无线局域网接入控制器在μClinux上实现
摘要
用无线电或者红外线代替传统的电缆，实现个人信息终端的智能化互连，组建个人化的办公或者家用信息网络是当今的热门技术。无线接入技术应用于家庭和办公室内，实现数据通信、语音通信、办公设备的互连以及Internet接入等功能。
针对短距离无线通信设备灵活移动性、低功耗、低辐射等特点，分析了当前的无线局域网接入技术和嵌入式系统的状况，通过比较分析，得出了蓝牙技术在无线网络接入控制器中应用的优越性。分析了蓝牙技术规范的体系结构、蓝牙协议、嵌入式Linux系统相关理论，通过μClinux系统移植到EV44B0Ⅱ开发板的来搭建了无线局域网接入控制的开发平台，实现了无线局域网接入控制器系统的的设计。
实验证明，移植好的μClinux操作系统和蓝牙协议栈可以比较稳定的工作在所设计的无线网络接入控制器上。移动设备通过蓝牙模块与无线网络接入控制器建立无线连接，实现小范围内无线设备相互通信及与Internet。
We use wireless or infrared instead of the tradition cable, achieveintelligentize of the personal information terminal and build the personal work orfamily information network .It is the fashionable technique now. Wireless accesstechnique is used in family and office; achieve data traffic, voice traffic, officialequipment, Internet access and so on.
Arming at the stone's throw wireless comnunications equipment fixibleremoval, low consumpion and low radialiazation etc characteristic, this paperanalyzes the domestic and international development of WLAN and embeddedsystem. Through comparation and analysis, it is more superiority to applyBluetooth technology in wareless access controller. Then introduces Bluetoothtechnologyspecification, Bluetooth protocol and recommands the correspondingembedded Linux. Above all, the developping platform aiming at the warelessaccess controller is builded by transplanting theμClinux system to the EV44B0developping board, Design of wareless access controller is realiazed.
Experiments show the system functions well. The wireless connection is setup by using Bluetooth module between wareless access controller and deminal,and impliments the function that the wareless equipments communicate with eachother in WLAN and Internet.
