物联网将智能感知技术、异构网络传输技术、海量信息处理技术等多种前沿技术相融合,在智慧物流、工业控制、智能交通、智能电网、医疗卫生、智能农业和节能环保等领域发挥着巨大的作用,被称为继计算机、互联网之后,引领世界信息产业发展的第三次浪潮。学术界一般将物联网系统结构抽象成三个层次:感知层、网络层和应用层。感知层是物联网系统的神经 The IoT integrates various cutting-edge technologies such as intelligent sensing technology, heterogeneous network transmission technology, and mass information processing technology, and plays an important role in such fields as smart logistics, industrial control, intelligent transportation, smart grid, healthcare, smart agriculture and energy conservation and environmental protection Huge role, known as the computer, after the Internet, leading the development of the world’s third wave of information industry. Academia generally abstract the structure of IoT system into three levels: perception layer, network layer and application layer. The perception layer is the nerve of the Internet of Things system
