[0002] The camera, also known as computer camera, computer eye, electronic eye, etc., is a kind of video input device, which is widely used in video conferencing, remote medical treatment and real-time monitoring, etc. Ordinary people can also communicate with each other through the camera on the network with image and sound. In addition, people can also use it for current various popular digital image, video processing, etc. The intelligent camera has pedestrian re-identification function, which uses computer vision technology to determine whether there is a specific pedestrian in the monitoring image of the camera, and can be combined with pedestrian tracking technology to realize dynamic tracking of the specific pedestrian path, and make up for the visual limitation of fixed camera.

[0003] Among them, the location of the desert wind power plant, because of the influence of high air flow rate and air dryness all the year round, the water-soluble lubricant for controlling the output position of the camera twist motor is dry, which increases the difficulty of camera twisting. In view of the above problems, the following scheme is proposed. SUMMARY

[0004] To solve the above technical problems, the present application provides an intelligent camera with pedestrian re-identification and dynamic tracking, which comprises a base, the top of the base is fixedly connected with an electric telescopic rod, the end of the electric telescopic rod away from the base is fixedly connected with a pressure frame, the top of the base is fixedly connected with a fixed frame, the top of the fixed frame is fixedly connected with a mounting plate;

[0006] The pressure-applying mechanism includes a base tube fixedly connected to the top of the mounting plate, a sliding tube 1 is slidably connected to the inner wall of the base tube, a sliding tube 2 is slidably connected to the inner wall of the sliding tube 1, a sliding tube 3 is slidably connected to the inner wall of the sliding tube 2, a filter is fixedly connected to the side wall of the sliding tube 3, the inner wall of the through hole at the top of the sliding tube 3 is rotatably connected to the outer wall of the sealing ring, a cleaning component is fixedly connected to the inner wall of the sliding tube 2, and a sealing component is fixedly connected to the side wall of the sliding tube 3. Taking advantage of the large temperature difference between day and night in the desert area and the fact that most lubricating oils are water-soluble greases, a pressure mechanism is provided inside the equipment. Before use, the base is installed in the desired position and the power supply of the electric telescopic rod and the motor is turned on. At this time, the motor drives the camera to rotate through the square telescopic rod to achieve a dynamic tracking effect. After nightfall, the temperature in the desert drops, and the electric telescopic rod generates a contraction force, forcing the pressure frame and the sealing The ring moves downward, and at this time the sealing ring drives the sliding tube three to move downward synchronously. The sliding tube three slides downward along the inner wall of the sliding tube two, so that the sliding tube two covers the air outlet of the filter screen, so that the bottom of the sliding tube three and the top of the obstruction plate form a closed environment. At this time, as the electric telescopic rod contracts, the space of the above-mentioned closed environment gradually shrinks, while the total amount of air inside remains unchanged, causing the internal air to transform into high-pressure gas. When the normal air pressure transforms into high pressure, the overall temperature of the closed environment will increase. At this time, the inside of the equipment is high-pressure and high-temperature gas, and the outside of the equipment is low-temperature gas. Under the state of cold outside and hot inside, small water droplets will slowly condense on the inner walls of the sliding tube two, sliding tube one and base tube, and the small water droplets will slide downward along the inner walls of the above components and mix with the water-soluble grease on the top of the obstruction plate, thereby increasing the viscosity of the lubricating fluid inside the equipment. Through the application of the above components, the equipment can replenish a small amount of water, thereby extending the service life of the internal grease.

[0007] Preferably, the cleaning component includes a sliding plug ring groove opened on the top of the sliding tube 2, a sliding groove is opened on the inner wall of the sliding plug ring groove, a fixing ring is fixedly connected to the inner wall of the sliding tube 2, and a reset spring is fixedly connected to the bottom of the fixing ring.

