摘要：无线通信技术是近年来广泛应用于现代服务业、生产制造业等各个行业的一门新技术。本设计在此基础之上，结合了单片机C8051F320，EEPROM W25X80芯片，LCD显示以及NRF24L01无线传输的知识，设计了一种无线发射的门禁系统。它的特点是车辆在将要进入小区内的一定距离范围内（大约4米范围内）通过按动车内车载终端的按钮触发终端无线发送请求信号，本设计中是利用电池对标签卡进行供电并无线发射，通过门禁控制器验证信号，使得车辆在一定距离内与小区门禁系统进行无线通信，从而使得已认证的车辆可以自动打开小区的大门。

Abstract：Wireless communication technology in recent years is widely used in modern service industry, manufacturing, and other industry a new technology. This design based on this, the combination of the single chip computer C8051F320 block, EEPROM W25X80 chip, LCD display, and NRF24L01 wireless transmission of knowledge, design a kind of wireless transmitting the entrance guard system. It is characteristic of the vehicles in the community in entering within a certain distance (about 4 m wide) through the press the button car car terminal trigger terminal of the wireless delivery request signal, the design is to use the battery to label on the power supply and wireless card launch, through the entrance guard controller test signal, make vehicles in within a certain distance and village entrance guard system for wireless communication, thus make the already authentication of the vehicles can automatically open the gate.
