Abstract

The invention provides an indoor gas leakage information acquisition method and a device thereof, and the method comprises the steps: receiving an indoor gas total concentration change curve in a timeset, obtaining a gas concentration change coordinate graph based on a time coordinate system, and enabling the gas concentration change coordinate graph to serve as first gas information; receiving an indoor infrared video in the time set, and obtaining an infrared spectrum change coordinate graph based on a time coordinate system and serving as second gas information; determining characteristicparameters of leaked gas and leaked gas according to a preset gas spectrum model based on a comparison result of the first gas information and the second gas information; and according to the concentration change curve of the indoor gas and the leaked gas, gas leakage information is determined through a preset gas quality change formula, and the gas leakage information comprises the gas leakage amount and the gas leakage position.

Description

technical field [0001] The invention relates to the technical field of laboratory gas protection, in particular to a method and a device for collecting indoor gas leakage information. Background technique [0002] At present, when the gas leaks in the laboratory, the existing technology mostly monitors it through sensors, which consumes a large number of sensors and monitors the gas concentration at multiple points, but the existing technology has the defects of inaccurate and high cost of monitoring gas leakage. Contents of the invention [0003] The invention provides a method for collecting indoor gas leakage information, which is used to solve the situation of laboratory gas leakage, the leakage information cannot be accurately determined, and the cost is high. [0004] A method for collecting indoor gas leakage information, comprising: [0005] According to the change parameters of the total indoor gas concentration change curve in a time set, the gas concentration c...
