Description
Technical field
The present invention relates to a kind of unmanned plane landing methods, more particularly to unmanned plane landing guidance system.
Background technique
Unmanned plane using more and more extensive, brings great convenience to production, the life of people in social every profession and trade
Meanwhile the accuracy and reliability of manual control unmanned plane landing is not high, especially in environmental condition complexity, guides unmanned plane
Accurate landing difficulty is very big, is unfavorable for the application of unmanned plane.
Summary of the invention
The purpose of the present invention is in view of the above technical problems, and a kind of unmanned plane designed lands guidance system, for nobody
Machine provides the control method of landing guidance, in the case where not by manual operation, accurately safely realizes that unmanned plane is automatically fixed
Point landing simplifies unmanned plane landing control technology, expands unmanned plane and uses model under special applications condition and complex environment
It encloses.
In order to achieve the above object, the present invention uses following technical scheme.
A kind of unmanned plane landing guidance system, including following part: laser aiming sender unit, laser aiming signal
Reception device, the laser aiming sender unit are mounted on the predetermined level point position of unmanned plane, emit high frequency to unmanned plane
The laser aiming signal of variation；Laser aiming signal receiving device is mounted on unmanned plane, is believed by the laser of multiple matrix arrangements
Number receiver composition judges unmanned plane and drops by calculating the situation of change of each received laser signal of laser signal receivers
The distance of drop point and relative position, guidance unmanned plane landing.
Unmanned plane works as satellite within the scope of several meters of predetermined landing place by satellite or wireless signal positioning method
Or wireless signal positioning accuracy is unable to satisfy unmanned plane landing when requiring, laser aiming sender unit starting, from predetermined drop
The laser aiming signal that drop point site changes to surrounding transmitting high frequency, according to landing situation by preset program control laser aiming letter
Number variation and emitting area, according to unmanned plane receive feedback gradually reduce laser aiming signal transmitting range.
The laser aiming signal that laser aiming sender unit is emitted is in a certain angle, when matrix arrangement on unmanned plane
Laser aiming signal receiving device in unlike signal receiver receive guidance signal after, pass through calculating matrix arrange difference
The distance and angle of signal receiver received signal compare received laser signal and draw with the laser obtained by wireless signal
Signal intensity rule when sender unit transmitting is led, judges unmanned plane at a distance from laser aiming sender unit and phase
To position, unmanned plane landing is guided.
It keeps wireless signal to connect between landing guide device in unmanned plane landing bootup process, is obtained by wireless signal
Signal intensity rule when laser aiming sender unit emits, is received with laser aiming signal receiving device on unmanned plane
Laser signal comparison, the calculation basis accurately judged as distance between unmanned plane and level point and relative position.
Due to using technical solution as above, the present invention has the advantages that and feature.
1, the control method of landing guidance is provided for unmanned plane, in the case where not by manual operation, accurately safely
It realizes the landing of unmanned plane automatic pointing, simplifies unmanned plane and land control technology, expand unmanned plane in special applications condition and multiple
Operation strategies under heterocycle border.
2, unmanned plane landing guidance system uses laser aiming signal, and accuracy height, strong antijamming capability compensate for satellite
Or the deficiency of wireless signal positioning accuracy.
3, unmanned plane landing guidance system combination laser signal and wireless signal control, and can be believed at any time according to laser aiming
The transmitting of the feedback adjustment laser aiming signal of number reception device, flexibility height are applied widely.
Detailed description of the invention
Fig. 1 is unmanned plane of the present invention landing guidance systematic difference schematic diagram.
Fig. 2 is that unmanned plane of the present invention landing guidance system laser guides the signal of signal receiving device to receive schematic diagram.
Specific embodiment
In order to realize the present invention technological means, feature, reach purpose and effect is easy to understand, below with reference to one
The diagram of kind embodiment, the present invention is further explained.
As shown in Figure 1, unmanned plane landing guidance systematic difference, unmanned plane 1, rotor 2, laser aiming signal receiving device
5, undercarriage 6, laser aiming sender unit 8, laser beam emitting head 7, laser signal 3,4, laser aiming sender unit 8
Emit laser aiming signal 3,4 by laser beam emitting head 7, the laser aiming signal receiving device 5 on unmanned plane 1 receives guidance letter
After numbers 3,4, judge that unmanned plane 1, with relative position, guides unmanned plane 1 to land at a distance from laser aiming sender unit 8.
As shown in Fig. 2 left figure, laser aiming signal receiving device 1, by 2 groups of laser signal receivers of multiple matrix arrangements
At, by calculate the received laser signal 3,4,5 of each laser signal receivers 2 distance and angle change situation, comparison pass through
Situation of change when the laser aiming signal 3,4,5 that wireless signal connection obtains emits judges that unmanned plane and laser aiming signal are sent out
The distance of injection device and relative position.Fig. 2 left figure is respectively illustrated with right figure, and unmanned plane is located at different positions above predetermined level point
When setting, the difference of 1 the received laser signal 3,4,5 and 6,7,8,9 of each laser signal receivers 2 of laser aiming signal receiving device
It is different, the position of unmanned plane is judged by calculating the difference of these signals, guides the accurate landing of unmanned plane.
The basic principles, main features and advantages of the present invention have been shown and described above.The technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and the above embodiments and description only describe this
The principle of invention, various changes and improvements may be made to the invention without departing from the spirit and scope of the present invention, these changes
Change and improvement all fall within the protetion scope of the claimed invention.The claimed scope of the invention by appended claims and its
Equivalent defines.
