摘要:
基于目前我国地表水水质自动监测现状,初步探讨了地表水水质自动监测预警方法体系,提出了水质自动监测预警的整体技术路线,搭建基于突变型预警和渐变型预警的多种预警模型组框架,可以实现对单因子、多因子组合,趋势、状态等不同情况的异常水质数据进行预警,保证了预警的可靠性和准确性。通过实例分析,从水质自动监测数据集成、异常数据判定清洗、预警模型建立与运行、预警信息处理等方面介绍了水质自动监测预警的实现方法。

Abstract:
Based on the current status of Chinas surface water quality automatic monitoring, the current paper preliminarily discussed the early warning method system of surface water quality automatic monitoring. The overall technical route of early warning on automatic water quality monitoring has been put forward, and a variety of early warning model group framework has been built based on sudden change type early warning and gradual change type early warning, which can realize the single factor, multi factor combination, trend, status and other different cases of abnormal data early warning, so as to ensure the reliability and accuracy. Finally, the implementation of early warning method of water quality automatic monitoring was introduced through the examples such as integration of the water quality automatic monitoring data, determination and cleaning of abnormal data, establishment and operation of early warning model, process of early warning information and other aspects.
