基于CAN总线的温度监控系统

A System of Tempreture Control Iing Based on the CAN bus

综述了CAN总线产生和发展过程,概括了CAN总线优于其它现场总线的特点,结合生产中温度监控的实际需求,提出了将CAN总线应用于生产实践的设想。给出了基于CAN总线的温度监控系统的设计方案,依据系统的结构,从两个方面详细地阐述了系统的设计方法,即节点控制器的实现和智能节点的实现。

This paper elaborates comprehensively the process of production and development of the CAN bus, summarizes the features of the CAN bus superior to any other field bus, and brings up the idea of applying the CAN bus to practical production. A program of tempreture controlling based on the CAN bus is advanced in this paper as well. According to the structure of the system, the design approach is described in length from two aspects-realization of node-controller and of intelligent node.
