Abstract
Description
Technical Field
[0001] The present invention relates to a technology for remotely and automatically performing general routine maintenance inspections of electrical equipment installed in electrical facilities such as substations.
Background Art
[0002] Regarding the maintenance inspection of electrical equipment such as substations, conventionally, a maintenance inspector goes to the site where the electrical equipment is installed, and observes the state of the equipment according to the inspection items.
[0003] As inspection items, (1) reading of meters installed in electrical equipment / confirmation of numerical values and status values displayed on monitors, (2) observation of the appearance such as dirt and damage of the equipment, (3) observation of abnormal noises emitted from the equipment, (4) confirmation of the presence or absence of abnormal odors in the equipment, etc. are used.
[0004] Regarding the reading of meters, as shown in Patent Document 1, a method of reading the memory of an analog meter by processing an image taken by a camera has been proposed. Also, regarding the confirmation of numerical values and status values displayed on monitors, as shown in Non-Patent Documents 1 and 2, a system for reading the state of electrical equipment via a network has been proposed.
[0005] Regarding the observation of the appearance, as shown in Non-Patent Document 3, attempts have been made to monitor the appearance of equipment using surveillance cameras. That is, in addition to cost reduction due to labor saving and labor shortage due to the declining birthrate, the labor saving of substation patrols has been demanded more than ever. Therefore, as a means to replace visual patrols, the use of drones, patrol robots, and a large number of cameras has been considered.
[0006] However, drones have concerns about falling due to narrow spaces or electromagnetic field effects, and substation patrol robots are costly. Therefore, in Non-Patent Document 3, a substation monitoring system using a plurality of cameras is constructed to investigate the possibility of replacing visual patrols.
[0007] Regarding the observation of abnormal noises, as shown in Non-Patent Document 4, a method has been proposed to detect device abnormalities by analyzing the sounds collected with a microphone. Also, regarding the confirmation of abnormal odors, as shown in Non-Patent Documents 5 and 6, devices for performing odor analysis have been proposed by taking samples back to the laboratory. Furthermore, as shown in the fire alarm of Non-Patent Document 7, various gas sensors have been proposed.

Embodiments for Carrying Out the Invention
[0017] Hereinafter, an electrical equipment remote comprehensive inspection system (electrical equipment remote comprehensive inspection method) according to an embodiment of the present invention will be described. According to this system, it is possible to automatically perform all aspects of daily maintenance inspections of electrical equipment such as those installed in electrical facilities such as substations remotely.
[0018] That is, it automatically measures all items such as the values and status values of meters and monitors for inspection items, visual inspection of appearance, observation of abnormal sounds, and confirmation of abnormal odors, enabling all aspects of daily inspections to be carried out without the maintenance inspector having to go to the site. In particular, for the confirmation of abnormal odors that could not be achieved by conventional methods, a composite sensing system has been constructed to achieve highly reliable confirmation of abnormal odors.
Examples
[0019] Based on FIGS. 1 to 38, Example 1 of the above system will be described. In FIG. 1, 1 indicates the above system.
[0020] The system 1 includes a group of information and communication terminals 4, a group of meter reading devices 5, a group of fixed monitoring camera devices 6, a group of mobile monitoring camera devices 7, a group of acoustic collection devices 8, a group of olfactory sensor devices 9, a group of indoor environment measurement devices 10, a group of outdoor environment measurement devices 11, an on-site inspection server 12, and a remote monitoring terminal 13.
[0021] Here, since each of the devices 4 to 11 is used for remotely inspecting the electrical equipment in the substation, it can be called an inspection device. Also, each of the devices 4 to 11 is prepared according to the number of electrical equipment 10 and control panels 20 (hereinafter referred to as inspection target equipment) to be inspected, and is installed for each inspection target equipment.
[0022] ≪Arrangement status≫ In electrical facilities such as substations, as shown in FIGS. 13 and 14, electrical equipment 30 such as transformers and circuit breakers are arranged side by side, and control panels 20 for controlling these electrical equipment 30 are arranged side by side in the electrical room. The maintenance inspection work performed by conventional maintenance inspectors involves walking around inside the electrical facility to inspect the electrical equipment 30, control panels 20, etc.
[0023] In contrast, in this embodiment, each of the devices 4 to 12 is arranged at various locations inside the electrical facility to remotely monitor the state of the inspection target equipment. The remote monitoring terminal is arranged in the maintenance management room at a remote location.
[0024] (1) Inside the electrical room Based on FIG. 13, an arrangement example of each of the devices 4, 6, 8 to 10, 12 in the electrical room will be described (the devices 5, 7, 11 are not arranged inside the electrical room).
[0025] 20-1, 20-2, 20-3... 20-N in FIG. 13 indicate the control panels 20 arranged inside the electrical room. The information and communication terminal 4 is arranged inside each of these control panels 20. Also, the acoustic collection device 8, the olfactory sensor device 9, and the indoor environment device 10 are arranged so as to surround the periphery of each of the control panels 20-1, 20-2, 20-3... 20-N.
[0026] A fixed surveillance camera 6 is arranged so as to surround each of these devices 8 to 10 (the devices 5, 7, and 11 are not arranged in the electrical room.). In addition, a on-site inspection server 12 is arranged at a predetermined location in the electrical room.
[0027] (2) Outdoor Based on FIG. 14, an arrangement example of each of the devices 4 to 11 outdoors in an electrical facility will be described. 30-1, 30-2, 30-3... 30-N in FIG. 14 indicate electrical equipment 30 installed outdoors. In addition, 30-2 indicates electrical equipment 30 where a meter without communication means such as a mechanical meter is installed, and a meter reading device 5 is arranged.
[0028] An acoustic collection device 8, an olfactory sensor device 9, and an outdoor environment device 11 are arranged so as to surround each of these electrical facilities 30-1, 30-2, 30-3... 30-N. A mobile surveillance camera 11 is arranged so as to surround each of these devices 8, 9, and 11, and a fixed surveillance camera device 6 is arranged so as to surround the device 11.
