摘　　要：介绍了一种基于控制器局域网(CAN)总线的工程机械分布式工况检测系统,重点讨论了基于 AT89C52单片机的智能化检测系统智能节点的具体设计.该智能检测节点通过 CAN 总线与主控计算机相连,构成一种基于 CAN 总线的分散式高精度工况参数检测系统.完成了工况参数信号测量电路的硬软件设计与通讯模块电路的设计,以及系统的软件开发.该系统的实现方法对其他 CAN 总线控制模块系统设计,以及其他工程装备分布式检测与控制应用系统的开发都具有一定的参考价值.This paper introduces a type of running status parameter testing system based on controller area network(CAN)bus with construction machinery,and places emphasis on the design of intelligent field con- troller.The distributed testing node connects to the host computer via CAN bus to form a distributed high- precision status parameters testing system.The hardware and software structure of the distributed testing sys- tem as well as communication module are implemented.In addition the software architecture is designed.The solution may have some reference value to the design of other distributed measurement and control system with CAN bus and the development of general single chip microcomputer and industrial field monitoring and con- trolling system.
