Description
Technical Field
The invention relates to the field of unmanned aerial vehicle control, in particular to an unmanned aerial vehicle counter-braking system based on an electromagnetic induction system, a photoelectric induction system and a GPS induction system.
Background
According to 2016 year data, the domestic unmanned aerial vehicle sales volume is about 39 thousands of unmanned aerial vehicles, and according to IDC prediction of an industry analysis company, the predicted shipment volume of the Chinese market consumer-grade unmanned aerial vehicle in 2019 years reaches 300 thousands of unmanned aerial vehicles, and the unmanned aerial vehicle has a greatly rising trend. Although the civil aviation has been out of the relevant regulations to restrain the unmanned aerial vehicles, in the face of the unmanned aerial vehicles with the quantity and the scale, users who are not trained professionally, are in need of meeting personal interests, are inexperienced and are not aware of law and law consciousness of flight, meanwhile, criminals have appeared to utilize the civil unmanned aerial vehicles to carry out illegal activities and attack of violence and terrorism, the supervision of the unmanned aerial vehicles is difficult to put in place in a short time, and the unmanned aerial vehicles threaten important places such as airports, oil depots, prisons and the like increasingly.
From the type of unmanned aerial vehicle above, according to the flight mode, mainly divide into two kinds, one kind is the unmanned aerial vehicle of fixed wing, and this kind of unmanned aerial vehicle's characteristics are the dead time long, but to the requirement of operator high, need through the training of longer time, just can be skilled and master its flight skill. The other is the unmanned aerial vehicle of rotary wing, and this kind of unmanned aerial vehicle characteristics are the most common motor drive unmanned aerial vehicle, and the dead time is shorter, but controls the degree of difficulty not big, and amateur just can be skilled in mastering the flight skill one or two days.
The first type is an unmanned aerial vehicle produced by a normal manufacturer and sold in a set, such as the most famous unmanned aerial vehicle in Xinjiang, and has the characteristics of stable and reliable flight, small operation difficulty and powerful function; but the flight control strictly complies with some national flight restriction regulations, such as no-fly zone restrictions and the like. The second type is the unmanned aerial vehicle assembled by the model airplane amateur, and along with the release of a plurality of video courses on the network, the amateur can purchase materials on the network and can assemble the materials quickly, and the unmanned aerial vehicle is characterized by simple structure and not very powerful functions; however, the producer may select the remote control and flight control module themselves, and may be able to code modify many open-source flight controls to modify their flight and control patterns.
The control of the unmanned aerial vehicle mainly comprises the control of a manufacturer and the countercontrol of a third party, and the control of the manufacturer mainly comprises the following aspects:
(1) and a no-fly zone code is implanted in the flight control, so that the airplane cannot fly into the no-fly zone or cannot take off in the no-fly zone. The subsequent manufacturers can also temporarily add the function of the no-fly zone remotely.
(2) The outgoing unmanned aerial vehicle is strictly registered, and the purchaser is strictly registered with the real name so as to meet the requirement of the civil aviation central office.
(3) And a subsequent unmanned aerial vehicle manufacturer can also establish a cloud platform database to control the positions and states of all the selling unmanned aerial vehicles.
The third party's countermeasures force the drone to runaway or land, mainly within the regulatory domain. The main means include detection, discovery, localization, tracking, interference, decoy, and traceability. The characteristics of the existing reaction system mainly comprise the following aspects:
(1) in the detection discovery means, radar positioning detection is mainly used;
(2) in a counter measure, flight control signals, GPS signal suppression and navigation deception are mainly used;
(3) in evidence collection and tracking, the recording of an optoelectronic system is taken as the main point.
From the current research situation at home and abroad, the products at the present stage have the following advantages and disadvantages:
in the detection and discovery means, the radar can complete searching, detecting and tracking various targets by actively transmitting microwaves to detect the moving targets. The system has the advantages that the system can monitor all-weather, has a long action distance, and can detect and track multiple targets simultaneously; the disadvantage is that the erection environment is high in requirement and is not suitable for the situation with barrier.
In the evidence obtaining means, the photoelectricity can well cooperate with the microwave radar to track and classify the targets. The method has the advantages that visual and high-precision target information can be provided; the defect is that the detection distance is relatively short and is easily interfered by factors such as weather, building shielding and the like.
In the countermeasures, the navigation signal deception has a good effect on the unmanned aerial vehicle of the regular manufacturer, but will fail to the unmanned aerial vehicle that has been reformed or the assembled unmanned aerial vehicle that does not rely on the navigation positioning system. The suppression interference on the remote controller is full-band suppression, and the interference on other systems is also large.
