Description

Technical Field

[0001] The present invention relates to the technical field of digital management of power grid communications, and in particular to a digital management system for power grid communications maintenance operation processes. Background Art

[0002] The power communication network came into being to ensure the safe and stable operation of the power system. It is used to ensure the safe, stable and economical operation of the power grid and is an important infrastructure of the power system.

[0003] Prior art CN102663545A discloses a distribution network maintenance operation management system based on a smart phone, including using a Windows Mobile smart phone as a communication client, using the GPRS module of the smart phone to remotely transmit data, sound and images, and solving the communication problems caused by the large number of distribution points and messy locations of the distribution network. At the same time, the smart phone and the GPRS mobile communication network can be used to transmit on-site data, sound and images to the WEB server in real time, so as to facilitate the collaborative work between the WEB server and the on-site staff.

[0004] When power communications are undergoing maintenance, the allocation of maintenance resources is mostly based on the work experience of the maintenance management. However, allocating maintenance resources based on manual experience will result in a mismatch between the allocated resources and the actual fault maintenance, including over-allocation and under-allocation of personnel, which will reduce the maintenance efficiency of power grid communications. Summary of the invention

[0005] The purpose of the present invention is to solve the problems in the background technology and to propose a digital management system for power grid communication maintenance operation process.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] A digital management system for power grid communication maintenance operation process, comprising:

[0008] The operation response module is used to identify the early warning response signal of the target power grid, obtain the power grid operation data, and mark it as abnormal operation data;

[0009] A process allocation module is used to determine the amount of work allocation according to the abnormal operation data, including calculating the characteristic value of the abnormal operation data, determining the abnormal items of the abnormal operation data, and then determining the target work process based on the abnormal items, searching the target work process in the historical maintenance information, determining the comparison information, and then obtaining the maintenance evaluation value in the comparison information, and determining the amount of work allocation based on the maintenance evaluation value;

[0010] Task tracking module, used to track the target operation process in real time and generate maintenance completion signal;

[0011] The status acceptance module is used to identify the maintenance completion signal and accept the maintenance results. By performing signal tests on abnormal items, the real-time communication speed and real-time monitoring data are obtained, and the normal operating value of the equipment at this time is calculated. Then, based on the normal operating value of the equipment, the maintenance signal and the terminal confirmation signal are determined. When the terminal confirmation signal is generated, the real-time maintenance information of the target operation process is obtained, and the maintenance evaluation value of the target operation process is calculated.

[0012] As a further solution of the present invention, it is characterized in that the process allocation module includes a feature recognition unit and an allocation processing unit. The feature recognition unit is used to determine the characteristics of abnormal data and judge abnormal items. The allocation processing unit analyzes abnormal items based on historical maintenance information and determines the job allocation amount.

[0013] As a further solution of the present invention, the method for determining abnormal items includes:

[0014] Acquire abnormal operation data within a unit time, and calculate characteristic values ​​of the abnormal operation data, wherein the characteristic values ​​of the power grid operation data include mean value, median, mode, variance and standard deviation, and the unit time is a threshold;

[0015] Calculate the similarity between the characteristic value of the abnormal operation data and the standard characteristic value of the abnormal item by using the Pearson similarity algorithm, and determine the abnormal item of the abnormal operation data based on the calculation result;

[0016] Among them, the abnormal items are the types of power grid communication failures, including optical fiber failures and cable failures.

[0017] As a further solution of the present invention, a method for determining the job allocation amount includes:

[0018] Based on the abnormal items of abnormal data types, determine the maintenance process of the abnormal items and mark them as target operation processes;

[0019] The target operation process is used as the search subject to search in the historical maintenance information, and the search results are marked as reference information i, where i represents the operation number of different maintenance operations, and i∈[1, I], indicating that there are I search results in total;

[0020] The specific contents of historical maintenance information include fault type, abnormal operation data, number of maintenance personnel, maintenance time and maintenance evaluation value;

[0021] Among them, the maintenance evaluation value refers to the evaluation score obtained after evaluating the power grid communication according to the maintenance cycle;

[0022] Then, according to the maintenance evaluation value, the comparison information i with the highest maintenance evaluation value is obtained, and based on the number of maintenance personnel in this comparison information, the number of maintenance personnel is marked as the job allocation.

[0023] As a further solution of the present invention, when the job allocation amount is set, a process start signal is generated, and then the allocation processing unit transmits the process start signal to the task tracking module;

[0024] The task tracking module is used to track the target operation process in real time. When the target operation process is completed, a maintenance completion signal is generated and transmitted to the status acceptance module;

[0025] Among them, the tracking content includes maintenance time and the progress of the target operation process.

