Unmanned aerial vehicle safe landing system and unmanned aerial vehicle with landing system

Abstract

The invention provides an unmanned aerial vehicle safe landing system. The safe landing system comprises a master control module and a laser transmitting device which are arranged on an unmanned aerial vehicle body. The laser transmitting device is connected with the master control module. The master control module is used for sending out a laser transmitting control command to the laser transmitting device when an unmanned aerial vehicle hovers at the upper air near a landing point. The laser transmitting device is used for transmitting a laser beam when receiving the laser transmitting control command and projecting the laser beam to the ground where the landing point is located to form a landing region. The master control module is further used for sending out a landing command and controlling the unmanned aerial vehicle to land in the landing region. By the utilization of the unmanned aerial vehicle safe landing system, the landing region which is formed by the laser beam and can achieve a prompting and warning effect can be projected before the unmanned aerial vehicle is landed so that personnel on the ground can see the landing of the unmanned aerial vehicle and can be reminded to get away from the landing region of the unmanned aerial vehicle, and the situations of the loss of life and personal injury and the loss of the unmanned aerial vehicle are effectively avoided.

Description

technical field [0001] The invention relates to the application field of unmanned aerial vehicles, in particular to a safe landing system for unmanned aerial vehicles and an unmanned aerial vehicle with the landing system. Background technique [0002] At present, the existing automatic return system for drones only relies on GPS and the latitude and longitude of the take-off point recorded by the flight controller to return. The landing process is: the drone returns to the sky above the return point, hovers for a few seconds, and then lands. Therefore, the accuracy of the UAV returning to the home point (that is, the take-off point recorded before the UAV took off) is extremely low, and sometimes it even returns directly above the driver, requiring the driver to constantly adjust the UAV’s air position to Let the drone land safely at the home point or in a safe area. When the UAV goes out of control and returns, the remote controller cannot control the UAV. If the UAV retu...
