散斑中子源前端控制系统的现状
Status of the Control Sytem for the Front-End of the Spallation Neutron Source
摘要：
Spanish中子源（SNS）是六个实验室之间的合作伙伴关系。为了确保真正的综合控制系统，已商定了许多标准，包括使用EPICS作为基本工具包。然而，合作伙伴关系中的独特之处在于，要求负责构建前端的劳伦斯伯克利国家实验室在将其运送到橡树岭国家实验室（ORNL）之前在当地进行操作。因此，它的控制系统必须在2001年完成，远远早于2006年SNS的完成日期。因此，在其他五个合作伙伴完成设计之前，必须做出关于接口硬件、操作员屏幕布局、设备类型等的许多决定。在某些情况下，前端已经默认定义了一个标准;在其他情况下，升级到一个新的标准是由ORNL预期以后。几乎所有的前端设备都已与EPICS控制系统一起调试。在所需的约1500个信号中，约有60%现已投入日常运作。该控制系统基于“标准架构”;然而，它具有现场总线主导的布局。本文将讨论一些独特的接口要求，导致新的设备系列添加到EPICS的剧目。它还将描述对所有主要领域所作的选择和权衡。
英文摘要：
The Spallation Neutron Source (SNS) is a partnership between six laboratories. To ensure a truly integrated control system, many standards have been agreed upon, including the use of EPICS as the basic toolkit. However, unique within the partnership is the requirement for Lawrence Berkeley National Lab, responsible for constructing the Front End, to operate it locally before shipping it to the Oak Ridge National Lab (ORNL) site. Thus, its control system must be finished in 2001, well before the SNS completion date of 2006. Consequently many decisions regarding interface hardware, operator screen layout, equipment types, and so forth had to be made before the other five partners had completed their designs. In some cases the Front-End has defined a standard by default; in others an upgrade to a new standard is anticipated by ORNL later. Nearly all Front-End devices have been commissioned with the EPICS control system. Of the approximately 1500 signals required, about 60% are now under daily operational use. The control system is based on "standard architecture"; however, it has a field-bus dominated layout. This paper will discuss some unique interface requirements that led to adding new device families into the EPICS repertoire. It will also describe the choices and trade-offs made for all major areas.
