Based on this, the simulation training system can monitor the user's simulation operation of the virtual device in the simulation training interface of the simulation training system, and write the corresponding input data into the data interaction area for the application program to read. The input data read is equivalent to the input data generated after the user performs the operation and inspection operation through the physical relay protection device, and the application program retains the complete relay protection logic and necessary functional modules of the relay protection device; thus, the application program can perform calculations through the input data to obtain the output data corresponding to the simulation operation, and the output data represents the operating state of the physical relay protection device after being operated. The application program writes the output data into the data interaction area, so that the simulation training system can display the operating state of the operated virtual device in the simulation training interface by reading the output data.

[0026] In the following description, specific details such as specific system structures, technologies, etc. are provided for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present application. However, it should be clear to those skilled in the art that the present application may also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to prevent unnecessary details from obstructing the description of the present application.

[0027] In the related art, the simulation training system of relay protection only simulates the appearance of the relay protection device, such as the shape, human-machine interface and menu display, but ignores the internal structure of the relay protection training simulation system, so that the training is limited to contact and understanding the relay protection device, and there is still a lack of operational training on the relay protection device, resulting in poor training results.

[0028] In order to solve this problem, this application further explored the real reason why the simulation of the training system is limited, and found that the reason why only the appearance is simulated is mainly because the developer of the traditional relay protection training system is not the manufacturer of the relay protection device, and the algorithm and code of the relay protection device are the trade secrets of the manufacturer of the relay protection device. Therefore, during the development process of the training system, it is difficult to achieve the linkage between the relay protection algorithm inside the relay protection device, the external input and the device output. The simulation and restoration of the relay protection device are relatively superficial, and cannot support the interactive operation process between the technicians and the physical relay protection device through the simulation training system.

[0029] Based on this discovery, this application proposes a simulation training method for relay protection, which can restore the working principle and function of the relay protection device through various virtual devices in the simulation training system under the premise of protecting the rights and interests of the manufacturers of the relay protection device, allowing technical personnel to perform interactive operation simulation through the simulation training system of relay protection, thereby effectively improving the training effect.

[0030] In some embodiments, in order to implement the simulation training method, the simulation training system may be modeled first. In order to make the technician's simulation training operation as close as possible to the technician's actual operation of the physical relay protection device, the modeling method cannot only stay on the appearance of the relay protection device, but can perform fine-grained modeling to restore the internal details of the relay protection device and the connection relationship between the components.

[0031] Specifically, the panel cabinet drawings and device resource data list of the relay protection device can be obtained, which are generally provided by the manufacturer of the relay protection device. Among them, the panel cabinet drawings may include the panel cabinet drawings including the cabinet structure diagram, the chassis wiring diagram, the terminal block wiring diagram, etc.; the device resource data list includes a list of the acquisition channels of the relay protection device (AC quantity, open input contacts, open output contacts, etc.), a connection relationship table between the panel cabinet terminals and the internal acquisition channels of the relay protection device, and the interactive data of the human-machine operation of the relay protection device (such as buttons, signal lights and LCD image data, etc.).

[0032] Based on the panel cabinet drawings and device resource data lists, fine-grained modeling can be performed, so that the virtual devices in the simulation training system can restore the internal details and functions of their physical devices as much as possible, providing support for in-depth simulation training. Through 3D modeling, virtual relay protection devices, virtual panel cabinets, and virtual relay protection testers can be constructed.

[0033] In addition to constructing a three-dimensional model, in order to enable the virtual relay protection device in the simulation training system to respond to the user's interactive operations, this application proposes a method for implementing simulation training: the simulation training system provides a three-dimensional simulation training interface for user operation, and the application program of the virtual relay protection device implements the relay protection algorithm. By establishing a data interaction mechanism between these two independent software systems, the interactive operation and display linkage of the virtual relay protection device in the simulation training interface of the simulation training system are realized, and the equipment details, working principles and device functions of various relay protection devices are accurately restored, providing users with a more realistic relay protection device simulation training environment.

