大坝渗流监测系统中电源智能控制子系统的设计与实现

Design and implement of power automatic control system in dam interstitial flow monitoring system

文登市米山水库大坝自动化监测系统由于现场设备一直处于24 h供电状态,使得现场设备故障频发。为了解决这一问题,采用了电源智能控制系统,通过485总线与上位机进行通讯,由上位机对电源系统进行控制,实现了对现场设备的定时、按需、智能供电。经过半年多的使用,取得了良好的效果。

On-site devices failure occurs frequently in automatic monitoring system of Mishan Lake due to the devices on power in 24 hours. To solve this problem, power intelligent control system is added to original system. The power system communicates with the host computer by 485 bus. By this power system, the power supply of on-site devices can be controlled at timing, on-demand and intelligent way. Through more than half a year＇ s running, the power system achieves good effects.
