Multi-mode encoding method based on integrated monitoring

Abstract

The invention relates to the technical field of airborne collision avoidance systems and discloses a multi-mode encoding method based on integrated monitoring. The method specifically comprises the following steps of: 1, setting an encoding module, wherein the encoding module is used for finishing encoding of different modes according to different trigger signals so as to output encoding pulses, and the encoding module is available for S-mode response triggering, A / C-mode response triggering, A / C / S-mode response triggering and interrupted concussion triggering; and 2, when the encoding module receives an S-mode response trigger signal, starting a timer for counting, and in an allowable time range of a S-mode response delay, allowing trigger signals of other modes to work normally within a specified time range, wherein the threshold of the timer is the time threshold allowed by the S-mode response delay. The delay allowed by the S-mode response is 128[mu]s, and in the delay time, other modes are allowed to work normally, so that the response rate of the S-mode response trigger signal is ensured, and extra hardware equipment is not added.

Description

technical field [0001] The invention relates to the technical field of airborne collision avoidance systems, in particular to a multi-mode encoding method based on comprehensive monitoring. Background technique [0002] The airborne collision avoidance system (ie TCAS-Traffic Alert and Collision Avoidance System) is defined by the Federal Aviation Administration (FAA) and is an essential device to prevent dangerous approach and collision accidents of air planes. TCAS is mainly used to provide air safety separation guarantee for aircraft. The system uses secondary radar to detect approaching aircraft in the nearby airspace. When necessary, it reminds pilots to take evasive measures to maintain an appropriate safe distance from other aircraft to achieve the purpose of collision avoidance. The flight practice in recent years has proved that this system is the last line of defense to prevent aircraft collisions in the air, and it is also one of the most effective means at presen...
