Method and system for monitoring automobile load based on intelligent tire pressure gauge

Abstract

The invention relates to a method and system for monitoring an automobile load based on an intelligent tire pressure gauge. The method comprises the following steps: acquiring the temperature data of the gas in a tire sensed by a temperature sensor and the pressure data of the gas in the tire sensed by a pressure sensor; acquiring the exradius of a tire inner tube, the inradius of the tire inner tube, the major semi-axis when the tire is pressed, and the minor semi-axis when the tire is pressed; acquiring the initial tire pressure data of the tire and the temperature data of the gas in the tire; acquiring the changes in the volume of the tire before and after the tire is pressed; obtaining the load data of the tire according to the changes in the gas temperature before and after the tire is pressed, a Clapeyron equation and the acquired parameters; and monitoring the automobile load through the automobile load data. According to the method and the system for monitoring the automobile load based on the intelligent tire pressure gauge disclosed by the invention, a self-load measuring system is adopted to perform weighing, and has both the accuracy of static weighing and the real-time performance of dynamic weighing. On the premise of guaranteeing high accuracy, real-time load measurement is performed through the automobile sensor and some fixed parameters of the automobile, and overload or eccentric load of an automobile can be judged at any moment.

Description

technical field [0001] The invention relates to a vehicle load monitoring method and system, in particular to a vehicle load monitoring method and system based on an intelligent tire pressure gauge. Background technique [0002] In recent years, the phenomenon of over-limit and overloading of road transport vehicles in my country is very common. In some areas, freight vehicles will have a certain degree of over-limit and overloading. In order to suppress the phenomenon of vehicle overloading, extensive research has been carried out on vehicle overload detection technology at home and abroad. According to the classification of detection methods, there are mainly two methods, one is static weighing; the other is dynamic weighing. [0003] Static weighing methods include: vehicle load detection based on fixed detection stations, etc., the principle is simple and the weighing is accurate. [0004] There are two main types of dynamic weighing methods: separate type and vehicle-m...
