摘　　要：研制了一种基于CANOPEN的分布式智能多路变压器温度变送器。该模块以AT90CAN128为核心,可同时实现8路热电阻或热电偶测温功能,并将测量结果发送到CANOPEN主站节点。实验结果表明,主从站之间的数据通信可靠、准确,实时性满足测控系统要求。An intelligent distributed multi-channel temperature transmitter for transformer based on CANOPEN was designed.Taking AT90CAN128 as core,the temperature measure of 8-channel thermal resistance or thermocouple was realized simultaneously,and the measure results were send to CANOPEN master node by the module.Test result shows that data communication between master and slave is reliable and accurate,and real time meets demand of control system.
