Loading Machine Control Device for Automatic Earth Removal Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing loading machine control systems require designation of an earth removal position, which hinders efficiency in automatic operation.
Innovation Solution
A loading machine control device that acquires position and azimuth direction information of both the loading machine and transport vehicle, specifies an earth removal position, and generates operation signals to move the bucket to that position automatically, eliminating the need for manual designation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual designation of earth removal position is required, then control accuracy is improved, but operation efficiency deteriorates
Solution Approach 1:
The loading machine control device automatically specifies the earth removal position by utilizing detected position information of the transport vehicle and azimuth direction information, without requiring manual designation. The system serves itself by computing the optimal earth removal position based on real-time vehicle location and orientation data, thereby eliminating manual intervention while maintaining positioning accuracy.
Solution Approach 2:
The patent replaces the manual mechanical designation process with an automated computational system. The control device uses detection units to gather position and azimuth data, then automatically computes the earth removal position through processing units, substituting human operation with electronic information processing and control algorithms.
2Productivity
If automatic operation is implemented without position designation, then operation efficiency is improved, but control complexity increases
Solution Approach 1:
The control device integrates multiple functions into a single system: it detects transport vehicle position, determines azimuth direction, specifies earth removal position, and generates control signals for the loading machine. This multi-functional integration automates the entire loading operation sequence without requiring separate manual designation steps, thereby improving efficiency while managing complexity through consolidation.
Solution Approach 2:
The control device acts as an intermediary between the transport vehicle detection system and the loading machine control system. It receives position and azimuth information, processes this data to determine the earth removal position, and then generates appropriate control signals, thereby bridging the information gap and automating the control process.
3Ease of operation
If earth removal position is automatically specified, then manual operation steps are reduced, but positioning accuracy may deteriorate
Solution Approach 1:
The control device continuously receives position information from detection units and uses this feedback to automatically specify the earth removal position. The system monitors the transport vehicle's real-time location and azimuth, adjusting the earth removal position specification based on current conditions, thereby maintaining accuracy while eliminating manual steps through continuous information feedback loops.
