Method of detecting carrying capacity of vehicle by measuring deformation of steel plate, and measuring system

Abstract

The invention relates to the vehicle detection technology field, especially to a method of detecting the carrying capacity of a vehicle by measuring deformation of a steel plate, and also a measuring system. The method mainly comprises the steps: when a vehicle is in a static state, measuring deformation angles of vehicle steel plate springs when the vehicle has different loading capacities, and obtaining a corresponding relation between the loading capacities and the deformation angles; acquiring in real time state change data of the vehicle steel plate springs relative to a vehicle girder by means of a detector; calculating and obtaining instantaneous deformation angles of the vehicle steel plate springs in a vehicle static or driving state through the state change data; and obtaining the instantaneous vehicle loading capacity corresponding to the instantaneous deformation angles according to the corresponding relation between the loading capacities and the deformation angles of the vehicle steel plate springs. Through the deformation states of component parts of the vehicle when the vehicle has different loading capacities, the deformation angles of vehicle steel plate springs are utilized to serve as an index measuring the loading capacity of the vehicle to determine whether the vehicle is in a load-free state, fully loaded or overloaded and to calculate a loading capacity value of the vehicle. In this way, the loading capacity of the vehicle can be detected and monitored in a dynamic, real-time and accurate manner.

Description

technical field [0001] The invention relates to the technical field of vehicle detection, in particular to a method and a measurement system for detecting the load of a vehicle by measuring the deformation of a steel plate. Background technique [0002] For a long time, limited by objective conditions and driven by economic interests, the phenomenon of vehicle overload transportation has been very serious and common, which has posed a serious threat to road traffic safety and the transportation market, and has also induced a large number of road traffic safety accidents. Huge losses have been caused to life and property, and at the same time, road infrastructure has been seriously damaged and the service life of vehicles has been greatly shortened. [0003] At present, the load of the vehicle is generally monitored by a large electronic scale at a specific place. During the detection, the large electronic scale measures the weight of the entire vehicle loaded with goods, and...

[0002] For a long time, limited by objective conditions and driven by economic interests, the phenomenon of vehicle overload transportation has been very serious and common, which has posed a serious threat to road traffic safety and the transportation market, and has also induced a large number of road traffic safety accidents. Huge loss of life and property, at the same time, serious damage to road infrastructure and greatly shorten the service life of vehicles

[0003] At present, the load of the vehicle is generally monitored by a large electronic scale at a specific place. When detecting, the large electronic scale measures the weight of the entire vehicle loaded with goods, and then subtracts the current detected weight from the time when the vehicle is empty. The weight of the vehicle can be used to obtain the cargo weight of the vehicle; although this method has high accuracy, it can only measure the vehicle separately, and the efficiency is very low; Insufficient load capacity of vehicles causes waste of transport capacity

[0004] However, due to the lack of effective measurement technology for vehicle load, in the field of logistics and engineering transportation, vehicle owners or enterprises need to monitor the load weight in the whole process to identify whether there is any stolen goods and calculate the cost, which requires dynamic supervision of the whole process Vehicle load status; in fields such as muck removal and transportation, overloading not only damages roads, but also easily causes vicious accidents such as rollovers, resulting in casualties. take restrictive measures
