Embodiment Construction

[0055] refer to figure 1 The overall implementation flow chart of the system, a fast and stable method for navigation aid LED light sources based on array pre-estimation, the method includes the following steps:

[0056] A. Calculate the single light source brightness of the LED light source system according to the FAA and other aviation operation specifications.

[0057] At present, the light source of the runway and taxiway closed sign system usually adopts a single combined light source, and each single light body is composed of multiple LED single light sources connected in series and parallel. Taking the runway closure sign system as an example, suppose the light source structure of the sign system is as follows: the sign system is composed of m groups of light bodies, and each group of light bodies is composed of n LED light sources, and the light source brightness matrix is ​​LD m×n ; The white balance ratio matrix of each color light source is recorded as (W p ) m×n...

Abstract

The invention discloses a fast and stable method for navigation aid LED light sources based on array pre-estimation. The method comprises the following steps: calculating the single light source brightness of the LED light source system according to the FAA and other aviation operation specifications; Introduce the initial pulse drive matrix of the light source system through its own characteristic curve; use the array pre-estimation algorithm to monitor the output matrix quickly and generate the state matrix of the system; adjust the drive matrix of the system, and apply the control amount to the control position to realize the system Fast and stable light source. The invention is fast and efficient, and can significantly improve the reliability of the navigation aid LED light source system, and has very beneficial application effects for aviation safety.

Description

technical field [0001] The invention belongs to the technical fields of computer communication and aviation safety, and in particular relates to a fast and stable method for navigation aid LED light sources based on array pre-estimation. Background technique [0002] The navigation aid lighting system is one of the basic support systems related to the safe and smooth operation of aviation. Due to the safety sensitivity of the industry, the stability and brightness of the navigation aid light source have strict aviation operation specifications of the Federal Aviation Administration, especially for runways and taxiways. The advanced navigation lighting system determines the first and last hurdle of aviation safety, and its importance is self-evident. With the development of energy saving and emission reduction concepts and new light source technology, high-brightness LED light sources are widely used in runway and taxiway closure sign systems. At present, the stability monito...
