Product Requirement
The Educational Equipment CAN data transmission network system teaching board uses the physical object of the Volkswagen Passat CAN data transmission network system as the basis, fully demonstrating the composition structure and working process of the CAN data transmission network system.

Functional Requirements
1. The real and operational CAN data transmission network system fully demonstrates the composition structure of the vehicle network system.

2. The circuit elements that manipulate various data transmission signals, such as gear switch, throttle signal, speed signal, water temperature signal, anti-theft signal, power window switch signal, door lock signal, etc., to truly demonstrate the working process of the CAN data transmission network system .

3. The measurement panel of the training platform is painted with a color inkjet circuit diagram, which is made of a 5mm thick high-strength transparent acrylic sheet mirrored on the back. It is resistant to large temperature differences, wear resistance, moisture resistance, corrosion resistance, not easy to deform, and has a long service life. Bright colors, not easy to fade, etc.; students can intuitively compare circuit diagrams and real objects to understand and analyze the working principle of the vehicle network system.

4. There are detection terminals installed on the panel of the teaching board, which can directly detect the electrical signals of various circuit elements of the CAN data transmission network system, such as resistance, voltage, current, frequency signals, etc., on the panel.

5. A diagnostic socket is installed on the panel of the teaching board, which can be connected to a dedicated or general-purpose car decoder to perform ECU coding query on the control unit of the engine system, automatic transmission system, instrument system, ABS system, and comfort system connected to the vehicle network , Reading fault code, clearing fault code, reading data stream, executing component test, parameter setting, waveform analysis, key matching and other self-diagnostic functions.

6. The training platform is built with international standard aluminum alloy profiles. It has the characteristics of light weight, high strength, corrosion resistance, and long life. It does not need to go through the spraying process, and is more environmentally friendly. The appearance is more beautiful and high-end. The bench has self-locking casters. The device is flexible to move, safe, reliable, sturdy and durable.

7. The teaching board uses an ordinary 220V AC power supply, which is transformed into a 12V DC power supply by internal circuit transformation and rectification, without the need for batteries, reducing the trouble of charging, and the 12V DC power supply has the function of preventing short circuits.
