摘要
目前,测控技术广泛应用于炼油、化工、冶金、电力、轻工和纺织等行业。本文设计了基于CAN现场总线的测控网络中下位机节点的设计,开发了基于DSP的下位机节点CAN现场硬件智能测控装置及通讯软件。通讯软件主要包括三大模块:CAN现场智能测控装置初始化,报文发送及中断接收,基于自定义协议Proto-Can节点的协议实现即D/A,A/D等子程序。
Recently, the measurement and control technology is commonly used in many areas. The slave nodes design of the measurement and control network based on CAN field bus technology is introduced in this paper. The communication software and CAN intelligence control device of slave nodes based on DSP （TMS320LF2407） is designed. It mainly includes modules： the initialize of CAN intelligence control device, the transmission and the interrupt reception of the message, the realization of nodes protocol based on user-defined protocol and subprograms of D/A, A/D.