[0029] ≪Configuration of Each Device 4 to 13≫ (1) Information communication device 4 For each information communication device 4, a general-purpose data collection / transmission terminal of Non-Patent Document 1 or a multifunctional digital relay of Non-Patent Document 2 can be used, and it is installed on various control panels 20 in the electrical room of a substation in the same manner as in Documents 1 and 2.
[0030] Here, for each information communication device 4, control parameters are input from the on-site inspection server 12, and measurement values by built-in sensors of the electrical equipment 30 and state values such as "ON" / "OFF" of the electrical equipment 30 that gather at the control panel 20 are collected and acquired according to the input control parameters.
[0031] In addition, for smart meters and the like among the meters installed in the electrical equipment 30 whose meter pointer values can be collected by communication means, the meter pointer values are collected as measurement values by the information communication terminal 4. Each information communication device 4 transmits the measurement values and state values acquired according to the input control parameters to the on-site inspection server 12.
[0032] (2) Meter reading device 5 Among the meters installed in the electrical equipment 30, for those mechanical meters such as the oil level gauge of the transformer that do not have communication means, the information communication device 4 cannot collect the meter pointer value. Therefore, as described above, the meter reading device 5 is installed in the electrical equipment 30-2 to collect the meter pointer value.
[0033] Specifically, as shown in FIG. 2, each meter reading device 5 has a camera 5a, a lighting 5b, and a meter reading terminal 5c. Analytical parameters and control parameters are input to the meter reading terminal 5c from the on-site inspection server 12. By outputting a lighting control signal according to this control parameter, the lighting 5b is turned on / off. Here, when the lighting 5b is turned on, the meter is photographed by the camera 5a, and the photographed image is input to the meter reading terminal 5c.
[0034] In addition, the meter reading terminal 5c analyzes the photographed image by the same method as in Patent Document 1 according to the input analytical parameters, and reads the meter pointer value. The meter pointer value and the photographed image read here are transmitted to the on-site inspection server 12 according to the input control parameters.
[0035] At this time, the photographed image input from the camera 5a is temporarily stored (stored) in a storage area (not shown) prepared in the meter reading terminal 5c. However, if the storage capacity of the said area | region is reached, the old photographed image will be deleted sequentially, and a new photographed image will be stored.
[0036] (3) Fixed monitoring camera 6 As shown in FIG. 3, each fixed monitoring camera device 6 has a visible light camera 6a, an infrared camera 6b, a lighting 6c, a camera pan-tilt 6d, and a fixed image shooting terminal 6e. This fixed image shooting terminal 6e photographs the appearance of the inspection target facilities 20 and 30 according to the control parameters input from the on-site inspection server 12, and transmits the photographed image to the on-site inspection server 12.
[0037] That is, the fixed image capturing terminal 6e controls the operation of the pan-tilt 6d by outputting a pan-tilt operation signal to adjust the imaging directions of the two cameras 6a and 6b, and further outputs an illumination control signal to turn on / off the illumination 6c.
[0038] Here, the illumination 6c is preferably visible light LED illumination with low power consumption. When the illumination 6c is turned on, the two cameras 6a and 6b capture the appearance of the electrical equipment 30 and the control panel 20. At this time, the visible light captured by the visible light camera 6a and the infrared image captured by the infrared camera 6b are respectively input to the fixed image capturing terminal 6e and transmitted to the on-site inspection server 12.
[0039] (4) Mobile surveillance camera 7 As shown in FIG. 4, each mobile surveillance camera 7 includes a visible light camera 7a, an infrared camera 7b, an illumination 7c, a camera pan-tilt 7d, a mobile camera trolley 7e, and a mobile image capturing terminal 7f. A mobile camera trolley controller 7h is built into the trolley 7e.
[0040] The mobile image capturing terminal 7f captures the appearance of the electrical equipment 30 according to the control parameters input from the on-site inspection server 12 and transmits the captured image to the on-site inspection server 12. That is, the mobile image capturing terminal 7f outputs a trolley operation signal to the controller 7h to control the operation of the trolley 7e. Here, the trolley 7e is configured as a monorail type mobile trolley and is movable within the installation range of the rail 7g with the various devices 7a to 7d mounted thereon.
[0041] In addition, the mobile image capturing terminal 7f controls the operation of the pan-tilt 7d by outputting a pan-tilt operation signal to adjust the imaging directions of the two cameras 7a and 7b, and outputs an illumination control signal to turn on / off the illumination 7c. Here, the illumination 7c is preferably visible light LED illumination with low power consumption, similar to the illumination 6c. When the illumination 7c is turned on, the two cameras 7a and 7b capture the appearance of the electrical equipment 30.
[0042] At this time, the visible light image captured by the visible light camera 7a and the infrared image captured by the infrared camera 6b are respectively input into the mobile image capturing terminal 7f and transmitted to the on-site inspection server 12.
[0043] (5) Acoustic collection device 8 As shown in FIG. 5, each acoustic collection device 8 has a microphone 8a and an acoustic collection terminal 8b. Control parameters and analysis parameters are input into this acoustic collection terminal 8b from the on-site management server 3.
[0044] Acoustic signals around the equipment 20 and 30 to be inspected collected by the microphone 8a are input into the acoustic collection terminal 8b. At this time, the acoustic collection terminal 8b analyzes the input acoustic signals by the method of Non-Patent Document 4 according to the input analysis parameters, and acquires the presence or absence of abnormal sounds and the abnormal sound level as abnormal sound data.
[0045] In addition, the acoustic collection terminal 8b transmits the abnormal sound data and the acoustic signals to the on-site management server 3 according to the input control parameters. Note that the acoustic signals input from the microphone 8a are temporarily stored in a storage area (not shown) prepared in the acoustic collection terminal 8b, and when the storage capacity of this area is reached, the old acoustic signals are sequentially deleted and new acoustic signals are stored.
