| 摘 要： | LAMOST(大型多天体分光望远镜)建成后将成为世界上视场最大、光谱观测效率最高的4m级口径以上的光学望远镜。它将要同时高效地观测4000颗星的光谱,这对网络控制系统的设计是巨大的挑战。该文主要从LAMOST网络控制系统构建的角度介绍了系统如何在大数据量、多任务的情况下实现各子系统控制、环境监测、授时和无线远程监控等功能,叙述了在该系统中运用的实时分布式操作系统、实时数据库,全球定位系统(GPS)和全球移动通讯系统(GSM)等多项技术．

| Abstract: | The Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) is a large scientific and engineering project in China. It will become by its completion an astronomical survey telescope with largest field of view and most efficient observation in 4-m aperture or above telescopes in the world. The telescope will be able to acquire spectrum from 4000 stars simultaneously. All these performance features have brought about a tremendous challenge for the control system design. This paper presents the network structure for the control system with mass data and multitask circumstances, focusing on the strategy how to conduct subsystem control, environmental monitoring, time service and wireless remote monitoring & controlling, etc. A number of IT technologies have been utilized in the network system, such as real time database, GPS time ticking and GSM communication. |
