摘要
在无线传感网络中,信号的类型多种多样并相互混合,为无线传感网络的信号分离工作带来了挑战。因此,设计无线传感网络信号分离提纯模块,对无线传感器网络节点、信号分离平台和信号提纯平台进行设计。无线传感器网络节点利用6700K处理器进行无线传感网络信号的采集和管理。信号分离平台构建运动坐标系和BP神经网络模型,将无线传感网络信号准确分离并传输到信号提纯平台。信号提纯平台将信号中多余参数和编码除去,以缩减模块能耗、提高模块准确度。模块实现部分给出了模块的功能图,以及信号提纯平台基站中BOA服务器的工作流程图。经实验证明,所构建的模块拥有准确度高、能耗小的特点。
In wireless sensor networks,the type of signal is various and mixed each other,which brings about a challenge for signal separation of the wireless sensor network(WSN). Therefore,the WSN signal separation purification module,WSN node,signals separation platform and purification platform were designed. The 6700K processor is used for the WSN node to col?lect and manage the WSN signals. A motion coordinate system and BP neural network model were established for the signal sepa?ration platform to separate the wireless sensor network signals accurately and transmit it to the signal purification platform. The signal purification platform gets rid of excess signal parameters and codes to reduce the module energy consumption and improve module accuracy. A module function diagram and the work flow chart of BOA server in signal purification platform base station are given in the module implementation paragraph. The experiment result proves that the module has the characteristics of high accuracy,low energy consumption.
