6. Simulation experiment software:

1. Electricity safety and electric shock first *d virtual simulation system (demo and copyright certificate provided): 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, and two-phase electric shock first *d. Principles of electric shock, step-over electric shock, low voltage electric shock first *d, high voltage electric shock first *d, artificial respiration rescue method, holding hands breathing rescue method, chest heart compression rescue method, etc., single-phase electric shock rep*r live disconnection, rep*r socket electric shock, outdoor Demonstration of principles such as 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.

2. M*ntenance of electricians, electronic motors and vocational qualification tr*ning assessment simulation software (providing demonstration and copyright certificate): The software content includes common sense of safe electricity use, electrician tools, electrician diagrams, electrician instruments, electrician lighting circuits, motors, transformers, low-voltage electrical appliances, Electric mops, oscilloscopes, low-frequency signal sources, welding processes, SMT technology, electronic product manufacturing processes, troubleshooting, wiring, three-dimensional disassembly and assembly of reducers, disassembly and assembly of shafting mechanisms (including cylindrical gear shafting, bevel gear shafting, worm shaft Department and more than ten experiments) and other modules, schools can select corresponding tr*ning modules for tr*ning according to students' learning progress.

3. Three-meter simulation software (demo and copyright certificate provided): This software is in apk format and can be used on PC or mobile terminals. The functions of this software are: measurement of resistance and measurement of AC voltage ( Measuring the transformer, if the multimeter burns out when measuring the transformer, black smoke will appear and the multimeter can be reset), transistor polarity judgment, DC voltage measurement (the light will turn on when the ammeter is turned on), DC current measurement, and capacitance is good. Bad judgment. This software can drag the red and black pen tips at will. When the two pen tips are dragged and positioned on the object to be measured, a red circle will be displayed. If the positioning is not accurate, no red circle will be displayed, and when incorrect operations are performed (such as the wrong range selected, If the measured data is wrong, etc.), the meter pointer will be unresponsive, prompting errors and re-measurement, etc. This multimeter can select AC voltage range, DC voltage range, resistance range, current range, resistance adjustment to 0, and can enlarge the display data. Clearly view the measured data size. Students can learn the correct use of multimeters through this software.

4. Teacher teaching design system (provides demonstration and copyright certificate): This system is in apk format and can be used on PC or mobile. This system can set faults manually or automatically. This system has passed The green box in the circuit diagram selects manual setting of fault points (up to 39 fault points can be set), or the system can automatically set one random fault point, two random fault points, three random fault points, and four random fault points automatically. Fault point setting, five random fault point settings. This system has toolbox, component library, magnifying glass, circuit diagram and other functions. You can choose a multimeter for detection through the toolbox, select appropriate components through the component library, and you can clearly see the results through the magnifying glass. Understand the various components and circuits. This system allows students to understand the working principle and circuit structure of the motor star-delta start control circuit through the setting of faults in the motor star-delta start control circuit and various investigations.
