Interface adaptation method and circuit used for airborne collision avoidance system

Abstract

The invention discloses an interface adaptation method and a circuit used for an airborne collision avoidance system, relates to an air collision avoidance technology, and aims to provide a data conversion method and a circuit based on an aerialcarrier platform. The technical note of the circuit provided by the invention is as follows: the circuit comprises an atmosphere height acquiring and coding module, a radio altitude acquiring and coding module, and a fly parameter data conversion module, wherein the atmosphere height acquiring and coding module is used for acquiring current atmosphere height value, and the atmosphere height value is changed into an ARINC 429 data format so as to be finally output to the airborne collision avoidance system; the radio altitude acquiring and coding module is used for acquiring current radio altitude value, and the radio altitude value is changed into the ARINC429 data format so as to be finally output to the airborne collision avoidance system; and the fly parameter data conversion module is used for collecting alarm information generated by the airborne collision avoidance system, the alarm information is subjected to digital-analog conversion so as to be finally output to an airplane reference record instrument. By using the method and the circuit provided by the invention, a compatible problem of the existing airplane and digital airborne collision avoidance system following a Russian-made protocol can be solved.

Description

technical field [0001] The invention relates to mid-air collision avoidance technology, in particular to a data conversion method and circuit based on an aircraft platform. Background technique [0002] The fundamental purpose of the air collision avoidance system is to ensure the safety of the aircraft on the route, and effectively complete the mutual avoidance of the aircraft on the route during the flight. Through the effective tracking and monitoring of aircraft equipped with air traffic control transponders in the nearby airspace, it completes the acquisition and calculation of the distance, speed, flight altitude, azimuth and other information of the target aircraft, and correctly generates traffic warnings according to the target's trajectory, or Further generate a decision warning based on the degree of threat, provide warning information to the pilot by voice, and display the warning information on the traffic / decision display at the same time, remind the pilot to t...

Problems solved by technology

[0003] In the existing technology, especially in China, the air data computers, radio altimeters, aircraft parameter recorders (hereinafter referred to as flight parameter recorders) and other equipment on most aircraft still use the previous Russian-made protocol, which is Analog devices, but the current airborne collision avoidance system is a digital device. When the airborne collision avoidance system is applied to an aircraft that adopts the Russian-made protocol, there will be problems with incompatible data formats and signal levels, and the inability to communicate with each other.
