【摘要】：传统工业自动化层级结构比较复杂,集成化程度不高,逐渐无法满足信息化、智能化的发展需求。云计算作为一种新型的技术,以其创新的服务模式逐渐应用到各个行业,如智能交通、电子政务、金融业等,并取得了同时良好的应用效果。工业自动化也是云计算应用的一个重要领域,同时,政府陆续出台政策,大力推进工业化与信息化深度融合,因此将云计算技术与工业自动化相结合的工业云将成为新的研究热点。本文首先介绍了云计算的概念,对多个主流的云平台进行了分析,剖析了工业云体系架构及其关键技术。接着,本文对OpenStack云平台进行了详细的介绍,包括其核心组件与工作原理,详细阐述了本文在部署OpenStack私有云平台时的硬件部署架构以及软件部署方式。通过将工业软件与云计算平台的结合,提出了一种基于OpenStack的工业云平台架构,介绍了该工业云平台架构的实现方法。为了验证所提的工业云平台架构的可行性,本文以四容水箱系统为被控对象,在工业云平台上借助于云主机上部署的工业软件STEP7、WinCC等实现了数据采集、画面监控的效果,其中重点介绍了云主机与S7-300PLC的通讯连接问题。并借助于云主机上搭建的Simulink控制模块,对四容水箱进行了实时控制。最后,在工业云平台上,基于西门子MES软件SIMATIC IT进行了 MES系统部分功能的开发,在SIMATICIT中利用RTDS组件对四容水箱的状态实时监控,并对WinCC中的状态进行了指令下达,实现了MES系统对DCS系统的控制。利用HDD组件对四容水箱进行了历史曲线的绘制与分析,借助于CAB组件,开发了四容水箱的Web监控界面,在Web监控界面中,可以监控四容水箱的实时数据、历史曲线等信息,并对开发的Web界面做了 IIS发布,达到了同一子网下的云主机均可访问此Web监控界面的效果。本文以四容水箱为被控对象,在工业云平台上实现了数据采集、实时控制、Web监控的功能,论证了所提的基于工业云的控制系统的可行性。
[Abstract]:The hierarchical structure of traditional industrial automation is complex, and the integration level is not high, which can not meet the development needs of information and intelligence. Cloud computing as a new technology, with its innovative service model gradually applied to various industries, such as intelligent transportation, e-government, finance and so on, and achieved good results. Industrial automation is also an important area of cloud computing applications. At the same time, the government has successively issued policies to vigorously promote the deep integration of industrialization and information technology. Therefore, the industrial cloud which combines cloud computing technology with industrial automation will become a new research hotspot. This paper first introduces the concept of cloud computing, analyzes several mainstream cloud platforms, and analyzes the industrial cloud architecture and its key technologies. Then, this paper introduces the OpenStack cloud platform in detail, including its core components and working principles, and describes in detail the hardware deployment architecture and software deployment mode of this paper when deploying OpenStack private cloud platform. By combining industrial software with cloud computing platform, an industrial cloud platform architecture based on OpenStack is proposed, and the implementation method of the industrial cloud platform architecture is introduced. In order to verify the feasibility of the proposed industrial cloud platform architecture, this paper takes the four-tank system as the controlled object, and implements the effect of data acquisition and picture monitoring on the industrial cloud platform with the help of industrial software STEP7WinCC deployed on the cloud host. The communication connection between cloud host and S7-300PLC is introduced in detail. With the help of the Simulink control module built on the cloud host, real-time control of the four-tank is carried out. Finally, on the industrial cloud platform, based on Siemens MES software SIMATIC IT, some functions of MES system are developed. RTDS components are used in SIMATICIT to monitor the state of four-tank in real time, and the state of WinCC is ordered. The control of MES system to DCS system is realized. The history curve of the four-tank is drawn and analyzed by using HDD component. With the help of CAB, the Web monitoring interface of the four-tank is developed. In the Web monitoring interface, the real-time data and historical curve of the four-tank can be monitored. The developed Web interface is published by IIS, and the result is that the cloud host can access the Web monitor interface under the same subnet. This paper takes the four-tank as the controlled object, realizes the function of data acquisition and real-time control of Web monitoring on the industrial cloud platform, and proves the feasibility of the proposed control system based on industrial cloud.
