Abstract
In order to solve the resource conflict and systematic coupling problem that the integration of onboard process system platform brings, the integration of mechanical and electronical system was promoted, distributed integration modular avionics system (DIMA) was used, the process modular was distributed near to signal source, the big cabinet of integrated avionics system was replaced using distributed small cabinet of DIM A, these small cabinets were connected using high speed data bus, the avionics full duplex switched ethernet(AFDX) , time-trigger ether-net (TTE network) and ethernet passive optical network(EPON) were selectively analyzed in the application of DIMA system, and theirs technology characteristic were compared, it's advantage and characteristic based on AIRBUS DIMA system were analyzed based on the architecture of DIMA. By using the architecture of DIMA, the resource conflict and systematic coupling problem can be resolved, at same time, the structure of back board of process cabinet can be simplified, can be widely used in civil aircraft.关键词
