摘要
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
