Problems solved by technology

However, due to the characteristics of its all-mechanical structure, at the correct password position, the ticking sound of the dial is different. Expert decipherers can quickly decipher the combined password of this type of mechanical lock by listening to the sound, which poses a relatively large security risk.

Embodiment Construction

[0022] The present invention provides a photonic code dial lock, which includes a mechanical dial knob and a photoelectric transceiver assembly, the mechanical dial knob includes at least one dial with a light hole, the photoelectric transceiver assembly includes a light source and a photodetector, and the light source provides The emitted light is irradiated on the photodetector through the light hole on the dial, and the combination lock is opened when the sending and receiving signals are consistent.

[0023] The photoelectric transceiver component also includes an information processing unit, which can code and modulate the light source. The photodetector is used to receive the coded information of the light source, and transmit the received information to the information processing unit for comparison. When the emitted signal of the light source and The combination lock can only be opened when the receiving signals of the photodetectors are consistent.

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 [0003] (1) Technical problems to be solved [0004] The invention overcomes the deficiencies in the prior art and provides a photon cipher code dial lock, which can effectively overc...
