Summary of the Invention

Problems to be Solved by the Invention

[0004] Here, when a plurality of facilities are connected to a main line, there is also a technology for performing power measurement on the main line and executing energy management. However, since power measurement is performed on a main line basis, it is impossible to detect an abnormality in the power consumption of each facility. At this time, by providing a power meter for all facilities, it is possible to identify which facility has a power abnormality. However, there is a problem that a large amount of power meters need to be introduced, the system also becomes large, and the cost increases significantly.

[0005] The present invention has been made to solve such problems, and provides an abnormal equipment identification system that can be constructed at low cost.

Means for Solving the Problems

[0006] The abnormal equipment identification system according to the present invention is an abnormal equipment identification system that identifies equipment where an abnormality has occurred in a plurality of pieces of equipment connected to each of a plurality of trunk lines, and comprises: a power consumption information acquisition unit that acquires power consumption on a trunk line basis; an operation information acquisition unit that acquires operation information for each of the plurality of pieces of equipment; and an abnormal equipment identification processing unit that identifies the trunk line where the power abnormality occurred based on the power consumption acquired by the power consumption information acquisition unit, and identifies the equipment where the power consumption abnormality occurred based on the power consumption of the identified trunk line and the operation information of the equipment acquired by the operation information acquisition unit.

[0007] In this case, the abnormal equipment identification processing unit compares the power consumption of the trunk line unit acquired by the power consumption information acquisition unit with a predetermined power consumption threshold for the corresponding trunk line, and if the acquired power consumption of the trunk line is equal to or greater than the upper limit of the corresponding threshold, it is preferable to identify the equipment identified as operational by the operational information as equipment where an abnormality has occurred.

[0008] Furthermore, it is preferable that the abnormal equipment identification processing unit compares the power consumption of the trunk line unit obtained by the power consumption information acquisition unit with a predetermined power consumption threshold for the corresponding trunk line, and identifies the equipment identified as being out of service by the operation information as equipment where an abnormality has occurred if the acquired power consumption of the trunk line is less than or equal to the lower limit of the corresponding threshold.

[0009] Preferably, the abnormal equipment identification processing unit outputs the equipment identified as having experienced an abnormality, and further obtains the power consumption measured individually for that equipment. Based on the power consumption of that equipment and the operating information, it then re-identifies the equipment where the power consumption abnormality occurred.

[0010] The abnormal equipment identification program according to the present invention is an abnormal equipment identification program that identifies equipment where an abnormality has occurred in a plurality of pieces of equipment connected to each of a plurality of trunk lines, and may cause a computer to execute a process to identify equipment where an abnormality in power consumption has occurred based on the power consumption per trunk line and the operating information of each of the plurality of pieces of equipment. [Effects of the Invention]

[0011] This invention provides a low-cost system for identifying abnormal equipment. [Brief explanation of the drawing]

[0012] [Figure 1] This is a schematic diagram showing the configuration of the equipment management system according to Embodiment 1. [Figure 2] This is a block diagram of the abnormal equipment identification device according to Embodiment 1. [Figure 3] This is a flowchart of the abnormal equipment identification system according to Embodiment 1. [Figure 4] This is a flowchart of the method for detecting power consumption anomalies in a main line according to Embodiment 1. [Figure 5] This is a flowchart illustrating the method for identifying equipment that has experienced a power consumption anomaly according to Embodiment 1. [Modes for carrying out the invention]

[0013] Embodiment 1 The following describes the equipment management system and abnormal equipment identification system according to this embodiment 1, with reference to the figures.

[0014] <Configuration of the equipment management system> First, with reference to Figure 1, the configuration of the equipment management system according to this embodiment 1 will be described. The equipment management system 100 is a system that manages multiple pieces of equipment installed in, for example, a factory, and is equipped with an abnormal equipment identification device 3.

