結(jié)合北京航空航天大學(xué)自動控制系開發(fā)的某大型工程飛行模擬器系統(tǒng)，介紹了一種基于
嵌入式實(shí)時操作系統(tǒng)VxWorks和多處理機(jī)系統(tǒng)的仿真系統(tǒng)結(jié)構(gòu)及其開發(fā)環(huán)境。首先介紹了VxWorks的特點(diǎn)。然后介紹了飛行仿真系統(tǒng)的總體結(jié)構(gòu)及管理系統(tǒng)的主要功能。最后討論了實(shí)時管理系統(tǒng)實(shí)現(xiàn)中的關(guān)鍵問題，包括多任務(wù)管理在不同開發(fā)環(huán)境下的實(shí)現(xiàn)以及分布式仿真系統(tǒng)的實(shí)時數(shù)據(jù)通訊等。

w ith a large engineering flight simulation system developed by the Dcpt．of Automation Control at Beijing Univ~sity of Aeronautics and Astronaufics，this PaDel"introduces a structure and development environment of simulation system,which is based on embedded RTOS VxWorks and mult~rocessor system Characteristics of? Vxworks have been
introduced Structure of the whole flight simulation system and main function of the managem ent system have been described．Then some key tccim iques in realization ofthe managem ent system ha ve been discussed,including multitask managemen t in diferent development en v~onmen t and real-tim e communication of distributed sim ulmion system ．
