This article surveys the concept of Industry 4.0 (I4.0), which has become more and more pervasive in recent years thanks to the great effort that factories, researchers, and organizations are putting into its definition and development. We present the IoT as the key I4.0 technology since it enables faster and more efficient production and management processes, leveraging the flexibility of smart, ubiquitous, connected devices. In particular, we discuss the role of the I4.0 revolution in driving the diffusion of smart products and services, by focusing on ambient intelligence and context awareness in IoT and on the so-called DIKW hierarchy. Finally, to demonstrate the practical impact of this emerging framework, we show, as practical examples, three typical I4.0 applications in the smart factory, smart home, and smart health scenarios.

在物联网上为工业4.0应用开发上下文感知功能

本文概述了工业4.0（I4.0）的概念，近年来，由于工厂，研究人员和组织在其定义和开发方面付出的巨大努力，该概念已变得越来越普遍。我们将物联网作为关键的I4.0技术，因为它可以利用智能，无处不在的连接设备的灵活性，实现更快，更高效的生产和管理流程。尤其是，我们将重点关注物联网中的环境智能和上下文感知以及所谓的DIKW层次结构，来讨论I4.0革命在推动智能产品和服务的传播中的作用。最后，为了演示此新兴框架的实际影响，我们以示例为例，展示了智能工厂，智能家居和智能健康场景中的三种典型I4.0应用程序。
