Research On The Collection And Transmission Of Target Information Based On ARM

With the vigorous development of ARM technology and wireless communicationtechnology in the contemporary society, the target information collection and transmission basedon ARM and wireless communication technology are more and more widely applied. Also, therequirements of target information collection and transmission become to be more and morerigorous. With the development of technology and maturation of applications, market demandfor portable or hand-positioning products is increasingly strong, the rapid development ofcomputers and ARM technology make target information collection and transmission to havegood market prospects in mobile devices.Based on the theory of the target information collection and transmission technology, animportant part of the system structure is discussed in detail after analysing the technology of theARM and the wireless transmission. The system of target information collection andtransmission based on ARM is designed and realized. The target information collection andreception of GPS and BDS is made. The display interface of mobile client terminal is designed.The program of the Android’s terminal is written with Java tool to implement the display of thetarget information. Wi-Fi wireless communication network is set up by D-Link wireless router, toget automatically assigned dynamic IP. A communication connection is established with the hostby logging on the communication network of S3C2440chip.The system is run, tested, and verified by the use of the measured targets data in threepositioning modes of BDS/GPS, BDS and GPS. It conducts the statistics and the contrast in thesatellite GDOPand the static posioning error for the three posioning modes. It contributes to areference for satellite positioning applications, especially for the promotion for wide applicationof the BDS, which is independently developed by China.
