DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] At least the following points will become apparent from the description of this specification and the accompanying drawings.

[0010] =====This embodiment===== <<<Configuration of Information Processing System 10>>> 1 is a diagram showing the configuration of an information processing system 10 according to one embodiment of the present invention. The information processing system 10 is a system that, when an abnormality occurs in an inverter device 20 installed in a factory, displays information on an electronic component (hereinafter simply referred to as a "component") that caused the abnormality on a screen (described later). The information processing system 10 includes the inverter device 20, a PLC (Programmable Logic Controller) 21, an abnormality detection device 22, and an information processing device 23.

[0011] The inverter device 20 is a device for driving a load 15 such as a belt conveyor in a factory. The inverter device 20 also diagnoses whether a capacitor, which is a component included in the inverter device 20, is abnormal or not based on the operation time of various circuits included in the inverter device 20.

[0012] The PLC 21 controls predetermined equipment (not shown) in the factory based on the output from the sensor of the inverter device 20, and also diagnoses the life of parts included in the inverter device 20.

[0013] The abnormality detection device 22 is a device that detects whether or not there is an abnormality in the inverter device 20 based on the output from a sensor of the inverter device 20 .

[0014] The information processing device 23 is a device that, when the abnormality detection device 22 detects that there is an abnormality in the inverter device 20, acquires information on parts related to the abnormality of the inverter device 20 and displays it on a screen (described later). Specifically, the information processing device 23 displays the diagnosis results and the like executed by the inverter device 20 and the PLC 21 on the screen.

[0015] In this embodiment, the PLC 21 is installed in the factory similarly to the inverter device 20, the abnormality detection device 22 is installed in a server room, and the information processing device 23 is installed in a control room of the factory. Therefore, a user can remotely grasp the parts related to the abnormality of the inverter device 20 installed in the factory.

[0016] <<<Inverter device 20>>> The inverter device 20 includes a filter 30, an AC-DC conversion circuit 31, a DC-AC conversion circuit 32, a motor 33, capacitors 40 to 42, sensors 50 to 52, and a control device 53.

[0017] The filter 30 is a circuit that removes noise from the three-phase AC power supply, and includes a capacitor 40 .

[0018] The AC-DC conversion circuit 31 is a circuit that generates a predetermined DC voltage from a three-phase AC voltage from which noise has been removed, and is configured to include, for example, a capacitor 41 (first capacitor) that smoothes the AC voltage.

[0019] The DC-AC conversion circuit 32 is a circuit that generates an AC voltage for driving the motor 33 from a predetermined DC voltage, and is configured to include, for example, a capacitor 42 (second capacitor) that stabilizes the DC voltage.

[0020] Here, since capacitor 40 is provided on each of the wirings of phases A to C of the three-phase AC power supply, capacitor 40 actually includes capacitor 40a for phase A, capacitor 40b for phase B, and capacitor 40c for phase C. Capacitors 41 and 42 also include capacitors for phases A to C of the three-phase AC power supply, similar to capacitor 40. Capacitors 40 to 42 are, for example, aluminum electrolytic capacitors.

[0021] The sensors 50a to 50c are, for example, thermocouples provided to measure the temperatures of the capacitors 40a to 40c, respectively.

[0022] The sensors 51a to 51c are, for example, thermocouples provided to measure the temperatures of the capacitors 41a to 41c, respectively.

[0023] The sensors 52a to 52c are, for example, thermocouples provided to measure the temperatures of the capacitors 42a to 42c, respectively.

[0024] In order to measure the temperatures of the capacitors 40a-40c, the sensors 50a-50c are disposed near the capacitors 40a-40c on a substrate (not shown) of the inverter device 20. Similarly to the sensor 50, the sensors 51 and 52 are also disposed near the capacitors 41 and 42 so as to measure the temperatures of the capacitors 41 and 42.

[0025] <<<Configuration of control device 53>>> The control device 53 is a device that controls the inverter device 20, and includes a CPU 60, a memory 61, a storage device 62, counters 63 to 65, a display device 66, and a communication device 67, as shown in FIG.

[0026] The CPU 60 executes programs stored in the memory 61 and the storage device 62 to realize various functions in the control device 53 .

[0027] The memory 61 is, for example, a RAM (Random-Aaccess Memory) and is used as a temporary storage area for programs, data, and the like.

[0028] The storage device 62 is a non-volatile storage device that stores the programs executed by the CPU 60 and various data to be processed.

[0029] The counter 63 measures, for example, the time during which a predetermined three-phase AC power supply is applied to the filter 30, that is, the operation time of the filter 30.

[0030] The counter 64 measures, for example, the operation time (first time) of the AC-DC conversion circuit 31, and the counter 65 measures, for example, the operation time (second time) of the DC-AC conversion circuit 32. The count values ​​of the counters 63 to 65 are count values ​​C1 to C3, respectively. The counters 63 to 65 correspond to a timing circuit.

[0031] The display device 66 is, for example, a device such as a display, and the communication device 67 exchanges various types of information with the PLC 21, the abnormality detection device 22, and the information processing device .

[0032] <<<Information and functional blocks stored in the control device 53>>> 3 is a diagram showing an example of information stored in the control device 53 and functional blocks realized therein. Count values ​​100 to 102 are stored in the storage device 62. Furthermore, the CPU 60 of the control device 53 executes a program (not shown) in the storage device 62, whereby a diagnosis unit 110 and a display processing unit 111 are realized in the control device 53.

