Software Defined Automation Platform (SDAP) - revised

物联网(IoT)是物理设备、车辆、建筑物和其他信息源之间的互联，这些信息源嵌入了电子设备、软件传感器、执行器和网络连接，使这些对象能够收集和交换数据。与智能服务一起，使他们能够处理物理和虚拟世界的信息并做出反应，这构成了推动当前数字革命的新技术现象之一。一个主要需求是为时间关键型工业监控应用提供强大的实时解决方案。在此之前，需要为单个设备提供远程操作控制重要流程的能力，并整理来自多个设备的数据，为预测性决策提供大数据分析。这是工业物联网(IIoT)。由于几个原因，目前安装的(工业)控制系统主要是封闭的和专有的。这与它们下面的开放、可互操作的仪器设备网络和上面的典型自动化层次结构中的信息技术(IT)系统形成了对比。封闭的专有系统升级和维护成本高昂，在尝试插入新技术时具有挑战性，特别是来自第三方的技术。(来源：Open Process Automation(Tm)业务指南)。通过提供在商用硬件上运行的软件定义的解决方案，能够对整个资产进行远程更新，这些问题得到了解决，从而节省了成本并长期信任供应。该项目将交付：·支持时间关键型应用程序的虚拟工作负载的灵活开放解决方案·简化的“监控和数据采集”(SCADA)集成。·支持一系列时间关键型用例，包括闭环控制、工业数据推理、和虚拟PLC应用程序·可扩展的集装箱化配置，使已部署的系统能够随着其他应用程序的部署而发展·解决方案可以使用最新的英特尔和ARM超低功耗片上系统(SOC)处理器我们的目标是实现独立于芯片、操作系统、硬件和应用程序提供商；该解决方案将在高度嵌入式设备上独立运行，或与其他基于Edge的系统一起提供。最初的参考实现是Linux Foundation的EdgeX开放式物联网边缘平台的扩展，但最终该解决方案可以为其他边缘平台提供时间关键型扩展，例如AWS GreengrassEdgeX是一个供应商中立的开源项目，为工业物联网(IIoT)和边缘计算构建通用开放框架。EdgeX得到了广泛的采用和广泛的行业支持，它提供了一个极好的参考平台，可以在此平台上验证该项目的输出。

The Internet of Things (IoT) is the inter-networking of physical devices, vehicles, buildings, and other information sources embedded with electronics, software sensors, actuators and network connectivity which enable these objects to collect and exchange data. Together with the intelligent services to allow them to process information of the physical and the virtual world and react, this forms one of the new technological phenomena driving the current digital revolution.A major need is to have a robust, real time solution for time critical industrial monitoring and control applications. This follows the need to provide individual devices with the ability to operate remotely controlling vital processes, and collate data from many devices feeding big data analytics for predictive decision making. This is the Industrial IoT (IIoT).For several reasons, currently installed (industrial) control systems are predominantly closed and proprietary. This contrasts to the open, interoperable network of instrumentation devices below them and the Information Technology (IT) systems above in the typical automation hierarchy.Closed, proprietary systems are expensive to upgrade and maintain, and challenging when trying to insert new technology, especially from third parties. (Source: The Open Process Automation(tm) Business Guide).By providing software defined solutions running on commodity hardware, capable of remote updates to an entire estate, these issues are addressed offering costs savings and long-term confidence of supply.This project will deliver:•A flexible open solution supporting virtualized workloads for time-critical applications•A simplified "Supervisory Control and Data Acquisition" (SCADA) integration.•Support a range of time-critical use cases including closed loop control, industrial data inference, and virtualized PLC applications•Extensible containerized provisioning enabling a deployed system to evolve as additional applications are deployed•A solution that can use the latest Intel and ARM ultra-low power System-On-a Chip (SOC) processorsOur objective is an implementation independent of silicon, operating system, hardware and application provider; the solution will run stand alone on highly embedded devices or be delivered in conjunction with other Edge based systems. The initial reference implementations are an extension to the Linux Foundation's EdgeX open IoT Edge Platform, but ultimately the solution could provide time-critical extensions to other Edge Platforms e.g. AWS GreengrassEdgeX is a vendor-neutral open source project building a common open framework for Industrial IoT (IIoT), edge computing. EdgeX is seeing wide scale adoption and broad industry support, it provides an excellent reference platform on which the output of this project can be validated.
