Study on Urban Underground Waterlogging Monitoring and Warning System Based on Internet of Things and GIS

为了实现城市地下空间内涝监测预警,介绍了基于物联网与GIS的城市地下空间内涝监测预警系统。分析了该系统的网络结构、传感器模块以及内涝参数处理算法和后台监控系统。多种传感器并用,提高精度,支持手动报警开关,可实现实时报警,并大大地降低了误报率和漏报率。在对目前城市地下空间内涝防治的基础上,总结了各类城市地下空间内涝防治的主要方法,对城市地下空间内涝防治的未来进行展望,并将新的技术结合应用在内涝防治中。实测表明,该系统不仅稳定可靠、抗干扰、能耗低,而且监测精度和灵敏度高,是一种城市地下空间内涝监测报警系统的新技术,将提高城市安全保障水平。

In order to realize the monitoring and early warning of urban underground space waterlogging,this paper introduces the monitoring and early warning system of urban underground space waterlogging based on Internet of Things and GIS.The network structure,sensor module,waterlogging parameter processing algorithm and background monitoring system are analyzed.The combination of multiple sensors can improve the accuracy and support manual alarm switch,which can realize real-time alarm and greatly reduce the false alarm rate and missed alarm rate.Based on the current prevention and control of waterlogging in urban underground space,the main methods of waterlogging prevention and control in various types of urban underground space are summarized,and the future of waterlogging prevention and control in urban underground space is prospected space,and applies new technologies to waterlogging prevention and control.The measured results show that the system is not only stable and reliable,anti-interference,low energy consumption,but also high monitoring accuracy and sensitivity.It is a new technology of urban underground space waterlogging monitoring and alarm system,which will impr ove the level of urban security.
