摘　　要：水资源短缺和水污染的日益严重,如何建立一个高效完善的地表水监控系统成为亟待解决的问题[1]。本系统结合嵌入式web服务器、GPRS技术以及嵌入式技术,应用快速消解-分光光度法实现对地表水COD值的实时监测[2-4]。用户可通过网络远程控制设备开闭、设定监测设备相关参数、在线查询COD值以及开启摄像头监控现场情况。COD在线监测系统通过6组标样值拟合出回归曲线,每次COD检测都会进行标定,保证了COD数据值的可靠性,经测定COD在线监测系统具有较高的准确性和可靠性,有较高的市场价值。Facing shortage of water resources and water pollution increasingly serious,how to build an efficient perfect surface water monitoring system become serious problems to solve. Combining with embedded web server, GPRS technologies and embedded technology, the fast digestion-spectrophotometry was used to realize real-time monitoring of surface water COD value. Users can control the equipment, set related parameters of monitoring equipment, inquire online COD value and open the surveillance camera through the network remote. COD online monitoring system drafts the regress curve through the six groups themselves value, every time COD detection will calibrate, and guarantee the reliability of the value about COD data. Through the determination of COD, the online monitoring system has high accuracy, reliability and the high market value.