[0015] The equipment management system 100 includes a power consumption management device 1, an operating status management device 2, an abnormal equipment identification device 3, an IoT platform 4, a main line power meter 5, an equipment power meter 6, a main line distribution board 7, a distribution board 8, a quality control board 9, a main line D, equipment power lines d, and multiple pieces of equipment E.

[0016] The power consumption management device 1 is a system that manages the power consumption of each piece of equipment E on a trunk line basis, supplying power to each piece of equipment E. The power consumption management device 1 is connected to multiple trunk line power meters 5 and an IoT platform 4. The power consumption management device 1 acquires the power consumption of trunk lines D measured by the trunk line power meters 5 at predetermined timings (typically continuously). The power consumption management device 1 then transmits the acquired power consumption of trunk lines D to the abnormal equipment identification device 3 via the IoT platform 4.

[0017] The operational status management device 2 is a system that manages the operational information of multiple pieces of equipment E. The operational status management device 2 is also called an "andon panel" and is an electronic display panel that electronically displays the operational information and work instructions of the pieces of equipment E. The operational status management device 2 is connected to multiple pieces of equipment E and the abnormal equipment identification device 3. The operational status management device 2 acquires the operational information of the pieces of equipment E at predetermined timings (typically continuously). Next, the operational status management device 2 transmits the acquired operational information of the pieces of equipment E to the abnormal equipment identification device 3. The operational information of the pieces of equipment E that is acquired includes information indicating the operational status of the piece of equipment E, such as whether the piece of equipment E is in operation, stopped, experiencing an abnormality or warning, or in emergency stop. In addition, the operational status management device 2 outputs the operational information of the pieces of equipment E from an operational information notification unit, such as a display (not shown), so that users can understand the operational information of the pieces of equipment E.

[0018] The abnormal equipment identification device 3 is a system that identifies the equipment E in which an abnormality has occurred among a plurality of pieces of equipment E connected to each of a plurality of main lines D. The abnormal equipment identification device 3 is connected to the operation status management device 2 and the IOT platform 4. The abnormal equipment identification device 3 receives from the power consumption management device 1 the power consumption information of the main line D acquired by the power consumption management device 1. Further, the abnormal equipment identification device 3 receives from the operation status management device 2 the operation information of the equipment E acquired by the operation status management device 2. Furthermore, the abnormal equipment identification device 3 also receives from the equipment power measuring device 6 the power consumption of the equipment E measured by the equipment power measuring device 6. Based on the received information, the abnormal equipment identification device 3 executes a process of identifying the main line D in which an abnormal power consumption has occurred and the equipment E in which an abnormal power consumption has occurred. The abnormal equipment identification device 3 will be described in detail later.

[0019] The IOT platform 4 is connected via a network to a plurality of IOT (Internet Of Things) devices inside and outside the factory, and receives and transmits various information. The IOT platform 4, for example, receives the power consumption of each main line D acquired by the power consumption management device 1 and transmits it to the abnormal equipment identification device 3.

[0020] The main line power measuring device 5 is connected to the main line D and the power consumption management device 1. The main line power measuring device 5 constantly measures the power consumption of the main line D and transmits the measured power consumption information to the power consumption management device 1.

[0021] The equipment power measuring device 6 is used to individually measure the power consumption of the equipment E. The equipment power measuring device 6 is not provided for each of the pieces of equipment E, but is a device held by the user to measure the power of each piece of equipment E. The equipment power measuring device 6 includes, for example, an input terminal connected to the power terminal of the equipment E, a sensor that detects the power amount based on the electrical signal input from the input terminal, a storage unit that holds the detected power amount as data, and an output unit that outputs the power amount. The user holds the equipment power measuring device 6 and moves it to appropriately measure the power consumption of the equipment E. The equipment power measuring device 6 transmits the measured power consumption of the equipment E to the abnormal equipment identification device 3 by wireless or wired communication.

[0022] The main distribution board 7 supplies power to the distribution board 8 via the main line D. Then, the distribution board 8 supplies power to the equipment E via the equipment power line d.