[0026] As a further solution of the present invention, a method for calculating the normal operating value of the equipment includes:

[0027] Obtain the location of the abnormal item, mark the communication device at this location as the target device, obtain the distance between the communication control station and the target device, and mark it as the communication distance;

[0028] Then the communication control center transmits the test signal to the target device, and records the time when the target device receives the test signal and marks it as the interval time;

[0029] Divide the communication distance by the interval time, and mark the result as real-time communication speed VS. At the same time, obtain the real-time monitoring data JS collected by the target device, and based on the formula Determine the normal operation value SZ of the equipment, where VY is the normal communication rate of the power grid, 0<a1<1, JC represents the real-time standard data of the operation of the power grid, and λ1 and λ2 are both proportional coefficients.

[0030] As a further solution of the present invention, the normal operation value SZ of the equipment is compared with the operation threshold value X1. When SZ < X1, a maintenance verification signal is generated and transmitted to the task tracking module. On the contrary, when SZ ≥ X1, a terminal confirmation signal is generated.

[0031] When a terminal confirmation signal is generated, it indicates that the abnormal items of the power grid communication have been repaired and can communicate normally. When a maintenance verification signal is generated, it indicates that the power grid communication is still abnormal. At this time, the abnormal items need to be re-repaired until a terminal confirmation signal is generated.

[0032] As a further solution of the present invention, a method for calculating the maintenance evaluation value includes:

[0033] Obtain real-time maintenance information of the target operation process, including maintenance cycle time Tz, maintenance personnel PR and operation cycle time Ty;

[0034] Among them, the maintenance cycle time Ty refers to the time interval between the start of the generation process start signal and the end of the terminal confirmation signal generation, and the operation cycle time refers to the normal operation time of the power grid communication after the terminal confirmation signal is generated;

[0035] Then use the formula The maintenance evaluation value Xp of the target operation process is obtained, where b, c1 and c2 are constant coefficients, and c1>0, c2>0.

[0036] As a further solution of the present invention, when the status acceptance module generates a maintenance evaluation value, the maintenance evaluation value is transmitted to the integrated storage module and stored by the integrated storage module.

[0037] The integrated storage module is also used to classify and store power grid operation information, wherein the power grid operation information includes regional distribution information of the target power grid, normal operation parameter information, employee status information, historical operation data and historical maintenance information.

[0038] Compared with the prior art, the advantages of the present invention are:

BRIEF DESCRIPTION OF THE DRAWINGS

[0040] Figure 1 It is a schematic diagram of the system structure of the present invention. DETAILED DESCRIPTION

[0041] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0042] Reference Figure 1 , a digital management system for power grid communication maintenance operation process, including an integrated storage module, an operation response module, a process allocation module, a task tracking module and a status acceptance module;

[0043] The integrated storage module is used to classify and store the power grid operation information, wherein the power grid operation information includes the regional distribution information of the target power grid, normal operation parameter information, employee status information, historical operation data and historical maintenance information;

[0044] The operation response module is used to identify the early warning response signal of the target power grid, and when the operation response module detects the early warning response signal, it immediately obtains the power grid operation data, marks it as abnormal operation data, and transmits it to the process allocation module at the same time;

[0045] Among them, the early warning response signal refers to the signal generated when the real-time collected power grid operation data is inconsistent with the normal operation parameter information;

[0046] The process allocation module is used to determine the amount of job allocation based on abnormal operation data, wherein the process allocation module includes a feature recognition unit and an allocation processing unit, the feature recognition unit is used to determine the abnormal data features and judge the abnormal items, and the allocation processing unit analyzes the abnormal items based on historical maintenance information and determines the amount of job allocation;

[0047] Among them, the methods for judging abnormal items include:

[0048] Acquire abnormal operation data within a unit time, and calculate characteristic values ​​of the abnormal operation data. In this embodiment, the characteristic values ​​of the power grid operation data include the mean, median, mode, variance, and standard deviation. The unit time is the threshold, and the specific time length is set according to the big data experience of those skilled in the art;

[0049] Then, the characteristic value of the abnormal operation data and the standard characteristic value of the abnormal item are calculated for similarity, and the abnormal item of the abnormal operation data is determined based on the calculation result;

[0050] Among them, the abnormal items are types of power grid communication faults, including optical fiber faults and cable faults, etc. The standard characteristic values ​​of the abnormal items are obtained by technicians in this field based on multiple simulation operations on historical operation data. At the same time, the similarity calculation method in this embodiment is selected as the Pearson similarity algorithm. The specific calculation process is the existing technology and will not be repeated here.

