智能门禁系统设计(论文11000字)
摘要:在日常工作和生活中,安全保护和身份识别需求日益提高,不仅需要各种身份识别和密码验证,还需要各种防盗系统和安保系统等等。随着现代科技发展日新月异,传统的防盗系统和安保系统存在着各种各样的缺陷,安全风险与日俱增,面临着巨大的考验,传统的身份识别和密码验证技术有待突破。因而,利用生物特征识别进行身份识别和密码验证的技术应运而生。生物特征识别技术通过生物技术和信息化技术利用生物固有的生理特征(DNA、人脸、虹膜、声音、指纹等)来进行身份识别鉴定。指纹特征作为生物特征之一,具有唯一性、终生不变性、验证方便快捷等特点,十分适合身份识别和密码验证的应用。本设计使用51单片机STC89C52作为主控芯片,使用液晶显示屏1602作为显示器,采用串口通信的方式与指纹识别模块FM-180连接,外围硬件电路包括晶振模块、稳压模块、电源端子、按键模块,通过软硬件的结合,最终实现一个拥有对指纹输入、查询、清除功能的指纹识别系统。

Design of Intelligent Access Control System
Abstract:In daily work and life, the demand for security protection and identity recognition is increasing day by day. It requires not only all kinds of identification and password verification, but also various anti-theft systems and security systems. With the rapid development of modern science and technology, traditional anti-theft system and security system have various defects. Security risks are increasing day by day. They are facing great challenges. Traditional identification and password authentication technologies need to be broken through. Therefore, the technology of identity recognition and password verification based on biometric recognition emerges as the times require. Biometric identification technology uses biological intrinsic physiological characteristics (DNA, face, iris, voice, fingerprint, etc.) to carry out identification through biotechnology and information technology. As one of the biological features, fingerprint features are unique, lifelong invariant, convenient and fast to verify. They are very suitable for the application of identity recognition and password verification. This design uses 51 single chip STC89C52 as the main control chip, LCD 1602 as the display, and uses serial communication mode to connect with fingerprint identification module FM-180. [20]The peripheral hardware circuit includes crystal oscillator module, voltage stabilization module, power terminal and key module. Through the combination of software and hardware, a fingerprint identification with fingerprint input, query and deletion functions is finally realized. System.
Keywords:Fingerprint Identification System, Fingerprint Identification Module FM-180, SCM STC89C52, LCD 1602
