Wireless sensor network-based river basin pollution monitor system and method

Abstract

The invention relates to a river water quality detect system and a relative method, based on wireless sensor network, belonging to environment protective technical field. The system is composed of a water quality information collecting node, a relay node, a detect base station, and a remote server, wherein the delay node and the detect base station form a chain wireless network, the information collecting node is in the network with nearby delay nodes, to form a wireless sensor network to pickup the pollution information of river and send information to the base station, the base station collects the picked data, via wire network to be transmitted to a remote server. The invention can pick water quality information, detect pollutant real-time, and alarm over pollution, while the network information is collected to the remote server to be intelligently managed, to analyze the water quality information. The invention realizes water quality detection, to obtain the pollution information and execute relative operation to manage the pollution.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a river basin pollution monitoring system and method based on a wireless sensor network. Background technique [0002] Environmental pollution has become a global problem, among which water pollution has a huge impact on people. Pollution of a river will have a serious impact on the vast basins that the river flows through, seriously disrupting people's lives and causing huge losses to the national economy. [0003] Organic pollution is common in major rivers in China, and non-point source pollution is becoming increasingly prominent. The Liaohe River and Haihe River are seriously polluted, the Huaihe River is poor in water quality, the Yellow River's water quality is not optimistic, the Songhua River's water quality is fair, and the Pearl River and Yangtze River's water quality is generally good. Eutrophication of major lakes is serious. [0004] In 2002, amo...

Problems solved by technology

[0007] The main problems in my country's current water pollution monitoring system: First, the water quality monitoring equipment has a low degree of automation and poor real-time performance, and cannot monitor water pollution around the clock; It is not suitable for large-scale installation and application; the third is that the system networking technology is single, usually only using wireless local area network technology to form a bus structure, and the emerging ad hoc network technology solutions have not been applied and reflected, and long-distance data transmission cannot be realized

For example, the Chinese patent "Water Quality Online Monitoring Network System" with the publication date of May 14, 2003 and the publication number CN1417588A uses a central computer, a base station computer and an online monitor, and the central computer and the base station computer are connected on the Internet via a modem. The base station computer and the online monitoring instrument are connected through the extended serial port. This patent provides a simple, low-cost, and feasible solution for network construction, and can monitor water quality parameters in real time and flexibly. However, it is a wired connection and requires Manual intervention, low degree of automation

In addition, the Chinese patent "Environmental Protection Water Quality Remote Monitoring and Alarm System" with the publication date of June 8, 2005 and the publication number CN1625110A provides a wireless solution, but uses a general-purpose wireless local area network in the form of networking Simple, not well implemented for long-distance and large-scale data transmission
