Description

Technical Field

[0001] The present invention relates to the technical field of face collection and recognition, and particularly relates to a face collection and recognition device. Background Art

[0002] Face recognition is a biometric identification technology based on the facial feature information of a person. A series of related technologies, such as using a camera or webcam to collect images or video streams containing human faces, automatically detecting and tracking human faces in the images, and then performing facial recognition on the detected human faces, are usually also called portrait recognition and facial recognition.

[0003] During the use of existing face collection and recognition devices, the devices are fixed on turnstiles to perform facial recognition on people entering and leaving. During installation, it is necessary to adjust the installation height according to the usage requirements. When installing and debugging, it is necessary for staff to hold and support them, resulting in inconvenient installation. In addition, during the use of existing face collection and recognition devices, when they are used in locations with a large flow of people, a large number of people quickly pour in within a short period of time, causing the device to work overload, which leads to a continuous increase in the temperature of the electrical components inside. Excessive temperature is likely to cause damage to the device and reduce its service life. Therefore, there is an urgent need for a face collection and recognition device to solve the existing problems. Summary of the Invention

[0004] The purpose of the present invention is to provide a face collection and recognition device to solve the above problems.

[0005] The present invention achieves the above purpose through the following technical solutions:

A mounting mechanism is fixed in the middle of the back end of the back plate. Fastening mechanisms are symmetrically arranged on the mounting mechanism. And a cooling mechanism is arranged below the back end of the back plate.

[0007] The fastening mechanism includes a guide rod slidably connected to the mounting mechanism. One end of the guide rod is fixed with a fastening plate. A compression spring is installed on the back end of the fastening plate. And one end of the compression spring is connected to the mounting mechanism. The compression spring is located outside the guide rod.

[0008] The cooling mechanism includes a frame fixed on the back plate. The frame is of a hollow structure. A semiconductor refrigerating sheet is installed in the middle of the frame. A heat dissipation fan is arranged outside the heat release end of the semiconductor refrigerating sheet. And a protective net is arranged outside the heat dissipation fan. The protective net is fixedly connected to the frame. And through holes corresponding to the semiconductor refrigerating sheet are opened on the back plate.

[0009] Further, the installation mechanism includes a mounting plate, a fixing bracket, fixing bolts and fixing nuts, wherein the mounting plate is connected to the back plate by bolts.

[0010] By adopting the above technical solution, it is convenient to fix the device on the turnstile through the installation mechanism.

[0011] Further, there are two groups of the fixing brackets, and the fixing brackets are made of elastic materials and are in a semi-circular structure.

[0012] By adopting the above technical solution, it is convenient to connect the fixing brackets to the mounting posts on the turnstile, thereby fixing the device.

[0013] Further, the fixing bolts penetrate through the fixing brackets, and the fixing nuts are rotatably connected to the fixing bolts.

[0014] By adopting the above technical solution, it is convenient for the staff to insert the fixing bolts into the two groups of fixing brackets and install the fixing nuts at one end, thereby limiting the fixing brackets and further fixing the device.

[0015] Further, a collection mechanism is installed on the side of the machine shell away from the back plate, and the collection mechanism includes a display screen, a camera and a fill light.

[0016] By adopting the above technical solution, it is convenient to collect and identify human faces through the collection mechanism.

[0017] Further, the display screen, the camera and the fill light are all fixedly connected to the machine shell.

[0018] By adopting the above technical solution, the camera can be used to capture and collect human faces and display them externally through the display screen, and at the same time, the fill light can improve the surrounding environment at both ends.

[0019] Further, an electric control mechanism is arranged on the side of the back plate opposite to the installation mechanism, and the electric control mechanism includes a circuit board, a main control chip, a storage module, an identification module and a signal transceiver module.

[0020] By adopting the above technical solution, it is convenient to control the circuit signals in the device through the electric control mechanism.

[0021] Further, the display screen, the camera and the fill light are all connected to the circuit board.

[0022] By adopting the above technical solution, it is convenient to connect the display screen, the camera and the fill light through the circuit board, thereby realizing the control of them.

[0023] Further, the main control chip is connected to the circuit board, and the signal transceiver module is connected to the circuit board.

[0027] The specific working principle is as follows: The staff first separates the fixing bolt and the fixing nut, and then makes the two sets of fastening plates in the fastening mechanism located outside the support column of the turnstile. At this time, the fastening plates abut against the support column and drive the guide rod to move along the installation mechanism, and compress the compression spring. Through the reaction force of the compression spring, the two sets of fastening plates clamp the support column, so as to temporarily fix the device, without the need for the staff to support it, which is convenient for the staff to adjust its height. After the height adjustment is completed, the staff uses the fixing bolt and the fixing nut to fix the device. During use, the camera captures the face. The shooting information of the camera is transmitted to the main control chip through the signal transceiver module. The recognition module can analyze and identify the photo information received by the main control chip, store the shooting information through the storage module, and display it externally through the display screen. At the same time, the supplementary light can improve the surrounding environment brightness. At the same time, during use, the heat absorption end of the semiconductor refrigeration sheet in the frame continuously absorbs the heat in the device. These heats are discharged from the heat dissipation end of the semiconductor refrigeration sheet and discharged to the outside through the heat dissipation fan, so as to cool the device, avoid the internal temperature from rising, prevent the device from being damaged, improve its service life, and at the same time, the protective net can prevent large foreign objects from entering the frame.

By setting the fastening mechanism, when installing and adjusting the height of the device, the staff separates the fixing bolt and the fixing nut, and then makes the two sets of fastening plates in the fastening mechanism located outside the support column of the turnstile. At this time, the fastening plates abut against the support column and drive the guide rod to move along the installation mechanism, and compress the compression spring. Through the reaction force of the compression spring, the two sets of fastening plates clamp the support column, so as to temporarily fix the device, without the need for the staff to support it, which is convenient for the staff to adjust its height;

[0030] 2. By setting up a cooling mechanism, during the use process, the heat absorption end of the thermoelectric cooler in the frame can continuously absorb the heat inside the device. This heat is discharged from the heat dissipation end of the thermoelectric cooler and emitted to the outside through the cooling fan, thereby cooling the device, avoiding the increase of internal temperature, preventing the device from being damaged, increasing its service life. At the same time, the protective net can prevent large foreign objects from entering the frame. Description of the Drawings
