Description

Technical Field

[0001] This utility model relates to the field of traffic detection equipment technology, specifically a front-end dynamic traffic information collection device. Background Technology

[0002] Front-end dynamic traffic information collection is a crucial component of intelligent transportation systems. Multi-target tracking radar technology, in traffic situational awareness, uses radar event detectors to perceive vehicle status data, such as multi-target radar vehicle detectors. By controlling the direction and shape of the radar beam, it achieves precise detection of multiple targets. Installed at traffic targets, it detects pedestrians, non-motorized vehicles, and motorized vehicles. It uses microwave or radar technology to transmit signals to the road surface, and determines the presence, type, and speed of vehicles based on the time difference or intensity changes of the reflected signals. This method is unaffected by weather and is easy to install and maintain.

[0003] Depending on the specific application scenarios and needs of traffic roads, such as installation on a gantry spanning the road (which provides a longer detection range and covers multiple lanes), or installation on traffic signal poles, existing devices are inconvenient to adjust for specific application scenarios and needs during installation, requiring multiple structural configurations. To address these issues, a front-end dynamic traffic information collection device is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a front-end dynamic traffic information collection device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A front-end dynamic traffic information collection device includes a multi-target radar vehicle detector; an installation mechanism including a mounting plate and a plurality of clamping bars disposed on the side of the mounting plate away from the multi-target radar vehicle detector, wherein the ends of the clamping bars are connected to sliders, the mounting plate is provided with a sliding groove for sliding the sliders, and a fixing member for fixing the sliding position of the sliders is mounted on the mounting plate.

[0007] A mounting base is fixedly connected to the side of the mounting plate near the multi-target radar vehicle detector, and a Y-axis rotating bracket is rotatably connected to the mounting base;

[0008] A Z-axis rotating frame is fixedly connected to one side of the Y-axis rotating frame; a rotating block rotatably connected to the Z-axis rotating frame is installed on one side of the multi-target radar vehicle detector; and

[0009] Locking devices installed on the Y-axis rotating frame and the Z-axis rotating frame are used to limit the rotation of the Y-axis rotating frame on the mounting base or the rotation of the rotating block on the Z-axis rotating frame.

[0017] This invention, based on specific application scenarios and needs of traffic roads, allows for installation on gantry frames or other horizontally arranged poles such as square poles. The positions of the upper and lower sets of clamping bars can be adjusted to ensure contact between the clamping bars and the target installation position, thus securing the device. When installed on traffic light poles or other vertically arranged poles, the two sets of clamping bars at the same horizontal position can clamp and fix the device. The mounting plate is attached to one side of the pole, providing a hugging installation, facilitating easy operation and installation, and allowing for flexible adjustment according to installation requirements. Simultaneously, the multi-target radar vehicle detector can be angled around the Y-axis or Z-axis, allowing it to adjust to a suitable detection angle based on road shape and traffic flow to cover multiple lanes or target areas. This facilitates the collection of dynamic traffic information at the front end and allows for convenient viewing of the collected information at the back end. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figures 1-5In this embodiment, a front-end dynamic traffic information collection device includes a multi-target radar vehicle detector 1 and a mounting mechanism 2, which includes a mounting plate 21 and a plurality of clamping strips 22 disposed on the side of the mounting plate 21 away from the multi-target radar vehicle detector 1. The ends of the clamping strips 22 are connected to sliders 23. The mounting plate 21 is provided with a sliding groove 24 for sliding the slider 23. A fixing member for fixing the sliding position of the slider 23 is installed on the mounting plate 21.

[0031] A mounting base 3 is fixedly connected to the mounting plate 21 on the side near the multi-target radar vehicle detector 1, and a Y-axis rotating frame 4 is rotatably connected to the mounting base 3;

[0032] A Z-axis rotating frame 5 is fixedly connected to one side of the Y-axis rotating frame 4; a rotating block 6, rotatably connected to the Z-axis rotating frame 5, is installed on one side of the multi-target radar vehicle detector 1; and

[0033] The locking element 7 installed on the Y-axis rotating frame 4 and the Z-axis rotating frame 5 is used to limit the rotation of the Y-axis rotating frame 4 on the mounting base 3 or the rotation of the rotating block 6 on the Z-axis rotating frame 5.

[0034] Using the above solution, depending on the specific application scenario and needs of the traffic road, the positions of the upper and lower sets of clamping bars 22 can be adjusted on the horizontally arranged poles such as gantry frames or square poles, so that the clamping bars 22 contact the target installation position. The clamping bars 22 are then connected to the target installation position using corresponding screws, bolts or other existing fastening components. The mounting plate 21 is then placed against one side of the target installation position to complete the fixation of the device.

