摘　　要：以我国古代著名天文学家命名的大天区面积多目标光纤光谱天文望远镜"郭守敬望远镜"(LAMOST)是我国也是世界上光谱获取率最高的望远镜。LAMOST观测控制系统(Observatory Control System,OCS)负责执行观测流程,统一协调观测过程中各子系统,并记录相关信息。在软件设计中,按照观测控制流程的需求,以网络控制系统的方式实现了分布性、实时性、可靠性和开放性的观测控制。本文介绍LAMOST观测控制系统软件的功能要求、总体设计和软件实现,并以数据采集CCDMaster(相机集总控制)为例,详述了观测控制系统的运行过程,并对观测控制系统的难点、改进升级和对可能出现的问题的措施进行了描述。The Large Sky Area Multi-Object Fiber Spectroscopic Telescope （LAMOST） is an innovative reflecting Schmidt telescope, promising a very high spectrum acquiring rate of several ten-thousands of spectra per night. The Observatory Control System（OCS） software executes observation workflow by coordinating each subsystem and recording information during observation. According to above requirements, the design of OCS is based on the concept of network control, implementing a distributed, real-time, reliable and open system. In this paper, we focus on the functional requirements, the overall design and the implementation of LAMOST＇s OCS software. As an example ,the control data acquisition by OCS through CCDMaster, a dedicated CCD camera integration control subsystem, is introduced. The paper also points out some technique difficulties and a serious of upgrade related problems in OCS develol0in~ process.
