Airborne monitoring system based on multilink

Abstract

The invention relates to an airborne monitoring system based on multilink. The system comprises an integrated processing unit, a traffic antenna unit, a GNSS antenna and a satellite antenna unit; thetraffic antenna unit is used for receiving radio frequency signals of the L-wave band induced by an omnidirectional antenna and sending the radio frequency signals to the integrated processing unit; the integrated processing unit is used for monitoring and detecting running state of an integrated processing device, if the equipment is normal, keeping the airborne monitoring system in a silent state, if the equipment is abnormal, outputting monitoring information through satellite links, ADS-B and beidou short messages; the satellite antenna unit is used for receiving and transmitting satellitecommunication signals; the GNSS antenna is used for receiving navigation positioning information of a beidou navigation satellite and the GNSS. According to the airborne monitoring system based on the multilink, monitoring of existing airborne monitoring device is realized, monitoring information of the aircraft will be outputted through multilink when the system is abnormal; functions of the system can be completed just by accessing an emergency power supply, and obtaining and transmitting of aircraft monitoring information without influences due to human error and malicious intrusion can berealized.

Description

technical field [0001] The invention belongs to aviation airborne technology and relates to an airborne monitoring system based on multi-link. Background technique [0002] At present, my country's air transport industry is developing rapidly, and the number of aircraft is increasing rapidly. However, there are relatively large security risks in the surveillance of aircraft, which cannot support the safe and efficient operation of my country's aviation industry. The loss of contact with Malaysia Airlines MH370 in 2014 once again sounded the alarm for aviation surveillance safety. The hidden dangers are mainly manifested in: [0003] (a) Human factors can easily intrude into the aircraft safety assurance system. In the event of communication interruption, data loss, and monitoring obstacles caused by the pilot's manual operation, there is currently no effective means to ensure continuous monitoring of the aircraft; [0004] (b) The global coverage of the current aircraft sur...

Problems solved by technology

[0003] (a) Human factors can easily intrude into the aircraft safety assurance system. In the event of communication interruption, data loss, and monitoring obstacles caused by the pilot's manual operation, there is currently no effective means to ensure continuous monitoring of the aircraft;

[0004] (b) The global coverage of the current aircraft surveillance system based on ground surveillance methods is insufficient, and aircraft surveillance information under a single system structure is easily blocked by external factors
