[0015] Compared with the prior art, the beneficial effects of the utility model are:
[0016] 1. The utility model is equipped with an auxiliary mechanism, which can make the recognition lens accurately recognize the face in different environments and improve the recognition accuracy. When the monitoring device is installed outdoors, due to the changeable outdoor weather, the external sunlight, rain and dark external light will cause the recognition lens to recognize the face unclearly, thereby reducing the recognition agility of the recognition lens. Therefore, an auxiliary mechanism is needed to enable the recognition lens to accurately recognize the face. The sun visor is used to block the external sunlight to prevent the sunlight from irradiating the recognition lens. The rain shield is used to protect the recognition lens to prevent rain from hitting the recognition lens. One end of the fill light is moved into the installation groove so that the first power-on module is in contact with the second power-on module, and at this time the electromagnet is in contact with the magnet body. The electromagnet is energized to absorb the magnet body. The fill light is installed in the installation groove. When the external light is dark, the fill light is turned on to illuminate the face of the person.

[0017] 2. The utility model is equipped with a cleaning and protection mechanism to clean and protect the identification lens. If the identification lens is outdoors for a long time, dust will be adsorbed on the identification lens, which will affect the identification function of the identification lens. At the same time, when the identification panel is not in use, the existing identification panel does not have the function of preventing dust from the identification lens, which leads to increased cleaning intensity and cleaning cycle in the later stage. The elastic cleaning plate has a certain elasticity and plasticity. The elastic cleaning plate is fixed to the threaded groove through a threaded rod. Then, the motor drives the threaded screw to rotate, and the limiting rod limits the slider, so that the slider moves on the threaded screw. The movement of the slider drives the converter to move, which drives the elastic cleaning plate to move to wipe the dust on the identification lens. At the same time, when the identification lens is not in use, the second strong magnet is adsorbed with the first strong magnet, and the protection plate is used to prevent dust from the identification lens, so the identification lens is cleaned and protected, reducing the intensity of manual cleaning in the later stage.

[0028] See also Figure 1 , Figure 2 and Figure 3 The outer wall of the recognition panel 1 is provided with an auxiliary mechanism, which is used to enable the recognition lens 3 to accurately recognize the face in different environments and improve the recognition accuracy. The auxiliary mechanism includes a sun visor 5, which is arranged on the outer wall of the recognition panel 1, and a rain shield 6 is installed on the outer wall of the sun visor 5.

A magnet body 12 is installed on the outer wall of the fill light 10, and a condenser 13 is installed on the outer wall of the recognition panel 1. When the monitoring device is installed outdoors, due to the changeable outdoor weather, when the external sunlight, rain and dark light are exposed, the recognition lens 3 will not recognize the face clearly. , which reduces the recognition agility of the recognition lens 3, so an auxiliary mechanism is needed to enable the recognition lens 3 to accurately recognize the face. The sun visor 5 is used to block the external sunlight to prevent the sunlight from irradiating the recognition lens 3. The rain shield 6 is used to protect the recognition lens 3 to prevent rain from hitting the recognition lens 3. One end of the fill light 10 is moved to the installation groove 7, so that the first power-on module 8 and the second power-on module 11 are in contact, and at this time the electromagnet 9 is in contact with the magnet body 12. The electromagnet 9 is energized to adsorb the magnet body 12, and the fill light 10 is installed in the installation groove 7.

[0030] Working principle: In special occasions, it is necessary to use a monitoring device to identify internal staff. The mounting seat 4 is used to install the identification panel 1. The staff is photographed through the identification lens 3. The display screen 2 is used to display the face of the staff, and then the verification is passed to allow the staff to pass. When the monitoring device is installed outdoors, due to the changeable outdoor weather, when the outside sun shines, the rain hits, and the outside light is dark, the recognition lens 3 will not recognize the face clearly, and reduce the recognition agility of the recognition lens 3, so an auxiliary mechanism is needed. Thereby, the recognition lens 3 can accurately recognize the face. The sun visor 5 is used to block the sunlight from the outside to prevent the sunlight from irradiating the recognition lens 3. The rain shield 6 is used to protect the recognition lens 3 to prevent rain from hitting the recognition lens 3.

The condenser plate 13 prevents the light of the fill light 10 from diverging, so that the recognition lens 3 can clearly recognize the face of the person, and avoids the recognition accuracy of the recognition lens 3 being affected by the external environment. The recognition lens 3 is outdoors for a long time, which will cause dust to be adsorbed on the recognition lens 3, thereby affecting the recognition function of the recognition lens 3. At the same time, when the recognition panel 1 is not in use, the existing recognition panel 1 does not have the function of dustproofing the recognition lens 3, which leads to the strengthening of the later cleaning intensity and cleaning cycle. The elastic cleaning plate 22 has a certain elasticity and plasticity. The elastic cleaning plate 22 It is fixed to the threaded groove 20 through the threaded rod 21, and then the motor 15 works to drive the threaded screw 16 to rotate, and the limit rod 18 limits the slider 17, so that the slider 17 moves on the threaded screw 16, and the movement of the slider 17 drives the converter 19 to move, which drives the elastic cleaning plate 22 to move to wipe the dust on the recognition lens 3. At the same time, when the recognition lens 3 is not in use, the second strong magnet 25 is adsorbed with the first strong magnet 24, and the protection plate 26 is used to protect the recognition lens 3 from dust, so that the recognition lens 3 is cleaned and protected, reducing the intensity of manual cleaning in the later stage.
