The embodiment of the present invention provides a data transmission method, device and system, the method includes: controlling the first data receiving device in the open state to receive and send the data transmission signal generated by the drone to the control device; The transmission stability information between the second data receiving devices in the closed state meets the device opening conditions, then the second data receiving device is controlled to receive the data transmission signal, and the first data receiving device is controlled to continue to send the data transmission signal; if the UAV and the second The transmission stability information between a data receiving device satisfies the device shutdown condition, then the second data receiving device is controlled to receive and send the data transmission signal to the control device, and the first data receiving device is controlled to stop receiving the data transmission signal. It can be seen that from the time when the second data receiving device is turned on to when the first data receiving device is turned off, the data transmission link between the control device and the data transmission device is always kept connected, thereby avoiding data loss.
Description
technical field [0001] The invention relates to the technical field of data transmission, in particular to a device switching method and a data transmission system. Background technique [0002] In recent years, drones with the advantages of simple structure, high safety, and low cost of use have been widely used in various industries, especially in areas that require monitoring and inspection, such as high-speed, electric power, and oil pipelines. [0003] Taking the field of oil pipeline inspection as an example, since the laid oil pipeline line is usually relatively long, it is not realistic to use manual inspection. In this case, UAVs are usually used to take all-round and multi-angle shots of the oil pipeline. Then, the UAV sends the captured image data to the corresponding base station in the base station group. Furthermore, the control center will obtain and analyze the image data sent to the base station, so as to complete the inspection of the oil pipeline. [00...
