基于STM32的智能門禁系統的設計隨著科學技術的不斷提高，人們的生活水平不斷提升，智能建筑將會在未來的 城市建設中發揮重要的作用。門禁系統是智能建筑領域非常亜要的組成部分，不僅 能夠控制人員進出權限，還能夠對這些人員的出入情況進行實時監控與記錄:，是智 能建筑必不可少的安全防范設施。射頻識別門禁系統存在認證介質容易丟失、損壞, 指紋識別門禁系統容易受到環境的影響。該設計針對目前的門禁系統研究的現狀和 發展的狀況做了簡要分析，結合對RF1D技術和指紋識別技術的研究，提出了一種 基于STM32的智能門禁系統設計方案，采用指紋識別技術和射頻識別技術兩種識別 方式進行身份蛤證，完成門禁系統的多重驗證方式。避免了單一門禁系統存在的安 全隱患，提高了系統的穩定性和安全性。具體設計方案如下：
硬件方面采用STM32作為控制器，結合電源、射頻識別、指紋識別、繼電器 等模塊構建門禁系統終端的總體硬件架構。
軟件方面結合硬件架構，采用模塊化沒計思路，設計開發主程序設計模塊，指 紋識別門禁模塊，射頻識別門禁模塊。上位機采用C#語言進行設計開發，實現門 禁管理系統的設計。
在面對“互聯網+”、物聯網、移動智能化的挑戰之下，門禁技術不斷的創新 ，門禁系統進入了前所未有的轉型期。單…驗證方式的門禁系統將被取代,智能門 禁系統將成為門禁行業未來發展的趨勢。

Abstract
With the continuous improvement of science and technology, and the people's living standard intelligent building will play an important role In the future of urban construction. Door-control system is a essential key componenl of the field of intelligent building. Il can not only control the access authority of personnel but also monitor and record the access of these personnel in real time, which is an indispensable security and prevention facility of intelligent building. The identification medium of Radio frequency identification access control system is easily lost and damaged, and the imgerprint identificalion access control system is easily affected by the environment. This design makes a brief analysis of the current research status and development of the access control system and proposes a design scheme of intelligent access control system based on STM32 by combining with the RFID technology and fingerprint identification technology research. This design scheme adopts fingerprint identification technology and radio frequency identification technology to verify the identity, and completes the multiple verification of the access control system which can avoid the hidden danger of single access control system and improve the stability and security of the system The specific design scheme is as follows:...
