Design Of The Hand-hold Equipment Of Missile Equipment Recycle System Based On ARM

The scope of the strategic missile falls is broad,so recycling search of equipment is difficult, while the GPS is stablest and maturest guidance localization technology in the non-war situation.The thesis introduced a project of embedded hand-hold search equipment based on the PXA270 microprocessor and Windows CE operating system.The device process the localization information of the hand-hold module itself and the localization information sent by the beaconing module, then obtains the relative position and carries on the fast search according to the change of the relative position. Because the search device is supported by the high performance microprocessor and the embedded operating system, the system that we developed has such characteristic: friendly operation interface, formidable performance, high extendibility and the support of auxiliary equipment interface is ample.According to the task, the thesis elaborated on the following four aspects:First, through the repeated investigation and study, provide a realizing framework based on"beaconing system + hand-hold system"and give out the system realizing scheme separately;Next, beginning with the feature of the embedded system, the thesis introduces the selection of the system hardware, the design of host module as well as the sub module, and then give a detailed analysis to the PXA270 microprocessor's characteristic;Once more, the thesis has carried on the design to the master-controller module's bootloader, and then has carried on the corresponding elaboration to the embedded operating system's selection, has focused on the discussion of the Windows CE's reasonable cutting out and transplant as well, in order to achieve original intention; Finally, the thesis introduces software development method with Windows CE operating system, and then give a detailed application programming to GPS localization, wireless data receiving and sending as well as embedded GIS .The combination of embedded technology,GPS technology and wireless transceiver technology brings out the best of the latter's instantaneity, the flexibility and the embedded technology's miniaturization, multifunction and high efficiency. Combination of Windows CE platform will enable the design of hand-hold devices more flexible, thereby effectively cut down costs.