[0023] The quality control board 9 is a device that stores and manages product information produced by the equipment E. The product information includes, for example, identification information such as the manufacturing number of the product. The abnormal equipment identification device 3 acquires product information from the quality control board 9 via the IOT platform 4, so that when an abnormality in power consumption occurs, it becomes easy to identify the products produced by the equipment E on the main line D where the abnormality occurred.

[0024] Next, referring to FIG. 2, the configuration of the abnormal equipment identification device 3 will be described. The abnormal equipment identification device 3 includes a power consumption information acquisition unit 31, an operation information acquisition unit 32, a power consumption abnormality detection unit 33, an abnormal equipment identification processing unit 34, and a notification unit 35. The power consumption information acquisition unit 31 receives the power consumption of the main line D acquired by the power consumption management device 1 from the power consumption management device 1 via the IOT platform 4 and stores it in a storage unit (not shown). Also, the power consumption information acquisition unit 31 receives the power consumption of the equipment E acquired by the equipment power measuring instrument 6 from the equipment power measuring instrument 6 and stores it in a storage unit (not shown). The power consumption information acquisition unit 31 outputs the stored power consumption information to the notification unit 35.

[0025] The operation information acquisition unit 32 receives the operation information of the equipment E acquired by the operation status management device 2 from the operation status management device 2 and stores it in a storage unit (not shown). The operation information acquisition unit 32 outputs the stored operation information of the equipment E to the notification unit 35. The power consumption abnormality detection unit 33 detects an abnormality in power consumption based on the power consumption of the main line D stored in the power consumption information acquisition unit 31 and identifies the main line D where the power consumption abnormality occurred. The power consumption abnormality detection unit 33 outputs the information (identification information) of the identified main line D to the notification unit 35.

[0026] The abnormal equipment identification processing unit 34 primarily identifies the equipment E where the power consumption abnormality occurred, based on the power consumption of the main line D acquired by the power consumption information acquisition unit 31 from the power consumption management device 1 and the operation information of equipment E acquired by the operation status management device 2 by the operation information acquisition unit 32. Furthermore, the abnormal equipment identification processing unit 34 secondarily identifies, or re-identifies, the equipment E where the power consumption abnormality occurred, based on the power consumption of equipment E acquired from the equipment power meter 6 and the operation information of equipment E acquired from the operation information acquisition unit 32. These identification and re-identification processes will be described in detail later. The abnormal equipment identification processing unit 34 transmits the information of the identified and re-identified equipment E to the notification unit 35.

[0027] The notification unit 35 outputs information received from the power consumption information acquisition unit 31, the operation information acquisition unit 32, the power consumption abnormality detection unit 33, and the abnormal equipment identification processing unit 34 so that the user can understand it.

[0028] <How to identify abnormal equipment> The method for identifying abnormal equipment using the abnormal equipment identification device 3 according to this embodiment 1 will now be described. Figure 3 is a flowchart of the method for identifying abnormal equipment using the abnormal equipment identification device 3 according to this embodiment 1.

[0029] First, the power consumption information acquisition unit 31 receives the power consumption of the main line D from the power consumption management device 1 via the IoT platform 4 and stores it in a storage unit (not shown) (step S101). Next, the power consumption anomaly detection unit 33 detects an anomaly in the power consumption of the main line D acquired and stored by the power consumption information acquisition unit 31 and identifies the main line D where the anomaly occurred (step S102). The method for detecting power consumption anomalies will be described in detail later. Next, the operation information acquisition unit 32 receives operation information of equipment E from the operation status management device 2 and stores it in a storage unit (not shown) (step S103). Next, the anomaly equipment identification processing unit 34 identifies the equipment E where the power consumption anomaly occurred (step S104). Based on the power consumption of the main line D identified as having an anomaly in step S102 and the operation information of the equipment E connected to that main line D, the anomaly equipment identification processing unit 34 identifies the equipment E where the power consumption anomaly occurred. The method for identifying the equipment E where the power consumption anomaly occurred in step S104 will be described in detail later.

