摘　　要：焦面控制系统是国家"九·五"重大科学工程 lamost 天文望远镜整个控制系统的重要组成部分。本文重点描述了焦面控制系统的结构和机制,其硬件布局采用"IPC+UMAC 运动控制器+伺服电机"的方式。该系统又可进一步划分为基于 TCP/IP 协议的远程监控体系模块和以 UMAC 控制器为核心的高精度伺服控制系统模块。应用软件包括在工控机上运行的、由 VC++6.0开发的焦面监控程序和在 UMAC 上运行的、由 PMAC 语言编写的伺服控制程序。该系统的特点是高精度、可靠性、实时性和开放性结构。其中开放性结构特点又为系统的维护和升级提供了极大的便利。The focal plane control system is an important component for the entire control system of large sky area multi-object fiber spectroscopic telescope, LAMOST for short, which is one of the national large scientific projects in the Ninth Five-Year Plan. The paper focuses on the framework and mechanism of the focal plane control system with hardware layout consisting of an industrial PC （IPC）, a UMAC controller and several servomotors. The focal plane control system can further be divided into two modules, namely the remote monitoring system based on TCP/IP protocol and the UMAC-cored high-accuracy servo control system. The application includes a monitoring routine written in Visual C ＋ ＋ 6. 0 and running in the IPC, a servo control program written in PMAC＇ s language and running in UMAC. The system features high accuracy, reliability, real time and open architecture. The last feature has the advantage to further enhance the system＇ s maintainability and expansibility.