[0046] (6) Olfactory sensor device 9 As shown in FIG. 6, the olfactory sensor device 9 has a pair of "NaOH" filters 9a, activated carbon filters 9b, solenoid valves 9A and 9B, an olfactory sensor 9c, a pump 9d, a device control unit 9e, and a data analysis unit 9f. The "NaOH" filter 9a is a filter for removing corrosive gases contained in the air, and the activated carbon filter 9b is a filter for removing abnormal odor components contained in the air.
[0047] The electromagnetic valves 9A and 9B adjust the valve opening / closing degree according to the input of valve adjustment commands (valve opening / closing degrees A and B) from the device control unit 9e. The olfactory sensor 9c outputs a sensor signal corresponding to the inhaled gas, and an artificial olfactory system constituted by a sensor array equipped with a plurality of sensors such as those in Patent Document 2 and Non-Patent Document 8 is used.
[0048] The pump 9d sucks in the gas and circulates the gas within the olfactory sensor device 9. The pump 9d used in this embodiment is attached with a flow meter, and can control the flow rate of the gas circulating within the olfactory sensor device 9 based on the device control command of the gas flow rate.
[0049] The device control unit 9e receives the control parameters input from the local management server 3, and controls the electromagnetic valves 9A and 9B, the pump 9d, and the data analysis unit 9f based on the pre-set control information.
[0050] The data analysis unit 9f records the analysis parameters input from the local management server 12, and records the control parameters, the sensor signal recording command, and the data analysis command input from the device control unit 9e. Here, the olfactory signal input from the olfactory sensor 9c is recorded as time-series sensor signal data according to the sensor recording command. Also, in response to the data analysis command, data analysis is performed to diagnose the presence or absence of abnormal odor around the facilities 20 and 30 to be inspected.
[0051] To explain the details of the operation of the olfactory sensor device 9, the pump 9d is controlled to inhale the gas inside. At this time, by controlling the opening / closing degrees of the electromagnetic valves 9A and 9B, the gas passing through both filters 9a and 9b and the gas passing only through the "NaOH" filter 9a without passing through the activated carbon filter 9b are alternately inhaled.
[0052] Here, the abnormal odor components of the inhaled gas are detected by the olfactory sensor 9c, and the detected abnormal odor components are output to the data analysis unit 9f. The data analysis unit 9f sets the analysis control state value as follows according to the sensor signal recording command and the data analysis command (however, the recording command is set with priority). (A) The values of both instructions "0" are set to the "standby state value". (B) The value of the sensor signal recording instruction "1" is set to the "recording state value" of the sensor signal data. Since the sensor signal recording instruction is set with priority, in the case of the value "1" of both instructions, it is set to the "recording state value". (C) The value of the sensor signal recording instruction "0" AND the value of the data analysis instruction "1" are set to the "data analysis state value".
[0053] When the set analysis control state value is the "recording state value", the sensor signal data obtained by arranging the sensor signals input from the olfactory sensor 6c in time series as described above is recorded. On the other hand, in the case of the "analysis state value", the control parameter and the sensor signal data are extracted, and the feature amount data of the sensor signal data is created.
[0054] That is, first, the average value of the sensor signals during the sample OFF time (valve opening / closing degrees A, B = "0") is calculated, and the difference value of the sensor signal data is discretely calculated from the calculated average value and arranged to create the feature amount data for each sensor. An example of creating this feature amount data is shown in FIG. 7.
[0055] Next, it is arranged into high-dimensional vector data composed of the calculated feature amount data. This high-dimensional vector data becomes the feature amount data. An example of arranging it into a high-dimensional vector to obtain the feature amount data is shown in FIG. 8.
[0056] Thereafter, the data analysis unit 9f uses the analysis parameter and the feature amount data for a support vector machine (SVM), not shown, to diagnose the presence or absence of an abnormal odor. The diagnosis result of "abnormal odor present" or "abnormal odor absent" obtained by this diagnosis is transmitted as abnormal odor data to the on-site inspection server 12. In this embodiment, the presence or absence of an oil odor and a burnt odor is diagnosed as the abnormal odor.
[0057] The support vector machine is a two-class classifier to which analysis parameters are applied. That is, the analysis parameters include parameters of the linear input elements of the two-class classifier obtained by offline learning using, as teacher data, feature amounts based on sensor signal data of odor components with and without odors collected in advance. For example, the presence or absence of an odor can be diagnosed by threshold determination from the teacher data.
[0058] (7) Indoor environment device 10 As shown in FIG. 9, the indoor environment measurement device 10 includes a thermometer 10a, a hygrometer 10b, a CO gas sensor (carbon monoxide gas sensor) 10c, and an indoor environment measurement terminal 10d. Control parameters are input to this indoor environment measurement terminal 10d from the on-site inspection server 12.
[0059] In addition, temperature information from the thermometer 10a, humidity information from the hygrometer 10b, and information on the CO gas sensor intensity (concentration of carbon monoxide gas) from the sensor 10c are respectively input to the indoor environment measurement terminal 10d. The information group input here is organized as indoor environment information around the control panel 20 in the electric room according to the control parameters and transmitted to the on-site inspection server 12.
[0060] (8) Outdoor environment measurement device 11 As shown in FIG. 10, the outdoor environment measurement device 11 includes a thermometer 11a, a hygrometer 11b, a CO gas sensor 11c, an anemometer 11d, and an outdoor environment measurement terminal 11e. Control parameters are input to this outdoor environment measurement terminal 11e from the on-site inspection server 12.
[0061] In addition, temperature information from the thermometer 11a, humidity information from the hygrometer 11b, information on the CO gas sensor intensity from the sensor 11c, and information on the wind direction and wind speed from the anemometer 11d are respectively input to the outdoor environment measurement terminal 11e. The information group input here is organized as outdoor environment information around the electrical equipment 30 according to the control parameters and transmitted to the on-site inspection server 12.
