Design And Realization Of Intelligent Water Quality Monitoring And Response Control System

Water resources,as an important part of the natural environment of the world,is the basis for the survival and development of nature.The sustainable use of water resources is of great significance to the development of social and economic sustainability.However,with the development of modern economy,the pollution of water resources is becoming more and more serious,which leading to the gradual reduction of available water resources.Therefore,the real-time monitoring of water quality and the development of automation improvement water quality improvement system can effectively improve the water quality.The long-term real-time detection of river water quality is of great significance.In this paper,a set of fully automated intelligent water quality monitoring system is designed for the real-time monitoring of water quality and the requirement of improving the water quality.The system can effectively realize the long-term numerical parameters extraction and can adjust the water quality parameters automatically to improve the water quality situation.The hardware of the system mainly includes the part of water quality parameter acquisition,the part of water quality parameter improvement,the part of acquisition data conversio,PC control and PC display.Host computer and the lower computer communication is mainly communicatee by RS485,the display and control software of the host computer is used VS2008.The main work of this design: the overall design of the system and the parameters of the target,the hardware of the system,the underlying system driver software,the system display interface software design and overall debugging and assembly.The system tested the basic parameters including water quality: temperature,pH and dissolved oxygen four parameter,and as a result of heating rods,pH adjustment substances and aerator to adjust the relevant parameters,the collected data through the host computer curve form of visual display and were stored in the database,the saved data can provide a basis for water quality analysis.the design of the parameters is in line with the relevant parameters of the sensor,and configures the conditioning circuit,the collected data through the core controller STM32F107 processing analysis,the processed data was sent to the host computer display by the interface,and made the appropriate adjustment control.The host computer adopts the VS2008 integrated development environment to compose the display interface,realize the grapHical display of the data,and combine the database technology to realize the historical data analysis and inquiry function.In the actual test of the system,the data of the collected data and the calibration data are kept within the allowable range to ensure that the water quality parameters can be obtained in real time for a long time.The reliability of the communication mode is high,and the goal of the system design is achieved.Aquaculture has important engineering applications.
