Description

Technical Field

[0001] The present invention relates to the field of traffic technology, and in particular to a smart traffic capture system and method. Background Art

[0002] With the application and upgrading of smart transportation in smart cities, traffic congestion and traffic safety issues have also been alleviated accordingly. In the actual application of smart transportation, traffic management departments have set up traffic detection points along highways or major roads in cities for real-time monitoring. With the development of science and technology and the introduction of high-tech, intelligent video surveillance information, as the richest source of all information, has attracted widespread attention in the industry, and a large number of intelligent traffic monitoring systems have been established in various places, which can accurately capture illegal vehicles in real time, greatly improving traffic management efficiency.

[0003] However, most of the current traffic capture cameras are fixed structures, and their shooting angles are opposite to the direction of the road and are always fixed or rotated at a constant speed. Since the camera position is fixed and the shooting is at an angle, if the vehicle speed is fast, the angular velocity relative to the camera changes too quickly, the captured picture is easily deformed and blurred, and it is impossible to accurately judge whether the vehicle is driving in violation of regulations and it is difficult to accurately record vehicle information. Therefore, the present invention provides a smart traffic capture system and method, the shooting angle of the capture camera is opposite to the direction of vehicle travel on the road, and the capture camera is driven by a camera rotation drive component to swing back and forth downward to capture the moving vehicle. In this way, clear pictures can be taken to avoid omissions and errors in vehicle violations. When the capture camera rotates downward counterclockwise, the rotation angular velocity changes from slow to fast at a constant speed. After reaching the lower dead point, the capture camera quickly returns to the initial position and rotates downward counterclockwise again. In this way, accurate capture can be achieved to capture clear pictures to avoid omissions and errors in vehicle violations. Moreover, the entire device is a detachable installation structure, which is conducive to subsequent maintenance. Summary of the invention

A plurality of abutting rods are fixedly connected to the bottom end surface of the lifting plate.

[0009] The lower end of the abutting rod is rotatably connected with a roller.

[0010] Integrally connected circular convex plates are provided on the opposite side end surfaces of the end plates on the left and right sides. The left and right ends of the cylindrical column are respectively sleeved on the outer surfaces of the circular convex plates on the left and right sides. A metal sealing gasket is sleeved on the outer surface of the circular convex plate.

[0011] A plurality of columns are connected to the bottom inside the cylindrical column. A plurality of telescopic columns are connected between the upper ends of the columns and the lifting plate. The telescopic column includes a telescopic sleeve. The upper end of the telescopic sleeve is slidably penetrated with a telescopic column. A vacuum chamber is provided inside the telescopic sleeve. The telescopic sleeve is fixedly arranged on the column. The upper end of the telescopic column is fixedly connected to the bottom end surface of the lifting plate.

[0012] The contour line of the cam is arranged in a progressive spiral shell shape. The contour line of the cam includes a highest point b and a lowest point a. A right-angle fault is provided between the highest point b and the lowest point a.

[0013] A usage method of an intelligent transportation capture system includes the following steps:

[0014] S1: Install the connecting column on the top inside the cylindrical column, and horizontally penetrate the connecting rod through the connecting column;

[0015] S2: Install the motor and the guide rod in the camera rotation driving component below the connecting column inside the cylindrical column;

[0016] S3: Place the end plates connected to the left and right sides of the bottom end surface of the capture camera on the left and right sides of the cylindrical column. At this time, the outer connecting holes at the centers of the end plates correspond to the inner connecting holes at the left and right ends of the connecting rod. Connect the inner connecting holes and the outer connecting holes with bolts.

[0018] S5: When conducting illegal shooting through the capture camera, the motor drives the rotating rod and the cam on its outer surface to rotate. The contour line of the cam is set in a progressive spiral shell shape. In the initial state, the roller is at the lowest point a. At this time, the cam rotates clockwise. During the rotation process, the cam pushes the roller up. During this process, the roller always abuts against the contour line of the cam.

