| Various kinds of recognition systems of identity based on human body's physiological characteristics, for instance: fingerprint, palm, sound, retina, pupil and surface line, etc, because it cann't be forged has already become a kind of convenient and safe identity authentication technology. At present, from the theoretical research the fingerprint recognition is superior to the recognition tecnology of other living beings. And all kinds of fingerprint product show in market.This article design and realize fingerprint Door-lock system network based on ARM. This system use of modern fingerprint capture chip. Because it operation safe, easy expend, netwoek use and low cost, it can be used all kinds of identity recogniseing.To guarantee the operation that the whole system is high efficient, orderly, steady. This article adopted IC/OS-II operating system to management and attemper various kinds of tasks, which can effectively overcome the weakness of the individual procedure operated and very easy to upgrade and expand the new function to the system. And complete transplanting HC/OS-II to ARM.To realize remotely control and lower costs, this text makeuse of Ethernet structure to realize remotely transmit of data.Then complete cuicrit design and success debugging. Adopting software simulate to complete bus data reading&writing, which solve there isn't data bus and address bus problem. And descible Ethernet protocol and complete drevice program.Compareing with single fingerprint Door-lock system, utilizing this scheme, we have three merits: 1, it can decrease system cost, we do not need other special wiring where there is exit network. 2, using operating systems to management and attemper various kinds of tasks can improve system steady and safe.3, because of fingerprint data memory and recognising be complete by PC, which can improve system recogniseing speed and veracity, then system capability will be increased,...
