1. Overview
This tr*ning device is developed for teaching and tr*ning assessment of marine electrical and marine engineering majors in maritime vocational colleges, social shipbuilding and rep*r units, and crew tr*ning institutions . It is suitable for classroom demonstrations, operation of marine electrical control, and tr*ning practice. At present, most marine electrical towing equipment is still m*nly controlled by relay contactor circuits. Most marine equipment is frequently used, continuously operated, or frequently operated, and a high f*lure rate is inevitable. This requires marine personnel to thoroughly understand the electrical circuits in order to achieve the purpose of rapid troubleshooting.

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, trips the contactor in the control panel, and cuts 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.
Virtual simulation system for electricity safety and electric shock first *d: the software uses a combination of two-dimensional and three-dimensional virtual images to teach students electricity safety and first *d methods. The software has 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 compression rescue method and other principle explanations and teaching. Single-phase electric shock is divided into live line disconnection m*ntenance, socket rep*r 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.
2. Anchor winch electrical circuit diagram
The panel is printed with the schematic diagram and fault setting points of the anchor winch control circuit, and is equipped with relay and contactor action indicator lights, which can indicate the corresponding actions of the relay and contactor. The working process of the anchor winch control circuit can be seen intuitively.
3. Anchor winch electrical circuit component area
The panel is equipped with components such as circuit breakers, fuses, contactors, thermal relays and transformers, and their actions can be observed intuitively.
4. Motor and master controller
The anchor winch motor is simulated by a three-speed squirrel cage asynchronous motor.
The master controller is used to control the anchor lifting and anchoring operations of the anchor winch.
5. Fault switch box
There are 16 switches for fault setting and simulation of thermal relay action and overcurrent relay action.
6. Tr*ning table
The tr*ning table is an iron double-layer matte dense spray structure. The desktop is a fireproof, waterproof, wear-resistant high-density board with a solid structure and a rectangular shape. It is beautiful and generous; there are two large drawers for placing tools and materials. The desktop is used to install the power control panel and provide a spacious and comfortable work surface. The tr*ning table is also equipped with four universal wheels and four fixed adjustment mechanisms for easy movement and fixation.
7. 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.
4) Single-chip microcomputer control: The experiment is the same as the relay control, with the single-chip microcomputer control function added. After the connection is completed, enter the programming interface through the C coding button, enter the correct C language code, submit the verification successfully, turn on the power to operate, and the component, line connection, and code errors will pop up an error box. The scene can be reset at any time.
