[0027] In order to make the objectives, technical solutions and advantages of the present application more clear, the embodiments of the present application will be further described in detail below with reference to the accompanying drawings.

[0028] It should be noted that the inspection route evaluation method provided in the present application is generally executed by a mobile terminal, and accordingly, the inspection route evaluation device is generally arranged in the mobile terminal.

[0029] The mobile terminal of the present application may also be equipped with a display device and a camera. The display device may be any device capable of realizing a display function, and the camera is used to collect video streams; for example, the display device may be a cathode ray tube display (CR), a light-emitting diode display (LED), an electronic ink screen, a liquid crystal display (LCD), a plasma display panel (PDP), etc. The user may use the display unit on the mobile terminal to view displayed text, pictures, videos and other information.

[0030] The following will be combined with the attached Figure 1 , the inspection route evaluation method provided in the embodiment of the present application is introduced in detail. Among them, the inspection route evaluation device in the embodiment of the present application can be a mobile terminal.

[0031] See also Figure 1, which is a flow chart of a method for evaluating an inspection route provided in an embodiment of the present application. Figure 1 As shown, the method of the embodiment of the present application may include the following steps:

[0032] S101. Obtain the number k of inspection tasks associated with a target inspection route.

[0033] The inspection route consists of multiple check-in points. The inspection personnel check in at each check-in point in a certain order. The check-in method can be: use the mobile terminal to scan the QR code set at the check-in point to check in or use the mobile terminal to read the RFID tag set at the check-in point to punch in. The user conducts k inspections on the target inspection route within a certain period of time to form k inspection tasks, that is, k represents the number of inspections of the target inspection route by the user. The mobile terminal stores the attribute information of each inspection task, which includes the actual number of steps, actual working hours, name of the inspector, name of the inspection route, etc.

[0034] S102: If the number k is greater than the number threshold, obtain the actual number of steps and actual working hours of each of the k inspection tasks.

[0035] Among them, the mobile terminal obtains the number k of inspection tasks formed by the user's inspection of the target inspection route, and determines whether k is within the quantity threshold. The quantity threshold can be determined according to actual needs, and this application does not impose any restrictions. For example: the quantity threshold is 30. When the number k of inspection tasks associated with the target inspection route is greater than 30, the actual number of steps and actual working hours of each of the k inspection tasks are obtained. The actual number of steps indicates the deployment taken by the user in the process of performing the inspection task. The actual number of steps can be counted using the built-in pedometer in the mobile terminal carried by the user. The actual working hours indicate the length of time the user spends in the process of performing the inspection task. The actual working hours can be counted using the timer of the mobile terminal carried by the user.

[0036] In one or more possible embodiments, see Figure 2 As shown, the actual number of steps and actual working hours of each inspection task in k inspection tasks are obtained, including:

[0037] S201. Count multiple check-in points included in the inspection task.

[0038] S202: Determine the current number of steps and the current time corresponding to each check-in point.

[0039] S203, calculating the actual number of steps and actual working hours of the inspection task according to the current number of steps and the current time corresponding to each check-in point.

[0040] For example, inspection route A includes 10 check-in points, which are arranged in order: check-in point A1 to check-in point A10; when the user scans the code to clock in at the check-in point, the mobile terminal records the current time and the current number of steps. The current time and the current number of steps recorded at each check-in point are shown in Table 1:

[0041] Check-in point A1 A2 … A9 A10 Current time stepa1 stepa2 … stepa9 stepa10 Current step count datea1 datea2 … datea9 datea10

[0042] Table 1

[0043] Then, according to the current time and current number of steps of each check-in point recorded in Table 1, the time difference and step difference of the check-in interval formed by two adjacent check-in points are calculated. For example, check-in point A1 and check-in point A2 form check-in interval A1A2, the step difference of the check-in interval is stepa2-stepa1, and the time difference is datea2-datea1. This application can determine whether the user has completed the check-in of all check-in points based on the number and location of the check-in points. As shown in Table 2:

[0044] Check-in interval A1A2 A2A3 … A9A10 Step Difference stepa2-stepa1 stepa3-stepa2 … stepa10-stepa9 Time difference datea2-datea1 datea3-datea2 … datea10-datea9

[0045] Table 2

[0046] The actual number of steps of the inspection task is obtained by summing up the step number differences of each check-in interval calculated in Table 2, and the actual working hours of the inspection task are obtained by summing up the time differences of each check-in interval.

