基于FPGA的水质检测系统研究

摘要

In view of problems that present discriminated methods of water burst source can't realize prediction of water burst and has long processing time and high complexity,the paper designed a water quality detection system which adopts laser induce fluorescence technology and uses FPGA as core processor.Through on-line detection of fluorescence spectrum,the system can real-timely monitor changes of chemical components of underground water and rapidly monitor movement precursor of the water burst source,so as to achieve forewarning of water burst.The test results show that the system has high detection precision and fast response speed.%针对目前突水水源的判别方法不能实现突水预警,且处理时间较长、过程复杂等问题,设计了一种采用激光诱导荧光技术、以FPGA为核心处理器的水质检测系统.该系统采用在线检测荧光光谱法实时监测地下水的化学成分变化,从而快速检测矿井突水水源的变化前兆,达到突水预警的目的.试验结果表明,该系统检测精确度高,响应速度快.
