Problems solved by technology

At present, the most widely used method in China is still the off-line monitoring method, but this method generally has defects such as large sampling error, high labor intensity, low monitoring frequency, scattered monitoring data, and inability to provide real-time feedback on continuous and dynamic changes in water environment conditions. Relevant government department supervision and enterprise's own monitoring needs

Abstract

The invention relates to a multi-parameter online water quality monitoring system and method based on a wireless sensor network. The system comprises at least three multi-parameter water quality monitoring buoy nodes, at least three convergence nodes, a gateway node and a monitoring center or a data service end, wherein a multi-hop self-organized network formed by the multi-parameter water quality monitoring buoy nodes is connected with the convergence nodes; a multi-hop self-organized network formed by the convergence nodes is connected with the gateway node; the gateway node is connected with the monitoring center or the data service end. The system is high in expandability and convenient to maintain and repair, monitors data on line in real time, and provides reference data and basis for fresh water pollution.

Description

technical field [0001] The invention relates to a water quality monitoring system and method, in particular to a wireless sensor network-based multi-parameter water quality online monitoring system and method, belonging to the technical field of wireless sensor network and smart water affairs. Background technique [0002] In recent years, with the continuous development of industrialization, regional economy and the acceleration of urbanization, the problem of water pollution has become increasingly prominent, seriously affecting the safety of drinking water for urban and rural residents, thus further aggravating the urban water shortage. According to the statistics of the State Environmental Protection Administration, due to the excessive discharge of urban sewage and industrial wastewater, the river sections where surface water flows through large and medium-sized cities are often the most polluted. Although governments at all levels are vigorously promoting pollution sup...
