Design of Intelligent Fire Extinguishing System of Interior Large Space

摘要

With the constantly development of large space, the fire prevention of large space building is also increasingly important, but the traditional fire extinguishing system can not satisfy the requirements of fire extinguishing of interior large space. An intelligent fire extinguishing system of interior large space that using the single chip microcomputer SPCE061A as the main controller was designed. The fire location was detected with two-level flame sensors, and the detecting signal was transmitted to the single chip microcomputer SPCE061A. Two perpendicular stepper motors which was driven by the single chip microcomputer drive the fire extinguishing system rotating to achieve the space location of the fire. The test results shows that the system had low rate of false alarm, and the detection method is also simple and stabel, which can satisfy the requirements of early fire prevention in large space.
