[0027] The present application inventors continue to study how to effectively solve the generation method of secondary operation tickets and work tickets, how to solve the current manual method of formulating secondary operation tickets and work tickets, which has the problems of low work efficiency and easy errors in manual formulation of secondary operation tickets and work tickets, thereby causing the operation safety of the substation. The research of the inventors at least includes: how to obtain a substation secondary operation library, and build an association model therefrom, and formulate secondary operation tickets and work tickets through the association model. After a large number of repeated studies, the inventors propose the generation method and system of secondary operation tickets and work tickets of the present application.

[0028] Before describing the embodiments of the present application in detail, the design idea of the present application is outlined as follows. Referring to the accompanying Figure 2 The present application designs a generation method of secondary operation tickets and work tickets, which obtains a substation secondary operation library, builds an association model therefrom, formulates secondary operation tickets and work tickets through the association model, and finally performs safety verification on the operation record. The present application realizes a standardized operation process in combination with a safety verification mechanism, and has the advantages of improving the generation efficiency of operation tickets, reducing safety risks, and guaranteeing the specification of maintenance.

[0029] Compared with the prior art, the traditional method relies on manual field recording of device parameters and connection relationship, and has problems of data update lag, information omission, etc. The scheme ensures strict synchronization of operation library data and field device state by automatically collecting SCD model files and real-time monitoring data. In the prior art, device information is usually saved in the form of paper drawings, which cannot support dynamic correlation analysis, while the digital operation library established by the scheme can directly interface with the functional modeling system to provide accurate data source for subsequent operation ticket generation.

[0030] The application solves the technical problems of low efficiency and error-prone of traditional manual collection of device data, and realizes automatic collection and dynamic update of secondary system device information. The secondary operation library established by real-time data records device running parameters and correlation relationship, providing an accurate data basis for subsequent construction of correlation models and avoiding safety measure loopholes caused by manual recording errors.

[0031] Referring to the accompanying Figure 1 The embodiment of the application provides a secondary operation ticket and work ticket generation method, comprising the following steps: Step S001: Obtain substation data and establish a substation secondary operation library.

[0032] Further, the substation data is obtained and the substation secondary operation library is established: real-time data of device operation of the substation is obtained, the real-time data includes device information, line information and logical relationship of all devices of the substation, and the substation secondary operation library is established according to the real-time data.

[0033] The real-time data of the real-time library is obtained. The real-time library uses SQL Server2019 database management system, and high-efficiency data read-write operation is realized through ODBC data source connection pool technology.

[0034] The real-time data includes device function definition, function description, operation rule, maintenance period, operation rule and device real-time running state.

[0035] The substation secondary operation library is established, which includes device function definition and operation rule.

[0036] According to the extracted basic data and analysis results, a correlation model containing device function description, operation rule, maintenance period, etc. is constructed. In an embodiment, the correlation model is stored in GraphML format, which can realize visual display of the correlation relationship between devices.

[0037] The real-time data refers to dynamic monitoring data generated during the operation of the equipment, and can be collected in real time by sensors, intelligent terminals or monitoring systems deployed in the substation, and is used to reflect the current operation state of the equipment.

[0038] The equipment information refers to structured data including equipment model, functional parameters and installation position, and can be obtained by digitizing equipment nameplate information or analyzing SCD model files, and is used to establish a unique identification of the equipment.

[0039] The line information refers to the electrical connection topology relationship, and can be obtained by analyzing the logical node association relationship in the intelligent substation virtual terminal connection table or SCD file, and is used to construct the secondary circuit logic architecture.

[0040] The logical relationship refers to the signal transmission path between secondary devices, and can be obtained by analyzing the GOOSE / SV message transmission configuration table or virtual circuit connection relationship table, and is used to describe the control linkage mechanism between devices.

