The Architecture Modeling of LAMOST Observatory Control System

For the complexity of the LAMOST, long time development for the LAMOST and long life-cycle of the OCS system, the OCS must have a flexible, extensible, maintainable software system. It is required that the OCS has a flexible and extensible architecture. In this paper the concepts of architecture and the OCS are introduced. Referring many kinds of architecture pattern and based on the OCS physical models, the architecture of the OCS is established which is a component-based layered system using many patterns such as the MVC and proxy. The static model and dynamic model of architecture are discussed and realized at the phase of 1 level OCS.
