1. Overview
In the system of medium and large ships, the navigation signal light system is an important part of the safe navigation conditions of the ship, and it is also an important lighting system to ensure the safe navigation of the ship at night. When the ship is s*ling at night, it is necessary to indicate the position and working status of the ship, so it is very important to ensure the normal operation of the ship's navigation signal light system. The "Ship Navigation Signal Light System Tr*ning Device" is developed based on the courses "Ship Electrical Equipment", "Ship Electrician Operation Skills (Intermediate)", "Ship Electrician" and "Ship Lighting" offered by vocational colleges. The device can be used as a tr*ning equipment for ship s*lors and mechanics, ship electrical, ship electromechanical and other majors in ship schools, and can also be used as a tr*ning equipment for ship engineers, ship employees, and crew tr*ning institutions .
Tr*ning device for ship navigation signal light system
2. Product features of the tr*ning device
for ship navigation signal light system 1. The system consists of a ship navigation light control console and a lamp installation platform. The navigation signal light control console is designed with reference to the structural shape of the ship's engine room control console, and is equipped with navigation signal light power supply, lamp controller, indicator light, fault alarm and other components; the lamp installation platform is specially designed with reference to the hull lamp installation regulations, and can be conveniently installed with various navigation signal lights according to the ship navigation signal light installation specifications, which is very close to the actual ship's navigation signal light system.
2. The m*n components used in the ship navigation signal light system are all real components.
3. Various navigation lights and signal lights can be installed, wired, and debugged separately, or combined into a system for installation, wiring, and debugging. Through practical tr*ning, students can master the operation methods of various navigation lights, signal lights and flashing lights (installation, wiring, dimming, test lights), debugging of navigation signal light controllers, debugging of test light boards, and wiring and debugging of control circuits and alarm circuits of various lamps, etc., which can fully meet the needs of practical tr*ning at different levels.
4. The navigation signal light system can be set up with various types of electrical faults, such as power f*lure of the navigation light system, power f*lure of the navigation light system, f*lure of the dimming circuit to dim normally, test light function f*lure, sound and light alarm function f*lure, navigation signal light control f*lure, etc. Students can find faults through debugging and then eliminate them, which is conducive to improving students' ability to rep*r common faults of ship navigation signal light systems.
5. Virtual simulation system for electrical safety and electric shock first *d: The software uses a virtual screen that combines two-dimensional and three-dimensional images to teach students electrical safety and first *d methods. 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 compression rescue method, etc. The 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 are 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 demonstration is carried out at the bidding site.
6. 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 3D machine tool model can be operated by the start/stop, forward movement, and reverse movement buttons. When the line is connected, the 3D 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 3D machine tool model. You can choose to cover the cover. Some component names can be renamed. Then click the connection line button to connect the terminals to 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, and the scene can be reset at any time.
3) plc control: the experiment is the same as relay control, with the addition of PLC control function. After the connection is completed, press the PLC coding button to enter the program writing interface, write two programs, forward and reverse, with a total of 12 ladder diagram symbols. After writing, select Submit to verify the program. After successful verification, turn on the power to operate. Errors in components, line connections, and code will pop up prompt error boxes, and the scene can be reset at any time.
4) MCU control: the experiment is the same as relay control, with the addition of MCU control function. After the connection is completed, press the C coding button to enter the programming interface, enter the correct C language code, and submit the verification successfully. Turn on the power to operate. Errors in components, line connections, and code will pop up prompt error boxes, and the scene can be reset at any time.
