Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Remote meter reading devices, such as gas meters, often experience deviations between visual and remote readings due to desynchronization or initial reading errors, which can be attributed to fraud or errors in the mechanical totalizer, posing challenges in initialization.
Innovation Solution
A method involving photographing the meter and remote reading device to extract identification information and initialization values through form recognition processing, ensuring correct sensor positioning, and storing this information in a database, with pattern recognition and image analysis to verify accurate placement and initialization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If remote reading devices are deployed to automatically read meter measurements, then productivity and operational efficiency are improved, but initialization errors and reading deviations occur due to lack of synchronization with mechanical totalizers
Solution Approach 1:
The patent applies preliminary action by capturing an initialization photograph of the mechanical totalizer before deploying the remote reading device. This photograph serves as a reference record of the initial reading, allowing the system to synchronize and validate subsequent remote readings against this pre-established baseline, thereby preventing initialization errors and fraud.
Solution Approach 2:
The patent uses copying by creating a digital photograph copy of the mechanical totalizer's initial reading. This visual copy is stored and used for comparison with remote reading data, enabling verification of reading accuracy without requiring physical access to the meter, thus maintaining measurement precision while enabling remote operation.
2Measurement precision
If visual inspection of mechanical totalizers is performed to verify readings, then measurement precision is improved, but time consumption and operational efficiency deteriorate
Solution Approach 1:
The patent replaces the mechanical process of manual visual inspection with an automated digital photographing and image processing system. The terminal device captures the totalizer reading via photograph, and automated processing extracts and validates the initialization value, eliminating the need for manual visual verification while maintaining accuracy and reducing time consumption.
Solution Approach 2:
The system applies self-service by enabling the terminal device to automatically capture, process, and store the initialization photograph without requiring manual intervention for reading extraction. The automated image processing and validation procedures allow the system to verify readings independently, freeing operators from time-consuming manual inspection tasks.
3Reliability
If detailed photographing and image processing procedures are implemented to ensure correct sensor positioning and initialization, then reliability and reading accuracy are improved, but device complexity and processing requirements increase
Solution Approach 1:
The patent applies universality by designing the terminal device to perform multiple functions: capturing initialization photographs, processing images to extract totalizer readings, validating data accuracy, storing records, and verifying sensor positioning. This multi-functional approach consolidates complex operations into a single device, reducing overall system complexity while maintaining high reliability through comprehensive initialization procedures.

AI summary
The invention relates to a method of initializing a remote-reading device intended to be hooked up to a meter (C). The remote-reading device and the meter each exhibit a visible identifying marking (IC, IB). When the remote-reading device is fitted, - a photograph of the meter and of the remote-reading device is taken so that the markings of one and the other are visible therein with the value displayed by the mechanical totalizer (TM) of the meter, - a shape recognition processing (OCR) is implemented on the photograph. A shape recognition processing (OCR) is implemented on the photograph, and - these various items of information are stored in a data base (6).
