Targeted staying and return voyage control system of unmanned aerial vehicle

Abstract

The invention discloses a targeted staying and return voyage control system of an unmanned aerial vehicle. The system comprises a GPS positioning module, an electronic compass, a barometer, a memory, and a control chip, and the control chip is connected with the GPS positioning module, the electronic compass, the barometer, and the memory. After the control chip receives coordinate information generated by the GPS positioning module, direction recognition information generated by the electronic compass, and height information generated by the barometer, the information is processed, and a control instruction is generated to control motor driving of the unmanned aerial vehicle so that real-time positioning of any height and position of the unmanned aerial vehicle is realized, and the system is applicable to some special tasks, such as photography and exploration; when the control chip receives a return voyage instruction of a remote controller, the control chip performs comparison treatment according to the position and direction information of the unmanned aerial vehicle fed back in real time and initial coordinate information saved in the memory, and controls the unmanned aerial vehicle to automatically return to the take-off position so that the unmanned aerial vehicle can be rapidly recovered, and the system is more applicable to tasks such as investigation and rescue.

Description

technical field [0001] The invention relates to an unmanned aerial vehicle, in particular to a fixed-point stop and return control system of the unmanned aerial vehicle. Background technique [0002] Most of the existing unmanned aerial vehicles fly through the remote control, and the current unmanned aerial vehicles basically do not have a stable fixed-point stop, can stay in the air, and are also suspended within a certain range. In addition, the existing UAVs basically do not have the function of returning home, and cannot realize one-key returning home. They can only be artificially controlled by the remote control to fly back; Insufficient judgment of the remaining battery power makes it impossible to return the drone to the side in time, which may cause the drone to fall from the sky and be damaged due to the power exhaustion during the flight or return process; The drone will lose the remote control signal, that is, the remote control cannot control the drone, which ...

Problems solved by technology

[0002] Most of the existing drones are flying by remote control, and the current drones basically do not have a stable fixed-point stop, can stay in the air, and can also be suspended within a certain range

In addition, the existing UAVs basically do not have the function of returning home, and cannot realize one-key returning home. They can only be artificially controlled by the remote control to fly back; Insufficient judgment of the remaining battery power makes it impossible to return the drone to the side in time, which may cause the drone to fall from the sky and be damaged due to the power exhaustion during the flight or return process; The human machine will lose the remote control signal, that is, the remote control cannot control the drone, which will cause the drone to fall out of control and be damaged
