The present application will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.
[0021] In the following, the technical solutions in the embodiments of the present application will be described clearly and completely with reference to the drawings in the embodiments of the present application.

[0022] A PLC-based multipurpose electrical practical training method and device are described below with reference to the accompanying drawings according to an embodiment of the present application.
[0023] Figure 1 A flowchart of a PLC-based multipurpose electrical practical training method according to an embodiment of the present application is shown in FIG. 1, which includes the following steps: Figure 1 S1, constructing a hardware architecture integrated with multiple specifications of PLCs, and adapting to diversified practical training requirements from simple control to complex system protection by selecting different models of PLC controllers; S2, configuring a digital signal processing module and an analog signal processing module, realizing bidirectional interaction of digital switching signals and analog operating parameters, and constructing a signal interaction network of a real industrial scene; S3, designing a human-computer interaction interface, integrating two functional modules of system simulation and practical training platform through a touch screen panel, and supporting parameter setting, state display and control logic simulation operation; S4, establishing a modularized software architecture, uniformly deploying submodules of generator-transformer group protection, line protection, bus protection and control system simulation, and reserving standardized hardware interfaces and software expansion space to support function iteration; S5, introducing virtual simulation technology to expand system simulation modules, and realizing immersive practical training operation of equipment disassembly, wiring and debugging by establishing a three-dimensional model of the equipment combined with a PLC control program.
[0024] A PLC-based multipurpose electrical practical training method according to an embodiment of the present application is described in detail below with reference to the accompanying drawings.
[0025] The present application is based on PLC technology, constructs a multipurpose simulation platform, covers two parts of hardware architecture and software design, realizes three core functions of system simulation, practical training and research and development, and the specific scheme is as follows: The hardware architecture is shown in FIG. 2. Figure 2 As shown, the core control unit (Siemens series PLC) is connected with the signal processing module (DI / DO module, AI / AO module), human-computer interaction unit (Siemens touch screen), and auxiliary elements (indicator light, intermediate relay) through corresponding communication lines or signal lines. Among them, the DI / DO module and AI / AO module are connected with external analog signal source or execution element to realize signal input and output; the indicator light and intermediate relay are connected with the output terminal of the PLC to receive the control signal of the PLC and act.
[0026] Core control unit: Siemens series PLC is selected as the core, including Siemens S7-1200 (small PLC), S7-300 (medium-sized PLC), and S7-400 (large PLC). Among them, S7-1200 meets the simulation needs of most small control systems, S7-300 and S7-400 can cope with more complex and large-scale control logic simulation, such as multi-device linkage generator-transformer control system, to ensure that the needs of different complexity simulation scenarios can be met.
[0027] Signal processing module: equipped with DI / DO module (digital input and output) and AI / AO module (analog signal acquisition and output). The DI / DO module is used to receive external switch signals (such as button, switch state) and output control signals (such as relay action signal), to realize signal interaction with external analog devices; the AI / AO module can collect analog signal (such as voltage, current) and output analog control signal, which is used to simulate the running parameter changes of actual devices, such as voltage and current fluctuations of the generator, to ensure the authenticity of the simulation.
[0028] Human-computer interaction unit: Siemens series touch screen panel is used as the window for operators to interact with the simulation platform. Through the touch screen, function module selection, parameter setting, state viewing, and other operations can be realized, the interface is intuitive and easy to operate, simulates the use experience of the actual operation panel in the field, and reduces the learning cost of the operators.
[0029] Auxiliary elements: including indicator light and intermediate relay. The indicator light is used to visually display device running state, fault alarm, and other information, such as tripping state and normal running state in the generator protection; the intermediate relay is selected from the updated and eliminated Omron intermediate relay in the factory, which realizes signal amplification, control circuit conversion, and other functions, reduces hardware cost, improves resource utilization, meets the needs of energy conservation and environmental protection and cost control.
[0030] Software design as follows Figure 3The layout of the main interface of the software is shown, the positions of the two function buttons of "system simulation" and "training platform" are marked, and the required operation can be quickly located; then the function module switching logic is presented in the form of a flowchart. Starting from the main interface, click the "training platform" button to enter the relay protection training platform interface. This interface can select sub-modules such as generator-transformer group protection, line protection, etc. Each sub-module has the function of returning to the upper level interface, which can return to the relay protection training platform interface or the main interface, realizing the switching between different protection modules for the operator; click the "system simulation" button to enter the system simulation interface. This interface can select sub-modules such as control system (diesel generator control system, main transformer cooling control system), logic control, discrete control, process control, etc. Each sub-module can return to the system simulation interface or the main interface, clearly showing the operator's operation path. Figure 4
[0031] Development platform: Based on the TIA Portal (Boto) software development platform, which integrates SIMATIC STEP7, WinCC, SINAMICS driver and other software, the integration of programming, configuration and picture making is realized. There is no need to switch between multiple software, which improves the development efficiency, and the compatibility of each software module is good, reducing the probability of system errors.