[0062] (9) On-site inspection server 12 The on-site inspection server 11 is composed of a server arranged in the electrical room. As shown in FIG. 11, it downloads the control parameters and analysis parameters created offline and stores them in a built-in storage device (not shown).
[0063] While transmitting the control parameters and analysis parameters stored here to each of the devices 4 to 11, it receives the transmission information of each of the devices 4 to 11 and performs data arrangement and storage. Also, it provides an inspection screen to the remote monitoring terminal 12, receives the inspection screen input data of the remote monitoring terminal 12 for the inspection screen, and arranges and stores the input values of the received data.
[0064] (10) Remote monitoring terminal 13 As shown in FIG. 12, the remote monitoring terminal displays the inspection screen provided by the on-site inspection server 12 via the network. The maintenance inspector viewing this inspection screen can perform various inputs on the inspection screen and transmit the inspection screen input data to the on-site inspection server 12 via the network. In addition, the inspection report arranged on the inspection screen can also be output to a file, printer, etc.

[0109] S81, S82: The device control unit 9c checks whether an olfactory inspection command has been received at the start of operation (S81). As a result of this check, if the olfactory inspection command has not been received, the device is stopped (S82) and the process ends.
[0110] S83~S87: As a result of the check in S81, if the olfactory inspection command has been received, the device control unit 9e outputs valve opening / closing degrees A and B to the solenoid valves 9A and 9B according to the olfactory sensor operation parameters, outputs control parameters to the pump 9d, sucks gas inside, and causes the olfactory sensor 9c to measure an olfactory sensor signal (S83).
[0111] The olfactory sensor signal measured here is output to the data analysis unit 9f, and the data analysis unit 9f analyzes the olfactory sensor signal according to the olfactory sensor parameters (S84). At this time, the data analysis unit 9f determines the presence or absence of an oil smell and the presence or absence of a burnt smell in parallel (S84a, S84b).
[0112] The analysis result is sorted as abnormal odor data around the equipment 20 and 30 to be inspected (S85), and the sorted abnormal odor data is transmitted to the on-site inspection server 12 (S86). After that, if the next abnormal odor inspection command has not been received (S87), the process proceeds to S82 to stop the device and end the process.
[0113] (7) Indoor environment measurement device 10 Based on FIG. 23, an operation example of the indoor environment device 10 will be described.
[0114] S91, S92: The indoor environment device 10 checks whether it has received an indoor environment measurement command at the start of operation (S91). If, as a result of this check, it has not received an indoor environment measurement command, the device is stopped (S92) and the process ends.
[0115] S93 - S96: If, as a result of the check in S91, it has received an indoor environment measurement command, the thermometer 10a, the hygrometer 10b, and the CO gas sensor 10c measure the temperature, humidity, and CO gas intensity around the control panel 20 (S93).
[0116] Each piece of information measured here is organized as indoor environment data (S94), and the organized indoor environment data is transmitted to the on - site inspection server 12 (S95). After that, if it has not received the next indoor environment measurement command (S96), it proceeds to S92, stops the device, and ends the process.
[0117] (8) Outdoor environment measurement device 11 Based on FIG. 24, an operation example of the outdoor environment measurement device 11 will be described.
[0118] S101, S102: The outdoor environment device 11 checks whether it has received an outdoor environment measurement command at the start of operation (S101). If, as a result of this check, it has not received an outdoor environment measurement command, the device is stopped (S102) and the process ends.
[0119] S103 - S106: If, as a result of the check in S101, it has received an outdoor environment measurement command, the thermometer 11a, the hygrometer 11b, the CO gas sensor 11c, and the anemometer 11d measure the temperature, humidity, CO gas intensity, wind speed, and wind direction around the electrical equipment 30 (S103).
[0120] Each piece of information measured here is organized as outdoor environment data (S104), and the organized outdoor environment data is transmitted to the on - site inspection server 12 (S105). After that, if it has not received the next outdoor environment measurement command (S106), it proceeds to S102, stops the device, and ends the process.
[0121] (9) On - site inspection server 12 Based on FIG. 25, an operation example of the on-site inspection server 12 will be described.
[0122] After starting the operation, the on-site inspection server 12 operates the processes of the inspection function units (various setting function unit 40, inspection schedule management function unit 50, data collection / recording function unit 60, comprehensive analysis function unit 70, inspection report creation function unit 80) in parallel (S111).
[0123] If the operation processes of all these function units 40 to 80 are completed, the device is stopped and the operation is terminated (S112). On the other hand, if not all are completed, the processes of the function units 40 to 80 are continued.
[0124] Note that the remote monitoring terminal 13 can access the on-site inspection server 12 via the network and remotely use the various setting function unit 40 of the on-site inspection server 12.
[0125] ≪Details of the inspection function units 40 to 80≫ (1) Various setting function unit 40 Based on FIG. 26, the details of the various setting function unit 40 will be described. Here, the various setting function unit 40 causes a Web browser to display an inspection setting screen 90 that can be accessed and operated from the on-site inspection server 12 / remote monitoring terminal 13. That is, when a maintenance inspector selects the inspection setting screen 90 on the Web browser (S120), the corresponding inspection setting screen 90 is called (S121).
[0126] In this embodiment, as the inspection setting screen 90, various screens such as a control parameter setting screen 90a, an analysis parameter setting screen 90b, an inspection schedule management screen 90c, an inspection data browsing screen 90d, and an inspection report creation screen 90e are prepared.
[0127] Then, a user such as a maintenance inspector performs operations such as browsing and setting input on each inspection screen 90a to 90e (S122). After the browsing / operation is completed and the screen of the inspection setting screen 90 is closed (S123), the operation process of the various setting function unit 40 is terminated.
