城市水文防汛预警系统实现和应用

Implementation and Application of Urban Hydrological Flood Warning System

根据城市水文防汛具体要求,提出了水文防汛监测预警系统设计理念,认为应由监测系统、通信系统、前台监测设备和测量系统四部分组成,发挥分类管理、数据搜集、数据分析、预警、查询、存储和通信等功能,并进一步简述了激光水位计在城市水文防汛系统中的适用性及监测设备的安装方法.通过系统上线运行情况来看,系统功能比较完善、运行平稳,能够为防汛部门提供一手降雨量信息与预警信号提示.

Due to the changing climate environment and frequent extreme weather,urban water logging caused by heavy rain becomes a serious threat,affecting the normal production and life of the urban residents.Therefore,how to strengthen urban hydrological flood monitoring and early warning forecast is increasingly imminent.According to the detailed requirements of urban hydrological flood control,the design idea as to the hydrological flood monitoring and warning system is proposed,composed with monitoring system,communication system,front monitoring device and measuring system in charge of systematic management,data compilation,early warming,information inquiring,storage and communication.The applicability of laser water level gauge in urban hydrological flood control and the installment method of measuring device are introduced briefly.The trials are perfect and smooth,providing first-hand information of rainfall and early warning signal for flood prevention department.
