Problems solved by technology

[0002] With the improvement of our country's economic level, more roads and bridges are put into use, and the connection between various places is getting closer. It is precisely because of this that more and more vehicles of different grades are driving on roads and bridges. , as small as electric vehicles, family cars, as large as dump trucks, semi-trailers, etc., once these vehicles are overloaded, roads and bridges will be damaged, and the damage of road bridges will not only endanger people's personal safety, but also It will also cause a certain loss to public property, so preventing overweight and overloading is an important part of maintaining traffic safety, and the most common inspection method at present is to send people to check or set up weighbridges at toll stations to check vehicle loads , but this kind of method affects the smoothness of traffic to a certain extent, and it is not comprehensive. Overloaded vehicles can avoid being checked for overloading in other ways, such as driving late at night.
[0003] There are still many existing methods for detecting dynamic vertical loads of vehicles, such as the invention patent publication number: CN106626994A, which is named as a method for detecting tire dynamic vertical loads during vehicle running and the method described in the system, but this type of method uses sensors Fixed on the tire, so the sensor will be affected by tire rotation speed, vibration, frictional heat and other issues, it is difficult to perform accurate calculations
There are also many existing tire load detection methods, such as the invention patent publication number: CN1860042A, which is called the method and system for detecting tire load during vehicle running, but this patent also arranges the sensor on the tire, so it will inevitably The ground is affected by problems such as tire rotation speed, vibration, frictional heat, etc.

Embodiment Construction

[0025] First, if figure 1 As shown, the present invention proposes a vehicle load determination system. The system includes a high-speed camera device, a supporting and fixing device, a wireless data collection and transmission device, a picture analysis and data processing system and a solar power supply system.

[0026] The supporting and fixing device refers to the structure used to fix and adjust the position of the high-speed camera device and the wireless data collection and transmission device beside the bridge or the road, and can be a mechanical support structure to ensure that the high-speed camera device is not affected by Gravity, wind and other factors affect and work stably; the high-speed camera device is used to shoot the tires passing by the vehicle; the wireless data collection and transmission device has a built-in Internet of Things card (IoT) to control communication, which can balance and balance the high-speed camera device Clearing, controlling the swi...

Abstract

The invention provides a vehicle load determining system and method, which belong to the technical field of vehicle load detection. The system comprises a high-speed camera device, a supporting and fixing device, a wireless data acquisition and transmission device and an image analysis and data processing system, wherein the supporting and fixing device is used for fixing the high-speed camera device and the wireless data acquisition and transmission device; the high-speed camera device is used for photographing a tire of a passing vehicle; the wireless data acquisition and transmission deviceis used for acquiring the tire image photographed by the high-speed camera device and sending the tire image to the image analysis and data processing system; and the image analysis and data processing system is used for recognizing the tire image, acquiring the basic information of the tire in the tire image, determining the load of the tire and determining the load of the vehicle. The method and the system provided in the invention can more accurately and flexibly measure the load of each vehicle.

Description

technical field [0001] The invention belongs to the field of road and bridge driving load detection and the technical fields of transportation and intelligent measurement and control, and in particular relates to a vehicle load determination system and method. Background technique [0002] With the improvement of our country's economic level, more roads and bridges are put into use, and the connection between various places is getting closer. It is precisely because of this that more and more vehicles of different grades are driving on roads and bridges. , as small as electric vehicles, family cars, as large as dump trucks, semi-trailers, etc., once these vehicles are overloaded, roads and bridges will be damaged, and the damage of road bridges will not only endanger people's personal safety, but also It will also cause a certain loss to public property, so preventing overweight and overloading is an important part of maintaining traffic safety, and the most common inspectio...
