Design and application of the integrated sound and photoelectric early warning system for flash flood monitoring

为解决山洪监测预警能力不足的问题,结合山洪成灾特点,在分析目前山洪监测预警系统存在主要问题的基础上,利用当前先进数字和物联感知技术,依托数据分析算法,采用水位和雨量模块化设计思路,设计和研发山洪监测声光电一体化预警系统。搭建以水位监测、雨量监测、视频监控、预警广播为一体的监测预警系统结构框架,能够显示实时水位、雨量等数据,根据水位和降雨量的预警阈值自行演算进行现地预警,并且能够将采集数据、图像及预警信息传输到云端。基于及时、准确、可靠的山洪监测声光电预警一体化系统,切实提高山洪灾害全天候、全过程的监测预警能力,在实践应用中预警系统适用于沟渠、河道等多种场景,具有实时监测数据准确、预警精度高、预见期足够、预警设备适用性强等优点。

In order to solve the problem of insufficient capacity of flash flood monitoring and early warning,the main problems existing in the current flash flood monitoring and early warning system are analyzed considering the features of flash flood disasters.By applying the advanced digital and sensing technology,an integrated sound and photoelectric early warning system for flash flood monitoring is designed with modules of water level and rainfall,and developed based on data analysis algorithm.The system is set up with an integrated framework of water level monitoring,rainfall monitoring,video monitoring and early warning broadcasting,which can display real-time water level,rainfall and other data,and can automatically calculate the local early warning data according to the warning threshold of water level and rainfall,and then transmit the collected data,images and early warning information to the cloud.Based on this timely,accurate and reliable system,the monitoring and early warning capacity of flash flood disasters in all weather and in the whole process is effectively improved.In practical,the early warning system is applicable to various scenarios such as ditches and rivers,and has several advantages,including accurate realtime monitoring data,high warning accuracy,sufficient forecast period,and strong applicability of early warning equipment.
