摘　　要：本文介绍了以80C51为控制核心,连同低功耗数字温度传感器AD7416以及PC机构成多点温度测量系统的实现方法。重点描述了AD7416的硬件组成、工作原理以及80C51与AD7416之间的通信方式,并提供了通信中的核心代码。通过实验证明,该系统可以用于温度监控、温度实时采样等场合,具有一定的应用价值。The method of multi -dots temperature measurement system which takes 80C51 as the central- control unit, along with personal computer and low power consumption digital temperature sensor AD7416 is introduced in this paper. The component parts , working principle of AD7416 and the way of communication with 80C51 are especially described in this paper, central code of communication is listed. The experiment result indicates that the system can not only be aplied to the supervision to the temperature and real time sampling, but also has definite value in practice.
