A monitoring unit and monitoring method for an airborne synthetic vision guidance system

Abstract

The invention provides a monitoring unit for an airborne synthetic visual guidance system, the monitoring unit includes a display module and a monitoring module; the monitoring module is used for real-time monitoring of the display module; the display module includes an alarm display sub-module and sequentially connected database, graphic generation sub-module and graphic display sub-module; the monitoring module includes sequentially connected navigation deviation calculation sub-modules, monitoring algorithm processing sub-modules and monitoring result feedback sub-modules; the graphic display sub-module is connected with the monitoring algorithm processing sub-module ; The alarm display submodule is connected with the monitoring result feedback submodule. Using instrument landing system and radio altitude information as the source of monitoring information, through real-time calculation, monitor the display information of SVGS and feed back the results to the pilot through an independent channel, improve the safety of the synthetic visual guidance display system and reduce the probability of misleading , so that the synthetic vision guidance display system can meet the airworthiness requirements.

Description

technical field [0001] The invention belongs to the monitoring technology of an airborne synthetic visual guidance system, and relates to a monitoring unit and a monitoring method suitable for the airborne synthetic visual guidance system. Background technique [0002] During critical flight phases such as takeoff and approach, the visual limitation of pilots is one of the main factors of serious flight accidents worldwide. In order to solve this problem, research institutions of various countries have invested a lot of manpower and material resources in developing new aircraft cockpit display technology. It is against this background that the synthetic vision guidance display system emerges as the times require. [0003] The Synthetic Visual Guidance Display System (SVGS) combined displays flight guidance information and supports high-precision monitoring. The synthetic vision guidance system provides real-time 3D terrain exterior images, including images of obstacles and...
