4. System composition:

This device consists of a physical pulsator washing machine, an electrical control panel, a tr*ning and assessment system and an experimental bench.

1. Physical pulsator washing machine: It adopts the popular physical design of pulsator, including inlet and dr*nage system, motor and mechanism transmission system, and supporting machine washing and dehydration mechanism;

2. Electrical control panel: The electrical control system of the pulsator washing machine, including water level detection, solenoid valve control circuit, motor control, electric range controller, automatic control processor and other units;

3. Practical tr*ning assessment system: The fault setting mechanism adopts a concealed design. Students can eliminate faults through the troubleshooting unit according to the fault phenomenon. The assessment time and process can be fully recorded and monitored.

4. Tr*ning control cabinet: The overall adopts a three-dimensional cabinet structure and is equipped with four universal wheels with brakes, which is easy to move and fix, and is conducive to the layout of the tr*ning room. The cabinet is made of waterproof, waterproof and wear-resistant aluminum alloy material, with solid structure and beautiful appearance. At the same time, the physical object and the control panel can be closely integrated to facilitate students' operation.

5. Electricity safety and electric shock first *d virtual simulation system: The software uses a virtual screen that combines two-dimensional and three-dimensional to teach students the safety of electricity and first *d methods. The software has single-phase electric shock, two-phase electric shock, step electric shock, low voltage Principles of first *d for electric shock, first *d for high-voltage electric shock, artificial respiration, hand-holding breathing rescue, and external chest cardiac compression are expl*ned and taught. Principles of single-phase electric shock are divided into rep*ring live disconnection, rep*ring socket electric shock, and outdoor electric shock. The teaching of low-voltage electric shock and high-voltage electric shock m*nly expl*ns and demonstrates to students how to rescue people who are suffering from low-voltage electric shock or high-voltage electric shock. Artificial respiration rescue method, hand-holding breathing rescue method, and chest cardiac compression rescue method are demonstrated using 3D virtual simulation technology. After rendering and Polish it to make the model look like the real part and look realistic. Through practical tr*ning, students can be educated on the safe use of electricity in the tr*ning room, improve students' safety awareness, and enable students to learn some self-rescue methods, so that students can take cert*n safety measures to protect themselves when encountering danger, and become familiar with various Causes of electrical accidents and practical measures to deal with them to reduce the occurrence of electrical accidents.
