GAS LEAKAGE MONITORING METHOD AND ITS SYSTEM

摘要

Gas leakage monitoring method and system capable of ensuring safety of a gas utilization facility by visualizing invisible-to-naked-eye leakage gas and/o r flame of leakage gas. The gas leakage monitoring method is characterized in that a specific wavelength of a detected light caused by leakage gas and/or flame of leakage gas is collected in a space to be monitored, converted into an electronic image, amplified and then converted again into an optical imag e thus imaging the spatial intensity distribution of the specific wavelength. The gas leakage monitoring system is characterized by comprising a first mea ns for collecting a specific wavelength of a detected light caused by leakage g as and/or flame of leakage gas in a space to be monitored, a second means for converting the detected light into an electronic image, amplifying it and converting the electronic image again into an optical image, and a third mea ns for imaging the spatial intensity distribution of the specific wavelength.
