Design Of Integration Fingerprint Lock

Along with the development of society economy and technology, people put forward the higher requirement to the safety, especially in bank, customhouse, public security and small area of top grade etc the domains, the status that who is a personnel looks very important quickly. The research content of this subject is to design the integration fingerprint lock by using only nature and the invariance of the human body fingerprint as " key ".Papers on fingerprint image processing feature extraction and matching techniques, the feature extraction process are described. Based on the matching technology is given the dynamic characteristics of a flexible point matching algorithm. Lock for the technical indicators of integration requirements, thesis discusses the design, detailed design of the lock’s power supply, fingerprint input, MCU control, keyboard scanning, liquid crystal display modules. And through software design, the realization of the input fingerprint lock, password, clock settings, view the unlock record, the user fingerprint collection, than the right, delete functions. Finally, lock the prototype was tested, test results show that the products meet the requirements of technical indicators.
