The term "large space site" refers to a place with a clearance height greater than 8m in civil and industrial buildings, and a clearance height greater than 12m in warehouse buildings. Large space intelligent AC active control sprinkler systems are composed of intelligent fire extinguishing devices (large space intelligent fire extinguishing device; automatic scanning water jet fire extinguishing device; automatic scanning water jet high altitude water cannon fire extinguishing device), signal valve groups, water flow indicators and other components, as well as pipelines and water supply facilities. They can automatically detect the fire location and actively spray water in the event of a fire. Large space intelligent fire extinguishing device Large space intelligent auto-sprinklerdevice The fire extinguishing spray surface is a circular surface that can actively detect the fire location and activate the nozzle to spray water for extinguishing. The intelligent automatic sprinkler system consists of ① intelligent infrared detection component; ② Large space and large flow nozzle; ③ The solenoid valve group consists of three parts. The intelligent infrared detection component, large space and large flow nozzle, and solenoid valve are all independently set. The standard large space intelligent fire extinguishing device is a large space intelligent fire extinguishing device with an installation height of 6~25m, a protection radius of ≤ 6m, and a water spray flow rate of ≥ 5L/s. The automatic scanning sprinkler device is an intelligent automatic scanning sprinkler device with a fan-shaped surface, consisting of ① intelligent infrared detection components; ② Scanning water jet nozzle; ③ Mechanical transmission device; ④ The solenoid valve group consists of four main parts. Among them, intelligent infrared detection components and scanning water jet nozzles
