Description

Technical Field

[0001] This invention relates to the field of power system automation technology, and in particular to a method and system for intelligent monitoring of equipment status based on structured electronic operation tickets, which can be applied to status monitoring scenarios of industrial equipment such as substations and power plants. Background Technology

[0002] In the power system sector, equipment status monitoring is typically conducted through computer monitoring systems or manual on-site inspections, with changes in equipment status usually based on the execution of operation tickets. Currently, some power plants have begun using standard electronic operation tickets; however, existing technologies do not integrate standard electronic operation tickets with equipment status monitoring sufficiently, failing to achieve intelligent status monitoring and automatic alerts, and thus failing to meet the demands for real-time equipment monitoring and intelligent management.

[0003] Furthermore, for equipment not connected to the computer monitoring system, and for equipment whose monitoring system channels are interrupted due to power outages during maintenance, there are significant difficulties in collecting its status, which further limits the comprehensiveness and effectiveness of equipment status monitoring.

[0004] Therefore, there is an urgent need for a more intelligent and efficient method for monitoring equipment status that can solve the problem of collecting status data for special equipment. Summary of the Invention

[0005] To address the aforementioned issues, this invention proposes an intelligent equipment status monitoring method and system based on structured electronic operation tickets. Utilizing the KKS (Kraftwerk-Kennzeichen System, power plant identification system) coding system, which assigns a unique identifier to each piece of equipment in the entire plant, a structured electronic operation ticket consisting of "instruction + equipment" is constructed. During the execution of the operation ticket, the system automatically acquires information on changes in equipment status by identifying the "instruction + equipment" information within the operation item. This achieves intelligent and automated monitoring of equipment status, improving the efficiency and accuracy of equipment management. Simultaneously, it effectively solves the problem of status acquisition for equipment not connected to a computer monitoring system or for equipment whose power supply to the monitoring system is interrupted due to maintenance, enabling comprehensive monitoring of equipment status.

[0006] The technical solution adopted in this invention is as follows: A method for intelligent monitoring of equipment status based on structured electronic operation tickets includes: Construct a device library and an instruction library, wherein the device library stores basic device information and the instruction library stores standardized operating instructions; Retrieve the devices and instructions corresponding to the operation items in the structured electronic operation ticket, and match them with the device library and instruction library; execute the operation items on the corresponding devices according to the matching results, and update the device status information in real time.

[0007] Further, the step of obtaining the devices and instructions corresponding to the operation items in the structured electronic operation ticket and matching them with the device library and instruction library includes: Extract equipment name keywords from the operation items of the structured electronic operation ticket and match them with the equipment names in the equipment database. After a successful match is made, the instruction keywords in the operation item are matched a second time with the instructions in the instruction library.

[0008] Furthermore, the step of performing operation items on the corresponding device based on the matching results and updating the device status information in real time includes: continuously comparing the current status of the device with the previous status, updating the previous status, the current status and the status change flag, recording the number of status changes, calculating the status duration, and providing status confirmation reminders.

[0009] Furthermore, the device database stores basic device information including the device's unique identifier name, KKS code, and installation location.

[0010] Furthermore, the device status information includes the current status, the previous status, the status change flag, the status change time, the number of status changes, and the status duration.

[0011] Furthermore, it also includes intelligent reminders and interactive feedback: when the device status changes, the font color of the corresponding device information in the human-computer interaction interface will automatically change and flash; by clicking on the device information, you can view the status change record, including time, comparison of the status before and after, and analysis of the reasons for the status change.

[0012] Furthermore, it also includes intelligent linkage and functional expansion: combining equipment status with the security measures of structured electronic operation tickets, and combining equipment status with the security measures of work tickets.

[0013] Furthermore, the security measures for combining equipment status with structured electronic operation tickets include: automatically generating electronic operation tickets that comply with security specifications based on the real-time status of the equipment, generating corresponding operation procedures, and conducting risk assessments on the operation procedures.

[0014] Furthermore, the integration of equipment status with work permit security measures includes: linking equipment status with work permit security measures, and automatically verifying whether the equipment status meets the security measure requirements before the work permit is processed.

[0015] A smart equipment status monitoring system based on structured electronic operation tickets includes: The equipment library stores basic equipment information; The instruction library stores standardized operating instructions; The intelligent monitoring module is configured to acquire the devices and instructions corresponding to the operation items in the structured electronic operation ticket, and match them with the device library and instruction library; execute the operation items on the corresponding devices according to the matching results, and update the device status information in real time.

