摘要
随着现代计算机技术和电子技术的发展以及多电飞机对新型配电系统的需求,分布式电气负载智能管理成为先进飞机电气系统发展的方向;电气系统处理机(PSP)是先进飞机电气系统的核心,负责实时负载调度、管理,系统故障处理、恢复和系统动态重构;以某型飞机为背景,首先论述了电气系统处理机的功能,搭建了合适的系统软硬件平台,并在这个基础上进行了详细任务级设计;然后讨论了改进电气系统处理机软件可靠性的措施以及BIT技术在电气系统处理机上的实现方法;实验情况表明系统能够实现多任务可靠调度,能够满足先进飞机对电气系统的可靠性、实时性等要求。
Along with the rapid development of modern computer and electronic technology and the request for new electrical power sys- tem of more electrical airplane, distributed electrical loads auto - management becomes the new direction in advanced aircraft electrical system. As the kernel of aircraft electrical system, Power System Processor （PSP） implements electrical load scheduling and management, system fault process and fault recovery, system rebuilding. First, in this paper, the basic function is discussed and the proper platform including software platform and hardware platform is built, on the basis of this the details design on the stage of task is performed; second some steps to improve the reliability of software and the BIT technology＇ s implement on PSP are discussed. The experiment results show that system runs robustly and the real time response, reliability are guaranteed, stratifies the request of the advanced aircraft eleetrical system.
