit 5 manages a plurality of facilities 110 in an integrated manner, and may be a cloud server as an example. The management unit 5 includes an integrated database 50, a display control unit 51, a power state comparison unit 52, and a synchronization processing unit 53.

  The integrated database 50 links customer, area 100, and facility 110 identification information between the energy management system 2, the facility monitoring system 3, the maintenance system 4, and the facility management system 1. For example, the integrated database 50 stores the customer identification information and password in each of the energy management system 2, the facility monitoring system 3, and the maintenance system 4 in association with the customer identification information and password in the facility management system 1. . The integrated database 50 corresponds to the identification information of the area 100 and the facility 110 in each of the energy management system 2, the facility monitoring system 3 and the maintenance system 4, and the identification information of the area 100 and the facility 110 in the facility management system 1. Add and remember.

  The display control unit 51 causes the display device 510 to output the diagnostic information of the target facility 110 acquired by the diagnostic information acquisition unit 310. In addition to this, the display control unit 51 may maintain the logged-in state in the energy management system 2 and the facility monitoring system 3, preferably further in the maintenance system 4, and provide an integrated user interface for these systems.

  Here, the integrated user interface is an interface that enables each of the energy management system 2, the equipment monitoring system 3, and the maintenance system 4 to exchange information with the customer, and provides an integrated management environment. For example, the integrated user interface may be a multi-view graphical user interface (GUI) in which display screens by at least the energy management system 2, the facility monitoring system 3, and the maintenance system 4 are arranged. Details of the display contents of the integrated user interface will be described later with reference to FIGS.

  The power state comparison unit 52 compares the power state before and after repair or replacement of one facility 110 in the area 100 to which the one facility 110 belongs. For example, the power state comparison unit 52 may refer to the power monitoring database 20 and compare the power states at the timings before and after the repair or replacement for the area 100 including the repaired or replaced facility 110. The power state comparison unit 52 may provide the comparison result to the display control unit 51. Thereby, it is possible to determine whether or not the power state has been normalized by repair or replacement.

  The synchronization processing unit 53 synchronizes the correspondence relationship between the plurality of areas 100 and the plurality of facilities 110 between the power monitoring database 20 and the facility database 30, preferably between the maintenance database 40. For example, the synchronization processing unit 53 may synchronize when a customer logs into the facility management system 1. In addition, the synchronization processing unit 53 may be synchronized by updating the contents of each database to the latest information in response to an operation instruction from the customer when the customer adds, moves, or removes the equipment 110, or periodically. Good.

  According to the facility management system 1 described above, a facility monitoring trigger is generated in accordance with the monitoring result of the power state in each of the plurality of areas 100, and at least one facility 110 belonging to the target area 100 that has caused the trigger is generated. Diagnostic information is acquired. Therefore, using the diagnostic information of the equipment 110 in the area 100 where the abnormality has occurred in the power state, the equipment 110 in which the abnormality has occurred can be identified at an early stage, and can be inspected, repaired or replaced. When the equipment 110 is operated again and an abnormality occurs in the power state, the equipment 110 in which the abnormality has occurred is also identified early, and is inspected, repaired, or replaced. Thus, since the equipment 110 can be operated in an appropriate state without abnormality, wasteful consumption of energy can be suppressed and consumption can be reduced.

[2. Operation of equipment management system]
FIG. 2 shows the operation of the facility management system 1 according to the present embodiment. In this operation, the facility database 30 has already stored the association of each of the plurality of facilities 110 to which of the plurality of areas 100.

  First, the display control unit 51 logs into each of the energy management system 2, the facility monitoring system 3, and the maintenance system 4 (step S11). For example, in response to receiving the customer's identification information and password input in the facility management system 1 from the customer, the display control unit 51 in each of the energy management system 2, the facility monitoring system 3, and the maintenance system 4 The identification information and password of the corresponding customer may be read from the integrated database 50 and logged into each system.

  Next, the synchronization processing unit 53 synchronizes the correspondence relationship between the plurality of areas 100 and the plurality of facilities 110 among the power monitoring database 20, the facility database 30, and the maintenance database 40 (step S13).

