Description

[Technical field]

[0001] The present invention relates to a patrol inspection management system and a patrol inspection management program, and more particularly to a technique for checking whether a patrol inspection is being performed appropriately. [Background technology]

[0002] In power plants, etc., patrol inspections are conducted daily, weekly, monthly, etc., for the maintenance management of buildings and equipment. In these patrol inspections, the inspection points of the buildings and equipment are visually checked and the numerical values ​​and operations are checked to determine whether they are in an appropriate state. In such patrol inspection work, when there are many inspection points and inspection points, there is a possibility that inspection of the inspection points or inspection points may be skipped due to mistake or intention (such as skipping inspection of a certain inspection point or inspection point and inspecting the next inspection point or inspection point, or terminating the patrol inspection). If such an inspection point is skipped, not only may the safety of the buildings and equipment be compromised, but if the buildings and equipment are public or social infrastructure, it may have an external impact and become a compliance issue.

[0003] In the past, checklists and reports to superiors after patrol inspections have been used to check whether inspections are being carried out properly. However, with checklists, there is a possibility of mistakes occurring in the process of checking the list itself (forgetting to check something, checking the wrong list, etc.). In addition, reports to superiors are secondary information (as opposed to primary information obtained by confirming the inspection work on-site), so it is not easy to detect false reports such as falsification of the content.

[0004] Patent Document 1 discloses a maintenance management method and a maintenance management system for managing patrol inspection work. In the technology described in Patent Document 1, regarding the maintenance inspection of a computer delivered to a customer, location information and time information are sent from a mobile terminal carried by an inspection worker to a management server. Based on the information received from the mobile terminal, the management server determines whether the inspection worker is qualified to maintain the device to be maintained and whether the current location matches the location of the device to be maintained. The management server also determines that maintenance inspection has been performed based on confirmation by the customer that the inspection has been completed or whether a test program can be executed.

[0005] [Patent Document 1] JP 2008-204407 A Summary of the Invention [Problem to be solved by the invention]

[0006] However, the technology disclosed in Patent Document 1 requires confirmation of completion by a person other than the inspection worker or by a system, such as confirmation of completion by the customer or confirmation of execution of a test program, and cannot be applied to patrol inspections of unmanned inspection targets without a manager or inspection targets that do not require the execution of a test program.

[0011] The invention of claim 3 is characterized in that, in the patrol inspection management system described in claim 1 or 2, the storage device stores an average value of the actual inspection work time required by the worker for the inspection work and an average value of the actual additional work time required by the worker for the additional work, and the management device is equipped with an information management means that notifies a user when a difference between the average value of the actual inspection work time and the standard inspection work time is equal to or greater than a predetermined threshold value, or when a difference between the average value of the actual additional work time and the standard additional work time is equal to or greater than the threshold value.

[0012] The invention of claim 4 is characterized in that, in the patrol inspection management system described in any one of claims 1 to 3, the management device reports the fact when the judgment means judges that the patrol inspection of the inspection target has not been performed appropriately.

[0013] The invention of claim 5 is characterized in that, in the patrol inspection management system according to any one of claims 1 to 4, the required time calculation means calculates the predicted value of the required time using a first trained model that is machine-learned based on actual data of the predicted value of the required time obtained in a past patrol inspection and actual data of the additional work prediction information, the work time information, the worker information and the map information used to calculate the actual data of the predicted value of the required time.

[0014] The invention of claim 6 is characterized in that, in the patrol inspection management system described in any one of claims 1 to 5, the judgment means judges whether or not the patrol inspection of the inspection target has been performed appropriately using a second trained model machine-learned based on actual data of judgment results obtained in past patrol inspections and actual data of the judgment information used to obtain the actual data of the judgment results.

[0015] The invention of claim 7 is a patrol inspection management program for managing the patrol inspection of an inspection object, comprising a computer, a storage device for storing additional work prediction information indicating a prediction as to whether or not additional work other than inspection work will occur at the inspection object, work time information indicating a standard inspection work time of the inspection object and a standard additional work time for the additional work, and worker information indicating a movement speed and skill level of a worker performing the patrol inspection, and a calculation of a predicted value of a movement time required for the patrol inspection by the worker based on map information indicating a position of the inspection object and the movement speed of the worker, and a calculation of a predicted value of a movement time required for the patrol inspection by the worker based on the additional work prediction information, the standard inspection work time, and the standard additional work time. a required time calculation means for calculating a predicted value of a total work time required for the inspection work and additional work of the inspection object, correcting the calculated predicted value of the total work time based on the skill level of the worker, and adding the corrected predicted value of the total work time and the predicted value of the travel time to calculate a predicted value of the time required for the inspection of the inspection object; and a determination means for comparing the predicted value of the required time with an actual value of the required time, and determining whether the inspection of the inspection object has been performed appropriately based on determination information including a comparison result between the predicted value of the required time and the actual value of the required time. Effect of the Invention

