Abstract

The invention provides a large passenger aircraft cabin and information system with wireless broadband. The system comprises a cabin core system, a ground communication base station and a ground data center, wherein the ground communication base station is matched with the ground data center. Information of the cabin core system can be wirelessly transmitted to the ground data center, individual needs of passengers are met, updated content of a ground electronic flight bag can be wirelessly uploaded to an on-board electronic flight bag, aircraft state data and maintenance data of an on-board maintenance system can be transmitted to the ground data center, ground maintainers can conveniently monitor the flight state of an aircraft in real time, running safety of the aircraft is guaranteed, the maintenance efficiency of an aircraft maintenance department is improved, and safety, economy and comfort of domestic civil aircrafts are improved.

Description

technical field [0001] The invention relates to the technical field of wireless broadband communication applications, in particular to a wireless broadband communication system for large passenger aircraft. The system can realize the wireless connection between the airborne system and the ground system. Background technique [0002] In recent years, with the rapid development of civil aviation and the continuous increase of flight traffic, the requirements for aviation control departments and airline operation control and engineering maintenance departments are getting higher and higher, and the corresponding requirements for control methods are also getting higher and higher, mainly reflected in The communication quality of the air-ground data link, the expansion of communication coverage and the stability and reliability of the communication system are improved. The ground-air command communication of the air traffic control department is mainly based on VHF ground-air vo...
