[0023] In order to make the purpose, 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 combination with the specific embodiments of this specification and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of this specification, not all of the embodiments. Based on the embodiments in this specification, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of one or more embodiments of this specification.

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

[0025] In order to solve the defects in the prior art, this solution provides the following embodiments:

[0026] A mobile transport vehicle detection system provided in the embodiments of the specification is specifically described in conjunction with the accompanying drawings.

[0027] The mobile transport vehicle detection system in the embodiments of this specification may include:

[0028] There are multiple weighing platforms, which are detachably arranged on the ground of the detection area and arranged in sequence along a preset direction and at a preset distance; when the wheels of the transport vehicle are located on all the weighing platforms, the weight information of the transport vehicle is collected;

[0029] The radar detection system is arranged in the detection area, and includes a movable first support component and a laser radar 4 located at the top of the first support component; when the laser radar 4 receives a first detection signal when the transport vehicle enters the detection area, the laser radar 4 collects the size information of the transport vehicle.

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

[0031] The weighing platform is used to measure the weight of transport vehicles. By arranging multiple weighing platforms in a preset direction and distance on the ground of the detection area, it can be ensured that the wheels of the transport vehicles can press on all the weighing platforms when passing by, so as to collect the weight information of the vehicles. The detachable design of the weighing platform is convenient for moving or repairing it when necessary. In order to facilitate the transport vehicles to better roll over the weighing platform, the preset direction of the weighing platform is arranged perpendicular to the direction of the transport vehicles entering the detection area, and the center distance between the weighing platforms is adjusted to make it consistent with the center distance of the average wheelbase on each set of axles of the transport vehicles.

[0032] In practical applications, a flat solid road surface without sand and gravel particles is selected, and a wireless weighing platform is placed. The distance and position between each weighing platform are adjusted to ensure the accuracy of the detection. The weighing platform can be a wireless weighing platform, and the number can be 4. The 4 weighing platforms are divided into a group of two, and the wheels on one side of the vehicle roll over one of the groups. In order to ensure that the vehicle weight can be accurately measured, the wheels on both sides of the front axle of the vehicle roll over the 4 weighing platforms at the same time. After the front axle passes, the wheels on both sides of the rear axle also roll over the 4 weighing platforms at the same time, thereby completing the collection of the weight information of the transport vehicle. The size of each weighing platform is preferably 800mm×450mm×30mm.

[0033] The first support assembly is used to support the laser radar 4. The laser radar 4 is located at the top of the first support assembly and is used to detect and collect data. When the laser radar 4 receives the first detection signal that the transport vehicle enters the detection area, the laser in the laser radar 4 emits a light pulse to the outside. The laser is irradiated to the target object and diffuse reflection is generated. The photoelectric sensor in the laser radar 4 receives the diffuse reflection light. The laser radar 4 measures the flight time of the laser pulse from emission to reception and calculates the distance from the target object to the laser radar 4. For example: the target object is a transport vehicle, the laser radar 4 is a Scope128H laser radar, and the size information of the transport vehicle is calculated based on the Scope128H laser radar.

[0034] The distance of an object is calculated by measuring the time interval between the sent and received pulse signals. LiDAR point cloud data is a "cloud composed of points". LiDAR actively emits a laser beam and measures the time required for the light to hit an object or surface and then reflect back to calculate the distance from the target point to the laser radar. Millions of data points will be obtained during the rapid repetition of this behavior. The instrument will build a complex "map" of the spatial surface it is measuring, called a "point cloud". After preprocessing, clustering, and extraction of joint solutions, deviation correction, etc., a digital three-dimensional space that is easy for human vision to distinguish can be constructed, similar to the effect of "building a tower out of sand".

[0035] The laser radar 4 can scan the transport vehicle in real time and collect the characteristic data of the three-dimensional shape, size and other characteristics of the transport vehicle. Using the collected characteristic data, the processing device of the laser radar 4 can construct a three-dimensional model of the vehicle, and process and analyze the collected three-dimensional model through a preset algorithm to extract the characteristic information of the vehicle, such as length, width, height and specific shape characteristics. The preset algorithm can refer to the mature algorithm in the prior art. In the application, the height and angle of the support component of the radar detection system can be adjusted to ensure that the size information of the vehicle can be accurately measured.

