Description
Technical field
The utility model relates to nolo flight system, particularly a kind of can be at the unmanned plane of disturbance in judgement thing distance at night.
Background technology
Unmanned plane is a kind of unmanned vehicle of being handled by radio robot or self presetting apparatus, be widely used in military affairs, scientific research and sphere of life, can substitute ground traffic tools at disaster fields such as fire, earthquakes, the arrival severe place of environment observes conditions and rescues, also can, carrying out data acquisition and exploration aspect meteorology, space flight, also can be used on the aspects such as nuclear radiation detection, aeroplane photography, mineral exploration aviation, traffic patrolling, security monitoring.
Unmanned plane is generally operated the flight path of unmanned plane awing by operator.But because unmanned plane is in low-latitude flying, can be through a lot of buildingss and bridge etc., operator can be difficult to the practical flight situation of accurate surveying unmanned plane on ground, easily bump against barrier, especially when flying night, due to the impact of surround lighting, depend naked eyes alone and see the flight condition that is difficult to see unmanned plane, so be also difficult to the actual range of judgement unmanned plane and barrier, make in time decisions such as turning to deceleration.
Utility model content
In order to solve unmanned plane, in night flight, cannot correctly judge the problem with obstacle distance, the utility model provide a kind of can be at the unmanned plane of disturbance in judgement thing distance at night.
The technical solution of the utility model is as follows:
Can, at a unmanned plane for disturbance in judgement thing distance at night, comprise unmanned plane main body, light source, CCD camera, control module and side-marker lamp; Described light source and CCD camera have many groups, the adjacent lateral wall that is arranged on unmanned plane main body surrounding respectively, the light transmit direction of the taking lens alignment light source of described CCD camera; Described CCD camera is connected with control module, and described side-marker lamp is arranged on the edge of unmanned plane main body surrounding.
Its further technical scheme is: described unmanned plane main body is many rotor wing unmanned aerial vehicles or depopulated helicopter.
Its further technical scheme is: described light source is LASER Light Source or spotlight.
Useful technique effect of the present utility model is:
The utility model provide a kind of can be at the unmanned plane of disturbance in judgement thing distance at night, only need to laser beam emitting device be installed in common unmanned plane outside, just can realize unmanned plane and in night flying process, automatically measure the function with the distance of barrier, send in time signal, make unmanned plane operator change in time unmanned plane course line, dodge barrier.Make with the naked eye also can easily judge the distance of unmanned plane and barrier.Because technology used is proven technique, so functional reliability is high, realize simple, cheap.Unmanned plane often need to carry out low-latitude flying at night in using, and passes through the barrier such as house, wall in city, and the utility model has solved very large practical problems, has very high using value.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
Fig. 2 is vertical view of the present utility model.
Fig. 3 is the hot spot schematic diagram that the utility model is manually dodged.
Embodiment
Fig. 1 is schematic diagram of the present utility model, adjacent multiple sets of light sources 2 and the CCD camera 3 of being provided with outside unmanned plane main body 1 surrounding.Light source 2 can be LASER Light Source and spotlight.In the present embodiment, light source 2 is LASER Light Source.Side-marker lamp 5 is arranged on the edge of unmanned plane main body 1 surrounding.Fig. 2 is vertical view of the present utility model.In the present embodiment, the surrounding of unmanned plane main body 1 outside is provided with 8 groups of light sources 2 and CCD camera 3, every two adjacent groups interval 45 degree; And 8 side-marker lamps 5 are installed, interval 45 degree between every adjacent two side-marker lamps, during work, every two side-marker lamps that are mutually 180 degree are one group, jointly indicate the width of unmanned plane.
Unmanned plane is in flight course, and light source 2 constantly externally sends laser.Because unmanned plane main body 1 surrounding is equipped with light source 2, therefore any direction of unmanned plane main body 1 has barrier, laser beam can be beaten on barrier, form a plurality of hot spots, the distance dependent of spot size and unmanned plane and barrier, be located at the spot radius ω (z) apart from light source z place, relation is as follows:
ω(z)＝ω
0(1+(λz/πw
0 2)
2)
1/2
Above formula is the common practise of laser physics, can in relevant textbook and resources material, find, wherein, z be light source to the distance of barrier, the radius that ω (z) is laser facula, all the other parameters are the fixed value relevant with LASER Light Source itself.Can from above formula, find out, spot radius ω (z) and light source become positively related relation to the distance z of barrier, and distance is nearer, and the radius of laser facula is less, and distance is far away, and the radius of laser facula is larger.Around this principle, can be incident upon by generating laser the distance of spot size on barrier judgement unmanned plane and barrier.
One, manually dodge
Unmanned plane operator should preset a warning distance L with barrier in advance, this warning apart from time, light source 2 width W of formed hot spot on barrier is adjusted to side-marker lamp 5 formed unmanned plane profile width W on barrier and is equated.When real flying, when light source 2 beats laser beam that (on high building exterior wall) forms hot spot on barrier, side-marker lamp also irradiates the width of unmanned plane body on barrier.Now operator can be by visual inspection, as long as while finding have any one radius to be greater than side-marker lamp radius in a plurality of hot spots, illustrate that unmanned plane is excessively near apart from barrier, needs rerouting, dodges.
As shown in Figure 3, one group of light source 2 in unmanned plane main body 1 and CCD camera 3 are over against barrier 8, be one group with two side-marker lamps 5 of 3 one-tenth 90 degree of this group light source 2 and CCD camera, jointly on barrier 8, form a pair of width hot spot 7, the distance between a pair of width hot spot 7 is the width W of unmanned plane.Other light sources 2 also forms 6 dozens of hot spots on barrier 8 or other barriers of surrounding, if now operator finds that the radius of any one hot spot 6 is greater than W, illustrates that unmanned plane is excessively near apart from barrier, needs rerouting, dodges.
Two, automatically dodge
In the time of light source 2 constantly outside Emission Lasers light beam, the camera lens of CCD camera 3, towards the direction of Ear Mucosa Treated by He Ne Laser Irradiation, is constantly taken pictures.CCD camera 3 can be converted into digital signal optical image, is transferred to control module 4, and control module 4 has comprised the radio operating system of unmanned plane, the digital signal receiving can be sent to unmanned plane operator.In unmanned plane operator's workstation, should store in advance the data such as spot radius as a comparison, when operator finds that spot radius that CCD camera 3 photographs is greater than spot radius as a comparison, illustrate that unmanned plane is excessively near apart from barrier, need rerouting, dodge.The frequency of taking pictures of CCD camera 3 is relevant with the flying speed of unmanned plane, and when unmanned plane during flying speed is fast, the frequency of taking pictures is wanted corresponding raising, avoids unmanned plane to barrier, not make a response in time and to clash into.
Above-described is only preferred implementation of the present utility model, and the utility model is not limited to above embodiment.Be appreciated that the oher improvements and changes that those skilled in the art directly derive or associate under the prerequisite that does not depart from spirit of the present utility model and design, within all should thinking and being included in protection domain of the present utility model.
