DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-3 The utility model provides an implementation scheme: in the modern traffic video monitoring process, fixed-angle camera equipment is mainly used. This method is very reasonable at large intersections and main roads, but at some small intersections, the travel pattern of traffic is very fixed, and the direction of traffic often changes significantly according to the rush hour. For example, there are more cars in the north-south direction during rush hour and more cars in the east-west direction during off-get off work hours. Therefore, if fixed-angle cameras are used, many cameras need to be added for comprehensive coverage, which wastes public resources and increases the difficulty of maintenance work.

[0021] In order to solve the above problems, the present application discloses a smart traffic monitoring device, which is installed on the top of a roadside street lamp or a building through a fixed bracket 1 with an inverted L-shaped structure to play a role in fixing the position. A rotating seat 2 is provided on the fixed bracket 1. The rotating seat 2 is specifically used to install a video monitoring probe 3. The video monitoring probe 3 is installed on the rotating seat 2 through a rotating shaft 4. The rotating shaft 4 is movably connected to the rotating seat 2. The shooting angle of the video monitoring probe 3 can be adjusted by adjusting the angle of the rotating shaft 4.

[0022] Specifically, according to the instructions Figure 1-3 It can be seen that a dividing angle gear 5 is arranged at the top of the rotating shaft 4, a controller is arranged in the fixed bracket 1, a control motor 6 is connected to one side of the controller, a control rod 7 is connected to the driving end of the control motor 6, and the control rod 7 is meshed with the dividing angle gear 5 through a gear set;

[0023] In the specific implementation process, the angle adjustment of the video surveillance probe 3 is controlled by the control command issued by the controller. Through the built-in timing circuit of the controller, the traffic time period of the intersection is known according to the big data of the traffic department and the previous video surveillance data. When the timing circuit times to a certain point, according to the direction of the expected traffic flow change, the controller controls the control motor 6 to rotate, so that the control motor 6 drives the control rod 7 to rotate the corresponding number of circles and angles, and the gear set on the control rod 7 is engaged with the indexing angle gear 5 to rotate, so that the indexing angle gear 5 drives the rotating shaft 4 to rotate and adjust the horizontal angle of the video surveillance probe 3, so that it is monitored toward the side with more traffic;

[0024] Furthermore, a rotating plate 8 is provided at the top of the rotating shaft 4, an arc-shaped groove 9 is provided on the rotating seat 2, a pair of limit seats 10 are mounted on the arc-shaped groove 9, a pair of limit seats 10 are provided with a pair of limit switches 11, and a contact short column 12 is provided at the bottom of the rotating plate 8, the contact short column 12 is located at the radial outer end of the rotating plate 8, and the contact short column 12 corresponds to the position of the pair of limit switches 11;

[0025] While the rotating plate 8 is used as a limiting device for the rotating shaft 4, the contact short column 12 on the rotating plate 8 can cooperate with a pair of limit switches 11. The pair of limit switches 11 are connected to the controller. Since the rotating plate 8 and the rotating shaft 4 can move as a whole, the working trajectory of the contact short column 12 on the rotating plate 8 is an arc, and the arc groove 9 is opened on the movement arc of the contact short column 12. The position of the pair of limit switches 11 on the arc groove 9 can be adjusted by a pair of limit seats 10. When the contact short column 12 contacts and triggers the limit switch 11, the controller controls the control motor 6 to stop rotating. This can play a limiting role on the one hand, and then limit the monitoring range of the video surveillance probe 3 to avoid excessive movement of the video surveillance probe 3 or unclear monitoring range, and then manually set the imaging range of the monitoring video. On the one hand, the deployment is more flexible, and on the other hand, it can avoid excessive movement of the equipment and damage to the equipment during mechanical failure.

[0026] As a preferred solution, further, the rotating seat 2 is a rectangular structured plate, a rotating groove is opened on the rotating seat 2, the rotating shaft 4 passes through the rotating groove, and the rotating plate 8 is assembled on the top of the rotating shaft 4. Through the mutual limitation of the rotating plate 8 and the rotating groove, the rotating shaft 4 can be axially limited.

[0027] As a preferred solution, further, the indexing angle gear 5 is arranged at the top of the rotating shaft 4 and located on the upper part of the rotating plate 8. The indexing angle gear 5 contacts the top surface of the rotating plate 8. When the indexing angle gear 5 rotates, it synchronously drives the rotating plate 8 and the rotating shaft 4 to move.

[0028] As a preferred solution, further, the rotating seat 2 is fixed to the end of the fixed bracket 1 by screws, and the reinforcing ribs at the corners of the fixed bracket 1 play a role in strengthening the fixed bracket 1. The rotating seat 2 can be disassembled and assembled by screws.

[0029] As a preferred solution, further, the limit seat 10 is composed of a reverse pull positioning seat 101, and the reverse pull positioning seat 101 is a plate of a columnar structure. A limit screw 102 is arranged at the bottom of the reverse pull positioning seat 101, and the limit screw 102 passes through the arc groove 9. A reverse pull nut 103 is sleeved on the limit screw 102. The reverse pull positioning seat 101 contacts the upper wall surface of the arc groove 9, and the limit screw 102 passes through the arc groove 9 and cooperates with the reverse pull of the reverse pull nut 103, so as to fix the reverse pull positioning seat 101. Specifically, a limit switch 11 is arranged on the reverse pull positioning seat 101 to cooperate with the contact short column 12.

[0030] As a preferred solution, further, the diameter of the limiting screw 102 matches the arc groove 9 and the width of the limiting nut and the reverse pull positioning seat 101 is greater than the width of the arc groove 9, which plays a limiting role.

[0031] From the above, it can be generally known that the intelligent traffic monitoring device uses a video monitoring probe 3 to monitor passing vehicles. The video monitoring probe 3 is installed through a modular rotating seat 2 and a rotating shaft 4, which is convenient for assembly and disassembly. An angle adjustment structure controlled by a timing circuit and traffic data is provided in the rotating seat 2, which can adjust the monitoring angle of the video monitoring probe 3. The monitoring angle can be changed according to changes in the direction of traffic at different time periods, thereby improving the utilization rate of public resources and being more energy-saving and environmentally friendly.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
