[0001] The present invention relates to the technical field of operation and maintenance management and control, and in particular to a digital evaluation management method and system for substation operation and maintenance inspection task risks. Background Technique

[0002] Substation operation and maintenance inspection tasks involve certain risks, mainly including the following aspects: electrical shock risk, equipment operation risk, chemical risk, high-altitude operation risk, fire and explosion risk; to reduce these risks, substation operation and maintenance personnel need to receive professional training, strictly abide by operating procedures and safety operation specifications, and be equipped with appropriate personal protective equipment to ensure safe production.

[0003] When the existing substation operation and maintenance inspection task risk control scheme is implemented, it cannot count, process and integrate all the operation and maintenance accident data that has occurred in history, and thus cannot expand and utilize the operation and maintenance accident data. At the same time, it cannot adaptively adjust the supervision and risk warning of substation equipment operation and maintenance inspection tasks by combining the historical operation and maintenance data of operation and maintenance personnel with the operation and maintenance accident data, resulting in poor adaptive adjustment ability and poor effect of substation operation and maintenance inspection task risk control. Summary of the Invention

[0005] The purpose of the present invention can be achieved by the following technical solutions:

[0006] A digital evaluation management method for substation operation and maintenance inspection task risks includes:

According to the update instruction, count the total number of times the accident operation corresponding to this standard operation has occurred historically and the accident type corresponding to each accident operation, and calculate through the formula to obtain the operation risk coefficient corresponding to the standard operation ; in the formula, C is the total number of times the accident operation corresponding to the standard operation has occurred historically, is the influence weight of the accident type corresponding to each accident operation;

[0019] Sort and combine all the operation risk coefficients of the operation sequence corresponding to the device to obtain the operation risk coefficient array of the device.

[0022] In an optional implementation manner, count the total number of different accident types that have occurred in the history of the operation and maintenance personnel according to the regulation instruction, as well as all the target accident devices corresponding to the different accident types that have occurred in the history, and input the name of the device to be operated and maintained into the historical accident integration diagram for traversal and retrieval to obtain the corresponding associated device risk coefficient , through the formula Calculate and obtain the standard integration degree of the operation and maintenance personnel for the device to be operated and maintained ; in the formula, N is the total number of different accident types that have occurred in the history of the operation and maintenance personnel, is the total number of times the operation and maintenance personnel have historically carried out device operation and maintenance.

[0023] In an optional implementation manner, when dynamically controlling the task risk of the operation and maintenance personnel for the device to be operated and maintained by using the standard integration degree, input the standard integration degree into the standard risk identification model for data analysis and output the corresponding control identifier. The expression of the standard risk identification model is ; in the formula, is the standard integration standard value corresponding to the device to be operated and maintained;

[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by ordinary operation and maintenance personnel in the art based on the embodiments of the present invention without creative labor belong to the scope of protection of the present invention.

[0037] As Figure 1 shown, the present invention is a method for digital evaluation and management of substation operation and maintenance task risks, including:

[0038] Counting and processing all shared and updated operation and maintenance accidents that have occurred to obtain a historical accident integration diagram; including:

[0039] Obtaining and recording all operation and maintenance accidents updated in real time on the operation and maintenance sharing platform, where the operation and maintenance accidents include accident type, accident equipment, accident operation, place of occurrence, time of occurrence, accident responsible personnel, and accident leading responsible personnel;

[0040] Among them, the accident type includes high-impact types and medium-impact types; specifically, the high-impact type is the accident type, and the medium-impact type is the type of non-compliant operation but without accidents;

[0041] As Figure 2 shown, the high-impact type and the medium-impact type in the accident type are respectively set as the first root node and the second root node, and the accident equipment is set as the first sub-node and synchronously bound and associated to the corresponding root node, and the accident operation is set as the second sub-node and synchronously bound and associated to the corresponding first sub-node;

[0042] Combining the place of occurrence, time of occurrence, accident responsible personnel, and accident leading responsible personnel to obtain associated occurrence data and setting it as the third sub-node and synchronously binding and associating it to the corresponding second sub-node;

[0043] Among them, the accident responsible personnel are the operation and maintenance personnel for operation and maintenance, and the accident leading responsible personnel are the management personnel at the level above the accident responsible personnel;

[0044] Sort and combine the first and second root nodes for real-time data update and all associated child nodes to obtain an integrated historical accident diagram and synchronously upload it to the operation and maintenance shared platform for shared data update;

[0045] In the embodiments of the present invention, by statistically processing and integrating all operation and maintenance accidents with shared updates that have occurred, an integrated historical accident diagram is obtained. This can not only provide a concise and intuitive digital display of different types of operation and maintenance accident data that have occurred in the past, but also provide support for historical risk data for the adaptive dynamic control of the risks of subsequent substation equipment operation and maintenance tasks, improving the necessity of processing the integrated historical accident diagram and the diversity of its utilization.

