Hereinafter, the first embodiment of the equipment inspection support system will be described in detail with reference to FIGS. 1 to 9.

FIG. 1 schematically shows the configuration of the equipment inspection support system 100 according to the first embodiment. The equipment inspection support system 100 of the present embodiment is, for example, a system that provides information for supporting the inspection work of the worker when the worker inspects the equipment in the factory.

As shown in FIG. 1, the device inspection support system 100 includes a sensor unit 10 held by an operator, a data collector 20, a tablet terminal 30 as an information processing device, and a position detection device 40 installed in a factory. And a sensor 45 in the factory, and a server 50 as an equipment inspection support device connected to each device via the network 80.

The sensor unit 10 has various sensors (microphone, vibration sensor, etc.), and executes a process of detecting sound, vibration, or the like according to an operation of an operator or automatically. It is assumed that the sensor unit 10 has a position detection device such as GPS (Global Positioning System).

The data collector 20 is connected to the sensor unit 10 and has a function of collecting the detected value (sensor data) detected by the sensor unit 10 and transmitting the detected value (sensor data) to the server 50 via the network 80. The data collector 20 also has a function of acquiring position information from the position detection device of the sensor unit 10 and transmitting the sensor data as the collected position information to the server 50 in a state associated with the sensor data.

The tablet terminal 30 is a terminal carried by an operator when performing inspection work. The tablet terminal 30 receives the information of the result of the inspection work input by the worker and transmits it to the server 50. Further, the tablet terminal 30 receives and outputs information transmitted from the server 50 to support the inspection work. The tablet terminal 30 may transmit the detection value (sensor data) and the position information detected by the various built-in sensors to the server 50.

The position detection device 40 is a beacon, a camera, or the like installed in the factory, and has a function of detecting the position of an operator. The detection result by the position detection device 40 is transmitted to the server 50. The position detection device 40 may acquire the position information detected by the position detection device of the sensor unit 10 or the tablet terminal 30, and treat the acquired position information as the position information of the operator. The position detection device 40 may be a device held by an operator, including a GPS (Global Positioning System) sensor and the like.

The factory sensor 45 is various sensors installed in the factory, and has a function of detecting sound, vibration, and other information in the factory. It is assumed that the in-factory sensors 45 are provided at a plurality of locations in the factory, and the positions of the in-factory sensors 45 are known in advance.

The server 50 acquires and manages the detected values (sensor data) detected by the sensor unit 10, the factory sensor 45, the tablet terminal 30, and the like. Further, the server 50 acquires and manages the information of the result of the inspection work transmitted from the tablet terminal 30. Further, the server 50 identifies the information for supporting the inspection work of the worker based on the managed information, and outputs the information to the tablet terminal 30 at an appropriate timing.

FIG. 2 shows an example of the hardware configuration of the server 50. As shown in FIG. 2, the server 50 includes a CPU (Central Processing Unit) 90, a ROM (Read Only Memory) 92, a RAM (Random Access Memory) 94, a storage unit (here, an HDD (Hard Disk Drive)) 96, and a network. It includes an interface 97, a drive 99 for a portable storage medium, and the like. Each component of the server 50 is connected to the bus 98. In the server 50, the function shown in FIG. 3 is realized by the CPU 90 executing the program stored in the ROM 92 or the HDD 96 or the program read from the portable storage medium 91 by the portable storage medium drive 99. Note that FIG. 3 also shows a detection value DB (database) 60 as a first storage unit and an inspection work support DB 62 as a second storage unit stored in the HDD 96 or the like of the server 50.

FIG. 3 shows a functional block diagram of the server 50. As shown in FIG. 3, the server 50 functions as an inspection work information acquisition unit 52, a sensor data acquisition unit 54, a learning unit 56, and an information providing unit 58 by executing a program.

The inspection work information acquisition unit 52 is information on the result of the inspection work input by the operator from the tablet terminal 30 (for example, information on the inspection result such as "there is a failure in the piping" or information on the work result such as "replacement of the valve"). Is transmitted, the transmitted information is acquired and input to the learning unit 56.

