[0011] Embodiment 1 Fig. 1 is a functional block diagram of a patrol inspection work evaluation system according to the present embodiment. As shown in Fig. 1, a patrol inspection work evaluation system 500a according to the present embodiment includes a position detection terminal 1a, an operation terminal 2a, and a patrol inspection work evaluation device 3a. Fig. 2 is a schematic diagram showing a flow of a patrol inspection using the patrol inspection work evaluation system 500a according to the present embodiment. First, an overview of the patrol inspection work evaluation system 500a shown in FIG. 1 will be described, and the details of each component shown in FIG. 1 will be described later.

[0012] In this embodiment, a worker w wears the position detection terminal 1a and carries the operation terminal 2a and performs a patrol inspection. The position detection terminal 1a detects the position and orientation of the worker w at each of a plurality of times, for example, every second, and stores the detected position and orientation in association with the time of detection as position detection information. The operation terminal 2a receives the inspection results of the equipment to be inspected by the worker w, stores the inspection results as an inspection record, and also stores the inspection result input time, which is the time when the inspection results were input, as inspection record input information.

[0013] The patrol inspection work evaluation device 3a acquires the position detection information stored in the position detection terminal 1a and acquires the inspection result input time stored in the operation terminal 2a. Then, the patrol inspection work evaluation device 3a extracts the position of the worker w at the inspection result input time from the acquired position detection information as the inspection work position, and extracts the orientation of the worker w at the inspection result input time from the position detection information as the inspection work orientation. In addition, the patrol inspection work evaluation device 3a calculates the distance from the extracted inspection work position to the position of the equipment to be inspected that is stored in advance, and the direction from that inspection work position to the equipment to be inspected, and evaluates that the inspection work has been performed correctly if the calculated distance is within a predetermined range, or if the difference between the calculated direction and the extracted inspection work direction is within a predetermined range.

[0014] 1, the position detection terminal 1a, the operation terminal 2a, and the patrol inspection work evaluation device 3a are configured as separate devices, and the communication unit 30a of the patrol inspection work evaluation device 3a functions as a position detection information acquisition unit that acquires the above-mentioned position detection information from the position detection terminal 1a. The communication unit 30a also functions as an inspection record input information acquisition unit that acquires the above-mentioned inspection result input information including the inspection result input time from the operation terminal 2a.

[0015] Fig. 3 is a flow chart showing the flow of the visual inspection shown in Fig. 2. The flow of the visual inspection will be explained below with reference to Figs. 2 and 3.

[0016] First, in the office F2, the worker w wears the position detection terminal 1a and carries the operation terminal 2a to start the patrol inspection. When the worker w arrives at the inspection work site F1 where the equipment to be inspected is installed, he performs the inspection work of the equipment to be inspected. This inspection work is performed by the worker w inspecting the equipment to be inspected and inputting the inspection results into the operation terminal 2a (step FC101). The operation terminal 2a stores the inspection results input by the worker w as an inspection record, and also stores the inspection result input time, which is the time when the inspection result was input, as inspection record input information.

[0017] After completing the inspection work, the worker w returns to the office F2 where the manager s is, and returns the position detection terminal 1a and the operation terminal 2a. At that time, the worker w reports the completion of the patrol inspection to the manager s, and also reports any other matters to be reported. The manager s collects the position detection terminal 1a and the operation terminal 2a returned by the worker w (step FC102). The position detection terminal 1a detects the position and orientation of the worker w at a predetermined time interval, for example, every second, throughout the entire period from when the worker w leaves the office F2 to when he returns, and stores the detected position and orientation as position detection information in association with the time of detection.

[0018] Next, the manager s connects the position detection terminal 1a and the operation terminal 2a to the patrol inspection work evaluation device 3a. This connection may be either wired or wireless. The patrol inspection work evaluation device 3a acquires position detection information from the position detection terminal 1a and also acquires inspection record input information including the inspection result input time from the operation terminal 2a, and evaluates whether the inspection work has been performed correctly or not from the acquired information as described above, and displays the evaluation result. The manager s checks whether the inspection work has been performed correctly or not by looking at the evaluation result displayed by the patrol inspection work evaluation device 3a (step FC103).

[0019] The inspection work evaluation device 3a may also acquire and display the inspection results of the equipment to be inspected from the operation terminal 2a. Furthermore, if there are other factors that should be considered to indicate that the inspection work has not been performed correctly, such as the inspection results being input incorrectly, the inspection work evaluation device 3a may display the above-mentioned evaluation results after correcting them for those factors.

[0020] Next, the hardware configurations of the position detection terminal 1a, the operation terminal 2a, and the patrol inspection work evaluation device 3a will be described. Fig. 4 is a hardware configuration diagram of the operation terminal 2a according to this embodiment. The operation terminal 2a is, for example, a tablet-type terminal having a display 101 and capable of inputting by touching the screen with a finger or a pen. The hardware configuration of the patrol inspection work evaluation device 3a is also similar to that of Fig. 4, but the patrol inspection work evaluation device 3a may be operated as a stationary device in an office, and may be configured as a stationary terminal instead of a tablet type. Input to the patrol inspection work evaluation device 3a may be performed by a mouse, a keyboard, voice input, or the like.

