【摘要】 测控站监控系统由于系统规模小、设备复杂,缺少商业化控制软件的支持,因而建造成本高,周期长,缺少灵活性和扩展性,系统维护困难,不适应航天技术发展的需要。通过分析测控站监控与一般工业控制的差别,借鉴组态软件设计思想,设计面向对象的设备对象模型和显示模型,为设备对象定义设备参数、数据处理函数、通信接口参数等属性,为显示元素定义静态和动态的图形属性、显示方法以及与设备对象的关联。依据配置文件,在运行时,生成设备对象,完成设备数据的接收、处理和控制;每个显示配置文件形成一幅显示画面;显示元素通过关联的设备参数更新显示属性。这种方法为在特定领域内构建监控系统提供了经济实用的解决方案。更多还原

【Abstract】 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.更多还原
