Research And Design Of Access Control System Based On Database Technology

The concept of access control system is an essential ingredient of every community was introduced in the 1980 s, having gone through technological change, which has appeared password access control, contactless IC card,contactless IC card and biometric access control system, the development of these access control has been a continuous process, its application areas range also has expanded from a military to a civilian range.Supported by Science and Technology Plan Project in Chang Chun:Key Tech nology Research and Application Platform of Intelligent Buildings Information I ntegration Based on Internet of Things, this paper has done deep research to solv e the existing problems of the access control systems in the current domestic mar ket, such as rare core technology, poor user experience, and less creativity.The fingerprint identification and database together with CAN bus technology in this paper that design a more humanity and comprehensive yet lower power consumption fingerprint access control system. This system uses microcontroller as its core control chip, and fingerprint recognition module of low-power operation for its fingerprint recognition work; up to 128 lines of calling intercom are controlled by the expansion I / O and analog switch control;accessing the server to upload information by using CAN bus as their communications network; recording people’s identity information through database access technology comprehensively; using Delphi programming language to design all functions of human capabilities.The design focuses on the innovation of usage methods, basing on the core technology mastering communication access control, we work for users a more comfortable services of them as much as possible. To ensure the basic functions of the community Access control system, we design various utility functions that have capability to improve the experience of access control system.
