摘　　要：基于OpenWRT系统设计了一套WiFi探针实验装置,能捕捉其附近的数据包以解析出移动设备的MAC地址及其他有用数据,并将数据封装好发送到平台端测试验证。该实验装置的硬件基于MT7620A无线路由模块,软件部分通过在OpenWRT系统上解析802. 11帧结构实现WiFi探针功能。测试结果表明,探针能持续稳定地捕捉数据帧并解析出MAC地址上报,工作状态良好。该实验装置有机地将目前高校开设的嵌入式系统与计算机网络两门课程结合到一起,且充分拓展了实验室现有实验设备的功能,丰富了现有实验的种类。同时考虑到智能手机的WiFi MAC地址作为个人身份识别数据对于安防应用具有重要作用。Based on the OpenWRT system,a WiFi probe experiment device is designed,it can capture the data packets in the vicinity to parse the MAC address and other useful data of the mobile device,and package the data and send them to the platform for test verification. The hardware is based on the MT7620 A wireless routing module,and the software part implements the WiFi probe function by parsing the 802. 11 frame on the OpenWRT system. The test results show that the probe can continuously capture data frames and parse the MAC address report, and works well. The experimental device organically combines the two courses of embedded system and computer network opened currently in the universities,and fully expands the functions of the existing experimental equipment in the laboratories,and enriches the types of existing experiments. At the same time,considering the WiFi MAC address of the smartphone as the personal identification data plays an important role in the security application,and is beneficial to cultivate students.
