在空间多传感器温度测量中，由于温度探测器多，因此快速测量是基本要求。本文分析了数字温度传感器DS18B20的特性，分析计算了温度测量时间和数据读取时间，在此基础上，设计了传感器驱动电路和数据读写时序，提出了新颖的串并结合的多传感器分布式空间温度测量技术方案，实现了每路10个DS18B20数字温度传感器同时启动，分时读取数据，8路并行的多点温度快速测量。同点温度测量标定实验和实际空间的温度分布测量的实验结果良好，说明方案具有可行性和优越性。

Fast measurement is a basic requirement for spatial multi-sensor temperature measure-ment since many sensors are needed. Based on the analysis of the digital temperature sensor DS18B20’s characteristics, its temperature measurement time and data access time, the sensors’driver circuit and data access time sequence were designed. In this design, a novel method of distributed spatial tempera-ture measurement was proposed. The system contains 80 sensors with 8 buses in parallel and 10 sensors on each bus. Those 80 sensors start measurement simultaneously and the 8 buses read the measurement data in parallel. The good results of experiments on same-point-temperature measurement and actual spatial-temperature-distribution measurement illustrated the feasibility and advantages of this system.