[0016] According to the inventions described in claims 1 and 7, a predicted value of the time required for the visual inspection is calculated based on the predicted value of the travel time required for the visual inspection, the predicted value of the total work time required for the visual inspection, and the skill level of the worker, and based on the result of comparing this predicted value of the required time with the actual measured value of the required time, it is judged whether the visual inspection of the inspection target has been performed appropriately, so it is possible to confirm the suitability of the visual inspection for the inspection target in various situations. In addition, since it is not affected by the mistakes of the worker as in the case of a checklist, and is not affected by false reports from the worker, it is possible to more appropriately judge the suitability of the visual inspection.

[0017] According to the invention described in claim 2, the actual route traveled by the worker is compared with the predicted route used to calculate the predicted travel time, the position and time the worker stayed on the actual route are compared with the position of the inspection target and the predicted total work time at the inspection target, and based on the results of these comparisons, it is determined whether the inspection of the inspection target was performed appropriately. Therefore, it is possible to confirm how the worker actually moved and performed the inspection work based on the position information, etc., and it is possible to determine the appropriateness of the inspection, which cannot be determined simply by comparing the predicted and actual times required.

[0018] According to the invention described in claim 3, when the standard inspection work time or the standard additional work time used to calculate the predicted value of the required time for the patrol inspection is a value that does not match the actual work time, a notification to that effect is provided. Therefore, the standard inspection work time or the standard additional work time can be reviewed at an appropriate time, and the appropriateness of the patrol inspection can be appropriately determined.

[0019] According to the invention described in claim 4, when it is determined that the patrol inspection has not been performed appropriately, the fact is notified, so that an inappropriate patrol inspection will not be overlooked and left unattended. Therefore, it becomes an opportunity to redo the patrol inspection or to improve the operation of the patrol inspection, so that it becomes possible to appropriately judge whether the patrol inspection is appropriate or not.

[0020] According to the invention described in claim 5, the first trained model that has been machine-learned is used to calculate the predicted value of the time required for the patrol inspection, so that a more realistic predicted value of the time required that reflects the actual data of past patrol inspections can be obtained, making it possible to more appropriately judge whether or not a patrol inspection is appropriate.

[0021] According to the invention described in claim 6, a second trained model that has been machine-learned is used to judge whether a patrol inspection is appropriate or not, so that a more realistic judgment of appropriateness can be made that reflects the actual data of past patrol inspections, making it possible to more appropriately judge whether a patrol inspection is appropriate or not.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0023] Hereinafter, the present invention will be described based on the illustrated embodiment.

[0024] 1 is a block diagram showing a schematic configuration of a patrol inspection management system 1 according to an embodiment of the present invention. The patrol inspection management system 1 of the present embodiment is a system for instructing workers to carry out patrol inspection work on inspection targets such as buildings and equipment, and for determining whether the patrol inspection by the workers has been carried out appropriately.

[0025] The patrol inspection management system 1 is composed of a patrol inspection management server (management device) 2, a map information database (map information) 3, a mobile terminal (position detection device) 4 carried by a worker M who performs the patrol inspection, a worker terminal 5 used by the worker M, and a manager terminal 6 used by a manager of the patrol inspection work. The worker terminal 5 and the manager terminal 6 are typically a personal computer, a tablet terminal, a smartphone, or the like.

[0026] The patrol inspection management server 2, the worker terminal 5, and the manager terminal 6 are installed in the business establishment where the patrol inspection work is performed, and are connected via various wireless / wired communication networks such as a LAN (Local Area Network) so as to be able to transmit and receive signals and information to and from each other. The mobile terminal 4 is, for example, a wristwatch-type wearable terminal, and is connected via various wireless communication line networks so as to be able to transmit and receive signals and information to and from the patrol inspection management server 2.

