[0023] To make the objectives, technical solutions, and advantages of one or more embodiments of this specification clearer, the technical solutions of one or more embodiments of this specification will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this specification, and not all of them. Based on the embodiments in this specification, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of one or more embodiments of this specification.

[0024] The technical solutions provided in the various embodiments of this specification are described in detail below with reference to the accompanying drawings.

[0025] To address the shortcomings of existing technologies, this solution provides the following embodiments:

[0026] The mobile transport vehicle detection system provided in the embodiments of the specification will be described in detail with reference to the accompanying drawings.

[0027] The mobile transport vehicle detection system described in this specification may include:

[0028] Multiple weighing platforms are detachably installed on the ground in the detection area and arranged sequentially at a preset distance along a preset direction; when the wheels of the transport vehicle are on all of the weighing platforms, the weight information of the transport vehicle is collected.

[0029] A radar detection system is installed within the detection area, including a movable first support component and a lidar 4 located at the top of the first support component; when the lidar 4 receives a first detection signal that the transport vehicle has entered the detection area, the lidar 4 collects the size information of the transport vehicle.

[0030] In the embodiments described in this specification, the mobile transport vehicle detection system may include a weighing platform and a radar detection system, both located within a detection area. The detection area is a specific space established to meet vehicle detection needs, equipped with the necessary detection equipment and instruments to perform comprehensive detection and analysis of transport vehicles. In application, the detection area can be deployed at locations such as highway service areas and checkpoints.

[0031] Weighing platforms are used to measure the weight of transport vehicles. By arranging multiple weighing platforms sequentially on the ground of the inspection area according to a preset direction and distance, it can be ensured that the wheels of a transport vehicle can land on all the weighing platforms as it passes over them, thereby collecting the vehicle's weight information. The detachable design of the weighing platforms facilitates their movement or maintenance when needed. To ensure better vehicle loading onto the weighing platforms, the preset direction of the weighing platforms is perpendicular to the direction in which the transport vehicle enters the inspection area, and the center distance between each weighing platform is adjusted to match the center distance of the average wheel track on each axle of the transport vehicle.

[0032] In practical applications, a flat, solid road surface free of gravel particles should be selected, and wireless weighing platforms should be placed. The distance and position between each weighing platform should be adjusted to ensure measurement accuracy. The weighing platforms can be wireless, and there can be four platforms in total. The four platforms are divided into pairs, with one side of the vehicle's wheels driving over one pair. To ensure accurate measurement of the vehicle's weight, both sides of the front axle simultaneously drive over all four platforms. After the front axle passes, both sides of the rear axle also simultaneously drive over all four platforms, thus completing the collection of the transport vehicle's weight information. The preferred dimensions for each weighing platform are 800mm × 450mm × 30mm.

[0033] The first support assembly supports the lidar 4, which is located at the top of the first support assembly and is used for detection and data acquisition. When the lidar 4 receives the first detection signal that a transport vehicle has entered the detection area, the laser inside the lidar 4 emits a light pulse. After the laser shines on the target object, it produces diffuse reflection. The photoelectric sensor inside the lidar 4 receives the diffusely reflected light, and the lidar 4 measures the flight time of the laser pulse from emission to reception to calculate the distance from the target object to the lidar 4. For example, if the target object is a transport vehicle and the lidar 4 is a Scope128H lidar, the size information of the transport vehicle can be calculated based on the Scope128H lidar.

[0034] LiDAR point cloud data, which calculates the distance to an object by measuring the time interval between the transmitted and received pulse signals, is essentially a "cloud of points." LiDAR actively emits laser beams and calculates the distance to the target point by measuring the time it takes for the light to hit an object or surface and reflect back. This rapid repetition of the process acquires millions of data points, allowing the instrument to construct a complex "map" of the spatial surface it is measuring, known as a "point cloud." After preprocessing such as joint calculation and bias correction, clustering, and organization extraction, a digital three-dimensional space easily distinguishable by human vision can be constructed, similar to the effect of "building a tower from grains of sand."

[0035] The LiDAR 4 can scan transport vehicles in real time, collecting 3D shape, size, and other feature data. Using this collected data, the LiDAR 4's processing unit can construct a 3D model of the vehicle. A preset algorithm then processes and analyzes this model to extract key vehicle features, such as length, width, height, and specific shape characteristics. The preset algorithm can reference mature algorithms in existing technologies. In application, the height and angle of the radar detection system's support components can be adjusted to ensure accurate measurement of vehicle dimensions.

[0036] The LiDAR 4 is mounted on a movable first support component, allowing for rapid deployment to designated locations within the detection area, significantly improving detection efficiency and flexibility. Employing advanced sensor technology and data processing algorithms, the LiDAR 4 accurately measures vehicle weight and dimensions. The mobile transport vehicle detection system automatically completes data acquisition, processing, and analysis, reducing human intervention and errors.

