Grooved Rail RFID Identification Under Covered Track Conditions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rail identification methods, such as rolling marks and hot stamping, become illegible due to corrosion and are analog, complicating digital capture and integration into infrastructure databases, especially in covered tracks where traditional markings are obscured by construction materials, impairing traceability and maintenance.
Innovation Solution
A grooved rail with an RFID transponder attached directly to the track head or guide head, protected by epoxy resin, allowing wireless detection even under coverings, combined with optically detectable identifiers for redundancy, ensuring reliable identification and tracking in real-time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional marking methods (rolling marks and hot stamping) are used on rails, then complete traceability of the rail can be achieved, but the markings become illegible after a few years due to corrosion and are obscured by construction materials in covered tracks
Solution Approach 1:
The patent replaces mechanical marking methods (rolling marks and hot stamping) with an RFID transponder system. The RFID transponder contains a chip that stores rail identification data and can be wirelessly read without physical contact, eliminating the problem of corrosion and obscuration that affects traditional markings.
Solution Approach 2:
The patent introduces an RFID transponder as an intermediary carrier for rail identification data. Instead of marking the rail surface directly, the identification information is stored in the transponder, which can be read wirelessly through the rail structure, thus avoiding the problem of markings becoming illegible.
2Reliability
If traditional marking methods are used, then rail identification is possible, but digital capture and integration into infrastructure databases is complicated
Solution Approach 1:
The patent replaces analog marking systems with a digital RFID transponder system. The transponder stores identification data in digital format that can be automatically read and integrated into infrastructure databases, eliminating the need for manual data entry and simplifying digital capture processes.
3Stability of the object's composition
If rails are covered with construction materials in covered tracks, then track stability is improved, but identification and maintenance of rails becomes difficult
Solution Approach 1:
The patent uses wireless RFID reading technology to identify rails without requiring physical access to the rail surface. The reader can detect the transponder through the covering materials, allowing identification and maintenance operations to proceed without removing the track covering.
Solution Approach 2:
The RFID transponder acts as an intermediary that enables communication between the identification system and the rail infrastructure without requiring direct contact with the rail surface. This allows rails to remain covered while maintaining identification capabilities.
4Extent of automation
If RFID transponder is attached to the rail, then wireless identification is enabled, but the attachment method must ensure reliability under demanding conditions
Solution Approach 1:
The patent specifies that the transponder should be attached to the rail head or guide head, positioning it in an area that is more accessible for reading while ensuring reliable attachment. The attachment method is designed to withstand the dynamic conditions of rail traffic and environmental factors.
