Unmanned aerial vehicle flight state indicating device and indicating method thereof

Abstract

The invention provides a flight state indicating device for an unmanned aerial vehicle. The flight state indicating device comprises a lighting system, a sensor system and a control system which are installed at the bottom of the unmanned aerial vehicle. The control system sends an instruction of reading flight data of the unmanned aerial vehicle to the sensor system according to an instruction of a ground operator; the sensor system is used for reading flight data of the unmanned aerial vehicle and sending the flight data to the control system; the control system is used for converting the flight data into mapping data and sending a light display instruction to the light system according to the mapping data. The lighting system is used for changing the lighting state to display the mapping data. According to the invention, the number is represented by adopting a quinary method through an alternate display mode of the red and green indicating lamps, so that a ground operator can directly know the flight data of the unmanned aerial vehicle, the flight risk is reduced, and the possibility of observation errors of the ground operator is reduced to the greatest extent.

Description

technical field [0001] The present invention relates to the field of aviation technology, in particular to a drone flight state indicating device and an indicating method thereof. Background technique [0002] With the continuous development of UAV control technology, the application field of UAV has involved various fields of military and civilian use, and the safe control of UAV has become a key issue. When the height of the drone is not high, the operator can judge the height of the drone through reference objects such as trees, but when the drone reaches a certain height and there is no reference object, the distance can only be measured visually. The accuracy of visual distance is not high, especially when flying at night, it is more difficult and the error is larger. In addition, for drones, the motor speed, motor voltage and remaining power cannot be obtained through visual inspection, and these physical quantities are important parameters that affect flight safety. ...
