基于VxWorks的飞机电气处理机多任务程序设计

摘要

The core processor of the solid-state electric distribution system, also known as the power system processor (PSP), is the control center of solid-state eletric distribution system. In order to make the PSP to work accurately, efficiently and reliably, a multi-task control program for the processor was developed for the dual PSP hot backup mode under VxWorks platform. A detailed classification and analysis of multi-tasking system were conducted emphatically. The in-depth study on the dual-system hot backup function were carried out. The tests on the hardware platform indicate that the program works well, and can meet the demands of automatic electric distribution of multi-tasking system.%固态配电系统核心处理机也称作电气系统处理机(PSP),是固态配电系统的控制中心.阐述了在VxWorks下飞机固态配电核心处理机的多任务程序设计流程,对多任务进行了细致的划分和分析,并且针对双机热备份的功能进行了深入的研究.
