Problems solved by technology

Because the frequency of TCAS inquiry signals is as high as tens of times per second, that is to say, these methods take too long for the outlier elimination of TCAS communication data once, and once adopted, it will greatly increase the burden on the processor

Embodiment Construction

[0017] 1) Outliers and elimination methods of altitude data

[0018] In the original TCAS and S-mode transponder systems, there are four altitude sources for the S-mode transponder, namely ARINC 429 barometric altitude, ARINC 575 barometric altitude, synchronizer altimeter and Gray code altimeter; there are two altitude sources for the TCAS system , Namely ARINC 429 radio altitude and ARINC 552 radio altitude, and each altitude information contains two sets of the same equipment. TCAS and S mode transponder each have a height selection switch.

[0019] After the integration of TCAS and S-mode transponder, S-mode transponder is a sub-module of TCAS, and most of its interfaces are still retained, but the ARINC 575 bus interface is removed. Similarly, the TCAS height source, we discarded the original AIRNC 552 bus interface. In this way, the high source of the entire integrated system is like a mistake! The reference source was not found. Shown.

[0020] Among them, there are four ...

Abstract

The invention relates to a method for rejecting wild values of received data in a traffic collision avoidance system (TCAS). By the method, the wild values of the received height data and the received distance data are avoided and rejected quickly; and the wild values exist in the received data of the TCAS and the working speed of the system is high, so the wild values must be rejected quickly. The invention provides a method for avoiding and rejecting the wild values of the height data and the distance data. By the method, the interference problem of the wild values of the data is solved; the effectiveness of the received data and the flight safety are guaranteed; the input of the wild values is reduced by simplifying the height source of the TCAS; and the wild values of the height and the distance are further rejected by a corresponding software processing method.

Description

(1) Technical field: [0001] The invention relates to a method for rejecting outliers of signals received by a new generation of airborne TCAS anti-collision system. (2) Background technology: [0002] The collision avoidance system on the aircraft, the American aviation system is called the air traffic early warning and collision avoidance system (hereinafter referred to as TCAS), the European aviation system is called the airborne collision avoidance system, the meaning and function of the two are the same, and the composition is also basic Similar, therefore, the description of the present application is described with TCAS as the technical background. [0003] After years of development, the TCAS system has developed a variety of models, such as: TCAS I, TCAS II, TCAS III, TCASIV. Among them, TCAS II is currently the most widely used. It can provide pilots with different colors and shapes to display the relative altitude, distance, azimuth, ascent / descent status and other infor...
