摘　　要：设计了基于DS18B20传感器的分布式温度监测系统,给出具体应用电路,并重点介绍了DS18B20的读写方法.软件设计基于嵌入式实时操作系统uCOSII,保证了系统实时性和可扩展性,在中央空调实验系统中应用该系统,达到预期的技术指标.In this paper, the distributed temperature detection system based on sensor DS18B20 is designed,the application of specific circuit is given,and the method to read and write DS18B20 is emphasized. The software design is based on embedded real time operation system uCOS Ⅱ, which guaranteeing real time performance and scalability of the system. The anticipated design goal is reached when the detection system was applied in central air condition system.
