Full fusion type under-screen finger vein recognition lock control device

Abstract

The invention discloses a full fusion type under-screen finger vein recognition lock control device. The device comprises a front shell and a rear shell, a main board is arranged in a cavity between the front shell and the rear shell, a chip with a finger vein algorithm and a lock control main chip are integrated on the main board, and the chip with the finger vein algorithm takes a UART as a communication interface to serve as slave equipment of the lock control main chip; and the chip with the finger vein algorithm is respectively connected with a digital touch panel, an upper infrared lamp panel, a lower infrared lamp panel and a camera module.

Description

technical field [0001] The invention relates to an under-screen finger vein recognition and locking device, in particular to a fully integrated under-screen finger vein recognition and locking device. Background technique [0002] With the popularization of living biometric identification technology, products such as smart locks, smart doors, and smart safes have developed rapidly. In a very short period of time, the selling points of such products have evolved from the realization of functions to the aesthetic appearance and durable quality. [0003] But at this stage, in the field of finger vein recognition, the finger vein recognition module and the lock control module are separate modules. Generally, manufacturers can only purchase two related modules for assembly. However, during the splicing process, there will be a splicing gap between the two modules, and a hole will be left on the identification device, which will greatly affect the appearance, and the two modules m...

Problems solved by technology

[0003] But at this stage, in the field of finger vein recognition, the finger vein recognition module and the lock control module are separate modules. Generally, manufacturers can only purchase two related modules for assembly. However, during the splicing process, there will be a splicing gap between the two modules, and a hole will be left on the identification device, which will greatly affect the appearance, and the two modules must be Connecting through a third-party communication cable increases the cost of production materials and increases the difficulty of factory assembly

[0004] In order to solve the above problems, in the field of locks for this kind of finger vein products, the mode of slide lock is generally used to solve the aesthetic problem, but this method obviously pushes up the cost of materials, and the processing process of the product is also more complicated. Conducive to the development of related industries in the field of finger vein products
