Abstract

One kind of current data acquisition system based on CAN(Controller Area Network) bus is designed its core design is CAN bus controller SJA1000.The principle of the data acquisition system and the software and hardware design of a single node are given. The main concerns are design,the realization and the rules of the intelligent node of CAN bus. The result of test shows three aspects of advantages. The multi-master capabilities of CAN bus make the system reset more smartly.The speed rate of data transmission reaches 1 Mbit/s. The stability and good reliability of data transmission can meet the real-time need of the field. Dependability is good, and the field real time demand is satisfied. Meanwhile the expenses of connecting wires, maintenance and installation are decreased because of the use of CAN bus. It improves the price ration of the system. Thus it will be widely applied.
