Airborne collision avoidance and ground proximity warning monitoring system and monitoring method thereof

Abstract

The invention discloses an airborne collision avoidance and ground proximity warning monitoring system which comprises a set of four-channel L band antennas and a system host machine. The system host machine is formed by a data processing module, an RF module, a baseband module, and a power module. The four-channel L band antennas are connected with the RF module through coaxial cables. The RF module is connected with the data processing module through the baseband module. The system host machine obtains aircraft body state information through the connection of an avionics full duplex switched Ethernet (AFDX) or a self-bring interface unit. The system has the advantages that the most reasonable monitoring and alarm information and avoidance advice are provided for a pilot, the working pressure of a pilot is reduced, an man-made error determination is avoided, and the flying safety of an airplane is increased; the reuse of resources is realized, the weight, volume, power consumption and cost of airplane monitoring equipment are reduced, and the reliability and scalability of the equipment are improved.

Description

technical field [0001] The invention belongs to the field of flight warning devices, in particular to an airborne collision avoidance and ground proximity warning monitoring system and a monitoring method. Background technique [0002] Flight accidents caused by air plane collisions and flight collisions with terrain are one of the most important factors affecting the safe flight of civil aircraft today. Traditional civil aircraft are equipped with airborne collision avoidance systems and ground proximity warning systems that can avoid collisions between aircraft and aircraft, between aircraft and terrain or obstacles. [0003] Among them, when the airborne collision avoidance function is working, it automatically sends an inquiry signal compatible with the ground secondary radar to obtain and detect the distance, azimuth, altitude and identification code of the surrounding aircraft, and gives the possible air collision by combining the state information of the aircraft.

Problems solved by technology

The two devices are installed independently, and the system weight, volume, cross-linking cost, and maintenance cost are very high, and the disadvantage of this independent installation method is: in the actual flight environment, once a situation occurs, due to time constraints or limited conditions, each The warning and avoidance information generated at the same time make the pilot unable to understand the cause of the warning in a timely, accurate, intuitive and effective manner, and then operate incorrectly and cause an accident
