Description

  The present invention is widely used in the fields of electric power, industry, and transportation, and has a function to operate a main circuit for receiving and transforming, and is installed in a plurality of business establishments such as indoor switchboards and outdoor stand-alone panels that require periodic inspection. The present invention relates to a distribution board inspection system for a distribution board.

  In plant factories and the like, a large number of switchboards containing various types of equipment are installed and operating at various locations within the business site. Some of these equipments are remotely monitored via the switchboard, and some are not remotely monitored. Even if the equipment is remotely monitored, inspectors regularly check the switchboard of each equipment. When an abnormality occurs in the equipment, switchboard, etc., maintenance work is performed to check the switchboard on site.

  In the conventional switchboard inspection, the operation state was confirmed by inspecting the meters and indicator lights, and there were many parts that depended on the judgment of abnormality contents and the repair judgment based on the experience and knowledge of the inspector.

  For example, when an abnormality is indicated by an alarm lighting or a monitor lamp, a primary diagnosis is performed and an abnormal part is specified at the discretion of an inspector.

  Periodic inspection is a useful means to detect system abnormalities at an early stage and prevent the occurrence of similar abnormalities in advance, but the results of periodic inspections are often compiled into a paper-based checklist. For this reason, it has been insufficient to use the past inspection data for the occurrence of an abnormality or the identification of a failure part.

  In addition, the devices monitored and inspected by the inspector are assigned identification numbers for determining where each device is installed, such as the OO unit, but the device number is assigned to the equipment. There was a problem that data recording errors occurred due to some not being displayed, misreading of the display, incorrect entry at the time of inspection or monitoring data recording.

Patent Document 1 discloses a maintenance work support system that can support the work of a practitioner (inspector) at a maintenance work site, which is image information and inquiry information of a maintenance target device photographed at the maintenance site. Is transmitted to the maintenance work support computer, and the maintenance support computer transmits data necessary for maintenance work support from the parts drawing database or the inspection record database to the computer at the maintenance work site. However, it is merely a manual means for instructing the replacement procedure of the failed part, and does not provide support for identifying the failed part.

The inspection server stores image recognition means, database means for managing each of the switchboards with unique identification information for information processing, position information received from the inspection terminal, and database means. The distribution board to which the image information received by collating the identification information of the unique distribution board is received is specified, and the image authentication is determined from the image information. Means for extracting and interpreting the blinking state of the light emitting element of the switchboard, and comparing the interpretation result with the relationship between the blinking state of the light emitting element previously stored as history data in the database means and the operating state corresponding to the switchboard When checking and determining that there is an abnormality, even if the cause of the abnormality cannot be uniquely identified from the blinking state, the cause of the abnormality of the switchboard is determined by the statistical method from the history data, or the failure part determination result, or the failure part It is a switchboard inspection system provided with the control means which performs the control which produces | generates the information regarding the candidate of this, and transmits to the said terminal for an inspection.

  It is possible to provide a switchboard inspection system that can easily identify a faulty part even if an inexperienced device is used.

  FIG. 1 is a functional block diagram showing a configuration of a switchboard inspection system according to an embodiment of the present invention.

  In FIG. 1, the switchboard inspection system is a device carried by an inspector, for example, an inspection terminal 1 including an electronic camera 12, a GPS receiver 11, and a data communication means 14, and the inspection terminal 1 and data. The inspection server 3 that transmits and receives and performs information processing related to support of maintenance and inspection by the database means 31 and the network 2 that transmits signals transmitted and received between the inspection terminal 1 and the inspection server 3 are provided. Check the operating state of 4n (n is a natural number, however, items common to each switchboard will be abbreviated as switchboard 4 unless otherwise described).

  FIG. 2 is an external view showing an example of the panel display of the switchboard 4.

  The switchboard 4 includes a self-test circuit, a monitor circuit, and the like (not shown), and performs a predetermined self-inspection. In FIG. 2, a simple display such as LED (here, lamps L1 to L9) display, simple meter m, or numeric an display (not shown) is performed on the panel (front surface) of the switchboard 4.

