[0023] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making any creative efforts shall fall within the scope of protection of the present invention.

[0024] In the description of this utility model, it should be noted that, unless otherwise specified or limited, the term "and / or" herein is merely a description of an association relationship between associated objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, and B exists alone. Furthermore, the character " / " herein, unless otherwise specified, generally indicates that the associated objects are in an "or" relationship.

[0025] Existing integrated traffic radars and vision systems typically only have a single front-facing camera, which monitors targets within a certain angle ahead. Consequently, these systems only monitor a limited area ahead, failing to achieve wide-area monitoring and resulting in targets in blind spots being undetectable.

[0026] In order to solve the above problems, the present invention provides a traffic monitoring radar device, which can reduce or eliminate the monitoring blind spots of the camera of the radar-visual integrated machine, so that the radar-visual integrated machine can also monitor targets in the blind spots.

[0027] See also Figure 1 and Figure 2 The traffic monitoring radar device provided by the embodiment of the present invention includes: a shell 1, a radar 2, a monitoring camera 3 and a monitoring component 4; the radar 2 and the monitoring camera 3 are arranged in the shell 1, and the detection direction of the radar 2 is the same as the monitoring direction of the monitoring camera 3; the monitoring component 4 is arranged in the shell 1, and is used to monitor in a predetermined direction, and the predetermined direction is inconsistent with the monitoring direction of the monitoring camera 3.

[0028] The monitoring component 4 of this embodiment can monitor in a predetermined direction, which is inconsistent with the monitoring direction of the surveillance camera 3. This enables the traffic monitoring radar device provided by this embodiment to use the monitoring component 4 to monitor areas that cannot be monitored by the camera of the radar-visual integrated machine, reducing or eliminating the monitoring blind spots of the camera of the radar-visual integrated machine, so that the radar-visual integrated machine can also monitor targets in the blind spots.

[0029] In one embodiment, the monitoring component 4 is a fisheye camera 41, and the predetermined direction monitored by the fisheye camera 41 is different from the monitoring direction of the surveillance camera 3, and the detection area of the fisheye camera 41 and the monitoring range of the surveillance camera 3 have at most partial overlap, and the monitoring azimuth angle of the fisheye camera 41 is 160°.

[0030] In this embodiment, since the fisheye camera 41 has a panoramic monitoring angle and a wide coverage range, it can fully fill the problem of the limited monitoring angle of view of the surveillance camera 3, and the monitoring range of the fisheye camera and the monitoring range of the surveillance camera 3 at most partially overlap, so that the fisheye camera 41 can monitor positions that the surveillance camera 3 cannot monitor. In addition, in this embodiment, the fisheye camera 41 is located below the shell 1. For example, the radar 2 and the surveillance camera 3 can monitor the situation in front of the shell 1, and the fisheye camera 41 is located below the shell 1 and can monitor the situation below the shell 1. The road below the shell 1 is the monitoring blind spot of the surveillance camera 3, so the fisheye camera 41 can be used to fill this monitoring blind spot.

[0031] In other embodiments, the monitoring component 4 can also be another set of monitoring cameras 3 and radars 2. Another set of monitoring cameras 3 and radars 2 are used to monitor the monitoring blind spots of the first set of radars 2 and monitoring cameras 3, and the radar-vision integrated system can also monitor targets in the blind spots.

[0032] In one embodiment, the shell 1 is provided with a mounting groove 11, and the fisheye camera 41 is accommodated in the mounting groove 11; the traffic monitoring radar device also includes a camera cover 12, which is arranged on the shell 1 and accommodated in the mounting groove 11 to cover the fisheye camera 41.

[0033] In this embodiment, by accommodating the fisheye camera 41 in the mounting groove 11, the fisheye camera 41 does not protrude from the housing 1, thereby providing a certain degree of protection for the fisheye camera 41. The installation of the camera cover 12 further protects the fisheye camera 41, thereby reducing the risk of damage to the fisheye camera 41.

[0034] In one embodiment, the traffic monitoring radar device further includes a first sealing ring 13 , which is disposed between the camera cover 12 and the inner wall of the mounting groove 11 .

