3. Equipment structure and function

This tr*ning platform consists of three parts: a tr*ning screen (built-in power supply), a tr*ning table, and a tr*ning locker. 30mm×30mm formed square steel is used as the m*n frame material of the equipment; the tr*ning screen and floor are welded and connected, and key parts are reinforced with triangular ribs and hexagonal socket screws. The surface is treated with high-temperature spray plastic, which is beautiful and elegant and effectively acts as an anti-rust insulation. The function of the mesh plate fixing mechanism is composed of two 35mm×35mm aluminum alloy profiles and chutes. Below the fixing mechanism is an iron double-station power box. The layout of each station power box is a power protection device and a power indicator. device, power output; the top of the tr*ning table is made of 25mm heather gray high-density laminate edge sealing, which effectively improves the insulation level; the bottom of the experimental table is equipped with at least 4 guide wheels to facilitate the movement of the tr*ning bench;

The tr*ning locker adopts a standard structure and drawer type. There are three drawers on the left side for storing tools and tr*ning materials. The double sliding door design on the right side can store two universal hanging boards at the same time. The position of the tr*ning locker can be flexibly adjusted according to needs, and the overall dimensions are: 1300mm×600mm×510mm.

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 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.

3. Microcontroller and plc programmable design and control virtual simulation software:

This software is developed based on unity3d and has built-in experimental steps, experimental instructions, circuit diagrams, component lists, connection lines, power on, circuit diagrams, scene reset, return and other buttons. After the connections and codes are correct, you can start/stop, The forward movement and reverse movement buttons operate the 3D machine tool model to move. In the connected line state, the 3D machine tool model can be enlarged/reduced and translated.

1. Relay control: Read the experiment instructions and enter the experiment. By reading the circuit diagram, select the relays, thermal relays, switches and other components in the component list and drag and drop them into the electrical cabinet. The limiters are placed in the three-dimensional On the machine tool model, you can choose to cover it, and some component names can be renamed. Then click the Connect Line button to connect terminals to terminals. After successfully connecting the machine tool circuit, choose to turn on the power and proceed. If the component or line An error box will pop up if there is a connection error, and the scene can be reset at any time.