[0027] The map information database 3 stores map information indicating the positions of buildings, various facilities, roads, etc. In the map information of the map information database 3 of this embodiment, the positions of facilities A, B, C, and D to be subject to patrol inspection and the position of the business office that serves as the base of the patrol inspection work are registered, and information regarding the roads connecting each of the facilities A to D with the business office is shown. The map information database 3 may be newly installed for this system, or a map information providing service such as Google Maps (registered trademark) may be used.

[0028] The patrol inspection management server 2 includes a patrol inspection database (storage device) 232 in which various information related to the patrol inspection work is stored. The patrol inspection management server 2 creates a patrol inspection work instruction sheet 7 for instructing the worker M to perform a patrol inspection, based on various information stored in the patrol inspection database (hereinafter also referred to as DB) 232 and map information acquired from the map information database 3.

[0029] The inspection work instruction 7 includes the "scheduled date" of the inspection, the "inspection course" indicating the equipment to be inspected, the "inspector" indicating the worker who will perform the inspection, and the predicted "required time" required for the inspection. The "inspection course" includes the name of the inspection course (e.g., B) and the name of the equipment to be inspected in the inspection course (e.g., equipment A, B, C). The "inspector" includes the name of the worker (e.g., W) and a skill correction value (e.g., ±0%) for correcting the work time according to the skill level of the worker M. The "required time" includes the predicted time required for the inspection (e.g., 95 minutes) and the predicted occurrence of additional work other than the inspection work (e.g., repair work for repairs, part replacement work, etc.) in the equipment to be inspected (e.g., repairs are expected to be performed on equipment A and C).

[0030] The time required for a patrol inspection is the time required for worker M to leave the starting point (business establishment), arrive at at least one facility or building, complete the inspection of the facility (including repairs or part replacement), and arrive at the return point (business establishment). For example, in the case of patrol inspection course B of the patrol inspection work instruction 7 shown in the figure, the time required for the patrol inspection is the time required to leave the business establishment, perform a patrol inspection of facilities A, B, and C, and return to the business establishment. The patrol inspection work instruction 7 is handed over in print to worker M who will be the inspector, or the created data is sent to the worker terminal 5 or mobile terminal 4 of the inspector.

[0031] The worker M who has become the inspector wears the mobile terminal 4 and performs a patrol inspection of the equipment based on the patrol inspection work instruction 7. For example, when performing a patrol inspection according to the patrol inspection course B (equipment A, B, C) of the patrol inspection work instruction 7 shown in the figure, the worker M leaves the business premises, performs a patrol inspection of equipment A, B, C, and returns to the business premises. The mobile terminal 4 has a function of detecting position information based on a global navigation satellite system (GNSS) such as a global positioning system (GPS). During the patrol inspection by the worker M, the mobile terminal 4 detects the position information of the worker M at a predetermined time interval and transmits the detected position information together with the detection time to the patrol inspection management server 2.

[0032] After completing the patrol inspection and returning to the business premises, worker M creates a patrol inspection work report 8 using worker terminal 5 and transmits the data to the patrol inspection management server 2. The patrol inspection work report 8 includes the actual measurement value of the time required for the patrol inspection (e.g., 80 minutes), the name of the equipment for which additional work occurred, and the details of the additional work (e.g., equipment A (repair), equipment C (repair)).

[0033] The patrol inspection management server 2 compares the actual value of the required time for the patrol inspection calculated from the position information and time information received from the mobile terminal 4 with the predicted value of the required time for the patrol inspection described in the patrol inspection work instruction 7, and judges whether the patrol inspection was performed appropriately based on judgment information including the comparison result. Note that the required time for the patrol inspection described in the patrol inspection work report 8 may be used as the actual value of the required time for the patrol inspection. If the patrol inspection management server 2 judges that the patrol inspection by the worker M was not performed appropriately, it notifies the administrator terminal 6 by sending an alert indicating that fact.

[0034] 2 is a functional block diagram showing a schematic configuration of the patrol inspection management server 2. The patrol inspection management server 2 mainly includes an input unit 21, a display unit 22, a storage unit 23, a memory 24, a main task 25, a communication unit 26, and a central processing unit 27 that controls these units. The patrol inspection management server 2 is configured, for example, by installing a control program for the entire device and an application (patrol inspection management program 231) that performs various processes for managing the patrol inspection on a personal computer or the like.