[0033] The count value 100 is a value for detecting an abnormality in the capacitor 40 of the filter 30 , and the count value 101 is a value for detecting an abnormality in the capacitor 41 of the AC-DC conversion circuit 31 .

[0034] The count value 102 is a value for detecting an abnormality in the capacitor 42 of the DC-AC conversion circuit 32 .

[0035] Generally, as the operating time of the filter 30 becomes longer, the performance of the capacitor 40 also deteriorates. Therefore, in this embodiment, the count value at which the operating time of the filter 30 reaches a predetermined time T1 (e.g., 10,000 hours) indicating a general lifespan of the capacitor 40 is set as the count value 100. Therefore, in this embodiment, when the count value C1 becomes larger than the count value 100, it is determined that the capacitor 40 provided in the filter 30 is abnormal.

[0036] The count values ​​101 and 102 are similar to the count value 100, and the count value 101 is set to a count value at which the operation time of the AC-DC conversion circuit 31 becomes a predetermined time T2 indicating a general life of the capacitor 41. The count value 102 is set to a count value at which the operation time of the DC-AC conversion circuit 32 becomes a predetermined time T3 indicating a general life of the capacitor 42. The count values ​​100 to 102 are values ​​determined corresponding to the capacitors 40 to 42. Therefore, for example, when the various parameters such as the material and capacitance of the capacitors 40 to 42 are the same, the count values ​​100 to 102 are the same.

[0037] The diagnosis unit 110 compares the count values ​​C1 to C3 of the counters 63 to 65 with the count values ​​100 to 102, and diagnoses the presence or absence of an abnormality in the capacitors 40 to 42. The display processing unit 111 displays the diagnosis result of the diagnosis unit 110 on the screen of the display device 66. The processes executed by the diagnosis unit 110 and the display processing unit 111 will be described in detail later.

[0038] <<<Diagnosis process S10>>> 4 is a flowchart showing an example of a diagnostic process executed by the control device 53. Note that, here, the count values ​​C1 to C3 are the first to third count values.

[0039] First, the diagnostic unit 110 sets a variable i to "1" in order to select the first count value C1 from among the count values ​​C1 to C3 (S20). Then, the diagnostic unit 110 acquires the count value C1, which is the first count value (S21).

[0040] Furthermore, the diagnosis unit 110 compares the acquired count value C1 with a count value 100, which is a threshold value for the first count value C1 (S22). If the count value C1 is greater than the count value 100 (S22: Yes), the diagnosis unit 110 determines that the first capacitor 40 is abnormal, and stores the count value C1 and the determination result in the storage device 62 in association with the capacitor 40 (S23).

[0041] On the other hand, if the count value C1 is smaller than the count value 100 (S22: No), the diagnosis unit 110 determines that the first capacitor 40 is normal, and stores the count value C1 and the determination result in the storage device 62 in association with the capacitor 40 (S24).

[0042] Further, the diagnosis unit 110 determines whether all of the three count values C1 to C3 have been acquired (S25). If not all of the count values C1 to C3 have been acquired (S25: No), the diagnosis unit 110 increments the variable i by "1" only (S26). Thereafter, by repeating processes S21 to S25, the variable i is incremented up to "3". As a result, all of the count values C1 to C3 are compared with the count values 100 to 102, and the determination result and the like are stored in the storage device 62 (S23 or S24).

[0043] And when all of the count values C1 to C3 have been acquired (S25: Yes), the display processing unit 111 displays the determination result on the screen of the display device 66 (S27). As a result, the user can grasp whether there is an abnormality in the capacitors 40 to 42 by checking the screen of the display device 66 in the factory.

[0044] Incidentally, although details will be described later, in the present embodiment, when the abnormality detection device 22 detects an abnormality in the inverter device 20, the diagnosis process S10 is executed and the determination result is transmitted to the information processing device 23. For this reason, the user can check the presence or absence of an abnormality in the capacitors 40 to 42 on the screen (described later) of the information processing device 23 in the control room.

[0045] <<<Details of PLC21>>> As shown in FIG. 1, the PLC21 (computing device) includes a CPU 70, a memory 71, a storage device 72, and a communication device 73. Note that the CPU 70, the memory 71, the storage device 72, and the communication device 73 are the same as the CPU 76, the memory 61, the storage device 62, and the communication device 67 of the control device 53 described above.

[0046] FIG. 5 is a diagram showing an example of information stored in the PLC21 and functional blocks to be realized. Threshold values 150 and 151 are stored in the storage device 72. Further, when the CPU 70 of the PLC21 executes a program (not shown) in the storage device 72, a diagnosis unit 160 is realized in the PLC21.

[0047] The threshold value 150 is a value for determining whether or not the capacitors 40-42 should be replaced based on the “remaining life” Lr (described later) of the capacitors 40-42 included in the inverter device 20. Here, for example, the life of the capacitors 40-42 is expressed by equation (1) based on Arrhenius' law.

[0048] Lc = La × 2((Ts - Ta) / 10) (1) Here, Ts is a reference temperature (e.g., 70°C), Ta is a measured temperature, La is a lifetime at temperature Ts, and Lc is an estimated lifetime or a lifetime consumption time. In this embodiment, Ta is a temperature measured by the sensors 50 to 52, and the measurement interval is constant (e.g., 1 minute).

[0049] Moreover, from formula (1), the "remaining life" or "remaining life" of the capacitors 40 to 42 is expressed by formula (2).

[0050] Lr = Ls - ΣLc (2) Here, Ls is, for example, a reference lifespan that serves as a reference when the capacitors 40 to 42 are used in a predetermined temperature environment, etc. In this embodiment, the "remaining lifespan" Lr is expressed as a ratio to the reference lifespan Ls.

