摘要
针对温度检测的特殊要求,结合CAN总线的优点,提出了一种基于CAN总线的温度检测节点的设计方案;以89C51为核心,采用高精度数字温度传感器DS1820进行现场采集,通过CAN总线与上位机(操作站)进行远程通讯,从而实现现场智能节点间的温度传递及将温场信号的快速、准确上传。
Aiming at the special request of the temperature detection and combining the CAN BUS advantage, this paper gives a design method of temperature monitoring node based on the CAN BUS. The system adopts MCU 89C51 as the controller, and high precision numeric temperature sensor DS1820 to gather data in field. CAN Bus is adopted to communicate with the computer. The system implements the temperature transference among the intelligent field nodes and uploads the temperature field signal to computer well and truly.