[0128] (2) Inspection Schedule Management Function Unit 50 The inspection schedule management function unit 50 constantly monitors the inspection schedules of each inspection device 4 to 11. If the operation process is described based on Fig. 27, at the start of the operation, it is confirmed whether the time of the clock 91 of the current inspection server 12 is the inspection time (S131). If it is not the inspection time, the process directly proceeds to S132.
[0129] On the other hand, if it is the inspection time, the command values of each command of the control parameter information terminal transmission command, meter reading command, fixed camera shooting command, mobile camera shooting command, acoustic collection command, abnormal odor inspection command, indoor environment measurement command, and outdoor environment measurement command are set to "Yes" and activated, and each control parameter is transmitted to each inspection device 4 to 11, and the process proceeds to S132.
[0130] In S132, it is confirmed whether the inspection stop is commanded from the remote monitoring terminal 13. If it is not commanded, it waits until the next inspection time. On the other hand, if it is commanded, the operation process ends.
[0131] (3) Data Collection and Recording Function Unit 60 The data collection and recording function unit 60 sorts out each inspection data received from each inspection device 4 to 11 and stores it in the inspection record database. That is, as shown in Fig. 28, the data collection and recording function unit 60 confirms the reception of inspection data at the start of the operation (S141). If it has not received the inspection data, the process directly proceeds to S142.
[0132] On the other hand, if it has received the inspection data, the received inspection data is sorted out (S143), the sorted inspection data is stored in the inspection record database (S144), and the process proceeds to S142. In S142, it is confirmed whether the inspection stop is commanded from the remote monitoring terminal 13. If it is not commanded, the process returns to S141 to continue the operation process. On the other hand, if it is commanded, the operation process ends.
[0133] The configuration of the inspection database will be described below with reference to Fig. 29. This inspection database records each inspection data for each inspection date and time, and is composed of a data series that combines information on inspection devices 4 to 11, inspection target facilities 20 and 30, observation location labels, inspection data, inspection data status, and confirmation status into one unit.
[0134] The column for the inspection device records the classification of the information communication terminal 4, meter reading device 5, fixed monitoring camera device 6, mobile monitoring camera device 7, acoustic collection device 8, olfactory sensor device 9, indoor environment measurement device 10, outdoor environment measurement device 11, and on-site inspection server 12 that perform measurement and analysis of inspection data. In Fig. 29, one of each group of inspection devices 4 to 11 is exemplified as 4-1 to 11-1.
[0135] The column for the inspection target facility records the classification of the electrical equipment 30 and the control panel 20. In Fig. 29, the control panel 20-1 and the electrical equipment 30-1 are exemplified. At this time, for the acoustic collection device 8, olfactory sensor device 9, indoor environment measurement device 10, and outdoor environment measurement device 11, the indoor / outdoor classification is recorded. Note that the on-site inspection server is left blank.
[0136] The column for the observation location label records the measurement value names such as current value and voltage value for the information communication terminal. For the meter reading device 5, fixed monitoring camera device 6, and mobile monitoring camera device 7, the observation locations such as the oil level gauge, the upper part of the transformer, and the left part of the circuit breaker are recorded. Furthermore, for the acoustic collection device 8, olfactory sensor device 9, indoor environment measurement device 10, and outdoor environment measurement device 11, the installation locations of each inspection device 8 to 10 such as one location indoors or one location outdoors are recorded. Note that for the on-site inspection server 12, the types of comprehensive analysis such as abnormal sound distribution estimation and abnormal odor distribution estimation described later are recorded.
[0137] The column for the inspection data records the inspection data (measurement values, meter pointer values, etc.) received from each inspection device 4 to 11. The column for the inspection data status records the inspection data status values of undetermined, normal, and abnormal for the status of the inspection data. However, when the on-site inspection server 12 operates the data collection and recording function unit 60, the undetermined value shall be set for the inspection data status value.
[0138] In the confirmation status column, the maintenance staff records the confirmation status value indicating whether the inspection data has been confirmed or not. However, when the on-site inspection server 12 operates the data collection and recording function unit 60, the unconfirmed status shall be set as the confirmation status value.
[0139] (4) Comprehensive analysis function unit 70 The comprehensive analysis function unit 70 operates after the on-site inspection server 12 operates the data collection and recording function unit 60. Based on FIG. 30, when the operation process of the comprehensive analysis function unit 70 starts, the operation processes of inspection data threshold judgment (S151), inspection data status judgment (S152), abnormal sound distribution estimation (S153), and abnormal odor distribution estimation (S154) are executed in sequence.
[0140] After that, it is confirmed whether the inspection stop has been commanded from the remote monitoring terminal 13. If not, the operation processes of S151 to S154 are repeated. On the other hand, if it has been commanded, the operation process ends. Hereinafter, the details of the operation processes of S151 to S154 will be described.
[0141] S151: In the inspection data threshold judgment, it is confirmed whether the measured value (inspection data) collected by the information communication terminal 4 falls within the allowable range between the preset upper limit value and the lower limit value. As a result of the confirmation, if it falls within the allowable range, the inspection data status of the inspection data is set to normal. Otherwise, the inspection data status is set to abnormal.
[0142] Also, it is confirmed whether the meter pointer value (inspection data) collected by the meter reading device 5 falls within the allowable range between the preset upper limit value and the lower limit value. As a result of the confirmation, if it falls within the allowable range, the inspection data status value of the inspection data is set to normal. Otherwise, the inspection data status is set to abnormal. At this time, for the inspection data status value of the photographed image of the meter associated with the meter pointer value, the inspection data status value is set in the same manner as the meter pointer value.
[0143] Furthermore, check the infrared images (inspection data) collected by the fixed monitoring camera device 6. If there is a location where the temperature is equal to or higher than the preset maximum temperature, it is determined that there is abnormal heating, and the inspection data status value of the inspection data is set to abnormal. On the other hand, if not, the inspection data status value is set to normal.
[0144] Similarly, check the infrared images (inspection data) collected by the mobile monitoring camera device 7. If there is a location where the temperature is equal to or higher than the preset maximum temperature, it is determined that there is abnormal heating, and the inspection data status value of the inspection data is set to abnormal. On the other hand, if not, the inspection data status value is set to normal.
