1.56m望远镜滤光片定位及副镜调焦的电控改造

摘要

从硬件和软件方面详细阐述了1.56m望远镜滤光片定位及副镜调焦电控部分的改造情况及新系统的技术实现.通过此次更新改造,去掉了原来的滤光定位和副镜调焦独立的控制操作台,将其精简成独立的电控板卡,经ISA插槽嵌入到主控制计算机.人机互动操作界面更直观、易于操作,减轻了观测人员的工作强度.并使电控系统故障率大大减少,使望远镜的观测时间得到有效的保障,也使望远镜的能力得到充分的施展.%From the view point of hardware and software design, the technical update of 1.56m telescope electrical control system for filter orientation and secondary mirror focusing are introduced. Instead of outdated console and chassis, two new and compact control cards are developed and integrated with host computer via ISA bus. The manipulation interface is more intuitionistic and is easy to be operated. The new system has less fault, and it can guarantee the telescope observation time and take full advantage of this 1.56m telescope.
