Dissolved oxygen monitoring system based on wireless sensor network

Abstract

The invention provides a dissolved oxygen monitoring system based on a wireless sensor network. The dissolved oxygen monitoring system comprises a dissolved oxygen monitoring control center, a plurality of wireless dissolved oxygen measuring nodes and a converging node, wherein the signals of the plurality of wireless dissolved oxygen measuring nodes are transferred to the dissolved oxygen monitoring control center through the converging node. Based on the wireless sensor network technology, the dissolved oxygen monitoring system provided by the invention has the advantages that the can realize monitoring of dissolved oxygen at any time and any place in the coverage area of the wireless sensor network can be realized, operation is simple and convenient in operation, saves a lot of manpowerand material resources are saved and improves the dissolved oxygen monitoring efficiency is improved.

Description

technical field [0001] The invention relates to the field of water quality monitoring, in particular to a dissolved oxygen monitoring system based on a wireless sensor network. Background technique [0002] Water quality monitoring is the process of monitoring and measuring the types of pollutants in the water body, the concentration and change trend of various pollutants, and evaluating the water quality status. The scope of monitoring is very wide, including unpolluted and polluted natural water (river, river, lake, sea and groundwater) and various industrial drainage. [0003] Due to the particularity of water quality monitoring, when it is necessary to check the measurement data after water quality monitoring in a large area of ​​water, the more common method in the prior art is to retrieve the sensor and export the data in the laboratory, which makes it extremely inconvenient to use. Another system is to network the sensors and transmit the data to the host computer th...

[0003] Due to the particularity of water quality monitoring, when it is necessary to check the measurement data after water quality monitoring in a large area of ​​water, the more common method in the prior art is to retrieve the sensor and export the data in the laboratory, which makes it extremely inconvenient to use. Another system is to network the sensors and transmit the data to the host computer through the 485 bus. However, this system needs to set up a large number of data lines in the water. Although it is more convenient to view the measurement data, the system installation is not convenient.
