Embodiment 1

[0044] A mobile base station of the present invention includes a base body, a GPS module arranged on the base body, a base station data transmission station, and a network communication module, and the network communication module is a public network wireless data transmission module, such as a 4G communication module or 5G communication module; or the network communication module is a WIFI module or a wired network.

[0045] Wherein, the base station is a portable frame, such as a frame that is easy to insert into the ground or is fixed relative to the ground. The frame is used to provide a stable and reliable positioning reference, and the flexible arrangement of the mobile base station can be carried out in an area with a good signal. Deployment for easy coverage of the entire work area.

[0046] Recently, it also includes a relay module for wireless data transmission communication with the mobile base station through a private network. The relay module is provided with a w...

Embodiment 2

[0049] The one-station multi-machine system of the present invention includes the mobile base station, a plurality of unmanned aerial vehicles and a background processing center, such as a cloud background;

[0050] Wherein, the UAV is provided with a differential GPS module and an airborne data transmission station communicating with the base station data transmission station;

[0051] The public network wireless data transmission module communicates directly with the background processing center.

[0052] Wherein, the UAV is provided with an on-board mobile public network communication module, and the UAV directly communicates with the background processing center through the on-board mobile public network communication module, such as using The MQTT protocol completes the communication between the UAV and the cloud platform. Based on the heartbeat mechanism of the protocol, the background processing center can know the network status of the mobile public network in the are...

Embodiment 3

[0057] A communication method for a one-station multi-machine system of the present invention comprises the following steps,

[0058] 1) The operation data of the drone is uploaded to the mobile base station through the digital transmission station, and the mobile base station forwards the data to the background processing center; at the same time, when the mobile public network signal meets the transmission conditions, the drone directly communicates with the background processing center to upload the operation data; if the signal status of the mobile public network is not determined, wait for the feedback from the UAV. For example, through the preset mechanism, the UAV needs to automatically upload the flight data to the mobile base station and the background processing center every second. If the background processing center does not If the direct UAV upload information is received, it is considered that the current mobile public network signal of the UAV is not good and can...
