面向物联网的智能传感器节点系统设计

Intelligent Sensor Node System for IoT

无线传感器网络(WSN)是物联网核心应用技术之一,由于WSN中节点多、数据量大,传感器将原始数据直接传至后台的传统方法会产生大量的能耗并增加后台处理压力。本文结合物联网WInternet的框架以及软硬件协同设计思想,提出了一种面向该物联网的系统设计与实现方法:将变频算法融入传感器节点高效采集数据,使智能传感器节点具有计算数据和制动外部设备的功能,并可实现就近计算,同时将Pipe协议嵌入其中,使得不同平台间无缝连接,以及节点设备对外提供服务。

Wireless sensor network （WSN） is one of the core techniques of loT. The traditional method will cost so much energy and increase the pressure of servers when the data is directly sent from sensor node to servers. A method of design and implement system for lot is proposed combining with the WInternet and hardware/software co-design idea. The frequency conversion algorithm integrates into the sensor nodes for data acquisition, which makes the sensor nodes have the functions of compute data and control outside devices, so that the closer computing is achieved. The different platforms can connect directly and the device can provide services through adding Pipe protocol.