[0021] In FIG. 4, the storage device 103 stores a basic OS (Operating System) that controls the operation terminal 2a, and also stores a program for implementing the functions of the operation terminal 2a according to this embodiment. The storage device 103 is, for example, a solid state drive (SSD) or a hard disk drive. A central processing unit (CPU) 102 in FIG. 4 executes the basic OS and the program. The inspection records stored in the operation terminal 2a are stored in this storage device 103. This storage device 103 may be an external recording medium such as a card type that is detachable from the operation terminal 2a. The display 101 in FIG. 4 displays a screen for the worker w to input the inspection results.

[0022] The hardware configuration of the patrol inspection work evaluation device 3a is also similar to the hardware configuration in Fig. 4. A program for realizing the functions of the patrol inspection work evaluation device 3a according to this embodiment is stored in the storage device 103 in Fig. 4, and the display 101 in Fig. 4 displays the evaluation result of whether the inspection work was performed correctly or not, the inspection result acquired from the operation terminal 2a, and the like.

[0023] FIG. 5 is a hardware configuration diagram of the position detection terminal 1a according to this embodiment. The position detection terminal 1a also includes a CPU 201 and a storage device 202, as in FIG. 4, and the storage device 202 stores a program for implementing the functions of the position detection terminal 1a according to this embodiment. The position detection terminal 1a further includes a GPS (Global Positioning System, Global Positioning Satellite) signal receiving device and a beacon receiving device (not shown) as a position detection unit shown in FIG. 1, and stores the current position of the terminal detected from the received signal as the position of the worker w in association with the time of detection in the storage device 202. In FIG. 5, the position detection terminal 1a does not include a display unit, but may further include a display unit that displays the detected current position, etc.

[0024] In this embodiment, the position detection terminal 1a, the operation terminal 2a, and the patrol inspection work evaluation device 3a are configured as separate devices, but the function of the position detection terminal 1a may be incorporated into the operation terminal 2a, and the position detection terminal 1a and the operation terminal 2a may be realized as an integrated terminal. Also, the functions of the position detection terminal 1a and the patrol inspection work evaluation device 3a may be incorporated into the operation terminal 2a, and they may be configured as an integrated terminal. In that case, as a hardware configuration for realizing each function, a CPU, a storage device, etc. may be shared by multiple functions.

[0025] Next, detailed explanations will be given of the configurations of the position detection terminal 1a, the operation terminal 2a, and the patrol inspection work evaluation device 3a shown in Fig. 1. First, the configuration of the position detection terminal 1a shown in Fig. 1 will be given. In Fig. 1, the position detection terminal 1a has a position detection unit 10a, a position detection information storage unit 11a, an orientation detection unit 12a, and a communication unit 13a.

[0026] The position detection unit 10a numerically detects the position of its own terminal, i.e., the position detection terminal 1a, by receiving, for example, a GPS signal or a signal from a beacon transmitter installed near the equipment to be inspected. Since the worker w wears the position detection terminal 1a, the position detected by the position detection terminal 1a can be used as the detection result of the position of the worker w.

[0027] More specifically, when the position detection unit 10a detects the position using GPS signals, it receives GPS signals from multiple GPS satellites and detects the position of the worker w in terms of latitude and longitude from the GPS signals. When the position detection unit 10a detects the position using beacon signals, one or more beacon transmitters are placed in advance near the location where the patrol inspection work is performed, and when the worker w passes by a beacon transmitter, the position detection unit 10a receives the beacon signal. The position detection unit 10a prestores a position corresponding to an ID included in the received beacon transmission, and detects the position as the position of its own terminal, i.e., the position of the worker w. Alternatively, the position detection unit 10a may receive beacon signals from multiple beacon transmitters and detect the position of its own terminal relative to the positions of the multiple beacon transmitters from the reception strength of the multiple beacon signals.

[0028] Here, the position detection method used by the position detection unit 10a is described as using GPS signals or beacon signals, but is not limited thereto, and other methods may be used as long as they can numerically detect the position of the worker w, such as latitude and longitude, a polar coordinate system, a distance from a reference point, a rotation angle, etc. The position detection unit 10a performs such position detection of the worker w at multiple times, for example, every second, and outputs the detected position of the worker w to the position detection information accumulation unit 11a in association with the time of detection.

[0029] The orientation detector 12a also detects how much the visual direction of the worker w has rotated from a predetermined reference direction as the orientation of the worker. The orientation detector 12a performs such detection of the orientation of the worker at multiple times, for example, every second, and outputs the detected orientation of the worker to the position detection information storage unit 11a in association with the time of detection.

