PURPOSE: An automatic fire extinguishing system is provided to efficiently extinguish fire by controlling a fire extinguisher and a gas circuit breaker through a signal detection of sensors for detection of fire. CONSTITUTION: An automatic fire extinguishing system comprises a temperature detection device(120), a gas detection device(140), a gas circuit breaker(220), a fire extinguisher(240), and a control device(400). The temperature detection device detects a temperature of a specific space. The gas detection device detects a gas concentration of the specific space. The gas circuit breaker opens and closes gas supply of a gas pipe. The fire extinguisher sprays a fire extinguishing agent through an outlet(260). The control device detects and displays current status of the temperature detection device, the gas detection device, the gas circuit breaker, and the fire extinguisher, determines fire breaking out and gas leakage based on a detection signal generated from the temperature detection device and the gas detection device, and blocks the gas leakage by controlling the gas circuit breaker and controls the gas circuit breaker and the fire extinguisher based on the determination in order to extinguish fire.
