Advanced Aircraft Electrical System Computer Control Technology Research

Power System Processor (PSP) and Electric Load Manage Center (ELMC) are the important contents of research of the power distribution for more electric airplanes . The power distribution system for more electric airplanes is a mixed-mode power system, which applies a new technology called Electrical Multiplexing. This system uses the means of distributed control and concentrated management. The Electric Load Manage Center controls electrical loads, mean- while the Power System Processor controls the whole electrical system . The power distribution system realizes effectively load automatic management.The main purpose of this thesis is not only to analysis and research the Power System Processor and the Electric Load Manage Center ,but also to design the scheme of the Power System Processor and the Electric Load Manage Center. The emphases is to analysis the software design of the Power System Processor in detail. The content of software design includes the transplant and apply of RTOS ,. the establishment of interrupt mechanism about serial communication , the realization of system function , the real-time data processing and the setting and management of task prior .The hardware platform of system developmeng is PC104 and the software platform is μC/OS-Ⅱ. Based on this and according to the function of Power System Processor , We designden several tasks to make μC/OS-Ⅱ attemper and manage them .
