中文摘要：

大天区面积多目标光纤光谱天文望远镜（LAMOST）是我国正在建造的一个世界上光谱观测能力最强的大口径兼备大视场的反射施密特光谱望远镜。LAMOST的控制系统是个分布式的系统，在这个控制系统中，各个子系统间的数据通信机制显得十分重要。本文从通信协议、通信内容格式和通信的具体方式三个方面对LAMOST的各个控制系统制定了规范。

英文摘要：

The Large Sky Area Multi-Object Fiber Spectroscopic Telescope （LAMOST） undertaken by Chinese Academy of Science is a unique astronomical instrument in combining a large clear aperture and wide field of view. Its control system is a distributed system in which the communication mechanism is very important. This paper formulates norms for every subsystem in the communication protocol, the content of the communication and the specific ways of communication.
