Drawings
Fig. 1 is a block diagram of a channel gate structure through which vein recognition is passed according to embodiment 1 of the present invention.
Detailed Description
Embodiment 1, this embodiment is a channel gate through which finger vein recognition passes, as shown in fig. 1, including a gate switch for generating a control signal to control the switch by a computer system, a control terminal having a processor and a memory for generating the control signal; the control terminal is a common computer, compares the detected finger vein image of the person to pass the brake with the registered finger vein image of the person in the memory, if the finger vein image is registered and the finger vein image is considered to pass the brake, a control signal is generated to control the switch of the brake to be opened, the person is released to pass the brake, otherwise, the control signal is generated to control the switch of the brake not to be opened, the person is not released to pass the brake, and the control of the pass-through brake is realized.
As shown in fig. 1, the identification apparatus in this embodiment includes an IC card reader or a two-dimensional code module in addition to the main identification apparatus finger vein module, in practice, these two modules of non-biological identification modes can be selected, the output end of the finger vein module, the IC card reader or the two-dimensional code module is connected to the control terminal through a USB interface, in the control terminal, the data output by the finger vein module is compared with the data stored in the memory to generate a control signal to control whether the gate switch is turned on, and if a person does not register a finger vein image, but has an IC card or a two-dimensional code, etc., identification can be performed through the backup IC card reader or the two-dimensional code module. In addition, the system also comprises a display and a loudspeaker, wherein the display is connected with the control terminal through a DVI interface, and the loudspeaker is directly inserted into an audio interface of the control terminal. In addition, a touch screen can be arranged as an input device to be connected with the control terminal.
According to the finger vein recognition all-in-one machine, a control terminal adopts a current main stream ARM scheme, one 8-core CPU, a 2G memory and a 16G memory are carried, and an operating system is an android 6.0.1 system. CPU dominant frequency 2GHz designs intelligent power management circuit to can directly support HDMI output, WIFI/bluetooth (can support 2.4G/5 GWIFII) in an organic whole. Through brand-new circuit and system design, two finger vein recognition modules can be simultaneously mounted on the same mainboard. Greatly reducing the cost and complexity of installation.
The finger vein module is communicated with the control terminal through the USB interface, and the USB communication interface has the characteristics of high transmission rate, simple structure and the like. Because the finger vein module needs to transmit the collected human finger vein image to a storage local library in a memory for modeling, identification, comparison and other operations, a certain requirement is imposed on the transmission rate of the USB, and a USB interface circuit is specially redesigned.
The two-dimensional code module or the IC card reader-writer is used for supplementing a finger vein recognition mode, and the two-dimensional code module is used for generating and collecting dynamic two-dimensional codes of the mobile phone. Both of these approaches may be used when the user is unable to use finger vein information at some time.

3. The finger vein has better anti-interference performance; fingerprints are susceptible to external stains and environmental moisture and cannot be correctly identified.
4. Some groups (such as coal miners in coal mines) have unclear fingerprint lines due to long-term finger friction, so that the fingerprint identification is difficult. The application range of finger vein recognition is relatively wider.
Compared with all environments adopting biological recognition, the finger vein recognition mode has a plurality of advantages. The method is convenient to be applied to various scenes efficiently, conveniently and accurately.
The unique DNA cause, different finger vein information of different people cannot be identical.
The stability is not affected by external environmental factors and surface characteristic changes (such as rough and dry skin).
The precise vein information imaging is complex, and the algorithm is delicate.
Living blood properties form natural living features.
The vein information can be acquired only by the acquisition equipment with special anti-counterfeiting property under specific conditions.
The convenient finger is the most flexible part of the human body, and the collection is convenient and quick.
The channel gate that finger vein discernment of this embodiment passes through has following characteristics: 1. replacing the previous discrete design with an integrated solution. The consistency of the whole machine is improved, and various inconveniences in the actual use process, such as wiring, installation, signal interference and the like, are solved.
