Automatic flight control device

Abstract

The invention relates to an automatic flight control device, which adopts a dual-channel full-digital design and communicates with an automatic flight control computer through an HB6096 bus interface.The automatic flight control device comprises a panel combination unit, a power supply unit, an interface encoding and decoding unit, a core processing unit, a channel logic and input and output unit, a display driving and backlight unit. The device adopts the double-channel full digital design, the usability, testability and task reliability of the automatic flight control device are greatly improved; the electrical interface adopts a bus interface to replace the traditional discrete quantity interface, so that the interface is simple, the signal transmission reliability is improved, and theweight is reduced; and a combined knob is adopted, so that the panel is simple, and the man-machine work efficiency is improved.

Description

Technical field [0001] The invention belongs to the technical field of aviation automatic flight control, and specifically relates to an automatic flight control device. Background technique [0002] The existing automatic flight control devices of domestic aircraft have relatively simple functions and structures, and are suitable for small and medium-sized aircraft, and do not meet the requirements of complex automatic flight control systems for large aircraft. In the current domestic large-scale transport aircraft, there is no autonomously developed automatic flight control device with complex structure and redundancy. [0003] The function settings and interfaces of automatic flight control devices of some large foreign aircrafts do not meet the requirements of the current domestically developed automatic flight control systems for large aircrafts, and they have the disadvantages of large size and heavy weight. Summary of the invention [0004] The purpose of the present inventi...
