The above abnormal voltage will lead to the inability to accurately control the correct acquisition of the VIN code of the vehicle
The VIN code is broadcast unstable on the CAN data platform, and the data is prone to loss or inaccuracy
At the same time, the control of the vehicle door valve requires high accuracy, which is affected by the fluctuation of the power supply on the existing vehicle, which has a great impact on the control accuracy of the door valve, thus affecting the overall stability and safety of vehicle control

Embodiment 1
[0043] In the technical solutions disclosed in one or more embodiments, such as figure 1 As shown, a VIN code and emergency valve multifunctional integrated control system, including a central processing unit 1, a CAN bus interface circuit 2, a signal input circuit 4, a power module 3 and a CAN input and judgment circuit 5;
[0044] The central processing unit 1 includes a VIN code control module: used to input and store the VIN code, and control the output of the VIN information of the VIN code;
[0045] Signal input circuit 4: used to transmit the vehicle status signal to the central processing unit;
[0046] CAN bus interface circuit 2: used to connect the central processing unit 1 and the data transmission bus of the vehicle, used to send the VIN code information processed by the central processing unit to the host computer;
[0047] CAN input and judgment circuit 5: connected to the output end of the CAN interface circuit 2, used to realize the conversion of the informat...
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...

Abstract
The invention provides a VIN code and emergency valve multifunctional integrated control system and method. The VIN code and emergency valve multifunctional integrated control system comprises a central processing unit, a CAN bus interface circuit, a signal input circuit, a power module and a CAN input and judgment circuit. The central processing unit comprises a VIN code management and control module which is used for inputting and storing VIN codes and controlling output of VIN information of the VIN codes; the signal input circuit is used for transmitting the vehicle state signal to the central processing unit; the CAN bus interface circuit is used for connecting the central processing unit with a data transmission bus of a vehicle and sending the VIN code information processed by the central processing unit to an upper computer; and the CAN input and judgment circuit is connected with the output end of the CAN interface circuit, and is used for realizing conversion of the information data format of the VIN code and feeding back the converted information data format to the central processing unit. Thus, the safety and stability of vehicle control can be improved, the VIN code isset to be electronic information for storage and whole vehicle display, the requirement for VIN code setting is met, meanwhile, the requirement for further improvement of vehicle intelligence can bemet, and the efficiency and cost of vehicle management are improved.
Description
technical field [0001] The present disclosure relates to the technical field related to vehicle control, and specifically relates to a VIN code and emergency valve multifunctional integrated control system and method. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and may not necessarily constitute prior art. [0003] Vehicle Identification Number (Vehicle Identification Number, or VIN), referred to as VIN, is a set of seventeen English letters and numbers, a unique set of numbers used on a car, which can identify the car's manufacturer, engine, Chassis serial number and other performance information. The vehicle VIN code is the unique code of the car in the world. Most of the existing vehicle VIN codes are set on various positions of the vehicle by pasting, engraving, etc. The setting position of the VIN code can be on the dashboard or through the front panel of the windshield On the sti...
