Description

Technical Field

[0001] The utility model belongs to the technical field of access control systems, and in particular relates to a visual intercom access control system based on face recognition. Background Art

[0002] With the rapid development of social economy and the continuous improvement of people's material living standards, intelligent home living styles are becoming more and more popular. At the same time, people are paying more and more attention to the protection of their own safety, and the demand for safe and reliable security systems is becoming increasingly strong, especially in high-end residential areas, commercial office buildings and financial institutions. Security issues are the most important issues in the management area. Not only does management require strengthening the identification of people entering and leaving, but also the technical level in the security field is becoming increasingly strict. The access control system is an important part of building security management, and various identity recognition technologies are used to manage people entering and leaving.

[0003] The existing face recognition-based video intercom access control system generally adopts a direct screw fixing method during the installation process. This method requires drilling holes at the installation site during use. If the device is to be maintained at a later time, the screws need to be removed one by one. The access control system can be inspected only after the disassembly is completed. After the inspection is completed, the installation site needs to be punched again. The original installation holes do not match the screws due to the force or method used by the maintenance personnel during the disassembly process. The holes need to be re-drilled and re-installed, which affects the actual use of the user and reduces the aesthetics of the device, causing a lot of trouble to the user. Therefore, we need to upgrade and transform it based on the existing technology. Utility Model Content

[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0025] like Figure 1 - Figure 5 As shown, a visual intercom access control based on face recognition provided in this embodiment includes a device body 1, which includes a front shell 2, a display screen 3 and an adjustment button 5 are installed in the front shell 2, and a rear cover plate 11 is provided at the rear end of the front shell 2, and a system body 7, a camera 4 and an intercom 8 are arranged in sequence at the connection between the rear cover plate 11 and the front shell 2, an alarm light 9 and a power switch 10 are installed on the right side of the front shell 2, an upper buckle 14 is installed on the outer wall of the rear cover plate 11, a lower buckle 15 is slidably inserted in the upper buckle 14, a mounting plate 16 is provided on the outer wall of the lower buckle 15, a mounting hole 17 is opened in the mounting plate 16, a pre-tightening bolt 18 is inserted in the mounting hole 17, and a latch hole 20 is opened in the upper buckle 14 and the lower buckle 15, and a latch rod 21 is inserted in the latch hole 20.

[0026] Preferably, a heat dissipation hole 6 is provided inside the left shell of the front shell 2. The heat dissipation hole 6 is a plurality of groups of long rectangular strips. By providing the heat dissipation holes 6, the heat generated by the operation of the electronic components inside the device can be evacuated to avoid the accumulation of heat inside the device and affecting the subsequent use of the device. Screw holes 12 are provided in the rear cover plate 11 and the front shell 2. Countersunk bolts 13 are screwed into the screw holes 12. By providing the countersunk bolts 13, the rear cover plate 11 and the front shell 2 can be connected and fixed, which increases the connection and intimacy between the devices and ensures the safety of the device when in use. A limit plate 22 is installed below the pin rod 21, and the limit plate 22 is fixedly connected to the latch rod 21. By setting the limit plate 22, the latch rod 21 can be fixed, which increases the stability and safety of the latch rod 21. A threaded groove is provided at the upper end of the latch rod 21, and a nut 23 is screwed on the latch rod 21. A knob 24 is fixedly provided at the upper end of the nut 23. By setting the nut 23, the latch rod 21 can be fixed and limited, which prevents the latch rod 21 from falling off the device during use. By setting the knob 24, the user can adjust the nut 23 conveniently.

[0027] Preferably, an anti-slip strip 25 is installed on the outer wall of the knob 24, and multiple groups of anti-slip strips 25 are provided. By providing the anti-slip strips 25, the anti-slip performance of the knob 24 is increased to avoid the situation where the hand slips during the rotation of the knob 24. Multiple groups of pre-tightening bolts 18 are provided, and a washer 19 is provided on the movable sleeve of the pre-tightening bolt 18. By providing the washer 19, the wear of the pre-tightening bolt 18 on the mounting plate 16 is reduced.

[0028] The user then pulls the latch rod 21 with the limit plate 22 downward by hand to remove the latch rod 21 from the latch hole 20 of the upper and lower buckles 14 and 15. After removal, the user pulls the upper buckle 14 outward by hand to slide the upper buckle 14 out of the lower buckle 15 and remove it. After removal, the user removes the countersunk bolt 13 in the rear cover plate 11 from the screw hole 12 in turn. After removal, the electronic components inside the device can be repaired and maintained. After the repair is completed, the device can be re-fixed, and the device can be installed and fixed, which is convenient for the user to repair or maintain the device in the later stage, increases the practicality and convenience of the device, and avoids the problem that the device needs to be repeatedly punched and installed to affect the aesthetics.