[0035] The input unit 21 is an interface having a function of receiving commands from a user and inputting information to the patrol inspection management server 2, and is configured, for example, by a keyboard and a mouse. The display unit 22 is configured, for example, by a liquid crystal display. The display unit 22 displays information input via the input unit 21, displays the created patrol inspection work instructions 7 and the received patrol inspection work reports 8, and displays the judgment results of the patrol inspection.

[0036] The storage unit 23 is a storage area / storage device having a function of storing various information, programs, data, and the like, and is configured by, for example, a hard disk. The storage unit 23 stores a control program for controlling the entire patrol inspection management server 2, a patrol inspection management program 231, and the like. The storage unit 23 also stores the above-mentioned patrol inspection database 232, a trained model for required time calculation 233 for calculating a predicted value of the required time for the patrol inspection, a trained model for judgment 234 for judging whether the patrol inspection has been performed appropriately, and a performance database 235. The performance database 235 stores performance data that serves as teacher data for machine learning the trained model for required time calculation 233 and the trained model for judgment 234.

[0037] The memory 24 is a storage area / storage device having a function of serving as a working area for temporarily storing information and data generated when the central processing unit 27 executes various processes for managing the patrol inspection, and is configured, for example, by a RAM.

[0038] The main task 25 is a group of tasks that execute various processes for managing the patrol inspection, which are realized by the central processing unit 27 executing the patrol inspection management program 231 stored in the memory unit 23.

[0039] The communication unit 26 is a communication interface having a function of transmitting / receiving / inputting / outputting signals and information transmitted via a communication network.

[0040] The central processing unit 27 has the function of comprehensively controlling each part that constitutes the patrol inspection management server 2, and is configured to include a central processing unit such as a CPU, and realizes each function in accordance with the control program and the patrol inspection management program 231 stored in the memory unit 23.

[0041] The patrol inspection database 232 stores a patrol performance management table 2311, an equipment inspection work management table 2312, a worker management table 2313, and a patrol inspection course table 2314, as shown in Figures 3(A) and (B) and Figures 4(A) and (B).

[0042] The inspection record management table 2311 registers the inspection frequency (e.g., daily, weekly, monthly, etc.) and the next inspection date for the equipment A, B, C, and D that are the subject of the inspection. The inspection record management table 2311 registers the average value of the repair work frequency (e.g., once / twice inspection, etc.) for the equipment A, B, C, and D, the results of the previous repair work (e.g., two times ago, etc.), and a prediction of the next repair work (e.g., "yes" or "no"). Furthermore, the inspection record management table 2311 registers the average value of the part replacement work frequency for the equipment A, B, C, and D, the results of the previous replacement work, and a prediction of the next replacement work. The prediction of the next repair work and the prediction of the next replacement work correspond to additional work prediction information of the present invention.

[0043] The equipment inspection work management table 2312 registers standard work times for equipment A, B, C, and D that are the subject of inspection patrols, and average work times indicating the average of the results of work times. The standard work time indicates, for example, the work time of a worker M with a standard skill level, and the average work time is the average of the actual measured time when workers M with different skill levels perform the same work. The standard work time registers the standard inspection time required for inspection work, the standard repair time required for repair work, and the standard part replacement time required for part replacement work. The average work time registers the average inspection time required for inspection work, the average repair time required for repair work, and the average part replacement time required for part replacement work. The results of the work times required for the inspection work, repair work, and part replacement work of the worker M are identified based on the location information and time information transmitted from the mobile terminal 4.

[0044] The standard inspection time corresponds to the standard inspection work time in the work time information of the present invention, and the standard repair time and standard part replacement time correspond to the standard additional work time in the present invention. The average inspection time corresponds to the average value of the actual inspection work time in the present invention, and the average repair time and average part replacement time correspond to the average value of the actual additional work time in the present invention. The average inspection time, average repair time, and average part replacement time are updated every time a patrol inspection is performed, and are used to review the standard inspection time, standard repair time, and standard part replacement time.

[0045] The worker management table 2313 registers the average movement speed (e.g., walking speed) of workers W, X, Y, and Z who are workers M, their skill levels, and the equipment they can inspect. The skill levels are S, A, B, C, and D from top to bottom, and the types of equipment they can inspect vary depending on the skill level. In other words, a worker M with a high skill level can inspect more types of equipment than a worker M with a low skill level.

