摘要

技术进步正在使工业格局发生重大变化。运输、医疗和航空电子等传统部门正在见证供应链和内容的根本变化,其中物理世界和计算世界之间的相互作用变得越来越紧密。网络物理系统、系统的系统、物联网、工业4.0、群系统和雾都是备受研究界关注和工业界大量投资的领域。这些概念紧密交织在一起,描述了一个走向完全互联的星球的运动,在这个星球上,数十亿设备通过无线和有线通信基础设施的复杂网络进行交互。技术和工业的未来最引人注目的愿景是大量设备与云连接,为无数新应用程序提供平台。在这个新世界里,新公司将会出现,老牌公司将不得不彻底改变它们的商业模式。这些系统的复杂性和异质性日益增加,需要对设计用于管理它们的感知和控制平台的方式进行根本性的改变。在这次演讲中,我将重点介绍由于CPS的复杂性、异质性和功耗而带来的一些设计挑战。事实上,低功耗是设备群的基本要求,特别是在医疗保健可穿戴设备领域。再加上低成本和可靠性,任何CPS部署都必须考虑功耗。

Let's get physical: Adding physical dimensions to cyber systems
Technology advances are creating major shifts in the industrial landscape. Traditional sectors such as transportation, medical and avionics, are witnessing fundamental changes in the supply chain and in the content where the interactions between the physical world and the computing world are becoming increasingly tight. Cyber Physical Systems, Systems of Systems, Internet of Things, Industrie 4.0, Swarm Systems and The Fog are all sectors that attract massive attention from the research communities and massive investment from industry. These concepts are tightly intertwined and describe a movement towards a fully interconnected planet where billions of devices interact via a complex mesh of wireless and wired communication infrastructures. The most compelling vision for the future of technology and industry is one where a swarm of devices is connected with the cloud to provide platforms for myriad of new applications. In this new world, new companies will arise and established ones will have to change radically their business model. The increasing sophistication and heterogeneity of these systems requires radical changes in the way sense-and-control platforms are designed to regulate them. In this presentation, I highlight some of the design challenges due to the complexity, heterogeneity and power consumption of CPS. Indeed, low power consumption is an essential requirement for the swarm of devices especially in the domain of wearable devices for healthcare. Coupled with low cost and reliability, power consumption has to be taken into consideration for any CPS deployment.
