水电站水位遥测系统设计与实现

The Design and Implementation of Water Level Remote Measuring System for Hydropower Station

介绍一种利用MPX5000系列压力传感器和V/F转换器设计液位变送器,采用单片机和LED数码管等材料设计和制作具有水位显示和超限报警功能的显示单元。经传输线(或无线通道)实现水电站水库(或前池)水位遥测功能;并连接小水电电网调度微机系统,以提高调度水平和增加经济效益。

This note introduces a design of liquid level detector using MPX5000 series pressure sensor and V/F converter.The display unit which includes microcontroller and LED digital tubes,shows the water level,and warns when exceeding the limit.With transmission line(or radio channel),this system remotely measures reservoir's(or forebay's)water level. By connecting to small hydroelectric network dispatching computer system,it will improve the power management,and bring economic benefits.
