Non-contact laser lock based on light conducting optical fiber

Abstract

The invention relates to an electronic lock, in particular to a non-contact laser lock based on a light conducting optical fiber. The lock comprises an unlocking panel, a circuit board, the light conducting optical fiber, a main control module, an electronic lock, a display screen, an input key and a power supply, wherein through holes penetrating forwards and backwards are formed in the unlocking panel; a layer of toughened glass is laid at the front part of the unlocking panel; multiple photosensitive resistors are arranged on the circuit board; one end of the light conducting optical fiber is aligned to the through hole in the back part of the unlocking panel, and the other end is aligned to the photosensitive resistors; each through hole is corresponding to single photosensitive resistor; the circuit board, the input key and the display screen are all connected with the main control module; the main control module controls the opening and the closing of the electronic lock; and the power supply respectively supplies power to the circuit board, the main control module and the electronic lock. The lock is simple in structure; the unlocking panel can prevent the electric shock damage, so that the lock is safer and more reliable; and in addition, as the application of the light conducting optical fiber allows the main control module and other modules to be mounted in safer positions in a door, even if a thief forcedly disassembles the lock by violence, the modules of the control part cannot be influenced.

Description

technical field [0001] The invention relates to an electronic lock, in particular to a non-contact laser lock based on a light-guiding optical fiber. Background technique [0002] Electronic password lock is an electronic product that controls the operation of circuits or chips through password input, thereby controlling the closing of mechanical switches and completing the tasks of unlocking and locking. There are many types of it, including simple circuit products and chip-based cost-effective products high product. Now the widely used electronic combination lock is based on the chip as the core and realized by programming. In the field of security technology prevention, the electronic combination lock with anti-theft alarm function replaces the traditional mechanical combination lock and overcomes the mechanical combination lock. The shortcomings of less passwords and poor security performance have greatly improved the combination lock both technically and in performance...
