[0012] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0013] Embodiment 1: Figure 1 As shown, the present invention proposes a public equipment operation and maintenance management system based on smart city, including an operation and maintenance management platform, an inspection allocation module, an inspection tracking module and an equipment comprehensive evaluation module, and the operation and maintenance management platform is communicatively connected with the inspection allocation module, the inspection tracking module and the equipment comprehensive evaluation module; the operation and maintenance management platform obtains the public equipment to be managed (mainly public power equipment), and marks the corresponding public equipment as i, i={1,2,…,n}, n represents the number of public equipment to be managed and n is a natural number greater than 1; The operation log of public equipment i is collected and it is determined whether there is an operation abnormality. When an operation abnormality occurs, the abnormality type is sent to the inspection and allocation module; the inspection and allocation module sets a screening area and obtains all the preliminary personnel, analyzes the preliminary personnel to obtain the corresponding inspection value, determines the allocation object based on the numerical value of the inspection value, and sends the location of public equipment i, the abnormality type and the most suitable travel path to the intelligent terminal of the allocation object. The allocation object promptly goes to the location of the corresponding public equipment i and handles the abnormality, so as to realize the rapid handling of the abnormalities related to the public equipment i; the specific operation process of the inspection and allocation module is as follows: A circle with a radius of R1 is drawn with the corresponding public equipment i as the center, and the circular area is marked as the screening area. The smart terminals of all inspection and maintenance personnel in the screening area are obtained, and an "on-the-job inquiry" command is sent to the smart terminals of the inspection and maintenance personnel. The inspection and maintenance personnel who feedback the "confirmed on-the-job" information within the inquiry response time are marked as preliminary personnel; the effectiveness value of the corresponding preliminary personnel and the inspection effectiveness value of the corresponding abnormal type of the corresponding public equipment are retrieved from the operation and maintenance management platform, and the distance between the corresponding preliminary personnel and the public equipment i is obtained and marked as the detection distance value, and the length of service of the corresponding preliminary personnel and the total number of times the corresponding abnormal type of the corresponding public equipment is processed are obtained; By formula The effectiveness value CX, inspection effectiveness value JZ, inspection distance value QJ, length of service GT and total number of processing times TY are normalized to obtain the inspection value JX; among them, a1, a2, a3, a4, a5 are preset proportional coefficients, and the values ​​of a1, a2, a3, a4, a5 are all greater than zero; and the larger the value of the inspection value JX, the more suitable the corresponding preliminary personnel is for the current inspection and maintenance operation; the preliminary personnel are sorted in descending order according to the value of the inspection value, and the preliminary mark at the first place is the allocation object.

[0014] The inspection and tracking module obtains the information receiving time, departure time and arrival time of the assigned object, calculates the time difference between the information receiving time and the departure time to obtain the departure preparation time, and calculates the time difference between the departure time and the arrival time to obtain the task travel time; and obtains the processing end time of the assigned object, calculates the time difference between the processing end time and the arrival time to obtain the processing time of the corresponding abnormal type of the corresponding public equipment i, and sends the departure preparation time, task travel time and processing time to the operation and maintenance management platform for storage; it should be noted that the larger the values ​​of the departure preparation time and the task travel time, the less positive the inspection work attitude of the corresponding inspection and maintenance personnel, and the larger the value of the processing time, the lower the processing efficiency of the corresponding inspection and maintenance personnel for the corresponding type of public equipment. The above data are stored to provide data support for subsequent analysis and realize real-time updating of relevant data.

[0015] Further, the operation and maintenance management platform is communicatively connected with the task travel summary module, and the task information summary module collects all departure preparation times of the corresponding inspection and maintenance personnel, marks the number of tasks whose departure preparation time exceeds the preset departure preparation time threshold as the preparation timeout frequency, marks the ratio of the preparation timeout frequency to the total number of tasks as the preparation timeout ratio, and calculates the average of all departure preparation times to obtain the departure time value; and collects all task travel times of the corresponding inspection and maintenance personnel, marks the number of tasks whose task travel time exceeds the corresponding preset task travel time threshold as the travel timeout frequency, marks the ratio of the travel timeout frequency to the total number of tasks as the travel timeout ratio, marks the excess value of the task travel time compared to the corresponding preset task travel time threshold as the travel time excess value, and calculates the average of all travel time excess values ​​to obtain the time excess performance value; The preparation timeout ratio ZS, departure value CS, travel timeout ratio CB and time overtime performance value SB are numerically calculated through the formula CX=kp1*ZS+kp2*CS+kp3*CB+kp4*SB to obtain the effectiveness value CX, where kp1, kp2, kp3, kp4 are preset weight coefficients, and the values ​​of kp1, kp2, kp3, kp4 are all greater than zero; the larger the value of the effectiveness value CX, the less positive the inspection work attitude of the corresponding inspection and maintenance personnel, and the effectiveness value CX of the corresponding inspection and maintenance personnel is stored in the operation and maintenance management platform.

