提出了一种基于ARM7微控制器LPC2292的CAN总线分布式控制系统智能数据采集节点的设计,给出了系统硬件框图,数据采集、CAN通信初始化、数据发送和数据接收等部分的程序设计流程图,所设计节点实现方法简单,外扩器件少,蛄构合理,可靠性高,且节点扩展方便,已用于某工业现场,波特率为10Kbps.图7,参8.
Controller Area Network (CAN) is a kind of serial communication network that supports the distributed control and the real time control,and has characteristics of high capability and high reliability. Put forward design of CAN bus intelligent data collect node which based on ARM7 single-chip LPC2292. Given the system hardware frame diagram, program design of the data collect,CAN communication initializing,sending and receiving. The design was suitable for some industry scene, Band Rate equation 10kbps. 7figs., 8refs.
