The Application of the Wireless Sensor Network (WSN) in the Monitoring of Fushun Reach River in China

摘要

The river remote monitoring system in China is manual data collection, the disperse monitoring stations and the lag data transmission. The statistic showed that 90% reach through the city was polluted and 70% lake was eutrophied. So in this paper the Wireless Sensor Network (WSN) in the Monitoring of Fushun Reach Water Quality was studied, which involve the confirmation of polluted sources, Network System construction, the implementation of data transfer system. First Fushun city, as a typical industrial city, is crossed by Hunhe River. A new remote river quality monitoring system based on the wireless sensor network (WSN) design was introduced herein for its low power consumption, long lasting operation time, lower cost, self-communication and ease of implementation in large area. Then the detailed solution concerning system structure, network node, data acquisition process and its remote sensing abilities were discusses. Moreover when the pollution emergencies occur, the environmental department could detect on-time and dispose quickly. But now the some front-end analytical instruments are still in the early stage. At Fushun the current automated water quality sensors can not cover all the important water quality parameters. Manual sampling and laboratory analysis are necessary supplement to the WSN system in order to gather all the necessary data.