[0030] The method of detecting the orientation of the worker in the orientation detector 12a is, for example, to detect the geomagnetic direction from south to north, and detect the difference between the geomagnetic direction and the orientation of the orientation detector 12a as the orientation of the worker. Alternatively, a gyro sensor or an acceleration sensor may be used, and the orientation detected by the sensor at a certain point in time may be set as a reference direction, and the amount of rotation from the reference direction may be detected as the orientation of the worker. There are no limitations on the detection method of the orientation detector 12a as long as it can numerically detect the orientation of the worker.

[0031] It is preferable that the position detection terminal 1a is worn as fixedly as possible on the body of the worker so that the orientation detection unit 12a can accurately detect the orientation of the worker and the orientation detection unit 12a also rotates according to the rotation of the worker's body. In FIG. 2, the position detection terminal 1a is illustrated as a glasses-type terminal worn on the face of the worker, but it may be worn on the torso or other part of the worker other than the face. When the position detection terminal 1a detects only the position of the worker and does not detect the orientation of the worker, the position detection terminal 1a may be worn by the worker to such an extent that the position of the position detection terminal 1a can be regarded as the position of the worker.

[0032] FIG. 6 shows an example of position detection information accumulated by the position detection information accumulation unit 11a according to the present embodiment. The position detection information accumulation unit 11a stores the position of the worker w detected by the position detection unit 10a and the orientation of the worker w detected by the orientation detection unit 12a as position detection information in association with the time of detection. FIG. 6 illustrates a case in which the time at which the position detection unit 10a detects the position of the worker and the time at which the orientation detection unit 12a detects the orientation of the worker coincide with each other, but the detection times of the position detection unit 10a and the orientation detection unit 12a may be different from each other. In FIG. 6, the position of the worker at each time every second is stored in latitude and longitude, and the orientation of the worker at the same time is stored in an angle of difference from the geomagnetic direction.

[0033] 1 transmits the position detection information stored in the position detection information storage unit 11a to the communication unit 30a of the patrol inspection work evaluation device 3a. As a communication interface of this communication unit, any wired or wireless communication method can be used, such as a wireless LAN such as IEEE802.11a / b / g / n, Bluetooth (registered trademark), or a mobile phone network such as the fifth generation mobile communication system (5G).

[0034] Next, a description will be given of the configuration of the operation terminal 2a shown in Fig. 1. The operation terminal 2a has an inspection record input unit 20a, an inspection record storage unit 21a, an inspection record input information accumulation unit 22a, and a communication unit 23a.

[0035] The inspection record input unit 20a is an input device for an operator to input the inspection results of the equipment to be inspected, and is, for example, a touch panel of a tablet terminal. Fig. 7 shows an example of a screen 300 for inputting the inspection results, which is displayed on the touch panel. In Fig. 7, the screen 300 includes an inspection target equipment selection list 301, an inspection record history selection list 302, a date and time input box 303, a status selection box 304, an inspection record input text box 305, and an information update button 306, but any input method may be used as long as it is an interface that allows the inspection results to be input.

[0036] The input operation of the inspection results by worker w in Figure 7 will be described. The inspection target equipment selection list 301 is a drop-down list for inputting the name / ID of the equipment to be inspected, and the name / ID of each piece of equipment to be inspected is registered in advance here. From this inspection target equipment selection list 301, the worker w selects the name of the equipment to be inspected, for which the inspection results are to be input.

[0037] The inspection record history selection list 302 is a drop-down list for switching between a mode for inputting new inspection results and a mode for correcting inspection results input in the past. When inputting new inspection results, the worker w leaves the inspection record history selection list 302 unselected, and when correcting past inspection results input, the inspection record history selection list 302 is set to a state in which options such as "Last time" and "The time before last" are displayed. When the worker w selects, for example, "Last time" in the inspection record history selection list 302, the contents of the inspection record input last time are displayed in the date and time input box 303, the status selection box 304, and the inspection record input text box 305, and the worker w can correct the contents.

[0038] The date and time when the inspection was carried out is input in the date and time input box 303. Here, the work procedure manual or the like instructs that the worker w should input the inspection results into this screen 300 during or immediately after the inspection, and the worker w inputs the date and time of input in the date and time input box 303. By pressing an information update button 306 (described later), the date and time at the time of pressing the button may be automatically input into this date and time input box 303.

[0039] The status selection box 304 is a drop-down list for inputting the status of the equipment to be inspected, which is the inspection result, and has pre-registered options such as the appearance of the equipment to be inspected (e.g., "no damage", "damage present") and the status of the equipment to be inspected during operation (e.g., "no abnormal noise", "abnormal noise present"). The worker w uses this drop-down list to select the status of the equipment to be inspected, which is the inspection result of this time.

[0040] The inspection record input text box 305 is a text box for inputting other information about the current inspection result. In addition to the selection in the status selection box 304, when the worker w wants to make further comments about the status of the equipment to be inspected, the worker w inputs the comments in the inspection record input text box 305. When the worker w has finished inputting the inspection results into the screen 300, he / she presses the information update button 306.