The sensor data acquisition unit 54 acquires the detection values (sensor data) of various sensors and the position information of the sensors when the sensor data is detected from the sensor unit 10, the tablet terminal 30, the factory sensor 45, and the like, and detects the detection value DB60. It is stored in the information providing unit 58 or input to the information providing unit 58. FIG. 4A is a diagram showing an example of the arrangement of equipment in the factory and showing the position information (position coordinates) of the sensor. Further, FIG. 4B is a diagram showing an example of the data structure of the detected value DB60. As shown in FIG. 4B, the detected value DB 60 has fields of “sensor”, “position information”, and “sensor data (time, value)”. In the "sensor" field, the identification information of the sensor that detected the sensor data is stored. In the "position information" field, position information when the sensor detects sensor data is stored. For example, when the sensor data is detected at the position shown in FIG. 4A, the coordinates (X, Y) are stored in the “sensor” field as the position information. In the "sensor data (time, value)" field, the time when the sensor data is detected and the sensor data (actual measurement value) are stored.

When the learning unit 56 acquires the information of the inspection work result from the inspection work information acquisition unit 52, the learning unit 56 associates the acquired information with the data stored in the detection value DB 60 and stores it in the inspection work support DB 62. .. At the time of this storage, the learning unit 56 analyzes the tendency of the sensor data, and also stores the analysis result in the inspection work support DB 62. The analysis performed by the learning unit 56 is, for example, a pattern analysis, a correlation analysis, or the like. Here, the information on the result of the inspection work acquired by the learning unit 56 includes the information on the device to be inspected and the information on the inspection result and the work result. Therefore, the learning unit 56 acquires the position information of the device based on the information of the device to be inspected, and based on the acquired position information, the predetermined predetermined value before the time when the inspection is performed in the vicinity of the device. Identify the sensor data obtained in time. Then, the learning unit 56 associates the specified sensor data with the information of the result of the inspection work and stores it in the inspection work support DB 62 shown in FIG. As shown in FIG. 5, the inspection work support DB 62 includes "sensor", "position information", "sensor data (time, value)", "time series pattern", "correlation coefficient", and "result of inspection work". It has each field of "information". The sensor identification information is stored in the "sensor" field, and the position information of the sensor that detected the sensor data is stored in the "position information" field. Further, in the field of "sensor data (time, value)", the time when the sensor data is detected and the sensor data (actual measurement value) are stored. Further, the result of the pattern analysis is stored in the field of "time series pattern", the result of the correlation analysis is stored in the field of "correlation coefficient", and the field of "information of the result of inspection work" is stored. , Information on the result of inspection work (information on the result of inspection and work result) is stored.

In the pattern analysis executed by the learning unit 56 in the present embodiment, for example, sensor data (time series data) as shown in FIG. 6A was obtained at a predetermined time before the time when the inspection work was performed. In this case, it is a process of extracting one or a plurality of representative pattern data as shown in FIG. 6B by moving a window as shown by a broken line on the time series data. The learning unit 56 expresses each pattern by an approximate function and stores it in the “time series pattern” field of the inspection work support DB 62.

Further, in the correlation analysis executed by the learning unit 56, for example, the time-series data as shown in FIGS. 7 (a) and 7 (b) are the sensors a and b at a predetermined time before the time when the inspection work is performed. This is a process for obtaining the correlation coefficient of both time-series data immediately before the inspection work is performed. For example, as shown in FIGS. 7 (a) and 7 (b), the time-series data for the day immediately preceding the sensors a and b show a correlated change, and the correlation coefficient is, for example, 0.95. In this case, "0.95" is stored in the "correlation coefficient" field of the inspection work support DB 62 of FIG. 5 as the correlation coefficient of the two sensors a and b.

The inspection work support DB 62 is created every time information on the result of the inspection work is obtained.

