The mapping mechanism between Distributed Integrated Modular Avionics and data distribution service

With the highly integrated and modularize development of avionics systems, new generation of avionics systems have stepped into the stage of integrated modular avionic (IMA, Integrated Modular Avionic). Aiming for shortcomings of the IMA, distributed integrated modular avionics (DIMA, Distributed Integrated Modular Avionics) combined the design characteristics of joint architecture and IMA architecture, and it has become the hot spot research of today. For building DIMA simulation platform and allowing each DIMA nodes connected, this paper puts forward a mapping mechanism of DIMA underlying communication with data distribution service (DDS, Data Distribution Service), and builds simulation platform to validate its feasibility. Through the simulation, we find the mapping mechanism can meet the requirements of IMA distributed interconnection, and provides a feasible method for communication of all DIMA nodes to build DIMA simulation platform.
