[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

[0032] Please refer to Figures 1 - 3 , the present invention provides a technical solution: a road auxiliary monitoring device integrating radar and camera, including:

[0033] Support frame 1, on which a horizontal brace 11 is provided;

[0034] Sliding seat 2, which is slidably connected to the horizontal brace 11;

[0035] Sliding assembly, which includes an electric push rod 3 and a linking block 4. The electric push rod 3 is arranged in the installation cavity 111 inside the horizontal brace 11. The linking block 4 is fixedly installed on the piston rod of the electric push rod 3. A connecting arm is provided on the linking block 4, and the connecting arm extends out of the kidney-shaped hole 12 on the horizontal brace 11 and then connects to the sliding seat 2;

[0036] Radar 5, which is fixedly installed on the sliding seat 2;

[0037] Camera 6, which is fixedly installed on the sliding seat 2.

[0038] The horizontal brace 11 is rotatably installed on the support frame 1, which is convenient for rotating and adjusting the orientations of the radar 5 and the camera 6 on the sliding seat 2, controlling the coverage range, and ensuring the monitoring effect.

[0039] One end of the cross strut 11 is rotatably installed on the support frame 1 through a first rotating shaft. A first gear 112 is sleeved on the first rotating shaft. A driving motor 7 is arranged on the support frame 1. The output end of the driving motor 7 is connected with a second gear 71. The second gear 71 meshes with the first gear 112. The driving motor 7 drives the second gear 71 to rotate, driving the first gear 112 and the cross strut 11 to rotate, so as to precisely adjust the orientations of the radar 5 and the camera 6 and precisely adjust the monitoring coverage range.

[0040] The cross section of the cross strut 11 is circular. The driving motor 7 contacts the cross strut 11 and uses the driving motor 7 to support the cross strut 11 to prevent the cross strut 11 from deforming and becoming loose in installation.

[0041] The cross section of the sliding seat 2 is "U"-shaped. An arc-shaped hanging plate 21 is arranged on the back of the sliding seat 2. The arc-shaped hanging plate 21 fits the surface of the cross strut 11. The two flat plates on both sides of the sliding seat 2 are convenient for installing the radar 5 and the camera 6, and the arc-shaped hanging plate 21 is used to prevent the sliding seat 2 from detaching from the cross strut 11.

[0042] The shape of the linkage block 4 matches the cross section of the installation cavity 111 to ensure the smooth movement of the linkage block 4 and the sliding seat 2.

[0043] Working principle: When the road auxiliary monitoring device monitors a relatively wide road, such as a road with up to 8 lanes in both directions, for the camera 6 on the sliding seat 2 that can only monitor several lanes in one direction conventionally, by using the characteristic of the wide coverage range of the radar 5, the monitoring of 8 lanes in both directions is realized. The specific principle is as follows: During the monitoring process, the radar mixes the echo and the reference signal of the transmitted wave to obtain a difference frequency signal. By analyzing the difference frequency signal, the distance and azimuth of the target are obtained. The camera zooms in and magnifies, and the target is reviewed through the video, realizing the integration and fusion of the radar and the camera in the monitoring device. That is, after the target is identified by the radar, the camera is started to zoom in and magnify the picture to realize the review of the recognition result, effectively realizing the monitoring of road violations. To facilitate the adjustment of the positions of the radar 5 and the camera 6, the sliding seat 2 can reciprocally move along the axial direction of the cross strut 11 under the action of the electric push rod 3. The position adjustment of the sliding seat 2 can also be used for the image acquisition during the camera review to ensure the monitoring effect.

[0044] Embodiment 2

[0045] On the basis of the above embodiment, this embodiment further makes the following improved technical solutions: The camera 6 is a binocular camera.

[0046] When using a binocular camera for image acquisition, it acts as an electric police in the forward direction and a checkpoint in the reverse direction, effectively improving the image acquisition effect and the monitoring quality.

[0047] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, making equivalent substitutions or changes, shall be covered by the protection scope of the present utility model.