[0046] The standard work time of worker M is corrected according to the skill level. For example, for standard skill level B, the skill correction for work time is ±0%. For S and A, whose skill levels are higher than B, the skill corrections are -20% and -10%, respectively. For C and D, whose skill levels are lower than B, the skill corrections are +10% and +20%, respectively. In other words, when performing an inspection task with a standard inspection time of 10 minutes, the standard inspection time of worker M with skill level B is 10 minutes without any correction. In contrast, the standard inspection time of worker M with skill level B is corrected by -20% to 8 minutes. Furthermore, the standard inspection time of worker M with skill level D is corrected by +20% to 12 minutes.

[0047] In the inspection course table 2314, the course name, the inspection frequency, and the name of the equipment to be inspected are registered. For example, the equipment to be inspected in inspection course A is equipment A and B, and the inspection frequency is "everyday" which is common to equipment A and B. Also, the equipment to be inspected in inspection course B is equipment A, B, and C, and the inspection frequency is "every week" which is the lowest frequency for equipment A, B, and C. In other words, when equipment with different inspection frequencies is set in the same inspection course, the lowest inspection frequency of each piece of equipment becomes the inspection frequency for the inspection course.

[0048] As described above, the patrol inspection management server 2 creates the patrol inspection work instruction 7 based on the information stored in the patrol inspection database 232, has the worker M perform the patrol inspection, judges whether the patrol inspection has been performed appropriately, and sends an alert if the patrol inspection has not been performed. In addition, an alert is also sent when it becomes necessary to review the standard work time. These processes are performed by the main task 25, which is configured by executing the patrol inspection management program 231 stored in the storage unit 23. The main task 25 includes an instruction creation task 251, a required time calculation task (required time calculation means) 252, a judgment task (judgment means) 253, a notification task 254, an information management task (information management means) 255, and a learning task 256.

[0049] The instruction creation task 251 creates the patrol inspection work instruction 7 according to the patrol inspection frequency in the patrol inspection course table 2314 stored in the patrol inspection database 232. That is, for the patrol inspection course A, the patrol inspection work instruction 7 is created daily, and for the patrol inspection courses B and C, the patrol inspection work instruction 7 is created weekly and monthly. The instruction creation task 251 refers to, for example, schedule data (not shown) in which the schedule of the worker M is registered via a communication network, sets the worker M who is free on the scheduled date of the inspection and has a skill level capable of inspection as the inspector, and creates the patrol inspection work instruction 7. The instruction creation task 251 also refers to the next repair work and the next replacement work in the patrol inspection result management table 2311 stored in the patrol inspection database 232, confirms the prediction of the repair work or replacement work, and records it in the patrol inspection work instruction 7.

[0050] The required time calculation task 252 calculates a predicted value of the required time to be described in the patrol inspection work instruction 7 created in the instruction creation task 251. Specifically, the required time calculation task 252 sets a predicted moving route from the business establishment, patrols the equipment set in the patrol inspection course, and returns to the business establishment based on the map information of the map information database 3, identifies the distance of this predicted moving route from the map information, and calculates a predicted value of the moving time by dividing the distance of the predicted moving route by the moving speed of the inspector. The predicted moving route is set, for example, to be the shortest distance in the map information. Note that, when the inspection sequence of multiple pieces of equipment is determined, the predicted moving route is specified to be the shortest distance according to the inspection sequence. For example, in the case of the patrol inspection course B shown in FIG. 1, the route from the business establishment to equipment B, moving from equipment B to equipment A to equipment C, and returning from equipment C to the business establishment is the shortest distance, so this route is set as the predicted moving route. If this predicted route is, for example, 2.7 km, the predicted travel time for inspector W, whose average travel speed is 4 km / h, is approximately 40 minutes.

[0051] Next, the required time calculation task 252 calculates a predicted value of the total work time required for the inspection work and additional work for each piece of equipment based on the next repair work and the next replacement work registered in the inspection record management table 2311 of the inspection database 232 and the standard inspection time, standard repair time, and standard part replacement time registered in the equipment inspection work management table 2312. For example, in the case of the inspection course B shown in FIG. 1, since repair work is expected for equipment A and C, the predicted value of the total work time for equipment A is the sum of the standard inspection time (10 minutes) and the standard repair time (10 minutes). In addition, the predicted value of the total work time for equipment B is the standard inspection time (20 minutes) because there is no additional work. The predicted value of the total work time for equipment C is the sum of the standard inspection time (10 minutes) and the standard repair time (5 minutes). The predicted value of the work time for the entire inspection course B is the sum of these total work times (55 minutes).

