尽管分布式计算机系统技术已日臻成熟 ,但在飞机配电系统中的应用正在开始。本文提出了一种基于分布式计算机系统的新型飞机配电系统 ,该系统可以取代传统的常规配电和遥控式配电系统。该分布式计算机系统被称为电气负载管理系统 ( ELMS) ,由 4个电气负载管理中心 ( ELMC)、2个电源系统处理机 ( PSP)构成 ,并通过MIL-STD-1 5 5 3B总线传输数据。文中讨论了该 ELMS的结构及各 ELMC和 PSP的原理、结构。实验表明 ,应用了分布式计算机系统的飞机配电系统具有结构简单、适应性好、易于扩充等优点。
Although distributed computer system technology has matured, its application in aircraft power distribution systems is beginning to take hold. This paper presents a new type of aircraft power distribution system based on distributed computer system, which can replace the traditional conventional distribution and remote control power distribution system. The distributed computing system, known as the Electrical Load Management System (ELMS), consists of four Electrical Load Management Centers (ELMCs) and two Power System Processors (PSPs) and transmits over the MIL-STD-155B bus data. The structure of the ELMS and the principle and structure of each ELMC and PSP are discussed in this paper. Experiments show that the aircraft distribution system with distributed computer system has the advantages of simple structure, good adaptability and easy expansion.
