The Baisha Lake Water Quality Monitoring System Using Wireless Sensor Networks

In this paper,in Baisha lake of the Nanji wetland national wetland reserve, through the application of wireless sensor network technology, database technology and statistical methods we built a water quality monitoring system. We studied how to eliminate the interference of the abnormal values in the monitoring. This study was carried out basic research work of the water quality monitoring in the Nanji wetland national wetland reserve. The main contents of this paper are as follows:1. We designed and implemented an effective water quality monitoring system that using wireless sensor network technology in the Baisha lake, an effective water quality monitoring system. The results show that this water quality monitoring system can effectively deal with the high complexity of the hydrodynamic characteristics in the Baisha lake.2. We developed a water quality monitoring software system with C# and SQL server. The user can view the Baisha lake water quality of real-time data and historical data and to guarantee the data security.3. As automatic water quality monitoring data need quality control, the data quality control of the monitoring system from the point of view of the sensor maintenance was developed. Through comparison of field-based sampling data and statistical analysis, we demonstrated that the conductivity data by changing the maintenance cycle can be effectively guaranteed in the monitoring system in Baisha lake.The system completed the quality of multi parameter information real-time acquisition, data quality assurance, safe data storage and visualization, the water quality monitoring system provides a monitoring scheme for Poyang lake water with enjoyed high practical use value.