[0034] In order to facilitate data interaction between the two systems, it is also necessary to determine the interactive data information of the two systems based on the device resource data list.

[0035] For example, the logic devices corresponding to the simulation training system are virtual panel cabinets and virtual relay protection testers, and the application program corresponds to the virtual relay protection device. The interactive data between these two independent software systems includes the data corresponding to each logic device. For details, please refer to Figure 1 .

[0036] In addition, in the related art, the training system can only simulate fixed models of relay protection devices, but the models of relay protection devices produced by different manufacturers are different. Therefore, the traditional relay protection training system also has the problem of poor expansion flexibility.

[0037] In this regard, different manufacturers can encapsulate the embedded system application (Application, APP) of the relay protection devices they produce to obtain application programs for different models of relay protection devices. At the same time, in the modeling process, a unified modeling method can be used to standardize the modeling of different models of relay protection devices. Specifically, models of relay protection devices of different models can be constructed in the simulation training system, and users can select the corresponding relay protection three-dimensional model for simulation training by model. Correspondingly, the simulation training system constructs data information for the interaction between different three-dimensional models and corresponding applications based on the model, so that the subsequent simulation system can allow the corresponding three-dimensional model and application to interact through the model. This method enables the simulation training system to have the expansion capability of flexibly accessing the application programs of simulated relay protection devices of different models from different manufacturers.

[0038] Based on the constructed simulation training system, the simulation training method for relay protection proposed in this application will be described below through specific embodiments.

[0039] The simulation training method for relay protection provided in the embodiment of the present application can be applied to the simulation training system for relay protection. The electronic device can be used for simulation training for technicians under the premise of being loaded with the simulation training system. The electronic device may include a mobile phone, a tablet computer, a vehicle-mounted device, an augmented reality (AR) / virtual reality (VR) device, a notebook computer, an ultra-mobile personal computer (UMPC), a netbook, a personal digital assistant (PDA), etc. The embodiment of the present application does not impose any restrictions on the specific type of the electronic device.

[0040] In order to illustrate the technical solution proposed in this application, each embodiment will be described below using a simulation training system for relay protection as an execution subject.

[0041] Figure 2 A schematic flow chart of a simulation training method for relay protection provided by the present application is shown, and the simulation training method for relay protection includes:

[0042] Step 210: After the simulation training system is started, the simulation training system constructs a data interaction area based on the interaction data information.

[0043] After the simulation training system is started, in order to facilitate interaction with the application, the data interaction area can be determined according to the interactive data information determined during the modeling process. The data interaction area can be used for data interaction between the two systems, creating conditions for the linkage of the user's simulation operation (equivalent to the external input of the relay protection device), the relay protection algorithm, and the display of the virtual device in the simulation training system (equivalent to the output of the relay protection device).

[0044] Step 220: The simulation training system writes the generated input data into the data interaction area in response to the user's simulation operation on the virtual device to be operated in the simulation training system.

[0045] The simulation training system can provide a simulation training interface based on the constructed three-dimensional model. In the simulation training interface, each three-dimensional model, that is, each virtual device, has the structure, components and functions of its physical device, so the real operation of the physical device can be simulated in the simulation training interface. For example, for the virtual panel cabinet, which is a virtual device to be operated, its terminals can also be plugged with cables (such as the current and voltage output by the relay protection tester are connected to the relay protection device); its input nodes can be toggled to show the switch status, knife switch position, etc.

