中文摘要：

大天区面积多目标光纤光谱望远镜（LAMOST）使用了16台低色散光谱仪、32台科学级CCD相机对目标进行光谱拍摄。CCD集总控制器MASTER是其32台CCD相机的中枢,它控制CCD按观测需要进行曝光、管理CCD状态和诊断相机故障。针对LAMOST相机系统的结构和UCAM控制器的特点,设计了MASTER系统;介绍了与OCS和UCAM接口的方式,并分析了对命令和状态的管理。

英文摘要：

The LAMOST spectral recording system consists of 32 scientific CCD cameras.This makes LAMOST different from traditional telescopes,and leads to its higher observing capability.Meanwhile,this raises challenges for controlling the CCD camera system.The MASTER software is designed as the general controller and status analyzer for the LAMOST CCD cameras.It forwards OCS commands to the cameras and collects information of states from the camera controllers.In this paper we describe the camera control software,the UCAM as used for the LAMOST.According to the OCS protocol,command and status interfaces to the OCS are incorporated in the MASTER.We describe dataflows in the MASTER for processing/managing the OCS commands and information of CCD states.Finally we show a stellar spectrum and a quasar spectrum for sample preview.The MASTER now functions properly in scientific observation.
