Pda The Wiring Through The Study And Realization

With the wildly application of the embedded system, it has been developed into the 3G era. It's a hot focus how to make the common people log into the computer network easily and conveniently. The development of computer technology makes the communication system and information terminal more intelligent, especially the application of embedded system, which supports the technology for the development of the information termination.The main research content in the thesis is the design and realization of PDA Telecom Affair Transaction(PTAT). PTAT is a kind of telecom testing terminal used by telecom maintenance men; The appearance of PTAT fills up the blank of the market, which makes the communication between maintenance man and headquarters more convenient.PTAT realizes the call in PDA and brings forward the scheme of the SMS(short message service) which is similar with the mobile communication. It also transfers data by FSK and DTMF between PDA and servers, which fully makes use of telecom resources and saves the expenditure.In the basis of introducing the global architecture, the mostly discussed in the thesis is the embedded system architecture. With respect of its embedded environment, some of the key technologies, including embedded database system and embedded windows system.At the end of the essay, a summary of research on all aspects are given, along with hope of possible refine of further research.
