System and method for real-time hydrologic monitoring and transmission based on wireless sensor network

Abstract

The invention discloses a method for real-time hydrologic monitoring and transmission based on a wireless sensor network. A system comprises a plurality of water surface nodes and a data terminal, the water surface nodes include general nodes and a hub node with a telecommunication function, the general nodes are used for acquiring underwater sensor data, the underwater sensor data are compressed and sent in a free wireless communication manner, an ad hoc network among the nodes converges information to the hub node, the hub node sends the information to the data terminal by means of charged wireless communication or satellite communication, and the data terminal has the functions of data processing, data storage, warning judgment, warning information sending and the like. The system and the method can be used for long-term observation of underwater physical, chemical and biological parameters in the field of scientific investigation, can be used for environmental monitoring and pollution warning of riverways and coastal waters and forecasting of disasters such as flood, tsunami and red tide, and have the advantages of low equipment cost, low communication cost, capability of achieving long-term continuous use and avoiding data to be tampered, high automation degree, no secondary pollution and the like.

Description

technical field [0001] The invention relates to an underwater monitoring method, in particular to a real-time hydrological monitoring transmission system and method based on a wireless sensor network. Background technique [0002] With the rapid economic development and the rapid improvement of industrialization, while bringing many conveniences to life, sewage and gas emissions have brought negative impacts on the environment. In particular, inland rivers and coastal waters are most affected because they are closer to the land, and the pollution of the water environment and atmospheric environment will have an impact on the global ecosystem and climate system in the next few decades or hundreds of years. In addition, natural disasters in inland rivers and near seas threaten the production and life along the coast at any time. [0003] At present, the detection methods for underwater environmental information mainly include: 1) satellite remote sensing; 2) radar monitor...

AI Technical Summary

Problems solved by technology

However, due to the influence of river courses and coastal areas on human life and production, the time and space are complex and changeable, it is impossible to meet the demand only by relying on these regular and fixed-point observation densities

For severe pollution incidents or natural disasters, failing to give early warning will cause serious emergency losses and even casualties
