Title:
GAS DETECTION SYSTEM AND GAS DETECTION METHOD
Document Type and Number:
WIPO Patent Application WO/2018/034236
Kind Code:
A1
Abstract:
Provided are a gas detection system and a gas detection method in which scanning by measuring beam is performed to acquire a two-dimensional gas distribution, wherein information which facilitates gas distribution-state understanding such as determining a gas leak location is output to a user on the basis of temporal history data of two-dimensional gas distribution information. The gas detection system comprises a light projection unit and light reception unit of measurement light, and calculates a gas measurement value on the basis of a light reception signal received by the light reception unit. The gas detection system includes: a control unit that controls a two-dimensional scanning measurement for acquiring two-dimensional gas distribution information consisting of two-dimensional coordinates indicating the location of a measurement point and a measurement value corresponding to the two-dimensional coordinates; and a calculation unit that calculates, on the basis of temporal history data of the two-dimensional distribution information which spans across multiple frames, where one frame consists of two-dimensional distribution information of one plane acquired by the two-dimensional scanning measurement, a statistic value such as an average value, a high concentration frequency, etc. for each measurement point, and that outputs two-dimensional distribution information of the statistic value.
