在过去的几年里，欧洲南方天文台 (ESO) 与其他欧洲天文机构合作，开始了针对 E-ELT（欧洲极大望远镜）仪器和后焦自适应光学器件的多项可行性研究。目标是创建一套灵活的仪器来解决天文学家希望在未来几十年内解决的各种科学问题。在此框架下，的里雅斯特天文台（INAF-AOTs）目前负责对三种仪器的电子和控制软件架构进行分析和初步研究：CODEX（控制软件和电子）和OPTIMOS-EVE/OPTIMOS-DIORAMAS（控制软件）。为了应对这些仪器日益增加的复杂性和对稳定性、精度、实时延迟和子系统之间通信的新要求，我们小组研究了新的解决方案。在本文中，我们提出了基于以组件/容器模型为中心的分布式通用框架的软件和电子架构，该框架使用 OPC 统一架构作为标准层与三个不同供应商的 COTS 组件进行通信。我们描述了我们实验室中建立的三个工作原型，并讨论了它们的性能、集成复杂性和部署的简易性。
During the last years the European Southern Observatory (ESO), in collaboration with other European astronomical institutes, has started several feasibility studies for the E-ELT (European-Extremely Large Telescope) instrumentation and post-focal adaptive optics. The goal is to create a flexible suite of instruments to deal with the wide variety of scientific questions astronomers would like to see solved in the coming decades. In this framework INAF-Astronomical Observatory of Trieste (INAF-AOTs) is currently responsible of carrying out the analysis and the preliminary study of the architecture of the electronics and control software of three instruments: CODEX (control software and electronics) and OPTIMOS-EVE/OPTIMOS-DIORAMAS (control software). To cope with the increased complexity and new requirements for stability, precision, real-time latency and communications among sub-systems imposed by these instruments, new solutions have been investigated by our group. In this paper we present the proposed software and electronics architecture based on a distributed common framework centered on the Component/Container model that uses OPC Unified Architecture as a standard layer to communicate with COTS components of three different vendors. We describe three working prototypes that have been set-up in our laboratory and discuss their performances, integration complexity and ease of deployment.
