Light-operated access control device with bidirectional authentication function

Abstract

The invention discloses a light-operated access control device with a bidirectional authentication function. The light-operated access control device comprises a light-operated access control lock and a movable unlocking terminal, wherein the light-operated access control lock comprises a light receiving module, a lock control module, a controlled module, a display module, a communication and alarm module and a power module; the movable unlocking terminal comprises a light emission module, a display and scan module and a terminal control module; the light-operated access control lock is used for receiving and verifying information sent by the movable unlocking terminal, generating and displaying response and authentication information, controlling an access control to be opened and closed, and sending a working state of the access control and alarm information; the movable unlocking terminal is used for sending the related information of unlocking by the light emission module, and resolving the related response and authentication information which is displayed by the display module of the light-operated access control lock and received by the display and scan module; the movable unlocking terminal is used for sending information by light, and scanning, identifying and displaying the information by a camera and a scan head. The light-operated access control adopts the bidirectional authentication mechanism, thus being preferable in safety, privacy and uniqueness.

Description

technical field [0001] The invention relates to the technical field of optical communication, in particular to an optical control access control device with two-way authentication. Background technique [0002] Visible Light Communication (VLC for short) technology. VLC technology utilizes the feature that LEDs can emit high-frequency flickering lights that cannot be perceived by the human eye. At the data sending end, the high-frequency flickering of the LED is used to carry the signal, and at the receiving end, the photosensitive element with the same fast response time is used. A method of collecting signals to realize wireless communication. [0003] At present, the wireless access control system mainly adopts radio frequency technology, which has good penetration, so radio frequency signals are easily interfered by electromagnetic waves, intercepted and duplicated, resulting in leakage of unlocking information and property loss. [0004] Visible light is free from ele...