  In other words, the faulty part of the board or unit to be controlled and monitored by the switchboard 4 is not specified, and further detailed operation data and details of the fault alarm are not displayed. The integrated data is displayed with a lamp or the like. In addition, a measurement terminal (here, TP1) may be provided for an inspector to connect a predetermined measuring instrument and measure a measured value as necessary.

  Moreover, the identification mark N which can identify each switchboard 41-4n with a barcode, a number, etc. is attached to the panel of the switchboard 4 (if necessary, the front of each unit). This is to read the identification information which is one of the switchboards 41 to 4n by image recognition described later. As a result, even if GPS radio waves cannot be received, or each switchboard 4 cannot be specified by only the position information of the GPS receiver because a plurality of switchboards are installed adjacent to each other, the switchboards 4 are automatically set for each one. It is provided so that it can be identified.

  In the past, experienced operators have often identified the faulty parts of the switchboard 4 by data displayed on these panels based on experience and intuition, and the maintenance and inspection of operators with low proficiency. In the emergency inspection, there are problems such as troublesome operation or erroneous measurement.

  The inspection terminal 1 includes a transmission / reception GPS receiver 11 and an electronic camera 12 connected to each other by connection means such as an internal bus and an I / O interface, an input / output means 13 such as a display and a keyboard, and data communication means. 14 or a personal information terminal such as a handy terminal, or a mobile phone terminal having a GPS receiver 11 and an electronic camera 12 (photographing means), an input / output means 13 and a data communication means 14. Is.

  The network 2 performs signal transmission between the mobile body of the inspection terminal 1 and the inspection server 3 functioning as an information processing system placed in the center or the like, for example, like a packet communication network by data communication of a cellular phone system. It is a communication network.

  The inspection server 3 includes communication means 33 that communicates with the inspection terminal 1 via the network 2, and the inspection data and repair processing records relating to each distribution board 4 and the devices accommodated in each distribution board 4. The database means 31 stored and managed in the internal storage means, the data read from the database means 31 and the data received from the inspection terminal 1 are compared and collated, the statistical processing by the database means 31 is performed, the failure determination result, Control means for performing control to output information such as the repair method to the inspection terminal via the communication means 33, for example, the CPU (Central Control Unit) 32, the image information received from the inspection terminal 1, the blinking state of each lamp, etc. An image recognition means 34 for recognizing and extracting, and an input / output means 35 for inputting / outputting and displaying data necessary for monitoring and inspection are provided.

  The image recognition means 34 not only extracts the blinking state of the lamp from the image information, but also determines whether the object to be imaged is one of the switchboards 41 to 4n by a method such as reading the barcode of the substrate identification mark or character recognition. It can be read.

  The components of the inspection server 3 are connected by an internal bus or the like and exchange signals between the components, and the CPU 32 monitors and controls the operation of each component by monitoring the internal bus and the like.

  In the database means 31 of the inspection server 3, the position information of each switchboard 41 to 4n and the identification information of each switchboard 4 are stored in advance as a database in a storage device (not shown). When dispatching an inspector, when the identification information of the monitoring switchboard 4 input from the input / output means 35 is input, the inspection guide information is superimposed on the map information stored in the database means 31. To the terminal 1 for inspection.

  In addition, the state of each device and equipment at the time of measurement of the past switchboard 4 is edited in the table T1 as an inspection history and stored in the storage device of the database means 31, and the blinking state of the lamps of each switchboard 41 to 4n and Corresponding device operations can be retrieved by the database means 31.

  In other words, the storage device of the database means 31 of the inspection server 3 stores the position of each switchboard 41 to 4n and the operation status, failure history, and repair status of all the switchboards corresponding to the display of each switchboard 41 to 4n. The history is stored in a database as a maintenance history.

  For example, the database means 31 can design information and past information so that it can be searched which component (board, unit) is faulty when which lamp on the front panel of which switchboard 41 to 4n is lit. Measurement data is input and information related to inspection and maintenance of the switchboard 4 is statistically managed.