[0145] S152: In the inspection data status determination, first, compare the status values (inspection data) such as "ON" / "OFF" collected by the information communication terminal 4 with the operation status values with correct status values during the operation of the electrical equipment 30. As a result of the comparison, if it is correct, the inspection data is set to normal. On the other hand, if not, the inspection data status value is set to abnormal.
[0146] Next, when there is abnormal sound data (inspection data) in the abnormal sound collection device 8, the inspection data status value of the inspection data is set to abnormal. On the other hand, if not, the inspection data status value is set to normal.
[0147] However, for the abnormal sound data set to abnormal, check whether the abnormal sound level falls within the allowable range between the preset upper limit value and the lower limit value. As a result of the check, if it falls within the allowable range, the inspection data status value of the inspection data is updated to normal. On the other hand, if not, the inspection data status remains set to abnormal.
[0148] Also, if there is "oil smell" in the abnormal odor data (inspection data) of the odor sensor device 9, the inspection data status of the inspection data is set to abnormal. On the other hand, if not, the inspection data status is set to normal. Similarly, if there is "burn smell" in the abnormal odor data (inspection data), the inspection data is set to abnormal. On the other hand, if not, the inspection data status is set to normal.
[0149] S153: Explain the processing content of abnormal noise distribution estimation (S153) based on Fig. 31. First, plot the installation locations of the acoustic collection devices 8 on the layout diagram of the electrical equipment 30 after the start of the operation process (S161). Next, draw a circle with a size corresponding to the abnormal noise level of the abnormal noise data centered on the plotted installation locations (S162) to create an abnormal noise distribution estimation diagram. The circles in this abnormal noise distribution estimation diagram are called abnormal noise estimation circles.
[0150] After that, list the electrical equipment near the abnormal noise estimation circles as the equipment requiring attention for abnormal noise generation (S163). Here, organize the list of equipment requiring attention for abnormal noise generation and the abnormal noise distribution estimation diagram as the abnormal noise distribution estimation result, and save it to the inspection record database (S164).
[0151] Fig. 32 shows an example of the abnormal noise distribution estimation diagram, where the electrical equipment 30-1 and the electrical equipment 30-2 are described in the list of equipment requiring attention for abnormal noise generation. Thus, if there is abnormal noise somewhere around the inspection target equipment 20 and 30, set the inspection data status value of these inspection data to abnormal; otherwise, set the inspection status value to normal (S165), and end the operation process.
[0152] S154: Explain the abnormal odor distribution estimation (S154) based on Fig. 33. First, plot the installation locations of the olfactory sensor devices 9 on the layout diagram of the electrical equipment 30 after the start of the operation process (S171). Next, indoors (in the electrical room), draw a circle with a pre-determined indoor abnormal odor size centered on the installation locations (S172) to create an abnormal odor distribution estimation diagram.
[0153] On the other hand, outdoors, obtain the outdoor abnormal odor estimation center according to the wind speed and wind direction measured by the outdoor environmental measurement device 11 at the same installation position as the plotted olfactory sensor device 9 (see Fig. 14) (S173). Based on this outdoor abnormal odor estimation center, draw a circle with a pre-determined outdoor abnormal odor size (S174) to create an abnormal odor distribution estimation diagram.
[0154] The circles in the malodor distribution estimation diagram (S172, S174) created here are called malodor estimation circles. When creating the malodor distribution estimation diagram, the malodor estimation circles due to oil odor and the malodor estimation circles due to burnt odor are represented in different colors based on the malodor data.
[0155] Also, when the CO gas sensor intensity of the outdoor environment measurement device 11 / indoor environment measurement device 10 (see FIGS. 13 and 14) at the same installation location as the plotted olfactory sensor device 9 is greater than the preset allowable CO gas sensor intensity, the malodor estimation circle is represented in a different color. Furthermore, when abnormalities are found in both the burnt odor and the CO gas sensor intensity, the malodor estimation circle is represented in an even different color.
[0156] At this time, if there is any heating in the structures of the electrical equipment 30 or the control panel 20, the olfactory sensor device 9 will react, and when the structure becomes even hotter and approaches combustion, CO gas will be generated. Therefore, by coordinating the outputs of the olfactory sensor device 9 and the CO gas sensor 10c, it is expected to enhance the detection accuracy of abnormal heating occurring in the electrical equipment 30 or the control panel 20.
[0157] After that, the electrical equipment near the malodor estimation circle is listed as malodor generation caution equipment (S175). FIG. 34 shows an example of the malodor distribution estimation diagram. Outdoor, the electrical equipment 30-1 and 30-2 are described in the malodor generation caution equipment list, while indoors (in the electrical room), the control panels 20-1 and 20-2 are described in the same list.
[0158] Here, the malodor generation caution equipment list and the malodor distribution estimation diagram listed are organized as malodor distribution estimation results and saved in the inspection record database (S176). In this way, if there is malodor somewhere around the equipment 20 and 30 to be inspected, the inspection data status value of these inspection data is set to abnormal, otherwise the inspection status value is set to normal (S177), and the operation process ends.
[0159] (5) Inspection Result Report Creation Functional Unit 80 Based on FIG. 35, the operation process of the inspection report creation function unit 80 will be described. When the operation process is started, the inspection report creation function unit 80 reads out each inspection data of the specified inspection date and time from the inspection record database (S181), arranges it in the inspection report, and outputs it as a file (S182, S183). For example, if the output destination of the inspection report is set to a printer, the inspection report is output to the printer and printed on paper, and the process ends.
[0160] ≪Daily Inspection Example≫ The daily inspection example of the inspection target facilities 20 and 30 according to this embodiment will be described. On the inspection schedule management screen 90c of the remote monitoring terminal 13, the interval of the inspection time is set in advance, such as 2 hours, and the inspection time is automatically registered in the inspection schedule at the set inspection time interval. Here, as an example, the inspection schedule up to one month later is automatically registered.