The roller, the abutting rod and the lifting plate connected to it are pushed up along the guide rod, and the rotating head connected to the lifting plate is pushed up. The rotating head is arranged to roll in the rectangular groove. Therefore, the rising rotating head can push the end plate to rotate, thereby realizing the rotation of the capture camera, and the angular velocity of rotation increases uniformly from slow to fast. From slow to fast, during this process, shooting operations can always be carried out through the capture camera;

[0019] S6: During the rotation process of the above capture camera, the lifting plate is pushed up. At this time, the telescopic column connected to the lifting plate is pulled out from the telescopic sleeve, and a vacuum chamber is arranged in the telescopic sleeve;

[0020] S7: When the roller moves to the highest point b of the cam and directly falls from the right-angle fault, at this time, under the action of atmospheric pressure, the telescopic column is pressed into the vacuum chamber in the telescopic sleeve, realizing the rapid fall of the lifting plate, thereby realizing the rapid rotation and reset of the capture camera. Driven by air pressure, it has a buffer and shock absorption effect.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] The present invention provides an intelligent transportation capture system and method. The shooting angle of the capture camera is opposite to the direction of vehicle travel on the road. The capture camera is pushed to swing downward reciprocally through the camera rotation driving component to shoot the oncoming vehicles. In this way, clear pictures can be taken, avoiding omissions and errors in the illegal driving of vehicles. When the capture camera rotates downward counterclockwise, the rotation angular velocity increases uniformly from slow to fast, adapting to the vehicle speed. After reaching the lower dead point, the capture camera quickly returns to the initial position, and when rotating downward counterclockwise again, in this way, accurate capture can be realized, clear pictures can be taken, avoiding omissions and errors in the illegal driving of vehicles, and the whole device is a detachable installation structure, which is beneficial for subsequent maintenance.

Specific implementation mode

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] Embodiment 1: Please refer to Figures 1 to 6 , an intelligent transportation capture system, including a mounting base 3, the upper end of the mounting base 3 is integrally connected with a rectangular base 2, the upper end of the rectangular base 2 is integrally connected with a fixed seat 1, the upper end of the fixed seat 1 is integrally connected with a cylindrical column 4, the left and right ends of the cylindrical column 4 are open, end plates 7 are connected to the left and right ends of the cylindrical column 4, capture cameras 5 are fixedly connected to the upper ends of the end plates 7 on both sides, and mounting holes are provided through the four corners of the mounting base 3;

[0032] A connecting column 9 is fixedly connected to the inner top of the cylindrical column 4. A connecting rod 10 is horizontally and rotatably penetrated through the connecting column 9. Inner connecting holes 11 are penetrated through the left and right ends of the connecting rod 10. Outer connecting holes 8 are penetrated through the centers of the end plates 7 on the left and right sides. The outer connecting holes 8 on the left and right sides and the inner connecting holes 11 are correspondingly connected by bolts 6. A camera rotation driving component 12 is connected and installed between the end plates 7 on the left and right sides.

[0033] In this embodiment, it includes a capture camera 5 for traffic vehicle capture. The end plates 7 connected thereto are installed at the left and right ends of the cylindrical column 4. The installation base 3 connected to the cylindrical column 4 is installed on the equipment pole for illegal shooting on the traffic road. At this time, the shooting angle of the capture camera 5 is opposite to the traveling direction of the road vehicles. By the camera rotation driving component 12, the capture camera 5 is pushed to swing downward reciprocally to shoot the traveling vehicles. In this way, clear pictures can be taken to avoid omission and error of illegal vehicle driving.

[0034] When the above-mentioned camera rotation driving component 12 pushes the capture camera 5 to rotate downward counterclockwise, the rotation angular velocity uniformly changes from slow to fast, adapting to the change from slow to fast between the angles of the uniform-speed vehicle from far to near and the camera (under the premise of constant speed, that is, the change rate of the angle between the vehicle in the distance and the camera per unit time is less than the change rate of the angle between the vehicle in the vicinity and the camera per unit time). After reaching the lower dead point, the capture camera 5 quickly returns to the initial position and rotates downward counterclockwise again. In this way, accurate capture is achieved.

[0035] Among them, the above-mentioned camera rotation driving component 12 includes a motor 124. A rotating rod 127 is fixedly connected to the output end of the motor 124. A plurality of cams 128 are fixedly sleeved on the outer surface of the rotating rod 127. A rectangular groove 14 is provided on the end plate 7. A rotating head 14 is arranged in the rectangular groove 14. A lifting plate 125 is connected between the rotating heads 14 on the left and right sides. The lifting plate 125 is rotatably connected to the rotating head 14. A plurality of guide rods 121 are vertically and slidably penetrated through the lifting plate 125. The upper and lower ends of the guide rods 121 are fixedly connected to the upper and lower side walls inside the cylindrical column 4. A plurality of abutting rods 120 are fixedly connected to the bottom end surface of the lifting plate 125. The lower end of the abutting rod 120 is rotatably connected to a roller 129.