[0041] Specifically, during the operation of the intelligent substation, the equipment operation data is collected by the merging unit and the intelligent terminal deployed in the bay layer, and the equipment configuration parameters recorded in the SCD model file are obtained from the station control layer. The equipment information is obtained by analyzing the instantiation description information of the IED device in the SCD file, such as the device type code and the logical node naming rule. The line information is generated by extracting the pre-defined virtual terminal connection relationship table in the SCD file, such as the SV input association between the merging unit and the protection device. The logical relationship is constructed by analyzing the GOOSE subscription and publication relationship table, such as the trip signal transmission path between the intelligent terminal and the measurement and control device. After standardization processing, all data are stored as real-time database containing time stamp, forming the secondary operation library covering all devices in the station.

[0042] Step S002: parsing the basic data from the substation secondary operation library, and constructing the association model through the basic data.

[0043] In the further embodiment, the parsing of the basic data from the substation secondary operation library is: In the embodiment, the real-time data in the substation secondary operation library, including the data in the SSD, SCD and SDD files, is parsed into standard data in JSON format by using an open-source XML parser, and the basic data is obtained by extracting the key information of the equipment from the standard data, including the equipment information of the substation and the association between the equipment.

[0044] The embodiment is that the open source XML parser JDOM2 is used for parsing, and key information is extracted from the parsed data. For complex data structures, the XML data is converted into JSON format which is easy to process by using XSLT conversion technology. The key information includes interval information, cubicle information, device information, terminal information, and connection relationship between terminals.

[0045] The embodiment is that the real-time data is imported into the parsing unit to parse the substation model file, obtain basic data such as device information, line information and logical relationship of the substation, and then batch import these data into the substation secondary operation library.

[0046] The standard data in JSON format refers to data stored in a structured text form, which can be implemented by using JavaScript Object Notation syntax rules, and describes device attributes and associated relationships through key-value pair structure. The key information of the device refers to core parameters related to substation operation, which can be extracted by using a data filtering algorithm to extract device name, model, installation position and logical connection relationship. The key information of the device provides structured input for the associated model and ensures the accuracy of the device operation rules.

[0047] Specifically, in the implementation process, the real-time data is first converted into standard data in JSON format, for example, the original information such as device status and line topology is converted into a standardized structure containing "deviceID", "connectionNodes" and other fields. Then, the device name, port configuration and virtual terminal connection relationship are extracted through the data parsing module to form a basic data set containing device basic attributes and associated matrix. The standardized data layer established in this way can eliminate the differences in different device data formats and provide consistent data sources for subsequent establishment of device function model.

[0048] Compared with the prior art, the traditional method relies on manual parsing of device configuration files or drawing information, and has problems such as non-uniform data format and difficulty in identifying association. The present scheme avoids missing device information or misjudgment of associated relationship caused by manual operation through forced data standardization and automatic extraction, and can accurately restore the logical topology of the secondary system, especially when dealing with invisible connection relationships such as virtual terminals and virtual loops.

[0049] Through the above technical scheme, the present application realizes automatic parsing and key information extraction of secondary device data, solves the problems of low efficiency and easy error of traditional manual parsing, ensures the integrity of device basic data and the accuracy of associated relationship, and lays a data foundation for subsequent generation of operation tickets in accordance with safety regulations.

[0050] The embodiment further comprises the following steps of: constructing an associated model through the basic data. configuration information and position information of the secondary equipment are analyzed from the parsed standard data; a connection relationship between the equipment is established according to a connection rule of the equipment, so that a signal transmission relationship between the equipment is analyzed; a correlation model is constructed according to the basic data and the signal transmission relationship, and the correlation model includes equipment function description, operation rule, maintenance period and relationship between the equipment.

[0051] In an embodiment, the configuration information refers to the type, parameter and running state of the secondary equipment, and can be implemented by a device model database matching mode, and is used to determine the function positioning of the equipment in the system. The position information refers to the physical installation position of the equipment in the transformer substation, and can be recorded by a GIS coordinate system, and is used to establish the corresponding relationship between the equipment and the physical space. The connection rule refers to the allowed communication protocol and interface standard between the equipment, and can be defined by IEC 61850 protocol, and is used to ensure the compliance of data interaction between the equipment. The signal transmission relationship refers to the data flow direction and logical dependency relationship between the equipment, and can be implemented by analyzing the virtual loop information in the SCD file, and is used to determine the influence range of the maintenance operation on the system. The correlation model refers to a structured data set integrating the equipment attributes and the interaction relationship, and can be stored by a graph database, and is used to support logical verification during generation of the operation ticket.

