Abstract

The invention discloses an asynchronous parallel detection method for aviation navigation aid facility faults. The asynchronous parallel detection method comprises the following steps: constructing anavigation aid facility state matrix; calculating all characteristic values and corresponding characteristic vectors of the state matrix rapidly in an asynchronous parallel mode, and achieving comprehensive detection and positioning; carrying out feature extraction on the state matrix through optimal orthogonal transformation; and adopting a principal component analysis method to realize top-speeddetection under the maximum characteristic state of the aid-to-navigation facility. According to the invention, all-weather online real-time fault detection of all electrical equipment in an aircraftactivity area can be realized; comprehensive and top-speed working modes are provided, real-time detection of component-level faults of the aid-to-navigation facilities is achieved by quickly judgingmain components of the state matrix, a large amount of manual troubleshooting time can be saved, quick recovery of airport functions after faults occur is achieved, aviation safety is powerfully maintained, and the method is good in real-time performance, high in speed and high in efficiency.

Description

technical field [0001] The invention relates to an asynchronous parallel detection method for faults of aviation navigation aids, and belongs to the fields of aviation safety, computer and communication. Background technique [0002] The aircraft activity area is the core functional area of ​​the airport, and it is also a key guarantee area related to aviation safety. The fault detection technology of its navigation aids, especially the rapid fault detection and positioning technology directly affects the safety and efficiency of aviation operations. In the military field, this technology determines the recovery efficiency of airport functions after disasters. However, the current fault detection and location technology still needs to rely heavily on manual work, and can only realize system-level detection, but cannot complete rapid detection and rapid location of component-level faults. Contents of the invention [0003] In order to solve the above-mentioned problems, th...