Returning to FIG. 3, the information providing unit 58 extracts the sensor data acquired in the vicinity of the worker's position within the immediately preceding predetermined period based on the worker's position information, and refers to the inspection work support DB 62. Confirm the existence of data (same or similar) corresponding to the extracted sensor data. Specifically, the information providing unit 58 acquires and extracts the extracted sensor data from the inspection work support DB 62 at the same or similar position by the same sensor based on the identifier of the acquired sensor and the position information. Identify data that is the same as or similar to the sensor data, and extract information on the results of inspection work associated with the identified data. Then, the information providing unit 58 outputs the extracted information to the tablet terminal 30.

Next, the processing of the server 50 will be described in detail with reference to the flowcharts of FIGS. 8 and 9. FIG. 8 is a flowchart showing the processing of the server 50 in the learning phase, and FIG. 9 is a flowchart showing the processing of the server 50 in the operation phase. The learning phase is a process of creating and updating the inspection work support DB 62, and the operation phase is a process of supporting the inspection work by the operator using the inspection work support DB 62 created and updated in the learning phase.

(About the learning phase)
In the process of FIG. 8, in step S10, the sensor data acquisition unit 54 waits until the sensor data and the sensor position information are transmitted from the data collector 20, the tablet terminal 30, the factory sensor 45, and the like.

When the sensor data and the position information of the sensor are transmitted, the process proceeds to step S12, and the sensor data acquisition unit 54 acquires the sensor data and the position information of the sensor and stores them in the detection value DB 60.

Next, in step S14, the learning unit 56 determines whether or not the information on the result of the inspection work has been transmitted from the tablet terminal 30 to the inspection work information acquisition unit 52. That is, it is determined whether or not the worker executes the inspection work and inputs the information of the result of the inspection work to the tablet terminal 30. If the determination in step S14 is denied, the process returns to step S10. While the determination in step S14 is denied, the processes of acquiring the sensor data and the position information of the sensor and storing the detected value in the DB 60 are repeatedly executed (steps S10 and S12). On the other hand, if the determination in step S14 is affirmed, the process proceeds to step S16. When shifting to step S16, the learning unit 56 acquires information on the result of the inspection work via the inspection work information acquisition unit 52.

When the process proceeds to step S16, the learning unit 56 associates the sensor data with the information on the result of the inspection work, and stores the sensor data together with the position information of the sensor in the inspection work support DB 62. In this case, the learning unit 56 acquires the position information of the device based on the information of the device that has been inspected. It is assumed that the position information of the device is managed by a table (not shown). Then, the learning unit 56 identifies the sensor data obtained at the time of the inspection in the vicinity of the acquired position information. Then, the learning unit 56 associates the specified sensor data with the information of the result of the inspection work and stores it in the inspection work support DB 62 shown in FIG.

Next, in step S18, the learning unit 56 executes pattern analysis and correlation analysis of the sensor data stored in the inspection work support DB 62. The learning unit 56 stores the time-series pattern obtained by the pattern analysis and the correlation coefficient obtained by the correlation analysis in the inspection work support DB 62.

After the process of step S18 is performed, the process returns to step S10.

By repeatedly executing the above processing, the data of the inspection work support DB 62 will increase every time the worker executes the inspection work and inputs the information of the result of the inspection work to the tablet terminal 30. ..

(About the operation phase)
Next, the operation phase will be described. The operation phase may be performed in parallel with the learning phase described above, or the learning phase may be stopped and the operation phase may be executed after collecting the data of the inspection work support DB 62 in the learning phase. ..

In the process of FIG. 9, first, in step S30, the information providing unit 58 measures the position information of the worker. In this case, the information providing unit 58 may acquire the position information of the worker detected by the position detection device 40 (camera, beacon, etc.), or may acquire the position information measured by the tablet terminal 30 or the sensor unit 10. It may be acquired as the position information of the worker.

Next, in step S32, the information providing unit 58 detects the sensor data of the sensor installed in the vicinity of the position or the sensor data in the vicinity of the position in the past (previous predetermined period) based on the position information of the worker. The sensor data of the sensor in which the above is performed is acquired from the detection value DB60.