[0052] The required time calculation task 252 applies a skill correction to the calculated total work time for the entire patrol inspection course B based on the skill level of the inspector registered in the worker management table 2313 of the patrol inspection database 232. For example, in the case of the patrol inspection work instruction 7 shown in FIG. 1, the skill correction of inspector W is ±0%, so the predicted total work time of 55 minutes remains unchanged. If the inspector is Z, the skill level is S, so the predicted total work time for the entire patrol inspection course B is corrected to -20%, or 44 minutes. If the inspector is X, the skill level is C, so the predicted total work time for the entire patrol inspection course B is corrected to +10%, or 60.5 minutes.

[0053] The required time calculation task 252 calculates the predicted value of the required time for the patrol inspection by adding the predicted value of the total work time of the entire patrol inspection course B corrected according to the skill correction to the predicted value of the travel time. For example, in the case of the patrol inspection work instruction 7 shown in Fig. 1, the predicted value of the travel time of 40 minutes is added to the predicted value of the total work time of the entire patrol inspection course B of 55 minutes, and the predicted value of the required time is 95 minutes.

[0054] The required time calculation task 252 uses a trained model for required time calculation (first trained model) 233 to calculate a predicted value of the required time for the above-mentioned patrol inspection. The trained model for required time calculation 233 is created by a learning task 256. The learning task 256 creates the trained model for required time calculation 233 by a known machine learning / deep learning algorithm such as a neural network, using performance data of the predicted value of the required time obtained in a past patrol inspection recorded and accumulated in a performance database 235 stored in the storage unit 23, a patrol performance management table 2311 used to calculate the performance data of the predicted value of the required time, an equipment inspection work management table 2312, a worker management table 2313, and performance data of map information.

[0055] The judgment task 253 compares the predicted value of the required time calculated by the required time calculation task 252 with the actual measured value of the required time, and judges whether the patrol inspection has been performed appropriately based on judgment information (see FIG. 5) including the comparison result. Specifically, the judgment task 253 obtains the difference between the predicted value of the required time and the actual measured value of the required time, and judges that the patrol inspection has not been performed appropriately if this difference is large. A case where the difference between the predicted value of the required time and the actual measured value of the required time is large refers to, for example, a case where there is a difference equivalent to the standard inspection time, standard repair time, or standard part replacement time of a certain piece of equipment included in the patrol inspection course. In this case, the judgment task 253 presumes that the inspection work or additional work for the equipment was not performed, and judges that the patrol inspection has not been performed appropriately. For example, in the case of the patrol inspection shown in Figure 1, the predicted time required is 95 minutes, while the actual time required recorded in the patrol inspection work report 8 is 80 minutes. Therefore, it is presumed that the inspection and repair work for equipment C equivalent to the difference of 15 minutes was not performed, and it is determined that the patrol inspection was not performed appropriately.

[0056] The judgment task 253 uses the trained model for judgment (second trained model) 234 to judge whether the above-mentioned visual inspection was appropriate or not. The trained model for judgment 234 is created by a learning task 256. The learning task 256 creates the trained model for judgment 234 by a known machine learning / deep learning algorithm such as a neural network, using performance data of judgment results obtained in past visual inspections recorded and accumulated in a performance database 235 stored in the storage unit 23 and performance data of judgment information used to obtain the performance data of the judgment results.

[0057] When the judgment task 253 judges that the patrol inspection was not performed appropriately, the notification task 254 transmits an alert indicating that to the manager terminal 6. This alert indicates not only the judgment result but also the reason for the judgment. For example, in the case of the patrol inspection shown in FIG. 1, the alert is transmitted together with a message such as "It is presumed that the inspection work and repair work for facility C were not performed." This enables the manager of the patrol inspection work to confirm whether the patrol inspection was inappropriate for the reason judged in the judgment task 253, or whether it was inappropriate for some other reason.

[0058] The information management task 255 transmits an alert to the manager terminal 6 to prompt a review of the standard inspection time, standard repair time, and standard part replacement time when the difference between the standard inspection time, standard repair time, and standard part replacement time registered in the equipment inspection work management table 2312 of the patrol inspection database 232 and the average inspection time, average repair time, and average part replacement time is equal to or greater than a preset threshold value. This makes it possible to determine whether the patrol inspection was performed appropriately based on the appropriately set standard inspection time, standard repair time, and standard part replacement time. As a threshold value for transmitting the alert, for example, an alert may be transmitted when the average inspection time, average repair time, and average part replacement time are greater than or equal to n% (n is an arbitrary numerical value) or smaller than the standard inspection time, standard repair time, and standard part replacement time.

