DETAILED DESCRIPTION

[0015] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is described in detail in a clear and complete manner in conjunction with the accompanying drawings and embodiments.

[0016] The concept of the present invention is that it includes a process control module, a tool control module and an interactive control module; the process control module includes a component disassembly sub-process and a component judgment sub-process. For each component of the motor three-dimensional model disassembled in the component disassembly sub-process, it is necessary to enter the component judgment sub-process for judgment, and after the component judgment is completed, the next component is disassembled; the tool control module is used to provide a variety of disassembly tools for the component disassembly sub-process for students to choose; the interactive control module is used to realize the human-computer interaction function in the disassembly process.

[0017] Device Example: refer to Figure 1The schematic diagram of the software module of the motor drag training platform based on human-computer interaction mainly includes a memory database and a motor virtual disassembly program. Among them, the motor virtual disassembly program is the core theme of the entire motor drag training device based on human-computer interaction, which mainly includes an interactive control module, a tool control module and a process control module. The interactive control module is used to realize the human-computer interaction function in the disassembly process, such as interactive components can be highlighted (mouse floating components are highlighted), using tools to click on components for disassembly, etc.; interactive triggering and interactive performance are performed according to the tool type, and the interactive results are displayed; the tool control module is used to provide a variety of disassembly tools for the component disassembly sub-process for students to choose, such as screwdrivers, circlip pliers, rubber hammers, etc. In addition, the module also contains the model making standards of the tools, which are used to formulate the tools used to disassemble the virtual motor according to the formulated standards; the process control module is used to control the disassembly of the motor three-dimensional model (hereinafter referred to as the virtual motor) according to the disassembly process set by the motor disassembly process standard. The disassembly process includes a component disassembly sub-process and a component judgment sub-process.

[0018] Specifically, the disassembly sub-process in the process control module is used to select corresponding tools to disassemble the corresponding components of the motor three-dimensional model according to the motor disassembly process standards. After completing the disassembly of one component, the component disassembly sub-process enters the component judgment sub-process for students to judge the disassembled components. After the component judgment sub-process ends, it returns to the component disassembly sub-process to disassemble the next component until the disassembly task is completed.

[0019] The component disassembly flow chart of this embodiment is as follows Figure 2 As shown in the figure, the disassembly sequence is: motor hood, cooling fan, front cover, rear cover, rotor, front and rear seals and bearings, stator. The specific disassembly process is as follows: Enter the disassembly interface provided by the component disassembly sub-process (such as Figure 3 As shown, the interface includes a tool selection interface and a deduction record bar interface), first disassemble the motor hood, and the tool control module provides a tool selection interface for the trainee to choose to disassemble the motor hood. When the tool selected by the trainee is a cross screwdriver, the component disassembly sub-process disassembles the motor hood. After the motor hood is disassembled, it enters the component judgment sub-process. The component judgment sub-process provides a component judgment interface for the trainee to judge whether the motor hood is normal or damaged. After the judgment is completed, the disassembly interface is entered to continue to call the component disassembly sub-process to disassemble the cooling fan. During the disassembly process of this component, when the tool selected by the trainee is a circlip pliers, the component disassembly sub-process disassembles the cooling fan. After the cooling fan is disassembled, it enters the component judgment sub-process. The component judgment sub-process provides a component judgment interface for the trainee to judge whether the cooling fan is normal or damaged. After the judgment is completed, the disassembly interface is entered to continue to disassemble the front cover, the rear cover, the rotor, etc. The disassembly process is consistent with the above process and will not be repeated here.

[0020] It should be noted that if the trainees do not select the correct tools according to the disassembly process standards during the disassembly process, the disassembly of the corresponding components cannot be completed. For example, when selecting the disassembly tool for the motor hood, if the cross screwdriver is not selected, the motor hood cannot be disassembled; if the disassembled component is not judged, the next component cannot be disassembled. For example, if the disassembled motor hood is not judged, it is impossible to enter the disassembly interface to disassemble the cooling fan; in addition, the scoring module in the training device will record the trainees' incorrect operations in the deduction record column and deduct points to remind trainees to use tools correctly and disassemble the virtual motor according to the correct disassembly and judgment steps, helping trainees to develop good inspection habits in future work, avoiding the problem of parts being damaged without being discovered due to unfamiliarity with the disassembly process or improper operation, leaving safety hazards for subsequent power-on after assembly.

