RFID Sewer Markers for Precise Pipe Liner Localization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for renovating pipelines and sewer systems are hindered by the time-consuming and error-prone nature of length measurements, and the unreliable use of radar technology for localizing areas to be renovated.
Innovation Solution
A method involving the mounting of RFID transponders as markers at specific areas within the pipeline or sewer system, allowing for precise localization using an RFID reader, and enabling accurate renovation by detecting these markers even under a pipe liner.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If length measurement is used during inspection and renovation, then the position of areas to be renovated can be determined, but the process becomes time-consuming and error-prone
Solution Approach 1:
Markers with RFID transponders are mounted on the sewer infrastructure in advance during inspection phases. This preliminary action stores position information that can be quickly retrieved during renovation operations, eliminating the need for time-consuming length measurements while maintaining high position determination accuracy.
2Measurement precision
If radar technology is used to detect areas to be renovated, then localization can be achieved, but the method is unreliable and can misinterpret voids as side inlets
Solution Approach 1:
Physical markers with RFID transponders are introduced as intermediary objects that provide unambiguous position information. These markers serve as reliable mediators between the inspection/renovation system and the sewer infrastructure, eliminating the ambiguity and misinterpretation problems associated with radar-based detection methods.
3Reliability
If markers with RFID transponders are mounted to specific areas, then precise and reliable localization is achieved, but the device complexity increases
Solution Approach 1:
The patent employs simple, inexpensive RFID transponder markers that can be easily mounted and replaced. These disposable or temporary markers provide high reliability for localization without requiring complex permanent installation systems, thus achieving reliable localization while minimizing device complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution provides a reliable and accurate means to locate predetermined areas within the sewer system, ensuring precise and error-free renovation processes, even when areas are covered by a pipe liner.
Implementation Method 1
the marker comprises an RFID transponder... an inspection and/or maintenance system, which has an RFID reader, is moved or advanced in the pipeline and/or sewer system until the RFID reader detects the RFID transponder
Data Source
AI summary
A method for mounting a marker to a specific area in a pipeline and/or sewer system, wherein an inspection and/or maintenance system in the pipe-line and/or sewer system is brought into the region of the specific area, and the inspection and/or maintenance system mounts the marker to the specific area, wherein the marker comprises an RFID transponder, is provided. A method for detecting a marker in a pipeline and/or sewer system, a method for renovating a portion of a pipeline or sewer system, and devices for mounting the marker at the predetermined area in the sewer and for detecting the mounted marker are also provided.
