Abstract
The invention provides a USB flash disk photon client. The USB flash disk photon client comprises a flash memory chip with a USB interface, a master control chip, an optical signal modulation circuit in communication connection with the master control chip, a light emitting diode driving circuit in communication connection with the optical signal modulation circuit, and a light emitting diode connected with the light emitting diode driving circuit. The photon client of the invention has a mass storage function of a USB flash disk, and is convenient for storage of information by a client server; and additionally, the USB interface of the photon client is connected with a charging battery, so the client server can provide conveniences for the charging of the photon client, and a dry battery is not individually used by the photon client, thereby the environmental pollution is reduced, and the volume and the weight of the photon client are reduced.
Description
Technical field
The present invention relates to photon gate control system field, relate to a kind of USB flash drive photon client 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, light-operated gate control system is arisen at the historic moment, and light-operated gate control system generally includes photon client and light-operated door lock; The photon client is used to launch the light signal that contains unlocking cipher information; Light-operated door lock is resolved light signal after receiving light signal, if light signal contains unlocking cipher, then controls door lock and opens; Otherwise, then close.Yet generally through dry cell power supply, quality is heavier, and is not portable for existing photon client, uses inconvenient.
Summary of the invention
The technical matters that the present invention solves is that a kind of USB flash drive photon client is provided, and this photon client can realize opening the function of photon door lock, and simultaneously, this photon client can be served as USB flash drive, and is self work power supply through USB interface.
The technical solution adopted for the present invention to solve the technical problems is: a kind of USB flash drive photon client is provided; Comprise the flash chip and the main control chip that have USB interface; Also comprise the light signal modulation circuit of communicating by letter and being connected, the light emitting diode of communicating by letter the LED driving circuit that is connected and being connected with the light signal modulation circuit with LED driving circuit with main control chip.
Preferably, USB interface is connected with rechargeable battery.
Preferably, rechargeable battery is a lithium battery.
Preferably, rechargeable battery is an ickel-cadmium cell.
Preferably, rechargeable battery is a Ni-MH battery.
Preferably, main control chip is an one chip microcomputer.
Preferably, main control chip sends instruction to the light signal modulation circuit, and the light signal modulation circuit will be launched the visible light that contains unlocking cipher through LED driving circuit driven for emitting lights diode after will containing the optical information modulation of unlocking cipher.
Preferably, the modulation system of light signal modulation circuit is amplitude keying modulation or pulse-code modulation.
Beneficial effect of the present invention is that this photon client has the extensive memory function of USB flash drive, in addition; The USB interface of photon client connects its inner rechargeable battery; USB interface is linked to each other with any device with USB interface, can be the charging of photon client easily, the photon client needn't be used dry cell; Reduced the photon client volume, alleviated the weight of photon client, environmental protection is portable more to make the photon client.
