A monitoring system and monitoring method for real-time measurement of vehicle gross weight

Abstract

The invention discloses a monitoring system and a monitoring method for measuring the total weight of a vehicle in real time. The monitoring system includes a TPMS, a measurement system for the contact length between the tire and the road surface, a calculation system for the total weight of the vehicle, and a monitoring system for real-time alarm; the monitoring method It mainly includes the following steps: TPMS measures the air pressure inside each tire of the vehicle; the measurement system of the contact length between the tire and the road measures the curvature data and distance data; Contact patch, weight per tire, axle load per axle and gross vehicle weight; a monitoring system with real-time alerts transmits data to drivers and regulators. The invention has the characteristics of high precision, stable system, convenient installation and operation, can strengthen the supervision of vehicle overloading and overrunning violations, reduce the overload damage of roadbed and road surface, reduce the maintenance cost of road bridges, and has wide application prospects.

Description

technical field [0001] The invention relates to the technical field of Internet of Vehicles, in particular to a monitoring system and a monitoring method for real-time measurement of vehicle gross weight. Background technique [0002] In recent years, with the development of the market economy, the road transportation industry has also developed rapidly, and the number and cargo capacity of various freight vehicles have increased year by year. From 2008 to 2017, the proportion of road freight volume rose from 74.1% to 78%. What comes with it is that the phenomenon of vehicle overloading and exceeding the limit is very common. When the market operation capacity cannot meet the transportation demand, car owners often overload and exceed the limit in order to pursue economic interests, which in turn brings a series of problems. According to the data, when the overload rate is 10%, the road surface damage rate increases by 46%, and the service life is shortened by 32%. Vehicle...

Problems solved by technology

This method can only be used for random inspection, which is time-consuming and inefficient, and the installation and operation of portable weighing instruments are even more troublesome.

Dynamic weighing is mainly based on axle load detection, allowing vehicles to pass through the axle load weighing platform at a certain speed to achieve the purpose of dynamic weighing, and the time for vehicle tires to pass through the platform is very short, due to some interference factors, such as tire driving force, vibration load, etc. , so the force acting on the weighing platform is not the actual weight of the vehicle, the measurement accuracy is low, and it is difficult to implement overload control in remote areas where underground weighing equipment cannot be laid

[0004] At present, the weight-based toll system based on dynamic weighing is generally used to control over-limit and overloading. Most of these traditional weighing methods need to establish large-scale inspection stations on the main road, which has the following disadvantages: the fixed inspection equipment for weighing is greatly restricted by the station, and cannot Real-time detection and identification of illegal over-limit transport vehicles

The detected vehicles are relatively concentrated, the measurement accuracy error is large, the detection efficiency is low, it is easy to cause traffic jams, and the vehicles are easy to bypass inspections, etc.

With the development of the transportation industry, traditional weighing methods can no longer meet the current needs