[0016] The beneficial effects of this invention are as follows: (1) This invention combines structured electronic operation tickets with equipment status monitoring, realizing intelligent and automated monitoring of equipment status and improving the efficiency and accuracy of equipment status monitoring. By establishing a synchronous relationship between the operation items of the structured electronic operation ticket and the equipment status database, the equipment status is synchronously converted during the execution of the operation ticket. This effectively realizes the status collection of equipment not connected to the computer monitoring system or equipment whose power supply to the monitoring system is interrupted due to maintenance. This fills the gap in the traditional monitoring method for collecting the status of these special equipment and greatly improves the comprehensiveness of equipment status monitoring.

[0017] (2) Real-time intelligent monitoring of equipment status is achieved through the equipment status database. When generating new structured electronic operation tickets in the future, the equipment status is automatically and intelligently verified to ensure that the structured electronic operation tickets are consistent with the actual status of the equipment on site.

[0018] (3) By automatically identifying and obtaining changes in equipment status within the operation items, manual intervention is reduced, and the probability of human error is lowered. This provides a more comprehensive and intelligent solution for equipment management, which helps to improve the security and stability of the entire system. Attached Figure Description

[0020] To provide a clearer understanding of the technical features, objectives, and effects of the present invention, specific embodiments are now described. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention; that is, the described embodiments are only a part of the embodiments of the invention, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0021] Example 1 This embodiment provides a method for intelligent monitoring of equipment status based on structured electronic operation tickets, including: constructing an equipment library and an instruction library, wherein the equipment library stores basic equipment information and the instruction library stores standardized operation instructions; obtaining the equipment and instructions corresponding to the operation items in the structured electronic operation ticket and matching them with the equipment library and instruction library; executing the operation item content on the corresponding equipment according to the matching result and updating the equipment status information in real time.

[0022] Preferably, the process involves obtaining the equipment and instructions corresponding to the operation items in the structured electronic operation ticket and matching them with the equipment library and instruction library. This includes: extracting equipment name keywords from the operation items in the structured electronic operation ticket and matching them with the equipment names in the equipment library once; and after a successful match, matching the instruction keywords in the operation items with the instructions in the instruction library a second time.

[0023] Preferably, the operation items are executed on the corresponding devices according to the matching results, and the device status information is updated in real time, including: continuously comparing the current status of the device with the previous status, updating the previous status, the current status and the status change flag, recording the number of status changes, calculating the status duration, and providing status confirmation reminders.

[0024] Preferably, the basic equipment information stored in the equipment library includes the equipment's unique identifier name, KKS code, and installation location; the equipment status information includes the current status, the previous status, status change flag, status change time, number of status changes, and status duration.

[0025] Preferably, the method in this embodiment also includes intelligent reminders and interactive feedback: when the device status changes, the font color of the corresponding device information in the human-computer interaction interface is automatically changed (e.g., highlighted in red) and flashed to attract attention; the operator can view the status change record by clicking on the device information, such as time, comparison of the status before and after, and analysis of the reasons for the status change (combined with historical data and operation records).

[0026] Preferably, the method in this embodiment further includes intelligent linkage and functional expansion: combining equipment status with the security measures of structured electronic operation tickets, and combining equipment status with the security measures of work tickets. Specifically, based on the real-time status of the equipment, electronic operation tickets that comply with safety specifications can be automatically generated, and corresponding operation procedures can be generated, and risk assessments can be performed on the operation procedures; the equipment status can be linked with the security measures of work tickets, and the equipment status can be automatically checked to ensure that it meets the security requirements before the work ticket is processed.

[0027] Example 2 This embodiment is based on embodiment 1: This embodiment provides a method for intelligent monitoring of equipment status based on structured electronic operation tickets, including: constructing an equipment library and an instruction library, wherein the equipment library stores basic equipment information and the instruction library stores standardized operation instructions; obtaining the equipment and instructions corresponding to the operation items in the structured electronic operation ticket and matching them with the equipment library and instruction library; executing the operation item content on the corresponding equipment according to the matching result and updating the equipment status information in real time.

[0028] The specific descriptions of the device library, instruction library, and operation items are as follows.

[0029] Equipment Library: Stores basic equipment information (such as unique equipment identifier name, KKS code, installation location, etc.), for example: 500kV circuit breaker 5011, fire water supply electric valve DF206.

[0030] Instruction library: Stores standardized operation instructions, such as: close, disconnect, fully open, and fully close.

[0031] Operation Item: A standardized operation unit consisting of "instruction + equipment". Through the combination of equipment and instructions, it clearly expresses the specific operation requirements for a particular piece of equipment. Example: "[Close] <500kV circuit breaker 5011>" (the part in 【】 is the instruction: "Close", and the part in <> is the equipment: "500kV circuit breaker 5011").

