Embodiment Construction

[0043] The systems, methods and devices of the present invention provide an improved means of enabling communication with a movable object, eg, a self-propelled movable object (eg, an unmanned aerial vehicle (UAV)). In some embodiments, the movable object transmits data to the remote terminal using a plurality of different communication methods. The system, method and device provided by the present invention can adaptively switch between different communication methods according to predefined switching rules to optimize communication speed, delay time, communication bandwidth, signal quality, and / or data transmission range . It should be understood that embodiments of different aspects of the present invention can exist independently, co-exist, or be combined with each other. The various embodiments described herein may be adapted for any of the particular applications mentioned or for any type of movable object.

[0044] For example, the invention can be used on unmanned ae...

Abstract

Systems, method, and devices are provided for transmitting data. In one aspect, a method includes providing a plurality of communication modules, each of the plurality of communication modules configured to transmit data using a different communication method; establishing, with the plurality of communication modules, a plurality of simultaneous respective communication links to a remote terminal; selecting, based on a switching criterion, at least one of the plurality of simultaneous respective communication links to be used to transmit data; and transmitting data via said at least one of the plurality of simultaneous respective communication links selected based on the switching criterion.

Description

Background technique [0001] Unmanned vehicles (Unmanned vehicles, referred to as unmanned vehicles), such as ground vehicles, aerial vehicles, water vessels, underwater vehicles, spaceships, have been widely used in surveillance, search and rescue operations, reconnaissance and Other areas. In some examples, an unmanned vehicle may be equipped with sensors that collect data about the surrounding environment. For example, unmanned aerial vehicles (unmanned aerial vehicles, UAVs) are usually equipped with cameras for aerial photography. [0002] The sensing data collected by the unmanned vehicle can be transmitted to a remote user terminal in real time. However, the current method of transmitting data from unmanned vehicles is not ideal. In some instances, the range of data transfers and other communications with unmanned vehicles is limited by line of sight. Contents of the invention [0003] There is a need for an improved way of being able to communicate with movable ob...
