The Commonality Disease Incident Emergency Command System Embedded Handheld Information Collection Terminal

With the development of computer technology, the embedded system has been became the important apart of computer domanial. Embedded facility almost including all of electronic facility, such as PDA, IPTV, auto, elevator, security system etc.. In this 'after PC' epoch with digital information and network technology developing highly, embedded system has been widely gotten into lots of aspects , such as: science research , engineering design, military affairs technology, industry and commerce culture art, entertainment trade and our daily life. With the development and spreading of many kinds of embedded products, embedded technology has been become more and more related with our life. An embedded system can also be defined as a single purpose computer centered as application and based on computer science technology. The most difference between an embedded system and a general computer platform is that the former must support the cutting of hardware and software to meet the special requirements of the applying system for embedded system's volume, function, reliability, and cost and so on.This thesis mainly discusses the design and realization of the software and hardware of the embedded handheld information collection terminal, this kind of...
