Design And Implementation Of The Mobile Terminal Integrated With 3G Commnunication Technology And Global Position System

The development and combination of computer technique and wireless communication makes a kind of new computing mode—mobile computing mode come true. At mobile computing environment, users use convenient computer getting network information through wireless communication interface, but not affected by actual physics position change. In the past 10 years, this kind of new computing developed rapidly, and in more and more fields, it takes function that can not be replaced. It can be predicted, mobile computing mode will become the important member in the future information ages, and take the profound influence in the ways of using information.The mobile terminal has the physical volume convenient to take, the powerful correspondence ability, favourable man-machine interface, abundant information handles function, mobile terminal has been an important branch in the field of mobile computing , is developing in the active period. This text combines the frame structure in"design and implementation of the mobile terminal integrated wiht 3G communication technology and GPS" of the plan item of province science technique in Heilongjiang. Using embedded system development method, we complete the designation of hardware and the software of the mobile terminal. I do the detailed analysis of the requirment for the mobile terminal, complete the designation of the architecture of the mobile terminal, carry on choosing a type to the hardware, succeed of transplant the embedded Linux to that terminal. In order to do the interaction more efficiently, the text puts forward a multimodal human-machine interaction model. I divide the application software into mold pieces, detailed design and carry out the data communication model and short message communication model and voice communication model. And the paper gets the needed GPS information from the serial port, then puts the data in the designed data structure for the application who needs them.The market hasn't appeared at present the product that integrates the communication and position techs. Therefor the development of this type's product has vaster market foreground. Comprehensive considered applied background and market need, we integrate PDA and 3G, the GPS technique in...