  Next, the display control unit 51 causes the display device 510 to start displaying the integrated user interface (step S15). Thereby, at least the display screens by the energy management system 2, the facility monitoring system 3, and the maintenance system 4 are displayed side by side, and information can be exchanged between each of these systems and the customer. For example, when one area 100 or facility 110 is selected by the customer in the integrated user interface, the display control unit 51 refers to the integrated database 50, and the energy management system 2 for the selected area 100 or facility 110, Identification information in each of the equipment monitoring system 3 and the maintenance system 4 is specified, and information associated with the identification information is read from the energy management system 2, the equipment monitoring system 3, and the maintenance system 4 and displayed on the display device 510.

  Here, in the display screen of the energy management system 2, the display control unit 51 may cause the display device 510 to output a screen indicating the power supply / demand relationship between the plurality of areas 100.

  Further, in the display screen of the facility monitoring system 3, the display control unit 51 may display a plurality of types of diagnosis information acquired by the diagnosis information acquiring unit 310 for one facility 110 using a plurality of windows. For example, the display control unit 51 may display diagnostic information such as temperature, internal resistance, voltage, and the like on separate windows for the battery as the facility 110.

  Next, the power monitoring unit 21 monitors the power state in each of the plurality of areas 100 (step S17). For example, the power monitoring unit 21 may monitor the power state of the equipment 110 belonging to each of the plurality of areas 100. The power monitoring unit 21 may monitor the power state using the power state sensor 101 for each area 100. The power monitoring unit 21 may detect an abnormality when the power consumption in one area 100 exceeds a preset upper limit value (rated power consumption as an example). In addition / alternatively, the power monitoring unit 21 may detect an abnormality in response to the power consumption being below the lower limit value.

  Here, the power state sensor 101 may transmit the measurement value to the power monitoring unit 21 in any format of text (CSV), mail, and digital input (DI). In the text format and the mail format, the measurement values within the measurement period are transmitted side by side. In this case, the power monitoring unit 21 analyzes the received content and generates time-series data of measurement values. For example, when any measurement value exceeds a reference threshold value or exceeds a certain period threshold value (instantaneous value) Instead, the abnormality may be detected by monitoring the time integral value). On the other hand, in the digital input format, a measurement value at one measurement timing is transmitted. In this case, the power monitoring unit 21 detects, for example, when the received measurement value fluctuates with respect to the previous measurement value with respect to the reference fluctuation range, or when fluctuations greater than the reference fluctuation range are continuously detected a predetermined number of times (for example, three times). In addition, an abnormality may be detected.

  Next, the power monitoring unit 21 determines whether there is an abnormality in the power state (step S19). When it is determined that there is no abnormality in the process of step S19 (S19; No), the power monitoring unit 21 proceeds to the process of step S17.

  If it is determined in step S19 that there is an abnormality (S19; Yes), the trigger generation unit 24 generates a facility monitoring trigger and transmits it to the facility monitoring system 3 (step S21). Thereby, according to the monitoring result of the electric power state in each of the plurality of areas 100, a trigger for facility monitoring is generated. For example, when a drill breaks or a cutting piece is caught in the equipment 110 that is a rotating machine in a machining center, an equipment monitoring trigger is generated in response to the detection of an abnormality in the power state.

  Here, the trigger includes the identification information of the target area that caused the trigger to be generated (identification information in the energy management system 2 as an example), the occurrence time and contents of the abnormality that caused the trigger to be generated, etc. May be included.

  The trigger generation unit 24 may transmit a trigger to the management unit 5. In response to receiving the trigger, the display control unit 51 of the management unit 5 may cause the display device 510 to output an alert screen that notifies the customer of the occurrence of the trigger. Details of the alert screen will be described later with reference to FIGS.

  Next, the equipment specifying unit 34 of the equipment monitoring system 3 uses the equipment database 30 to target at least one equipment 110 belonging to the target area 100 that has caused the trigger, that is, the area 100 in which an abnormality in the power state is detected. The equipment is specified (step S23). For example, the equipment specifying unit 34 refers to the integrated database 50, specifies identification information in the equipment monitoring system 3 for the target area 100, and is associated in the equipment database 30 with the area 100 indicated by the identification information. The at least one facility 110 may be specified as the target facility.

  The facility specifying unit 34 may select the target facility based on the diagnosis information acquired from each of the facilities 110 belonging to the target area 100.
