在海洋環(huán)境中，可能需要對(duì)多種物理參數(shù)進(jìn)行采集與傳輸。本文在分析比較多種遠(yuǎn)程數(shù)據(jù)傳輸方式的基礎(chǔ)上，提出一種基于CAN 總線技術(shù)的遠(yuǎn)程數(shù)據(jù)采集系統(tǒng)的硬件和軟件設(shè)計(jì)方案。使用該系統(tǒng)對(duì)水下物理場(chǎng)進(jìn)行了數(shù)據(jù)采集實(shí)驗(yàn)，結(jié)果表明該系統(tǒng)通信速率高、傳輸距離遠(yuǎn)、可靠性好且性價(jià)比高。

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.
