Research And Implementation Of The Hydrology Telemetric System Based On GPRS Network

The hydrology telemetric system collects and processes the hydrological information, In order to make exact forecast and dispatch. GPRS(General Packet Radio Service)is based on GSM(Global system for Mobile Communications) that offer wireless IP to the end and wide area of end to connect.This paper introduces a kind of new-type wireless automatic hydrology and monitors network. Weakness of the respect of gathering and transmitting that this network breaks through the network information of traditional automatic hydrology, combine the wireless mobile transition and Internet technology, use GPRS data terminal to realize the auto and wireless that hydrology monitors.Introducing every component of The hydrology telemetric system at first in the article, compare with the transmission means of traditional water level information afterwards, Introduces the relevant technology of GPRS system and network model and analyses to the communication agreement of GPRS, proposing utilizing GPRS wireless mobile network to carry on the transmission of the water level data, the result in practical application has been analyzed. Providing the objective and overall appraisal on the system in the end of the article, to improve and put forward the suggestion further.
