【Abstract】 The main subsystems of ELV (electronic low voltage) information system of civil airport and the communication relationship among subsystems are introduced. The existing system architectures and their advantage and disadvantage are analyzed. The system architecture based on the middleware service layer applying to civil airport information system is presented. In this system, a three-layer architecture is built, and the maintainability and extensibility of system are improved.更多还原
