Abstract

A multi-channel CAN vehicle information acquisition system based on a 4G communication mode comprises a plurality of CAN bus modules which are connected with a vehicle bus system and used for acquiring information data of a whole vehicle state; a microprocessor module connected with the CAN bus modules and used for receiving the information parameters, obtained by the CAN bus modules, of the whole vehicle state; a signal transmitting module connected with the microprocessor module and used for transmitting the information parameters of the whole vehicle state received by the microprocessormodule; and a data storage server connected with the signal sending module and used for receiving the signal sending module sent by the signal sending module. The system has a basic function of communicating with a vehicle, can complete the complete collection of CAN bus data of the whole vehicle, uploads the collected data to a data storage server through a 4G network, and has the advantages ofdata synchronism and strong processing capability.

Description

technical field [0001] The invention relates to the technical field of information collection systems, in particular to a multi-channel CAN vehicle information collection system based on 4G communication. Background technique [0002] A driverless car is a smart car that senses the road environment through an on-board sensor system, automatically plans a driving route, and controls the vehicle to reach a predetermined target. It uses on-board sensors to perceive the surrounding environment of the vehicle, and controls the steering and speed of the vehicle based on the road, vehicle position and obstacle information obtained from the perception, so that the vehicle can drive safely and reliably on the road. Integrating many technologies such as automatic control, architecture, artificial intelligence, and visual computing, it is a product of the highly developed computer science, pattern recognition, and intelligent control technologies. It is also an important symbol to meas...