[0035] In this embodiment, the use of the first sealing ring 13 can play a sealing role, and will not allow dust, rainwater, etc. to enter the installation groove 11 from between the camera cover 12 and the inner wall of the installation groove 11 to affect the use of the fisheye camera 41.

[0036] In one embodiment, the traffic monitoring radar device also includes a sealing cover 14, which is provided with a through hole that is compatible with the camera cover 12, and the camera cover 12 is assembled with the camera cover 12 through the through hole. The sealing cover 14 is arranged on the shell 1 and is fixedly assembled with the shell 1 through a fixing component 15.

[0037] Since the camera cover 12 is transparent, it cannot affect the use of the fisheye camera 41. If the camera cover 12 is directly fixed to the shell 1 using glue, nails, etc., it will inevitably affect the transparent effect of the camera cover 12. However, by assembling the camera cover 12 with the sealing cover 14, the camera cover 12 can be fixed to the shell 1 without affecting the transparent effect of the camera cover 12.

[0038] In one embodiment, the thickness of the camera cover 12 is greater than the thickness of the sealing cover 14 , and one side of the camera cover 12 in the thickness direction is assembled with the sealing cover 14 , and the other side is accommodated in the mounting groove 11 .

[0039] In this embodiment, the thickness of the camera cover 12 is greater than the thickness of the sealing cover 14 so that one side of the camera cover 12 in the thickness direction can be assembled with the sealing cover 14, and the other side can be accommodated in the mounting groove 11. The camera cover 12 and the sealing cover 14 arranged in this way have better sealing and protection effects. In this embodiment, the side of the camera cover 12 assembled with the sealing cover 14 is flush with the sealing cover 14, or the height of the camera cover 12 in the thickness direction of the camera cover 12 is lower than the height of the sealing cover 14. Such an arrangement can enable the external force to be shared by the sealing cover 14 when the camera cover 12 is subjected to external force, thereby also protecting the camera cover 12.

[0040] In one embodiment, the fixing component 15 is a locking screw, which is simple and easy to use. It is convenient to use the locking screw to lock the sealing cover 14. In other embodiments, the fixing component 15 can also be glue, a snap-fit structure, etc.

[0041] In one embodiment, the sealing cover 14 is rectangular, and each corner of the rectangle is rounded. The fixing components 15 are disposed at the four corners of the rectangular sealing cover 14 .

[0042] In this embodiment, in order to make the sealing cover 14 bear force more evenly, the shape of the sealing cover 14 is a special rectangle, that is, a square, and each corner is rounded to improve the force-bearing capacity at the angle. By setting fixing components 15 at all four corners, the stability of the sealing cover 14 installed on the shell 1 can be improved.

[0043] In one embodiment, the housing 1 includes a mounting shell 16 and a radome 17 , and a second sealing ring 18 is provided between the mounting shell 16 and the radome 17 .

[0044] By providing the second sealing ring 18 , the sealing performance of the housing 1 can be improved, thereby preventing rainwater and the like from entering the housing 1 .

[0045] Therefore, the traffic monitoring radar device provided by the present invention adds a new structural position under the radar 2 for installing the fisheye camera 41. The fisheye camera 41 is integrated with the shell 1. The camera cover 12 and the sealing cover 14 are connected to the outside of the fisheye camera 41, and are connected to the shell 1 through a sealing ring. The fixing screws are tightened to achieve sealing of the fisheye camera 41. At the same time, the antenna cover 17 and the shell 1 are pressed by the sealing ring to achieve sealing. The overall structure meets the IP67 waterproof requirements, and the camera can monitor targets within a long distance range of 160° in azimuth angle.

[0046] In addition, the fisheye camera 41 has a simple installation structure, and its waterproof sealing meets IP67. It can be installed outdoors without being affected by weather. At the same time, it solves the problem of target monitoring within the blind spot range, has a larger monitoring range, and achieves the monitoring effect of the original two or more radars 2. At the same time, it reduces the overall configuration cost, realizes multiple uses of one machine, and has better monitoring effect.

[0047] In summary, although the present invention has been disclosed above with reference to preferred embodiments, the above preferred embodiments are not intended to limit the present invention. A person skilled in the art may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be based on the scope defined by the claims.