[0046] Use the existing operation and maintenance requirement data to digitally process and update the risks of different accident operations and the corresponding accident equipment risks in the integrated historical accident diagram, obtain the corresponding operation risk coefficients and equipment risk coefficients, and synchronously store all the processed operation risk coefficients and equipment risk coefficients in the corresponding accident operation nodes and accident equipment nodes in the integrated historical accident diagram for shared update of risk digital data; including:

[0047] Traverse and count all accident equipment and their associated accident operations that appear in all child nodes of the integrated historical accident diagram, and number and mark all accident equipment according to the time sequence of appearance;

[0048] Sequentially obtain the operation and maintenance requirement data corresponding to the accident equipment, and traverse and count the standard operations of different marked types for the operation and maintenance requirement data;

[0049] Among them, the operation and maintenance requirement data includes different operation steps and operation parts corresponding to the equipment, as well as operation requirements and operation risk prompts corresponding to different operation steps. The operation and maintenance requirement data can be determined based on the design requirement parameters of the corresponding equipment, or according to the actual operation and maintenance requirements of the substation where it is located;

[0050] As Figure 3 shown, when digitally processing the risks of different accident operations in the integrated historical accident diagram, obtain the standard operations of different marked types and traverse and match them with the integrated historical accident diagram to check if there are accident operations;

[0051] If there is no accident operation, generate a maintenance instruction, do not update the operation weight corresponding to this standard operation, and mark it as the operation risk coefficient ;

[0052] Among them, a corresponding marked type is preset for different standard operations, and the marked type is used to textually represent the importance of the standard operation; the marked type includes but is not limited to ordinary operation type, low-risk operation type, and high-risk operation type;

[0053] In addition, a corresponding operation weight is preset for different standard operations. The operation weight is used to numerically represent the importance of the standard operation, and the specific value can be determined by the standard data formulated by those skilled in the art;

[0054] If there is an accident operation, an update instruction is generated and the operation weight corresponding to the standard operation is updated. According to the update instruction, the total number of times the accident operation corresponding to the standard operation has occurred in history and the accident type corresponding to each accident operation are counted, and through the formula the operation risk coefficient corresponding to the standard operation is calculated and obtained ; in the formula, C is the total number of times the accident operation corresponding to the standard operation has occurred in history, is the accident type impact weight corresponding to each accident operation. A corresponding accident type impact weight is preset for different accident types. The accident type impact weight corresponding to the high impact type is greater than the accident type impact weight corresponding to the medium impact type. The values of the accident type impact weights corresponding to the high impact type and the medium impact type can be 2 and 1 respectively;

[0055] Sort and combine all the operation risk coefficients of the operation sequence corresponding to the device to obtain an operation risk coefficient array of the device;

[0056] It should be noted that by digitally processing the risks of different accident operations in the historical accident integration diagram, it is possible to not only expand the utilization of the processing data of all the operation and maintenance accidents that have occurred in history, realize the digital dynamic update of the operation and maintenance risks of different devices, but also provide timely and reliable device real-time risk data support for the risk update of the operation and maintenance practical tasks of the operation and maintenance personnel corresponding to different devices in the future. Compared with the single data record of all the operation and maintenance accident data that have occurred in history in the existing technical solution, and the inability to perform real-time dynamic processing update and expansion utilization of the risks of different substation devices, the embodiment of the present invention can effectively improve the ability and effect of the adaptive adjustment of different operation risks associated with the operation and maintenance equipment of the substation;

[0057] When digitally processing the risks of different accident devices in the historical accident integration diagram, the corresponding operation risk coefficient array is obtained according to the accident device name, the values corresponding to different elements in the operation risk coefficient array are traversed and counted, and the sum of all elements in the operation risk coefficient array is obtained through the summation formula to obtain the device risk coefficient corresponding to the accident device ;

[0058] In the embodiments of the present invention, by digitally processing and updating the risks of different accident operations and the corresponding accident equipment risks, the corresponding operation risk coefficients and equipment risk coefficients are obtained, realizing the effective digital utilization of all the historical maintenance accident handling data that has occurred, and at the same time realizing the dynamic update of the risks of different equipment and the operation steps associated with different equipment, further improving the processing and expansion effect of the corresponding data in the historical accident integration diagram and the reliability of subsequent utilization.

