Research On Multi-parameter Water Quality Monitoring Equipment And Multi-layer Monitoring Station

With the rapid development of China's economy,industry and agriculture,the pollution problem of water source reservoir is becoming increasingly serious,and along with the people's pursuit of higher quality of life,the cleanliness of water resource in water source reservoir becomes more and more concerned by the society.Regular and long-term water quality monitoring of reservoirs is a necessary way to ensure good water quality of reservoirs.However,the existing water quality monitoring methods often use manual sampling and laboratory analysis methods,which are inefficient.The existing water quality monitoring equipment can't monitor the vertical water quality distribution effectively.Therefore,it is urgent to develop a water quality monitoring system which is easy to use and can efficiently collect the vertical water quality distribution of reservoirs.Based on the demand for monitoring the vertical water quality distribution of water source reservoirs,this paper aims to improve the efficiency of vertical water quality data collection.In view of the need of long-term monitoring of vertical water quality distribution in reservoirs and the problem that existing monitoring stations can only monitor surface water,a multi-parameter water quality monitoring station is designed in this paper.According to the designed portable multi-parameter water quality monitoring system,this paper has made the sensor module and separately developed the upper computer of the monitoring system based on C# and embedded Qt,and introduced the sensor selection,hardware structure design and the development details of the upper computer in detail.Then,according to the designed multi-parameter water quality monitoring station,this paper develops a vertical multi-layer multi-parameter water quality monitoring station system.The practical application results verify the rationality and effectiveness of the system designed and developed in this paper.The water quality monitoring system has been successfully used to collect water quality data in vertical distribution of the reservoir.