[0051] Lr = Lr / Ls × 100 (3) Moreover, the threshold value 150 is set to a value that is 15% of the reference life Ls of each of the capacitors 40 to 42.

[0052] The threshold value 151 is a value for determining whether or not there is an abnormality in the capacitors 40 to 42, based on the "remaining life" Lr of the capacitors 40 to 42. In this embodiment, the threshold value 151 is set to a value that is 5% of the reference life Ls of each of the capacitors 40 to 42. Therefore, the threshold value 151 (second value: 5% of the reference life Ls) is a value smaller than the threshold value 150 (first value: 15% of the reference life Ls).

[0053] A diagnosing unit 160 compares a "remaining life" Lr calculated based on the outputs of the sensors 50-52 with thresholds 150, 151 to diagnose the states of the capacitors 40-42.

[0054] <<<Diagnosis process S11>>> 6 is a flowchart showing an example of the diagnostic process executed by the diagnostic unit 160. Here, the sensors 50a to 50c are the first to third sensors, the sensors 51a to 51c are the third to sixth sensors, and the sensors 52a to 52c are the seventh to ninth sensors. The capacitors 40a to 42c measured by the nine sensors 50a to 52c are the first to ninth capacitors, respectively. Furthermore, the diagnostic process S11 is executed at the same timing as the measurement interval (for example, one minute) of the sensors 50a to 52c, for example.

[0055] First, the diagnosis unit 160 sets a variable j to "1" in order to select the first sensor (S30). Then, the diagnosis unit 160 acquires the output of the sensor 50a, which is the first sensor (S31).

[0056] Diagnosis unit 160 calculates the "remaining life" Lr of the first capacitor based on the acquired output of the first sensor and equations (1) to (3), and stores the calculated value in storage device 72 (S32).

[0057] Once the "remaining life" Lr has been calculated, the diagnostic unit 160 compares the "remaining life" Lr of the first capacitor with a threshold value 151 for the first capacitor (here, 15% of the reference life Ls of the first capacitor) (S33). If the "remaining life" Lr is smaller than the threshold value 151 (S33: Yes), the diagnostic unit 160 attaches a "tag A" to the "remaining life" Lr, which is the calculation result, and stores it in the storage device 72 in association with the first capacitor (S34). Note that "tag A" is, for example, data such as "0" which indicates that the capacitor should be replaced.

[0058] On the other hand, if the “remaining life” Lr is greater than the threshold value 151 (S33: No), the diagnosis unit 160 compares the “remaining life” Lr of the first capacitor with the threshold value 150 of the first capacitor (here, 5% of the standard life Ls of the first capacitor) (S35).

[0059] Then, if the "remaining life" Lr is smaller than the threshold value 150 (S35: Yes), the diagnosis unit 160 attaches a "tag B" to the "remaining life" Lr, which is the calculation result, and stores it in the storage device 72 in association with the first capacitor (S36). Note that "tag B" is data such as "1" that indicates that the capacitor is abnormal.

[0060] On the other hand, if the "remaining life" Lr is greater than the threshold value 150 (S35: No), the diagnosis unit 160 determines whether the outputs of all the sensors have been acquired (S37). Note that, here, the outputs of all the sensors are the outputs of the first to ninth sensors 50a to 52c.

[0061] If the outputs of all the sensors have not been acquired (S37: No), the diagnosis unit 160 increments the variable j by "1" (S38). Thereafter, the processes S31 to S37 are repeated, and the variable j is incremented to "9". As a result, the "remaining life" Lr of all the capacitors and the tags A and B, if attached, are stored in the storage device 72 in association with the capacitors.

[0062] In addition, although details will be described later, in this embodiment, when the abnormality detection device 22 detects that there is an abnormality in the inverter device 20, the execution result of the process S11 is transmitted to the information processing device 23. Therefore, the user can check the remaining life Lr of the capacitors 40 to 42, etc. on the screen (described later) of the information processing device 23 in the control room.

[0063] <<<Details of the abnormality detection device 22>>> 7, the abnormality detection device 22 includes a CPU 80, a memory 81, a storage device 82, an input device 83, a display device 84, and a communication device 85. The five blocks in Fig. 7, the CPU 80, the memory 81, the storage device 82, the display device 84, and the communication device 85, are similar to the five blocks in the control device 53 described above, the CPU 60, the memory 61, the storage device 62, the display device 66, and the communication device 67.

[0064] The input device 83 is a device that accepts commands and data input by a user, and includes an input interface such as a keyboard and a touch sensor that detects a touch position on a touch panel display.

[0065] The storage device 82 also stores a model 90 used to detect an abnormality in the inverter device 20. The model 90 is a model generated, for example, by applying a multivariate statistical process control (MSPC) technique to the outputs of the nine sensors 50a to 52c when the inverter device 20 is operating normally.

[0066] Therefore, when data from the sensors 50a to 52c are input, the model 90 outputs a Q value, which is an index of multivariate diagnostic evaluation and indicates a statistical quantity. In this embodiment, the Q value for detecting an abnormality in the inverter device 20 is set to a predetermined "threshold value X." Therefore, when the Q value calculated using the data from the sensors 50a to 52c and the model 90 becomes larger than the "threshold value X," an abnormality in the inverter device 20 is detected.

[0067] 8 is a diagram showing an example of functional blocks realized in the abnormality detection device 22. A CPU 80 of the abnormality detection device 22 executes a program (not shown) in a storage device 82, whereby a detection unit 200 and a transmission unit 201 are realized in the abnormality detection device 22.

