[0002] If a vehicle is overloaded, it will not only damage the road surface but also pose a safety hazard. The existing methods of managing overloading are mostly to weigh the vehicle at the toll booth, impose a fine if overloading is found, or to stop the vehicle for weighing if a suspected overloaded vehicle is found on the lane.

[0003] Currently, all highway toll gates utilize off-site enforcement systems for overweight control. Off-site enforcement is a method of law enforcement conducted without direct face-to-face contact. It utilizes modern technology, such as video surveillance and remote control, to monitor and penalize violations. Off-site enforcement at highway toll gates utilizes multiple scales equipped with built-in sensors, embedded in the ground where vehicles pass. These weigh passing vehicles and report the weight to the overall system, which then uses video camera analysis and other methods to determine whether the vehicle is overweight.

[0004] As the demand for traffic management continues to grow, off-site enforcement is no longer limited to highway toll booths but is gradually being applied to various roads. Different road conditions necessitate the design of different overweight vehicle control systems. To determine the adaptability of overweight vehicle control systems, they must be tested and assessed on a test platform before being installed and implemented on-site, thus preventing operational deficiencies after installation.

[0016] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in combination with the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0017] like Figure 1-2As shown, the utility model is based on a simulated overload control test platform device on a highway, including a walkway platform 1, a main side platform 2, an auxiliary side platform 3, a weighing platform model 4, a model trolley 5, a model coil 6, a detection platform 7, a license plate capture camera 8 and a light curtain device 9. The walkway platform 1 is a long rectangular walkway board, and a U-shaped main side platform 2 and an auxiliary side platform 3 are respectively installed in the middle of the two long sides of the walkway platform 1. The U-shaped openings of the main side platform 2 and the auxiliary side platform 3 are arranged relative to each other, and a rectangular groove is provided on the walkway platform 1 in the rectangular groove formed by the two U-shaped openings. The weighing platform model 4 is fixedly installed in the rectangular groove. The top surface of the weighing platform model 4 and the top surface of the walkway platform 1 are located in the same plane. The model trolley 5 is a four-wheeled trolley and a weight bucket is installed on the upper part of the trolley. At one end of the top surface of the walkway platform 1, the direction of the model car 5 is defined as the front end of the walkway platform 1. A hidden groove is provided at the bottom of the front side wall of the rectangular groove, in which a model coil 6 is fixedly installed. A detection platform 7 is installed on the top surface of the main side platform 2, and a display screen is provided on the top of the detection platform 7. A license plate capture camera 8 is installed on both sides of the main side platform 2 corresponding to the front and rear of the model car 5. A pair of light curtain devices 9 are provided at the front of the weighing platform model 4. The pair of light curtain devices includes two light curtain devices installed on the main side platform 2 and the auxiliary side platform 3 respectively. Model license plates are attached to the front and rear sides of the weight bucket of the model car 5. The weighing platform model 4, model coil 6, detection platform 7, license plate capture camera 8 and light curtain device 9 are all electrically connected to the detection platform 7. The weighing platform model 4 and model coil 6 are scaled-down models of the same function of the designed overweight control system. The license plate capture camera 8 and light curtain device 9 are scaled-down models of the same function of the designed overweight control system. The model car 5 in the present invention is remotely controlled, and the control key can be set on the detection platform 7, or a separate remote controller can be set for operation.

[0018] When in use, all operations are carried out on the test bench 7, and the display screen can show the operation steps and test results. A certain amount of weight is added to the weight bucket of the model car 5, and then it is controlled to move straight through the model coil 6 and the scale model 4 on the walkway platform 1. The model coil detects the vehicle and feeds back to the test bench 7. The test bench 7 commands the detection system to start. When the model car 5 moves onto the scale model 4, the light curtain device 9 detects the car and triggers the internal sensor of the scale model 4 to detect the weighing. The weighing result is transmitted to the test bench 7, which performs calculation and analysis and displays the result on the display screen. The operator determines whether the test result is accurate based on the test result and the weight in the weight bucket of the model car 5. During the weighing process, the license plate capture camera 8 takes pictures of the model license plate on the front and back sides of the weight bucket and transmits them to the test bench 7 for analysis to determine whether the test is accurate and applicable.

[0019] The walkway platform 1 is installed on the base long plate 10, and the walkway platform 1 is composed of two lane dividing plates divided by the longitudinal axis. The four corners of the walkway platform 1 are fixed to the base long plate 10 by bolts 11. The bolts 11 used for fixing each corner are not limited to one, and multiple bolts 11 can be used for fixing. The base long plate 10 is provided with multiple adjustment screw holes 12 for fixing the bolts 11. The corresponding adjustment screw holes 12 are selected for fixing according to the adjustment position of the walkway platform 1, so that the distance between the two lane dividing plates can be adjusted to achieve the overload control system detection of roads designed with different widths.

[0020] The ground below the four corners of the base long plate 10 is provided with a cylinder deep hole 13, and a tilt cylinder 14 is installed in each cylinder deep hole 13. The cylinder body of the tilt cylinder 14 is fixed in the cylinder deep hole 13, and the piston rod of the tilt cylinder 14 is vertically upward and hinged with a slider 15 at the end. The bottom surface of the four corners of the base long plate 1 is provided with an inverted convex shaped slide groove, and the slider 15 is slidably installed in the large groove of the corresponding convex shaped slide groove above. The extension and contraction of the tilt cylinder 14 can effectively control the lifting and lowering of the base long plate 10, and the sliding of the slider 15 in the slide groove can effectively adjust and compensate for the distance difference caused by the extension and contraction of the piston rod of the tilt cylinder 14. The lifting height difference at both ends of the base long plate 10 makes it form the same slope as the actual lane, so as to better simulate the actual lane usage effect of the overload control system.

[0021] like Figure 3 As shown, a control box 52 is fixedly installed on the bottom surface of the weight bucket 51 of the model car 5, and a seat 53 is fixedly connected to the bottom surface of the control box 52. An axle is respectively installed in front and behind the seat 53, and wheels 54 are installed at both ends of the axle. The seat 3 is fixed to the weight bucket 1, which plays a role in connecting, fixing and bearing pressure on the control box, the axle and the weight bucket. A power system for driving the wheels 54 to rotate is provided in the control box 52. The power system is connected to the axle through a transmission mechanism and drives the wheels 54 to rotate and move through the axle. This structure is a prior art and is not described in detail in this application. The power system is controlled by a wireless remote control to control various actions of the model car.

[0022] A lifting cylinder 55 is installed on the bottom of the control box 52 of the model car 5, and the cylinder body of the lifting cylinder is fixed to the bottom of the control box (it can also be fixed to the bottom of the seat 53), and the piston rod of the lifting cylinder 55 is vertically downward and a pressure dividing plate 56 is fixed at the end. The wheel 54 is installed at the end of the axle through a telescopic sleeve, and the cylinder that controls the extension and retraction of the telescopic sleeve is installed inside the axle and the power device that controls the extension and retraction of the cylinder is installed in the control box 52. The piston rod of the lifting cylinder 55 is extended to support the pressure dividing plate 56 on the base long plate 10 or the walkway platform 1, lifting the model car 5 and separating the wheels from the walkway platform (there is no need to lift it too high, the wheels can just move away from the surface of the walkway platform), and then the telescopic sleeve is controlled to extend and retract according to actual needs to adjust the wheel spacing of the model car 5, so that it is suitable for simulation of different models.

[0023] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents.
