The Design of Data Acquirement System Based On Can Bus Technology Ji Dou, Wang Xiangjun (Inst.of Elec.and Info.of Eng.，Naval Univ. of Engineering，Wuhan 430033,China) Abstract：In ocean environment, it is demanded to collect and transmit various parameters at real time and long distance. A novel hardware and software design projection of long distance data acquirement based on CAN bus is proposed after analyzing several other long range data collection styles in this paper. The experimental result of ship electromagnetic
field collection proved the high performance of this system in aspects of rapid delivering,
far distance, high reliability and fine performance price ratio.