[0046] Thus, in the simulation training interface, the simulation training system can monitor the user's simulation operation on the virtual device to be operated, such as connecting a certain cable to a certain terminal in the virtual screen cabinet, and generate corresponding input data. Among them, when the virtual relay protection tester is connected to the terminal block of the virtual screen cabinet with a cable, the simulation training system will convert the former into the cable connection relationship between the virtual relay protection tester and the virtual relay protection device according to the cable connection relationship between the terminal block of the virtual screen cabinet and the plug-in terminal of the virtual relay protection device, and use it as the input data of the application program of the virtual relay protection device. Therefore, after the cable is connected, the virtual relay protection device can present what state it switches from the existing state to, which needs to be determined based on the relay protection algorithm. Therefore, the simulation training system can first write the input data into the data interaction area. It can be understood that in addition to the input data corresponding to the operation of the simulation training interface, the data interaction area also includes the current output data of the virtual device to be operated, so that when displaying the simulation results, the corresponding animation effect can be presented, thereby further improving the simulation training to be closer to the actual operation.

[0047] For the input data written into the data interaction area, the application program of the virtual relay protection device can perform a reading operation to obtain the output data corresponding to the input data, and write the output data into the data interaction area so that the simulation training system can read and display it.

[0048] Step 230: The simulation training system reads output data corresponding to the input data from the data interaction area.

[0049] Step 240: Display the operation status of the virtual device to be operated in the simulation training interface of the simulation training system based on the output data.

[0050] The simulation training system can read the output data in the data interaction area and make the virtual device to be operated present the corresponding simulation animation according to the output data. For example, through a certain operation, the application writes the image data of the LCD screen, and the simulation training system reads the image data of the LCD screen and displays the image in the corresponding area of ​​the virtual screen cabinet.

[0051] In this embodiment, in order to simulate and restore the relay protection device in depth, the simulation training system can create a data interaction area to allow data interaction between two independently running systems, namely, the simulation training system and the application program of the relay protection device. Based on this, the technician can simulate the operation of the virtual device to be operated through the simulation training interface of the simulation training system. The simulation operation is similar to the real operation when the user operates the physical relay protection device. After the simulation data corresponding to the simulation operation is written into the data interaction area by the simulation training system, it can be read and run by the application program to obtain the output data of the state presented by the physical relay protection device after the simulation operation; after the output data is written into the data interaction area by the application program, it can be read by the simulation training system. The simulation training system can make the virtual device to be operated present the corresponding state according to the output data, thereby simulating the real state of the physical relay protection device after being operated. This simulation training method improves the depth of training, allowing technicians to simulate interactive operations through the simulation training system of relay protection, thereby effectively improving the training effect.

[0052] In some embodiments, to facilitate data interaction between two systems, step 210 specifically includes:

[0053] Step A1: creating different shared memory areas based on different logical devices in the interactive data information.

[0054] The simulation training system and the application program both have corresponding logical devices. Different logical devices have different outputs of related interactive data, and the objects available for reading the related interactive data are also different. Therefore, different logical devices may correspond to different shared memory areas, which mainly store the related interactive data of the corresponding logical device, and the data in the shared memory area are correspondingly provided with data writing objects and data reading objects. It can be understood that the data writing object of the shared memory area is the corresponding logical device.

[0055] Exemplarily, the simulation training system may create each shared memory area by calling the CreateFileMapping function of the Win32 API, thereby ensuring that the simulation training system can provide an independent and sharable memory area for each logical device.

[0056] After the shared memory area is constructed, in order to access the shared memory area associated with it, the application can open the mapping file of the shared memory area during the startup of the application to map the shared memory area to the process address of the application based on the mapping file.

[0057] Exemplarily, the application can open the mapping file by calling the OpenFileMapping function of the Win32 API, which enables the application to access the relevant shared memory area created by the simulation training system. In order to actually use the relevant shared memory area, the MapViewOfFile function can be called to map the shared memory area to the process address based on the mapping file, so that the application can interact with the simulation training system.

[0058] In this embodiment, based on the data interaction area constructed by the shared memory area, the simulation training system and the application can interact with each other through the shared memory, thereby avoiding data duplication and additional overhead in the traditional inter-process communication method, and improving the efficiency of interaction and communication.

