Problems solved by technology

However, due to being easily affected by stray light such as sunlight, the optical signal receiving end can easily receive the optical signal transmitted by the optical signal transmitting end only at a short distance, so the application of wireless optical communication technology has not made great progress.

Abstract

The invention relates to a photon key with a long communication distance. The photon key comprises a microprocessor unit, a driving unit and a light emitting unit, wherein the microprocessor unit is used for controlling the driving unit, so that the driving unit drives the light emitting unit to rapidly fizzle; the light emitting unit comprises a light emitting diode, a light emitting angle of which is less than or equal to 30 DEG. Through setting the light emitting angle of the light emitting diode to be less than or equal to 30 DEG, the photon key with the long communication distance, provided by the invention, has the advantages of small light emitting angle, good light focusing effect and high brightness; therefore, the photon key provided by the invention not only is convenient to be aligned with a door lock during unlocking but also can be used for unlocking the door lock beyond dozens of centimeters, so that a feeling of no limitation from distance or capability of remotely unlocking is created for users, the user experience is greatly improved and easiness for winning favors of the users is also obtained.

Description

technical field [0001] The invention relates to a client terminal of an access control system, in particular to a photonic key with a long communication distance. 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. Fingerprin...