[0052] Specifically, after parsing the standard data, first, the configuration information such as the device model and the port parameter is extracted, and the physical position of the equipment is determined in combination with the GIS coordinate. Then, according to the preset communication protocol rule, the logical connection topology between the equipment is established, such as the sampling value transmission link between the merging unit and the protection device. By analyzing the virtual terminal connection relationship in the SCD file, the signal transmission path and the associated equipment set are further determined. Finally, the equipment attributes, the connection topology and the signal dependency relationship are integrated into a structured model including the function description, the operation constraint and the maintenance period, for example, the binding relationship between the value modification operation of the protection device and the state of the associated soft pressure plate.

[0053] Compared with the prior art, the existing method relies on manual analysis of the equipment connection relationship, and needs to check the signal transmission path by paper drawings, which has the problems of low efficiency and easy omission. The present scheme can complete the logical correlation between the equipment by automatically parsing the equipment configuration and the virtual loop information, and avoid the misjudgment of the topology relationship caused by manual operation.

[0054] Through the above technical scheme, the present application can automatically identify the signal transmission dependency relationship between the secondary equipment, and ensure that all associated safety measures of the equipment are accurately covered during generation of the operation ticket. For example, when a certain intelligent terminal is disconnected, the maintenance pressure plate and the associated protection device that need to be operated synchronously can be automatically associated, so as to avoid the risk of misoperation of the live equipment caused by human error.

[0055] The application further proposes analyzing configuration information and position information of the secondary equipment from the parsed standard data; establishing a connection relationship between each equipment according to a connection rule of the equipment, so as to analyze a signal transmission relationship between the equipment; and constructing a correlation model from the basic data and the signal transmission relationship, the correlation model including equipment function description, operation rule, maintenance period and the relationship between the equipment.

[0056] The configuration information refers to the type, parameter and running state of the secondary equipment, which can be implemented by a device model database matching mode, and is used to determine the function positioning of the equipment in the system. The position information refers to the physical installation position of the equipment in the transformer substation, which can be recorded by a GIS coordinate system, and is used to establish the corresponding relationship between the equipment and the physical space. The connection rule refers to the allowed communication protocol and interface standard between the equipment, which can be defined by IEC 61850 protocol, and is used to ensure the compliance of data interaction between the equipment. The signal transmission relationship refers to the data flow direction and logical dependency relationship between the equipment, which can be implemented by analyzing the virtual loop information in the SCD file, and is used to determine the influence range of the maintenance operation on the system. The correlation model refers to a structured data set integrating equipment attributes and interaction relationships, which can be stored by a graph database, and is used to support logical verification during generation of the operation ticket.

[0057] Specifically, after parsing the standard data, first, the configuration information such as the device model and port parameter is extracted, and the physical position of the equipment is determined in combination with the GIS coordinate. Then, according to the preset communication protocol rule, the logical connection topology between the equipment is established, such as the sampling value transmission link between the merging unit and the protection device. By analyzing the virtual terminal connection relationship in the SCD file, the signal transmission path and the associated equipment set are further determined. Finally, the equipment attributes, connection topology and signal dependency relationship are integrated into a structured model including function description, operation constraint and maintenance period, for example, the binding relationship between the value modification operation of the protection device and the state of the associated soft pressure plate.

[0058] Compared with the prior art, the existing method relies on manual analysis of the equipment connection relationship, and needs to check the signal transmission path through paper drawings, which has the problems of low efficiency and easy omission. The present scheme can complete the logical correlation between the equipment by automatically parsing the equipment configuration and virtual loop information, and avoid misjudgment of the topology relationship caused by manual operation.