[0030] Next, after identifying the equipment E where the power consumption anomaly occurred, the user individually measures the power consumption of the identified equipment E using the equipment power meter 6. The power consumption information acquisition unit 31 receives and stores the power consumption of equipment E measured by the equipment power meter 6 (step S105). Finally, the abnormal equipment identification processing unit 34 re-identifies the equipment E where the power consumption anomaly occurred (step S106). Based on the operational information of the equipment E connected to the main line D, which was identified as having an anomaly in step S102, and the power consumption of equipment E identified as having an anomaly, which was received from the equipment power meter 6 in step S105, the abnormal equipment identification processing unit 34 re-identifies the equipment E where the power consumption anomaly occurred. In these steps, the received power consumption and operating information, as well as information on the identified and re-identified equipment E, are output to the notification unit 35 as appropriate so that the user can understand them.

[0031] If multiple pieces of equipment E are identified in step S104, it is possible that some of these pieces of equipment E may not have a problem caused by power consumption. Therefore, in step S105, the power consumption of each piece of equipment E is measured individually to re-identify the piece of equipment E whose problem is caused by power consumption. Consequently, if, for example, only one piece of equipment E is identified in step S104, and it can be definitively determined that the problem in that piece of equipment E is caused by power consumption, then re-identification is unnecessary, and steps S105 and S106 do not need to be performed.

[0032] <Method for detecting power consumption anomalies in main distribution lines> Referring to Figure 4, the method for detecting an anomaly in power consumption in the main line D using the power consumption anomaly detection unit 33 (step S102) will be described. Figure 4 is a flowchart of the method for detecting an anomaly in power consumption in the main line according to Embodiment 1.

[0033] The power consumption anomaly detection unit 33 detects an anomaly in the power consumption of the main line D based on the power consumption of the main line D stored in the power consumption information acquisition unit 31 in step S101. Specifically, the user pre-determines a power consumption threshold for the main line D, which serves as the criterion for determining abnormal power consumption, and sets it in the power consumption abnormality detection unit 33. In a typical example, this threshold includes information on the upper and lower limits of power consumption that are judged to be normal. The power consumption abnormality detection unit 33 compares the power consumption of the main line D stored in the power consumption information acquisition unit 31 with the pre-determined power consumption threshold for the corresponding main line D (step S201).

[0034] If the power consumption of the main line D stored in the power consumption information acquisition unit 31 in step S101 is above the upper limit of the threshold or below the lower limit, the power consumption anomaly detection unit 33 determines that an anomaly has occurred in the power consumption of the main line D (step S202). Then, the anomaly equipment identification device 3 executes step S103. On the other hand, if the power consumption of the main line D stored in the power consumption information acquisition unit 31 in step S101 is below the upper limit of the threshold and above the lower limit, the power consumption anomaly detection unit 33 determines that the power consumption of the main line D is normal. If the power consumption of the main line D is determined to be normal, the anomaly equipment identification device 3 does not execute step S103.

[0035] <Method for identifying equipment experiencing abnormal power consumption> Referring to Figure 5, the method (step S104) for identifying equipment experiencing a power consumption anomaly in the abnormal equipment identification processing unit 34 will be described. Figure 5 is a flowchart of the method for identifying equipment experiencing a power consumption anomaly according to Embodiment 1.

[0036] The abnormal equipment identification processing unit 34 identifies the equipment E connected to the main line D where the power consumption abnormality occurred, based on the power consumption of the main line D stored in the power consumption information acquisition unit 31 in step S101 and the operation information of the equipment E stored in the operation information acquisition unit 32 in step S103. First, the abnormal equipment identification processing unit 34 compares the power consumption of the main line D stored in the power consumption information acquisition unit 31 with a predetermined power consumption threshold for the corresponding main line D (step S401). The power consumption threshold in step S401 is the same as the power consumption threshold used in step S201. Also, step S401 is a step that takes place after it has been determined in step S202 that an abnormality has occurred in the power consumption of the main line D. Therefore, it is assumed that the acquired power consumption of the main line D is above the upper limit of the threshold, or below the lower limit.