[0036] The laser radar 4 is mounted on the movable first support assembly and can be quickly deployed to the designated location of the detection area, greatly improving the detection efficiency and flexibility. The laser radar 4 uses advanced sensor technology and data processing algorithms to accurately measure the vehicle weight and the length, width and height of the vehicle. The mobile transport vehicle detection system can automatically complete data collection, processing and analysis, reducing human intervention and errors.

[0037] In the embodiments of the present specification, the mobile transport vehicle detection system includes a weighing platform and a radar detection system, wherein a plurality of weighing platforms are detachably disposed on the ground of the detection area and are arranged in sequence along a preset direction at a preset distance, for collecting weight information of the transport vehicle; the radar detection system includes a movable support frame and a laser radar 4 component located at the top of the support frame, for collecting size information of the transport vehicle. By using a movable weighing platform and a radar detection system to automatically collect weight information and size information of the transport vehicle, the detection efficiency and flexibility of the transport vehicle are improved.

[0038] Furthermore, in the embodiment of the present specification, the first supporting assembly includes a supporting part, a vertical fixing rod 1 and a horizontal fixing rod 2; wherein, the supporting part includes three completely identical supporting legs 3, the supporting legs 3 are arranged at an angle, the top ends of the three supporting legs 3 are fixed on the vertical fixing rod 1, and the bottom ends of the three supporting legs 3 are located at the three vertices of an equilateral triangle; the horizontal fixing rod 2 is located at the top end of the vertical fixing rod 1, and the horizontal fixing rod 2 intersects with the vertical fixing rod 1 vertically and is fixedly connected.

[0039] Figure 1 A schematic diagram of the structure of a radar detection system provided in an embodiment of this specification.

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

[0041] The vertical fixing rod 1 is the connection point at the top of the supporting leg 3, and plays a role of vertical support, which can connect and support the horizontal fixing rod 2 above and the supporting leg 3 below. The horizontal fixing rod 2 is located at the top of the vertical fixing rod 1, intersecting the vertical fixing rod 1 vertically, and the two are fixedly connected.

[0042] In applications, the first supporting assembly can be deployed at a suitable position in the detection area as needed, which greatly improves the detection efficiency and flexibility.

[0043] In order to facilitate users to view the detection information of the transport vehicle, further, the radar detection system in the embodiment of this specification may also include an image acquisition device 5, and the image acquisition device 5 is located on the horizontal fixing rod 2.

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

[0045] In order to facilitate the identification of the license plate information of the transport vehicle, further, the mobile transport vehicle detection system in the embodiment of this specification may also include:

[0046] The license plate recognition component is arranged in the detection area, and 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 the second detection signal that the transport vehicle enters the detection area, the license plate recognition device 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. At the same time, the control center can quickly retrieve the historical record of the vehicle based on the license plate information, and provide a reference for subsequent weight and size detection, thereby improving the detection efficiency and accuracy.

[0047] In the embodiments of this specification, the second support assembly can be the same as the first support assembly. When the license plate recognition device receives the second detection signal of the transport vehicle entering 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 by wireless transmission, and adjust the support assembly height and angle of the license plate recognition assembly to ensure that the license plate information can be accurately identified. Both the radar detection system and the license plate recognition assembly can adopt a movable structure, which is convenient for rapid deployment and movement, and improves the flexibility and portability of the system.

[0048] The use of LiDAR 4 and license plate recognition technology enables fast and accurate detection of large transport vehicles.

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

[0051] The wireless data transmission component 6 is built into the horizontal fixed rod 2 and electrically connected to the laser radar 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 and accuracy of the data.

[0052] The built-in battery assembly 7 and wireless data transmission assembly 6 ensure that the system can still work normally without an external power supply and network, thereby improving the practicality and application scope of the system.

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

[0054] In the embodiment of this specification, a plurality of wheels are located at the lower part of the vertical fixing rod 1 to facilitate the movement and deployment of the entire radar detection system.

[0055] Furthermore, the mobile transport vehicle detection system in the embodiment of the present specification 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 of this specification, the control center is responsible for receiving, processing and analyzing data from the scale, radar detection system and license plate recognition component, and generating detection results, which may include vehicle license plate information, vehicle weight information, 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, size and license plate information, etc., to facilitate management personnel to view and operate. Users can perform parameter settings and other operations through the display device.

