Description

Palm vein recognition access control scheme with new lock cylinder

Technical field

The invention relates to an identifiable door lock, and more particularly to a palm vein recognition access control scheme with a novel lock cylinder.

Background technique

Smart locks have the benefits of security, convenience, and advanced skills. 1. Safety: 1 In the normal residential security environment, the door lock handle opening method usually cannot ensure the safety performance. It is easy to drill the small hole from the door and then use the wire rolling handle to open the door. Recently, the smart lock has patented skill guarantee. The safety handle button is added to the indoor handle setting. The safety handle button needs to be pressed to roll the handle door to open, which brings a safer working environment. (Together with the needs of the user, after a brief operation, this function can be selectively set.) 2 The usual fingerprint code lock has the danger of missing code. Recently, the smart lock also has the function of virtual code code, that is, in front of or behind the registered code, it is possible to input the ambiguous number as the dummy code, which is useful for avoiding the leakage of the registered code and opening the door lock together. 3 recent smart lock palm touch screen will automatically appear, 3 minutes will actively lock up. Is the password code set now, the door lock is now open or closed, the number of passwords or door card registration, as well as the battery replacement prompt, the lock tongue is blocked, the low voltage and other conditions are encountered, the screen appears, intelligent control. 2, convenience: 1 usually fingerprint lock is not convenient when using the function of password/fingerprint registration, especially when the elderly and children use it, the smart lock that comes out recently can open its common voice prompt function, which makes the operator's operation more concise. Easy to understand. 2 The smart lock is different from the usual mechanical lock and has an active electronic induction determination system. It will actively sense that when the door is closed, the system will be actively locked. The smart lock can pass the fingerprint, the touch screen, and the card opens the door lock. 3 Traditional mechanical locks Everyone has no special concern about its appearance. Today's smart locks are not only suitable for everyone's tastes from the appearance of the plan, but also invented the smart locks like Apple's smart feeling. Intelligent locks are now quietly available. 4 Security: The recent smart lock is different from the previous method of opening and rescanning. The scanning method is very simple. You can place your finger on the top of the scan and scan from top to bottom. You don't need to press your finger on the scan. The method further reduces fingerprint residue, greatly reduces the possibility of fingerprint being copied, and is safe and exclusive.

In still further embodiments, the engaging portion is located outside of the flap locking structure, directly above the flap, the height of which is such that the flap can block the height of the upper edge of the flap of the lock cylinder.

In still further embodiments, the identification device is a palm vein recognition device.

In still further embodiments, the flap and the attracting block are made of iron or nickel, and the attracting block is a permanent magnet.

In still further embodiments, the stylus disk is constructed of a permanent magnet having a metal conductive layer attached thereto, and the stylus is made of iron or nickel.

In still further embodiments, the stylus is constructed of permanent magnets with a metal layer attached to the surface.

In still further embodiments, the number of attracting blocks is three, and the triangular structure is on the stylus disc.

In still further embodiments, the attraction block is 2 to 6 columns.

3. Advantageous effects of the present invention.

(1) In the identification process, the present invention first opens the baffle that blocks the lock cylinder for identification once, and then opens the lock cylinder for secondary identification, and the double identification process can reduce the property loss caused by the recognition error.

(2) The magnetic interference of the present invention can solve the problem of the exposed core of the lock cylinder and prevent the thief from destroying the lock cylinder.

(3) The arrangement of the plurality of styli of the present invention can monitor the problem that the suction of the block to the position is in place, improve the accuracy of the position determination of the block, and has a simple structure and low cost.