[0041] When the information update button 306 is pressed, the contents input to the screen 300 are stored in the inspection record storage unit 21a and the inspection record input information accumulation unit 22a in Fig. 1. More specifically, when the information update button 306 is pressed, the contents input to the inspection target equipment selection list 301, the date and time input box 303, the status selection box 304, and the inspection record input text box 305 are stored as an inspection record in the inspection record storage unit 21a. In addition, the contents input to the inspection target equipment selection list 301 and the inspection record history selection list 302 are associated with the input time of the inspection result and stored as inspection record input information in the inspection record input information accumulation unit 22a.

[0042] When the information update button 306 is pressed while “Previous” is selected in the inspection record history selection list 302, the “previous” inspection record already stored in the inspection record storage unit 21a in FIG. 1 is modified with the contents entered this time in the date and time input box 303, the status selection box 304, and the inspection record input text box 305.

[0043] Fig. 8 is an example of an inspection record stored in the inspection record storage unit 21a of Fig. 1. In Fig. 8, "inspection date" is the date input in the date and time input box 303 of Fig. 7. "Equipment name / ID" in Fig. 8 is the name / ID of the equipment to be inspected input in the inspection target equipment selection list 301 of Fig. 7. "Equipment status" in Fig. 8 is the status of the equipment to be inspected input in the status selection box 304 of Fig. 7. The inspection record storage unit 21a also stores comments (not shown) input in the inspection record input text box 305 of Fig. 7.

[0044] The inspection record input information accumulation unit 22a stores, as inspection record input information, information regarding the operation performed by the worker w when he entered the inspection record, together with some or all of the inspection record. Fig. 9 shows an example of inspection record input information stored in the inspection record input information accumulation unit 22a. The "inspection record input information" in Fig. 9 is composed of "input time", "input duration", "name of equipment to be inspected and its ID", and "operation type".

[0045] The "input time" in Fig. 9 is the time when the inspection result is input by the worker w, and is, for example, the date and time when the information update button 306 is pressed. This "input time" may be the date and time input by the worker w in the date and time input box 303 in Fig. 7, but it is preferable to increase the reliability of the date and time by setting the date and time when the information update button 306 is pressed as the date and time automatically detected by the program from the OS's internal clock or a GPS signal. This "input time" may be another date and time during the worker w's input of the inspection result, such as the time when the worker w starts inputting the inspection result (for example, the time when the screen 300 is opened).

[0046] "Input time" in Fig. 9 is the time elapsed from when the worker w starts inputting the inspection results to when he finishes inputting the inspection results (for example, when the information update button 306 is pressed). "Operation type" in Fig. 9 stores the "mode for inputting new inspection results" inputted from the inspection record history selection list 302 as "new" and the "mode for correcting previously inputted inspection results" as "correction."

[0047] The communication unit 23a in Fig. 1 transmits the inspection record input information stored in the inspection record input information storage unit 22a to the communication unit 30a of the patrol inspection work evaluation device 3a. As with the communication unit 13a, the communication interface of this communication unit can use any wired or wireless communication method, such as a wireless LAN such as IEEE802.11a / b / g / n, Bluetooth (registered trademark), or a mobile phone network such as the fifth generation mobile communication system (5G). The communication method used by the communication unit 13a of the position detection terminal 1a and the communication method used by the communication unit 23a of the operation terminal 2a may be the same or different from each other.

[0048] Next, the configuration of the patrol inspection work evaluation device 3a shown in FIG. 1 will be described. The patrol inspection work evaluation device 3a includes a communication unit 30a, an inspection record input information storage unit 31a, a position detection information storage unit 32a, a route calculation unit 33a, a route display unit 34a, an equipment information storage unit 35a, a work position extraction unit 36a, a positional relationship calculation unit 37a, a work evaluation unit 38a, and a result display unit 39a.

[0049] The communication unit 30a acquires position detection information from the communication unit 13a of the position detection terminal 1a and stores it in the position detection information storage unit 32a. The communication unit 30a also acquires inspection record input information from the communication unit 23a of the operation terminal 2a and stores it in the inspection record input information storage unit 31a.

[0050] The route calculation unit 33a uses the position detection information stored in the position detection information storage unit 32a to determine the movement route of the worker w, and displays the movement route on the route display unit 34a. Specifically, the positions of the worker w at each time stored in the inspection record input information storage unit 31a are plotted on a map, and an image in which the plots are connected by lines in the order of time is displayed on the route display unit 34a as the movement route of the worker w. At this time, the direction of the worker w at each time stored in the inspection record input information storage unit 31a may be superimposed on each plot with an arrow or the like and displayed. The route display unit 34a and the result display unit 39a may be a single shared display device, or may be separate display devices.

[0051] Fig. 10 is an example of the movement route of the worker w displayed by the route display unit 34a. In Fig. 10, the positions of the worker w at each time stored in the inspection record input information storage unit 31a are plotted as black circles on a map showing equipment i and equipment j that are inspection target equipment, equipment x that is not inspection target equipment, and the plots are connected by lines in the order of time.

