The Research And Realization Of The Mobile Position Information Switch Terminal Based On The GPS And GPRS

As the development of the times, the embedded application technology is spanning to various fields with startling speed. It is present everywhere, from modern communication to industry control, so much as national defence and security. The mobile position information switch terminal is an integrative system conbining global position system with mobile communication technique. It can automatically trace and locate the mobile object, and can be used to trace kinds of terminals.The design course of the embedded system is introduced detailly from the aspects of hardware and software in this thesis. The design adopt the top to bottom disgn method, that is to say the main frames of the whole system shoud be constructed first, then every frame should be realize in detail, and at last do the coding, debug and testing word.The embedded system's origin and development experience, the characteristic of the GPRS wireless communication technology are also introduced in this thesis. And a solution is given about how to design a mobile position information switch terminal combined with the GPS technology. The hardware design and the software realization are also given in this thesis. The mobie terminal's hardware is composed of the GPRS chip, the GPS chip, the embedded micro process, LCD and the keyboard. The softeware includes the receiving and the processing of the GPS data, the receiving and the sending of the GPRS data, the human-computer interaction.As the deep research continues and the terminal's fuction becomes more and more flawless, the generalization and application of the terminal will improve the benefit of the enterprise that uses it and will enhance the competition of these enterprises.
