摘　　要：通过对一线总线数字式温度传感器DS18B20与传统温度传感器的性能对比,确定采用DS18B20作为温度传感器构建由一台上位机(PC)和多台下位机(单片机系统)组成的两级分布式多路温度检测系统作为基本温度检测系统,并在此基础上进一步阐述了综合舒适性测试室温度检测系统的总体设计方案及数据采集软件的功能。检测系统实现了多路温度检测信号的采集、处理、分析,结构简单,测量精度高,抗干扰能力强,工作稳定可靠,满足了客户的需求,取得了较好的经济效益和社会效益。By comparison of the performance of 1 wire-bus digital temperature sensor DS18B20 with traditional temperature sensor,it is determined that by using temperature sensor DS18B20 to construct as the two-stage distributed multi-channel temperature detection system which consists a stage crew（PC） and multi-audience-bit machine（MCU system） and takes it as the basic temperature detection system. Further more, on this basis, it elaboractees the overall design plan for comprehensive comfort test chamber temperature detection system and the function of data acquisition software. Detection system achieves a multi-channel temperature detection signal acquisition, processing, analysis, simple structure,high accuracy, strong anti-interference ability, stable and reliable to meet the needs of customers, and achieves good economic and social benefits.
