DEVICE FOR PREVENTING GAS LEAK FIRE / EXPLOSION INCIDENT USING GAS SENSOR AND METHOD FOR CONTROLING THE APPARATUS

摘要

The present invention relates to an apparatus which prevents fire and explosion incidents by gas leakage through detecting the leakage using a combustible gas sensor when fuel gas such as LNG, LPG, or H_2 is leaked, and associatedly controlling an alarm, a breaker, a ventilator, and a window; and to a method for controlling the same. The present invention provides an apparatus for preventing gas leakage explosion and fire incidents, which includes: a gas sensor which detects combustible gas; a detecting unit which amplifies and detects an electric signal detected by the gas sensor; and a control unit which controls the alarm, the breaker, and the ventilator on the basis of the detected signal. The present invention also provides a method for preventing a gas leakage explosion and fire incident, which includes the following steps: detecting the combustible gas using the gas sensor; comparing the concentration of reference gas with the concentration of the detected gas; generating an explosion danger warning when the concentration of the detected gas exceeds the concentration of the reference gas for a set time; and controlling the breaker and the ventilator on the basis of the concentration of the detected gas.