Next, in step S34, the information providing unit 58 collates the acquired sensor data with the inspection work support DB 62. In this case, the information providing unit 58 performs pattern analysis and correlation analysis on the acquired sensor data. Then, the information providing unit 58 inspects the data having a time series pattern that matches or is similar to the time series pattern obtained by the pattern analysis and a correlation coefficient that matches or is similar to the correlation coefficient obtained by the correlation analysis. Specified in support DB 62.

Next, in step S36, the information providing unit 58 determines the degree of coincidence between the time-series pattern of the acquired sensor data and the time-series pattern of the specified data, and the correlation coefficient of the acquired sensor data and the correlation coefficient of the specified data. It is determined whether or not there is data whose degree of agreement with is equal to or greater than the threshold value. If the determination in step S36 is denied, the process returns to step S30 without transmitting anything to the tablet terminal 30. On the other hand, if the determination in step S36 is affirmed, the process proceeds to step S38, and the information providing unit 58 transmits information on the result of the inspection work associated with the data whose degree of agreement is equal to or greater than the threshold value to the tablet terminal 30. To do.

For example, information of "there is a failure in the piping and the valve is replaced" as shown in FIG. 5 is transmitted to the tablet terminal 30. Therefore, on the display screen of the tablet terminal 30, "There is a failure in the piping and the valve is replaced" is displayed. A worker who sees the tablet terminal 30 with such a display indicates that the displayed inspection or work has been performed when a device existing in the vicinity in the past is in the same state as the present. Since it can be known, inspection work can be easily performed.

As described in detail above, according to the first embodiment, the sensor data acquisition unit 54 acquires the sensor data detected by the sensor and the position information of the sensor when the sensor data is detected. Then, the acquired sensor data and position information are stored in the detection value DB 60 (S12). Further, when the inspection work information acquisition unit 52 acquires the information on the result of the inspection work of the device to be inspected (S14: affirmative), the learning unit 56 is in the vicinity of the device to be inspected in a predetermined period before the inspection work is performed. The sensor data acquired by the sensor and the position information of the sensor are read from the detected value DB60, and the analysis result of the read sensor data and the position information of the sensor are associated with the information of the result of the inspection work for inspection work. It is stored in the support DB 62 (S16, S18). Then, the information providing unit 58 uses the sensor data acquired in the vicinity of the worker in a predetermined period before the position information is detected based on the position information of the worker detected by the position detection device 40, and the sensor. The position information of the sensor when the data is detected is extracted from the detected value DB60, and the inspection work support DB62 is referred to, and the result of the inspection work corresponding to the analysis result of the extracted sensor data and the position information of the sensor. Information is specified and output to the tablet terminal 30 (FIG. 9). As described above, in the first embodiment, the past sensor data is obtained when the sensor data having a tendency similar to the sensor data detected in the past in the vicinity of the worker is obtained based on the position of the worker. Information on the result of the inspection work associated with is transmitted to the tablet terminal 30. Therefore, the operator can easily recognize the state of the device by looking at the information transmitted to the tablet terminal 30 when approaching the device to be inspected.

<< Second Embodiment >>
Next, the second embodiment will be described with reference to FIG.

In the second embodiment, as in the first embodiment, the information providing unit 58 performs the process (operation phase) shown in FIG. 10A on the premise that the sensor data is stored in the detected value DB 60. Execute.

In the process of FIG. 10A, first, in step S40, the information providing unit 58 detects the position information of the worker. In this case, as in the first embodiment, the information providing unit 58 may acquire the position information of the worker detected by the position detecting device 40 (camera, beacon, etc.), or the tablet terminal 30 or the sensor unit. The position information detected by 10 may be acquired as the position information of the operator.

Next, in step S42, the information providing unit 58 determines whether or not the position information has changed by a predetermined value or more. That is, it is determined whether or not the worker has moved. If the determination in step S42 is denied, the process returns to step S40, but if the determination is affirmed, the process proceeds to step S44.

