Embodiment 1

[0039] Such as figure 1 As shown, the present invention consists of sensor nodes 101 of various types of sensors, cluster head nodes 102 and convergence gateway 103 to form a wireless sensor network for comprehensive monitoring of sudden floods in mountainous areas. The types of sensors used mainly include: rainfall, soil moisture content, infiltration Coefficient, slope displacement, water level and flow sensor; The wireless sensor node of the present invention is deployed in monitoring area as Figure 5 As shown, according to the GIS information of the monitoring area, the distribution characteristics of the hillside rainfall and the geological information of the hillside, the node deployment position of the area is calculated, and the position of each node is marked in the GIS. 503, flow sensor 504, slope displacement sensor 505, and then the aggregation gateway 103 is deployed on the top of the mountain in the center of the monitoring area, so that the transmission distanc...

Embodiment 2

[0043] The node layout is the same as in Example 1, the comprehensive monitoring and disaster early warning method for sudden floods in mountainous areas. Second, lease GPRS and Internet public network to form a communication subsystem, use existing public resources to realize remote monitoring, avoid unnecessary increase and waste of system costs caused by self-built private network, and existing GPRS and Internet The mature performance of Internet public network technology is reliable; then the information fusion technology is reasonably selected and applied to solve the problem of large amount of information and complex relationship faced in the comprehensive monitoring and disaster warning system of mountainous area sudden flood of the present invention, so that various factors that can induce mountain torrent disasters comprehensively (mainly rainfall, topography and geological conditions), real-time and reliable dynamic situation assessment and early warning information o...

Abstract

The invention discloses a monitoring and prewarning system for sudden flood in a mountainous area and an establishing method thereof. The monitoring and prewarning system comprises a plurality of field monitoring wireless sensor networks and a monitoring system, wherein the field monitoring wireless sensor networks and the monitoring system transmit information through a GPRS (General Packet Radio Service) network and Internet, each field monitoring wireless sensor network comprises a plurality of sensor nodes, a cluster head node and a converging gateway, the sensor nodes are arranged in a monitored region and connected with the converging gateway through the cluster head node and transmits monitored information to the converging gateway, and the converging gateway transmits the information to a monitoring computer through the GPRS network and Internet. The monitoring and prewarning system disclosed by the invention can well meet real-time and rapid acquiring of monitoring field data in monitoring and management on disasters, such as flood, landslide and debris flow.

Description

technical field [0001] The invention belongs to the technical field of real-time monitoring and early warning of natural disasters, in particular to a sudden flood monitoring and early warning system in mountainous areas and a construction method thereof. Background technique [0002] my country's mountainous area accounts for about 2 / 3 of the country's land area. It is mainly located in the East Asian monsoon region. The terrain, landforms, and geological conditions are complex and diverse, and the climate factors are complex and changeable. In addition, the population is dense and the impact of human activities is high. Induced sudden floods in mountainous areas occur frequently, causing a large number of casualties and property losses every year. It is one of the main disasters caused by natural disasters in my country. [0003] Establishing a mountainous flood monitoring and disaster early warning system is an important non-engineering measure for the country to prevent a...
