Security door photoelectric coded lock system

Abstract

The invention discloses a security door photoelectric coded lock system. The security door photoelectric coded lock system comprises an electric control lock, a mechanical anti-theft lock, a key matched with the mechanical anti-theft lock, a handheld optical code generating device, an optical code receiving device, a verifying device and a control device. The optical code receiving device receivesoptical code signals of the handheld optical code generating device, the verifying device is connected with the optical code receiving device, the control device is connected with the verifying device, and the electric control lock and the mechanical anti-theft lock are both connected with the control device. The security door photoelectric coded lock system simultaneously has a novel photoelectric code anti-theft mode and a mechanical anti-theft mode, the code cracking difficulty is improved by arranging code chips in the locks and the key, the code signals are transmitted through light raysin a photoelectric conversion mode, and the defect that wireless signals are easy to intercept illegally is overcome.

Description

technical field [0001] The invention belongs to the technical field of locks, in particular to an anti-theft door photoelectric combination lock system. Background technique [0002] Traditional mechanical anti-theft locks are simple in structure and principle, cheap in price, and widely applicable. For example, tumbler locks are currently the most widely used type of locks. The anti-theft performance of the anti-theft lock depends on the two aspects of anti-violence opening and anti-technical opening. For anti-violence opening, as long as the lock manufacturer uses qualified materials and manufactures according to relevant technical specifications, it can generally be guaranteed. For anti-technical opening, it depends to a certain extent on the size of the anti-theft lock secret key. The larger the secret key, the harder it is to crack, but this usually means that the anti-theft lock structure is more complicated, the production process requires high requirements, and the c...
