Title:
GAS MONITORING PROGRAM, SYSTEM, RECORDING MEDIUM, AND METHOD
Document Type and Number:
WIPO Patent Application WO/2017/179599
Kind Code:
A1
Abstract:
The present invention continuously monitors gas leaking from piping equipment and predicts a maintenance time for the piping equipment. An information processing device (computer) in this system carries out: a step (E3) for calculating the product of the thickness and concentration of the leaking gas on the basis of infrared images, a step (E4) for estimating the gas leak position of the leaking gas in infrared images spanning a plurality of sequential frames on the basis of the images, a step (E5) for setting the gas type of the leaking gas by referring to distributed substance information for the piping equipment and comparing the same with the gas leaking position of E4, a step (E6) for setting a maintenance threshold for the product of the thickness and concentration of the leaking gas for the gas type set in E5, a step (E10) for estimating the amount of leaking per unit time on the basis of the infrared images spanning a plurality of sequential frames, and a predicted maintenance time calculation step (E11) for calculating a predicted time when the product of the thickness and concentration of E3 will exceed the maintenance threshold of E6 on the basis of the change over time of the amount of leaking per unit time of E10.