[0058] Through the connection between the control center and the display device, real-time feedback of the test results is achieved, which is convenient for management personnel to make corresponding operations in time.

[0059] In order to facilitate the adjustment of the height of the laser radar 4, further, the vertical fixed rod 1 described in the embodiment of this specification includes multiple vertical sub-rods from top to bottom, the upper vertical sub-rods are nested in the adjacent lower vertical sub-rods, and the upper vertical sub-rods can be extended or retracted along the axis of the vertical fixed rod 1.

[0060] In the embodiment of this specification, the vertical fixing rod 1 includes multiple vertical sub-rods from top to bottom, and each vertical sub-rod is designed to be nested, that is, the vertical sub-rod located at the top can be nested in the adjacent vertical sub-rod below along the axis of the vertical fixing rod 1, so as to achieve the 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 the changes in different road surfaces and vehicle heights. The height of the first support assembly is limited to 6 meters, and the height after storage does not exceed 1.5 meters.

[0061] Furthermore, in the embodiment of the present specification, the first supporting assembly may also include a lifting device 8 located on the vertical fixing rod 1, and the lifting device 8 is used to drive the relative movement between the vertical sub-rods to achieve the extension and retraction of the vertical fixing rod 1.

[0062] In the embodiment of 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 achieve the extension and retraction of the vertical fixed rod 1. The lifting device 8 can be electric, hydraulic or pneumatic, and can achieve intelligent height adjustment through a controller or manual operation.

[0063] Furthermore, the support portion in the embodiment of the present specification may also include three support rods, one end of each support rod may be rotatably fixed to the vertical fixing rod 1 , and the other end of each support rod may be rotatably fixed to the supporting leg 3 .

[0064] In the embodiments of the present 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, which can better adapt to the unevenness or inclination of the ground and provide solid support for the equipment mounted on the upper end.

[0065] Figure 2 A schematic diagram of an application scenario of a mobile transport vehicle detection system provided in an embodiment of this specification.

[0066] like Figure 2 As shown, a flat solid road surface without sand and gravel particles is selected, the weighing platform is placed according to the preset position and distance, and the communication connection with the control center is ensured. According to actual needs, the height of the vertical fixing rod 1 of the first supporting component in the radar detection system is adjusted by the lifting device 8, and a communication connection is established with the control center. The height of the license plate recognition component is adjusted and the communication connection with the control center is established. The control center receives data from each component and connects with the display device.

[0067] When the transport vehicle enters the detection area and the wheels of the transport vehicle slowly and evenly drive to all the weighing platforms, the weighing platforms begin to collect the weight information of the transport vehicle and send it to the control center. When the license plate recognition device of the license plate recognition component receives the detection signal that the transport vehicle enters the detection area, it begins to collect the license plate information of the transport vehicle and sends it to the control center. When the laser radar 4 receives the detection signal that the transport vehicle enters the detection area, it begins to collect the size information of the transport vehicle and sends it to the control center through the wireless data transmission component 6. The control center receives and processes the information collected by the weighing platform, license plate recognition device, and laser radar, performs preprocessing, feature extraction, classification and recognition, etc., and finally generates the detection results. The detection results are sent to the display device, which displays the vehicle weight, size, license plate, etc. in real time. The management personnel view the detection results through the display device and perform corresponding operations or records.

[0068] Specifically, when the transport vehicle travels to a position 2 to 3 meters away from the scale platform, the user clicks the "Start" button in the detection interface of the display device. At this time, the ready indicator light in the interface changes from green to yellow, indicating that the system is initializing the data of each device before the detection.

[0069] After the data initialization is completed, the ready indicator light in the interface turns green, and the inspected vehicle can pass through the scale slowly and evenly. At this time, the lidar 4 collects the three-dimensional shape, size and other characteristic data of the transport vehicle. When the last axle of the inspected vehicle completely drives out of the scale, click the "Stop" button to end the detection, and the vehicle's weight and external dimension data detection is completed.

The various embodiments in this specification are described in a progressive manner, and the same and similar parts between the various embodiments can be referenced to each other, and each embodiment focuses on the differences from other embodiments.