[0059] Through the above technical scheme, the application can automatically identify the signal transmission dependency relationship between the secondary equipment, and ensure that all associated equipment safety measures are accurately covered during generation of the operation ticket. For example, when a certain intelligent terminal is disconnected, the maintenance pressure plate and the associated protection device that need to be operated synchronously can be automatically associated, so as to avoid the risk of misoperation of live equipment caused by human error.

[0060] In a specific embodiment, the correlation and signal transmission relationship of secondary equipment are sorted out based on expert experience. By classifying and organizing the secondary equipment of the substation and analyzing the logical relationship between the equipment, the signal transmission paths between the main transformer, circuit breaker, mutual inductor and other equipment are sorted out.

[0061] In an embodiment, the correlation refers to the logical or configurational association between secondary devices, such as the correlation between failure startup of line protection and bus protection. The signal transmission relationship is the embodiment of this correlation. For example, the failure startup correlation mentioned above is carried by the failure startup transmission information between line protection and bus protection.

[0062] The logical relationship is: in order for the transformer protection to complete its protection function, it is necessary to collect the circuit breaker positions and transformer electrical quantities on the three sides of the transformer, that is, the switch positions, transformer currents, and voltage values ​​of the circuit breakers on each side of the transformer, which need to be respectively provided to the transformer protection device through cable connections. In the scenario here, there is a logical relationship between the various devices.

[0063] In this specific embodiment, a correlation model is constructed using lines, transformers, busbars, busbar protection devices, and substation monitoring hosts. For each device type, its functional characteristics and control rules are analyzed in detail to establish a corresponding correlation model. For example, for a busbar protection device, the model includes its protection range, protection type, and action sequence.

[0064] Establish the physical connection relationships and virtual terminal loop models between devices. By analyzing the substation wiring diagram, establish the physical connection relationships between devices, including cable types and lengths. Simultaneously, construct a virtual terminal loop model to describe the electrical connection relationships between devices.

[0065] Step S003: Develop an equipment maintenance list through the association model, thereby generating a secondary operation ticket and a work ticket.

[0066] In a further embodiment, the equipment maintenance list is formulated through the association model to generate a secondary operation ticket and a work ticket: Formulate an operation rule library and a strategy library corresponding to the equipment according to the substation secondary operation library, wherein the strategy library includes an interval strategy library and a device strategy library; Develop a typical operation sequence library based on the secondary maintenance operation requirements in the operation rule library; By combining the real-time data with the operation sequence library, a secondary operation ticket is obtained; Generate operation content through the operation rule library and strategy library to obtain a work ticket.

[0067] In an embodiment, the operation rule library refers to a database storing device operation procedures, safety specifications, and maintenance requirements, and can be implemented in the form of a structured database or a knowledge graph, and is used to standardize operation procedures and constrain operation behaviors. The strategy library refers to a set of differentiated operation strategies set for different intervals or device types, and can be implemented by storing operation templates in different scenarios, such as an interval strategy library that can include operation steps corresponding to bus intervals and transformer intervals, and a device strategy library that can include operation contents corresponding to protection devices and measurement and control devices. The typical operation sequence library refers to a set of standardized operation steps generated based on historical operation data, and can be formed by extracting high-frequency operation sequences and optimizing the order by using a data mining algorithm, and is used to guide the generation of operation tickets.

[0068] Specifically, the establishment of the operation rule library and the strategy library depends on the device correlation and the functional model parsed in the substation secondary operation library. For example, the interval strategy library can generate corresponding operation step templates according to the connection relationship of devices in different intervals and the signal transmission path, and the device strategy library can generate corresponding maintenance content templates according to the device type and its function definition. In the process of formulating the typical operation sequence library, common operation steps can be extracted by analyzing historical operation records, and standardized operation procedures can be generated in combination with device priority scoring rules. When real-time data is combined with the operation sequence library, for example, the current device state parameters are matched with the condition rules in the sequence library, and the secondary operation ticket that meets the current working condition is dynamically generated. The generation of the work ticket is achieved by calling the operation template matched with the device type in the strategy library, and filling in the specific device parameters and operation content.

