Unmanned aerial vehicle system, and communication method and remote control device therefor

A communication method for a UAV system including a first remote control device, a second remote control device, a UAV, and a functional device mounted on the UAV, comprising:

• establishing a first communication connection between the first remote control device and the UAV, establishing a second communication connection between the second remote control device and the functional device, and establishing a third communication connection between the first remote control device and the second remote control device;
• sending, by the first remote control device, remote control information via the first communication connection to control the UAV;
• sending, by the second remote control device, remote control information via the second communication connection to control the functional device;
• and
• sending and receiving, by the first remote control device, interactive data to and from the second remote control device, wherein the interactive data includes at least one type of text data or video data.

A remote control device for a UAV system, comprising a data acquisition unit, a data processing unit, a communication unit, and an output unit, wherein:

• the remote control device communicates with another remote control device through the communication unit;
• the data acquisition unit is configured to collect interactive data, the interactive data including at least one type of text data or video data, the data processing unit is configured to perform packet processing on the interactive data collected by the data acquisition unit, and the communication unit is configured to send the interactive data, packet-processed by the data processing unit, to the another remote control device;
• and
• the communication unit is further configured to receive interactive data sent by the another remote control device, the data processing unit is further configured to parse the interactive data received by the communication unit, and the output unit is configured to output the interactive data parsed by the data processing unit.