[0059] Next, the operation of the above embodiment will be described. The instruction creation task 251 of the patrol inspection management server 2 starts operating at a predetermined time every day and creates the patrol inspection work instruction 7. The instruction creation task 251 refers to the patrol inspection frequency registered in the patrol inspection course table 2314 of the patrol inspection database 232, and identifies the patrol inspection course for which the patrol inspection work instruction 7 needs to be created. When the instruction creation task 251 identifies the patrol inspection course for which the patrol inspection work instruction 7 needs to be created, it refers to the schedule data in which the schedule of the worker M is registered, sets the worker M who is free on the scheduled date of the inspection and has a skill level capable of inspection as the inspector, and writes it in the patrol inspection work instruction 7. In addition, the instruction creation task 251 refers to the next repair work and the next replacement work registered in the patrol performance management table 2311 of the patrol inspection database 232, confirms the prediction of the repair work or replacement work, and writes it in the patrol inspection work instruction 7.

[0060] The required time calculation task 252 calculates a predicted value of the required time to be described in the patrol inspection work instruction 7 created in the instruction creation task 251. Based on the map information in the map information database 3, the required time calculation task 252 sets a predicted movement route from departing from the business establishment, patrolling the equipment set in the patrol inspection course, and returning to the business establishment, identifies the distance of this predicted movement route from the map information, and calculates a predicted value of the movement time by dividing the distance of the predicted movement route by the movement speed of the inspector. The predicted movement route is set, for example, to be the shortest distance in the map information.

[0061] The required time calculation task 252 calculates a predicted value of the total work time required for the inspection work and additional work of the inspection target based on the next repair work and next replacement work registered in the inspection result management table 2311 of the patrol inspection database 232 and the standard inspection time, standard repair time, and standard part replacement time registered in the equipment inspection work management table 2312. The required time calculation task 252 also performs skill correction on the calculated total work time based on the skill level of the inspector registered in the worker management table 2313 of the patrol inspection database 232. The required time calculation task 252 adds the predicted value of the skill-corrected total work time and the predicted value of the travel time to calculate a predicted value of the time required for the patrol inspection.

[0062] The instruction creation task 251 enters the predicted time required for the patrol inspection, calculated in the required time calculation task 252, into the patrol inspection work instruction 7, and transmits the created patrol inspection work instruction 7 to the person in charge of inspection.

[0063] The worker M who has become the inspector wears the portable terminal 4 and performs a patrol inspection of the equipment based on the patrol inspection work instruction sheet 7. The portable terminal 4 detects the location information of the worker M at a predetermined time interval during the patrol inspection by the worker M, and transmits the detected location information together with the detection time to the patrol inspection management server 2. The patrol inspection management server 2 identifies the actual work time required for the inspection work, repair work, and part replacement work of the worker M based on the location information and time information transmitted from the portable terminal 4, and updates the average inspection time, average repair time, and average part replacement time registered in the equipment inspection work management table 2312.

[0064] The judgment task 253 compares the predicted value of the required time calculated by the required time calculation task 252 with the actual measured value of the required time, and judges whether the visual inspection has been performed appropriately or not based on judgment information (see FIG. 5) including the comparison result. Specifically, the judgment task 253 calculates the difference between the predicted value of the required time and the actual measured value of the required time, and judges that the visual inspection has not been performed appropriately if this difference is large.

[0065] When the judgment task 253 judges that the patrol inspection has not been performed appropriately, the notification task 254 transmits an alert indicating that fact to the manager terminal 6. This alert indicates not only the judgment result but also the reason for the judgment.

[0066] The information management task 255 sends an alert to the administrator terminal 6 to prompt a review of the standard inspection time, standard repair time, and standard part replacement time when the difference between the standard inspection time, standard repair time, and standard part replacement time registered in the equipment inspection work management table 2312 of the patrol inspection database 232 and the average inspection time, average repair time, and average part replacement time is equal to or greater than a preset threshold value.

[0067] As described above, according to the patrol inspection management system 1 and the patrol inspection management program 231, the predicted time required for the patrol inspection is calculated based on the predicted travel time required for the patrol inspection, the predicted total work time required for the patrol inspection, and the skill level of the worker M, and based on the comparison result between the predicted time and the actual time, it is determined whether the patrol inspection of the inspection target has been performed appropriately, so it is possible to confirm the suitability of the patrol inspection for inspection targets in various situations. In addition, since it is not affected by the mistakes of the worker M as in the case of a checklist, and is not affected by false reports from the worker M, it is possible to more appropriately determine the suitability of the patrol inspection.

