Design and Implementation of Intelligent Access Control SystemBased on 51 Single Chip MicrocomputerAbstract:Today,as socio-economic and scientific leaps are made,essentially commercially availablee-commerce products are required to be small in size and easily portable.These standards have becomethe main future direction of electronic commercial products,so we will find that today's society isbecoming more and more convenient,handling things more and more quickly and efficiently.Safety isalso the most concerned problem of modem residents,can be opened with the key chain door lock is notsafe,but also very troublesome,so people are more and more demanding of door locks.What peoplereally want is the enthusiasm of an intelligent access control system that is both safe and secure andeasy to use.This project is designed to use the fingerprint module to identify the authority of fingerprintdetection and verification to make the operation of unlocking,but also can use the IC radio frequencycard to unlock,can read,add,delete and other operations through the radio frequency module IC cardintelligent access control system based on 51 single chip microcomputer,and through the liquid crystaldisplay output display,and then with relays,light-emitting diodes and electromagnetic locks analogunlock action.Keywords:safe and anti-theft,convenient,51 single chip microcomputer,loops and whorls on afinger,IC radio frequency cards.
