摘要
为推广新型温度传感器的应用,介绍了数字式集成温度传感器DS18B20的结构、原理和接口技术.阐述了将其应用于多点温度检测系统中的若干关键技术问题.通过对主要运行参数的计算和使用常规单片机开发工具,已将该传感器成功地应用于冰箱生产的多点温度在线检测系统中,投资节省,运行可靠.
In order to diffuse the applications of a new type of temperature transducer, its structure, principle and interface technology were introduced. Some key technology issues of measuring temperature system with DS18B20 devices were put forward. By calculating the operation parameters and using usual developing tool of single-chip computer, this device has been applied successfully to a multi-point measuring temperature line of a refrigerator enterprise. The effect of this project shows high operational reliability and low costs.