  For example, when the monitor lamp 1A indicating a unit failure is turned on, each unit failure history of each of the switchboards 41 to 4n is stored, and when the unit # 2 is faulty in the switchboard 4 as a whole (for example, the unit # 1 has 30 cases and # 2 has 50 cases), but on the switchboard 41, unit # 1 has 7 failures, # 2 has 4 cases and # 1 has more cases, and it is an inspection and repair method. Information such as the number of times the unit 1 has been replaced three times and a switch reset four times is entered.

  Further, failure modes are classified and stored according to combinations of lamp lighting, and repair means corresponding to each failure mode is also stored in the database means 31.

  3 and 4 are flowcharts showing the operation procedure of the switchboard inspection system.

  In addition to periodic inspections, there are cases in which an inspector rushes to the site to check the switchboard in addition to periodic inspections. Here, the switchboard 4 as a whole has a basic knowledge of device operation and operation procedures. The operation will be described by way of an example of an emergency inspection performed by an inspector who is not familiar with the operation history such as repairs and operation faults of each device.

  1 is notified to the inspection server 3 from the switchboard 41 of FIG. 1, and the inspector on duty brings the inspection terminal 1 to the operation inspection of the corresponding device.

  An alarm to be inspected from a remote monitoring system (not shown) is automatically input to the inspection server 3 via the communication means 33 together with the distribution panel identification information (distribution panel number, etc.) “41”, or the inspection server 3 It is input from the center operator through the input / output means 35 and the like, and the CPU 32 starts control of inspection operation state monitoring (step S1).

  The inspection server 3 that has received the alarm from the switchboard 4 transmits to the inspection terminal 1 a check notification for checking the switchboard 41 that has received the alarm. At this time, the operator of the inspection server 3 displays a guide to the switchboard 41 to the inspector in the input / output means 35 together with a map on the display of the inspection terminal 1, and the current position acquired by the GPS receiver 11 is displayed. As a command to be displayed, for example, “GUIDE # 41” is input (step S2).

  The CPU 32 transmits map information indicating the position of the switchboard 41 from the database unit 31 to the inspection terminal 1 via the communication unit 33. On the basis of this information, the inspection terminal 1 displays on the display a map of the installation location of the switchboard 41 and the current position based on the positional information from the GPS receiver 11 (step S3), and the inspector provides guidance. Originally arrives at the place where the switchboard 41 is installed.

  The inspector who arrives at the switchboard 41 takes an image of the inspection point, specifically, the front panel of the switchboard 41 by the electronic camera (imaging means) 12 of the inspection terminal 1 (step S4). The identification mark of the switchboard and the lighting state of the lamp are acquired as image information. The GPS receiver 11 acquires the time and position information (latitude and longitude) of this photographing timing, and transmits the information together with the image information as inspection information to the inspection server 3 via the network 2 (step S5). .

  In addition, the inspection information includes necessary data input by the operator from the input / output means 13 together with the image information and the like, and is transmitted to the inspection server 3. This data includes, for example, lamp lighting numbers, switchboard numbers, and if necessary meter values.

  The inspection server 3 that has received the inspection information from the inspection terminal 1 via the network 2 and the communication means 33 reads out the positional information (for example, NOO ° XX minutes YY seconds) acquired by the GPS receiver among the received information. Then, the position information of the identification information (number “41”) of the switchboard 41 stored in the database means 31 is collated and confirmed (step S6).

  The CPU 32 of the inspection server 3 confirms whether the identification information and 41 to be inspected coincide with NOO ° XX minutes YY seconds (step S7). If not (No in step S7), since an incorrect switchboard, for example, “44” is checked, a warning for checking the switchboard 41 correctly is notified to the inspection terminal 1 via the network 2 (step S7-1). .

  The warning is displayed as an alarm on the display of the input / output means 13 to the operator, re-photographed with the correct switchboard 41, and inspection data is transmitted (step S4).

  If they match (Yes in Step S7), the switchboard number based on the identification information extracted from the GPS position information and the switchboard number input by the inspector are further matched and matched (Yes in Step S8). From the transmitted image information, the measurement data is extracted by image recognition, and the data is organized into a table T2 in a format registered in a predetermined database (step S9).

  FIG. 5 is a flowchart showing a procedure for confirming selection of adjacent switchboards in step S7.

