[0022] The following will be combined with the 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 part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Example 1

[0024] like Figures 1 to 4 As shown;

[0025] A radar-based vehicle type measurement device includes a support frame 1, a top plate 2 is fixed to the top of the support frame 1, and symmetrically arranged vehicle detection components 3 are installed on both sides of the bottom surface of the top plate 2. The vehicle detection component 3 includes a shell 31, which is fixed to the top plate 2 through a connecting frame 32 on the top. A tilted detection window 33 is provided on one side of the shell 31, and a radar module 34 is installed in the shell 31 at a position corresponding to the detection window 33. A discharge port 21 is provided in the middle of the top plate 2, and loading detection radars 4 fixed to the top plate 2 are provided on both sides of the discharge port 21.

[0026] In this embodiment: when a vehicle enters the present invention, the detection intervals of the radar modules 34 in the two symmetrically arranged vehicle detection components 3 are staggered to form a detection interval A, and the detection interval A covers the area below the top plate 2. When the vehicle enters the detection interval A, the vehicle license plate is scanned and recorded by the vehicle detection component 3 in the front direction of the vehicle. The vehicle compartment needs to be parked below the unloading port 21. The detection interval A can be used to know whether the vehicle is in the correct position. After the vehicle stops, the detection intervals of the loading detection radars 4 on both sides of the unloading port 21 are staggered to form a detection interval B, and the detection interval B covers the area below the unloading port 21. The two loading detection radars 4 scan the interior of the compartment to know whether there is residual material in the vehicle. During loading operations, the loading detection radar 4 scans the compartment in real time. Since materials are easily formed into a mound when poured into the compartment, which affects the loading capacity of the compartment, through real-time scanning, when a mound is formed, the inclination angle of the discharge port is changed to make the material loading more uniform.

[0027] It should be noted that: the utility model scans and detects passing vehicles through two symmetrically arranged vehicle detection components 3. During the detection, the entire vehicle is scanned by the radar module 34. The laser radar in the radar module 34 detects the position of the vehicle when it stops, the position of the front fender, the position of the rear of the vehicle, the relative position with the discharge port, and the length and width of the vehicle, so as to determine whether the vehicle is in the correct position when loading. In conjunction with the camera in the radar module 34, the vehicle is photographed, the model and license plate information is recorded, and it is monitored through a remote terminal. When loading operations are carried out, the loading detection radar 4 is also a laser radar that can scan the interior of the car to determine whether it is in an empty state when loading. Overloading can be avoided through real-time detection.

[0028] More specifically:

[0029] In an optional embodiment, an electronic truck scale 5 is provided on the ground below the top plate 2 .

[0030] In this embodiment: through this design, when a vehicle enters the present invention, it stops on the electronic truck scale 5, and the electronic truck scale 5 weighs the entire vehicle. By comparing the weighing results before and after material loading, the weight of the material loaded on the vehicle can be known, which is convenient for controlling the weight of the truck and avoiding overloading and overweight.

[0031] Going further:

[0032] In an optional embodiment, a wireless module 35 is installed on the top of the interior of the housing 31 , and the wireless module 35 is connected to an external control terminal.

[0033] In this embodiment: Through this design, the wireless module 35 of the present invention enables the data of the radar module 34 to be wirelessly transmitted to the external control terminal, and the wireless module 35 is arranged on the top of the shell 31. The shell 31 protects the wireless module 35 to prevent the wireless module 35 from being affected by external rainy weather, thereby improving the reliability of the present invention.

[0034] Going further:

[0035] In an optional embodiment, a heat dissipation grille 36 is provided on the bottom side of the housing 31 .

[0036] In this embodiment: through this design, the heat dissipation grille 36 improves the heat dissipation of the shell 31. The heat dissipation grille 36 is on the bottom side of the shell 31, which can prevent external dust, sand and other debris from falling into the shell 31. A mesh can also be set on the heat dissipation grille 36 to further improve the dust-proof effect.

[0037] Going further:

[0038] In an optional embodiment, a cement pier is provided at the bottom of the support frame 1 .

[0039] In this embodiment: through this design, the height of the support frame 1 of the utility model can be adjusted according to the working environment and the working vehicle type. By setting cement piers of different heights, the height adjustment of the support frame 1 is achieved. The structure is simple and the operation is convenient.

[0040] Going further:

[0041] In an optional embodiment, a display screen 11 is installed on the outer side wall of the support frame 1 .

[0042] In this embodiment: through this design, the display screen 11 can issue prompts to the driver, reminding the driver to drive the vehicle to the correct position. At the same time, the vehicle weight information and the cargo capacity information of the vehicle compartment can be displayed on the display screen 11, making it convenient for the driver to know the loading status of the vehicle compartment.

[0043] Going further:

[0044] In an optional embodiment, the radar module 34 includes a lidar and a camera.

[0045] In this embodiment: through this design, the laser radar in the radar module 34 scans the car compartment, and the camera photographs the car compartment. The combination of the two avoids a single detection method and improves the accuracy of detection. The camera in the radar module 34 is set on the top of the laser radar and is staggered with the laser radar in front and behind to avoid the laser radar damaging the light-sensing components in the camera.

[0046] The working principle and use process of the present invention: When a vehicle enters the present invention, the detection intervals of the radar modules 34 in the two symmetrically arranged vehicle detection components 3 are staggered to form a detection interval A, and the detection interval A covers the area below the top plate 2. When the vehicle enters the detection interval A, the vehicle detection component 3 in the direction of the vehicle head is used to scan and record the vehicle license plate. The vehicle compartment needs to be parked below the unloading port 21. The detection interval A can be used to know whether the vehicle is in the correct position. After the vehicle stops, the detection intervals of the loading detection radars 4 on both sides of the unloading port 21 are staggered to form a detection interval B. The detection interval B covers the area below the unloading port 21. The two loading detection radars 4 scan the interior of the compartment to know whether there is anything in the vehicle. Residual materials, when the vehicle enters the utility model, it stops on the electronic truck scale 5, and the electronic truck scale 5 weighs the entire vehicle. By comparing the weighing results before and after the material is loaded, the weight of the material loaded on the vehicle can be known, which is convenient for controlling the weight of the truck and avoiding overloading and overweight. When loading operations are carried out, the loading detection radar 4 scans the carriage in real time. Since the material is easily formed into a mound when poured into the carriage, which affects the loading capacity of the carriage, through real-time scanning, when a mound is formed, the inclination angle of the discharge port is changed, the material can be loaded more evenly, and the display screen 11 can issue a prompt to the driver, reminding the driver to drive the vehicle to the correct position. At the same time, the vehicle weight information and the carriage cargo capacity information can be displayed on the display screen 11, which is convenient for the driver to know the loading status of the carriage.
