Research And Realize Of Real-Time Online Environmental Monitoring Based On The GPRS

In recent years,with the rapid econimic growth of our country, the emissions of industrial pollution are more and more,so the pressure of the Natural Environment are more and more,this problem has already been more focused on by society. Therefore , establish a full-featured environment monitor system has become an important task of monitor department even all of the society.There are many characteristics of the area of environment monitoring,such as dispersed, complicated geographical conditions,nobody guard and so on.Now many systems of monitoring get the data by manpower,that is waste time and inefficient,others systems of monitoring get the data through the wire communication,that has many bothers in collocating wire and can't translate remotely.So it is necessary to find a method to transfer data.At the same time,the work of environment monitoring is often necessary transferring the data in different region.But now there is not an effectual flat for transferring the information between the regions of environment monitoring. Traditional communication have some weak points, such as:cost mostly in construction,high operating costs,difficult to maintain and expand and so on. Now, the GPRS network is a kind of high-speed data transmission, covering a wide range,real-time online and stable ways of communication.Therefore, this system uses GPRS communication in the monitoring system it is a kind of economic, reliable, ideal design plan. this paper will detail narrative from these part.This paper research the environment monitoring system based on GPRS from two parts: First,data collection part,this part inlcude the design of data transmission between data collection device and data collector, between data collector and GPRS DTU, and GPRS DTU' dial-up config. The main features include: this part will transmission the data what from data collection device to GPRS DTU after analytical and processing by the data collector, then transmission the data to the data center server by wireless means. adjust the data collection mode base on the control order which from the center-side, config the equipment parameters and data parameters and so on .Second,data management part,this part main includes establishing a transfer data platform ,in order to make data from different enterprises's monitoring station to the main station for uniform management. Analysis and processing the data which from GPRS DTU,There are specific:summary, classify, analysis, storage, release, etc.In addition,there are some management about system administrators,data collection device and other auxiliary,these function will help the system administrator image,effective,accurate analysis the environmental problems in monitoring regions.
