In addition, it can also automatically record the number of leakage alarms caused by operating errors, providing a unified standard for the assessment of students' practical tr*ning skills.
2. The m*n body of the control cabinet.
   The control cabinet is divided into four parts.
   The first part is the electrical circuit part of the M7120 grinder. All the components of the M7120 grinder are installed on this panel.
   The second part is the fault setting box. There are two kinds of machine tools printed on the fault box cover. The electrical schematic diagram shows that there are 32 fault switches in the fault box, including 16 fault points for the M7120 grinder and 16 fault points for the C6140. The fault box door is equipped with a key for easy management and assessment;
   the third part is for the C6140 ordinary The electrical circuit part of the lathe. All the components of the C6140 lathe are installed on this panel.
   The fourth part is the motor panel. There are three motors. They are used to simulate the actions of various moving parts of the actual machine tool, and the wires of the motor and speed relay. All are led to the panel with pillars for easy testing.
3. Virtual simulation system

1. M*ntenance of electricians, electronic motors and vocational qualification tr*ning assessment simulation software

This software is in apk format and can be used on PC or mobile. This software can set faults manually or automatically. This software can manually set fault points through the green box in the circuit diagram (you can set up to 39 fault points), you can also automatically set one random fault point, two random fault points, three random fault points, four random fault points, and five random fault points through the system. It has functions such as toolbox, component library, magnifying glass, circuit diagram, etc. You can choose a multimeter for testing through the toolbox, select appropriate components through the component library, and clearly understand each component and circuit through the magnifying glass. This software 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.

2. Virtual spectrum analyzer, logic analyzer, oscilloscope, and three-meter simulation software:

This software is in apk format and can be used on PC or mobile terminals. The functions of this software are: resistance measurement, AC voltage measurement (measuring transformer, if the multimeter burns out when measuring the transformer, black smoke will emit prompts and can reset the multimeter), determine the polarity of the transistor, measure the DC voltage (the light turns on when the ammeter is turned on), measure the DC current, and determine the quality of the capacitor. This software can drag the red and black pen tips at will. When the two pen tips are dragged and positioned on the measured object, 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 not respond, 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.