[0068] The detection unit 200 detects an abnormality in the inverter device 20 by using the outputs of the sensors 50a to 52c and the model 90. The transmission unit 201 transmits the result of the detection unit 200 to the information processing device .

[0069] <<<Abnormality detection process S12>>> 9 is a flowchart showing an example of an abnormality detection process executed by the abnormality detection device 22. First, the detection unit 200 acquires the outputs of all the nine sensors 50a to 50c (S40). Then, the detection unit 200 calculates a Q value based on the acquired sensor outputs and the model 90 (S41).

[0070] If the calculated Q value is greater than the "threshold value X" (S42: Yes), the detection unit 200 detects that the inverter device 20 is abnormal, and stores the detection result in the storage device 82 (S43).

[0071] On the other hand, if the calculated Q value is smaller than the "threshold value X" (S42: No), the detection unit 200 detects that the inverter device 20 is normal, and stores the detection result in the storage device 82 (S44). Then, the transmission unit 201 transmits the detection results in the processes S43 and S44 to the information processing device 23.

[0072] As a result, the user can know whether or not there is an abnormality in the inverter device 20 even if he or she is in the control room.

[0073] <<<Details of the information processing device 23>>> 10, the information processing device 23 includes a CPU 300, a memory 301, a storage device 302, an input device 303, a display device 304, and a communication device 305. Note that each block in FIG. 7 is similar to each block in the abnormality detection device 22 described above, and therefore detailed description thereof will be omitted here.

[0074] 11 is a diagram showing an example of functional blocks realized in the information processing device 23. When the CPU 300 of the information processing device 23 executes a program (not shown) in the storage device 302, a first acquisition unit 400, a second acquisition unit 401, and a display processing unit 402 are realized in the information processing device 23.

[0075] The first acquisition unit 400 acquires the diagnosis result of the process S11 executed by the PLC 21 when the abnormality detection device 22 detects that the inverter device 20 has an abnormality.

[0076] The second acquisition unit 401 acquires the diagnosis result of the process S10 executed by the control device 53 when the abnormality detection device 22 detects the presence of an abnormality in the inverter device 20. The display processing unit 402 displays the acquired diagnosis result on the screen of the display device 304 (described later).

[0077] <<<Display process S13>>> 12 is a flowchart showing an example of the display process executed by the information processing device 23. Here, it is assumed that the abnormality detection device 22 has detected the presence of an abnormality in the inverter device 20 before the process S13 is started.

[0078] First, the first acquisition unit 400 acquires the diagnosis result of the process S11 executed by the PLC 21 based on the detection result that there is an abnormality in the inverter device 20 (S50: first step). Also, the second acquisition unit 401 acquires the diagnosis result of the process S10 executed by the control device 53 (S51).

[0079] Then, the display processing unit 402 displays a selection image 500 on the screen 310 of the display device 304, as shown in FIG. 13, to allow the user to select whether to give priority to the display of the “remaining life” Lr or the “operating time” related to the capacitor (S52).

[0080] Here, the selection image 500 includes a comment "Please select the item you want to prioritize," an icon 501 labeled "remaining life," and an icon 502 labeled "operating time."

[0081] Then, when the "remaining life" icon 501 is tapped and selected based on the result of the user's operation (S53: remaining life), the display processing unit 402 displays a screen 510 in which the "remaining life" Lr is prioritized on the screen 310 (S54: second step). Note that the information indicating that the "remaining life" icon 501 has been tapped corresponds to the first information.

[0082] 14 is a diagram showing an example of a screen 510. The screen 510 displays the "remaining life" Lr and "operating time" for each of nine capacitors in ascending order of "remaining life" Lr based on the diagnosis results acquired in processes S50 and S51.

[0083] The top row of screen 510 shows a ninth capacitor (i.e., capacitor 42c) with a “remaining life” Lr of 3%, followed by the fifth capacitor with a “remaining life” Lr of 10%, and the first capacitor with a “remaining life” Lr of 18%.

[0084] In addition, the ninth capacitor (third part) has a "remaining life" Lr of 3%, which is less than 5% (second value), so the "Message" column displays the message "Abnormal" (third message). In addition, the ninth capacitor's "operating time" is "10050" hours, and the "Message" column displays the message "Abnormal".

[0085] In addition, on screen 510, the fifth capacitor (second part) has a “remaining life” Lr of 10%, which is less than 15% (first value), so the “Message” column displays a message (second message) urging the user to replace the capacitor, stating “Replacement recommended.”

[0086] Furthermore, when the "operation time" icon 502 is tapped and selected based on the result of the user's operation (S53: operation time), the display processing unit 402 displays a screen 511 in which the "operation time" is prioritized on the screen 310 (S55). Note that the information indicating that the "operation time" icon 502 has been tapped corresponds to the second information.

[0087] 15 is a diagram showing an example of a screen 511. The screen 511 displays the "remaining life" Lr and "operating time" for each of nine capacitors in order of the longest "operating time" based on the diagnosis results acquired in processes S50 and S51.

[0088] The top row of screen 511 shows a ninth capacitor (i.e., capacitor 42c) with an “operating time” of “10050” hours, followed by the first capacitor with an “operating time” of “9466” hours, and the fifth capacitor with an “operating time” of “9100” hours.

[0089] The ninth capacitor (first component) has an "operating time" of "10050" hours, which is longer than the predetermined 10,000 hours (predetermined time), and therefore displays a message "abnormal" (first message) in the "Message" field. Therefore, a user can obtain information about components related to the abnormality in inverter device 20 installed in a factory by checking screens 510 and 511 while in the control room.

