Abstract:

Based on the analysis of the merits and demerits of the existing monitor and control system models（MCS） of satellite earth stations, and based on their openness, integrity and efficiency, we use the component-based software engineering technology and propose a new model of MCS, which has a clear hie rachy, standardized interfaces, brief interconneetions and easy expandability. We also analyse the functions of the components in this new model and thecommunications between them. It is easy for the system model to implement practical systems with a flexible structure and strong openness. Meanwhile, s oftware reuse is easy to be implemented based on components.

Key words: component, three-level structure, software reuse, object-oriented software engineering