[0161] The inspection schedule is not limited to the above-mentioned automatic registration, and it is also possible to manually add, change, or delete the inspection time. The collection of each inspection data for the inspection target facilities 20 and 30 is carried out by the automatic operation of each inspection device 4 to 11 according to the inspection schedule.
[0162] (1) During daily inspection, the maintenance inspector accesses the on-site inspection server 12 via the network using the remote monitoring terminal 13, and remotely uses the various setting function units 40 of the on-site inspection server 12 to view the inspection schedule management screen 90c.
[0163] On the inspection schedule management screen 90c, as shown in Fig. 36(a), a monthly schedule is displayed. For each date of this monthly schedule, each inspection work status of "Inspected", "Confirmed", "Inspection Reserved", and "Abnormal" is displayed. During this display, "Inspected" indicates a state where inspection data has been collected at all inspection times of the date, "Confirmed" indicates a state where a maintenance inspector has confirmed some inspection data at the inspection time of this day after it has been inspected, "Inspection Reserved" indicates a state where the inspection time is registered but the inspection data has not been collected, and "Abnormal" indicates a state where the inspection data could not be collected at some point during the inspection time of the date due to reasons such as a failure of inspection devices 4 to 11.
[0164] When the date of the monthly schedule is specified, as shown in Fig. 36(b), a daily schedule is displayed. In this daily schedule, each inspection work status of "Inspected", "Confirmed", "Inspection Reserved", and "Abnormal" is displayed for each inspection time.
[0165] (2) For daily inspection work, the maintenance inspector designates the inspected time of the daily schedule, and operates the inspection data viewing and confirmation screen 90d to confirm the inspection data of each inspection device 4 to 11. At this time, on the inspection data viewing and confirmation screen 90d, as shown in Fig. 37, the inspection data for the designated inspection date and time is read from the inspection record database, sorted, and displayed.
[0166] In the inspection record database, for each of the inspection devices 4 to 11, the following items are displayed: (a) equipment to be inspected 20, 30, (b) observation location label, (c) reference information, (d) inspection data, (e) inspection data status, and (f) confirmation status. Here, the equipment to be inspected indicates the control panel 20 and electrical equipment 30, and the observation location label indicates the observation locations (current value, voltage value, oil level gauge, observation location, outdoor location, indoor location) of the preset equipment to be inspected 20, 30.
[0167] As reference information, for example, upper and lower limit values for measured values of inspection data, operation state values for inspection data state values, past information of visible light images and infrared images (such as shooting results one month ago), past information of environmental measurement values such as temperature, humidity, CO gas sensor intensity, wind speed, and wind direction (such as measurement results one month ago), etc. are displayed.
[0168] Also, the inspection data state value indicates the state value output as a result of the comprehensive analysis of each inspection data by the comprehensive analysis function unit 70 of the on-site inspection server 12. Furthermore, the confirmation state indicates the confirmation state of inspection data and the like by the maintenance inspector.
[0169] Regarding inspection data composed of data series such as visible light images, infrared images, acoustic signals (graphs), abnormal sound distribution estimation diagrams, abnormal sound generation attention equipment lists, abnormal odor distribution estimation diagrams, and abnormal odor generation attention equipment lists among such items, a reduced image is displayed on the inspection data browsing and confirmation screen 90d. Also, if each of the above items is selected from the inspection data browsing and confirmation screen 90d, as shown in FIG. 38, a detailed inspection data browsing and confirmation screen 90f for only the selected item is displayed.
[0170] (3) The maintenance inspector browses the inspection data browsing and confirmation screen 90d and the detailed inspection data browsing and confirmation screen 90f to confirm the validity of the inspection data state values of each item, and if the confirmation is completed, sets the confirmation state of the corresponding item to confirmed.
[0171] At this time, for those for which inspection data state values are not set by the comprehensive analysis function unit 70 of the on-site inspection server 12, such as images (visible light images, infrared images), temperature, humidity, CO gas sensor intensity, wind speed, and wind direction, the maintenance inspector views each inspection data to judge the inspection data state and sets the inspection data state value.
[0172] Also, even if it is an inspection data state value that has been set by the comprehensive analysis function unit 70 of the on-site inspection server 12, it can be changed according to the judgment of the maintenance inspector. Furthermore, the maintenance inspector shall enter the feelings obtained from the inspection data confirmation work in the remarks column.
[0173] When the maintenance inspector sets the confirmation status for all items and closes the inspection data viewing and confirmation screen 90d, the inspection work status at the corresponding time of the daily schedule is set to "Confirmed". As a result, the inspection work status for the corresponding date of the monthly schedule is also set to "Confirmed".
[0174] Regarding the display items of the inspection data viewing and confirmation screen 90d at the inspection date and time that has become "Confirmed", they can be output as an inspection report by the inspection result report creation functional unit 80. The maintenance inspector designates the inspection date and time to be output as needed and outputs the inspection report to a file or printer.
[0175] Therefore, according to this embodiment, the entire routine inspection work including the confirmation of abnormal odors that has conventionally relied on human senses is automatically measured, and it becomes possible to perform maintenance inspection work remotely without the maintenance inspector going to the site.
[0176] At this time, by the maintenance inspector considering the abnormal odor data of the odor sensor device 9 and the photographed images of the visible light cameras 6a, 7a (confirmation of oil leakage), it is possible to achieve a highly reliable confirmation of oil odor. Also, by the maintenance inspector considering the abnormal odor data of the odor sensor device 9, the CO gas sensor intensity, and the infrared images of the infrared cameras 6b, 7b (confirmation of abnormal heating), it is also possible to achieve a highly reliable confirmation of burnt odor.
Embodiment
[0177] Based on FIGS. 39 to 43, Embodiment 2 of the system 1 will be described. Here, odor level detection is added to the system 1.
