A Large Transport Aircraft Power Supply Systems, Electrical Terminals And The Load Of The Computer Simulation,

It is an inevitable trend that Distributed Power and automatic load management technologies will be applied in Advanced Aircraft Power System(AAPS). Based on the detailed analyses of Advanced Aircraft Power System construction and function, combined with the operation of MIL-STD-1553B data bus, this paper discusses the function analyses of Electric Terminal emluator and presents the realization of the simulation software.According to the function and performance of the simulation software, this paper brings forward a way to realize the multiple tasks management under the Windows circumstance based on the message drive mechanism and multithreading concept. Also, according to the real-time database and thread security class concept, the software deals with the real-time data by the means of memory database management system and improves the efficiency of the system consumedly. In adition, this paper presents the design work of Electric Terminal emluator system configuration software,which can make the simulation software own some automatization features to fit various system construction.By use of Visual C++, the Electric Terminal emluator simulation software is designed under Windows. The user interface is very frindly and it is easy to manipulate. The online debugging has been completed. The result shows the system runs reliably and has achieved functional requirement as well as good performance and the simulation process is excellent.
