1、中文摘要 I 摘摘 要要 温度是工业、农业生产中常见的和最基本的参数之一，对其进行适时准确的 测量具有重要意义。传统的温度测量系统不仅要设计信号调节电路，还要经过复 杂的标准和标定工程，其测量精度难以得到保证，而且测量方式周期长、施工复 杂，效率低，不便于管理，发生故障时，要耗费大量的人力物力排查和重新铺设 线缆。因此设计一种低功耗的无线温度检测系统很有意义。本文提出一种采用单 片机 STC89C52RC 控制 DS18B20 实现的无线温度测量系统。通过简单的无线通信 协议，实现可靠性与功耗平衡，该系统能实现对温度的检测,基于无线传输的系 统。低功耗、实时性的无线温度检测是该设计的最大特点。