[0016] In addition, the operation and maintenance management platform is communicatively connected with the abnormality handling efficiency summary module. The abnormality handling efficiency summary module collects the total number of times the corresponding inspection and maintenance personnel handle the corresponding abnormality type of the corresponding public equipment and the duration of each processing, and calculates the ratio of the number of times the corresponding abnormality is resolved within the corresponding specified time to the total number of processing times to obtain the on-time processing ratio, and sums and calculates the advance resolution time for solving the corresponding abnormality within the corresponding specified time and takes the average to obtain the advance resolution time average, and calculates the weighted sum of the on-time processing ratio FT and the advance resolution time average FR by the formula JZ=b1*FT+b2*FR to obtain the inspection efficiency value JZ of the corresponding inspection and maintenance personnel for handling the corresponding abnormality type of the corresponding public equipment, wherein b1 and b2 are preset weight coefficients, b1>b2>0; and, the larger the value of the inspection efficiency value JZ, the faster the operation and maintenance personnel handle the abnormality of the corresponding abnormality type of the corresponding public equipment, and the inspection efficiency value JZ is stored in the operation and maintenance management platform.

[0017] The equipment comprehensive evaluation module conducts a comprehensive evaluation and analysis on the public equipment i, and generates an evaluation qualified signal or an evaluation warning signal based on this, and sends the evaluation qualified signal or the evaluation warning signal to the operation and maintenance management platform, so as to timely carry out maintenance of the corresponding public equipment and conduct cause investigation and tracing, thereby helping to ensure the stable operation of the public equipment i; the specific operation process of the equipment comprehensive evaluation module is as follows: the abnormal frequency and abnormal growth rate of the public equipment i in unit time are obtained, and the abnormal frequency and abnormal growth rate are numerically compared with the preset abnormal frequency threshold and the preset abnormal growth rate threshold respectively; if the abnormal frequency or the abnormal growth rate exceeds the corresponding preset threshold, an evaluation warning signal of the public equipment i is generated; if the abnormal frequency and the abnormal growth rate do not exceed the corresponding preset threshold, an evaluation qualified signal of the public equipment i is generated.

[0018] Embodiment 2: The difference between this embodiment and embodiment 1 is that, when generating the evaluation warning signal of the public device i, the environmental information (the environmental information is various environmental parameter data, including environmental temperature, environmental humidity, etc.) during the historical operation of the public device i is collected, and the various environmental parameter data are compared with the corresponding suitable environment requirements one by one. If the various environmental parameter data of the environment in which the public device i is located meet the requirements, it is judged that the public device i is in a suitable environment, otherwise it is judged that the public device i is in a vulnerable environment, and the length of time that the public device i is in the vulnerable environment during the historical operation process is marked as the vulnerable length YSi; and each abnormal moment in the historical operation process of the public device i is collected, the time difference between two adjacent groups of abnormal moments is calculated to obtain the abnormal interval length, and the average of all abnormal interval lengths of the public device i is calculated to obtain the abnormal performance value YJi; The time of use of public equipment i is obtained and marked as TSi. The vulnerable time YSi, the abnormal performance value YJi and the time of use TSi of public equipment i are normalized by the formula SYi=(fs1*YSi+fs3*TSi) / (fs2*YJi+1.682)to obtain the design difference coefficient SYi, where fs1, fs2, and fs3 are preset proportional coefficients, and the values ​​of fs1, fs2, and fs3 are all greater than zero; and the value of the design difference coefficient SYi The size is directly proportional to the vulnerable time YSi and the time of commissioning TSi, and inversely proportional to the abnormal performance value YJi. The larger the value of the deviation coefficient SYi, the worse the equipment condition of the corresponding public equipment i is, and the more timely replacement is needed; the deviation coefficient is numerically compared with the preset deviation coefficient threshold. If the deviation coefficient exceeds the preset deviation coefficient threshold, a high-loss signal of public equipment i is generated; the high-loss signal of public equipment i is sent to the operation and maintenance management platform so that the corresponding public equipment can be replaced in time.

[0019] The working principle of the present invention is as follows: when in use, the public equipment to be managed is monitored through the operation and maintenance management platform to determine whether there is any operational abnormality. When an operational abnormality occurs, the abnormality type is sent to the inspection and allocation module. The inspection and allocation module sets up a screening area and obtains all the preliminary personnel, analyzes the preliminary personnel to obtain the corresponding inspection value, determines the allocation object based on the numerical value of the inspection value, sends the location, abnormality type and optimal travel path of the corresponding public equipment to the intelligent terminal of the allocation object, and the allocation object promptly goes to the location of the corresponding public equipment i and handles the abnormality, so as to realize the rapid handling of the public equipment related abnormalities; the equipment comprehensive evaluation module conducts a comprehensive evaluation and analysis on the public equipment, and generates an evaluation qualified signal or an evaluation warning signal accordingly, and sends the evaluation qualified signal or the evaluation warning signal to the operation and maintenance management platform, so as to timely perform maintenance on the corresponding public equipment and conduct cause investigation and tracing, thereby helping to ensure the stable operation of the public equipment i, and when the evaluation warning signal is generated, the corresponding public equipment continues to be analyzed to determine whether a high-loss signal is generated, so as to timely replace the corresponding public equipment.
