Abstract: In view of the shortcomings of traditional automatic sprinkler system, such as long response time and large water loss, this paper proposes a research scheme of active automatic sprinkler system, which realizes the initiative and intelligence of automatic sprinkler system by new detection components, electric heating sprinkler, and algorithm programming. An experimental platform was built. Against corner fire, border fire and center fire, the system fire detection performance and sprinkler startup condition are analyzed. The experimental results show that the automatic sprinkler system can detect the location of the fire in the early stage, start the sprinkler head and its group in the corresponding position by active electric heating, put out the initial fire and reduce the water loss at the same time.

Key words: automatic sprinkler system, fire detection, active sprinkler system, electric heating sprinkler, water loss