  Further, for example, when the switchboard 41 and the switchboard 42 are installed next to each other, two switchboards 41 and 42 at the same latitude and longitude positions are detected from the position information acquired by the GPS receiver 11. It is read from the database means 31 as a candidate to be specified as an inspection target (Yes in step S7a).

  In that case, the CPU 32 further reads and interprets the mark of the switchboard 41 read by image recognition of the received captured image (step S7b), and the switchboard 4 currently being inspected by the inspector is the switchboard 41 based on the identification information “41”. It is classified, and it is identified and confirmed whether the GPS position information and the position information of the switchboard 41 match (step S7c).

  Returning to FIG. 3 and FIG. 4 again. If the identification information and the switchboard number input by the inspector do not match (No in step S8), the CPU 32 confirms that the wrong switchboard 4 is being inspected via the network. An alarm is output through the output means 13 to notify the operator that the identification information of the switchboard 41 is an incorrect input, prompt the correction of the switchboard number, and the incorrect input is corrected by the inspector (step S8-1). ).

  Further, the CPU 32 edits the inspection data including the data inputted by the received operator into a table T2 that can be collated with T1, and checks whether or not the data in both tables match with a predetermined accuracy (step S9). If so (Yes in step S10), the data is newly written and recorded in the table T2 of the database means 31 (step S11).

  This confirmation is valid for meter reading. For example, when the lamp L2 is lit, the meter numerical value is stored in the database with the normal value “5” and “3 or less” when abnormal. However, when the meter reading data from the inspector is “4” (No in step S10), the CPU 32 generates a message for prompting the inspector to perform re-measurement and transmits the message to the inspection terminal 1. Then, remeasurement data is transmitted from the inspection terminal 1 (steps S10-1 and S10-2). Then, in response to whether or not the received remeasurement data is within the allowable range, it is written and recorded in the table T2 of the database means 31 as an additional history as new normal or abnormal data (step S11). )

  Note that data input may be omitted only by an inspector, and data may be acquired only from an image captured by the electronic camera 12. According to the above method, data can be input easily, and erroneous entry or measurement can be prevented from being lost due to measurement.

  When the production of the table T2 is completed, the CPU 32 immediately starts collation between the table T1 and the table T2 (step S12). As a database, when which lamp of which unit has failed, the history of which unit has failed in the past is recorded in the table T1, so if it is compared with the current lamp lighting state, the failure mode and The inspection / repair method can be searched and extracted. This failure mode is edited and stored in association with the table T1 as the table T3 of the database means 31.

  FIG. 6 is a database table T3 in which correspondence between lamp lighting and failure modes is arranged.

  In FIG. 6, for example, when the lamp L1 and the lamp L3 are lit simultaneously, it is classified as failure mode A, and unit # 1 is reset as a repair method candidate A-1.

  Subsequently, the CPU 32 reads out the past inspection result data, that is, the table T3 from the newly acquired data table T2 and the database means 31, compares them, and performs probabilistic statistical processing by a preset program. Then, as described above, for example, from the lighting state of the lamp in each switchboard 4, the faulty part that needs the most trouble or repair in the switchboard 41 is determined, or a candidate of a part that is likely to fail Is prepared (step S13).

  The CPU 32 first searches for data for determining the failure part from the history data stored in the table T1 of the database means 31 in addition to the determination of the failure part based on the combination of the lighting state of the lamp. Data necessary for the additional measurement is transmitted to the inspection terminal 1, and if necessary, the data is acquired via the input / output means 13 and returned.

  In other words, the inspection server 3 stores data in which systematic sorting for separating and extracting failure locations is performed in correspondence with combinations of blinking lamps according to the table T3, and the blinking states of the lamps of the distribution boards 41 to 4n. The history and statistical data of which part of the classification has failed corresponding to the failure mode indicated by is stored, and the failure mode is further subdivided by comparing and referring to the classification data and the history data. The failure part of the switchboard, for example, a unit, a board, a periodic replacement part, etc. is specified in association with the history.

