Photon coded dial lock

Abstract

The invention discloses a photonic password dial lock, which comprises two parts: a mechanical dial knob and a photoelectric transceiver assembly, wherein the mechanical dial knob part includes multiple groups of dials with light holes, and the position of the light holes is the same as that of each light hole. The specific password numbers on the dial correspond; the photoelectric transceiver assembly includes a coded light source, a photoelectric detector, and an information processing unit. The information processing unit encodes the password and modulates it on the light source. After the photodetector receives the coded information, it is handed over to the information processing unit for comparison, and the mechanical lock is opened only when the received and received passwords are consistent. It can effectively overcome the defect of hearing and deciphering the all-mechanical combination lock, and greatly improve the safety performance of the combination lock.

Description

technical field

[0001] The invention belongs to the field of safety password switch control in the field of automation control, and in particular relates to a photonic password dial lock. Background technique

[0002] Combination locks are widely used in file cabinets, lockboxes, confidential warehouses, etc. Traditional dial-type mechanical combination locks were all the rage, and are still widely used in various security fields today. However, due to the characteristics of its all-mechanical structure, there is a difference in the tone of the ticking sound of the dial at the correct password position. Expert decipherers can quickly decipher the combined password of this type of mechanical lock by listening to the sound, which has a relatively large security risk. Contents of the invention