[0068] Furthermore, according to this patrol inspection management system 1 and patrol inspection management program 231, if the standard inspection time, standard repair time, and standard part replacement time used to calculate the predicted time required for a patrol inspection are values ​​that do not match the actual work time, a notification to that effect is sent to the administrator terminal 6. This enables the standard inspection time, standard repair time, and standard part replacement time to be reviewed at an appropriate time, making it possible to more appropriately determine whether or not a patrol inspection is appropriate.

[0069] Furthermore, according to the patrol inspection management system 1 and the patrol inspection management program 231, if it is determined that the patrol inspection has not been performed appropriately, the administrator terminal 6 is notified of this fact, so that an inappropriate patrol inspection will not be overlooked and left unattended. This provides an opportunity to redo the patrol inspection or revise the operation of the patrol inspection, making it possible to more appropriately determine whether the patrol inspection is appropriate.

[0070] In addition, according to this patrol inspection management system 1 and patrol inspection management program 231, a machine-learned trained model for calculating the required time 233 is used to calculate the predicted value of the required time for a patrol inspection, so that a more realistic predicted value of the required time that reflects the actual data of past patrol inspections can be obtained, making it possible to more appropriately judge the appropriateness of a patrol inspection.

[0071] Furthermore, according to this patrol inspection management system 1 and patrol inspection management program 231, a machine-learned trained model for judgment 234 is used to judge whether a patrol inspection is appropriate, so that a more realistic judgment of appropriateness can be made that reflects the actual data of past patrol inspections, making it possible to more appropriately judge whether a patrol inspection is appropriate.

[0072] In the above embodiment, the appropriateness of the visual inspection is judged based on the comparison result between the predicted value and the actual value of the time required for the visual inspection, but the position information of the worker M received from the mobile terminal 4 may be used for this judgment. More specifically, the judgment task 253 identifies the actual movement route actually traveled by the worker M, the stay position where the worker M stayed (meaning a state of not moving) on ​​this actual movement route, and the stay time at the stay position, based on the position information and time information received from the mobile terminal 4 and the map information of the map information database 3. Then, the judgment task 253 compares this actual movement route with the expected movement route used when calculating the predicted value of the movement time, compares the stay position and stay time with the position of each piece of equipment and the predicted value of the work time at that equipment, and judges whether the visual inspection was performed appropriately based on the judgment information (see FIG. 6) including these comparison results. That is, the judgment task 253 judges whether or not a patrol inspection is appropriate by comprehensively judging the results of comparison between the actual movement path and the predicted movement path, the residence position and residence time, the results of comparison between the position of each piece of equipment and the predicted value of the work time at that equipment, and the results of comparison between the predicted value of the required time and the actual measured value, thereby making it possible to more accurately judge whether or not a patrol inspection is appropriate.

[0073] When judging the appropriateness of a visual inspection using the actual movement path of worker M, etc., it can be determined that the visual inspection is not being performed appropriately if worker M deviates significantly from the expected movement path (for example, if he / she moves away from the expected movement path by more than a specified distance), if he / she stays at each piece of equipment longer than the required work time, if he / she stays in a place other than each piece of equipment for more than a specified time, or if worker M does not pass through each piece of equipment at the time he / she is expected to pass through it.

[0074] In addition, if worker M moves between facilities via a route different from the expected travel route, a new predicted value of the time required for the patrol inspection can be calculated based on the actual travel route of worker M, and this newly calculated predicted value of the time required can be compared with the actual measured value to determine whether or not the patrol inspection is appropriate.

[0075] This makes it possible to confirm how workers actually moved and performed inspection work based on their location information, etc., and to determine whether or not a patrol inspection was appropriate, which cannot be determined simply by comparing the predicted and actual times required.

[0076] In the above embodiment, an example has been described in which the patrol inspection database (storage device) 232 is provided in the patrol inspection management server (management device) 2, but the patrol inspection database 232 may be provided separately from the patrol inspection management server 2. In addition, although the GNSS is used to detect the position information of the worker M, a positioning technology using Bluetooth (registered trademark) may also be used. [Explanation of symbols]
