The software-reuse technique, object-oriented technique, component and framework based software-developing methodology are used in the system architecture and implementation. The architecture of OCS is established based on a component-based layered system using many patterns such as the MVC （Model/View/Controller） and proxy. For the effective and safe exchange of commands and status between OCS and the subsystem, a unified message bus is defined and three protocols, namely a command acceptance/rejection protocol, a command execution feedback protocol and a status handling protocol, are proposed. The interface protocol between all the subsystems is defined. The full utilization of advanced computer technologies including the database, distributed computing, real-time computing, standard data exchange and expert system technologies has benefited the OCS software development.展开更多
