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...

Examples

Embodiment Construction

[0044] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.

[0045] The present invention is illustrated by taking the 9 types of vehicles in the national standard, that is, six-axle trucks as an example. The monitoring system for real-time measurement of the total vehicle weight of the present invention includes TPMS, a measurement system for the contact length between the tire and the road surface, a calculation system for the total vehicle weight, and a real-time alarm monitoring system.

[0046] TPMS is used to measure the internal air pressure of each tire of the vehicle and send the pressure data to the calculation system of the vehicle's gross weight in real time.

[0047] The measurement system of the contact length between the tire and the road surface is used to measure the curvature data and distance data of each tire of the ...
