Synchronized Detector Grouping for Predictive Maintenance Data Collection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing equipment item diagnosis systems require pre-connected wires for synchronization of data from measuring instruments, limiting the ability to perform predictive maintenance on freely grouped detectors, as they cannot diagnose anomalies in unsynchronized data.
Innovation Solution
A data collection and analysis system with a communication unit and data acquisition unit that synchronizes data from detectors by setting acquisition timing and storage locations for each group, allowing for synchronization without pre-connected wires.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wires for synchronization are connected in advance to measuring instruments, then data synchronization is achieved, but device complexity and installation difficulty increase
Solution Approach 1:
The patent replaces the mechanical wire connection system with a wireless communication system. The data acquisition unit transmits data to the analysis unit via wireless communication, eliminating the need for physical synchronization wires while maintaining data synchronization through timestamp-based correlation and buffer management mechanisms.
Solution Approach 2:
The patent introduces a data buffer as an intermediary component between the data acquisition unit and the analysis unit. This buffer temporarily stores acquired data and manages data flow, enabling synchronization without direct wire connections by coordinating data retrieval timing between multiple detectors.
2Measurement precision
If data are acquired from all measuring instruments in a group in synchronization, then predictive maintenance accuracy improves, but system complexity increases
Solution Approach 1:
The patent applies preliminary action by pre-allocating data buffers and pre-configuring acquisition parameters for each detector before data collection begins. The system pre-establishes the data flow paths and buffer allocation schemes, so that when data acquisition starts, all detectors can operate in synchronization without requiring complex real-time coordination, thus improving measurement precision while controlling system complexity.
3Adaptability or versatility
If detectors are freely grouped afterward without pre-connected wires, then adaptability improves, but data synchronization becomes difficult
Solution Approach 1:
The patent implements dynamics by making the detector grouping configuration flexible and changeable after system deployment. The data acquisition unit can dynamically assign detectors to different groups based on operational needs, and the buffer management system adapts to accommodate these changes while maintaining data synchronization through configurable buffer allocation and timestamp-based correlation.
Data Source
AI summary
A data collection and analysis system includes a communication unit and a data acquisition unit. The communication unit collects data indicating an internal state or operation state of an equipment item. The data acquisition unit acquires, from the communication unit, the data synchronized for each of groups according to setting information, the setting information being information in which the groups, a data acquisition timing, and a storage location of the data are set for a channel allocated to the data to be acquired from the equipment item, each of the groups bringing together a plurality of the channels, the data acquisition timing being a timing at which the data are acquired from the communication unit.
