Solution Overview
Problem
The management of tyres for large civil engineering vehicles in mines is inefficient due to the manual recording and updating of tyre positions, identifiers, and physical parameters, which can lead to errors and decreased productivity.
Innovation Solution
A method utilizing radio frequency identification (RFID) tags and physical parameter sensors on tyres, combined with an industrial vision system and a database, to automate the tracking and updating of tyre information during fitting and removal operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual recording and updating of tyre information is used, then the system complexity is low, but the productivity and reliability of tyre management deteriorate due to errors and time-consuming operations
Solution Approach 1:
The handling equipment is equipped with multiple detection systems (video acquisition, RFID readers, parameter sensors) that serve multiple functions: identifying the vehicle, detecting the tyre to be replaced, reading tyre identifiers, and monitoring physical parameters. This multi-functionality resolves the contradiction by automating tyre management operations, significantly improving productivity while the integrated nature of the system manages complexity through unified equipment.
Solution Approach 2:
The system enables automatic identification and tracking of tyres through RFID tags and visual identifiers that self-report their information. The handling equipment automatically detects and records tyre identifiers, vehicle identifiers, and position information without manual intervention. This self-service approach improves productivity by eliminating manual recording errors and time-consuming operations, while the automation handles the complexity of data collection and database updates.
2Measurement precision
If manual tyre identification and position tracking is performed, then the equipment cost is low, but the measurement precision and reliability of tyre monitoring deteriorate
Solution Approach 1:
The patent replaces manual mechanical identification methods with automated detection systems. Video acquisition systems capture visual identifiers on tyres and vehicles, RFID readers electronically detect tyre identifiers without physical contact, and parameter sensors automatically monitor physical conditions. This substitution dramatically improves measurement precision and reliability of tyre position identification, while the integrated detection systems manage the complexity through automated data processing and database integration.
Solution Approach 2:
RFID tags and visual identifiers serve as intermediaries between the tyre and the detection system. These passive elements carry identification information that can be automatically read by RFID readers or captured by video systems, enabling precise tyre identification without complex active sensors on the tyre itself. This intermediary approach improves measurement precision while keeping the detection system complexity manageable through standardized reading and recognition processes.
