A method and system for wireless transmission of airborne flight record data

Abstract

The invention provides an airborne flight record data wireless transmission method and system, and relates to the technical field of communication. The method comprises the steps: receiving data request information transmitted by a ground management center server; transmitting the data request information to an airborne flight recording terminal; receiving the flight record data returned by the airborne flight recording terminal according to the data request information, and carrying out the encryption of the flight record data through a data encryption secret key in the data request information; and transmitting the encrypted flight record data to the ground management center server. The method can reduce the pressure on the ground management center server when the number of airborne flight recording terminals on a parking apron is too large, enables the ground management center server and the airborne flight recording terminal to timely obtain the opposite response, can save the bandwidth, and reduce the data transmission cost.

Description

technical field [0001] The invention belongs to the field of communication technology, in particular to a method and system for wireless transmission of airborne flight record data. Background technique [0002] With the rapid development of aviation technology, the amount of civil aviation aircraft transportation tasks is increasing, the attendance rate of aircraft is getting higher and higher, and the risk of aircraft accidents is also increasing. The data of aircraft flight record system can be used to analyze aircraft aviation accidents The investigation provides an effective basis. At present, most civil aviation airborne flight record data is obtained by the maintenance staff carrying portable ground equipment to the apron, connecting the airborne flight recording system equipment with cables to download data from the aircraft, or directly transferring the data from the airborne flight recording system to disk / The memory card is removed to obtain data. 3G network UM...