In view of the problem that the dust content of the airflow in the desert is high, a guide assembly is arranged inside the equipment, wherein the sliding pipe three and the sliding pipe two are in contact, which ensures that the sliding pipe three can rotate along the inner wall of the sliding pipe two and also can slide up and down along the inner wall of the sliding pipe three, and the installation direction of the limiting plate one is consistent with the direction of the filter screen. When the external wind speed is high, the airflow will act on the sidewalls of the limiting plate one, the sliding plate and the limiting plate two, forcing the above-mentioned assemblies to drive the mounting ring and the sliding pipe three to rotate with the sealing ring as the center. At this time, the limiting plate one is rotated by the wind, forcing the filter screen to be in a leeward position, avoiding the direct entry of dust carried by the airflow through the filter screen into the equipment interior; in addition, the above-mentioned sliding pipe three, sliding pipe two, sliding pipe one and base pipe are cylindrical, when the external airflow contacts with the outer wall of the above-mentioned assemblies, the airflow will flow along the outer wall of the above-mentioned assemblies, and two airflow differences with unequal pressure will be formed at both ends of the cylindrical shape, and the unequal airflow will produce regular oscillation at the side of the cylindrical assembly, and the airflow will carry most of the dust to flow synchronously, and the low-flow area is close to the position of the sliding pipe three, and the dust content of the air in this area is low. Through the application of the above-mentioned assembly, the total amount of sand and dust entering the equipment interior is greatly reduced when the equipment is ventilated, and the quality of the internal lubricating oil is ensured.

[0014] The present application has the following beneficial effects:

[0015] (1) The present application utilizes the characteristics of large diurnal temperature difference in desert areas and water-soluble grease of lubricating oil, a pressing mechanism is arranged in the equipment, before use, the base is installed at the required position, and the power supply of the motor and the electric telescopic rod is connected, at this time, the motor drives the camera to rotate through the square telescopic rod, realizing the effect of dynamic tracking, after the time comes to night, the temperature in the desert decreases, at this time, the electric telescopic rod generates a shrinking force, forcing the pressing frame and the sealing ring to move downward, at this time, the sealing ring drives the sliding tube three to move downward synchronously, the sliding tube three slides downward along the inner wall of the sliding tube two, so that the sliding tube two covers the air outlet of the filter screen, so that the bottom of the sliding tube three and the top of the blocking plate form a closed environment, at this time, as the electric telescopic rod contracts, the space of the above-mentioned closed environment gradually decreases, while the total amount of internal air remains unchanged, so that the internal air is converted into high-pressure gas, when the normal air pressure is converted into high pressure, the overall temperature of the closed environment will increase, at this time, the equipment is internally high-temperature and high-pressure gas, and externally low-temperature gas, under the condition of external cold and internal heat, the inner walls of the sliding tube two, the sliding tube one and the base tube will slowly condense small water droplets, which will slide downward along the inner walls of the above-mentioned components and mix with the water-soluble grease on the top of the blocking plate, so as to improve the viscosity of the lubricating liquid in the equipment, through the application of the above-mentioned components, the equipment can supplement a little water, prolonging the service life of the internal lubricating grease.

[0016] (2) The application is aimed at the problem of high dust content in the wind flow of the desert. The device is provided with a guide assembly inside the device, wherein the sliding tube three and the sliding tube two are in contact, which ensures that the sliding tube three can rotate along the inner wall of the sliding tube two and also slide up and down along the inner wall of the sliding tube three. The installation direction of the limiting plate one is consistent with the direction of the filter screen. When the external wind speed is fast, the wind flow will act on the side wall of the limiting plate one, the sliding plate and the limiting plate two, forcing the above components to drive the installation ring and the sliding tube three to rotate around the sealing ring as the center. At this time, the limiting plate one is rotated by the wind, forcing the filter screen to be in a position away from the wind, so as to avoid the wind flow carrying dust directly through the filter screen into the device interior. In addition, the above sliding tube three, sliding tube two, sliding tube one and base tube are cylindrical. When the external wind flow contacts the outer wall of the above components, the airflow will flow along the outer wall of the above components, and two unequal pressure airflow differences will be formed at both ends of the cylindrical shape. The unequal airflow will produce regular oscillation on the side of the cylindrical assembly, and the airflow will carry most of the dust to flow synchronously. The position of the oscillation area close to the sliding tube three is a low flow area, and the dust content in this area is low. Through the application of the above components, the total amount of sand and dust entering the device interior is greatly reduced when the device is ventilated, and the quality of the internal lubricating oil is ensured.

[0017] (3) The application utilizes the feature that the distance between the sliding tube two and the sliding tube three will be shortened when the above pressure applying mechanism operates. A cleaning assembly and a sealing assembly are arranged inside the device. When the sliding tube three is pulled downward by the electric telescopic rod, the sliding tube three drives the annular sliding plate along the inner wall of the sliding plug ring groove to slide downward through the L-shaped arc plate. At the same time, the sliding tube three drives the annular box two and the piston plate to move downward through the installation ring. When the bottom of the pressure ring contacts the top of the sliding tube two, the annular box one will enter the sliding plug ring groove. As the electric telescopic rod contracts, the piston plate will move upward along the inner wall of the annular box two. The gas in the annular box two enters the rubber expansion tube through the annular box one, forcing the rubber expansion tube to expand inside the sliding plug ring groove. Through the application of the above components, the sealing performance of the above sealed space is improved, and the formation of internal high pressure is avoided because of the leakage phenomenon of the gap.

