Weighing-free AI intelligent identification truck overload estimation method, device and system

Abstract

The invention discloses a weighing-free AI intelligent identification truck overload estimation method, device and system. The method comprises the steps: firstly, obtaining the average deformation coefficients of rear wheel truck tires of the same type of vehicles under different load capacities, and carrying out fitting to obtain a statistical data linear regression function model that the corresponding average deformation coefficients of the tires change along with the change of the load capacities; determining a truck load upper limit value and a multiple load value according to the trucktype, and substituting the truck load upper limit value and the multiple load value into the function model to obtain a corresponding truck overload tire deformation coefficient value and a multiple overload deformation coefficient value; and when the vehicle to be detected passes through the video detection point, calculating the average deformation coefficient of the rear wheel truck tire according to the deformation horizon length of the rear wheel tire and the radius of the truck tire, comparing the average deformation coefficient with a correlation numerical value, and judging whether thevehicle is an overload or multiple overload suspected vehicle. The invention aims to solve the problems of low cost, no lane guidance, no-dead-corner deploying and controlling intelligent monitoringoverload of various levels of highway networks, especially severe overload vehicles, in the aspects of technicality and economy.

Description

technical field [0001] The present invention relates to the field of traffic safety, in particular to a method for estimating overload of trucks with AI intelligent identification without weighing, as well as related devices and systems. Background technique [0002] Overloaded vehicles will cause great harm to traffic safety, environment and roads, especially bridge facilities, and the traffic management departments of domestic and foreign governments attach great importance to it. In recent years, my country's efforts to control excesses have also increased. At the entrance of the expressway, the overloading phenomenon has been controlled to a certain extent, but the construction and maintenance costs are relatively high, and a small number of semi-trailers pass through the toll booths by skipping or dragging the scale; non-toll roads have no toll ramps It is difficult to install weighing equipment. Even if it can be installed, the number of covered installations is large...

AI Technical Summary

Problems solved by technology

At the entrance of the expressway, the overloading phenomenon has been controlled to a certain extent, but the construction and maintenance costs are relatively high, and a small number of semi-trailers pass through the toll booths by skipping or dragging the scale; non-toll roads have no toll ramps It is difficult to install weighing equipment. Even if it can be installed, the number of covered installations is large, the maintenance management is complicated, and the investment is huge

Public security traffic police at all levels and transportation and road administration departments invest a lot of manpower and material resources every year to patrol the roads or set up inspection stations, but it is difficult to cover the road network and it is impossible to prevent it. The phenomenon of trucks exceeding the limit and overloading is still relatively serious, bringing universal traffic safety hazards
