摘　　要：目前大区域水质分析依赖人工取样或监测水质的化学成分变化情况,但该方法存在监测区域较小、分析周期长、监测数据滞后等现象,为了解决该问题,提出了一种大区域水质污染实时监测系统,系统由移动数据采集终端,中心数据处理终端组成;给出了详细的硬件和软件的设计方案,其中数据采集终端通过YSI6600水质传感器复杂水质电信号采集、滤波、A/D变换等工作;信号处理终端采用处理能力较强的S3C2410核心芯片,处理大区域水质采集的大量电信号,在软件设计方面设计了一种水质信号残差修复算法,解决由于区域过大发生的电信号失真的弊端;以VB6.0为基础进行的系统集成测试表明,系统在3.5平方千米内的数据测试中,污染检测的精度达到77%,高于人工检测平均水平的65%,延时不超过0.7s/km,优于传统的水质监测系统。The current water quality analysis system, rely mainly on the chemical composition of water quality monitoring, the system widely exist monitoring cycle is long, signal lags behind, the monitoring area is too small, such disadvantages as. In order to solve these problems, the article proposes a kind of based on S3C2410 - GPS technology of large area water quality intelligent monitoring system design method. Instrument used processing ability strong S3C2410 core chip processing large area water quality of signal acquisition, and guarantees the system of real time, design the acceleration sensor network eliminate signal transmission of the reaction time delay, design the residual repair pollution evaluation algorithm, guarantee the accuracy of the pollution sources detection. Later system integration tests show that, the actual control area of the system reached 3.5 square km. Detection accuracy reached 77%, higher than the artificial level of 65%. Delay no more than 0. 7 seconds/kin and superior to the traditional water quality monitoring system.