[0052] The equipment information storage unit 35a in Fig. 1 stores the position of the equipment to be inspected. In this embodiment, the position of the equipment to be inspected is stored in advance. Fig. 11 shows an example of the position of the equipment to be inspected stored in the equipment information storage unit 35a according to this embodiment. The equipment information storage unit 35a stores the equipment name and ID of the equipment to be inspected, and the position of the equipment to be inspected. In Fig. 11, the position information is expressed using latitude and longitude, but other expression methods may be used.

[0053] The work position extraction unit 36a in Figure 1 reads the inspection result input time of the worker w from the inspection record input information stored in the inspection record input information storage unit 31a, and extracts the position and orientation of the worker w at the inspection result input time from the position detection information of the worker w stored in the position detection information storage unit 32a.

[0054] 12 is a flowchart showing the process flow of the work position extraction unit 36a. In step FC201, the work position extraction unit 36a reads out the inspection result input time of the worker w from the inspection record input information stored in the inspection record input information storage unit 31a. In step FC202, the work position extraction unit 36a extracts the position of the worker w at the inspection result input time from the position detection information of the worker w stored in the position detection information storage unit 32a as the inspection work position.

[0055] More specifically, when the position of the worker w at the time that coincides with the inspection result input time of the worker w is stored in the position detection information stored in the position detection information storage unit 32a, the work position extraction unit 36a extracts the position as the inspection work position. When the position of the worker w at the time that coincides with the inspection result input time is not stored in the position detection information, the work position extraction unit 36a extracts the position of the worker w at the time that is closest to the inspection result input time from the position detection information stored in the position detection information as the inspection work position. Alternatively, the position of the worker w at the time that is closest to the inspection result input time may be extracted as the inspection work position. Alternatively, the inspection work position may be extracted using an arbitrary estimation formula based on the position detection information.

[0056] FIG. 12 illustrates a case where the work position extraction unit 36a extracts the inspection work position of the worker w. However, the same extraction can be performed when the work position extraction unit 36a extracts the orientation of the worker w at the inspection work position.

[0057] The positional relationship calculation unit 37a in Fig. 1 calculates a value related to the positional relationship between the inspection work position of the worker w and the position of the equipment to be inspected. The positional relationship value calculated here is at least one of the following (1) and (2), and in this embodiment, both of the following (1) and (2) are calculated. (1) The distance between the inspection work location and the location of the equipment to be inspected. (2) The angular difference between the direction of the worker w at the inspection work position and the direction from the inspection work position toward the equipment being inspected.

[0058] First, the calculation of the above-mentioned (1) in the positional relationship calculation unit 37a will be described. Fig. 14 shows the flow of the calculation of the above-mentioned (1). The positional relationship calculation unit 37a calculates the distance between the inspection work position extracted by the work position extraction unit 36a and the position of the equipment to be inspected as the positional relationship between the inspection work position and the position of the equipment to be inspected. Fig. 13 shows an example of the distance between the movement path of a worker w and the position of an inspection target facility i. The black plots in Fig. 13 are the positions of the workers, and the white plots are the inspection work positions extracted by the work position extraction unit 36a.

[0059] In step FC301 of FIG. 14, the positional relationship calculation unit 37a calculates the equipment name / ID of the inspection target equipment i and the position L of the inspection target equipment i. i is obtained from the facility information storage unit 35a.

[0060] In step FC302 of FIG. 14, the distance L between the inspection work position extracted by the work position extraction unit 36a and the position of the equipment to be inspected i is calculated. i When the inspection record is corrected, there will be multiple inspection records for the equipment i to be inspected. In other words, there will be multiple inspection work positions for the equipment i to be inspected. Let the number of inspection records for the equipment i to be k (1, 2...k), and let the inspection work positions for the equipment i to be the inspection work positions L i,k The location of the equipment to be inspected i and the location of each inspection work L i,k Distance D i,k For example, in FIG. 13, the inspection work position is the inspection work position L i,1 and L i,2Therefore, the distance between each inspection work position and the equipment to be inspected i is the distance D i,1 and distance D i,2 It is calculated as follows.

[0061] In FC303, when there are multiple inspection work positions for the inspection target equipment i, the distance D i,k In Figure 13, the smallest distance D i,1 and distance D i,2 The smaller of the two distances is D i,1 The positional relationship calculation unit 37a selects this as a value related to the positional relationship. In this way, the positional relationship calculation unit 37a calculates the distance between the inspection work position and the position of the equipment to be inspected as a value related to the positional relationship in accordance with steps FC301 to FC303.

[0062] Next, the calculation of the above-mentioned (2) in the positional relationship calculation unit 37a will be described. The positional relationship calculation unit 37a calculates the angle difference between the orientation of the worker at the inspection work position and the orientation from the inspection work position to the inspection target equipment as the positional relationship between the inspection work position of the worker w and the position of the inspection target equipment.