[0036] A plurality of columns 122 are connected to the inner bottom of the above-mentioned cylindrical column 4. A plurality of telescopic columns 123 are connected between the upper ends of the columns 122 and the lifting plate 125. The telescopic column 123 includes a telescopic sleeve 1233. The upper end of the telescopic sleeve 1233 is slidably penetrated through a telescopic column 1232. A vacuum chamber 1231 is arranged in the telescopic sleeve 1233. The telescopic sleeve 1233 is fixedly arranged on the column 122. The upper end of the telescopic column 1232 is fixedly connected to the bottom end surface of the lifting plate 125.

[0037] It is worth mentioning that the contour line of the cam 128 in the camera rotation drive component 12 is arranged in a progressive spiral shell shape. The contour line of the cam 128 includes the highest point b and the lowest point a, and a right-angle fault is arranged between the highest point b and the lowest point a;

[0038] When the capture camera 5 is used for illegal shooting, the motor 124 drives the rotating rod 127 and the cam 128 on its outer surface to rotate. The contour line of the cam 128 is arranged in a progressive spiral shell shape. In the initial state, the roller 129 is located at the lowest point a. At this time, the cam 128 rotates clockwise. During the rotation process, the cam 128 pushes up the roller 129. During this process, the roller 129 is always in contact with the contour line of the cam 128. Because the contour line of the cam 128 is arranged in a progressive spiral shell shape, the rising speed of the roller 129 decreases uniformly. The roller 129 and the connecting abutting rod 120 and the lifting plate 125 are pushed up along the guide rod 121, and the rotating head 126 connected to the lifting plate 125 is pushed up. The rotating head 126 is arranged to roll in the rectangular groove 14. Therefore, the rising rotating head 126 can push the end plate 7 to rotate, so as to realize the rotation of the capture camera 5, and the angular velocity of rotation decreases uniformly, from fast to slow. During this process, the capture camera 5 can always perform shooting operations;

[0039] During the rotation of the capture camera 5 described above, the lifting plate 125 is pushed up. At this time, the telescopic column 1232 connected to the lifting plate 125 is pulled out from the telescopic sleeve 1233, and a vacuum chamber 1231 is arranged in the telescopic sleeve 1233;

[0040] When the roller 129 moves to the highest point b of the cam 128 and directly falls from the right-angle fault, at this time, under the action of the atmospheric pressure, the telescopic column 1232 is pressed into the vacuum chamber 1231 in the telescopic sleeve 1233, realizing the rapid fall of the lifting plate 125, so as to realize the rapid rotation and reset of the capture camera 5. Through pneumatic drive, it has a buffer and shock absorption effect.

[0041] Embodiment 2: Please refer to Figure 3 , a smart traffic capture system, which is different from Embodiment 1 in that circular convex plates 13 are integrally connected to the opposite side end faces of the left and right end plates 7. The left and right ends of the cylindrical column 4 are respectively sleeved on the outer surfaces of the left and right circular convex plates 13, and a metal sealing gasket is sleeved on the outer surface of the circular convex plate 13.

[0042] In this embodiment, the end plates 7 are installed at the left and right ends of the cylindrical column 4. The left and right ends of the cylindrical column 4 are sleeved on the outer surfaces of the circular convex plates 13, and a metal sealing gasket is sleeved on the outer surface of the circular convex plate 23, which has a waterproof effect and avoids water entering the cylindrical column 4 in the outdoor environment and causing equipment damage.

[0043] In summary, the present invention provides an intelligent transportation capture system and method. The shooting angle of the capture camera 5 is opposite to the traveling direction of road vehicles. The capture camera 5 is pushed to swing downward reciprocally by the camera rotation driving member 12 to capture the traveling vehicles. In this way, clear pictures can be captured, avoiding omission and error of vehicle illegal driving. When the capture camera 5 rotates counterclockwise downward, when the driving member rotates at a uniform speed, the angular velocity of the camera rotation can be made to increase uniformly from slow to fast. After reaching the lower dead point, the capture camera 5 quickly returns to the initial position and rotates counterclockwise downward again. In this way, precise capture can be achieved, clear pictures can be captured, avoiding omission and error of vehicle illegal driving, and the whole device is a detachable installation structure, which is beneficial to subsequent maintenance.

[0044] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
