Abstract
Description
Technical Field
[0001] This invention relates to the field of power system operation and maintenance training technology, and in particular to a teaching device based on an electronic simulation board for switching multiple operating states, applicable to simulating the operating state of a substation. Background Technology
[0002] Substation simulation boards are important equipment in power systems, used to simulate the operating status of substations, facilitating dispatchers' monitoring, debugging, and troubleshooting. Their development has gone through several stages, from early handmade simulation boards to modern digital and intelligent simulation boards.
[0003] Currently, most substation operation training still relies on simulated diagrams created by electronic equipment, which directly reflect data from the substation and lines. These simulated diagrams typically have alarm functions; when equipment malfunctions, the system can automatically match voice prompts and issue alarm signals. However, some manual operation is still required for these simulated diagrams, such as adjusting the positions of indicator lights on the screen. Summary of the Invention
[0004] The purpose of this invention is to overcome the problems of existing electronic simulation boards used for substation operation training, which require manual operation, have inconsistent equipment status with the actual site conditions, incomplete or simplified displays, data delays, and cannot quickly switch between multiple operating modes. This invention provides a teaching device based on an electronic simulation board for switching between multiple operating states. By setting up a board design module for constructing a simulation of substation lines and equipment, an association matching module for establishing their correspondence and logical association with actual site objects, a logic judgment module for building a process framework based on typical power grid work orders and performing logic verification, and a multi-operating mode module for controlling the switching of multiple teaching modes, this invention achieves the goals of rapid switching between multiple equipment states, operation logic verification, and adaptation to multiple teaching modes in substation operation training, ensuring consistency between equipment status and the actual site conditions, and improving training effectiveness.
[0005] The objective of this invention is achieved through the following technical solution: A teaching device based on an electronic simulation board with multiple operating states switching, comprising: The drawing board design module is used to build the lines and equipment of a simulated substation; The association matching module is used to establish the correspondence and logical association between the lines and equipment on the drawing board design module and the actual objects on site. The state switching module is used to switch between various operating states of the device and synchronize the state switching command to the logic judgment module; The logic judgment module is based on the workflow of a typical power grid work order to build a work task workflow framework, which is used to perform logical verification on line status changes, equipment status changes and operation steps on the drawing board design module. The multi-working-mode module is used to switch between different teaching modes and control the working mode and status of the association matching module and the logic judgment module according to different teaching modes. The association matching module, state switching module, logic judgment module, and multi-working mode module are all electrically connected to the drawing board design module.
[0006] Preferably, the drawing board design module includes a line display unit and an equipment display unit. The line display unit is used to display the lines of the simulated substation, and the equipment display unit is used to display the equipment of the simulated substation.
[0007] Preferably, the logic judgment module specifically includes a line judgment unit, an equipment judgment unit, and a step judgment unit. The line judgment unit is used to perform logical verification on the line status changes of the simulated substation on the drawing board design module, and to identify the rationality of line on / off and load distribution status. The equipment judgment unit is used to perform logical verification on the equipment status changes on the drawing board design module, and to verify the compatibility between the equipment status and the line status. The step judgment unit is used to perform logical verification on the operation steps of the operator on the drawing board design module, and to check the accuracy of the operation sequence and the operation object according to the process framework of the typical power grid work order.
[0008] Preferably, the line judgment unit is also used to verify the balance of line load distribution and overload risk, the equipment judgment unit is also used to verify the rationality of equipment operating parameters, and the step judgment unit is also used to check the completeness of operation steps.
[0009] Preferably, the line judgment unit, the device judgment unit, and the step judgment unit are interconnected. The line status change information obtained by the line judgment unit triggers the linkage verification of the device judgment unit, and the device status change obtained by the device judgment unit triggers the adaptability verification of the line judgment unit. The completeness and accuracy of the result executed by the step judgment unit are judged through the dual verification of the line judgment unit and the device judgment unit.
[0010] Preferably, the multi-working-mode module includes a teaching mode unit, a practice mode unit, an examination mode unit, and a control unit, which are switched via the control unit.
[0011] Preferably, the teaching mode unit includes a free teaching mode and a work-ticket teaching mode. In the free teaching mode, the logic judgment module is not active and the association matching module is not associated with the physical objects on site. In the work-ticket teaching mode, the logic judgment module is active and the association matching module is associated with the physical objects on site. When the practice mode unit is activated, the logic judgment module is active, the association matching module is not associated with the physical objects on site, and the correct steps are provided when the student makes a mistake. When the examination mode unit is activated, the logic judgment module is not active, and the association matching module is not associated with the physical objects on site.
[0012] As a preferred option, the teaching device based on the electronic simulation board with multiple operating states also includes a background management module, which is used to configure work orders, manage student information, issue examination tasks, and store operation records and examination results.
[0013] Preferably, the workflow framework of the logic judgment module is dynamically adjusted according to the updates of typical power grid work tickets.
[0014] The beneficial effects of this invention are as follows: through the coordinated cooperation and electrical connection design of the drawing board design module, the association matching module, the state switching module, the logic judgment module and the multi-working mode module, it realizes the rapid switching of multiple equipment states in substation operation training, the consistency and synchronization of equipment states with the actual on-site objects, the logical verification of operation steps, and the flexible adaptation of multiple teaching modes. It effectively solves the problems of high dependence on manual operation of existing simulation drawing boards and insufficient adaptability to training scenarios, and improves the accuracy and efficiency of operation and maintenance training.
[0015] Based on the process verification function of typical power grid work tickets and the full equipment and line association display of the association matching module, it ensures that no operation steps or risk points are omitted during the training process, avoids misjudgment and misoperation caused by incorrect information or simplified display, significantly reduces safety hazards in training, and enables trainees to fully master the logical association and operation specifications of equipment in the station.
[0016] The flexible switching of multiple working modes adapts to the needs of different training scenarios such as teaching, practice, and examination. Combined with the real-time synchronization of equipment status and operation feedback function, it not only improves the effectiveness of students' independent practice and the fairness of assessment, but also provides teachers with convenient training management tools. At the same time, it can also take into account the needs of on-site equipment operation and maintenance, and achieves a seamless connection between training and practical operation.

