Description
Technical field
The present invention relates to radio wave applied technical field, and in particular to a kind of radio wave positioning based on fish-eye lens
System, charging and localization method.
Background technology
Fish eye lens is a kind of extreme wide-angle lens, and also referred to as full shot, its visual effect are seen in water similar to fish
Examine the things fish-eye lens application principle on the water surface.Flake mirror is referred to as in camera lens of the engineering upward angle of visibility scope more than 140 degree
Head, also there is the camera lens that visual angle exceedes even up to 270 degree in practice.One of the characteristics of panorama picture of fisheye lens, is to correctly retouch
Picture point of the target point in three-dimensional space on imaging plane is stated, and can accurately establish correspondence, in space
Any point can be mapped to corresponding imaging point on focal plane by fish-eye lens.Traditional fish eye lens is generally used in
Optical imaging field, such as pick-up lens, it is general to use two pieces as a kind of ultra-large vision field, the optical imaging system of large aperture
Or object space ultra-large vision field is compressed to the field range of conventional camera lens requirement as preceding light group by three pieces of negative meniscus lens, so that
Normal image or lines is distorted and is bent, thus obtain the image different from other lens shooting effects.It there is no at present
Fish eye lens is used for the record of indoor positioning and wireless charging technical field.
For in theory, lens antenna can pass through electromagnetic wave, spherical wave or cylinder by point source or line source as a kind of
Ripple is converted to plane wave so as to obtain the antenna of the form of a stroke or a combination of strokes, sector or other shapes wave beam.Pass through suitable design lens surface shape
With refractive index n, the phase velocity of electromagnetic wave is adjusted to obtain the plane wave front on radiating aperture.Lens can use crude media (n>1) make
Into, it is also possible to the artificial dielectrics (n being made of metal mesh or metallic plate etc.>1 or n<1) it is made, is managed according to existing lens antenna
By, when lens face size be much larger than radio wavelength size when, electromagnetic wave can be handled with physioptial mode.I.e.
Ignore the wave characteristic of electromagnetic wave, electromagnetic wave is thought of as the radiation exposure of cluster cluster to minute surface, while Application Optics is managed
Reflected in the formula of refraction to handle the electromagnetic wave by lens.
It is theoretical with reference to both the above, the size of fish-eye lens is made when be far longer than radio wavelength, you can will
Incide fish-eye electromagnetic wave and be envisioned for optical radiation, this is found in the focal plane of fish-eye lens with light refraction theory
The point of arrival of electromagnetic wave.It is covered with reception antenna on focal plane, then this system can receive different azimuth in space and penetrate
Electromagnetic wave, but since any one reception antenna all has area, thus it is one that each reception antenna is corresponding
A Space Angle rather than spatial point, such reception antenna form one-to-one relationship with different orientations in space.
For the problem that the charger interface of Current electronic product is varied, standard differs.Charger is plugging repeatedly
In the case of, it is easy to cause interface to wear, thus the service life of charging interface is as the important of restriction electronic product service life
One of factor.At present, gradually approved that it is with following excellent by people using the mode electron product charging of wireless charging
Point：Fettered from socket and cable, charging is more convenient, it is more convenient to carry；Without charger interface, different brands, different product
Charging interface be able to unification；Wire connector is not required, mobile electronic equipment volume is further reduced；Outside due to equipment
There is no metallic contact or opening on shell, the water proofing property of electronic product can be strengthened.
Wireless charging technology comes from wireless power transmission technology, realizes that the mode of wireless charging is broadly divided into four kinds：Electricity
Magnetic inductive, magnetic field resonance type, field coupling formula, radio waves type.Wherein radio waves type passes through microwave launcher and micro-
Wave receiving device, captures the radio wave energy rebounded from wall, and the straight of stabilization is kept while being adjusted with load
Galvanic electricity pressure realizes wireless charging.Although existing radio waves type wireless charging energy transmission distance is remote, electric energy receiving device position
Put and put flexible, achievable mobile charging etc..But its shortcoming is also quite obvious：That is the energy of transmitting terminal is to all the winds to dissipate
, cause its energy utilization efficiency very low.
At present, with expanding economy, the medium-and-large-sized supermarket in city or shopping center are more and more, in large supermarket or shopping
When center is consumed, the phenomenon that companion wanders away or child loses is frequently encountered.Currently using GPS, the Big Dipper as representative positioning
Airmanship is Macro orientation, can not be applied to indoor equipment and the microcosmic of personnel is accurately positioned.Existing indoor positioning navigation
Technology is the Wi-Fi Hotspot signal that terminal device will receive, and by superposition calculation out position, i.e., is installed in building some
A location equipment as wireless router, enables its signal launched to cover each corner of building.It is existing fixed
Position system needs the diverse location in certain area to place several location equipments as wireless router, space hold
