Distributed wireless sensing network system used for lake water quality monitoring

Abstract

The invention relates to a distributed wireless sensing network system used for lake water quality monitoring, which comprises the technical scheme as follows: the system comprises n nodes and a base station (4); the n nodes consist of a coordinator (3), at least one terminal (1) and at least one router (2); the nodes are distributed in the way that the router (2) and the coordinator (3) in a certain monitoring area in a lake firstly and then the terminal (1) is arranged near the router (2) and the coordinator (3); and all the nodes form the wireless sensing network through a wireless self-organizing way. Besides the control software written in ROMs (read only memory) of microprocessor control modules (14) of the nodes are different, the rest structures of the nodes are the same. The distributed wireless sensing network system used for the lake water quality monitoring has the advantages of real-time dynamic monitoring, low cost, less energy consumption and large monitoring area, andis simple and easy for monitoring, etc. When the distributed wireless sensing network system used for the lake water quality monitoring is applied to actual environments, the existing domestic current environment monitoring technologies and systems are expanded, optimized and perfected, and the distributed wireless sensing network system provides powerful technical supports for dynamically monitoring water environment quality in real time.

Problems solved by technology

[0008] The first method belongs to the traditional monitoring method, the sampling period is longer, and the sampling time is greatly affected by many factors such as water terrain and weather

Although the second method overcomes the shortcoming of long sampling period and difficult sampling in the first method to a certain extent, it uses wired transmission, and the cost of cables and cable laying is relatively high. shore waters

The third method is greatly affected by the terrain and landform during telemetry, and is suitable for monitoring large-scale waters of oceans and lakes, and the operation process requires coordination and cooperation between multiple departments. The process is often lengthy and complicated, and it is not easy to implement.
