摘　　要：基于MSP430单片机的低功耗和CAN总线抗干扰能力扰强的特点，该文设计了一种以MSP430超低功耗单片机为现场节点控制中心的输入输出系统。利用CAN总线接口实现同上位机的数据远程传输。该系统能够很好的完成模拟量和数字量的采集和输出、实时的显示、数据的远程通讯要求。该系统对于应用在现场设备中的有一定的参考价值。This paper designes a input and output system of field node controlling center with MSP430 ultra-low-power microcontroller based on the low power operation of MSP430 and powerful anti-interference performance of CAN bus.Using CAN bus interface achieves the long-distance data transitance with upper machince. The system performances well in acquiring and outputing of analog and digital sig- nals, displaying real-time and long distance communication of data. Therefore, the system provides a reference to the application of field devices.