[0037] In step S401, if the power consumption of the main line D is above the upper limit of the threshold, the abnormal equipment identification processing unit 34 extracts the operational equipment E connected to the main line D where the power consumption abnormality occurred, based on the operational information of the equipment E stored in the operational information acquisition unit 32 in step S103 (step S402). Next, similar to step S402, the abnormal equipment identification processing unit 34 extracts the equipment E connected to the main line D where the power abnormality occurred, which is experiencing an abnormality or warning, based on the operational information of the equipment E stored in the operational information acquisition unit 32 in step S103 (step S403). Next, the abnormal equipment identification processing unit 34 extracts the equipment E extracted in both steps S402 and S403 (step S404). Then, the equipment E extracted in step S404 is output to the notification unit 35 as the equipment E where the abnormality occurred. The order of steps S402 and S403 may be reversed.

[0038] On the other hand, in step S401, if the power consumption of the main line D is below the lower limit of the threshold, the abnormal equipment identification processing unit 34 extracts equipment E that is currently stopped or in emergency stop mode and connected to the main line D where the power abnormality occurred, based on the operation information of the equipment E stored in the operation information acquisition unit 32 in step S103 (step S405). Then, the abnormal equipment identification processing unit 34 outputs the equipment E extracted in step S405 to the notification unit 35 as the equipment E where the abnormality occurred.

[0039] The state of equipment E, which was identified as abnormal in steps S404 and S405, can be estimated as follows: In step S404, equipment E was identified as having a power consumption exceeding the upper threshold detected by the main line D, so it is estimated that an equipment malfunction occurred, such as a cycle time overrun. On the other hand, in step S405, equipment E was identified as having a power consumption below the lower threshold detected by the main line D, so it is estimated that a sudden emergency stop or shutdown occurred.

[0040] It should be noted that the present invention is not limited to the embodiments described above, and can be modified as appropriate without departing from the spirit of the invention.

[0041] One example of the application of this invention is carbon footprint management. To calculate the CO2 emissions per product, it is necessary to obtain the power consumption per main line and divide it by the number of products produced to calculate the power consumption per product. Therefore, when submitting the CO2 emissions per product, if there is an abnormality in the power consumption per product, it is required to explain the cause of the abnormality. With this invention, it is possible to collect information necessary to identify the cause of the abnormality in the power consumption per product, such as identifying the equipment E where the abnormality occurred and the trend of power consumption of the equipment E where the abnormality occurred.

[0042] Furthermore, this disclosure can also be implemented by having the CPU (Central Processing Unit) execute part or all of the processing of the abnormal equipment identification device 3 as an abnormal equipment identification program.

[0043] The programs described above can be stored and supplied to a computer using various types of non-transitory computer-readable media. Non-transitory computer-readable media include various types of tangible storage media. Examples of non-transitory computer-readable media include magnetic recording media, magneto-optical recording media, CD-ROMs (Read Only Memory), CD-Rs, CD-R / Ws, and semiconductor memory. Examples of magnetic recording media include flexible disks, magnetic tapes, and hard disk drives. Examples of magneto-optical recording media include optical disks. Examples of semiconductor memory include mask ROMs, PROMs (Programmable ROMs), EPROMs (Erasable PROMs), flash ROMs, and RAMs (Random Access Memory). Programs may also be supplied to a computer using various types of transient computer-readable media. Examples of transient computer-readable media include electrical signals, optical signals, and electromagnetic waves. Temporary computer-readable media can supply programs to a computer via wired communication channels such as electric wires and optical fibers, or via wireless communication channels.
