It applies to teaching and training of the air bag and seat belt retractor system by the air bag laboratory equipment.

Air bag and seat belt retractor system instruction board

Volkswagen Jetta (other types)  air bag and seat belt retractor system instruction board

i. About the product

 

This is an air bag laboratory equipment. The device is designed based on the Volkswagen Jetta (other types) air bag system to holistically demonstrate the structure and operation of the system. The device applies to theoretical teaching and maintenance training of the air bag and seat belt retractor system in secondary and senior vocational skill schools, normal education and training institutions.

 

 

ii. Features          

                                                                                                           

A real and operable air bag system is used to illustrate the structure of the system. Small vehicles are operated to crash with each other, simulating a traffic accident. The right and left simulated air bags quickly inflate. In this way, the device demonstrates operation of the air bag system. A color circuit diagram on the instruction board is protected by 3 mm-thick organic glass and fixed with aluminum rims. The diagram and air bag and seat belt retractor system can help trainees learn and analyze the operating principle of the system. The instruction board is installed with detection terminals to detect electric signals, for example, resistance, voltage, current, and frequency, of circuit components of the air bag system. The instruction board is installed with a diagnosis socket connecting a dedicated or universal automobile decoder. The diagnosis socket reads and clears fault codes on the air bag system.The teaching board's base frame is made of steel and the surface is paint-coated. Self-retention wheels are installed to ensure that the board is flexible, reliable and endurable. Instead of using accumulators and requiring charging, the instruction board connects to a 220V AC voltage which changes to a 12V DC voltage through the internal circuit. The 12V DC voltage protects the instruction board against short circuit. Intelligent fault-setting and appraisal system:

1)     The system employs patented, stable and anti-virus digital integrated circuit board and the latest MCU technology and associated fault setting control technology.

2)     Independent test and appraisal can be performed without a computer. The teacher and student interfaces are separated. Teachers enter the teacher interface to provide test paper and the students answer questions on the ordinary interface. Teachers prepare the test: teachers prepare the test: Select "Setting fault point and fault type" through the main functional menu in the MML interactive interface. Enter the password to page for setting faults. Select the set faults from the fault name list. You can select three fault types including "Open circuit fault", "Short circuit fault", and "Improper contact". Students answer questions: Enter the main menu and select "Test for skills of finding faults". After finding the fault through a test operation, students select the fault name or type. If the answer is correct, the system displays that "Correct, the fault is removed"; If the answer is incorrect, the system indicates that "incorrect, please check again". The number of attempts for each question can be set to 1-10 by the teacher. Test bank applicable to the device is integrated. The test bank can be edited according to the requirements of users.

3)     High resolution 3.8-inch 0.225 x 0.225 LED monitor, Chinese menu interface, friendly MML. 4 operation keys make the operation simple and quick.

4)     Set the line breaking, grounding short circuit and improper contact faults at any circuit. Set and control common faults relevant to module pins. Users can adjust the number and type of fault setting points.

5)     The RJ45 network interface is installed and the RS-232 port is provided. Use the fault setting devices of network cable or other devices to form a network to control functions including fault setting, fault removal, parameter setting, remote startup, information feedback, and appraisal through the main control computer.
