The Design And Implementation Of Collecting System For Field Water Samples

In recent years,with the development of the scale of industry and agriculture in our country,environmental pollution,especially water pollution is intensifying.Among which,Water pollution in some areas seriously restricts not only the economic development,but also pose a threat to the health of people.The safety of Water resources has attracted an increasing attention.In order to solve the problems of water pollution well,establishing the field water environment monitoring and sampling system by using the latest technology so as to provide the real-time monitoring and protection for water environment,and avoid the occurrence of water disasters in time,besides the sewage treatments.This is also important for the scientific and reliable protection of water quality to provide accurate and reliable basis.Based on the analysis and research on the monitoring and collection system of the field water samples at home and abroad,this paper puts forward a field water quality monitoring and sampling system in order to solve the shortcomings of the traditional field water samples.Traditional field water samples need the manual manipulate.Artificial operations have great influence on water samples,which also decreases the sampling reliability,and cannot complete the fixed-point,fixed-timing,fixed-deep sampling.The main contributions are as follows:1.This paper firstly analyzes and studies the functional flow and existing shortcomings of the traditional field water sampling system,the latest automatic control technology in the industry is used in order to solve the problem that the traditional field water samples requires manual intervention,which may influence the results of water sampling.At the same time eliminating manual intervention from the field water samples,it raises the accuracy and reliability of water quality monitoring and sampling,and it also presents the opportunities to monitor and sample water in extreme or special water environments where labor is difficult or impossible to reach.2.The field water quality monitoring and sampling system,which is presented in this paper to achieve the fixed-point,fixed-timing,fixed-deep water sampling,can be a good solution to the traditional field water quality monitoring and sampling of large errors and random problems.At the same time it improves the quality and diversity of water sampling,it can reach the different needs of users.3.The field water quality monitoring and sampling system designed in this paper can collect and store the surrounding environment of sampled water quality,solving the deviation of the analysis results required from the Lab environment which is different from the actual environment.This can also help to improve the accuracy and reliability of water quality sampling results.4.On the basis of demand analysis,this paper studies the overall design of the field water quality monitoring and acquisition system,including the overall structural design and overall functional design.Then the overall model of the field water quality monitoring and sampling system is given,and the system is designed and implemented from hardware and software aspects.Based on the overall design scheme,the field water quality monitoring and sampling system is realized.5.The function of the system is analyzed and verified in this paper.The experimental results show that the field water quality monitoring and sampling system can achieve the monitoring and sampling functions of water quality,collect and store the parameters of the surrounding environment,solve the shortcomings of the traditional field water sampling system,complete the water samples of the fixed-point,fixed-timing,fixed-deep at the request of operators,and reach the diversity needs of water sampling from users.The processes of establishing and monitoring of the field water quality monitoring and sampling system is summarized and described at the end of the paper.Further work of this system is pointed out,and its broad application prospect is prospected.
