Piping State Analysis via Multi-Location Fluid Flow and Pressure Index

The patent segments the piping system into multiple measurement locations and divides deterioration types into distinct categories (local drastic deterioration vs. uniform gradual deterioration). By placing sensors at multiple locations and analyzing local flow characteristics separately, the system can detect localized deterioration that conventional single-point measurement methods would miss, thereby improving both measurement precision and prediction reliability.

The patent transitions from single-point measurement to multi-location measurement, adding spatial dimensionality to the assessment. By measuring flow speed and pressure at multiple locations along the piping and comparing these measurements, the system creates a dimensional framework that enables detection of localized anomalies, significantly improving deterioration detection precision while maintaining prediction reliability.

The patent applies local quality by analyzing flow characteristics at specific locations rather than making blanket assessments of entire piping systems. By calculating flow speeds and pressure differences at individual measurement points and comparing them to establish localized deterioration indices, the system accurately identifies only those specific sections requiring renewal, preventing unnecessary replacement of sound piping and improving maintenance efficiency.

The patent utilizes parameter changes in fluid flow (flow speed and pressure variations) as indicators of deterioration. By monitoring changes in these physical parameters at multiple locations and comparing them against baseline values or threshold criteria, the system achieves precise deterioration state assessment, enabling accurate differentiation between piping that needs renewal and piping that remains serviceable, thus optimizing maintenance productivity.

The patent employs universal, multi-functional sensors that can measure both flow speed and pressure at each location. By using sensors that perform multiple measurement functions rather than separate specialized sensors for each parameter, the system reduces overall device complexity while maintaining the capability to conduct multi-location measurements for high-precision deterioration detection.

The patent uses the flowing fluid itself as an intermediary medium to transmit information about piping conditions. By measuring flow characteristics (speed and pressure) of the fluid already present in the system, the method avoids the need for complex direct contact sensors or intrusive measurement devices, thereby reducing system complexity while achieving high precision in determining internal piping state through indirect but accurate fluid-based measurements.