  For example, when the lamps L1 and L3 are lit, it is in the failure mode A. In this case, either one of the units U1 and U3 (not shown) or one of them fails or a signal from the units U1 and U2 is sent. The fact that any of U5 to be added and processed is broken is stored as sorting data.

  Further, in the switchboard 41, in the case of the failure mode A as the repair history, the unit U1 has never failed, but the unit U3 has failed three times and the unit U5 has failed once as history data. Therefore, when the CPU 32 further examines the data of each failure occurrence interval, the unit U3 resets once every three months. Therefore, the CPU 32 determines that the same possibility is high again and determines that the unit U3 has failed. The failure is determined by the procedure.

  That is, it is assumed that the CPU 32 determines that a failure part candidate is created from the trouble data generated in the distribution board 41 and the other distribution boards 42 to 4n, and that additional data is unnecessary for specifying the failure part ( When step S14 is No), the determination result of the faulty part is transmitted to the inspection terminal 1 via the network (step S15).

  Also, if the CPU 32 determines that additional data is necessary (Yes in step S14), a candidate for a faulty part (here, units U3 and U5) is generated and transmitted to the inspection terminal 1 via the network ( Step S16). In that case, additional inspection work information for operating a switch, dial, etc. for further confirming the operation of the unit 3 on the switchboard 41 is read from the database means 31 and transmitted to the inspection terminal 1 according to a preset procedure (step S17). To do.

  When a determination result or a candidate for a faulty part is transmitted from the inspection server 3 to the inspection terminal 1, the determination result, candidate, or additional inspection information is displayed on the display of the input / output means 13 of the inspection terminal 1 ( Step S18).

The inspection terminal 1 returns inspection data corresponding to the additional inspection information, for example, data obtained by measuring the voltage at the inspection point TP1 to the inspection server 3 (step S19). The inspection server 3 compares the received additional inspection data with the table T1 and the like in step S12, and notifies the inspection terminal 1 of the determination result obtained, for example, unit U3 as a failure (step S16).
In addition, the inspector reads the display in step S18, and if data is necessary for further inspection, it is required from the database unit 31 by a predetermined read command by the input / output unit 13 or a Web input screen displayed on the display. A request for reading the repair or additional inspection data is transmitted to the inspection server 3.

  When the CPU 32 of the inspection server 3 receives this command or data request via the communication unit 33, the CPU 32 reads out the corresponding failure determination, repair method, or history data related to the repair from the database unit 31, and additional inspection information. To the terminal 1 for inspection. In the inspection terminal 1, steps S18 and S19 are executed. The above inspection and failure determination are performed, and reset, repair, etc. are executed as necessary (S20).

  In the above description, the emergency work corresponding to the alarm has been described as an example, but the same effect can be obtained in a periodic inspection or the like. For example, it is possible to assist in correctly checking the distribution board 41 to be inspected and performing a cyclic measurement.

  Further, the CPU 32 compares the data acquired by the inspection by the image recognition with the reference value stored in the database means 31 in advance, and when it is an abnormal value, performs additional processing as the measurement data as statistical data. In addition, a new alarm may be generated.

  According to the embodiment of the present invention described above, the following effects can be obtained.

  Refer to the position information and database of the distribution board 4 acquired by the GPS receiver 11 or the distribution board under inspection based on the identification information of the distribution board read from the identification mark of the distribution board recognized when the GPS receiver 11 cannot identify the distribution board. It is possible to specify correctly.

  Since data is acquired from the switchboard by image recognition, it is possible to prevent erroneous entry by the inspector and occurrence of inspection omissions. In addition, it is possible to transmit the determination result of the failed part or the candidate of the failed part to the inspector by comparing and comparing the data acquired from the inspection terminal 1 and the past data of the database of the inspection server 3. It is possible to prevent the occurrence of judgment mistakes by employees.

  Further, it is possible to assist in determining the faulty part by refining additional information necessary for the inspector from trouble information generated in other switchboards read from the database and transmitting it from the inspection server 3 to the inspection terminal 1. .

  Acquire a small amount of inspection data without burdening the inspector by image recognition, and if necessary to determine the faulty part, prompt the operator for additional measurements from the acquired data via the inspection terminal 1, Data can be acquired in stages.