Figure 1 As shown, it includes: Drawing board design module 1 is used to construct the lines and equipment of a simulated substation; The association matching module 2 is used to establish the correspondence and logical association between the lines and equipment on the drawing board design module and the actual objects on site; The state switching module 3 is used to switch between various operating states of the equipment and synchronize the state switching instructions to the logic judgment module.

[0024] The drawing board design module includes a line display unit and an equipment display unit. The line display unit is used to display the lines of the simulated substation, and the equipment display unit is used to display the equipment of the simulated substation.
[0025] The logic judgment module specifically includes a line judgment unit, an equipment judgment unit, and a step judgment unit. The line judgment unit is used to perform logical verification on the line status changes of the simulated substation on the drawing board design module, and to identify the rationality of line on / off and load distribution status. The equipment judgment unit is used to perform logical verification on the equipment status changes on the drawing board design module, and to verify the compatibility between equipment status and line status. The step judgment unit is used to perform logical verification on the operation steps of the operator on the drawing board design module, and to check the accuracy of the operation sequence and operation objects according to the process framework of typical power grid work tickets.
[0026] The line judgment unit is also used to verify the balance of line load distribution and overload risk; the equipment judgment unit is also used to verify the rationality of equipment operating parameters; and the step judgment unit is also used to check the completeness of operation steps to avoid omissions.
[0027] The line judgment unit, device judgment unit, and step judgment unit are interconnected. The line status change information obtained by the line judgment unit triggers the linkage verification of the device judgment unit, and the device status change obtained by the device judgment unit triggers the adaptability verification of the line judgment unit. The completeness and accuracy of the result executed by the step judgment unit are judged by the dual verification of the line judgment unit and the device judgment unit.
[0028] The multi-working-mode module includes a teaching mode unit, a practice mode unit, an examination mode unit, and a control unit. The teaching mode unit, practice mode unit, and examination mode unit are switched through the control unit.
[0029] The teaching mode units include a free teaching mode and a work-ticket teaching mode.

[0031] The workflow framework of the logic judgment module is dynamically adjusted according to the updates of typical power grid work tickets, and supports the import of new types of work ticket workflows and automatic adaptation of logic verification rules.
[0032] Specific usage instructions are as follows: Figures 2-4 As shown, the logical judgment models used in the teaching mode, practice mode, and examination mode, as well as their linkage with the actual equipment on site, differ, and can be selected according to actual needs.
[0033] The teaching mode is primarily used for instructors to train students. In this mode, the device offers two options: free teaching and work order teaching. Free teaching allows for any operation or step on the simulation board without logical judgment; any changes to the board will not alter the equipment or wiring, posing no safety risks. Instructors can freely select the desired wiring and equipment, perform any operation on the board, and visually display the product appearance and specific components of the wiring and equipment, facilitating instruction. Work order teaching, on the other hand, involves logical judgment in the simulation board; any changes to the board will directly affect the equipment or wiring (for safety, the linkage between the device and field equipment and wiring can be manually disabled). Instructors must select a work order, and the device will initialize the board and field equipment accordingly. Instructors must strictly follow the work order procedure. The device will then strictly link with the field equipment and display the field equipment's status on the board. If an instructor makes an error during instruction, the device will not respond and will not trigger any linkage with the field equipment.
[0034] The practice mode is primarily for self-practice by trainees. In practice mode, the operations and steps on the simulated diagram will involve logical judgments, but any changes to the diagram will not alter the equipment or wiring, posing no safety risks (for a more realistic experience, the device can be linked to the actual equipment and wiring on-site, requiring supervision). Trainees can select the appropriate work order for practice based on their learning needs. If a trainee makes a mistake during practice, the system will prompt for the correct steps until the trainee performs the operation correctly before proceeding to the next step. After the trainee completes all the steps, the system will display the time spent on the entire process, allowing the trainee to summarize their self-practice. Once the trainee confirms completion of the current practice, they can choose to reset the current process, and the system will reset the electronic diagram according to the current work order process for re-practice; alternatively, they can choose to return and select a new work order for practice.
[0035] The exam mode is primarily used by teachers to examine students. In exam mode, the operations and steps on the simulated diagram will not involve logical judgments, and any changes to the diagram will not affect the equipment or wiring (although for a more realistic experience, the device can be linked to the actual equipment and wiring on-site, requiring supervision). Before entering exam mode, teachers must first set up the required exam work order in the backend management system, generate a new exam, and publish it. Students log in, enter their relevant information, and perform the work order procedures. The system records all student actions in real time. When a student considers the work order complete and submits it, the system compares the student's actions with the correct procedure, displays the student's time and score for that exam, and stores the score in the backend. After the current student finishes their exam, the next student can log in.

This application is intended to cover any variations, uses, or adaptations of this application that follow the general principles of this application and include common knowledge or customary techniques in the art not disclosed herein.
[0037] It should be understood that this application is not limited to the precise structure described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope. The scope of this application is limited only by the appended claims.
