Auditory warning method of air collision avoidance system and device of auditory warning method

Abstract

The invention discloses an auditory warning method of an air collision avoidance system and a device of the auditory warning method, and aims at providing an auditory warning method which can reduce the dependence on visual warning and reduce the probability of heading down operation, and is high in response efficiency. The method is realized through the following technical scheme: generating a corresponding warning rule according to a warning request sent by the air collision avoidance system, so as to constitute auditory warning data; obtaining a front tone guiding warning sound source and voice warning sound source data through the warning rule; converting speed change demand sent by the air collision avoidance system into space angle information according to certain rule; realizing space three-dimensional stresses of the front tone guiding warning sound source by utilizing a three-dimensional audio engine according to the space angle information formed by converting, so as to reflect a speed demand; realizing space three-dimensional stresses of a voice source according to dangerous article orientation information sent by the air collision avoidance system, so as to reflect threat orientation information; then splicing front tone guiding and voice warning sequentially according to the warning rule, so as to constitute output warning tone, and to accomplish one auditory warning.

Description

technical field [0001] The invention relates to an audible warning technology of an air collision avoidance system, in particular to a method and device for realizing an audible warning of an air collision avoidance system with space situation information through three-dimensional audio technology. Background technique [0002] With the rapid development of the aviation industry and the increasing air traffic density, it is necessary to provide pilots with a reliable and maneuverable anti-collision measure on the basis of the traditional air traffic control (Air Traffic Control, ATC) system to improve the safety of air traffic sex. The Traffic Collision Avoidance System (TCAS) is a set of computer systems installed in medium and large aircraft to avoid collisions between aircraft in the air. It is mainly composed of transponder, transceiver, air collision avoidance warning computer, warning display device and so on. The monitoring range is generally 30 nautical miles in fr...

Problems solved by technology

[0006] 1) The auditory warning in the TA phase is only used as a reminder and does not contain additional information. If information on threats needs to be obtained, it must be obtained through visual warnings, which increases the operational burden of the pilot to a certain extent. At the same time, frequent Head-down operation is one of the main causes of flight accidents;

[0007] 2) In the RA stage, although the auditory alarm gives an indicative opinion, it is necessary to understand the audio signal. In the case of an emergency and effective response time, especially when the "climbing" and "descent" operations repeatedly appear alternately When it is used, it is prone to short-term reaction barriers, resulting in wrong operation and accidents.