[0035] The multi-target radar vehicle detector 1 can be angled around the Y-axis or Z-axis, so that the multi-target radar vehicle detector 1 can be adjusted to a suitable detection angle according to the road shape and traffic flow to cover multiple lanes or target areas, which is conducive to the collection of dynamic traffic information at the front end and facilitates the viewing of the collected information at the back end.

[0036] Installed on traffic signal poles or other vertically installed poles, two sets of clamping strips 22 at the same horizontal position can be clamped and fixed. There is a distance between the clamping strips 22 and the pole, and other existing accessories such as pads or rubber pads can be added. The mounting plate 21 is attached to one side of the pole and is installed on the pole in a hugging manner. The clamping strips 22 are connected to the target installation position using screws, bolts or other existing fastening components.

[0037] like Figure 4As shown, the fixing component includes a positioning bolt 25 threaded to the outer wall of the mounting plate 21, and the slider 23 is provided with a threaded hole that engages with the positioning bolt 25. The outer wall of the mounting plate 21 is provided with a plurality of positioning holes 26 that engage with the positioning bolt 25. The position of the slider 23 in the slide groove 24 is adjusted, and then the positioning bolt 25 is screwed into the corresponding positioning hole 26 and placed into the threaded hole to fix the position of the slider 23.

[0038] like Figure 2 As shown, the mounting plate 21 has an arc-shaped surface a27 on the side away from the mounting base 3, and the slider 23 has an arc-shaped surface b28 on one side. The slider 23 has a number of mounting holes that pass through laterally and vertically.

[0039] like Figure 2 and Figure 5 As shown, the locking member 7 includes a locking head 71 and a locking screw 72 fixedly connected to the bottom of the locking head 71. The bottom of the locking head 71 is rotatably connected to a movable ring 73. A limiting rod 74 is fixedly connected to the outer wall of the movable ring 73. The movable ring 73 is provided with a through hole for the locking screw 72 to pass through.

[0040] Rotating the locking head 71 allows the locking screw 72 to rotate. When the locking head 71 is rotated away from the mounting base 3 or the rotating block 6, it is convenient to adjust the rotation of the Y-axis rotating bracket 4 or the rotating block 6.

[0041] like Figure 3 As shown, both the mounting base 3 and the rotating block 6 are provided with locking screw holes that are threadedly engaged with the locking screw 72. The top of the Y-axis rotating frame 4 and one side of the Z-axis rotating frame 5 are provided with arc-shaped slots for the movement of the movable ring 73. With the arc-shaped slots provided, the locking screw 72 and the movable ring 73 do not affect the rotation of the Y-axis rotating frame 4 or the rotating block 6.

[0042] like Figure 3 As shown, the top of the Y-axis rotating frame 4 is provided with several first positioning grooves 41 that engage with the limiting rod 74; when the Y-axis rotating frame 4 needs to be fixed, the locking head 71 is rotated down to make the limiting rod 74 engage in the corresponding first positioning groove 41, thereby restricting the rotation of the Y-axis rotating frame 4.

[0043] like Figure 3 As shown, the Z-axis rotating frame 5 has several second positioning grooves 51 on its outside that engage with the limiting rod 74; the rotating locking head 71 moves to the side closer to the rotating block 6, so that the limiting rod 74 engages in the corresponding second positioning groove 51, thereby restricting the rotation of the rotating block 6.

[0044] The working principle of this utility model is as follows: According to the specific application scenario and needs of traffic roads, the positions of the upper and lower sets of clamping bars 22 can be adjusted on the horizontally arranged rods such as gantry frames or square bars, and the position of the slider 23 in the slide groove 24 can be adjusted. Then, the positioning bolt 25 is screwed into the corresponding positioning hole 26 and placed into the screw hole to fix the position of the slider 23, so that the clamping bar 22 contacts the target installation position. The clamping bar 22 is connected to the target installation position using the corresponding screws, bolts or other existing fastening parts. The mounting plate 21 is attached to one side of the target installation position to complete the fixation of the device.

[0045] The multi-target radar vehicle detector 1 can be angled around the Y-axis or Z-axis, so that the multi-target radar vehicle detector 1 can be adjusted to a suitable detection angle according to the road shape and traffic flow to cover multiple lanes or target areas, which is conducive to the collection of dynamic traffic information at the front end and facilitates the viewing of the collected information at the back end.

[0046] Installed on traffic light poles or other vertically installed poles, two sets of clamping strips 22 at the same horizontal position can be clamped and fixed. The mounting plate 21 is attached to one side of the pole and is installed on the pole in a hugging manner. The clamping strips 22 are connected to the target installation position using screws, bolts or other existing fastening components.

[0047] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
