Description

Technical Field

[0001] This utility model relates to the field of wheel and axle recognition technology, specifically to a vehicle wheel and axle recognition and detection device. Background Technology

[0002] With the development of science and technology, my country's highway construction and road transportation have ushered in an unprecedented peak of development. Therefore, it is necessary to use monitoring equipment to accurately acquire as much vehicle characteristic data as possible to provide data support for weight-based toll collection and enforcement of overloaded vehicles on highways and bridges (toll stations). Among these, the wheel and axle type of the vehicle is an essential characteristic data.

[0003] Currently, toll stations install piezoelectric wheel axle recognition devices at the bottom of the vehicle entry lane. However, during use, due to the large number of vehicles detected daily, these devices are constantly subjected to vehicle pressure. Over time, this leads to significant lifespan damage to pressure-bearing wheel axle sensors, increasing the frequency of repairs. To reduce repair frequency and improve detection intelligence, wheel axle image recognition devices have been introduced to the market. These devices use cameras to capture real-time wheel axle images and combine them with intelligent algorithms to accurately identify the number of wheel axles, wheelbase, tire type (single / dual tire), and vehicle type, thereby measuring the wheel axle information of vehicles passing through the lane.

[0004] However, existing visual axle detectors are fixed installations, usually mounted on the side of the toll station entrance lane. To make the visual axle detection clearer, they are mounted at a higher position on the road pole. However, when they need to be inspected regularly, the high mounting position makes maintenance inconvenient. To solve the above problems, a vehicle axle recognition and detection device is proposed. Utility Model Content

[0005] In view of this, the present invention provides a vehicle wheel axle recognition and detection device. The present invention drives the lifting block to rise and fall by activating the electric lifting rod, thereby causing the connecting block and the irregularly shaped slider connected to the lifting block to move up and down, thereby causing the wheel axle image recognition device installed on the irregularly shaped slider to rise and fall, thus facilitating the maintenance of the wheel axle image recognition device.

[0006] To solve the above-mentioned technical problems, this utility model provides a vehicle wheel axle identification and detection device, including a weighbridge installed in the vehicle entrance channel, anti-collision blocks installed on the left and right sides of the vehicle entrance channel, triangular plates installed at the front and rear ends of the weighbridge, road poles installed on the left and right sides of the vehicle entrance end of the vehicle entrance channel, wheel axle image recognition devices installed on the road poles, a cavity is provided in the road pole along its axial direction, an electric lifting rod is provided at the bottom of the cavity, a lifting block is provided at the top of the electric lifting rod, and a wheel axle image recognition device is provided on the side of the lifting block near the vehicle entrance channel. Each anti-collision block is provided with a detection chamber, and multiple axle sensors are embedded in each detection chamber.

[0007] Each lifting block has a connecting block on the side closest to the crash barrier. The connecting block is used to connect the irregularly shaped slider to the lifting block. Each connecting block has an irregularly shaped slider on the side closest to the crash barrier. The irregularly shaped slider is used to connect the connecting block to the rotating base. The rotating base is tilted downwards and is used to control the rotation angle of the camera on the wheel axle image recognition device. The wheel axle image recognition device is rotated on the bearing surface of the rotating base and is used to identify the number of vehicle wheel axles.

[0008] The testing compartments are hollow inside and are arranged along the axis of the crash barriers. Each testing compartment has a crash beam on the side closest to the vehicle entry channel. The crash beam is designed to prevent the axle sensors from colliding with the vehicle and is U-shaped.

[0009] A fixed pole is installed in the center of the top of the inspection compartment. The fixed pole is used to fix and install reflective warning strips. The fixed pole is set along the axis of the crash barrier. A reflective warning strip is installed on the side of the fixed pole closest to the vehicle entrance. The reflective warning strip is used to remind the driver that there are crash barriers on both sides of the vehicle entrance, thereby improving the driver's awareness of safe driving.

[0010] Multiple support rods are installed on the side of the fixed rod away from the vehicle entry channel. The support rods are used to fix and install the wheel axle supplement lights. Each support rod is rotatably equipped with a wheel axle supplement light. The wheel axle supplement light illuminates the area near the wheel axle of the vehicle passing through the vehicle entry channel, so that the wheel axle image recognition device can record the vehicle wheel axle information more clearly. The light surface of the wheel axle supplement light faces the vehicle entry channel.

[0011] A support block is installed at one corner of the vehicle entrance lane. The support block is used to install a sensor-activated supplementary light. The sensor-activated supplementary light is used to detect the license plate of the vehicle to enter the vehicle entrance lane and provide supplementary light. A pole is installed on the upper part of the housing of the sensor-activated supplementary light. The pole is used to fix and install the license plate recognition device. The license plate recognition device is installed on the upper part of the pole and is used to capture and collect information of the vehicle to enter the vehicle entrance lane.

[0012] A support block is installed at one corner of the vehicle entry and exit end of the vehicle access channel. The support block is used to fix and install the positioning rod. The positioning rod is installed on the upper part of the support block. The positioning rod is used to fix and install the weighing information display screen. The weighing information display screen is used to display the load information of vehicles passing through the weighbridge for the driver's convenience.

[0013] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0014] 1. By starting the electric lifting rod, the lifting block is raised and lowered, which in turn causes the connecting block and the irregularly shaped slider connected to the lifting block to move up and down, thereby raising and lowering the wheel axle image recognition device installed on the irregularly shaped slider, thus facilitating the maintenance of the wheel axle image recognition device.

[0015] 2. The anti-collision beam is used to prevent the axle sensor from colliding with the vehicle. The fixing rod is used to fix and install the reflective warning strip. The reflective warning strip is used to remind the driver that there are anti-collision barriers on both sides of the vehicle access road. The anti-collision barriers are made of concrete, thereby improving the driver's awareness of safe driving.

[0016] 3. By using a sensor-activated supplemental lighting system in conjunction with a license plate recognition device, the license plates of vehicles entering the vehicle lane are illuminated. The license plate recognition device identifies the vehicle's registered information at the vehicle management office, thereby measuring the vehicle's load information. Real-time load information is then obtained by combining axle sensors and a weighbridge. The original load information is measured by the license plate recognition device, and the axle information is recorded in real time by a wheel axle image recognition device. The number of axles and the span of the axles are then measured again by the axle sensors. Finally, the load value is obtained by comparing the measurements with the wheel axle image recognition device. This detection method improves the accuracy of measuring vehicle axles and their load.