[0069] Compared with the prior art, the traditional method relies on manual experience to write operation tickets and work tickets, and has the problems of inconsistent process and easy omission of key steps. The present scheme avoids the subjective differences of manual judgment by dynamically matching and generating tickets combined with real-time data through the standardized definition of the rule library and the strategy library. For example, in the prior art, the operation sequence completely depends on the memory of the workers, while the present scheme provides standardized procedures through the typical operation sequence library to ensure the integrity and logical rationality of the operation steps.

[0070] Through the above technical solutions, the present application realizes the automatic generation of secondary operation tickets and work tickets, reduces the omissions or errors that may occur in the manual writing process, and improves the efficiency and accuracy of ticket generation. For example, in the device maintenance scenario, the system can automatically match the operation template in the interval strategy library, generate an operation ticket containing complete safety measures combined with real-time device status, and avoid the problems of missing or misplacing the pressure plate that may occur in traditional manual filling.

[0071] The embodiment further arranges the maintenance sequence of the secondary equipment through the operation sequence library, and the maintenance sequence is arranged by obtaining scores of the secondary equipment and then arranging the scores to obtain a maintenance priority list.

[0072] In the embodiment, the maintenance sequence arrangement refers to determining the sequence of maintenance operations according to the equipment state and operation requirements, and can be achieved by comprehensively evaluating indicators such as equipment importance, failure rate, and operation life, to solve the problems of low efficiency and strong subjectivity in traditional manual sorting. The score refers to a quantitative value reflecting the urgency of equipment maintenance, and can be obtained by using a weighted scoring model, for example, by using equipment importance coefficient, failure rate coefficient as input parameters, and achieving multi-dimensional evaluation through weight distribution. The priority list refers to a list of equipment maintenance sequences generated in descending order of scores, and can be achieved by sorting the score results in descending order through a sorting algorithm, to guide the reasonable allocation of maintenance resources.

[0073] In the embodiment, the maintenance priority list of the equipment is formulated. In the embodiment, the maintenance priority list of the equipment is formulated according to factors such as equipment importance and maintenance cost. The priority is calculated by using a weighted scoring method based on weights, wherein the weights include equipment importance coefficient, failure rate coefficient, and maintenance cost coefficient.

[0074] Specifically, when generating the maintenance priority list, first, the operation data of the equipment is extracted from the secondary operation library, such as equipment type, operation life, and historical failure times. Then, according to the preset scoring rules, the importance coefficient and the failure rate coefficient of each equipment are weighted and calculated, for example, the equipment importance weight is set to 0.5, the failure rate weight is set to 0.3, and the operation life weight is set to 0.2, and the comprehensive score is obtained by linear weighted summation. Finally, the score result is input into the sorting module, and the equipment maintenance list is generated in descending order, for example, the equipment with a score higher than 80 is automatically arranged in the top three of the list, to ensure that the key equipment obtains the maintenance resources in priority.

[0075] Compared with the prior art, the existing method relies on manual experience to determine the equipment maintenance sequence, and has the problems of strong subjectivity, low efficiency, and easy omission of key equipment. The present scheme can objectively evaluate the equipment maintenance priority by using a quantitative scoring model and an automatic sorting mechanism, avoid human error, and reduce the manual checking time, for example, in a substation containing hundreds of equipment, the priority of all the equipment in the substation can be sorted in a few seconds.

[0076] By the technical solution, the application realizes automatic generation of secondary equipment maintenance sequence, ensures that high importance or high failure risk equipment is arranged for maintenance in priority, and effectively prevents equipment operation abnormality caused by maintenance delay. Meanwhile, through the standardized scoring rule, subjective judgment difference of different operators is eliminated, and the scientificity and execution efficiency of the maintenance plan are improved.

