山东省环境水质自动监测网运行管理系统研究

文章对水质自动监测站远程监控和反控、监测数据的自动审核、现场维护行为的评判及水质自动监测网的统一管理等问题进行了研究。通过对水质自动监测站现场工控机PLC的升级改造、对各单元和部分监测仪器加装传感器,实现了对系统和仪器设备关键节点运行状态参数的全方位实时调取。根据实际需求研发了系统管理软件,实现了区域环境水质自动监测网统一的信息全方位采集与多级传输,运行状态参数的远程监控与反控,监测数据有效性的自动判别与自动审核,监测信息的在线查询发布与管理,运行维护绩效的自动评估和系统一站式管理。目前该系统在山东省得到了全面应用,保证了监测数据的准确性、可比性与时效性,为实现水质安全预警提供了技术保障,为各级政府制定环境水质改善措施提供了科学依据,收到了显著成效。

Operation Control and Information Management System of Shandong Province Environmental Water Quality Automatic Monitoring Network

Studies and researches were done concerning issues like remote monitoring and counter-monitoring of water quality automatic monitoring station,automatic audit of monitoring data,evaluation upon onsite-maintenance behavior,as well as centralized management of water quality automatic monitoring network.The comprehensive and real-time collection of running status parameters from the system and instrument essential points can be realized through updating & rebuilding of water quality automatic monitoring station onsite public computer(PLC),and adding electrodes to each unit and part of monitoring instruments.System management software was developed based on the actual demand,which enabled the comprehensive collection and multi-level communication of unified data from regional environmental water quality automatic monitoring network,remote monitoring and counter-monitoring of the running status parameters,automatic diagnosis and audit to the effectiveness of monitoring data,online query,release and management of the monitoring information,automatic assessment and system one-stop management upon operation and maintenance performance.Currently,this system has been widely applied in the Shandong Province and already achieved a remarkable accomplishment,which guarantees the accuracy,comparability and timeliness of monitoring data,provides technical safeguard for early warning of water quality safety,and offers scientific basis for environmental water quality improving measures designed by various government levels.
