The gate entiance contiol system to replace open a door witli a key way to mducnon card. A user with a card can open the lock on the door lock, the opening can also have a certain time limit. If the caid is lost do not have to change the locks, the cancellation of its control fiom the host. The gate entrance contiol system thiougli contioL equipment management and lecoids of the admittance of entrance to whom, when and where to detailed tiacking, to aclueve the centei on the entiaiice 24 hours control, monitormg and management. Tins system uses 89C51 Series MCU STC89C52 as the contiol core, the use of contactless IC card infonnation of high fiequency Mifare IC card module to read the users hands, ratio of IC are checkmg data lecogmtion after successful and storage system, if thexe is evidence that the IC caid IC caid IC card database legal, chip by controlling the relay coutiol electioiuc lock opening and closing. At the same time the system uses the 4X4 matrix keyboard as input, LCD1602 liquid crystal display as human-computer intera
