针对天象仪传统控制方法存在的问题，本文提出一种基于CAN 总线，应用组态软件技术的控制系统。不仅使天象仪的操作更加简单，而且可降低开发成本、缩短开发周期。关键词：天象仪CAN 总线组态软件Abstract: Aimed at problems of control method in space planetarium system, this paper proposes a control system based on CAN-bus and used software of configuration. It not only makes the operation of space planetarium more simple, but also cans lower development cost and shorten the development period.Key words: Space planetarium，CAN-bus，Software of Configuration
