IV. Device composition and configuration
1. Power control panel (aluminum panel)
(1) AC power (with leakage protection measures) is taken from the m*ns.
(2) Personal safety protection system
Voltage type leakage protector: protects ag*nst leakage in the line, causing the contactor in the control panel to trip and cut off the power supply. Current
type leakage protection device: when the leakage current in the control panel exceeds a cert*n value, the power supply is automatically cut off to protect personal safety.
2. Electrical circuit diagram of the hoist
The panel is printed with the schematic diagram of the hoist control circuit and the fault setting point, and is equipped with action indicator lights for each relay and contactor of the hoist, which can indicate the corresponding action of the relay and contactor. The working process of the control circuit of the cargo crane can be seen intuitively.
3. The electrical circuit component area of the cargo crane
The panel is equipped with circuit breakers, fuses, contactors, thermal relays and transformers, and their operation can be observed intuitively.
4. Motor and master controller
The motor of the cargo crane is simulated by a three-speed squirrel cage asynchronous motor; the fan is used for heat dissipation of the cargo crane.
The master controller is used to control the lifting operation of the cargo crane.
5. Fault switch box
There are 16 switches for fault setting and simulating the action of thermal relays and overcurrent relays.
6. Virtual simulation system for electricity safety and electric shock first *d: The software uses a virtual screen combining two-dimensional and three-dimensional to teach students the safety and first *d methods of electricity use. The software is equipped with single-phase electric shock, two-phase electric shock, step electric shock, low-voltage electric shock first *d, high-voltage electric shock first *d, artificial respiration rescue method, hand-holding breathing rescue method, chest external cardiac compression rescue method and other principle explanations and teaching, single-phase electric shock is divided into m*ntenance of live disconnection, m*ntenance of socket electric shock, outdoor electric shock and other principle demonstrations. 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 in low-voltage electric shock or high-voltage electric shock. Artificial respiration rescue method, hand-holding breathing rescue method, and chest compression rescue method are displayed using 3D virtual simulation technology. After rendering and polishing, the model looks the same as the real part, and the picture is realistic. Through practical tr*ning, students can be educated on safe use of electricity in the tr*ning room, improve their safety awareness, and learn some self-rescue methods. Students can take cert*n safety measures to protect themselves when they encounter danger, and be familiar with the causes of various electrical accidents and practical operational measures to deal with electrical accidents, so as to reduce the occurrence of electrical accidents. In order to prevent false bidding, this system is demonstrated at the bidding site. A copy of the software copyright of the virtual simulation system for electrical safety and electric shock first *d is also provided with an official seal. If a forged certificate is used, once verified, the bidder will be disqualified and the relevant responsibilities of the unit and the responsible person will be investigated.
Mechanical equipment installation tr*ning assessment software: The software is designed based on C# and JS language programming. Users can choose different sizes of interactive interfaces according to their computer configurations. Six levels of image quality can be selected, including smooth image quality, medium image quality, and perfect image quality. More than ten kinds of axis systems such as gear shaft system and worm shaft system can be selected for installation, disassembly, assembly, parts measurement, and assessment. There are intelligent reminders during the steps of parts disassembly and assembly. The models in the software are all 3D models, made by 3Dmax, and rendered and polished to make the models look the same as real parts. There are non-standard parts library, standard parts library, and measurement tool library for disassembly and assembly. The software is equipped with electronic experimental assessment questions and instructions that integrate the purpose, steps, requirements, etc. of the experiment. When using the assessment function, the software randomly asks questions for students to answer, and gives assessment scores when students finish answering the questions. This software can be rotated, enlarged, and reduced in all directions to view its det*ls. Provide on-site demonstration.
7. Tr*ning table
The tr*ning table is made of iron double-layer matte dense spray structure. The desktop is fireproof, waterproof, wear-resistant high-density board. It has a solid structure and is shaped like a cuboid. It is beautiful and elegant. There are two large drawers for placing tools and materials.

The tr*ning table is also equipped with four universal wheels and four fixed adjustment mechanisms for easy movement and fixation.
8. Single-chip microcomputer , PLC programmable design and control virtual simulation software (copyright certificate and demonstration video are required):
1) This software is developed based on unity3d, with built-in experimental steps, experimental instructions, circuit diagrams, component lists, connection lines, power on, circuit diagrams, scene reset, return and other buttons. After the connection and code are correct, the three-dimensional machine tool model can be operated through the start/stop, forward motion, and reverse motion buttons. When the line is connected, the three-dimensional machine tool model can be enlarged/reduced and translated.
2) Relay control: Read the experimental instructions and enter the experiment. By reading the circuit diagram, select relays, thermal relays, switches and other components in the component list and drag and drop them into the electrical cabinet. The limiter is placed on the three-dimensional machine tool model. You can choose to cover the cover. Some component names can be renamed. Then click the connect line button to connect the terminals. After the machine tool circuit is successfully connected, choose to turn on the power and operate. If the component or line connection is wrong, an error box will pop up. The scene can be reset at any time.
3) PLC control: The experiment is the same as relay control, and the PLC control function is added. After the connection is completed, enter the program writing interface through the PLC coding button. Write two forward and reverse programs. There are 12 ladder diagram symbols in total. After writing, select Submit for program verification. After successful verification, turn on the power to operate. If there are component, line connection, and code errors, an error box will pop up. The scene can be reset at any time.