[0032] Main interface design: The main interface of the software contains two function entrances of "system simulation" and "training platform". The operator can enter the corresponding function module through the corresponding button on the touch screen. The interface layout is clear, the function area is clear, and the required operation can be quickly located.
[0033] Training platform module: This module contains sub-modules such as generator-transformer group protection, line protection, bus protection, 6kV protection and 400V protection commonly seen in the factory. Taking the generator protection sub-module as an example, it integrates multiple protection verification functions such as generator differential protection, negative sequence overload protection and power protection, and also has the function of checking device parameters. The operator can check the device parameters on the interface according to the verification items, and set the function soft pad, hard pad and control word. Figure 5 As shown in the generator power protection interface, the left red area is set with indicator lights to display the current state information such as running, alarm and tripping; the upper right green area is designed with active power, tripping control word setting window and required input indication for protection; the lower right yellow area is set with voltage and current setting window for the operator to input different parameters for verification practice, simulating the complete process of actual protection verification. In addition, each sub-module has the function of returning to the upper level interface, which facilitates the switching between different protection modules for the operator.
[0034] System simulation module: this module includes the plant part control system (such as diesel generator control system, main transformer cooling control system) and the training teaching practice function of common control loop (such as star-delta starting, forward and reverse control, temperature control PID control, forward and reverse control, etc.). Taking the diesel generator control system as an example, all functions (such as sound and light alarm, interlocking selection, voltage display, working mode selection, start / stop / reset / emergency stop button operation, etc.) on the operation panel of the field control cabinet are transplanted to the touch screen interface, and the control program in the PLC is completely consistent with the actual control program in the field. The operator can simulate the actual control logic in the field through the touch screen interface, such as simulating the start, grid connection and load test of the diesel generator set, and observing the response state of the system; if subsequent optimization of the field diesel generator control program is required, debugging can be performed in this simulation module first, and the feasibility and stability of the program are verified before being applied to the field equipment, reducing the risk and cost of field debugging. At the same time, this module supports the subsequent addition of new simulation systems according to the planning, and has good expansibility.
[0035] The application can also have the following embodiments: Hardware core control unit alternative: in addition to Siemens series PLC, other mainstream brands of PLC such as Mitsubishi and Rockwell can be selected. For example, Mitsubishi FX series PLC (small), Q series PLC (medium and large), which has similar logic control, data processing and communication functions, can meet the core control requirements of the simulation platform. But need to adjust the software development platform (such as using Mitsubishi's GX Works series software) and hardware wiring mode accordingly, to ensure compatibility with other modules (such as signal processing module, touch screen), the overall function implementation logic is consistent with the original scheme, only the hardware brand and software tools are different.
[0036] Human-computer interaction unit alternative: in addition to Siemens touch screen, touch screens of brands such as Kunlun Tongtai and Weilun Tong can be used. These brands of touch screens also have good human-computer interaction functions, support picture configuration, parameter setting, state display and other operations, and can communicate with mainstream PLCs through standard communication protocols (such as Modbus, Profinet, etc.). In software design, the interface should be made and the program should be written according to the configuration software of the selected touch screen (such as Kunlun Tongtai's MCGS, Weilun Tong's EBPro), the interface layout and function logic can refer to the original scheme, to ensure the consistency of the user experience and operation process of the operator.
[0037] System simulation module expansion alternative: based on the existing system simulation module, virtual simulation technology can be introduced, a three-dimensional model of the device is established, combined with the PLC control program, to realize more intuitive, immersive simulation experience. The operator can disassemble, wire, debug and other operations through the virtual scene, further improve the authenticity and interest of the training. This alternative needs to increase the development or purchase cost of virtual simulation software, and the corresponding hardware (such as computer, virtual reality equipment) support, but it can expand more training scenarios on the basis of the original PLC control logic, which is suitable for scenarios with higher requirements for training experience.
[0038] To achieve the above embodiments, as shown in Figure 6 The embodiment also provides a multi-purpose electrical training device based on PLC 10, which comprises a multi-specification PLC integrated module 100, a digital and analog signal interaction module 200, a touch screen function integrated module 300, a modular software deployment module 400 and a virtual simulation module 500.
