摘　　要：城市供水的管网压力是供水调度最重要的指标之一。随着信息化技术的提升,管网压力在线监测能准确反映某一时刻的供水服务情况。当在线压力监测点达到一定规模时,仅依赖传统的单点报警分析方式已无法满足现有突发事件应急处置及时响应的要求,因此须构建具有联动特性的管网区域评价模式,为管网统筹调度优化提供相关基础。文中根据上海中心城区供水管网在线压力监测点分布及运行的特征,对建立具有联动特性的区域管网报警开展探索性研究,并投入实践辅助调度,虽然关联方法还不够完善,致使产生一定的误报率,但仍取得了一定的应用效果。Urban water supply pipe network pressure is one of the most important indicator of water supply control. The network pressure real-time monitoring can accurately reflect the situation of water supply at a time with the development of information technology. When the online pressure monitoring points reach a certain size,depending only on the traditional single point alarm analysis methods has been unable to meet the requirements of existing emergency disposal timely response. It is necessary to construct linkage characteristics of the regional pipeline network evaluation model,which is the basis provided for the optimization of the overall network control system. According to the characteristics of Shanghai central city water supply network online pressure monitoring points’ distribution and operation,this paper carry out exploratory research established with linkage characteristics of the regional network alarm,and put computer aided control into practice. Although the correlation method is still not perfect and may produce a certain false alarm rate,but it still takes a certain application effect.
