Method for measuring weight of dynamic vehicle and system for measuring weight of dynamic vehicle

Abstract

The invention provides a method for measuring the weight of a dynamic vehicle and a dynamic vehicle measuring system. The method comprises the following steps: constructing an equation set which includes a plurality of linear fitting equations which correspond to different vehicle velocities in a one by one manner; acquiring the average velocity of a certain vehicle when the vehicle passing a certain sloped distance and force generated in the horizontal direction and the vertical direction, and calculating a converged force; acquiring from a equation set a linear fitting equation which corresponds to the average velocity of the vehicle and is intended for representing the linear relationship between weight and the joint force, and calculating the weight of the vehicle based on the joint force. The system includes a slope bearing bench, a sensing support, a measuring apparatus, a memory and a processor. According to the invention, the method addresses the measuring inaccuracy caused by discontinuous contact between tires and the slope bearing bench when the vehicle runs at high velocity, and can cater to the requirements of accurate measurement of the vehicle.

Description

technical field [0001] The invention belongs to the technical field of vehicle weight measurement, and relates to a method for measuring dynamic vehicle weight and a dynamic vehicle weight measurement system. Background technique [0002] Vehicle transportation is a common mode of transportation in people's daily life, but illegal overloading of vehicles occurs from time to time, which may endanger the personal or property safety of other vehicles or pedestrians on the road. Therefore, it is necessary to measure the weight of vehicles driving on the road. In order to monitor whether it is overloaded. [0003] There are two commonly used vehicle weight measurement methods: static weighing method and dynamic weighing method. The static weighing method is to park the vehicle completely on the weighing platform for weighing. Although the weighing result is accurate, the weighing efficiency is low and cannot meet the requirements of high traffic efficiency. The dynamic weighing...

AI Technical Summary

Problems solved by technology

If the vehicle passes the weighing platform at a high speed, a large horizontal impact will be generated, making the weighing result of the dynamic weighing method less accurate and unable to meet the requirements of precise weighing

[0004] In addition, the level of the current weighing platform and the road surface, under the influence of factors such as vehicle vibration, road surface characteristics and installation accuracy, when the vehicle passes the weighing platform at high speed, it is difficult for the tires to contact the weighing platform all the way, and the higher the speed, the The contact time of the tire with the weighing platform has more uncertainty, so the measurement is less accurate
