1. Product introduction
The equipment is based on the Volkswagen Jetta 1.6L automobile manual air-conditioning system, which fully demonstrates the composition structure and working process of the automobile manual air-conditioning system. It is suitable for the teaching needs of middle and higher vocational technical colleges, general education colleges and training institutions on the theory and maintenance of automobile manual air-conditioning system.
2. Features
1. A real and operational automobile manual air-conditioning system, which fully demonstrates the composition structure and working process of the automobile manual air-conditioning system.
2. The three-phase motor is used as the power source to drive the air-conditioning compressor to work. Operating the air conditioning control panel can truly demonstrate the working process and working principle of the car's manual air conditioning system.
3. The training platform adopts 4mm-thick high-grade aluminum-plastic panels with corrosion resistance, impact resistance, pollution resistance, fire resistance and moisture resistance. The surface is treated with a special process spray primer; the panel is printed with color circuit diagrams and working principle diagrams that will never fade , The surface is sprayed with varnish; the trainees can visually compare the circuit diagram and the real object to understand and analyze the working principle of the automobile manual air-conditioning system.
4. There are detection terminals installed on the panel of the training platform, which can directly detect the electrical signals of various circuit elements of the air conditioning system, such as resistance, voltage, current, frequency signals, etc., on the panel.
5. High and low pressure gauges and temperature gauges for air inlet and outlet are installed on the panel of the training platform, which can display real-time parameter changes of air-conditioning pipeline pressure and air inlet and outlet temperature.
6. The training platform provides a practical work platform for trainees to practice refrigerant filling and leak detection.
7. The base of the training platform is welded with a steel structure, and the surface is treated with a spraying process, with self-locking casters, which is flexible in movement, safe, reliable, and durable.
8. Equipped with an intelligent fault setting and assessment system:
★Fault setting and assessment system composition:
1. Informatization teaching two-dimensional code panel: there are detection terminal jacks for sensors and actuators on the panel, and at the same time match the two-dimensional code information curriculum learning information identification corresponding to the individual module. Scanning the code can display the current component principle and technical data.
2. In the actual teaching environment, the teacher guides the students to install and log in to the integrated micro-course teaching APP on the mobile device, and scan the device's QR code to enter the system course for autonomous learning. The learning content must be fully matched with the integrated QR code work page course.
3. The training platform is equipped with simulated fault settings and teaching assessment devices. The 7-inch touch screen can set one or more common faults to meet the requirements of vocational skills teaching. The fault content includes: open circuit, virtual connection, and accidental. Number of failures: 8 or 16 single points. Teachers can set faults in a variety of ways, such as single-point fault setting, combined fault setting, and fault setting assessment, which is also convenient for students to practice in class and exercise their practical ability.
4. The teacher can remotely send fault setting instructions to the training equipment through the wifi connection of the teaching software. Assessment: The teacher uses the assessment method to set the fault in the comprehensive fault setting. The students conduct remote fault diagnosis and troubleshooting in the virtual diagnosis by observing the current fault phenomenon of the training platform, and fill in the diagnosis result into the training assessment, and the system determines Diagnose the results and automatically score the assessment.
