机房漏水检测与精确定位装置研究

摘要

Water leakage is a major security risk which endangers the long-term stable and reliable operation of precision in-formation equipment in the room. In order to solve the problem that the traditional positioning device has in realizing the accurate positioning of water leakage point,this paper designs a room water leakage detection and positioning device which combines three functions:self-detection,water leakage detection and positioning by using the detecting principle of sensor cable water leakage,par-tial voltage compensation principle and STEP 7 software programming. We build an experiment system. Test results show that short distance positioning accuracy rate can reach 1.70%and confirms the effectiveness and accuracy of the device detection and posi-tioning.%机房漏水是危及精密信息设备长期稳定可靠运行的重大安全隐患。为了解决传统定位装置难以实现漏水点精确定位的问题，从传感电缆的检漏原理出发，利用分压补偿原理，通过STEP 7软件编程，设计了一个结合自检、漏水检测和漏水定位3种功能的机房漏水检测与定位装置。在此基础上搭建了实验系统，经测试实验，结果表明短距离定位精度可以达到1.70%，从而证实了该装置检测的有效性和定位的精确性。