[0037] In this embodiment of the specification, the mobile transport vehicle detection system includes a weighing platform and a radar detection system. Multiple weighing platforms are detachably mounted on the ground in the detection area and arranged sequentially at preset distances along a preset direction to collect the weight information of the transport vehicle. The radar detection system includes a movable support frame and a lidar 4 component located at the top of the support frame, used to collect the dimensional information of the transport vehicle. By employing a movable weighing platform and a radar detection system to automatically collect the weight and dimensional information of the transport vehicle, the detection efficiency and flexibility of the transport vehicle are improved.

[0038] Furthermore, in the embodiments of this specification, the first support assembly includes a support portion, a vertical fixing rod 1, and a horizontal fixing rod 2; wherein, the support portion includes three identical support legs 3, the support legs 3 are inclined, the top ends of the three support legs 3 are fixed to the vertical fixing rod 1, and the bottom ends of the three support legs 3 are located at the three vertices of an equilateral triangle; the horizontal fixing rod 2 is located at the top of the vertical fixing rod 1, the horizontal fixing rod 2 intersects the vertical fixing rod 1 perpendicularly, and is fixedly connected.

[0039] Figure 1 This is a schematic diagram of the radar detection system provided in the embodiments of this specification.

[0040] like Figure 1 As shown, the first support assembly may include a support section, a vertical fixing rod 1, and a horizontal fixing rod 2. The support section includes three identical support legs 3, which are inclined and whose bottom ends are located at the three vertices of an equilateral triangle. This provides a stable triangular support structure, enhancing the overall stability of the assembly. The support legs 3 are foldable for easy storage.

[0041] The vertical fixing rod 1 serves as the connection point at the top of the support leg 3, providing vertical support and connecting and supporting the upper horizontal fixing rod 2 and the lower support leg 3. The horizontal fixing rod 2 is located at the top of the vertical fixing rod 1, intersecting it perpendicularly, and the two are fixedly connected.

[0042] In application, the first support component can be deployed in a suitable location in the detection area as needed, greatly improving detection efficiency and flexibility.

[0043] To facilitate users in viewing the detection information of transport vehicles, the radar detection system described in this embodiment may further include an image acquisition device 5, which is located on the horizontal fixed rod 2.

[0044] In the embodiments of this specification, the image acquisition device 5 can be a camera. The image acquisition device 5 captures image information of the vehicle and can output it to a display screen or storage device for inspection personnel to view and manage.

[0045] To facilitate the identification of license plate information of transport vehicles, the mobile transport vehicle detection system in the embodiments of this specification may further include:

[0046] A license plate recognition component, disposed within the detection area, includes a movable second support component and a license plate recognition device located at the top of the second support component. When the license plate recognition device receives a second detection signal indicating that the transport vehicle has entered the detection area, it collects the license plate information of the transport vehicle. The recognized license plate information can provide a basis for subsequent vehicle tracking, management, and data analysis. Simultaneously, the control center can quickly retrieve the vehicle's historical records based on the license plate information, providing a reference for subsequent weight and size detection, thereby improving detection efficiency and accuracy.

[0047] In the embodiments described in this specification, the second support component can be the same as the first support component. When the license plate recognition device receives a second detection signal indicating that a transport vehicle has entered the detection area, it can collect and identify the license plate information of the transport vehicle. The license plate recognition device can transmit the vehicle's license plate information to the control center wirelessly, adjusting the height and angle of the support component of the license plate recognition component to ensure accurate identification of the license plate information. Both the radar detection system and the license plate recognition component can adopt a movable structure, facilitating rapid deployment and relocation, thus improving the system's flexibility and portability.

[0048] By employing LiDAR and license plate recognition technology, rapid and accurate detection of oversized transport vehicles is achieved.

[0049] To improve the flexibility of the lidar 4, the radar detection system described in this embodiment further includes a battery assembly 7 and a wireless data transmission assembly 6; wherein the battery assembly 7 is located inside the vertical fixing rod 1 and is electrically connected to the lidar 4; the wireless data transmission assembly 6 is located inside the horizontal fixing rod 2 and is electrically connected to the lidar 4.

[0050] In the embodiments described in this specification, the battery assembly 7 is built into the vertical fixing rod 1 and electrically connected to the lidar 4 to provide a stable power supply. The battery assembly should have characteristics such as high energy density, long life and fast charging.

[0051] The wireless data transmission component 6 is built into the horizontal fixed rod 2 and is electrically connected to the lidar 4 to transmit the collected data to the control center in real time. The wireless data transmission component 6 preferably uses Wi-Fi wireless communication technology to ensure the real-time nature and accuracy of the data.

[0052] The built-in battery component 7 and wireless data transmission component 6 ensure that the system can still operate normally without external power and network, improving the system's practicality and applicability.

[0053] To facilitate the movement of the support assembly, in this embodiment of the specification, the first support assembly further includes a plurality of wheels, which are located at the lower part of the vertical fixing rod 1.

