摘　　要：温度传感器网络广泛应用于工业农业等场合中。1-wire总线技术与传感器技术的结合简化了被测对象的监测网络设计。采用1-wire总线技术构成的传感器网络为大型的传感器网络提供了很好的前端采集网络构建方案。在分析了各种设计方案后,提出了以AT89C51单片机为主控芯片、以DS18B20为测温节点的1-wire总线温度传感器网络的设计方案,详细分析了设计流程,并给出了部分设计代码。引入用户按键和定时器,将用户的参与与无人值守的智能性进行有效的结合。为1-wire总线式传感器网络的应用设计提供了参考。Temperature sensor network is used widely in industry and agricuhure, etc. The combination of 1-wire technology and sensor simplified the design of monitoring network. A good front sampling network is suggested for large sensor network using sensor network based on 1-wire technology. After analyzing some kinds of design, a design of temperature sensor network based on 1-wire technology presented which uses AT89C51 as main controller and DS18B20 as node. The flow chart, and part of Implementation ＇code are given, too. By introducing a key for user and a timer, it combinated both advantages of user participation and unattended intelligence. It served as a good example for the design of sensor network based on 1-wire technology.
