Design And Implementation Of Integrated Avionics Dataloading System Based On1553B Bus

Integrated avionics dataloading system, as an important part of theintegrated avionics system, plays an important role in the implementationof the mandate of the plane. In order to improve dataloading speed andlaunching speed of the plane, high-speed, high-reliability integratedavionics dataloading system has become a focus in the integrated avionicssystem.According to the existed equipment, it is studied the core technologyof the Integrated avionics dataloading system, such as the1553B busprotocol, the ARM processor and FPGA. Based on the function of theIntegrated avionics dataloading system, it’s determined the specificsystem implementation. It’s proposed the overall design of integratedavionics dataloading system based on the1553B bus protocol. On thebasis of this program, according to the system to achieve the function, it’sproposed the main technical indicators, and10common design principles.The indicators of the system meeting the design requirements accordingto the online experiment, flight experiment, high and low temperatureexperiments, it’s proved the correctness and feasibility of the proposeddesign.