[0090] <<<Configuration of information processing system 11>>> Fig. 16 is a diagram showing a configuration of an information processing system 11 according to an embodiment of the present invention. Fig. 17 is a diagram showing details of inverter devices 25a-25n and PLCs 26a-26n installed in factory F1. Like the information processing system 10 in Fig. 1, the information processing system 11 is a system that, when an abnormality occurs in any of a plurality of inverter devices installed in each of a plurality of factories F1-Fn, displays information on an electronic component that caused the abnormality on a screen (described later).

[0091] The information processing system 11 includes inverter devices 25a-25n and PLCs 26a-26n provided in the factories F1-Fn, respectively, an abnormality detection device 27, and an information processing device 28. Since the various devices provided in the factories F2-Fn are similar to the devices in the factory F1, the factory F1 will be mainly described here.

[0092] <<<About Inverter Device 25>>> Fig. 18 is a diagram showing an example of the configuration of an inverter device 25a. The inverter device 25a includes a filter 30, an AC-DC conversion circuit 31, a DC-AC conversion circuit 32, a motor 33, capacitors 40-42, sensors 50-52, and a control device 55. Comparing the inverter device 25a with the inverter device 20 of Fig. 1, the configurations are the same except for the control device 55. Therefore, the control device 55 will be described here.

[0093] The control device 55 is a device that controls the inverter device 25a, and as shown in Fig. 19, includes a CPU 60, a memory 61, a storage device 62, counters 63a to 63c, 64a to 64c, and 65a to 65c, a display device 66, and a communication device 67. Comparing the control device 55 with the control device 53 in Fig. 2, the two are the same except that the control device 55 includes nine counters 63a to 63c, 64a to 64c, and 65a to 65c.

[0094] The counters 63a-63c, 64a-64c, 65a-65c each measure the operation time of the capacitors 40a-40c, 41a-41c, 42a-42c by incrementing a count value. Therefore, the control device 55 can measure the operation time of each of the nine capacitors. Note that the "operation time of a capacitor" is, for example, the time during which a circuit in which the capacitor is provided operates and a voltage is applied to the capacitor.

[0095] The CPU 60 of the control device 55 executes the diagnostic process S10 shown in Fig. 4 at every period T1 (e.g., 1 ms) to diagnose whether or not there is an abnormality in the nine capacitors. Note that hereinafter, the diagnostic result when the diagnostic process S10 is executed is referred to as the "simple diagnostic result." In addition, in the simple diagnostic result, whether the capacitor is normal (hereinafter, appropriately represented as "O") is obtained based on the determination result of process S24 in Fig. 4, for example, and whether the capacitor is abnormal (hereinafter, appropriately represented as "X") is obtained based on the determination result of process S23.

[0096] Then, the communication device 67 of the control device 55 transmits various information acquired by the inverter device 25a to the abnormality detection device 27. Specifically, the communication device 67 transmits the simplified diagnosis result and the operation times of the nine capacitors of the inverter device 25a to the abnormality detection device 27 every period T1, and transmits the outputs of the nine sensors 50a to 52c to the abnormality detection device 27 every period T2 (for example, one minute). Note that the inverter devices 25b to 25n are similar to the inverter device 25a, and therefore detailed description thereof will be omitted here.

[0097] <<<PLC26について> >> The PLC 26a is a device similar to the above-mentioned PLC 21, and includes a CPU 70, a memory 71, a storage device 72, and a communication device 73, as shown in Fig. 1. The CPU 70 of the PLC 26a executes the diagnostic process S11 shown in Fig. 6 every period T3 (e.g., 1 s). Note that, hereinafter, the diagnostic result obtained when the diagnostic process S11 is executed is referred to as a "logical diagnostic result."

[0098] In addition, in the logical diagnosis result, whether the capacitor is normal ("◯"), abnormal ("X"), or in a state where replacement is recommended (hereinafter referred to as "Δ") is obtained based on the value of the remaining life Lr in FIG. 6. Specifically, whether the capacitor is normal ("◯") is obtained based on the result when the remaining life Lr of the capacitor is longer than 15% of the reference life Ls (process S35: No). Also, whether the capacitor is abnormal ("X") is obtained based on the result when the remaining life Lr of the capacitor is shorter than 5% of the reference life Ls (process S33: Yes). Furthermore, whether the capacitor is in a state where replacement is recommended ("Δ") is obtained based on the result when the remaining life Lr of the capacitor is 5% to 15% of the reference life Ls (process S35: Yes).

[0099] Then, the communication device 73 of the PCL 26a transmits the logical diagnosis result and the remaining lives Lr of the nine capacitors calculated in the diagnosis process S11 at every predetermined period T3 to the abnormality detection device 27. Note that the PLCs 26b to 27n are similar to the PLC 26a, and therefore detailed description thereof will be omitted here.

[0100] <<<About grouping devices>>> Incidentally, the period until the capacitor of the inverter device 25 installed in the factory F1 becomes abnormal varies depending on various factors such as the temperature and humidity of the installation location, the usage conditions (usage time, load), etc. However, generally, an inverter device that is used for a long time and drives a large load is more likely to become abnormal. Therefore, in this embodiment, the multiple inverter devices 25a-25n are classified into multiple groups (for example, five groups) according to the degree to which an abnormality is likely to occur, for example, based on the usage conditions, etc. Therefore, the inverter devices 25a-25n belong to one of the multiple groups.