[0178] In Embodiment 1, the data analysis unit 9f of the odor sensor device 9 determines the presence or absence of oil odor and the presence or absence of burnt odor in parallel during the analysis of the odor sensor signal. Regarding this point, the data analysis unit 9f of this embodiment further performs parallel detection of the oil odor level and the burnt odor level during the analysis of the odor sensor signal.
[0179] Specifically, as shown in FIG. 39, oil odor level detection (S200a) and burnt odor level detection (200b) are added to the olfactory sensor signal analysis (S84) of the data analysis unit 9f.
[0180] (2) Oil odor level detection Based on FIG. 40, the oil odor level detection (S200a) will be described. In this oil odor level detection, the oil odor level is obtained according to the concentration amount of the oil odor gas. Here, three learning samples with different concentration amounts (oil odor levels 1 to 3) are prepared in advance as learning samples of the oil odor, and the support vector machine is learned for each concentration amount, and the olfactory sensor analysis parameters are created in advance.
[0181] When the oil odor level detection is started, the olfactory sensor signal measured in S83 is supplied to the detectors 500 by the support vector machines of oil odor levels 1 to 3 respectively, so that each detector 500 operates in parallel, and it is confirmed whether all the detectors 500 output "no oil odor" (S201).
[0182] As a result of the confirmation, if all the detectors 500 output "no oil odor", the oil odor level is set to "0" (S202). On the other hand, when any one of the detectors 500 outputs "there is oil odor", the level of the detector 500 with the highest probability value, which is the output of the detector 500, is set as the oil odor level (S203). At this time, among the detectors 500 that output "there is oil odor", it may be set to the oil odor level of the detector 500 with the highest concentration amount.
[0183] Thereafter, it proceeds to the determination of the presence or absence of oil odor in S84a. In S84a, if the "oil odor level" in S202 is "0", it is determined as "no oil odor", while otherwise it is determined as "there is oil odor".
[0184] (3) Burnt odor level detection Based on FIG. 41, the details of the burnt smell level detection (S200b) will be described. In this burnt smell level detection, the burnt smell level is determined according to the concentration amount of the burnt smell gas. Here, three learning samples with different concentration amounts (burnt smell levels 1 to 3) are prepared as learning samples of the burnt smell, and a support vector machine is learned for each concentration amount, and the olfactory sensor analysis parameters are created in advance.
[0185] When the burnt smell level detection is started, the olfactory sensor signal measured in S83 is supplied to the detector 600 by each support vector machine of the burnt smell levels 1 to 3, so that each detector 600 operates in parallel, and it is confirmed whether all the detectors 600 output "no burnt smell" (S301).
[0186] As a result of the confirmation, if all the detectors 600 output "no burnt smell", the burnt smell level is set to "0" (S302). On the other hand, when any of the detectors 600 outputs "burnt smell present", the level of the detector 600 with the highest probability value among the outputs of the detectors 600 is set as the abnormal smell level (S303). At this time, among the detectors 600 that output "burnt smell present", it may be set to the burnt smell level of the detector 600 with the highest concentration amount.
[0187] Thereafter, it proceeds to the determination of the presence or absence of burnt smell in S84b. In S84b, if the burnt smell level in S302 is "0", it is determined that there is "no burnt smell", while otherwise it is determined that there is "burnt smell".
[0188] (3) Abnormal sound distribution estimation As shown in FIG. 42, the abnormal smell distribution estimation performed by the on-site inspection server 12 of this embodiment, in addition to the abnormal smell distribution estimation of the first embodiment, displays the oil smell level / burnt smell level in characters in the abnormal smell estimation circle (S400). FIG. 43 shows an abnormal smell distribution estimation diagram according to this embodiment. "Level 2" is displayed in the abnormal smell estimation circle outdoors, while "Level 1" is displayed in the abnormal smell estimation circle indoors (electrical room).
[0189] According to this embodiment, in addition to the effects of Embodiment 1, information on the oil odor level and the burnt odor level is added, so that the understanding of maintenance inspectors regarding the state of abnormal odor generation at the site can be improved. Further, since quantitative records can be left regarding the abnormal odor, the accumulated inspection records can be effectively utilized.
Embodiment
[0190] Based on FIGS. 44 to 46, Embodiment 2 of the system 1 will be described. Here, as shown in FIG. 44, the processing of the inspection data time series analysis function unit 95 is added to the on-site inspection server 12 of the system 1.
[0191] That is, the inspection data time series analysis function unit 95 creates and displays an inspection data time series graph in which each inspection data of the measured value and state value collected by the information communication terminal 4, the meter pointer value collected by the meter reading device 5, the indoor environment data collected by the indoor environment measuring device 10, and the outdoor environment data collected by the outdoor environment measuring device 11 are plotted in time series.
[0192] Explaining based on FIG. 45, the processing of the inspection data time series analysis function unit 95 is started by selecting inspection data (measured value and state value, meter pointer value, indoor environment data, outdoor environment data) on the inspection data browsing and confirmation screen 90d.
[0193] At the start of the processing, it is confirmed whether there is a specification of the graph display period of the inspection data time series graph (S501). As a result of the confirmation, if there is a specification, the graph display period is set to the specified period (S502), while if there is no specification, the graph display period is set to the past one month (S503).
[0194] Thereafter, the inspection data (measured value and state value, meter pointer value, indoor environment data, outdoor environment data) for the graph display period of S502 and S503 is read from the inspection record database (S503), a time series data graph is created (S504), and it is displayed on the detailed inspection data browsing screen 105 shown in FIG. 46 (S505), and the processing is terminated.
[0195] At this time, assume that the period to be displayed on the time-series graph can be set and changed on the detailed inspection data viewing screen 105. According to such an embodiment, in addition to the effects of Embodiments 1 and 2, the maintenance inspector can easily confirm the time-series change in the state of the electrical equipment 30 by viewing the time-series data graph.
