The Design Of Online Environment Monitoring System Based On GPRS

With the rapid development of China's economy, the blind development and construction in some areas have caused serious environmental damage and pollution. But the human survival and quality of life are closely related with the quality of the environment. Online environment monitoring is important work for department,include monitoring pollution,atmosphere,surface water,acid rain,yawa and adiation. Before monitoring measures were mostly used by manual , do not satisfy need of digital and net. Currently instrument of online environment monitoring are applied abroad in field of protecting environment, datas are great and meaning of real time monitoring are important. So environment data traffics were imperative under the situation.It is a fact that the monitoring locale is always far away for the city and has a bad transportation and telecommunication condition. According to the fact mentioned above,we have developed environment monitoring system based on the GPRS, in order to improve working efficiency. The system collection parameter of cod,bod,ph and so on. Data were send to gprs by gprs dtu, then were send to internet. Monitoring center of the upper computer compile programme of network communication in Delphi, data were saved in real time database of PC Auto, and were dynamic showed on interface. Monitoring center of the upper computer monitor,many locale equipments and carry out function of real time report forms,history report forms and alarm.Through debugging this system, the data receiving and dispatching were realized immediately, achieving the anticipated target and proving the feasibility of this system.