[0101] In this embodiment, for example, the inverter devices 25a and 25b belong to group 1 which is assumed to be the most likely to cause an abnormality, and the inverter device 25n belongs to group 2 which is assumed to be the second most likely to cause an abnormality. Note that, for convenience, only the inverter devices belonging to groups 1 and 2 have been described here, but the remaining inverter devices also belong to one of the groups in the same manner.

[0102] In this way, since the multiple inverter devices 25a-25n in this embodiment belong to any of multiple groups, the inverter devices 25a-25n and PLCs 26a-26n also transmit information on the group to which they belong to the abnormality detection device 27. Specifically, when the communication device 67 of the inverter device 25a transmits the simplified diagnosis result, the operating times of the nine capacitors, and the outputs of the nine sensors 50a-52c to the abnormality detection device 27, the communication device 67 transmits the group information together with information on the group to which the inverter device 25a belongs (for example, group 1). Note that the group information in this embodiment is data including, for example, a tag for identifying the factory and a tag for identifying the group.

[0103] Furthermore, when the communication device 73 of the PLC 26a transmits the logical diagnosis result and the remaining lifespan Lr of the nine capacitors calculated in the diagnosis process S11 to the abnormality detection device 27, it also transmits group information to which the PLC 26a belongs. Since the PLC 26a is provided corresponding to the inverter device 25a, the group to which the PLC 26a belongs is the same as the group to which the inverter device 25a belongs. Similarly, the communication device 73 transmits group information to which the inverter devices 25b to 25n and PLCs 26b to 26n belong. Therefore, when an abnormality occurs in the inverter device, the user can display the status of the parts for each group on the screen, as will be described in detail later.

[0104] <<<About the Anomaly Detection Device 27>>> The abnormality detection device 27 in Figs. 16 and 17 is a cloud server that detects whether or not there is an abnormality in the inverter devices 25a to 25n based on various information transmitted from the inverter devices 25a to 25n and the PLCs 26a to 26n via a network. Note that the "cloud server" is, for example, a virtual server whose computing performance and storage capacity are adjustable. Thus, in this embodiment, the abnormality detection device 27 is a server that can acquire information from each of the factories F1 to Fn. Therefore, a user can acquire various information by accessing the abnormality detection device 27 using an information processing device 28, which is a terminal.

[0105] 7 is a diagram showing an example of a detailed configuration of the abnormality detection device 27. As with the abnormality detection device 22, the abnormality detection device 27 includes a CPU 80, a memory 81, a storage device 82, an input device 83, a display device 84, and a communication device 85. Comparing the abnormality detection device 27 with the abnormality detection device 22, the model stored in the storage device 82 and the program (not shown) executed by the CPU 80 are different. Therefore, hereinafter, a model 95 and functional blocks executed by the abnormality detection device 27 will be described.

[0106] The storage device 82 stores a model 95 used to detect an abnormality in the inverter devices 25a to 25n. The model 95 is a classifier generated using, for example, a support vector machine technique. In this embodiment, for example, the model 95 is generated by executing machine learning using normal data when the inverter device 25a is normal and abnormal data when the inverter device 25a is abnormal as learning data.

[0107] Here, the "learned data" used in this embodiment are the outputs of the nine sensors 50a-52c, the operating times of the nine capacitors, and the remaining lives Lr of the nine capacitors. As described above, the outputs of the sensors 50a-52c are data generated every period T2 (e.g., 1 minute), and the operating times of the nine capacitors are data generated every period T1 (e.g., 1 ms). The remaining lives Lr of the nine capacitors are data generated every period T3 (e.g., 1 s).

[0108] In this way, since the periods (i.e., granularity) of the three pieces of data used as learning data are different, in this embodiment, a predetermined pre-processing is performed to match the granularity between the pieces of data when generating the model 95. Here, the "pre-processing" refers to, for example, a process of thinning out the data on the operation times of the nine capacitors and the remaining life Lr so that the number of pieces of data on the operation times of the nine capacitors per unit time and the number of pieces of data on the remaining life Lr match the number of pieces of data on the sensors 50a to 52c. Note that, although the thinning process has been described as an example of the "pre-processing", this is not limiting, and for example, the moving averages of the data on the operation times of the nine capacitors and the data on the remaining life Lr may be calculated so that the granularity of the three pieces of data per unit time matches.

[0109] 20 is a diagram showing an example of functional blocks realized in abnormality detection device 27. When CPU 80 of abnormality detection device 27 executes a program (not shown) in storage device 82, an acquisition unit 210, a detection unit 211, and a communication unit 212 are realized in abnormality detection device 27.

[0110] The acquiring unit 210 acquires the outputs (temperatures) of the nine sensors 50a-52c, the operating times of the nine capacitors, and the remaining lives Lr of the nine capacitors to detect an abnormality in the inverter devices 25a-25n. In the following, in this embodiment, the outputs of the nine sensors 50a-52c, the operating times of the nine capacitors, and the remaining lives Lr of the nine capacitors are referred to as "abnormality detection data." Furthermore, the acquiring unit 210 acquires simple diagnosis results, logical diagnosis results, and group information transmitted from the inverter devices 25a-25n and the PLCs 26a-26n. The acquiring unit 210 stores the acquired various information in the storage device 82.

[0111] The detection unit 211 detects abnormalities in the inverter devices 25a-25n by using the abnormality detection data and the model 95. The communication unit 212 transmits the diagnosis result (hereinafter, abnormality diagnosis result) of the detection unit 211, the simple diagnosis result, the logical diagnosis result, and group information to the information processing device 28. The communication unit 212 may further transmit the outputs of the nine sensors 50a-52c, the operating times of the nine capacitors, and the remaining lives Lr of the nine capacitors to the information processing device 28.

