Design And Application Of The GPRS Wireless Data Transmission Terminal

In recently years , mobile communication and mobile technology is developing with an amazing speed .With the expanding of its application ,mobile data service will play a more and more important role in all mobile communication service .Now the information in the world requires communicating between wire and wireless .The study object of this article is the GPRS wireless data transparent transmission terminal .The aimed application is the wireless data transmission in the industry field.The major works and contributors of this paper are as follows.Firstly, this paper expounds the background of advancing the study object .It points out the significance of the study .It also definitizes the contents of the study .Secondly ,The author expatiate the theory of the study including the theory of the GPRS. The paper gives the process that the terminal attaches to the GPRS net. The paper also analyses the protocols of the process .Thirdly, based on the theory, the paper proposes design requirements of the terminal. Then the paper analyses the scheme of realizing the terminal. Fourthly, this paper gives the design of the hardware and the flow chart of the software. Finally, this article builds up the communication platform of the power network voltage monitor system based on the GPRS wireless data transparent transmission terminal. Through this communication platform the author carried out a testing on the terminal .The paper also compares the GPRS communication platform with the traditional wire communication platform. The major contributors are that the author gave the design and test of the terminal and the terminal promoted the connection of wire and wireless.
