无线门禁系统的研究与设计

Research and Design of Wireless Access Control System

该文通过研究,用TMS320F28027的DSP作为主控芯片,设计了一款无线门禁系统,主要用于,用于控制门限控制。门禁系统由主机和从机两部分组成。主机是每次通信的发起者,负责通信链路的建立与终止,在通信过程中占据主导地位。从机被动等待连接,配合主机完成通信过程。设计主要包括门禁主控设备、无线射频模块、语音模块、刷卡模块、电控锁等模块。该设计方便快捷、采集信息准确,具有良好的应用价值。

In this paper, a wireless access control system is designed by using TMS 320 f 28027 DSP as the main control chip, which is mainly used to control the threshold control. Access control system consists of two parts： master and slave. The host is the initiator of each communication, responsible for the establishment and termination of the communication link, and occupies a domi- nant position in the communication process. The slave waits passively for a connection to complete the communication process with the host. The design mainly includes access control equipment, radio frequency module, voice module, card module, electric con- trol lock and other modules. The design is convenient and fast, and the collected information is accurate, it has good application val- ue