[0051] The calculation method of the activity allocation includes:

[0052] Based on the abnormal items of abnormal data types, determine the maintenance process of the abnormal items and mark them as target operation processes;

[0053] The target operation process is used as the search subject to search in the historical maintenance information, and the search results are marked as reference information i, where i represents the operation number of different maintenance operations, and i∈[1, I], indicating that there are I search results in total;

[0054] The specific contents of historical maintenance information include fault type, abnormal operation data, number of maintenance personnel, maintenance time and maintenance evaluation value;

[0055] Among them, the maintenance evaluation value refers to the evaluation score obtained after evaluating the power grid communication according to the maintenance cycle;

[0056] Then, according to the maintenance evaluation value, the comparison information i with the highest maintenance evaluation value is obtained, and based on the number of maintenance personnel in the comparison information, the number of maintenance personnel is marked as the job allocation;

[0057] When the job allocation amount is set, a process start signal is generated, and then the allocation processing unit transmits the process start signal to the task tracking module;

[0058] The task tracking module is used to track the target operation process in real time. When the target operation process is completed, a maintenance completion signal is generated and transmitted to the status acceptance module;

[0059] Among them, when the target operation process is tracked in real time, the tracking content includes the maintenance time, the progress of the target operation process, etc.;

[0060] The status acceptance module is used to identify the maintenance completion signal and accept the maintenance results of the target operation process. At the same time, the maintenance evaluation value of the target operation process is determined according to the acceptance results. The specific processing methods of the status acceptance module include:

[0061] S01: When the maintenance completion signal is identified, a signal test is performed on the abnormal item. The specific signal test method includes:

[0062] Obtain the location of the abnormal item, mark the communication device at this location as the target device, obtain the distance between the communication control station and the target device, and mark it as the communication distance;

[0063] Then the communication control center transmits the test signal to the target device, and records the time when the target device receives the test signal and marks it as the interval time;

[0064] Divide the communication distance by the interval time, and mark the result as real-time communication speed VS. At the same time, obtain the real-time monitoring data JS collected by the target device, and based on the formula Determine the normal operation value SZ of the equipment, where VY is the normal communication rate of the power grid, 0<a1<1, JC represents the real-time standard data of the operation of the power grid, λ1 and λ2 are both proportional coefficients, and the specific values ​​of a1, λ1 and λ2 are obtained by technicians in this field after big data calculation;

[0065] Among them, the communication control station refers to the terminal for signal integration in power grid communication. The test signal is set by technical personnel in this field based on big data experience. At the same time, the normal operating value of the equipment is used to evaluate the maintenance results of abnormal items. When the normal operating value of the equipment is larger, the maintenance effect is better. When the normal operating value of the equipment is smaller, the maintenance effect is worse.

[0066] Compare the normal operation value SZ of the equipment with the operation threshold value X1. When SZ<X1, a maintenance verification signal is generated and transmitted to the task tracking module. Conversely, when SZ≥X1, a terminal confirmation signal is generated.

[0067] The operation threshold value X1 is obtained by technicians in this field after big data calculation;

[0068] The terminal confirmation signal indicates that the abnormal items of the power grid communication have been repaired and can communicate normally, and the maintenance verification signal indicates that the power grid communication is still abnormal. At this time, the abnormal items need to be repaired again until the terminal confirmation signal is generated;

[0069] S02: When the terminal confirms the signal, the real-time maintenance information of the target operation process is obtained, wherein the real-time maintenance information includes the maintenance cycle time Tz, the maintenance personnel PR and the operation cycle time Ty;

[0070] It should be further explained that the maintenance cycle time Ty refers to the time interval between the start of the generation process start signal and the end of the generation of the terminal confirmation signal, and the operation cycle time refers to the normal operation time of the power grid communication after the terminal confirmation signal is generated. Furthermore, the method for determining the operation cycle time is determined by the next abnormal time of the power grid communication;

[0071] Then use the formula Obtain the maintenance evaluation value Xp of the target operation process, where b, c1 and c2 are constant coefficients, and c1>0, c2>0, and the specific values ​​of b, c1 and c2 are obtained by technicians in this field after big data calculation;

[0072] The maintenance evaluation value indicates the score of the implementation process of the target operation process. The higher the maintenance evaluation value, the higher the maintenance efficiency and maintenance quality of the target operation process. On the contrary, the lower the maintenance evaluation value, the lower the maintenance efficiency and maintenance quality of the target operation process.

[0073] The status acceptance module then transmits the maintenance evaluation value to the integrated storage module, which then stores it.

[0074] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
