自动抄表系统中几种传感器的应用

Application of Several Sensors in Automatic Meters-reading System

简要介绍了自动抄表系统的基本原理和采集部分的设计思路,着重介绍了光电传感器、霍尔传感器和零功耗磁敏传感器及其检测电路在自动抄表系统中的应用,并对它们的优缺点进行了比较。

The basic theory of automatic meters-reading system and the design idea of data acquisition in automatic meters-reading system are introduced. Not only the Application and compareison of the photoelectric sensor and the hall sensor and the zero exploit magnetic sensor and their measureing circuits apply to the automatic reading meters system are introduced, but also the merits and the shortcoming of them are compared.
