基于二维码的门禁系统设计

Design of Access Control System Based on Two-dimensional Codes

设计了采用二维码作为门禁钥匙的门禁系统,具有特定区域使用权限的用户可以通过手机APP生成包含用户信息且有时效性的二维码。通过TX200设备完成扫描,用户的基本信息会在LCD12864上显示。如果数据匹配则会启动电机开启门禁,并根据用户数据确定是否需要提前开启车位控制器,过程中配备语音模块进行提示。用户还可以扫描二维码,通过步进电机模拟实现要达到的楼层。系统克服了一些传统门禁的缺点,实现了无卡化操作,更加方便快捷,安全性能高。

The access control system uses a two-dimensional code as the access control key.The user who has authority in the area can generate a two-dimensional code of timeliness and user information through a mo-bile phone APP.The user's basic information will be displayed on the LCD12864 by scanning the TX200 device.According to the user's data to determine whether you need to open the parking space controller in advance,ifthe data can be matched,the access control will be started by the motor,which is prompted by the voicemodule during the process.The user can also scan the two-dimensional code and simulate the floor to bereached through a stepper motor simulation.The system overcomed some of the shortcomings of traditionalaccess control,and conducted the operation without card,which was more convenient and faster,and hadhigher safety performance.
