Design And Implementation Of Monitoringsystem For Key Lake Water Quality Indictors

The protection of water resources,water pollution prevention and control is the sacred and the responsibility of the whole human beings.With the continuous prosperity of economy,water pollution is becoming more and more serious.The use of artificial methods to monitor and control the water pollution is more and more difficult.Therefore,it is necessary to establish the water quality monitoring system based on information technology.This thesis with water quality in Lake,key indicators of monitoring as the research content and scheme of water quality monitoring of detailed design and implementation of the use of computer systems.First of all,the system analysis of the various data lake water quality analysis,establish the index database module.From the physical properties,non metal inorganic compounds,metal inorganic,metal minerals,such as 17 data table design and implementation,this paper establishes the more perfect Lake Placid water quality indicators database.Secondly,the system of water quality analysis is designed.Take the data acquisition,data analysis,data evaluation function partition,on water quality analysis system was designed,according to the different function modules of the system,the function requirements were analyzed,based on completed the detailed design of the system,the timing diagram analysis,analysis of the system implementation steps.Then,the Delphi and web programming method,the Lake Placid water quality analysis of the modules of the system,through the establishment of the web interface of data access realization method,using XML data mapping and implementation of the general data acquisition model,gives the system analysis and supervision control to achieve the core method.In this paper,the water quality is evaluated by the analytic hierarchy process.Using physical,chemical,metal,nonmetal,water biological five key indicators of the method,the water quality assessment,through the establishment of assessment model,the initial realization of the water quality assessment.From the point of view of practical application of the system.The system has initially realized the Lake Placid water quality analysis and monitoring function,to realize the automatic water quality monitoring analysis,has a certain practical value.
