摘要
本文针对灌溉渠道使用的雷达液位计开发了一套软件系统,通过软件采集雷达差频信号,对采集到的信号数据进行加窗处理、快速傅里叶变换、液位计算和传输液位信息。实现了对灌渠液位实时的测量,并将探测到的液位信息发送给远程计量门的控制系统。
A software system was developed for the radar level meter used in the irrigation channel. The radar difference frequency signal was collected by the software , and the signal data collected were processed with Windows , fast Fourier transform , liquid level calculation and liquid level information transmission.The real- time measurement of liquid level in irrigation canal is realized and the detected liquid level information is sent to the control system of remote metering gate.
