摘要
介绍了基于CAN总线的分布式测控系统智能节点的开发与设计 ,对硬件组成、通信接口和软件流程作了较详细的说明 ,侧重介绍了热电偶信号的数据采集、处理和SJA10 0 0CAN控制器的应用。该智能节点可与上位机联接 ,构成分布式测控系统 。
The development and design of intelligent mode of CAN bus based distributed measuring and control system are presented. The hardware composition, communication interface and software flowchart are described in detail. The data acquistion and data processing of thermocouple signals, and the application of SJA 1000 CAN controller ane emphasized. The intelligent nodes can be connected with host computer to build a distributed measuring and control system. The systems have been used in several industrial plants.