[0047] In one or more possible embodiments, the target inspection route is one of multiple candidate inspection routes. If the number of inspection tasks associated with the target inspection route is less than or equal to a quantity threshold, the next target inspection route is selected from the multiple candidate inspection routes for evaluation until all inspection routes have completed the evaluation.

[0048] S103: Identify qualified inspection tasks among the k inspection tasks according to the actual number of steps and the actual working hours.

[0049] Among them, the number of qualified inspection tasks among the k inspection tasks may be multiple, and the qualified inspection tasks represent the inspection tasks whose actual number of steps and actual working hours fluctuate within a preset range.

[0050] In one or more possible embodiments, the step of identifying qualified inspection tasks among the k inspection tasks according to the actual number of steps and the actual working hours includes:

[0051] According to the formula Calculate the step deviation rate of the i-th inspection task:

[0052] According to the formula Calculate the man-hour deviation rate of the i-th inspection task;

[0053] If the step number deviation rate and the formula deviation rate are both less than or equal to the deviation threshold, the i-th inspection task is identified as a qualified inspection task.

[0054] Wherein, s represents the preset standard number of steps, z represents the preset standard working hours, and the deviation threshold is determined according to actual needs, and this application does not limit it. For example, if the deviation threshold is 50%, s=19000, z=60 minutes. According to the above method, all qualified inspection tasks are identified from k inspection tasks, and the number of all qualified inspection tasks is counted.

[0055] S104: If the proportion of qualified inspection tasks in the k inspection tasks is greater than a proportion threshold, calculate a quality evaluation value of the target inspection route.

[0056] Among them, the ratio threshold can be determined according to actual needs. For example, when the ratio threshold is 70%, then when k=30, determine whether the number of qualified inspection tasks among the 30 inspection tasks is greater than 21. If yes, calculate the quality evaluation value of the target inspection route. If not, select the next target inspection task from multiple candidate inspection routes for evaluation.

[0057] The quality assessment value of the target inspection route is calculated using the following formula:

[0058] Wherein, M is the quality evaluation value, w1 and w2 are weight values, w1+w2=1, i is the sequence number of the inspection task, m i Indicates the actual number of steps of the ith inspection task, n i represents the actual working time of the i-th inspection task, s represents the preset standard number of steps, and z represents the preset standard working time.

[0059] For example: k=30, w1=0.4, w2=0.6, s=19000 steps, z=60 minutes.

[0060] S105: If the quality assessment value is greater than the quality assessment threshold, it is determined that the target inspection route is reasonably set.

[0061] Among them, the quality assessment threshold can be determined according to actual needs. For example, the quality assessment threshold is 0.9. Assuming that the quality assessment value of the target inspection route according to S204 is 0.978, then 0.978>0.9, the target inspection route is reasonably set, and the target inspection route is moved to the preferred route list. For a reasonably set inspection route, the time or number of steps taken by different users to perform inspections or the same user to perform different inspections does not fluctuate much, and has good stability.

[0062] Further, according to the method of the present application, multiple candidate inspection routes are evaluated, all inspection routes that meet the requirements are moved into a preferred route list, and the preferred route list is displayed on a display unit.

[0063] Furthermore, before S101 of the present application, the following is further included:

[0064] Set the quantity threshold, ratio threshold, standard number of steps, standard working hours, and quality assessment threshold for the target inspection route.

[0065] Among them, different target inspection routes are set with different quantity thresholds, proportion thresholds, standard number of steps, standard working hours and quality assessment thresholds, and the corresponding values ​​can be set according to the length and location of the target inspection route.

[0066] The embodiment of the present application obtains multiple inspection tasks associated with the target inspection route, and when the number of inspection tasks is greater than a number threshold, identifies qualified inspection tasks from the multiple inspection tasks, and when the proportion of qualified inspection tasks is greater than a proportion threshold, calculates a quality assessment value based on the attribute values ​​of each inspection task. If the quality assessment value is greater than the quality assessment threshold, it is determined that the setting of the target inspection route is reasonable. The present application automatically evaluates the rationality of the attribute values ​​obtained based on multiple inspections of the target inspection route, thereby evaluating the rationality of the set inspection route, so as to identify and correct unreasonable inspection routes and improve the inspection work efficiency.
