7: 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.

2. PLC control: The experiment is the same as relay control, with the addition of PLC control function. After the connection is completed, enter the program writing interface through the PLC coding button, and write two programs, forward and reverse, with a total of 12 ladder diagram symbols. The writing is completed. Finally, select Submit for program verification. After the verification is successful, turn on the power for operation. Error boxes will pop up for component, line connection, and code errors, and the scene can be reset at any time.

3. Single-chip microcomputer control: The experiment is the same as relay control, with the addition of single-chip microcomputer control function. After the connection is completed, enter the programming interface through the C coding button, enter the correct C language code, and after successful submission and verification, turn on the power for operation, components, lines If there are connection or code errors, an error box will pop up, and the scene can be reset at any time.

2. Product structure:

Table body part: Made of 40*40 industrial aluminum alloy as the frame, hexagonal prism cube structure.

Desktop part: It is made of black 12.7mm thick physical and chemical board with embedded 304 st*nless steel universal mesh plate (600*300㎜). The experimental module and the universal mesh plate are interchangeable and can be used alternately for easy operation.

Practical tr*ning screen part: The entire screen adopts steel-wood structure. The frame is made of high-quality steel, and the outer surface is sprayed with colored epoxy polyplastic. The tr*ning screen panel adopts a 4mm thick aluminum plate structure, which is dust-proof, beautiful, wear-resistant, and does not fade. Above the tr*ning screen is a rotatable aluminum disc that can carry typical work task carriers at multiple angles.