[0077] Further, the application further comprises a step of obtaining the score of the secondary equipment. The priority score of the equipment is calculated by using the weighted scoring calculation formula, and the maintenance sequence of all the equipment is arranged according to the priority score to obtain a priority list. The weighted scoring calculation formula is: P = w1 × I + w2 × F + w3 × C Wherein, P is the priority score, I is the equipment importance coefficient, w1 is the equipment importance coefficient weight, F is the equipment importance coefficient, w2 is the equipment importance coefficient weight, C is the failure rate coefficient, and w3 is the failure rate coefficient weight.

[0078] In an embodiment, the equipment importance coefficient refers to the function criticality level of the equipment in the secondary system of the transformer substation, and can be quantitatively assigned by using the equipment type, the circuit level or the protection range, for example, the importance coefficient of the main transformer protection device can be higher than that of the ordinary line protection device. The equipment operation state coefficient refers to the current health state or performance degradation degree of the equipment, and can be realized by comprehensively evaluating parameters such as temperature, communication delay, and self-check alarm number in real-time monitoring data. The failure rate coefficient refers to the frequency of abnormality or defect in the historical operation of the equipment, and can be calculated according to the ratio of the failure number to the operation time length in the operation and maintenance record. The weight coefficients w1, w2 and w3 are used to adjust the influence degree of different evaluation dimensions on the total score, and can be pre-set by using the analytic hierarchy process or the expert experience method.

[0079] Specifically, when the equipment maintenance sequence needs to be made, the I, F and C parameter values of the target equipment are first extracted from the secondary operation library of the transformer substation, and the priority score of each equipment is calculated by substituting the weighted scoring formula. For example, the I value of a certain intelligent terminal equipment is 0.9 (corresponding to interval layer key equipment), the F value is 0.6 (there is slight communication delay), and the C value is 0.8 (there are two failures in the past year), and when the weights w1=0.5, w2=0.3 and w3=0.2, the score P=0.5×0.9+0.3×0.6+0.2×0.8=0.79. After the score of all the equipment is calculated, the maintenance priority list is generated in descending order, and it is ensured that the equipment with high score is arranged for maintenance resources in priority.

[0080] Compared with the prior art, the traditional method relies on artificial experience to subjectively sequence the equipment maintenance sequence, which is prone to cause key equipment not to be processed in priority due to differences in technical level of operation and maintenance personnel. The scheme quantifies evaluation indexes and mathematical models to fuse the importance of equipment, real-time state and historical failure data into objective scores, so that the formulation of the maintenance sequence is free from the limitations of artificial experience, and the decision-making deviation caused by a single evaluation dimension is avoided.

[0081] Through the above technical solutions, the application realizes automatic and intelligent sequencing of secondary equipment maintenance sequence, ensures that high importance and high risk equipment are given priority to obtain maintenance resources, effectively reduces the risk of equipment failure expansion caused by unreasonable maintenance sequence, and simultaneously adapts to the operation and maintenance strategy needs of different substations through flexible configuration of weight coefficients.

[0082] Step S004: Obtain the operation records of the secondary operation ticket and the work ticket, and perform safety verification on the operation records.

[0083] Further, the safety verification of the operation records is: According to the operation sequence, equipment selection and operation authority in the operation record data; Comparing the contents of the secondary operation ticket and the work ticket with the operation record data, if there is no difference, it is safe; if there is a difference, an alarm is issued.

[0084] Among them, the operation sequence in the operation record data refers to the execution order of the operation steps, which can be realized by time stamp marking or flow node recording, and is used to verify whether the operation flow conforms to the preset rules.

[0085] Among them, the equipment selection refers to the type and number of secondary equipment involved in the operation process, which can be matched through device identifiers or coding systems to ensure that the operation object is consistent with the content on the ticket.

[0086] Among them, the operation authority refers to the identity authentication and operation range of the operator, which can be verified by role permission database or digital certificate to avoid unauthorized operation.

[0087] Among them, no difference in comparison refers to the sequence, equipment and authority in the operation record being completely consistent with the information on the ticket, which can be realized by data verification algorithm or hash value comparison to confirm the operation compliance.

[0088] Among them, the alarm refers to triggering an alarm signal when there is a difference in comparison, which can be realized by sound and light prompt, message push or log marking method to prompt the abnormal state in time.

