综合化飞行器管理计算机技术研究

Research on Integrated Vehicle Management Computer

目前国外新一代飞机的设计中,为进一步提高飞机的性能,同时降低系统费用,采用飞行器管理系统综合管理包括飞行控制、发动机控制、机电公共设备管理等飞机平台的功能。飞行器管理系统核心是飞行器管理计算机,细粒度可配置飞行器管理计算机不同于以往基于通道容错的计算机系统,它是基于模块级容错的计算机系统,细粒度可配置飞行器管理计算机设计利用综合化技术,通过采用通用的、标准的模块,提高系统的可靠性和可用性。它既要具有飞行控制系统的多余度安全,同时又需要满足发动机控制、机电管理等不同系统、不同余度配置的安全要求。另一方面飞行器管理计算机从系统结构、容错技术等方面要适应不断变化的微电子技术和计算机技术的发展,保持飞机平台具有相对的稳定性,更要具有灵活的系统配置能力。主要介绍了细粒度可配置飞行器管理计算机体系结构、软件要求、容错结构的实现。

In order to meet the need of the airborne electronic system, the design of new style vehicle system adopts an integration of flight control, engine control, utilities control,etc, to provide high performance well as to lower the life- cycle cost. The key of VMS is vehicle management computer. The fault tolerant of management of system as configurable fine grain vehicle management computer do not base on channel but module. It adopts an integration of technology and thus matches the architecture with the reliability and availability targets by utilizing common standard module and enables different functions to be implemented at different redundancy levels. Otherwise it should adapt well to the change of microelectronics and computer technology at system architecture and fault tolerant. This paper presents the implementation of the system architecture, the software requirement, and the fault tolerance structure of the new style vehicle management computer.