[0021] In addition, in the component judgment sub-process, the component failure can be set for the virtual motor component through the component control module of the training device, including "randomly selecting faults" or "manually selecting faults", which increases the flexibility of use and greatly improves the trainees' participation and ability to analyze and troubleshoot faults. The component failure types and phenomena set by the component control module are combined with the situations that often occur in actual use, covering most motor failure types. The fault library is rich in content and the failure phenomena are realistic, including button failures: SB1 failure, SB2 failure, SB3 failure; main contact failure: KM1 main contact failure, KM2 main contact failure, FR main contact failure; auxiliary contact failure: KM1 auxiliary contact failure, KM2 auxiliary contact failure, FR auxiliary contact failure; circuit breaker (QS) failure; fan side bearing failure, fan side end cover failure, cooling fan failure, wind hood damage; end cover failure; bearing failure; rotor failure; stator failure.

[0022] The component control module also includes component model making standards, which are used to formulate components of the motor three-dimensional model according to the formulated standards, such as formulating the motor fan cover, stator, rotor, etc. according to the formulated standards.

[0023] In order to help students understand motor performance, the motor dragging training device based on human-computer interaction also includes a motor performance fault simulation module, which is used to set performance faults for virtual motors, map the terminals of the motor junction box to the virtual motor measurement box, and set random faults of virtual motors through system software. Specifically, the fault setting process is as follows: Figure 4 As shown, the system software runs in the industrial computer, and the computer communicates with the simulated motor signal simulation box through RS485 communication to set the fault.

[0024] The motor faults that can be set in this module are as follows: ① Button failure; ② Circuit breaker failure; ③ Fuse failure; ④ The main contact of the contactor is faulty; ⑤ Contactor coil failure; ⑥ Auxiliary contact failure; ⑦ Thermal relay failure; ⑧ Three-phase motor insulation fault (phase-to-phase insulation and insulation to ground): UV phase insulation resistance fault, UW phase insulation resistance fault, WV phase insulation resistance fault and U / V / W-ground insulation resistance fault; ⑨ Three-phase resistance unbalance fault of three-phase motor: resistance fault of U-phase winding, resistance fault of V-phase winding, resistance fault of W-phase winding.

[0025] During the performance measurement process, the module is connected to the motor junction box through a signal line. The motor junction box provides a line for measurement connection, and all measurements are completed on the motor junction box.

[0026] For example, when measuring DC resistance and insulation resistance, the DC resistance and insulation resistance of the virtual motor are set through the system software to simulate motor failure, and then the students perform performance measurements. Specifically, during the measurement process, the students use a multimeter to measure the DC resistance of the motor (the resistance of each phase winding of the motor), and calculate the balance of the motor winding to determine whether the motor is burned out; use a hand-cranked megohmmeter to measure the insulation resistance (the resistance of the motor between phases and the phase-to-ground winding) to determine whether the insulation of the motor meets the standards; fill in the measurement and calculation results in the corresponding columns to determine whether the motor quality is qualified.

[0027] When measuring the control circuit, all the device contacts involved in the motor forward and reverse control circuit diagram are mapped to the simulated motor signal simulation box, that is, all the device contacts in the schematic diagram are instantiated and mapped out, which is convenient for setting and modifying the fault point, such as: the start button SB1 (normally open, state 0) is mapped to the S01 switch of the simulated motor signal simulation box. The S01 state can be modified through the software configuration file. When you want to set the SB1 fault, set the state of S01 opposite to the state of the button SB1, that is, set it to conduction (state 1). At this time, close the circuit breaker and press the start button. Students can use a multimeter to measure whether S01 is on, and judge whether the S01 device is faulty by the conduction state. Because SB1 is a normally open button, when the button is pressed, it should be in the on state, but the actual measurement result is not on, then S01 is faulty.
