摘　　要：网络控制系统非固定执行时间的调度策略是基于先进控制理论的反馈调度策略,其策略是并行计算减少算法的执行时间来获得更高的计算效率,解决更复杂的问题并加快求解过程。文中着重从NCS调度数据分类、优先级、系统调度分析、方法四个角度进行分析,得出气象业务网络系统性能的优化映射为较低层次的系统参数优化、网络控制系统的稳定运行是准确做出天气预报并及时服务的基本保证,网络的开放性和共享性在方便人们使用的同时,气象信息网络调度应尽量避免信息的冲突和拥塞现象的发生,力求达到系统设计与网络实现的总体性能优化的目标。Network control system scheduling strategy of fixed execution time is a feedback scheduling strategy based on the theory of the advanced control, adopting parallel computing to reduce algorithm execution time gains higher computational efficiency to solve the more complex problem and the solution is to speed up the process. In this paper, emphatically from NCS scheduling data classification, priority, system scheduling analysis and methods, conduct an analysis and get that the system parameter optimization of lower levels of meteoro- logical operational network system performance optimization mapping and the stable operation of the network control system is the basic guarantee to accurately make a weather forecasting and the timely service, network＇ s openness and sharing in convenience for the people, at the same time, the meteorological information network scheduling should try to avoid conflict and congestion, reaching the goal of overall performance optimization of the system design and network realization.