[0018] (4) When the pressure applying mechanism contracts, the installation ring will drive the limiting plate one to descend as the distance between the installation ring and the sliding tube one decreases. The sliding plate will enter the inner wall of the limiting plate two and the limiting plate one under the influence of the annular track. At this time, the limiting plate one and the limiting plate two will scratch and clean the outer wall of the sliding plate. During this process, the cleaning frame will clean the outer wall of the limiting plate two and the limiting plate one. Through the application of the above components, the dust remaining on the outer wall of the sliding plate, the limiting plate one and the limiting plate two is effectively removed, avoiding excessive dust remaining, increasing the weight of the guide assembly and affecting the rotation efficiency of the limiting plate one, the sliding plate and the limiting plate two.

At this time, the inside of the equipment is high-pressure and high-temperature gas, and the outside of the equipment is low-temperature gas.

When the external wind speed is fast, the wind flow will act on the side wall of the limiting plate one 61, the sliding plate 62 and the limiting plate two 63, forcing the above components to drive the installation ring 51 and the sliding tube three 34 to rotate around the sealing ring 23. At this time, the limiting plate one 61 is rotated by the wind, forcing the filter screen 35 to be in a position away from the wind, so as to avoid that the wind flow carrying dust directly passes through the filter screen 35 into the equipment interior; in addition, the above sliding tube three 34, sliding tube two 33, sliding tube one 32 and base tube 31 are cylindrical, when the external wind flow contacts the outer wall of the above components, the airflow will flow along the outer wall of the above components, and two unequal pressure airflow differences are formed at both ends of the cylindrical shape, and the unequal airflow will produce regular swing on the side of the cylindrical component, and the airflow will carry most of the dust to flow synchronously, and the swing area close to the position of the sliding tube three 34 is a low flow area, and the dust content of the air in this area is low. Through the application of the above components, the total amount of sand and dust entering the equipment interior is greatly reduced when the equipment is ventilated, and the quality of the internal lubricating oil is ensured. When the above pressure applying mechanism 3 operates, the distance between the sliding tube two 33 and the sliding tube three 34 will be shortened, and the equipment is provided with a cleaning assembly 4 and a sealing assembly 5 inside the equipment. When the sliding tube three 34 is pulled downward by the electric telescopic rod 11, the sliding tube three 34 drives the annular sliding plate 46 to slide downward along the inner wall of the sliding plug ring groove 41 through the L-shaped arc plate 45, and at the same time, the sliding tube three 34 drives the annular box two 54 and the piston plate 55 to move downward through the installation ring 51. When the bottom of the pressure ring 56 contacts the top of the sliding tube two 33, the annular box one 52 will enter the sliding plug ring groove 41, and as the electric telescopic rod 11 contracts, the piston plate 55 will move upward along the inner wall of the annular box two 54. The gas in the annular box two 54 enters the rubber expansion tube 53 inside the annular box one 52, forcing the rubber expansion tube 53 to expand inside the sliding plug ring groove 41. Through the application of the above components, the sealing performance of the above closed space is improved, and the formation of internal high pressure is avoided because of the gap.

[0045] When the pressing mechanism 3 is retracted, as the distance between the mounting ring 51 and the sliding tube 32 is reduced, the mounting ring 51 will drive the limiting plate one 61 to descend, and the limiting plate two 63 will be affected by the annular track 64, so that the sliding plate 62 will enter the limiting plate two 63 and the inner wall of the limiting plate one 61. At this time, the limiting plate one 61 and the limiting plate two 63 will scratch the outer wall of the sliding plate 62 for cleaning. During this process, the cleaning frame 65 will clean the outer wall of the limiting plate two 63 and the limiting plate one 61. Through the application of the above components, dust residues remaining on the outer wall of the sliding plate 62, the limiting plate one 61 and the limiting plate two 63 are effectively removed, so that the excessive dust residues are avoided, the weight of the guiding assembly 6 is reduced, and the rotation efficiency of the limiting plate one 61, the sliding plate 62 and the limiting plate two 63 is improved.
