摘要
介绍了单总线数字式温度传感器DB18B20,对其应用于环境温度监测进行研究。分析了该传感器的工作原理及其工程应用中应注意的问题,设计了基于多片DS18B20和AT89C51单片机组成的远距离高精度多点温度数据采集系统。实验室测试结果表明,系统具有测量精度高、抗干扰性强和可靠性高等优点。所设计的远距离高精度多点温度数据采集系统可应用于其他环境较为恶劣的温度监测和控制中。
The 1-wire digital thermometer DS18B20 and its application in environment temperature measurement are discussed. The theory of the DS18B20 sensor and its problems in engineering application are explained first. Then a data acquisition system based on AT89C51 and a few temperature sensors are designed. The lab experiment tests present that the system has the features of high-precision temperature measuring, strong anti-jamming and high dependability. It can be used in temperature monitoring and control under adverse environment.