[0054] In the embodiments described in this specification, several wheels are located at the lower part of the vertical fixing rod 1, which facilitates the movement and deployment of the entire radar detection system.

[0055] Furthermore, in the embodiments of this specification, the mobile transport vehicle detection system may also include a control center and a display device; the weighing platform and the radar detection system are communicatively connected to the control center, and the display device is electrically connected to the control center.

[0056] In the embodiments described in this specification, the control center is responsible for receiving, processing, and analyzing data from the weighing platform, radar detection system, and license plate recognition component, and generating detection results. The detection results may include vehicle license plate information, vehicle weight information, and vehicle size information, etc.

[0057] The display device is electrically connected to the control center and is used to display the test results in real time, including vehicle weight, dimensions, and license plate information, so that managers can view and operate them. Users can also use the display device to set parameters and perform other operations.

[0058] The connection between the control center and the display device enables real-time feedback of test results, facilitating timely action by management personnel.

[0059] To facilitate adjustment of the height of the lidar 4, the vertical fixing rod 1 described in this embodiment further includes multiple vertical sub-rods from top to bottom, with the upper vertical sub-rod nested within the adjacent lower vertical sub-rod, and the upper vertical sub-rod extending or retracting along the axis of the vertical fixing rod 1.

[0060] In this embodiment, the vertical fixing rod 1 comprises multiple vertical sub-rods from top to bottom. Each vertical sub-rod is designed to be nested, meaning that the upper vertical sub-rod can be nested within the adjacent lower vertical sub-rod along the axis of the vertical fixing rod 1, thereby achieving overall height adjustment of the vertical fixing rod 1. The upper vertical sub-rod can be extended or retracted along the axis manually or electrically to adapt to changes in road surface and vehicle height. The height of the first support assembly is limited to 6 meters, and the retracted height does not exceed 1.5 meters.

[0061] Furthermore, in the embodiments of this specification, the first support component may also include a lifting device 8 located on the vertical fixed rod 1, the lifting device 8 being used to drive the relative movement between the vertical sub-rods to realize the extension and retraction of the vertical fixed rod 1.

[0062] In the embodiments described in this specification, the lifting device 8 is located on the vertical fixed rod 1 and is used to drive the relative movement between the vertical sub-rods to realize the extension and retraction of the vertical fixed rod 1. The lifting device 8 can be electric, hydraulic, or pneumatic, and its height can be intelligently adjusted through a controller or manual operation.

[0063] Furthermore, the support portion described in the embodiments of this specification may also include three support rods, one end of which is rotatably fixed to the vertical fixed rod 1, and the other end of which is rotatably fixed to the support leg 3.

[0064] In the embodiments described in this specification, one end of each support rod is rotatably fixed to the vertical fixed rod 1, and the other end of the support rod is rotatably fixed to the support leg 3, so that the entire support part can form a stable tripod structure, better adapt to uneven or tilted ground, and provide solid support for the equipment mounted on it.

[0065] Figure 2 This is a schematic diagram illustrating an application scenario of a mobile transport vehicle inspection system provided in the embodiments of this specification.

[0066] like Figure 2 As shown, a flat, gravel-free solid surface is selected, and the weighing platform is placed at the preset position and distance, ensuring communication connection with the control center. As needed, the height of the vertical fixing rod 1 of the first support component in the radar detection system is adjusted using the lifting device 8, while simultaneously establishing a communication connection with the control center. The height of the license plate recognition component is adjusted, and communication connection with the control center is established. The control center receives data from each component and connects to the display device.

[0067] When a transport vehicle enters the detection area and its wheels slowly and uniformly travel onto all the weighing platforms, the platforms begin collecting the vehicle's weight information and sending it to the control center. Upon receiving the detection signal that the transport vehicle has entered the detection area, the license plate recognition unit begins collecting the vehicle's license plate information and sends it to the control center. Upon receiving the detection signal that the transport vehicle has entered the detection area, the LiDAR 4 begins collecting the vehicle's dimensions and sends it to the control center via the wireless data transmission component 6. The control center receives and processes the information collected by the weighing platforms, license plate recognition unit, and LiDAR, performing preprocessing, feature extraction, classification, and recognition, ultimately generating the detection results. The detection results are sent to a display device, which displays the vehicle's weight, dimensions, and license plate information in real time. Management personnel view the detection results on the display device and perform corresponding operations or record them.

[0068] Specifically, when the transport vehicle is 2-3 meters away from the weighing platform, the user clicks the "Start" button on the display device's testing interface. At this time, the ready indicator light on the interface changes from green to yellow, indicating that the system is performing data initialization work for each device before testing.

[0069] After the data initialization is complete, the ready indicator light on the interface will turn green. The vehicle under inspection can slowly and uniformly pass through the weighing platform. At this time, the LiDAR 4 collects the three-dimensional shape, size and other feature data of the transport vehicle. When the last axle of the vehicle under inspection has completely left the weighing platform, click the "Stop" button to end the inspection. The weight and external dimensions of the vehicle are then detected.
