The design of rainfall monitoring and warning system based on GIS

摘要:

为了解决在汛期阶段，由过量降雨引发的震裂带山体崩塌问题，设计一种基于GIS的震裂坡地降雨量监测预警系统。按照GIS平台的开发标准，连接WebApp构件与其它硬件模块设备，完成震裂坡地降雨量监测预警系统的概要设计。在此基础上，根据震裂坡地质环境条件、气象水文特征和其它性能统计结果，完成监测预警系统的主要需求分析。再通过分析监测预警系统组成与GIS体系结构的方式，处理常规GIS体系的巡检操作功能，实现震裂坡地降雨量监测预警系统的顺利应用。实用测试结果表明，应用监测预警系统后，震裂坡地降雨量空间插值的最大数据结果不超过4.0×1017T，降雨区域的危险性等级也出现明显下降，汛期过程中存在的震裂带山体崩塌行为得起有效控制。

Abstract:

In order to solve the problem of mountain collapse caused by excessive rainfall during flood season, a GIS based rainfall monitoring and warning system for earthquake cracked slope was designed. According to the development standard of GIS platform, WebApp components and other hardware module equipment were connected to complete the summary design of rainfall monitoring and warning system of seismic crack slope. On this basis, according to the geological environment conditions, meteorological and hydrological characteristics and other statistical results, the main requirements of the monitoring and warning system are analyzed. By analyzing the composition of the monitoring and warning system and the structure of the GIS system, the routine GIS system is processed to realize the smooth application of the rainfall monitoring and warning system on the cracked slope. The practical test results show that after the application of the monitoring and early warning system, the maximum data of spatial interpolation of rainfall in the cracked slope is no more than 4.0×1017T, and the risk level of the rainfall area is also significantly reduced. The collapse behavior of the mountain in the cracked zone during the flood season should be effectively controlled.
