Description

Technical Field

[0001] This utility model relates to an overload control and inspection robot, belonging to the technical field of vehicle management equipment. Background Technology

[0002] Currently, there is a serious problem of abnormal driving by vehicles using the weighing system at highway entrances. Truck drivers engage in illegal activities such as jumping over scales, rushing onto scales, braking the scale, and manipulating hydraulic axles, resulting in unstable weighing data that deviates significantly from the vehicle's actual readings. This disrupts toll collection order at toll stations and seriously impacts social management and road traffic. To address this practical problem, we propose a vehicle weight-control inspection robot to solve this challenge. Utility Model Content

[0003] The purpose of this utility model is to provide an overload control inspection robot that can intelligently identify vehicles that are driving abnormally, illegally, or in violation of regulations, and will issue an alarm for vehicles that do not comply with dynamic weighing requirements.

[0004] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: a robot for inspecting overloaded vehicles, comprising:

[0005] The identification and detection device is set on one side of the lane. The identification and detection device is equipped with a video image acquisition camera and a lidar scanner. The video image acquisition camera can provide license plate recognition and vehicle photos, and can also provide vehicle video recording. The lidar scanner is used to acquire vehicle start and end information.

[0006] The dynamic weighing controller is connected to both the video image acquisition camera and the lidar scanner.

[0007] A ground dynamic weighing sensor is used to acquire dynamic vehicle weighing data. The ground dynamic weighing sensor is laid on the lane and is electrically connected to a dynamic weighing controller.

[0008] A de-icing device is used to remove ice and snow from the surface of a dynamic weighing sensor. The de-icing device includes drive units disposed on both sides of the dynamic weighing sensor, and an ice blade that can move along the surface of the dynamic weighing sensor is disposed between the two corresponding drive units. When the ice blade moves along the surface of the dynamic weighing sensor, it can scrape away the ice and snow on the surface of the weighing sensor.

[0009] An embedded temperature compensation module is embedded and installed on both sides of the ground dynamic weighing sensor and its surface is in contact with the ground dynamic weighing sensor. The embedded temperature compensation module can maintain the sensor constant temperature and assist in de-icing and snow removal, preventing the sensor sensitivity from decreasing due to low temperature.

[0010] The aforementioned vehicle overload inspection robot has three video image acquisition cameras, which are arranged in a fan shape facing the lane direction to capture information from multiple angles, ensuring that information from the front, rear, and body of the vehicle can be collected, thus guaranteeing the comprehensiveness and accuracy of the information.

[0011] The aforementioned robot for inspecting overloaded vehicles includes an LED information display screen on its identification and detection device. The LED information display screen is connected to a dynamic weighing controller to assist in vehicle guidance, instructing vehicles with designated license plates not to follow too closely and to pass through in an orderly manner, thereby ensuring the system's recognition rate.

[0012] The aforementioned robot for inspecting overloaded vehicles has a supplementary light installed at the lower part of the identification and detection device near the lane direction. The supplementary light is connected to the dynamic weighing controller and can provide supplementary lighting when there is insufficient light to assist in information acquisition.

[0013] The aforementioned overload control inspection robot includes a ground dynamic weighing sensor comprising a first sensor assembly and a second sensor assembly. The first and second sensor assemblies are arranged across the lane and parallel to each other, and are electrically connected to a dynamic weighing controller. Each of the first and second sensor assemblies consists of two weighing sensors arranged along the same straight line. The dynamic weighing controller calculates the axle weight, number of axles, axle type, and vehicle speed of a vehicle by using the weight data obtained from the four weighing sensors and the information acquisition time.

[0014] The aforementioned robot for inspecting overloaded vehicles includes a drive unit comprising strip-shaped grooves on both sides of a dynamic weighing sensor on the ground. A rotatable threaded column is arranged along the length of each groove, and a meshing slider is mounted on the threaded column. One end of a column is located at the top of the slider, and the other end of the column extends upwards to the outside of the groove. An ice blade is positioned between the portions of the two opposing columns extending out of the groove. A drive motor is located at the end of each threaded column and is communicatively connected to a dynamic weighing controller. The drive motor can rotate the threaded column, causing the slider to move along the threaded column. The slider, through the column, drives the ice blade to move along the surface of the dynamic weighing sensor on the ground, removing ice and snow.

[0015] The aforementioned robot for inspecting overloaded vehicles has an ice blade that is tilted vertically and whose lower blade is in contact with the surface of a dynamic weighing sensor on the ground, making it easy to scrape away ice and snow.

[0016] The aforementioned overload control inspection robot includes an embedded temperature compensation module comprising a strip heating module and a temperature sensor. The strip heating module is embedded on both sides of a ground dynamic weighing sensor, and the temperature sensor is located on the side of the ground dynamic weighing sensor. Both the temperature sensor and the strip heating module are communicatively connected to the dynamic weighing controller. The temperature sensor can detect the temperature around the ground dynamic weighing sensor. When the temperature is lower than a set value, the strip heating module is activated to provide heating compensation, ensuring the measurement accuracy of the ground dynamic weighing sensor. Simultaneously, the heating by the strip heating module can also help melt surface ice and snow. The strip heating module can use a heating tape.

[0017] Compared with the prior art, the present invention has at least the following beneficial effects:

[0018] (1) This utility model intelligently identifies abnormal, illegal and unlawful vehicles by using a video image acquisition camera and a laser radar scanner. It will alarm vehicles that do not follow the dynamic weighing requirements, such as speeding over the scale, braking the scale, jumping the scale, using hydraulic jacks, etc. For vehicles passing through the weighing equipment at a constant speed of 10km / h, the weighing data is recognized and accepted by the program, and the ground dynamic weighing sensor obtains complete weighing data.

[0019] (2) When this utility model can identify vehicles that are driving abnormally, illegally or illegally, it can provide evidence of illegal behavior during vehicle weighing through information obtained by video image acquisition camera and lidar scanner, such as vehicle pictures, videos, abnormal weight and other information; and it can also provide sound and light alarms for abnormal vehicles to alert staff to the illegal behavior of the vehicle. At the same time, it can store abnormal data for subsequent processing by relevant departments, solve the problem of on-site monitoring by personnel, and improve the intelligence and digitalization of equipment.

[0020] (3) This utility model is equipped with a de-icing device and an embedded temperature compensation module. The de-icing device can help remove ice, snow and other debris covering the surface of the ground dynamic weighing sensor, and avoid the ground dynamic weighing sensor from being malfunctioning or losing its function due to ice and snow covering. The embedded temperature compensation module can maintain the sensor constant temperature and assist in de-icing and snow removal, and prevent the sensor sensitivity from decreasing due to low temperature, so that this utility model can still operate stably and accurately in the low temperature environment in northern my country.
