Vehicle Information Collection and Communication System Based on CAN Bus and GPS

Abstract

With the proportion of automobile industry in people's work and life increasing year by year, the automotive intelligent terminal market has ushered in a huge development prospect. On-board information system is a set of control system used to collect, store and display all kinds of information status in the process of automobile running. Controller Area Network (CAN) is a serial communication field bus network that effectively supports distributed monitoring or real-time control. Through the CAN bus technology, the vehicle-mounted intelligent terminal can easily interact with other devices in the automobile, so as to master the running status of the vehicle. The vehicle-mounted 3D acquisition system continuously acquires the traveling position of the measuring vehicle through GPS, and provides geographic coordinates for the 3D spatial images acquired by the measuring vehicle, thus realizing the 3D scene with spatial geographic coordinates. Relying on CAN bus and GPS technology, the vehicle-mounted intelligent terminal can conveniently obtain the surrounding road condition information and send its own vehicle data to the remote control center.
