| Involves the war industry and the security technology production research anddevelopment enterprise regarding some is also the security enterprise, not only needcare that staff’s attendance rate, needs to guarantee arrives at the operating post only tobe able every day to be the interior work personnel. Therefore the security enterprise’schecking attendance management system should better use the fingerprint to distinguishthis way, guarantees its uniqueness. The dissertation uses the embedded processorARM9processing the fingerprint data which gathers to the fingerprint gathering moduleto carry on the pattern recognition, the extraction characteristic, writes down thefingerprint database, the characteristic match, the demonstration result, through serialport RS232upload data to computer terminal.The main contents of the dissertation are as follows:1. Has designed the overall scheme in view of the security enterprise checkingattendance management system’s characteristic.2. In order to meet the fingerprint recognition checking attendance systematicneeds, through the fingerprint recognition way and the algorithm, had determined thissystem uses the recognition technical design and realizes the scheme.3. Proposed for guarantee enterprise daily operation highly effective at the sametime, guaranteed the recognition reliable should use fingerprint recognition software andhardware implementation plan.4. To realize the system plan need satisfied, realizes the method through theanalysis common fingerprint recognition checking attendance system, had determinedrealizes system’s hardware platform. Completed the fingerprint recognition algorithm,the fingerprint match, link’s and so on result upload hardware has realized, furthercompleted the overall system to realize the work.5. Through in the hardware platform to the system design plan’s performance indextest, indicated proposed the plan and realized the result to achieve the system designrequest target. |
