Embodiment 1

[0024] see figure 1 and figure 2 According to the present invention, the light-controlled door lock that is convenient for managing user rights includes an optical signal receiving module 1 , an equalization shaping module 2 , a decoding module 3 , a microprocessor module 4 and a protocol conversion module 5 . The optical signal receiving module 1 is used to convert the optical signal containing ID number information and password information emitted by the photon key into an electrical signal, and the code type of the optical signal emitted by the photon key is a CMI code. The optical signal receiving module 1 includes a photodiode 11 , a signal amplifier 12 and a bandpass filter 13 , and the photodiode 11 and the bandpass filter 13 are electrically connected to the signal amplifier 12 respectively. In this embodiment, the photodiode 11 is an avalanche photodiode, and the signal amplifier 12 is a transimpedance amplifier.

[0025] The avalanche photodiode is a p-n junction ...

Embodiment 2

[0033] see Figure 5 , this embodiment is similar to Embodiment 1, and the same thing is that they all include an optical signal receiving module 1, a microprocessor module 4 and a protocol conversion module 5; the difference is that in this embodiment, the optical Between the signal receiving module 1 and the microprocessor module 4 are a primary signal amplifier 6, a secondary signal amplifier 7 and a demodulator 8 electrically connected in sequence, and the primary signal amplifier 6 is used for optical signal receiving module 1 The output current signal is converted into a voltage signal, and the voltage signal is amplified and output; the secondary signal amplifier 7 is used to continue to amplify the signal output by the primary signal amplifier 6 until the microprocessor module 4 can Processed signal: the demodulator 8 is used to demodulate the ID signal transmitted from the secondary signal amplifier 7 according to the transmitted ID format, and transmit it to the proc...

Abstract

The invention relates to a light control door lock convenient for managing user authority. The light control door lock comprises a light signal receiving module, a microprocessor module and a protocol conversion module, wherein the light signal receiving module is used for converting a light signal containing ID number information transmitted by a photon key into an electric signal; the microprocessor module is used for controlling the opening or closing of the door lock according to the electric signal; and the protocol conversion module is used for performing protocol conversion of the ID number and transmitting the ID number to an upper computer. In the light control door lock provided by the invention, the protocol conversion module performs protocol conversion of the ID number and transmits the ID number to the upper computer, and the upper computer monitors the conditions of time, frequency and the like of opening the door by each user so as to set and manage the user authority.

Description

technical field [0001] The invention relates to a light-controlled door lock, in particular to a light-controlled door lock which is convenient for managing user authority. Background technique [0002] In the existing control system, the fingerprint identification control system is widely used in various fields, especially in the fields of user identification, security, management and other related fields. It is now widely used in access control systems and attendance systems. Due to the uniqueness of fingerprints, the identification of fingerprint information can be used to determine personal information. However, since most of the fingerprint identification devices are fixed somewhere, the user's fingerprint information is likely to be left on the fingerprint identification device, resulting in information loss and potential safety hazards. [0003] Visible light communication is a communication method that uses light waves as the transmission medium. It uses high-speed ...
