Airborne warning control light box and its light alarm method

Abstract

The invention provides an airborne warning control light box and its light warning method. The method comprises the steps of conducting filtering and anti-shake treatment to positive control or negative control discrete warning signals; determining whether the discrete signals processed by a pre-processing module meet warning requirements; based on an input interface of the discrete signals, determining malfunction information to which the signals belong, outputting the discrete signals to a warning light display unit and an indicating light control unit corresponding to the malfunction information to control the light-on and light-off of a indicating light. According to the airborne warning control light box, the control unit centered around a digital signal processor and PLC devices is used, the conventional warning light box and an warning computer are integrated to miniaturize airborne warning equipment and make the airborne warning equipment more integrated.

Description

technical field [0001] The invention belongs to the field of aviation electrical design, and in particular relates to an airborne warning control light box and a light warning method with the light box. Background technique [0002] Lighting warning technology is to make the aircraft send out warning information when it is in a dangerous state, reminding the pilot to take necessary measures. It is a must-have function for modern aircraft to ensure flight safety, and it is also an important guarantee for giving full play to its combat effectiveness. Analyzing the previous aircraft design, one is the form of light warning, in which the warning information is discretely distributed in a certain area of ​​the instrument panel and console, without integration, which increases the burden of pilot observation and the response time for taking measures. One form of light alarm is that although the alarm information is integrated and displayed in the alarm light box, the alarm light b...

AI Technical Summary

Problems solved by technology

One form of light alarm is that although the alarm information is integrated and displayed in the alarm light box, the alarm light box only has a single signal display function, and cannot judge and process external signals, and cannot accurately locate faults. The cross-linking of internal sensors and airborne electronic equipment is complex, and it is easy to connect currents to each other, causing problems such as false or false lighting of warning lights, false lighting of electromechanical or integrated displays, etc., resulting in increased probability of misjudgment of operations
