In the manual mode of operation, the user must directly control the flight path of the unmanned aerial vehicle 60 at the ground station 61, as well as the information to be displayed by the unmanned aerial vehicle 60. In the automatic mode of operation, the ground station 61 uses the user-preset flight path and the broadcast data to control the flight path of the unmanned aerial vehicle 60 and the information to be broadcast on the path. The display device 620 is electrically connected to the main control circuit MCU through the serial interface bus SPI. When the main control circuit MCU receives the display data through the Zigbee module 611, it transmits the data to the display device 620 through the sequence peripheral interface bus SPI to display the data.

In summary, the spirit of the present invention is that an unmanned aerial vehicle is equipped with a broadcast device to play an advertisement capable of attracting attention and to provide a completely different information broadcast method. In addition, the present invention is coupled with short-range wireless communication technology, enabling unmanned aerial vehicles to play instant regional information and provide more mobile advertising and information dissemination methods.
