More Electric Aircraft Power Supply Processor And Load Management Center

Power System Processor (PSP) and Electric Load Manage Center (ELMC) are important research fields of the power distribution for more electrical airplanes . The power distribution system for more electrical airplanes is a mixed-mode power system, in which the new Electrical Multiplexing, distributed control and concentrated management are used. The Electric Load Manage Center controls electrical loads, and the Power System Processor controls the whole electrical system . The power distribution system realizes effectively load automatic management .The purpose of the paper is not only to analyse 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 emphasis 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 priority .The hardware platform of system development is PC 104 and the software platform is @C/OS-II. According to the function of Power System Processor , several tasks to make @C/OS-II attempered and managed are designed .
