新微波测量线传感技术

A New Sensing Technique for Microwave Line Measurement

根据鼠标的位移矢量传感原理,对国内的微波自动测量线系统加以改进.此系统采用AT89C2 0 5 1单片机的片内比较器,以及单片机的一个I/O口生成PWM波,构成简易的A/D转换器,用PC机实现数据的存储处理.系统小巧易用,方便快捷,克服了国内微波自动测量线系统体积大,测量距离受限制等弊端.

The system indicated below bases on the theory of bit-shift sensor of mouse.Some improvement has been made for the domestic microwave measuring line system.It uses the comparator of AT89C2051 single-chip microcomputer as A/D interface and utilizes computer as data storage and transaction tool.The characteristics of this system are smart,small,convenient and time-saving.Therefore,it avoids the defects such as big bulk and limited measuring distance etc.which the other systems have in our country.
