Problems solved by technology

However, limited by the communication bandwidth from the remote controller to the aircraft, the upgrade firmware takes a long time to transmit, which leads to a slow upgrade process of the aircraft.
[0004] Therefore, the existing aircraft communication system design cannot meet its data transmission requirements

Abstract

The present application discloses an aircraft and an external device thereof, and a communication method, apparatus and system. The method is performed by an aircraft, comprising: receiving a data transmission request; increasing an uplink transmission bandwidth according to the data transmission request; and receiving data to be transmitted from the uplink; wherein the uplink is a communication link to transmit data to the external device from the external device. The above scheme can flexibly adjust the communication bandwidth of the uplink between the aircraft and the external device to meet data transmission requirements.

Description

【Technical field】 [0001] The present application relates to the field of wireless communication, in particular to an aircraft and its external equipment, communication method, device and system. 【Background technique】 [0002] At present, most aircraft such as aerial photography unmanned aerial vehicles communicate with ground equipment such as remote controls to achieve data return and flight control. The two-way bandwidth of the existing communication system composed of the aircraft and the remote controller is generally asymmetrical, and the communication bandwidth from the remote controller to the aircraft is generally much smaller than the communication bandwidth from the aircraft to the remote controller. [0003] When there is a large amount of data communication requirements from the remote control to the aircraft, the broadband design of the existing communication system cannot meet its communication requirements. For example, when using the terminal software to up...
