Studies On Mobile Water Quality Monitoring System For Sudden Water Pollution

In recent years,the surface water pollution caused by chemicals and heavy metals shot up,which is a serious threat to people's lives and property safety.When the pollution accident occurs,the most important thing is to timely and accurately trace the source of the pollutants,in order to get the source information and deal with the pollution scientifically.But in practice,it is difficult to obtain the information of pollution sources in the early stage of the pollution event.Based on the analysis of the research status and advanced technology of mobile water quality monitoring system both at home and abroad,this thesis studies the traceability algorithm suitable for mobile water quality monitoring platform under two-dimensional waters,and designs a small mobile water quality monitoring system.The main research work is as follows:The three parameters,the inertia weighting factor,acceleration constant and scaling factor,which belongs to particle swarm differential evolution hybrid optimization algorithm(PSO-DE)are improved,and then the improved algorithm is applied to the traceability calculation of two-dimensional water pollutants.The simulation results show that the algorithm can complete the traceability of fixed point source pollutants in two-dimensional waters with high precision.Completed the overall design of the small mobile water quality monitoring system.The system is composed of mobile water quality monitoring platform,monitoring center and mobile terminal.Can achieve rapid detection of water quality,high precision sampling.Automatic navigation uses 3G communication and GPS positioning.The software and hardware of the mobile water quality monitoring platform are developed,including the hardware design of mobile water quality monitoring platform,the development of Linux driver and application program.The software of mobile terminal and monitoring center server are also developed.
