摘要 设计ZigBee网络侦听系统的框架结构,从功能上划分,本系统包括两个部分:侦听节点部分和侦听软件部分。侦听节点主要包括串口配置模块、命令交互模块、数据收发模块和数据上传模块。这些模块主要实现了串口初始化、信道设置、网络中数据包的获取和把获取的数据包传到上位机。侦听软件主要实现了对下位机的控制和对获取数据的处理,以及分析结果的显示。系统利用CC2430强大的DMA功能把数据从RFD寄存器转存到串口发送缓冲区。最后调用串口收发函数将数据上传到上位机或者将上位机发送过来的数据传递到CC2430,同时详细介绍了各功能模块的实现。在CC2430芯片上完成了侦听节点程序的设计,分别阐述侦听程序、侦听软件、数据包上传和任务调度的设计方法。搭建无线传感器侦听系统,对当前ZigBee网络进行侦听。通过大量的测试实验对软件实现的功能进行测试和评估。 The frame structure of ZigBee network interception system is designed in this paper. The system consists of two parts,interception node and software. The interception node includes a serial port configuration module,command interaction module,data transceiver module and data upload module,etc.,which mainly realizes serial port initialization and channel setting,and obtains the packets in the network and sends them to the upper machine. The software is used to control the machine,processes the data obtained and displays the analysis results. It sends data from RFD registers to a serial port to send buffer by DMA of CC2430. A serial port is used to send and receive function,uploading data to PC or transferring the data of the PC to CC2430,and the realization of each function module are introduced in detail. On chip CC2430,the interception node program is designed,the interception program,the interception software, data packet uploading and design method of task scheduling are described respectively. A wireless sensor interception system is set up to intercept the current ZigBee network. The experiments are performed to test and evaluate the function of the software implementation.
