Research And Implement Of RFID Reader Handheld And Based On ARM

Modern science and technology are advancing rapidly and greatly promote theautomatic identification technology—bar codes, optical character recognition, magnetic(card), IC card, speech recognition, visual recognition, RFID and so on; Of all, RFID isthe most advanced, which is a non-contact identification technology; Meanwhile, withthe progress of a technical-the embedded technology, compact bodies, superiorperformance, low price, fi'iendly operational and hand-held automatic data reading andwriting device is developing rapidly. Specifically, one good hand-held RFID Reader iscapable to work on the spot and provides staffwith on-site materials informationcollected automatically; With the application of embedded operating systems andnetwork technology, reader is able not to only collect data automatically, but also toanalyze data for management decisions. In this field, operating systems, chips, businterface technology to become Reader kernel and embedded system becomes technicalrepresentatives.With the use of embedded operating system (such as Linux, wince.net),programmer feels no difference on the development of application software betweenembedded systems and general pc machine (through cross-development environment,compiling and linking are on pc, but final code is aim at goal machine). However, forthose applications developers, too often they are quite familiar with some particularsoftware development about some special industry but not unfamiliar with hardware(Embedded Processor architecture etc). Therefore, building a stable, perfect datainterface, RFID-API hand-held equipment is today's hottest technologies. The project isbased on the popular ARM processor and wince.net operating system, and designs anddevelops handheld RFID reader for use of RFID application development. Accordingto requirement of handheld device, project designs hardward system for reader and develops RFID-API for RFID application program;Under wince.net, through platform builder customs operating system of reader andcompletes the design of embedded operating system. At last, the whole system wastested to be sure of correction of the system.
