单总线多点温度数据采集系统的设计和实现

摘要

基于单总线技术,设计了多点温度数据采集系统,给出了设计方案和软件流程图以及部分源程序.此温度数据采集系统应用于三坐标测量机温度补偿,取得了良好的效果.%The basic principles and. advantages of 1 -wire bus technology were introduced. Based on the technology, a multiple temperature data acquisition system was designed. The schematic diagram of hardware and software flow chart were shown and some source codes were listed. The system is applied in a CMM's temperature data collection, and good results have been achieved.
