Design and application of universal bus driver software for avionics systems

In consideration of the existing problems of bus driver software in avionics simulation system,such as single function,poor scalability and immoderately repeated development,and according to the features of data driven in avionics simulation system,this paper puts forward a design and implementation scheme of bus driver software for avionics simulation system,which is easy to expand,flexible to configure and stable to run. This scheme bases on the object-oriented design principle,and uses a layered software architecture and modular design. It takes advantage of the flexibly of extensible markup language(XML) and the dynamics and transmission advantage of publish/subscribe data distribution networks. Thus,the versatility and flexibility of the scheme are guaranteed and the robustness and reusability of the software are enhanced. In conclusion,through the design of this scheme,bus driver software remarkably improves the efficiency of multi-bus data distribution in the avionics simulation environment.
