A multi-channel temperature acquisition system based on ARM and Can bus

The paper presents a new type of multi-channel temperature acquisition system equipped with Samsung S3C2410 and combined the Can bus communications technology. The system real-timely tests and controls information which is passed by the Can bus. According to the control information, it collects multi-channel temperature, then passes the temperature signal to total controller by the Can bus. The hardware and program flow is also presented. Experiments shows, this system has the advantage of collection temperature precise, high reliability, and communication distance. So it can be widely used in various industrial controls.
