基于IEEE 802.15.4的无线USB适配器设计与实现

在无线传感器监测网络中,通常需要一个网络协调器将各终端节点采集的数据上传给监控中心,但是在有些场合用网络协调器组网很不方便。为此,本文介绍了利用USB接口技术优势结合IEEE802.15.4标准协议特点开发的无线USB适配器,详细阐述了该设备无线收发器模块、USB与串口数据转换模块等部分软、硬件设计原理,并通过组网进行了实际的测试。该设备的设计解决了现场监测环境中一系列组网复杂、开发成本过高等实际问题。

Design and implementation of wireless USB adapter based on IEEE 802.15.4

In wireless sensor monitor network, usually needs a network coordinator take the terminal node gathering data upload to monitoring center, but in some situations not to be very convenient. Therefore, this paper describes the use of USB interface technology combination of IEEE 802. 15.4 standard protocol features to development a wireless USB adapter, described in detail the wireless communication module, USB and serial converter module and some other hardware and software design principles, and carried on the actual test through the network. This device＇s design solved a series of actual problem that the networks to be complex,development cost higher and so on in the scene monitor environment.
