1. Overview: The
ship mooring machine electrical control tr*ning device is developed according to the practical teaching and skill requirements of ship electrical, ship electrical automation, ship electromechanical and related majors in vocational colleges and various vocational appr*sal stations (institutes) and other units. The tr*ning equipment uses common electrical appliances in the industry, which can not only be used for course demonstration and electrical control operation, but also as tr*ning and assessment equipment for ship electrical m*ntenance.
2. Technical performance:
1. Input power: three-phase four-wire (or three-phase five-wire) ~ 380V ± 10%? 50Hz
2. Working environment: temperature -10℃ ~ +40℃? Relative humidity <85% (25℃)? Altitude <4000m
3. Device capacity: <1.5kVA
3. Basic configuration This device consists of power control part, instrument measurement part, ship mooring machine electrical control circuit, AC three-speed asynchronous motor , fault setting, troubleshooting box, power socket, etc.
1. Power supply control part: Provide three-phase AC power supply with leakage protection function, and equipped with a pointer-type AC voltmeter to indicate the line voltage of the three-phase power grid.
2. Instrument measurement part: Provide an AC voltmeter and an AC ammeter for control line measurement.
3. Ship mooring machine electrical control circuit: Provide buttons, AC contactors, thermal relays, transformers, AC solenoid valves, time relays and other components required for the control circuit.
4. Fault setting and troubleshooting box: It consists of "fault setting area", "fault troubleshooting area" and "fault indication area". Faults can be set arbitrarily. After the fault is eliminated, the fault indication area can automatically indicate the fault elimination situation.
5. 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 movement, and reverse movement 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 to 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 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 a PLC control function. After the connection is completed, press the PLC coding button to enter the program writing interface, and write two programs, forward and reverse. There are 12 ladder diagram symbols in total. After the writing is completed, select Submit to verify the program. After the verification is successful, turn on the power to operate. Error boxes will pop up for components, line connections, and code errors, and the scene can be reset at any time.
4) MCU control: the experiment is the same as relay control, with the addition of a single-chip microcomputer 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. Error boxes will pop up for components, line connections, and code errors, and the scene can be reset at any time.
