Description

Technical Field

[0001] The utility model relates to a radar sensor, in particular to a millimeter wave radar vehicle detector. Background Art

[0002] The toll island's barrier operation is accomplished by using a high-definition camera to capture the license plates of vehicles entering the toll island. After capturing the image, the barrier is controlled to allow the vehicle to pass. When the vehicle passes, the barrier is lowered. However, the HD camera only captures the license plates of vehicles within its monitoring range, so vehicles need to pass through at a low speed to ensure that the license plates can be clearly captured by the HD camera and then recognized by the system. Since the system will quickly identify the image when a vehicle enters the HD camera's monitoring range, and the huge amount of data processing, it may happen that the license plates cannot be clearly captured by the HD camera after a long period of operation. However, if a restriction is added, when a vehicle enters the toll island and is about to enter the shooting area, the HD camera will be prompted to prepare to capture the passing vehicle, which can greatly reduce the occurrence of this situation.

[0025] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0026] like Figure 1-4 As shown, a millimeter-wave radar vehicle detector is installed on the side wall of the toll island entrance and exit, comprising a panel 1 with a slot plate 2 fixed on the back, a plate antenna 11 fixed on the panel 1 and a sensor 12 located above the plate antenna 11;

[0027] A heat dissipation vest 8 is fixedly mounted on the slot plate 2 , and the heat dissipation vest 8 covers the circuit board 3 fixedly mounted on the slot plate 2 , and the sensor 12 is data-connected with the circuit board 3 .

[0028] Specifically, the sensor 12 in the embodiment is any one of a radar sensor, a space sensor and an ultrasonic sensor. Figure 1 As shown, a power light and a fault light are provided on both sides of the sensor 12. When the fault light is on, it means that there is a problem with the triggering radar, or it cannot be connected to the terminal through the local area network, or the sensor 12 data cannot be obtained by the circuit board 3. When the power light is on, it means that the mains power supply is in operation.

[0029] Secondly, the panel 1 in this embodiment is inlaid with a copper plate 4 positioned below the plate antenna 11. The entire panel 1 is also made of stainless steel. Therefore, when heat from the circuit board 3 is absorbed by the heat sink 8, it quickly diffuses into the slot plate 2 and is then absorbed by the copper plate 4, dissipating the heat. Furthermore, the stainless steel plate itself is thermally conductive.

[0030] In the above technology, a trigger radar is installed on the side wall of the toll island. When a vehicle passes by, it will detect the vehicle passing by. When it is about to enter the range that is most easily captured by the high-definition camera, the high-definition camera will be prompted to capture the image, thereby reducing the system's pressure on data processing and ensuring the timeliness of data processing, thereby reducing the occurrence of the situation where the license plate cannot be clearly captured by the high-definition camera during long-term operation.

[0031] As an embodiment further provided by the present invention, a power supply module and a WiFi transmission module are integrated on the circuit board 3 .

[0032] Specifically, the power supply module is a battery, and the WiFi transmission module is connected to the integrated barrier machine network on the toll island.

[0033] It should be noted that the above-mentioned electronic components and control programs are common technical knowledge to those skilled in the art, and therefore will not be described in detail.

[0034] As another embodiment further provided by the present invention, the trigger radar in this embodiment is installed by embedding, so it is necessary to cut a mounting groove of predetermined specifications on the side wall of the toll island, and then insert the groove plate 2 until the panel 1 is also embedded in the mounting groove port.

[0035] Further, combined Figure 1 As can be seen, a cross arm 21 is fixedly mounted on the end of the channel plate 2. Annular grooves 22 are defined on the cross arm 21 and three adjacent side surfaces of the channel plate 2. A rectangular frame 5 slides within the annular groove 22. Sliding grooves 23 are symmetrically defined within the annular groove 22. A cross beam 51 fixed to the inner wall of the rectangular frame 5 is positioned within the sliding grooves 23 for radial movement and is threadedly connected to the hexagonal screw 6. Therefore, when the hexagonal screw 6 is rotated, the rectangular frame 5 is easily moved closer to the panel 1.

[0036] Secondly, combined Figure 2 and Figure 3 As shown, an elastic member 7 is provided in the annular groove 22 and is distributed close to the panel 1 and abuts against the rectangular frame 5. The elastic member 7 includes an arc-shaped top 71, on which a hard rubber member 9 with linear array stripes is fixed.

[0037] Therefore, when the rectangular frame 5 moves close to the panel 1, the arc-shaped top 71 will be squeezed and deformed, thereby bulging outward, and then the arc-shaped top 71 will come into contact with the side wall of the installation groove and deform under the force, thereby causing the hard rubber part 9 to be squeezed and deformed, thereby achieving fixation and sealing, thereby preventing external water from entering the interior of the slot plate 2 through the gap between the installation groove and the trigger radar.

[0038] As another embodiment further provided by the present invention, the cross-section of the elastic member 7 is an R-shaped structure. The R-shaped structure is divided into an arc-shaped top 71, a vertical portion 72, and an inclined portion 73. The vertical portion 72 is fixed to the side wall of the annular groove 22, while the end of the inclined portion 73 contacts the rectangular frame 5. The inclined portion 73 has a chamfered groove 731 distributed adjacent to the end.

[0039] Specifically, in the embodiment, when the rectangular frame 5 moves close to the panel 1, it pushes the inclined portion 73 close to the panel 1. At this time, the chamfered groove 731 bends and deforms, thereby applying an outward force to the end connecting the arc top 71 and the inclined portion 73, thereby further increasing the force acting on the arc top 71 due to the deformation caused by the movement of the rectangular frame 5 pushing the inclined portion 73 to move, thereby further ensuring the fixing effect and sealing.

[0040] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
