Embodiment 1
[0082] Example 1, such as figure 1 As shown, an autonomously navigating UAV system according to an embodiment of the present invention includes: an aircraft platform, a sensor subsystem, an autopilot, a remote controller, and a ground monitoring station.
[0083] The aircraft platform is a quadrotor aircraft. The quadrotor aircraft is equipped with a GPS positioning module. The GPS positioning module receives satellite signals to determine the current latitude and longitude position of the quadrotor aircraft and provide basic data for navigation. Among them, the four-rotor aircraft wing is a four-axis aircraft, and the rotors are symmetrically installed on four axes, and the rotors on the same diagonal form a group, and four small brushless DC motors are symmetrically installed on the four-axis rotors to drive four A rotor spins at high speed. By changing the speed of the brushless DC motor, the flight functions of the aircraft such as forward flight, side flight, climb, and ...
Embodiment 2
[0136] Embodiment 2, a kind of navigation method of the unmanned aerial vehicle system of autonomous navigation, comprises the following steps:
[0137] Step 1, install a GPS positioning module, an inertial measurement unit, a miniature camera, an ultrasonic sensor and a laser scanning radar on the aircraft platform;
[0138] Step 2, the autopilot is connected with the GPS positioning module, the inertial measurement unit, the miniature camera, the ultrasonic sensor and the laser scanning radar through wireless network communication;
[0139] Connect the ground monitoring station and the autopilot through a wireless network;
[0140] Step 3, setting the task of flying the UAV on the ground monitoring station, including the waypoint of the flight and the attitude of the flight action;
[0141] Step 4, the quadrotor aircraft starts to fly according to the task, the GPS positioning module receives the satellite signal, determines the current latitude and longitude position of th...

Abstract
The invention discloses an autonomous navigation unmanned aerial vehicle system which comprises an aircraft platform which is a four-rotor aircraft; a sensor subsystem which comprises an inertia measurement unit installed inside the four-rotor aircraft, a micro camera installed at the bottom of the four-rotor aircraft, an ultrasonic sensor installed at the bottom of the four-rotor aircraft and a laser scanning radar installed at the top of the four-rotor aircraft; an automatic driving instrument which is in communication with the GPS positioning module and the sensor subsystem through a wireless network; a remote controller which is in communication connection with the four-rotor aircraft through the wireless network; a ground monitoring station which is in communication with the automaticdriving instrument through the wireless network. The invention further provides a navigation method of the autonomous navigation unmanned aerial vehicle system. The invention has the beneficial effects that the positioning and navigating are allowed when entering an indoor environment, obstacle avoidance capability is achieved, an optimal route to a target point can be automatically judged, autonomous navigation is realized, and multiple operation modes are provided. The autonomous navigation unmanned aerial vehicle system is convenient, practical, flexible and variable.
Description
technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to an autonomous navigation unmanned aerial vehicle system and a navigation method thereof. Background technique [0002] At present, most micro-aircraft produced in various countries rely on satellites for positioning and navigation, and can only fly according to preset routes, and none of them have the ability to avoid obstacles. This makes MAVs difficult to use in city blocks and alleyways, or easily crashed while in use. At the same time, it also makes the micro air vehicle seem powerless when it is necessary to perform tasks such as reconnaissance or dangerous goods detection inside the building. Contents of the invention [0003] In order to solve the above problems, the purpose of the present invention is to provide an autonomous navigation UAV system and its navigation method, which can avoid obstacles and realize autonomous navigation. [0004] The inve...
