Modeling A320 EIS based on UML

With avionics system getting more sophisticated, Electric Instrument System simulation has become an important component of the aero plane simulator that it can enhance the simulators' authenticity and effectiveness. Based on line maintenance, the architecture of A320 Electric Instrument System is established. A UML modeling methodology is applied while object-oriented analysis to the system is done. The Airbus A320 EIS' analysis of functional requirements is met by Use Case Diagram. The design with class and package is used to establish a static structure model of EIS. Both Statechart Diagram and Sequence Diagram are used to establish a dynamic model of EIS. According to these above, a concise, clear and feasible technical solution is provided for implementation of the system function.
