欧洲核子研究中心的控制系统由多层硬件和软件组成，从部署在机器附近的硬件延伸到运行在操作人员用于控制和监视的计算机上的软件。一种新的集中支持的服务正在为离加速器最近的层开发：分布式I/O和现场总线，针对无辐射和辐射暴露区域。该项目的一个关键方面是为层选择工业标准，目前主要是定制的，内部设计的解决方案。关于分布式I/O层，本文描述了我们如何调整一个工业板条箱标准，使其适合作为低成本的模块化硬件平台，用于辐射暴露和无辐射区域的远程模拟和数字I/O应用。我们正在设计一种低成本的3U机箱，它具有标准化的背板，附带一个耐辐射的开关模式电源和一个基于fpga的系统板，该系统板容纳现场总线通信接口。
The CERN control system is comprised of multiple layers of hardware and software that extend from the hardware deployed close to the machine, up to the software running on computers that operators use for control and monitoring. A new centrally supported service is being developed for the layers closest to the accelerator: Distributed I/O and the Fieldbus, targeting both radiation-free and radiationexposed areas. A key aspect of this project is the selection of industrial standards for the layers, which are currently dominated by custom, in-house designed solutions. Regarding the Distributed I/O layer, this paper describes how we are adapting an industrial crate standard to be suitable as the low-cost modular hardware platform for remote analog and digital I/O applications in radiation-exposed as well as radiation-free areas. We are designing a low cost 3U chassis with a standardized backplane accompanied by a radiation tolerant, switched-mode power supply and an FPGA-based System Board that houses the Fieldbus communication interface.
