传统的门禁系统大多采用有线通信技术,底层各个门的控制器与上层通信要通过有线连接。这样就造成了工程量大、施工难度大、设备之间物理连接复杂以及网络改造施工困难。因此对现有的门禁系统现状进行了改进,利用ZigBee无线通信技术,提出了一套无线门禁系统解决方案。其中硬件部分利用AVR mega16单片机设计了能够实现刷卡开门、无线传输卡号信息以及上位机显示开门信息功能的智能无线门禁系统平台。同时利用LabVIEW软件搭建上位机,设计了门禁系统登录和操作界面。最后在功能上实现了刷卡开门,并将开门卡号通过无线传输到上位机进行显示,达到预期设计的要求。同时设计具有实用性,可以运用到现代化小区的楼宇系统之中。
Most of the traditional access control system uses wired communication technology, the bottom of the door controller and the upper communication through the wired connection. This resulted in a large amount of construction, construction difficulty, complex physical connection between the devices and network reconstruction difficulties. Therefore, the status quo of the existing access control system has been improved. By using the ZigBee wireless communication technology, a wireless access control system solution has been proposed. The hardware part of the use of AVR mega16 SCM designed to achieve the credit card open the door, wireless transmission card number information as well as the host computer to open the door information smart wireless access control system platform. At the same time, using LabVIEW software to build PC, designed access control system login and operation interface. Finally, the function of the card to open the door, and open the card number wireless transmission to the host computer to display, to achieve the desired design requirements. At the same time design is practical, can be applied to the building of modern district system.
