Example Embodiment

[0019] The present invention will be further described below in conjunction with the drawings and specific embodiments:

[0020] See figure 1 and figure 2 , The photon key that can be charged via USB of the present invention includes a light signal transmitting module 1, a USB module 2 and a signal conversion module 3. The optical signal transmitting module 1 is used to transmit an optical signal containing an unlocking code. The optical signal transmitting module 1 includes a storage unit 11, a microprocessor unit 12, a driving unit 13, and a light emitting unit 14. The storage unit 11 is used for The unlocking code is stored; the microprocessor unit 12 is used to control the driving unit 13 so that the driving unit 13 drives the light-emitting unit 14 to emit a light signal containing the unlocking code. In this embodiment, the light emitting unit 14 is a light emitting diode.

[0021] The USB module 2 is used to obtain power from the USB host and supply power to the optical si...

Abstract

The invention relates to a photon key rechargeable through USB (Universal Serial Bus). The photon key comprises a light signal emitting module and a USB module, wherein the light signal emitting module is used for emitting a light signal containing an unlocking password, and the USB module is used for obtaining the electric energy of a USB mainframe and supplying power to the light signal emitting module. Since the photon key is provided with the USB module, when the energy of the photon key is used up, the USB module is connected with the USB mainframe to charge the photon key, so that the charging and the using are convenient and no waste battery is generated, so that the environmental protection is realized.

Description

technical field [0001] The invention relates to a client of an access control system, in particular to a photonic key that can be charged through USB. Background technique [0002] The access control system belongs to the category of the public security system and is a high-tech security facility widely used. Most of the existing access control systems are implemented using four technologies: magnetic identification, radio frequency identification, fingerprint identification, and password identification. Magnetic identification and radio frequency identification refer to adding specific magnetic materials and radio frequency chips of specific signals to the access control card respectively, and unlocking by identifying the magnetic medium or radio frequency signal through the access control receiving end. However, there are degaussing and radio frequency interference. , easy to intercept and other problems, thus inconvenient to use and poor security. Fingerprint recognitio...