When the process proceeds to step S44, the information providing unit 58 extracts the sensor data acquired in the past in the vicinity of the worker from the detected value DB 60 based on the position information of the worker.

Next, in step S46, the information providing unit 58 transmits the extracted sensor data to the tablet terminal 30. As a result, the tablet terminal 30 can display the sensor data acquired in the past at the position where the worker exists, or the sensor data acquired by the sensor in the vicinity of the position. In this case, for example, as shown in FIG. 10B, by displaying the extracted sensor data on the tablet terminal 30, the operator can know the long-term or short-term changes in the sensor data. This makes it easier to notice changes (abnormalities, etc.) in the equipment due to the discrepancy between recent data and past data and the tendency of changes. Further, for example, when the extracted data is sound data, the tablet terminal 30 reproduces the sound data obtained over a long period of time at high speed in a short time. This makes it easier for the operator to notice changes in equipment (abnormalities, etc.) from changes in sound. When the sensor data is displayed on the tablet terminal 30, not only the raw data but also the spectrum after frequency analysis and the correlation coefficient of a plurality of sensor data may be presented. In this case, it is possible to give the operator an awareness that cannot be discriminated from the five senses or raw data.

The second embodiment can be implemented in parallel with the first embodiment described above.

<< Third Embodiment >>
Next, the third embodiment will be described in detail with reference to FIGS. 11 to 13.

The third embodiment presents an appropriate inspection route to the operator, and can be implemented in combination with the first embodiment and the second embodiment.

FIG. 11 is a flowchart showing an inspection route setting process. Hereinafter, the inspection route setting process will be described with reference to FIG.

In the process of FIG. 11, first, in step S100, the information providing unit 58 waits until the inspection route setting timing is reached. In this case, the inspection route setting timing shall be a predetermined time before the operator performs the inspection (for example, before the start of daily work).

When the determination in step S100 is affirmed and the process proceeds to step S102, the learning unit 56 calculates the inspection time for each device of the worker based on the transition of the position information of the worker. In this case, the time that the worker has been present in the vicinity of the device is totaled, and the average time for each device is calculated. FIG. 12A shows a table summarizing the inspection time of each device of each worker. For example, worker α is good at inspecting equipment A because it takes 0.2 hours to inspect equipment A, 0.5 hours to inspect equipment B, and 0.3 hours to inspect equipment C. , It turns out that the inspection of equipment B is not good. Further, for example, the worker β takes 0.5 hours to inspect the equipment A, 0.1 hours to inspect the equipment B, and 0.3 hours to inspect the equipment C. It turns out that he is not good at it and is good at inspecting equipment B.

Next, in step S104, the learning unit 56 determines the inspection frequency based on the fluctuation of the sensor data. For example, as shown in FIG. 12 (d), it is assumed that the sensor data (approximate function) continues to decrease from the initial value, but the sensor data returns to the initial value at a certain time and starts to decrease again from there. .. In this case, it can be estimated that the time from when the initial value is shown to when the initial value is shown again is the maintenance cycle (abnormal cycle). Therefore, as shown in the table of FIG. 12B, the learning unit 56 sets the inspection frequency to be shorter than the estimated abnormal cycle. For example, in FIG. 12B, since the device A has an abnormal cycle of 3 months, the learning unit 56 sets an interval shorter than the abnormal cycle (for example, once every 10 days) as the inspection frequency. Further, since the device B has an abnormal cycle of one month, the learning unit 56 sets an interval shorter than the abnormal cycle (for example, twice every 7 days) as the inspection frequency. Further, since the device C has an abnormal cycle of one week, the learning unit 56 sets an interval shorter than the abnormal cycle (for example, once a day) as the inspection frequency.

Next, in step S106, the learning unit 56 determines the inspection route of each worker based on the inspection time of each device by each worker and the inspection frequency of each device. Specifically, the learning unit 56 identifies the equipment to be inspected on that day with reference to FIG. 12B, and allocates the equipment to be inspected to each worker based on FIG. 12A. .. Then, based on the positional relationship (map information) of each device, the shortest route around the device assigned to each worker is determined. FIG. 12C shows an example of the inspection route (shortest route) of each worker.

