Eddy Current Acquisition System Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Eddy current test systems require complex and time-consuming assembly and configuration of multiple components, leading to human error, radiation exposure, and high maintenance costs, particularly due to mechanical clutches that need adjustment in a 'hot shop' environment.
Innovation Solution
The MIZ-80/D eddy current acquisition system integrates key components into a single modular system with a 1-Wire communication bus and electronic clutch, reducing cable connections, automating component identification, and eliminating mechanical clutch maintenance, enabling faster setup and reduced radiation exposure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple separate components are assembled into an eddy current test system, then the system can be configured for different inspection missions, but the assembly process is time-consuming and prone to human error
Solution Approach 1:
The patent combines multiple separate components (acquisition instrument, probe cable slip ring, probe adapter, take up reel, probe pusher) into a single integrated eddy current test system. This integration maintains the ability to configure different inspection missions while eliminating the time-consuming assembly process of connecting multiple separate components through numerous cables and adapters.
Solution Approach 2:
The integrated system incorporates multiple functional components that can be configured for different inspection missions. The system includes a probe pusher for advancing probes, a take-up reel for retracting probes, an acquisition instrument for data collection, and a probe station for probe storage and exchange, all within a single multi-functional platform that can adapt to various inspection requirements.
2Adaptability or versatility
If multiple components are assembled manually, then the system can be configured for specific missions, but human exposure to radiation increases during assembly and configuration
Solution Approach 1:
By integrating all system components into a single unit, the patent eliminates the need for personnel to manually assemble and connect multiple separate components in the radiation environment. The integrated system can be configured for different missions without requiring human entry into the hot shop, thereby reducing radiation exposure.
3Reliability
If a mechanical clutch is used to maintain probe shaft tension, then the shaft remains taut between pusher and reel, but maintenance and adjustment require hot shop environment and radiation protection
Solution Approach 1:
The patent replaces the mechanical clutch with an electronic clutch system. This substitution eliminates the need for mechanical parts that require manual adjustment and maintenance in the radiation environment. The electronic clutch can be maintained and adjusted externally without requiring hot shop entry, thereby improving ease of repair while maintaining reliable probe shaft tension.
4Reliability
If thirteen cable connections are used in traditional systems, then all components can be connected, but setup time increases and system complexity increases
Solution Approach 1:
The patent integrates multiple cable connections into a single unified connection system. Instead of requiring thirteen separate cable connections between components, the integrated design provides a single connection point that establishes all necessary electrical and data connections, thereby reducing system complexity and setup time while maintaining full component connectivity.
5Adaptability or versatility
If manual assembly and configuration is performed, then components can be assembled for different missions, but human error in assembly and configuration increases
Solution Approach 1:
By providing a single integrated system rather than multiple separate components requiring manual assembly, the patent eliminates human error associated with connecting components. The integrated design ensures correct assembly and configuration for different missions without requiring manual intervention, thereby improving assembly accuracy and reliability.

AI summary
An eddy current acquisition system integrates traditional elements of a nuclear steam generator tubing inspection into a single modular system comprising three subsystems: the take-up reel subsystem, the acquisition instrument, which is located in the hub of the take-up reel, and the pusher head subsystem. All of the control electronics are respectively enclosed in bases of the pusher head and the take-up reel subsystems in water-resistant and dust proof enclosures. Simplified setup is achieved by employing a single communication bus linking an identification (“ID”) chip in each component to a host computer. The ID chip stores and reports product part numbers, descriptions and serial numbers and revision or upgrade status and may also store statistical information such as device duty cycles, performance statistics, repair history, and the like. It also enables auto-fill of product information into firmware of the acquisition instrument, including probe pusher ID, take-up reel module ID, eddy current instrument ID, probe product ID and their serial numbers. It also provides automated inventory management by updating the probe inventory database based when probes are attached and detached from the system. Also implemented in the acquisition instrument module is a real-time landmark detection firmware system.
