Aircraft and ground station data transmission method based on multiple wireless network cards

The invention discloses an aircraft and ground station data transmission method based on multiple wireless network cards, and mainly solves the problems in the prior art that reliable and efficient data transmission between the aircraft and the ground station cannot be met. The implementation scheme comprises the steps that 1. multiple wireless network cards of airborne data transmission equipmentare accessed to the airport network so as to establish multiple wireless link connection; 2. state information of all the wireless network cards is periodically detected and acquired; 3. the number nof the available wireless network cards is obtained according to the state information of all the wireless network cards; 4. the airborne data transmission equipment processes the file so as to obtain a task sequence and transmits the data of the task sequence to ground station data receiving equipment through n available wireless network cards in parallel; and 5. the ground station data receiving equipment recombines the
