Research on Application of Design Pattern on TT&C Flow
Sun Cai-ying · 2009
Design pattern is the solution for some special issues, and the solution template can be set up with it. Combined with object-oriented design, design pattern could formulate system design and implementation, and enhance the multi-purpose ability of system that could improve the design efficiency of system. First, this paper describes the main workflow of spaceflight TTC system and presents main issues in system automation. And then, it introduces the state pattern inside the design pattern, details the applications of state pattern in automatic software workflow of TTC system and puts forward the characteristics and adaptability of state pattern.
