摘　　要：本文设计的是一种基于CAN总线的核数据采集卡。该采集卡在ARM7处理器的控制下进行数据采集和缓存,并定时通过CAN总线传输数据给上位机。它大大提高了数据采集精确度、抗干扰能力和远距离传输可靠性,并且组网方便。This paper designed a kind of data acquisition card based on the CAN bus. The acquisition card collect and cache data under the control of ARM7 processor, and regularly transmit data through the CAiN bus to the PC. It has significantly improved the accuracy of data collection,Anti-jamming capability and reliability of long-distance transmission, and convenient network.
