Abstract
The invention discloses a novel photon receiving end, which comprises a case and a photodiode arranged in the case, wherein a part of the inner surface of the case right aligned with the photodiode is a planoconvex lens, the outer surface of the case is a plane, and parts of the outer surface of the case and the inner surface of the case right aligned with the photodiode are made of transparent materials. The novel photon receiving end has the advantages that the case of a photon client adopts the planoconvex lens type light gathering design, and the gathering effect is realized on light beams, so more visible light can be gathered onto the receiving surface of the photodiode, the sensitivity of the photodiode is improved, the receiving performance of the photon receiving end is enhanced, and good development prospects are realized.
Description
Technical field
The present invention relates to photon gate control system field, relate to a kind of novel photon receiving end particularly.
Background technology
Gate control system is exactly the system that exit and entrance is carried out control, and it is development and come on traditional door lock basis.Traditional mechanical door lock only is simple mechanical hook-up, and no matter how reasonable structural design is, and how firm material is, and people can open it through various means.Pretty troublesome at a lot of passage of discrepancy personnel (office block, hotel guest room) key management, key loss or personnel change and will change lock & key together.For addressing these problems, the electronics magnetic card lock has just appearred, electronic password lock, the problem of electronics magnetic card lock is that information is replicated easily, and it is big to wear and tear between card and the card-reading machine, and failure rate is high, and safety coefficient is low; The problem of electronic password lock is that password is revealed easily, has no way of again having looked into, and safety coefficient is very low.Simultaneously, the product in this period is installed in outdoors owing to adopting Card Reader part (password input) and control section to lump together mostly, is easy to by the people at the outdoor lock of opening.In recent years along with contactless card is technological, the development of biological identification technology; The system that various technology such as induction cassette gate control system, fingerprint entrance guard system occurred; But induction cassette gate control system complex operation; Shortcomings such as fingerprint entrance guard system has fingerprint and is prone to be stolen, and client is prone to be damaged, and discrimination is low.
For addressing the above problem, the photon gate control system is arisen at the historic moment, and the photon gate control system generally includes photon key and photon door lock; The photon key is used to launch the light signal that contains unlocking cipher information, and the photon door lock is the photon receiving end, light signal is resolved after receiving light signal; If light signal contains unlocking cipher; Then control door lock and open, otherwise, then close.The project organization of whole photon receiving end has on-dismountable property.Photodiode in the photon receiving end needs the shell protection, but no matter selects the shell of which kind of material for use, all can cause decay to the visible light signal that receives, and influences the sensitivity of photon receiving end.
Summary of the invention
The technical matters that the present invention solves is, a kind of novel photon receiving end is provided, and the shell of this photon receiving end is the design of plano-convex lens formula optically focused, has strengthened the sensitivity of photodiode, has improved the receptivity of photon receiving end.
The technical solution adopted for the present invention to solve the technical problems is: the present invention provides a kind of novel photon receiving end; Comprise shell and place the photodiode in the shell; Inner surface of outer cover and photodiode are plano-convex lens over against part; Outer surface of outer cover is the plane, and outer surface of outer cover and inner surface of outer cover and photodiode are transparent material over against part.
Preferably, photodiode is at the focal length place of plano-convex lens.
Preferably, transparent material is polymethylmethacrylate, polystyrene, glass, polycarbonate, poly(4-methyl-1-pentene).
Preferably, also comprise pilot lamp and hummer.
Preferably, the visible light signal that comprises unlocking cipher that photodiode will receive converts electric signal into.
Beneficial effect of the present invention is; The shell of photon client of the present invention is the design of plano-convex lens formula optically focused, and light beam is converged effect, makes more visible lights can converge to the receiving plane place of photodiode; Strengthen the sensitivity of photodiode, improved the receptivity of photon receiving end.
Description of drawings
Fig. 1, the novel photon receiving end of the present invention structural representation;
Fig. 2, the plano-convex lens principle schematic;
Among the figure, 1 outer surface of outer cover, 2 inner surface of outer cover, 3 photodiodes, 4 pilot lamp, 5 hummers.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the present invention is done further description:
Fig. 1 shows the novel photon receiving end of the present invention structural representation; Comprise shell and place the photodiode 3 in the shell; Inner surface of outer cover 2 is plano-convex lens with photodiode over against part; Outer surface of outer cover 1 is the plane, and outer surface of outer cover 1 is transparent material with photodiode 3 over against part with inner surface of outer cover 2.The user uses for ease, and the present invention also comprises pilot lamp 4 and hummer 5, is transparent material in the frame of broken lines among the figure.
Should be appreciated that outer surface of outer cover 1 and inner surface of outer cover 2 should be transparent material not easy to wear, shock proof, comprise polymethylmethacrylate, polystyrene, glass, polycarbonate, poly(4-methyl-1-pentene).
Fig. 2 is the plano-convex lens principle schematic, establish with the corresponding spherical radius of the convex surface of plano-convex lens be r, its centre of sphere is C.The incident ray AB of and parallel primary optical axis very near apart from primary optical axis does not have refraction ground and does not become light AD and incide on the convex surface, and CD is a normal, and incident angle is α (very little); If the refractive index of lens is n, then its refraction angle is approximately n α, can know OD≤r by figure; OD≤L, L are the plano-convex lens focal length, then
Therefore
Spherical radius r according to plano-convex lens can calculate plano-convex lens focal length L; Photodiode 3 is placed plano-convex lens focal length L place, can converge the flashlight of incident, reduce the loss of light signal; Improve the sensitivity of photodiode, strengthen the receptivity of photon receiving end.
Should be appreciated that the visible light signal that comprises unlocking cipher that photodiode will receive converts electric signal into.
The foregoing description among the present invention has only been done exemplary description, and those skilled in the art can carry out various modifications to the present invention under the situation that does not break away from the spirit and scope of the present invention after reading present patent application.
