　　Abstract：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.