[0059] Analyze and evaluate the specification status corresponding to the different equipment maintenance and repair operations historically implemented by maintenance personnel, and dynamically control the risks of the substation maintenance and repair tasks they implement according to the evaluation results and the historical accident integration diagram updated in combination with real-time data; including:

[0060] Obtain the historical maintenance and repair data corresponding to the maintenance personnel and traverse and count whether there is an accident type. If there is no accident type, generate a regular instruction and give targeted prompts for the entire operation process according to the existing maintenance and repair requirement plans corresponding to the equipment to be maintained and repaired.

[0061] If there is an accident type, generate a regulation instruction and conduct a supervision and analysis of the equipment operation and repair requirements implemented by the maintenance personnel.

[0062] It should be noted that when there is an accident type in the historical maintenance and repair data of the maintenance personnel, it means that the practical operation risk of this type of maintenance personnel is greater than that of the maintenance personnel without an accident type. Therefore, targeted risk control needs to be implemented for their maintenance and repair tasks. In the embodiments of the present invention, by integrating the historical maintenance and repair risk data of the maintenance personnel and the historical accident risk data corresponding to the equipment to be maintained and repaired, multi-dimensional risk data integration processing and analysis are realized, which can provide reliable data support for the adaptive adjustment of the risk control of subsequent maintenance and repair tasks;

[0063] Such as Figure 4 shown, according to the regulation instruction, count the total number of different accident types historically occurred by the maintenance personnel, and all the target accident equipment corresponding to the different accident types historically occurred, and input the name of the equipment to be maintained and repaired into the historical accident integration diagram for traversal and retrieval to obtain the corresponding associated equipment risk coefficient , and calculate and obtain the specification integration degree of the maintenance personnel's operation on the equipment to be maintained and repaired through the formula ; in the formula, N is the total number of different accident types historically occurred by the maintenance personnel, is the total number of times the maintenance personnel have historically implemented equipment maintenance and repair; is the total number of times the maintenance personnel have historically implemented equipment maintenance and repair;

[0064] In an embodiment of the present invention, the specification integration degree is a value used to evaluate the operation and maintenance inspection specifications to be implemented by operation and maintenance personnel by integrally calculating the historical risk operation data of operation and maintenance personnel and the historical risk accident data of corresponding devices;

[0065] When dynamically controlling the task risk of the operation and maintenance personnel for the device to be operation and maintained by using the specification integration degree, the specification integration degree is input into the specification risk identification model for data analysis and the corresponding control identification is output. The expression of the specification risk identification model is ; In the formula, is the specification integration standard value corresponding to the device to be operation and maintained. The specification integration standard value can be determined according to the device risk coefficient of the device to be operation and maintained in the historical accident integration diagram. The specification integration standard value can be twice the value of the device risk coefficient of the device to be operation and maintained in the historical accident integration diagram;

[0066] Among them, the value of the control identification is 0 or 1, corresponding to the existing operation and maintenance inspection requirement scheme or the updated operation and maintenance inspection requirement strengthening scheme respectively; The strictness of the operation step requirements corresponding to the updated operation and maintenance inspection requirement strengthening scheme is higher than that of the operation step requirements corresponding to the existing operation and maintenance inspection requirement scheme;

[0067] Implement the existing operation and maintenance inspection requirement scheme for the entire operation process of the operation and maintenance personnel for the device to be operation and maintained according to the control identification with a value of 0 and give targeted operation risk prompts;

[0068] And, implement the updated operation and maintenance inspection requirement strengthening scheme for the entire operation process of the operation and maintenance personnel for the device to be operation and maintained according to the control identification with a value of 1 to give targeted operation risk prompts.

[0072] The evaluation and control module is used to analyze and evaluate the compliance status corresponding to different equipment operation and maintenance repairs historically implemented by operation and maintenance personnel, and dynamically control the risks of the substation operation and maintenance tasks they implement based on the evaluation results and the historical accident integration diagram updated with real-time data.

[0073] In the embodiments of the present invention, by analyzing and evaluating the compliance status corresponding to different equipment operation and maintenance repairs historically implemented by operation and maintenance personnel and using the updated historical accident integration diagram to dynamically control the risk solutions of the equipment operation and maintenance tasks they implement adaptively, the ability and effect of the adaptive adjustment of risk control corresponding to different operation and maintenance personnel and different equipment are improved.