[0063] 15 shows a flow in which the positional relationship calculation unit 37a calculates the angle difference between the direction of the worker at the inspection work position and the direction from the inspection work position to the inspection target equipment. In FC401 in FIG. 15, the positional relationship calculation unit 37a calculates the direction α i Next, in FC402, the positional relationship calculation unit 37a obtains a direction β i Next, in FC403, the positional relationship calculation unit 37a calculates the worker's orientation α i and the direction of the equipment to be inspected β i The angle difference ω i Calculate.

[0064] In this way, the positional relationship calculation unit 37a calculates the angle difference between the direction of the worker at the inspection work position and the direction of the equipment to be inspected at the inspection work position as a value related to the positional relationship, in accordance with steps FC401 to FC403.

[0065] The positional relationship calculation unit 37a may calculate the following (3) instead of the above-mentioned (2). (3) The minimum angle difference between the direction of the worker w and the direction toward the equipment being inspected within a predetermined period of time from the time the inspection result is input.

[0066] The calculation of the above-mentioned (3) by the positional relationship calculation unit 37a will be described. The positional relationship calculation unit 37a calculates, as the positional relationship between the inspection work position of the worker w and the position of the inspection target equipment, the minimum value of the angle difference between the orientation of the worker w at each time within a predetermined period of time from the inspection result input time and the orientation from the position of the worker w to the inspection target equipment at each time.

[0067] Fig. 16 shows a flow of calculating values ​​related to the positional relationship. Fig. 17 is an example of a diagram showing the position of a worker w who is in a predetermined time range at an inspection target facility i. The black and white plots in Fig. 17 are the positions of the worker w at each time stored in the inspection record input information storage unit 31a, and the white plots are the positions of the worker w within a predetermined time range from the inspection result input time.

[0068] In FC501, the positional relationship calculation unit 37a acquires the inspection result input time for the inspection target equipment i from the inspection record input information storage unit 31a, and extracts the position of the worker w within a predetermined time range centered on the inspection result input time as the inspection work position. However, since the worker w may move away from the inspection target equipment i during that time range, it is also possible to extract only the positions of the extracted workers whose distance from the inspection target equipment i is within a predetermined range.

[0069] For example, in FIG. 17, a predetermined time range is set to, for example, ±10 minutes from the inspection result input time, and a circle with a radius of M from the inspection target equipment i is set to a predetermined distance M range. Then, from the position detection information stored in the position detection information storage unit 32c, the position and orientation of the worker w within that time range and within that distance M range are extracted. The size of this radius M may be different for each inspection target equipment, may be the same for all, or may be changed under any condition. Moreover, the range may not be a simple circle, but may be a polygonal or complex shaped area set for each inspection target equipment.

[0070] In Figure 17, for the equipment i to be inspected, within the time range and within the circle of radius M, The position of the extracted worker w is expressed as L, where the order of detection time is k (1, 2, ... k). i,M,k The direction of the worker w at the position of the worker w is represented by φ i,M,k It is expressed as:

[0071] In FIG. 17, the worker position L is defined as a worker position within a predetermined time range (for example, ±10 minutes or -10 minutes) from the inspection result input time of the inspection target equipment i and within a distance M from the inspection target equipment i. i,M,1 , worker position L i,M,2 , worker position L i,M,3 Also, the position L of the worker w is extracted. i,M,k The orientation of the worker in each of (k=1~3) is the orientation of the worker φ i,M,1 , worker orientation φ i,M,2 (not shown), and the worker's orientation φ i,M,3 (not shown) is extracted.

[0072] In FC502, the position L of the worker w i,M,k For each of (k=1~3), the worker's position L i,M,k The direction to the equipment to be inspected i is calculated from the worker's position L i,M,k Let l be the line that passes through the inspection target equipment i. i,M,k The line is expressed as l i,M,kand the angle φ ´ i,M,k The position of worker w is L i,M,k In Fig. 17, the position φ of the worker w is calculated as the direction from the target equipment i to the target equipment i. i,M,1 from the direction of the inspection target equipment i, ´ i,M,1 is shown, and φ ´ i,M,2 and φ ´ i,M,3 The illustration is omitted.

[0073] In FC503, the position L of worker w is calculated using the calculation result of FC502. i,M,k For each of (k=1~3), the worker's orientation φ i,M,k and the direction φ ´ i,M,k The angle difference ω i,M,k That is, the angle difference ω i,M,k= |φ i,M,1― φ ´ i,M,1 Calculate |.

[0074] In FC504, the calculated angle difference ω i,M,k The smallest value of ω i is selected as shown in Equation 1 below.

[0075]

number

[0076] In this manner, as shown in steps FC501 to FC504, the positional relationship calculation unit 37a calculates, for each of a plurality of positions of the worker w within a predetermined time range from the inspection result input time, the angle difference between the orientation of the worker w at that position and the orientation from that position toward the equipment i to be inspected, and calculates the minimum value of the calculated angle differences as the value related to the positional relationship.

