摘要
为了解决无专用通信基础设施或者通信基站失效地区内的局域通讯问题,提出一种基于msstatePAN协议栈的无线自组织网络的通信系统的设计思路。该协议栈建立于IEEE802.15.4通信标准的基础上,并且针对使用场景参照ZigBee技术做了相应的修改与优化。文中设计了一款自组织网络模块,该模块以STM32F103CBT6为硬件平台并可通过USB与手机相连进行数据交互,详细讨论了基于A7190芯片的模块的硬件设计方法及组网设计中的通讯数据收发的软件设计方法,最后给出了该设计方案在室内环境下组网实例及室外环境下的通讯质量测试结果。实验结果证明该系统具有稳定性,可靠性,可重复性,可以用于实现手机处于无LTE信号状态下的局域通讯。
To solve the problem occurred in local area communications when dedicated communication infrastructure absent or communication base station fail, this paper proposed a design for communication system adopted local wireless self-organizing network , which is based on msstatePAN protocol stack. The protocol stack based on IEEE802.15.4 standard and made appropriate change and optimization for scenes to be used reference to ZigBee technology. This paper designed a self-organizing network module, the module use STM32F103CBT6 MCU as hardware platform and connected via USB port for data ex- change with mobile phones, The hardware design based on A7190 RF chip and software design to send and receive data are also discussed in detail. Indoor networking example and outdoor communicate quality test results are present in the last. Experimental results show that the system has stability, reliability, repeatability, can be used to implement local communication when phone in no LTE signal state.
