Vehicle weight identification method, device and equipment based on simulation analysis and storage medium

Abstract

The invention discloses a vehicle weight recognition method, device and equipment based on simulation analysis and a computer readable storage medium. The method comprises the steps: acquiring the type, specification, tire pressure and vertical deflection of each tire in a target vehicle; determining a load model corresponding to the tire according to the type of the tire, and obtaining the load of each tire according to the specification, the tire pressure and the vertical deflection of each tire and the corresponding load model, wherein the load model is obtained by fitting the tire pressure and the tire vertical deflection based on a pre-established tire three-dimensional model corresponding to the tire type; and obtaining the weight of the target vehicle according to the load of each tire in the target vehicle. According to the technical scheme disclosed by the invention, non-contact, low-cost and high-efficiency vehicle weight identification is realized based on the type and specification of the vehicle tire pressure, the tire pressure and the vertical deflection.

Description

technical field [0001] The present application relates to the technical field of vehicle weight measurement, and more specifically, to a method, device, equipment and computer-readable storage medium for vehicle weight identification based on simulation analysis. Background technique [0002] In recent years, with the rapid development of the transportation industry, the problem of vehicle overloading has emerged in an endless stream. Overloaded vehicles will cause serious damage to traffic infrastructure such as roads and bridges. Therefore, more and more attention has been paid to the acquisition of vehicle weight. Not only is it of great significance to solve the problem of vehicle overloading, but also has a great impact on the establishment of intelligent transportation system and the maintenance and management of highway bridges. [0003] At present, the vehicle weight is often identified by means of weighbridge weighing, road dynamic weighing and bridge dynamic weighi...

AI Technical Summary

Problems solved by technology

[0003] At present, the vehicle weight is often identified by means of weighbridge weighing, road dynamic weighing and bridge dynamic weighing. The most important thing is to install sensors on the road, and use the sensors to measure the dynamic pressure of the wheels to obtain the weight of the vehicle. The installation and maintenance process needs to interrupt the traffic and excavate the road surface, which will cause hidden dangers to traffic safety, and because the sensor directly bears the weight of the vehicle , so the damage to it is relatively large, the life is relatively low, and the cost of weighing is increased. At the same time, due to the short contact time between the vehicle and the sensor, the road surface roughness has a greater impact on the weighing accuracy; bridge dynamic weighing still needs to be installed on the bridge Due to the complex environment of the sensor, it is difficult to install the sensor, and the weighing accuracy is greatly affected by the position of the sensor, sensitive to the lateral position of the vehicle, and poor in adaptability
