Ultrasound-based freight car adaptive load detection system and method thereof

Abstract

The invention discloses an ultrasound-based freight car adaptive load detection system, which comprises a main control processor, an ultrasonic sensor, a temperature sensor, a six-axis acceleration sensor, a car CAN bus, a communication module and a background data center, wherein the ultrasonic sensor, the temperature sensor, the six-axis acceleration sensor and the car CAN bus are connected withthe main control processor respectively; and the main control processor is connected with the background data center through the communication module. The invention also discloses an ultrasound-basedfreight car adaptive load detection method. In no load, ultrasonic signals are transmitted, returned signals are transmitted to the main control processor, and a measurement distance D is calculated;in load, ultrasonic signals are transmitted repeatedly, and a load distance D' is calculated; and according to a distance change amount deltaD, the load weight W is calculated. The system and the method disclosed in the invention has the advantages that mounting is convenient, acquisition is quick, the data are accurate, the cargo weight change and the car tilt condition can be detected and reported in real time, and remote management and supervision are carried out.

Description

technical field [0001] The invention relates to the technical field of load measurement, in particular to an ultrasonic-based truck self-adaptive load detection system and a method thereof. Background technique [0002] With the rapid development of the logistics industry, the phenomenon of overrunning and overloading of trucks has become one of the main reasons for disrupting public transportation order and endangering personal safety. Overrunning and overloading will cause the following problems: [0003] (1) A large number of road traffic safety accidents have been induced, causing huge losses to people's lives and property; [0004] (2) Serious damage to road infrastructure, causing huge losses to the country; [0005] (3) Cause the exhaust noise to seriously exceed the standard and pollute the environment; [0006] (4) Leading to vicious competition in the road transport market; [0007] In the traditional truck load detection method, one solution is to install the w...

AI Technical Summary

Problems solved by technology

[0003] (1) A large number of road traffic safety accidents have been induced, causing huge losses to people's lives and property;

[0004] (2) Serious damage to road infrastructure, causing huge losses to the country;

[0005] (3) Cause the exhaust noise to seriously exceed the standard and pollute the environment;

[0006] (4) Leading to vicious competition in the road transport market;

[0007] In the traditional truck load detection method, one solution is to install the weighbridge on the ground at the detection point, and the supervisor will weigh the truck as a whole; due to the high cost of the weighbridge, it cannot be installed anywhere, and the test results are not consistent with the real weight. There may be certain errors. At the same time, because the weighbridge needs to be fixed on the ground, it can only measure the load at that time, and it cannot be detected when loading and unloading at other times, which has caused certain difficulties in supervision;

[0008] Another solution is to install equipment on the vehicle body, generally using electronic rulers, laser sensors, reflectors, strain resistances, etc.; these methods are not only expensive, but also troublesome to install, requiring modification of the vehicle body, and cannot be widely used
