使用EPICS对SNS常规设施进行高级控制

Use of EPICS for High-Level Control of SNS Conventional Facilities

摘要:

SNS项目旨在将常规设施控制与其基于EPICS的加速器和目标控制系统集成。因此,EPICS将用于为SNS常规设施的所有子系统提供分布式高级别访问,包括冷却水塔、冷冻水、去离子水、HVAC、废物处理和电力监控。EPICS将为1000多个过程变量提供操作员显示和高级控制。EPICS支持将由四个使用基于PowerPC的VME总线控制器的IOC提供。低级别控制将由Allen-Bradley ControlLogix PLC提供,这些PLC将使用ControlNet进行相互通信,并使用EtherNet/IP与EPICS进行通信[2]。PLC层和EPICS层都将由工业供应商实施。文件服务器支持将基于Linux,并发版本系统(CVS)将用于管理EPICS和PLC程序和配置文件的版本控制。所有系统过程变量名称、硬件、软件和数据库配置属性将保存在Oracle主数据库中,该数据库将用于生成和维护整个项目的EPICS和PLC数据库。

英文摘要:

The SNS Project intends to integrate Conventional Facility Controls with its EPICS-based Accelerator and Target Control Systems. EPICS will therefore be used to provide distributed high-level access to all subsystems of the SNS conventional facilities, including cooling water towers, chilled water, de-ionized water, HVAC, waste processing, and power monitoring. EPICS will provide operator displays and high-level control for more than 1000 process variables. EPICS support will be provided by four IOCs using PowerPC-based VMEbus controllers . Low-level control will be provided by Allen-Bradley ControlLogix PLCs that will communicate among themselves using ControlNet and with EPICS using EtherNet/IP [2]. Both the PLC layer and the EPICS layer will be implemented by an industrial supplier. File server support will be Linux-based and Concurrent Versions System (CVS) will be used to manage version control, both for EPICS and for PLC program and configuration files. All system process variable names, hardware, software, and database configuration properties will be maintained in a master Oracle database which will be used to generate and maintain EPICS and PLC databases for the entire project.
