Background
The narrow entrance guard terminal is a terminal device which controls entrance guard by means of person identity authentication in modes of biological identification or IC card, two-dimensional code and the like.
The biological recognition middle finger vein refers to human finger vein. Finger vein recognition is an advanced biological internal feature recognition technology. The technology irradiates a finger by near infrared light, shoots an image of a finger vein, extracts characteristic data from the image by using a specific algorithm, stores the extracted characteristic data during registration, compares the extracted characteristic data with the stored characteristic data during identification, and gives an identification comparison result, thereby achieving the function of identity identification. The method is a popular biological human body identification method at present, and a device for performing differential authentication by using finger veins is developed rapidly at present.
At present, the traditional access control system has a plurality of insufficient places in the use process.
The applicability is poor: some groups have few fingerprint characteristics and are difficult to collect; in addition, the utility model is difficult for the old and farmers.

Originally, adopt split machine more, module and host computer separation, it is very inconvenient and the debugging difficulty to install during the in-service use.
Among the traditional access control system: and adopting an IC card mode to carry out identity recognition. The IC card must be properly kept and managed, and if the IC card is lost, the IC card cannot be correctly withdrawn from the cabinet. COPY is easily caused by reading and writing of the IC card, and the security level is very low.
And carrying out identity recognition in a password mode. The password must be kept in mind, and the article cannot be correctly accessed without the password, so that the use is inconvenient. The password is lost, decoded and stolen with low security level.
And carrying out identity recognition in a bar code mode. Like the IC card, it is necessary to keep the medium properly, and it cannot be used for a long time, and it cannot be used in places such as a natatorium, and has a great limitation.
The fingerprint mode carries out identification, though can solve above three kinds of problems, the precision of fingerprint is lower, and the finger receives the environmental impact greatly, for example uses in natatorium, perhaps fingerprint wearing and tearing crowd to have the problem.
The face recognition mode is used for identity recognition, and the cost of the existing face recognition scheme is relatively high. In some places, such as a dressing room, the privacy aspect is involved, and a camera for face recognition can be an unacceptable pain point.

Detailed Description
Embodiment 1, this embodiment is an entrance guard terminal for finger vein recognition, as shown in fig. 1, including an entrance guard switch for controlling the switch by generating a control signal 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 gate with the registered finger vein image of the person in the memory, if the finger vein image is registered and is considered to pass the gate, a control signal is generated to control the opening of the access control switch and let the person pass the gate, otherwise, the control signal is generated to control the access control switch not to be opened and let the person pass the gate, so that the control of the access gate 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.
The entrance guard terminal for finger vein recognition in the embodiment is also called a finger vein recognition all-in-one machine, the current mainstream ARM scheme is adopted, one 8-core CPU is carried, the memory of 2G and the storage of 16G are carried, the operating system is android 6.0.1, the system is displayed as a 10.1-inch liquid crystal display screen, the resolution ratio is 1280-800, and a multi-point capacitive touch screen is arranged, so that the touch operation can be conveniently carried out. 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. The finger vein module is communicated with the mainboard 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 local library for modeling, identifying, comparing and other operations, certain requirements are imposed on the transmission rate of the USB, and a USB interface circuit is specially redesigned.