[0112] <<<Abnormality detection process S15>>> 21 is a flowchart showing an example of an abnormality detection process executed by the abnormality detection device 27. First, the acquisition unit 210 acquires abnormality detection data related to the inverter device 25a, that is, the outputs (temperatures) of the nine sensors 50a to 52c, the operating times of the nine capacitors, and the remaining lives Lr of the nine capacitors (S60). Then, the detection unit 211 executes preprocessing on the abnormality detection data (S61).

[0113] Specifically, as a preprocessing, the detection unit 211 executes a process of thinning out the data on the operating times of the nine capacitors and the remaining life Lr so that the granularity of the three pieces of data for abnormality detection matches. Then, the detection unit 211 executes a process of detecting whether or not there is an abnormality in the inverter device 25a based on the preprocessed data for abnormality detection and the model 95 (S62).

[0114] If the detection unit 211 detects that there is an abnormality (S62: Yes), the detection unit 211 stores an abnormality diagnosis result indicating that the inverter device 20a is abnormal in the storage device 82 (S63). On the other hand, if the detection unit 211 detects that there is no abnormality (S62: No), the detection unit 211 stores an abnormality diagnosis result indicating that the inverter device 20a is normal in the storage device 82 (S64).

[0115] Here, the abnormality detection device 27 has been described only for the inverter device 25a among the multiple inverter devices, but the same process is performed for the other inverter devices 25b to 25n. As a result, the abnormality detection device 27 can detect the presence or absence of an abnormality in all the inverter devices 25a to 25n installed in, for example, the factory F1. Furthermore, the abnormality detection device 27 also performs the same process for the devices in the factories F2 to Fn as for the device in the factory F1. Therefore, the abnormality detection device 27 of this embodiment can detect the presence or absence of an abnormality in all the inverter devices installed in the factories F1 to Fn.

[0116] <<<Details of the information processing device 28>>> 10, the information processing device 28 includes a CPU 300, a memory 301, a storage device 302, an input device 303, a display device 304, and a communication device 305. Note that each block such as the CPU 300 has been described above, and detailed description thereof will be omitted here.

[0117] 22 is a diagram showing an example of functional blocks realized in the information processing device 28. When the CPU 300 of the information processing device 28 executes a program (not shown) in the storage device 302, an acquisition unit 410 and a display processing unit 411 are realized in the information processing device 28.

[0118] When the abnormality detection device 27 detects an abnormality in any of the inverter devices 25a to 25n, the acquisition unit 410 acquires the abnormality diagnosis result, the logical diagnosis result, the simple diagnosis result, and group information from the abnormality detection device 27. The display processing unit 402 displays the acquired abnormality diagnosis result, logical diagnosis result, and simple diagnosis result on the screen (described later) of the display device 304 of the information processing device 28 for each group of the factory.

[0119] <<<Display process S16>>> 23 is a flowchart showing an example of a display process executed by the information processing device 28. Here, it is assumed that before the process S16 is started, the abnormality detection device 27 detects an abnormality in the inverter device 25a of the factory F1, for example.

[0120] First, when the acquisition unit 410 detects that there is an abnormality in the inverter device 25a, it acquires the abnormality diagnosis results of the inverter devices 25a-25n of the factory F1 stored in the storage device 82 of the abnormality detection device 27 (S70). In addition, the acquisition unit 410 acquires the logical diagnosis results of the inverter devices 25a-25n from the storage device 82 of the abnormality detection device 27 (S71), and acquires the simplified diagnosis results of the inverter devices 25a-25n (S72).

[0121] Furthermore, the acquisition unit 410 acquires group information relating to the groups to which the inverter devices 25a to 25n belong from the storage device 82 of the abnormality detection device 27 (S73). Then, the display processing unit 402 displays a screen 550 showing the inverter diagnosis results for each group on the display device 304 (S74).

[0122] 24 is a diagram showing an example of the screen 550. The screen 550 includes, for example, an image 600 showing the diagnosis results of the inverter devices 25a and 25b belonging to group 1 in the factory F1, and an image 601 showing the diagnosis results of the inverter device 25n belonging to group 2. Note that, for convenience, only images of the diagnosis results of the inverter devices belonging to some groups are shown here, but for example, by moving a scroll portion (not shown) of the screen 550 downward, images of the diagnosis results of the inverter devices belonging to other groups can be displayed.

[0123] The diagnosis result of the "inverter device 25a" is displayed in the upper part of the image 600. Specifically, the image 600 includes information indicating a "simple diagnosis result" and a "logical diagnosis result" corresponding to the "capacitor number" of the inverter device 25a, and an "abnormality diagnosis result."

[0124] Here, the "abnormality diagnosis result" of the inverter device 25a shows "x" indicating that there is an abnormality in the inverter device 25a. At this time, the user can refer to the information in the "logical diagnosis result" and "simple diagnosis result" to identify which of the nine components (capacitors) of the inverter device 25a is most likely to have a problem.

[0125] Specifically, in image 600, the "logical diagnosis results" are displayed as follows: the first and ninth capacitors are normal (good), the second capacitor is abnormal (not good), and the third capacitor is in a state where replacement is recommended (low). Also, the "simple diagnosis results" are displayed as follows: the first and ninth capacitors are normal (good), and the second and third capacitors are abnormal (not good). Therefore, the user can understand that, for example, of the nine capacitors in inverter device 25a, there is a high possibility that a problem is occurring with the second or third capacitor.

