The invention discloses a method for controlling mounting of an unmanned aerial vehicle by a ground station. Connection is established through a ground station and flight control of the unmanned aerial vehicle. the flight controller is connected with the holder; When a task is different, the ground station and the holder perform information transparent transmission through flight control to control different mounting; wherein the information unvarnished transmission comprises control information uploading and data information downloading; a communication link between a ground station and a mounting holder is established through flight control; the function of controlling the mounting equipment can be completed through the ground station without modifying flight control software, the communication bandwidth of the flight control is amplified without modifying hardware, the communication pressure is not increased, communication is carried out between the unmanned aerial vehicle ground station and the holder through flight control unvarnished transmission, and the holder controls the corresponding unmanned aerial vehicle mounting equipment.
