The Study And Design Of Intelligent Building Unit Access Control System

Peoples requirement of "home", is becoming higher and higher in modern life，from living environment and supporting facilities to building access control controllerunit facilities in communities. Realization of safe and efficient management ofintelligent building unit of the access control system not only is consistent wishes ofthe residents, but also is unremitting power of promoting intelligent communityprogress.Gate access control system’s development in our country has experiencedfrom traditional key lock to keys and swipe CARDS together to magnetic card.Nowaccess control system also equipped with a parking card and intercom system whichcan be used to simply and safely confirm the identity of the visitors for residents.This design including hardware circuit design and software design is mainlybased on fingerprint identification module as the core of the intelligent building unitaccess control system. That is to say, The design includes building unit entrance guardcontroller design and community management host of database design.Building unitof the access control controller design includes the connection of fingerprintidentification module M04A and C8051F040single chip hardware,the establishmentof the communication, LCD display design, store design, the design of the powersupply and building intercom system design.Data management through the homes,building a single controller, community management center of different authorizationmanagement respectively and it also requires fingerprint information collection andinput, alignment, etc.Because building unit access control controller design is controlled byC8051F040in LAN. Fingerprint data processing speed is very fast. The connectedof host community management host with all building unit access control controllerand the sending and receiving data through the CAN bus technology, using the bus thequickness of data transmission and real time.Intelligent building unit access control system has realized to the determinationof a resident identity, improve the level of the community of intelligent management,also convenient for residents to enter the cell door and guarantee the safety ofresidents.
