Embodiment 2
[0073] This embodiment provides a working method of a VIN code and emergency valve multifunctional integrated control system, including the input and output of VIN code information, and the switch control of the emergency valve. The input of VIN code information is as follows:
[0074] Step A1, the host computer calibrates the VIN code information of the device;
[0075] Step A2, connect the OBD interface of the vehicle through the calibration device, and transmit the VIN information to the CAN bus interface circuit through the vehicle CAN bus;
[0076] Step A3, the CAN bus interface circuit judges the format of the VIN code information, and converts the VIN code into a TTL data stream;
[0077] Step A4, transmitting the converted data to the central processing unit.
[0078] The above steps can be the settings of the vehicle before leaving the factory. The vehicle goes off-line to read and write the central processing unit through the calibration device, and store the VIN co...
