摘要
物联网技术是通过多通道通信技术的信息传感设备进行信息采集,同时采用网络终端来按约定的协议实现人与人、人与物、物与物的全面互联的一种网络技术。其主要特征是通过射频识别、传感器等方式获取物理世界的各种信息,然后结合互联网、移动通信网等网络技术进行信息的传送与交互,最后采用智能计算技术对信息进行分析处理,从而提高对物质世界的感知能力,实现智能化的决策和控制。为此,文中介绍了物联网技术的节点架构和基于无线传感器网络技术的数据查询,最后对高职学院的物联网实验室建设工作进行了分析和探索。
The IOT technology is a network technology that collects information in physical world using sensors based on the multi- channel communication technology and can achieve full interconnection between person and person, person and matter by network terminals with the agreed protocols. The main characters of this technology are that it collects information in the physical world through RFID and sensors firstly, and then transfers and exchanges information with Internet and mobile communication networks, finally realizes intelligent decision and control after analyzing and processing the information using the intelligent computing technology, and sequentially improves the perceptivity of physical world and achieves intelligent decision and control. This article also describes the node architecture of the lOT technology and the data inquiries based on wireless sensor network technology. The lOT laboratory building is analyzed and explored lastly.
