Multifunctional data conversion system based on airborne collision avoidance system

Abstract

The invention discloses a multifunctional data conversion system based on an airborne collision avoidance system, comprising an atmosphere height conversion unit, a radio height conversion unit, and a flight parameter conversion unit. An aircraft atmosphere data machine and an aircraft radio altimeter are respectively connected with the input ends of the atmosphere height conversion unit and the radio height conversion unit. The flight parameter output end of the airborne collision avoidance system is connected with aircraft flight parameter equipment. The multifunctional data conversion system is easy to implement in engineering, and can complete atmosphere height, radio height and flight parameter signal format conversion between the aircraft equipment and the collision avoidance system according to the requirement of an aircraft platform. An adopted sampling circuit reduces the sampling error of analog data conversion and improves the sampling precision of an analog data conversion system. The function of conversion between RS422 data and ARINC429 data and conversion between high-speed ARINC429 data and low-speed ARINC429 data is added.

Description

technical field [0001] The invention relates to the field of airborne anti-collision technology, in particular to a multifunctional data conversion system based on the airborne anti-collision system. 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 decisive warning based on the degree of threat, provide warning information to the pilot in the form of voice, and display the warning information on the traffic / decision display ...
