Embodiment 1

[0027] Such as Figure 1 ~ Figure 2 As shown, the present invention can automatically control the brightness of the vein fingerprint face composite recognition system, comprising a support frame 1, a vertical adjustment groove 2 is arranged on the support frame 1, a sliding block 3 is arranged on the vertical adjustment groove 2, and the sliding block 3 can move along the vertical adjustment groove 2 or be fixed on the vertical adjustment groove 2, the sliding block 3 is provided with a mounting rod 4, the mounting rod 4 is provided with a horizontal adjustment groove 5, and the horizontal adjustment groove 5 is provided with a fixing device 6 , the fixing device 6 can move along the horizontal adjustment groove 5 or be fixed on the horizontal adjustment groove 5, the lighting device 10 is also arranged on the support frame 1, the lighting device 10 is connected with a controller, and the function of the controller is to control the angle of the lighting device 10 and light in...

Embodiment 2

[0030] The present invention is based on embodiment 1, and the present invention is further described.

[0031] Such as Figure 1 ~ Figure 2 As shown, the present invention can automatically control the brightness of the vein fingerprint face complex recognition system, the support frame 1 can be fixed on the wall through the threaded fastener 9, the threaded fastener is selected from expansion screws, and the expansion screws are preferably metal expansion screws The fixation of the expansion screw is to use the wedge-shaped slope to promote the expansion to generate friction and grip force to achieve the fixing effect. The expansion screw is composed of a screw and an expansion tube. The tail of the screw is conical, and the inner diameter of the cone is larger than the inner diameter of the expansion tube. When tightening, the screw moves outward, and the axial movement of the thread moves the cone part, thereby forming a large positive pressure on the outer peripheral surf...

Embodiment 3

[0033] The present invention is based on embodiment 1, and the present invention is further described.

[0034] Such as Figure 1 ~ Figure 2As shown, the present invention can automatically control the brightness of the vein fingerprint face composite recognition system, the number of support frames 1 is two, and the installation rod 4 is located between the two support frames 1, and the two ends of the installation rod 4 are respectively located on the support frames. 1, the installation rod 4 is moved to make it more stable, the installation rod 4 can move along the vertical adjustment groove 2 on the support frame 1, thereby adjusting the position of the installation rod 4, the fixing device 6 is a hook or a threaded fastener, through the hook Or threaded fasteners fix the vein recognition instrument on the mounting rod 4, and select different fixing devices 6 and their quantity according to the size and model of the vein recognition instrument, so as to achieve the best fi...

Abstract

The invention discloses a vein-fingerprint-face composite recognition system with an automatic light brightness control function. The system includes a support frame which is provided with a verticaladjusting slot. A sliding block is arranged on the vertical adjusting slot. The sliding block can move along the vertical adjusting slot or be fixed to the vertical adjusting slot. A mounting rod is arranged on the sliding block. The mounting rod is provided with a horizontal adjusting slot. A fixing device is arranged on the horizontal adjusting slot. The fixing device can move along the horizontal adjusting slot or be fixed to the horizontal adjusting slot. The support frame is further provided with lighting equipment which is connected with a controller. The controller is used for controlling the angle and light intensity of the lighting equipment. The system is more convenient to install and more flexible in installation position. The angle and light intensity of the lighting equipmentare adjusted according to the illumination conditions of the external environment so that the vein-fingerprint-face composite recognition system has a better recognition effect.

Description

technical field [0001] The invention relates to the field of biometric identification, in particular to a vein fingerprint and human face complex identification system that can automatically control brightness. Background technique [0002] The so-called biometric technology refers to the close combination of computer and high-tech means such as optics, acoustics, biosensors and biostatistics, using the inherent physiological characteristics of the human body such as fingerprints, finger veins, faces, irises, handwriting, voice, gait, etc. and other behavioral characteristics for personal identification. Traditional identity verification methods include identification items such as keys, certificates, and ATM cards, and identification knowledge such as user names and passwords. However, due to the use of external objects, once the identification items and identification knowledge that prove identity are stolen or forgotten, their identity is easy. be impersonated or replace...