[0077] Next, a description will be given of the task evaluator 38a in Fig. 1. The task evaluator 38a evaluates whether the inspection task has been performed correctly, based on the value relating to the positional relationship calculated by the positional relationship calculator 37a.

[0078] FIG. 18 illustrates a flow of the evaluation performed by the task evaluator 38a. In FC701, the task evaluation unit 38a acquires values ​​related to the positional relationship calculated by the positional relationship calculation unit 37a. For example, the task evaluation unit 38a acquires values ​​related to the positional relationship of the above-mentioned (1) and (2) calculated by the positional relationship calculation unit 37a. In FC702, the work evaluation unit 38a evaluates whether or not at least one of the values ​​related to the positional relationship in (1) and (2) is within a predetermined range. If it is within the range, the work evaluation unit 38a evaluates that the inspection has been performed correctly, and if it is outside the range, the work evaluation unit 38a evaluates that the inspection has been performed incorrectly.

[0079] In detail, the task evaluation unit 38a evaluates the distance D i When this distance D i If this distance is within the predetermined range γ, the inspection is deemed to have been performed correctly. i If it is outside the range γ, it is evaluated that the inspection has not been performed correctly.

[0080] In addition, the task evaluation unit 38a evaluates the positional relationship in (2) by determining the angle difference ω i When this angle difference ω i If it is within a predetermined range θ, the inspection is evaluated as having been performed correctly, and if it is outside the range θ, the inspection is evaluated as having been performed incorrectly.

[0081] Here, the work evaluation unit 38a evaluates that the inspection has been performed correctly if either of the values ​​related to the positional relationship of (1) and (2) described above is within a predetermined range, but it may be configured to evaluate that the inspection has been performed correctly when both values ​​related to the positional relationship are within a predetermined range. i and the angle difference ω iIf at least one of the above is outside the range, it may be determined that the inspection has not been performed correctly. This allows a strict evaluation of whether the inspection has been performed correctly.

[0082] Moreover, the task evaluation unit 38a may use the value related to the positional relationship described above in (3) for the evaluation, instead of the value related to the positional relationship described above in (2). The result display unit 39a in Fig. 1 displays the evaluation result obtained by the task evaluation unit 38a in this manner.

[0083] In this manner, in this embodiment, the inspection work position of the worker w is calculated from the position of the worker w detected by the position detection terminal at each of multiple times and the time when the inspection result was input by the worker w to the operation terminal 2a, a value relating to the positional relationship between the inspection work position and the position of the equipment to be inspected is calculated, and it is evaluated from the calculation result whether the inspection was performed correctly. Therefore, it is possible to evaluate whether the inspection was performed correctly without having to install a device that sends a work completion signal near the equipment to be inspected, as in the conventional method.

[0084] In this embodiment, a device for sending a work completion signal may be installed near the equipment to be inspected as in the conventional case, and the work evaluation unit 38a may perform the above evaluation using a record of whether or not the work completion signal has been received. In that case, if the device for sending the work completion signal breaks down, it may be possible to evaluate whether the inspection was performed correctly without using the record of whether or not the signal has been received.

[0085] Embodiment 2 The difference between the first and second embodiments is that when evaluating whether the inspection has been performed correctly, the time that the worker w remains within a predetermined distance from the equipment to be inspected is also used. In the following, only the differences from the first embodiment will be described, and explanations of the same or corresponding parts will be omitted. Regarding the reference numerals, the same reference numerals will be used for the same or corresponding parts as the first embodiment, and explanations will be omitted.

[0086] In this embodiment, the positional relationship calculation unit 37a in FIG. 1 calculates the following (4) as a value related to the positional relationship, in addition to the values ​​related to the positional relationship of (1) and (2) or (3) described above in the first embodiment. (4) The time that the worker w remains within a predetermined distance range centered on the equipment to be inspected.

[0087] Fig. 19 is an example of a diagram in which the position of the worker w within a range of a predetermined distance N centered on the equipment i to be inspected is plotted in white. The black plots indicate the positions of the worker w outside that range. Fig. 20 shows the flow of calculating the residence time in (4) above.

[0088] In step FC701 of FIG. 20, the number p of positions of workers w within a range of a predetermined radius N centered on the inspection target equipment i is calculated. i,N In this embodiment, as shown in FIG. i,N =6.

[0089] In step FC702, the residence time of the worker w within the range of the radius N is calculated. The detection interval of the position of the worker w is Δt, and the residence time is t i The residence time is expressed as t i t i= p i,N × Δt. In this embodiment, p i,N = 6, the detection interval Δt = 1 second, so the residence time t i = 6 × 1 second = 6 seconds. In other words, 6 seconds is calculated as the value related to the positional relationship in (4) above.

