Vehicle load determination system and method

Abstract

A vehicle load determination system and method are proposed, belonging to the technical field of driving load detection, the system includes: a high-speed camera device, a support and fixation device, a wireless data acquisition and transmission device, a picture analysis and data processing system; the support and fixation The device is used to fix a high-speed camera device and a wireless data collection and transmission device; the high-speed camera device is used to photograph the tires of passing vehicles; the wireless data collection and transmission device is used to collect tire images taken by the high-speed camera device, And send the tire image to the image analysis and data processing system; the image analysis and data processing system is used to identify the tire image, obtain the basic information of the tire in the tire image, determine the load of the tire, and determine the vehicle load. The method and system can measure the load size of various vehicles more accurately and flexibly.

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...

[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

[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.
