Description

technical field [0001] The invention relates to a control system, in particular to an automatic fire alarm control system for subways. Background technique [0002] After entering the 1990s, my country's economy has entered a period of rapid development, urbanization has been accelerating, and urban buildings have also transitioned from decentralized low-density to centralized intelligence. The subway has become a gradually popular means of transportation. Due to the strong airtightness of the subway, once a fire breaks out, the subway station is like a big stove, and the subway passages, various ventilation pipes, and line shafts are all very conducive to the spread of the fire, which has caused great difficulties for fire fighting and rescue. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the above-mentioned prior art, and provide a kind of automatic fire alarm control system for subway. The automatic fire alar...