[0090] The work evaluation unit 38a calculates the value of the positional relationship (4) above in addition to the evaluation based on the values ​​of the positional relationship (1) to (3) above, and evaluates that the inspection has been performed correctly if the value of the positional relationship (4) is equal to or greater than a predetermined reference value. In other words, the work evaluation unit 38a evaluates that the inspection has not been performed correctly if the residence time is shorter than the reference value. The work evaluation unit 38a may evaluate that the inspection has been performed correctly if any of the values ​​of the positional relationship (1) to (4) above is within a predetermined range, or may evaluate that the inspection has been performed correctly if all of (1) to (4) are within a predetermined range.

[0091] In this embodiment, the residence time (4) is calculated as a value related to the positional relationship, and whether the inspection work has been performed correctly is evaluated based on that residence time, making it possible to rigorously evaluate whether the inspection work has been performed correctly.

[0092] Embodiment 3 The present embodiment differs from the first and second embodiments in that at least one of still images or video images taken during the inspection of the equipment to be inspected is recorded, and the records are also used to evaluate whether the inspection work was performed correctly. In the following, only the differences from the first and second embodiments will be described, and explanations of the same or corresponding parts will be omitted. Regarding the symbols, the same symbols will be used for the same or corresponding parts as the first and second embodiments, and explanations will be omitted.

[0093] Fig. 21 is a functional block diagram of a patrol inspection work evaluation system 500c according to this embodiment. In this embodiment, as shown in Fig. 21, the operation terminal 2c further includes a photographing unit 24c and an image information storage unit 25c in addition to the configuration of the operation terminal 2a in Fig. 1. Also, the patrol inspection work evaluation device 3c further includes an image information storage unit 40a and a photographing work evaluation unit 41a in addition to the configuration of the patrol inspection work evaluation device 3a in Fig. 1.

[0094] The photographing unit 24c is provided with a lens (not shown) on the housing of the operation terminal 2c, and has a function of photographing at least one of still images and video. The worker w inputs the inspection results of the equipment to be inspected into the inspection record input unit 20a, and photographs the equipment to be inspected by the photographing unit 24c. A so-called shutter button for operating the photographing unit 24c is provided on the screen 300 for inputting the inspection results shown in FIG. 7 (not shown), for example.

[0095] The image information accumulation unit 25c stores the image of the inspection target equipment captured by the photographing unit 24c as inspection target equipment image information in association with the inspection result input to the screen 300. More specifically, the inspection target equipment image information stored in the image information accumulation unit 25c is composed of the name / ID of the inspection target equipment, at least one of a still image or a video image of the inspection target equipment captured by the photographing unit 24c, and the time of capture.

[0096] The image information of the inspection target equipment stored in the image information accumulation unit 25c is stored in the image information memory unit 40c of the patrol inspection work evaluation device 3c via the communication unit 23a of the operation terminal 2c and the communication unit 30a of the patrol inspection work evaluation device 3c.

[0097] The photographing work evaluation unit 41c evaluates whether the worker w was near the inspection target equipment when he / she input the inspection record, based on the inspection target equipment image information stored in the image information storage unit 40c. Fig. 22 shows the flow of the evaluation in the photographing work evaluation unit 41c.

[0098] In step FC901, the photography work evaluation unit 41c acquires the photography time of the image from the inspection target equipment image information stored in the image information storage unit 40c.

[0099] In step FC902, the photography work evaluation unit 41c extracts the position of the worker w at the photography time acquired in step FC901 from the position detection information stored in the position detection information storage unit 32a as the photography position of the worker w. If the position of the worker w at the time that coincides with the photography time is not included in the position detection information, the position of the worker w at the time closest to the photography time is extracted as the photography position. Alternatively, the position of the worker w at the time closest to the photography time may be extracted as the photography position.

[0100] In step FC903, it is evaluated whether the photographing position of the worker w is within a range of a predetermined distance z from the inspection target equipment. If it is within the range of distance z, it is evaluated that the worker w performed the inspection work correctly. If it is outside the distance z, it is evaluated that the worker w performed the inspection work incorrectly. The photographing work evaluation unit 41c displays the evaluation result on the result display unit 39a. That is, the result display unit 39a displays the evaluation result by the photographing work evaluation unit together with the evaluation result by the work evaluation unit 38a. Furthermore, the result display unit 39a extracts and displays the image at the photographing time used in the evaluation from the inspection target equipment image information stored in the image information storage unit 40c.

[0101] The operation terminal 2c may further have a function of displaying still images or videos of the equipment to be inspected taken in the past from the image information of the equipment to be inspected stored in the image information storage unit 25c. This allows the inspection to be performed while comparing the images or videos displayed by the display function and evaluating the current situation compared to the previous situation. As a result, the inspection can be performed with higher accuracy. In addition, the previously captured image may be displayed as a transparent image on the shooting screen displayed when shooting, allowing the image to be captured in an overlapping manner. As a result, the equipment to be inspected can be photographed at the same angle as when it was photographed previously.

[0102] In this embodiment, workers can leave at least one still image or video of the condition of the equipment being inspected as evidence of the patrol inspection work, and it is possible to more precisely evaluate whether the patrol inspection work was performed correctly from the shooting position.