Next, in step S108, the learning unit 56 stores the inspection route in the database. Specifically, the table shown in FIG. 12 (c) is stored in the database. When the processing up to step S108 is completed as described above, the process returns to step S100. Returning to step S100, the learning unit 56 waits until the setting timing of the inspection route is reached, and at the stage when the setting timing is reached, the processes of steps S102 to S108 are executed in the same manner as described above.

Next, the process of providing the inspection route to the worker will be described in detail with reference to FIG. In the process of FIG. 13, first, in step S120, the information providing unit 58 waits until there is an inquiry from the worker. That is, when the operator inputs the request for the inspection route on the tablet terminal 30 and the information providing unit 58 receives the input, the process proceeds to step S122.

When the process proceeds to step S122, the information providing unit 58 determines whether or not it is the timing to start the inspection. That is, it is determined whether or not it is within the predetermined time range from the start time of the day. If the determination in step S122 is denied, the process proceeds to step S126, but if the determination is affirmed, the process proceeds to step S124.

When the process proceeds to step S124, the information providing unit 58 transmits the inspection route (see (see FIG. 12C)) stored in the database to the tablet terminal 30 carried by the worker, whereby the worker can perform the day. The inspection route can be known on the tablet terminal 30.

On the other hand, when the determination in step S122 is denied and the process proceeds to step S126, the information providing unit 58 acquires the position information of the worker from the position detecting device 40. Next, in step S128, the information providing unit 58 adjusts the inspection route based on the position information and transmits it to the tablet terminal 30. Specifically, the information providing unit 58 identifies which device the worker is in the vicinity of the worker from the current position information of the worker, and sets the inspection route shown in FIG. 12 (c) to the device in the vicinity of the worker. Is changed to the inspection route starting from, and is transmitted to the tablet terminal 30. As a result, the worker can know the inspection route that needs to be visited from now on on the tablet terminal 30.

As described above, after the processing of step S124 or S128 is performed, the process returns to step S120, and the above-described processing is repeatedly executed.

As can be seen from the explanations so far, the information providing unit 58 of the present embodiment identifies a calculation unit that calculates the time required for the operator to inspect each device, a specific unit that specifies the inspection frequency of each device, and a calculation unit. Based on the processing result of the unit, the function as an information providing unit that sets and outputs the inspection route of the worker is realized.

As described in detail above, according to the third embodiment, the information providing unit 58 is based on the change in the position information of the worker detected by the position detection device 40 and the position information of the device to be inspected. Then, the operator calculates the inspection time of each device (S102), determines the inspection frequency of each device based on the change in the sensor data detected by the sensor (S104), and determines the inspection time of each device and each device. The inspection route of the worker is determined and output based on the inspection frequency of. As a result, according to the third embodiment, the inspection route is determined based on the automatically calculated inspection time of each device by each worker and the inspection frequency of each device, so that unnecessary and urgent inspection is performed. Can be reduced and necessary inspections can be assigned to appropriate workers (workers who are good at it). Therefore, by providing each worker with an appropriate inspection route capable of improving the efficiency of inspection, it is possible to appropriately support the inspection work by each worker.

The above processing function can be realized by a computer. In that case, a program that describes the processing content of the function that the processing device should have is provided. By executing the program on a computer, the above processing function is realized on the computer. The program describing the processing content can be recorded on a computer-readable recording medium (however, the carrier wave is excluded).

When a program is distributed, it is sold in the form of a portable recording medium such as a DVD (Digital Versatile Disc) or a CD-ROM (Compact Disc Read Only Memory) on which the program is recorded. It is also possible to store the program in the storage device of the server computer and transfer the program from the server computer to another computer via the network.

The computer that executes the program stores, for example, the program recorded on the portable recording medium or the program transferred from the server computer in its own storage device. Then, the computer reads the program from its own storage device and executes the processing according to the program. The computer can also read the program directly from the portable recording medium and execute the processing according to the program.
