简介解决航空电子设备综合的各种系统方法要求在飞机各分系统、处理和计算部件、座舱显示器及控制器之间具有有效和可靠的数据传输。目前采用的措施是利用时分制多路传输数据总线来分配全机的信息。MIL-STD-1553A 规定了信息结构和指令响应规范。为了保证所有总线上传输的数据的完整性,多路传输系统必须能处理所有检出的信息差错和终端硬件故障。本文介绍多路传输系统工作和控制、信息差错和终端故障的检出以及控制过程的作用原理,此控制过程是为了集中地管理该信息规范使误差信息恢复正常,和因终端故障而可重新按置。
INTRODUCTION The various system approaches that address the avionics synthesis require effective and reliable data transfer between the aircraft subsystems, processing and computing components, cockpit displays and controllers. The current measure is the use of time-division multiplexing data bus to distribute the whole machine’s information. MIL-STD-1553A specifies the message structure and command response specification. In order to ensure the integrity of the data transmitted on all buses, the multiplex system must be able to handle all detected information errors and terminal hardware faults. This article describes the principle of multiprocessor system operation and control, error detection and detection of terminal errors, and control procedures. This control procedure is intended to centrally manage the message specifications so that error messages are returned to normal, Set.
