摘　　要：建立了水质自动监测系统,监测参数包括:pH、温度、电导、氨氮、溶解氧、生化耗氧量、化学耗氧量、总有机碳、总氮、总磷、叶绿素和矿物油。该系统依托GSM无线网络,基于GPRS技术应用HY水质监测管理系统软件(HY-WQMS)实时获得最新数据以及运行状态,当监测数据超过报警门限或仪器发生故障时,系统自动向用户发送报警信息。监测子站各水质分析仪通过RS-485总线和通讯控制单元RTU相连,实现系统集成。建立了断面采样系统和多点采样系统。该系统准确性高,各参数比对的相对误差在0.2%～8%之间,稳定性好,连续测定的相对标准偏差在0.78%～4.97%之间,符合自动分析仪的技术要求。The water quality automatic monitoring integration system is presented in the paper. The parameters to be monitored include ： pH, Temperature, EC, NH3 -N, DO, BOD, CODcr, TOC, T-N, T-P chlorophyll and mineral oil. The software of HY-WQMS is developed for water quality management. The data are received from internet online by the HY-WQMS software. The system will send an alarm message on GSM when the water pollution goes over a limit or some instrument is out of order. The instruments for water quality analysis are integrated through RS-485 and RTU. The data of water quality by automatic monitoring are transferred by means of GPRS technology. The study results show that the accuracy and precision of the integration system are sufficiently high. The relative error is 0.2 % - 8 %, and the relative standard deviation is 0.78% - 4.97%. The high accuracy and precision can meet the technical requirement of the water quality automatic monitoring.
