Research and Development of Software Architecture for TTC Station Monitoring & Control System
Liu Qing-pu, Jian Wang · Jisuanji fangzhen · 2006
The current monitoring and control system in TTC station does not fit with the rapid development of space technology due to its mass cost,long development period,less flexibility,hard maintenance caused by without enough commercial software support,its small scale and the complicated TTC equipment.The difference between TTC station system and normal industrial control system is analyzed.According to configurable software design,object-oriented equipment model and display model are deduced.Equipment parameter,data process method,communication channel are defined for the equipment object while both static and dynamic graphic attributes,display style and the relationship with equipment parameter are defined for the graphic object.When the system runs,equipment objects are created to handle data receiving,data processing and command sending according to protocols.Monitoring display consists of graphic objects which are defined in display configuration file.A graphic object changes its display attributes according to the related equipment parameters.This is an economical solution for constructing monitoring and control system in such special application fields.
