Light-controlled electronic lock system

Abstract

The invention discloses a light-controlled electronic lock system comprising at least one LED (Light Emitting Diode) light signal output unit used for outputting light signals, and a light-controlled electronic lock, wherein the light-controlled electronic lock comprises a receiving unit used for receiving the light signals, a decoding unit used for decoding the light signals to binary data, an unlocking unit used for unlocking the light-controlled electronic lock according to the binary data, a second power supply unit, and an emergency power supply unit used for providing power supply to the units, and a control unit used for controlling the on-off of the emergency power supply unit. Since the lock is controlled by the light signals in the invention, a user can see the irradiation range of visible light and accurately emit the LED light signals without worrying about that the LED light signals can be intercepted by others to leak a password, thereby greatly improving the safety and the user experience. In order to prevent the light-controlled electronic lock system from failing to perform application functions in the case of power failure, the emergency power supply unit is provided, and the utilization performance of the light-controlled electronic lock system is also improved.

Description

technical field [0001] The invention belongs to the technical field of optical communication, and in particular relates to an optical control electronic lock system. Background technique [0002] Most companies or shopping malls have access control systems to enable different people to enter different areas. Most of the existing technologies use radio frequency or infrared technology to achieve the purpose of access control: use a radio frequency door card to swipe the card on the access control system or use an infrared emitting device to emit infrared rays . [0003] However, both radio frequency and infrared have different disadvantages: the radio frequency card can usually only open one access control, although the authority can be added to the access control card, but the process of increasing the authority is very complicated, and the crosstalk of the radio frequency access control card is very serious, multiple radio frequency access control When the cards are stacke...

Problems solved by technology

[0003] However, both radio frequency and infrared have different disadvantages: the radio frequency card can usually only open one access control, although the authority can be added to the access control card, but the process of increasing the authority is very complicated, and the crosstalk of the radio frequency access control card is very serious, multiple radio frequency access control When the cards are stacked together, the functions of each access control card cannot be realized

Infrared light must be transmitted point-to-point, not only needs to be aligned but also because infrared light is invisible to the naked eye, its safety cannot be guaranteed
