可扩展性卫星任务规划系统的设计与实现

Design and Implementation of a High-extensible Satellite Scheduling System

针对现有卫星任务规划系统可扩展性差的特点,设计并实现了一种类似于HLA(High Level Architecture)框架的可扩展性卫星任务规划系统HES3(High-Extensible Satellite Scheduling System)。为保证HES3的可扩展性,提出了基于专家系统和约束分离的卫星任务规划算法的两阶段规划处理机制。设计了基于类甘特图和GIS(Geo-graphic Information System)视图的规划结果可视化人机交互接口。最后,通过一个应用实例说明了HES3的运行过程。

For the poor extensible characteristics of existing satellites scheduling systems, a high-extensible satellite scheduling system named HES3 （High-Extensible Satellite Scheduling System） was designed and implemented based on the framework similar to High Level Architecture （HLA）. A two-stage scheduling process which is composed of expert system and scheduling algorithm with constraints independence was proposed to promise the high-extensible character of HES3. Then a Graphical User Interface （GUI） was designed to illustrate the scheduling result in the form of a view similar to Gantt and a view based on Geographic Information System （GIS）. Finally, a demonstration was conducted to show how HES3 works.
