Abstract

The embodiment of the invention provides a device switching method, a device switching device and a data transmission system. The method comprises the steps of: obtaining first transmission stabilityinformation among a data transmitter and multiple data receivers in the on state respectively and second transmission stability information among the data transmitter and data receivers in the off state; and, in the multiple data receivers in the on state, if the first transmission stability information corresponding to any data receiver satisfies a switching condition, controlling any data receiver to be switched to the off state, controlling the target data receiver determined according to the second transmission stability information to be switched to the on state, and controlling the remaining data receivers in the on state to be kept same. In the time period from turnoff of any data receiver to turn-on of the target data receiver, the remaining data receivers for normally receiving data transmission signals exist; the fact that a data transmission link is always connected can be ensured; and data loss due to disconnection of the transmission link is avoided.

Description

technical field [0001] The present invention relates to the technical field of data transmission, and in particular, to a device switching method, device and data transmission system. Background technique [0002] In recent years, UAVs with the advantages of simple structure, high safety and low cost of use have been widely used in all walks of life, such as military reconnaissance, geological survey, film and television shooting and so on. [0003] Taking the field of geological survey as an example, in the prior art, geologists are required to conduct surveys in the target area on the spot. However, the target area is often complicated in geological state and has many uncertain factors, so it is easy to produce emergencies and even cause casualties. In this case, the drone can be used to shoot all-round and multi-angle shooting of the target area. Then, the data transmitter configured by the drone itself is used to transmit the captured image data to the corresponding ba...