[0032] This embodiment, based on the corresponding equipment and instruction libraries of structured electronic operation tickets, comprehensively organizes the plant equipment to generate an intelligent equipment status monitoring system. This system includes the following fields: equipment name and number, current status (e.g., "closed," "open," "fully open," "fully closed"), previous status, status change flag (yes / no), and change time. Specifically, the unique equipment identifier name and KKS code are used to uniquely identify each piece of equipment; the current equipment status reflects the equipment's current operating condition in real time; the previous status records the equipment's previous state for comparison; whether the status has changed is determined based on the comparison between the current and previous statuses; and the change time is the time when the equipment status changed.

[0033] Specifically, such as Figure 1 As shown, the method in this embodiment can be implemented using the following steps: Step 1: Building the underlying data for the intelligent equipment status monitoring system (1) Input: Equipment library data of structured electronic operation tickets.

[0034] (2) Processing: • Referencing the corresponding equipment and instruction libraries of structured electronic operation tickets, conduct a comprehensive review of all equipment in the plant to construct the underlying data for the intelligent equipment status monitoring system. The intelligent equipment status monitoring system stores the following information: equipment name, equipment number, current status (e.g., "closed", "open", "fully open", "fully closed"), previous status, status change flag (yes / no), and change time.

[0035] (3) Output: Low-level data of the intelligent equipment status monitoring system.

[0036] Step 2: Activate intelligent status monitoring (1) The user clicks the “Start Monitoring” button on the equipment status intelligent monitoring system interface and selects the corresponding structured electronic operation ticket.

[0037] (2) Processing: • Real-time acquisition of the execution process of the corresponding structured electronic operation ticket operation items and acquisition of the real-time status data of the corresponding equipment; • Automatically acquires the device and instruction corresponding to the operation item, and updates the device name, current status, previous status, status change flag (yes / no), and change time in real time within the device status intelligent monitoring system based on the execution status of the operation item. Operation item example: "[Close] <500kV circuit breaker 5011>" ([] represents the instruction: "Close", and <> represents the device: "500kV circuit breaker 5011").

[0038] Step 3: Status Change Recognition and Alerts (1) Processing: • Compare the current state with the previous state: • If inconsistent: Update "Previous Status" to the original current status, "Current Status" to the new status, and set "Status Change Flag" to "Yes"; automatically issue a reminder: "The status of this device has changed, please pay attention."

[0039] If consistent: Issue a reminder: "The status of this device has not changed. Please confirm."

[0040] (2) Output: Status reminder information.

[0041] Step 4: Interactive Feedback After State Change (1) Triggering condition: The state change flag is "yes".

[0042] (2) Processing: • In the intelligent device status monitoring system interface, the font color of the corresponding device information automatically changes (e.g., highlighted in red) to prompt the user to pay attention.

[0043] • Users can view detailed status change records (time, comparison of status before and after, etc.).

[0044] Furthermore, equipment status can be deeply integrated with structured electronic operation tickets and work permit security measures. Preferably, based on the real-time equipment status, electronic operation tickets conforming to safety specifications are automatically generated, corresponding operation procedures are created, and risk assessments are performed on the operation procedures. The equipment status is linked to the security measures of the work permit; before the work permit is processed, the system automatically verifies whether the equipment status meets the safety requirements.

[0045] Example 3 This embodiment is based on embodiment 1: This embodiment provides an intelligent equipment status monitoring system based on structured electronic operation tickets, including: The equipment library stores basic equipment information; The instruction library stores standardized operating instructions; The intelligent monitoring module is configured to acquire the devices and instructions corresponding to the operation items in the structured electronic operation ticket, and match them with the device library and instruction library; execute the operation items on the corresponding devices according to the matching results, and update the device status information in real time.

[0046] In summary, the intelligent equipment status monitoring method and system of the present invention have the following characteristics: 1. Equipment status monitoring based on structured electronic operation tickets This is the core technical mechanism of the present invention. By structurally analyzing the operation items of the operation ticket, a standardized "instruction + equipment" operation unit is formed. The equipment status database directly identifies and obtains the equipment status change information within the operation item, achieving seamless connection between the operation process and status supervision, effectively improving the real-time performance and accuracy of supervision, and realizing automated supervision of equipment status.

[0047] 2. Intelligent verification of equipment status when operation tickets are generated. When generating new structured electronic operation tickets, the actual equipment status is automatically and intelligently verified based on the equipment status stored in the equipment status database to ensure that the structured electronic operation tickets match the actual on-site equipment status and further ensure that the operation process complies with safety regulations.

[0048] 3. Real-time dynamic monitoring of equipment status and tracking of status changes. The device status database covers key fields such as device name, current status, previous status, status change flag, and change time. By comparing the current status with the previous status, it identifies status changes in real time, automatically marks status changes, and records the change time, thus forming a complete status change log. Through automated status identification and alerts, the workload of manual on-site inspections is significantly reduced, the possibility of human error is lowered, and maintenance personnel can respond to device status changes in a timely manner.
