Bituminous mixture loading system based on machine vision and control method

Abstract

The invention discloses a bituminous mixture loading system based on machine vision and a control method. The system comprises a compartment type loading chamber, a loading door mechanism, a vehicle mobile platform and a machine vision control system. The vehicle mobile platform comprises a track flat plate, a longitudinal beam support, a roller mechanism and a roller driving mechanism. The machine vision control system comprises a control module, an illumination device, a rotating encoder, a pressure sensor, a camera and a photoelectric sensor. The control method comprises the first step of preparation work before loading of a bituminous mixture, the second step of setting of loading parameters of the bituminous mixture, the third step of rapid flat laying and loading, the fourth step of accurate flat laying and loading and the fifth step of unloading of a loading vehicle and scattered material recovery. According to the bituminous mixture loading system, design is reasonable, operation is easy and convenient, the using effect is good, the bituminous mixture loading process is controlled in real time, automatic flat laying type loading is achieved for the bituminous mixture, loading separation of the bituminous mixture is effectively reduced, and environmental pollution is reduced.

Description

technical field [0001] The invention belongs to the technical field of asphalt mixture loading control, and in particular relates to a machine vision-based asphalt mixture loading system and a control method. Background technique [0002] Nowadays, the loading of finished asphalt mixture in the asphalt mixing plant is still manually controlled. The operator in the control room of the batching plant observes the loading situation and controls the material door, directs the driver to move the vehicle through voice or signal lights, and fills the entire compartment one by one. The quality of manual loading is directly affected by the operator and the driver, and the operator needs to be close to the loading site of the asphalt mixture. The asphalt mixture is likely to bring hidden dangers to the health of the operator; The labor intensity is high, and it is easy to produce fatigue and cause production accidents. Therefore, it is necessary to effectively control the loading of...

AI Technical Summary

Problems solved by technology

Although this system avoids the influence of experience and fatigue on the loading quality to a certain extent, there are still some problems

First of all, the loading method is still the stockpile loading method. During the stockpile loading, the asphalt mixture rolls down along the stockpile surface to the bottom to produce segregation, which affects the homogeneity and service strength of the road surface; secondly, the control reliability of the loading process Low, different types of vehicles make the detection result of the depth of the cabin unreliable or the vehicle delays the parking position, resulting in the problem of overflow or lack of material