[0089] The operation sequence refers to the execution order of the operation steps, which can be implemented by a timestamp verification mechanism, and the execution time point of each operation step is recorded for sequence verification. The device selection refers to the specific device identification involved in the operation, which can be implemented by a device ID matching algorithm, and the device information is obtained by scanning the device two-dimensional code or reading the electronic tag. The operation permission refers to the authorization level of the operator, which can be implemented by querying the permission database, and the user identity authentication information is matched with the preset permission rules. The content comparison refers to data consistency verification, which can be implemented by a hash algorithm, and the hash values of the operation ticket and the operation record are generated for difference detection. The alarm mechanism refers to the notification of abnormal state, which can be implemented by system message pushing, and the warning signal is sent to the monitoring terminal through the preset communication interface.

[0090] Specifically, during the maintenance process of the substation, the system real-time collects the record data of the secondary operation ticket and the work ticket executed by the operator, including the time sequence of the operation steps, the device identifier, and the operator identity information. The standard operation sequence and the device list are obtained by analyzing the operation ticket file, and the actual execution information in the record data is matched item by item. When it is detected that the device selection is inconsistent with the list on the ticket, the operation step sequence is disordered, or the operator's permission is out of bounds, the system automatically triggers the alarm process. For example, when replacing the intelligent terminal, if the operation record shows that the maintenance pressure plate is not disconnected first as required on the ticket and the device is directly operated, the system will immediately suspend the subsequent operation and send an alarm information to the monitoring center.

[0091] Specifically, the operation record data is real-time obtained from the operation terminal or the monitoring system, containing the execution time of the operation step, the device identifier, and the operator information. The system compares the operation record with the generated secondary operation ticket and work ticket item by item, for example, by analyzing the device list, operation step sequence, and authorized personnel list on the ticket, and matching the actual execution data in the record. If all data items are consistent, it is determined to be a safe state; if there are inconsistent device numbers, disordered step sequences, or unauthorized operators, an alarm mechanism is triggered. The alarm information can be associated with the operation and maintenance management platform to generate an abnormal handling task and notify the relevant personnel to check.

[0092] Specifically, during operation execution, operation record data is collected in real time and stored in a database. The system generates a standardized verification template by parsing the preset operation sequence, device list, and permission requirements in the operation ticket. The actual execution data in the operation record is converted into the same data structure as the verification template, such as encapsulated in XML or JSON format. During comparison, the system checks whether the operation steps are completely executed, whether the device codes match, and whether the operator's permissions are compliant. If all fields are consistent, it is determined to be in a safe state; if there are missing steps, incorrect device codes, or permission out-of-bounds, an alarm signal is triggered. The alarm signal can be associated with the operation and maintenance management platform to generate an abnormal work order and notify relevant personnel for review.

[0093] In some embodiments, the verification of the operation sequence can incorporate timestamp information to verify whether the time interval of the operation steps meets the safety procedures; the verification of device selection can introduce a topology verification module to ensure the logical isolation of the operation device from other running devices; and the verification of operation permissions can integrate biometric technologies such as fingerprint or face authentication to enhance the reliability of identity verification.

[0094] Compared with the prior art, the traditional method relies on manual checking of paper operation tickets and on-site records, which has the risk of missed detection and misjudgment. The present solution realizes real-time monitoring and rapid response to abnormalities by establishing an automated verification mechanism. The prior art cannot effectively identify hidden problems such as virtual terminal operation errors, while the present solution can accurately identify safety hazards such as virtual loop configuration errors through dual verification of device identifiers and logical relationships.

[0095] Through the above technical solutions, the present application effectively solves the problem of safety precautions missing due to low efficiency of manual verification, ensuring that each operation meets the predetermined safety procedures. The automated comparison mechanism reduces the probability of human error, especially when dealing with virtual loop operations in intelligent substations, it can accurately identify device association errors and prevent cascading failures caused by misoperation. The abnormal alarm mechanism shortens the response time of safety hazards, providing real-time safety assurance for substation maintenance operations.
