Image-Guided Paver Hopper Control for Uniform Material Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The accuracy and efficiency of operations in paver construction are hindered by manual visual measurements, leading to misoperations, material uneven distribution, and high labor intensity, particularly in coordinating the feeding car with the hopper and material distribution chute.
Innovation Solution
A paver control system with an image acquisition device, controller, and execution device that automates the operation of the hopper, guiding the feeding car, and material distribution based on image information, reducing reliance on manual visual measurements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual visual measurement is used to coordinate the feeding car with the hopper, then the operation method is simple, but the positioning accuracy is low and repeated operations are required
Solution Approach 1:
The patent replaces manual visual measurement with an image acquisition device (camera) that captures images of the feeding car and hopper. The controller processes these images to automatically determine positions and guide the feeding car, substituting mechanical/manual operations with optical detection and automated control.
Solution Approach 2:
The system enables self-service by allowing the paver to automatically guide itself through image-based positioning. The image acquisition device continuously monitors the feeding car's position, and the controller automatically adjusts the paver's movement without requiring manual intervention or external guidance.
2Manufacturing precision
If operators manually adjust material distribution in the chute, then the system structure is simple, but the material distribution uniformity is poor and paving quality is affected
Solution Approach 1:
The patent replaces manual visual inspection and adjustment of material distribution with an image acquisition device that captures images of the material in the chute. The controller analyzes these images to detect material distribution state and automatically adjusts the spiral material distribution mechanism, substituting manual mechanical adjustment with automated optical-based control.
Solution Approach 2:
The system implements feedback control by continuously acquiring images of the material distribution state in the chute, analyzing this information, and using it to automatically adjust the spiral material distribution mechanism. This closed-loop feedback ensures uniform material distribution without manual intervention.
3Productivity
If visual measurement is used for hopper operation, then the operation system is simple, but the operation efficiency is low and labor intensity is high
Solution Approach 1:
The patent replaces manual visual measurement and operation with an automated image-based control system. The image acquisition device captures images of the hopper and feeding car, and the controller automatically processes these images to control hopper operations, eliminating manual labor and significantly improving operational efficiency.
