Application Of WSN In Hydrologic And Hydraulic Monitoring

The wireless sensor network is a distributed sensor network whose peripherals are sensors that can sense and examine the external world.Sensors in wireless sensor networks have a variety of goals,functions and capabilities.This area is currently undergoing recent advances in technological advances and numerous potential applications.With the development of society,the rational use and protection of water resources has become an increasingly important issue.One of the highlights.Improve the water and rain monitoring system,the development of the country and society is important for the rational use of water resources,flood control and drought,to ensure the development of agriculture to provide an important guarantee.Wireless sensor network technology has a fast,macro,cross time,systematic large-scale survey,monitoring the advantages of water and rain within the region.Scientific and rational restoration and reconstruction of the ecosystem in the region,and it is of great significance for urban and rural flood control and drought resistance.Through the investigation of the surrounding environment of tianshengqiao reservoir,the method of wireless sensor network was adopted,and the automatic measurement system of water and rain of tianshengqiao reservoir was designed.The system can improve the efficiency of water use in flood control and power generation scheduling.Water and rainfall regime the natural arch reservoir of wireless sensor network(WSN)is a system consists of sensor nodes,the transmission channel and the center node river hydrologic monitoring system based on wireless sensor network(WSN),the system can real-time monitoring around the reservoir and water level information.The water and rain sensor network system consists of sensor node,transmission channel and central node system.From the analysis of information acquisition,information transmission and processing process,these three subsystems are at different levels of the whole system and undertake different tasks.Among them,the sensor node is located at the bottom of the system,and undertakes the data collection task of the station in the basin.The communication system is between the sensor node and the center node,responsible for the transmission of information between them;The center node is at the top of the system and is responsible for system control and data processing.The whole system network topology is basically the star structure that is common in the water situation system: the sensor node and its corresponding central node formthe star network.