[0126] Moreover, image 600 includes the diagnosis result of inverter device 25b, and image 601 includes the diagnosis result of inverter device 25n belonging to group 2. Therefore, when an abnormality is detected in any of the multiple inverter devices, the user can also grasp information about the capacitors of the other inverter devices that have not been diagnosed as abnormal.

[0127] In addition, the screen 550 displays the "simple diagnosis result", the "logical diagnosis result", and the "abnormality diagnosis result" as the diagnosis results of the "inverter device 25a", but is not limited to this. For example, the display processing unit 402 may display the operating time and the remaining life Lr. By displaying such information, the user can more objectively identify the part causing the abnormality.

[0128] ===Summary=== The information processing system 10 of this embodiment has been described above. When an abnormality occurs in the inverter device 20, the information processing device 23 displays the "remaining life" Lr on the screen 310 in association with a plurality of capacitors, as shown in, for example, a screen 510. This allows the user to know which capacitors need to be replaced or the like.

[0129] Also, for example, "lifetime consumed" Lc may be used instead of "remaining lifespan" Lr. However, by displaying "remaining lifespan" Lr on the screen 510 or the like, the user can more easily grasp the remaining lifespan.

[0130] Furthermore, in addition to the “remaining life” Lr, the screen 510 also displays the “operating time” in association with the capacitor. Therefore, the user can obtain more information regarding the abnormality of the inverter device 20.

[0131] Moreover, on screen 510, information is displayed in ascending order of "remaining life" Lr, and on screen 511, information is displayed in descending order of "operating time." Therefore, the user can organize and grasp the status of different items related to abnormalities in the inverter device 20.

[0132] Furthermore, on screens 510 and 511, the message "Abnormal" is displayed for capacitors whose "operating time" is longer than 10,000 hours. This allows the user to easily identify the capacitors related to the abnormality.

[0133] Furthermore, on screens 510 and 511, a message stating "replacement recommended" is displayed for capacitors whose "remaining life" Lr is less than 15%, allowing the user to easily identify the capacitors related to the abnormality.

[0134] Furthermore, on screens 510 and 511, the message "Abnormal" is displayed for capacitors whose "remaining life" Lr is less than 5%. This allows the user to easily identify the capacitors related to the abnormality.

[0135] Furthermore, in this embodiment, an abnormality is detected in the inverter device 20, but it may be detected in other devices such as a general DC power supply device or a power amplifier.

[0136] Furthermore, when an abnormality occurs in any of the inverter devices 25a to 25n, the acquisition unit 410 of the information processing device 28 of this embodiment acquires a logical diagnosis result (information regarding the life of the capacitor), and the display processing unit 411 displays the logical diagnosis result on the screen 550. Therefore, when an abnormality occurs in the inverter device, the user can identify the part causing the abnormality.

[0137] Furthermore, in generating the model 95, the abnormality detection device 27 of the present embodiment uses three pieces of data as learning data, namely, the outputs of the nine sensors 50a to 52c, the operating times of the nine capacitors, and the remaining lifespan Lr of the nine capacitors, but is not limited to this. Any two pieces of data out of the three pieces of data may be used as learning data. Specifically, for example, the outputs of the nine sensors 50a to 52c and the remaining lifespan Lr of the nine capacitors may be used as learning data.

[0138] Furthermore, since the anomaly detection device 27 of this embodiment uses the above-mentioned three pieces of data as learning data when generating the model 95, it is possible to generate a model 95 with high anomaly detection accuracy.

[0139] Furthermore, the display processing unit 411 displays the logical diagnosis results of the inverter devices 25a to 25n for each group on the screen 550. Therefore, the user can accurately grasp the status of inverter devices that have the same degree of possibility of abnormality occurring, for example.

[0140] Furthermore, the display processing unit 411 also displays the simplified diagnosis results (information related to operation time) of the inverter devices 25a to 25n for each group on the screen 550. This allows the user to more accurately grasp the part causing the abnormality in the inverter device.

[0141] Furthermore, the abnormality detection device 27 is a server connected to a plurality of factories F1 to Fn via a network. Therefore, a user can easily obtain various information by accessing the abnormality detection device 27 using an information processing device 28, which is a terminal.

[0142] The above-mentioned embodiment is for the purpose of facilitating understanding of the present invention, and is not intended to limit the present invention. Furthermore, the present invention can be modified or improved without departing from the spirit of the present invention, and it goes without saying that the present invention includes equivalents thereof.

[0143] For example, in this embodiment, the sensors 50-52 are configured to measure the temperatures of the capacitors 40-42, which are electrolytic capacitors, but other types of capacitors may be used. Also, the measurement target is not limited to a capacitor, and may be other electronic components such as a coil or resistor. Even when the sensors 50-52 measure the temperatures of these electronic components, the same effects as in this embodiment can be obtained.

[0144] For example, the model 90 is generated using the MSPC method, but is not limited to this. For example, a model may be generated by learning a neural network by machine learning using normal data and abnormal data from the sensors 50a to 52c as teacher data.

[0145] Furthermore, the abnormality detection device 22 may detect an abnormality in the inverter device 20 by, for example, calculating a Mahalanobis distance for normal data from the sensors 50a to 50c or using a One Class SVM technique.

[0146] In addition, in this embodiment, the abnormality detection device 22 and the information processing device 23 are separate devices, but this is not limited to this. For example, the information processing device 23 may be a device that includes all the functions of the abnormality detection device 22. In such a case, it is not necessary to provide the abnormality detection device 22 separately. [Explanation of symbols]
