摘要： 结合国家“九五”重大科学工程项目LAMOST 望远镜总控系统研制开发的实践,着重描述了在QNX实时操作系统平台上如何通过设计优先级调度算法来协调完成多个分布式进程的机制。并以此机制为基础,对LAMOST望远镜的环境监控系统和GPS时标系统进行了设计完善。

Abstract: In association with the research and development of the control system for LAMOST, which is one of the national large scientific projects, this paper focuses on the mechanism of scheduling algorithm for distributed multi-process priority on the QNX real-time operating system platform. Furthermore, based on the mechanism the design of the GPS timescale control system and environment parameter control system are optimized.
