Advanced Aircraft Electrical System Of The Main Implementation Of Software And Design,

Aircraft's automatic power supply system is one of the key technologies to improve aircraft's performance. As the kernel of the aircraft's power distributed system, Power System Processor (PSP) is responsible for management and control of aircraft's electrical loads.The dissertation focuses on researching and designing the chief execution softeware, which will offer PSP a high performance and high stability software system.Based on the Real-Time Operating System (RTOS) VxWorks, a PC/104 486DX embedded computer is employed in the project. After making a detailed survey of scientific methods widely used in designing embedded system, such as software and hardware co-design, PetriNet and so on, they are applied to make the development more scientific and standard. The application of RTOS is another emphasis. The dissertation discusses the Board Support Package (BSP) technology and finishes the Controller Area Network (CAN) PC/104 adapter device driver program for VxWorks operating system.Concerning reliability problems , the dissertation offers solutions employed in the project which will ensure the software reliability. To form an integrate chief execution software development process, software test technology is introduced as an supplement.As a result, the software executes reliably and stably on the hardware structure. Software prototype development has been accomplished.
