Monitoring unit and monitoring method for airborne synthetic visual guidance system

Abstract

The invention provides a monitoring unit for an airborne synthetic visual guidance system. The monitoring unit comprises a display module and a monitoring module, wherein the monitoring module is usedfor monitoring the display module in real time, and the display module comprises an alarm display sub-module, and a database, a graph generation sub-module and a graph display sub-module which are connected in sequence. The monitoring module comprises a navigation deviation calculation sub-module, a monitoring algorithm processing sub-module and a monitoring result feedback sub-module which are connected in sequence; the graph display sub-module is connected with the monitoring algorithm processing sub-module; and the alarm display sub-module is connected with the monitoring result feedback sub-module. An instrument landing system and radio altitude information are used as monitoring information sources; the display information of the SVGS is calculated and monitored in real time, and a result is fed back to a pilot through an independent channel, so the safety of the synthetic visual guidance display system is improved, the misguidance probability of the synthetic visual guidance display system is reduced, and the synthetic visual guidance display system can meet 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...