[0059] In some embodiments, the logic device includes a virtual panel cabinet and a virtual tester corresponding to the simulation training system, and a virtual relay protection device corresponding to the application program. Figure 3 , Figure 3 The shared memory areas divided according to the logical devices are shown, including a first shared memory area corresponding to the virtual panel cabinet, a second shared memory area corresponding to the virtual tester, and a third shared memory area corresponding to the virtual relay protection device.

[0060] Among them, the data writing object and data reading object corresponding to the first shared memory area are the virtual panel cabinet and the virtual relay protection device, respectively, which are used to store the first interactive data corresponding to the virtual panel cabinet; the data writing object and data reading object corresponding to the second shared memory area are the virtual tester and the virtual relay protection device, respectively, which are used to store the second interactive data corresponding to the virtual tester; the data writing object and data reading object corresponding to the third shared memory area are the virtual relay protection device and the virtual panel cabinet / virtual tester, respectively, which are used to store the third interactive data corresponding to the virtual relay protection device.

[0061] As can be seen from the figure, for each shared memory area, data transmission is unidirectional, that is, the data write object corresponding to the shared memory area is only responsible for writing the corresponding data into the shared memory area, and is not involved in reading data; correspondingly, the corresponding data read object is only responsible for reading the objects stored in the shared memory area, and is not involved in writing data.

[0062] In this embodiment, a shared memory area is configured for each logic device to facilitate data exchange between the logic device and other logic devices, so that the two systems can break the independent state and realize the linkage between input-relay protection algorithm-output in the simulation training process, making the training more realistic.

[0063] In some embodiments, the application and the program of the simulation training system can be run on different electronic devices or on the same electronic device. If the application and the program of the simulation training system are run on different electronic devices, a new communication protocol needs to be developed separately, and the efficiency and stability of the data interaction process are inferior to running on the same electronic device. Therefore, in order to improve the efficiency and stability of data interaction between the two, it is preferred that the application and the simulation training system run on the same electronic device, so that efficient and stable data interaction can be achieved based only on the functions of the Win32 API interface, so as to improve the reliability of simulation training.

[0064] The application program has no visual graphical interface and runs silently in the background independently of the training simulation system. During operation, the corresponding data obtained by the operation is written into the data interaction area, which is read by the training simulation system and displayed in real time in the three-dimensional interface of the training system.

[0065] In some embodiments, during the simulation process, it is assumed that the technician changes the cable connection between the virtual panel cabinet and the virtual relay protection tester through the simulation training interface (the simulation training system can convert it into a cable connection from the virtual relay protection tester to the virtual relay protection device in the background). In order to achieve the docking of channel data, the virtual panel cabinet or the virtual relay protection tester can generate input data according to the connection operation of the cable connection in the simulation training interface. The input data is specifically a "channel mapping table", and the data is written into the first / second shared memory area in real time; the real-time operation status of the virtual panel cabinet (such as the insertion and withdrawal of the protection pressure plate, the status of the device panel buttons) or the real-time operation status of the virtual relay protection tester (such as test commands and test configurations) can also be written into the first / second shared memory area in real time.

[0066] The virtual relay protection device reads the input data in the first / second shared memory area, and based on the mapping relationship between the first / second shared memory area and the process address of the application, the application can perform operations based on the input data through the relay protection algorithm to output corresponding output data, such as the opening contacts of the relay protection device (such as tripping outlets, remote tripping contacts, reclosing, starting failure points, signal opening contacts, etc.), real-time image data of the LCD display screen of the relay protection device panel, and real-time output data such as LED signal lights of the relay protection device panel. These data will be written into the third shared memory area corresponding to the virtual relay protection device by the application, so as to be read by the virtual panel cabinet or the virtual relay protection tester, and then displayed on the simulation training interface, for example, the opening contact status of the tripping outlet of the virtual relay protection device will be displayed on the LCD interface of the virtual tester; the virtual panel cabinet will display the LCD image and signal lights of the virtual relay protection device on the device panel.

[0067] It should be understood that the size of the serial numbers of the steps in the above embodiments does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.
