Abstract

The invention provides a pyrolytic particle fire detection method and detector, and relates to the technical field of fire detection, and the method comprises the steps: firstly obtaining a plurality of parameter data of pyrolytic particles and / or an environment where the pyrolytic particles are located in a closed space of the pyrolytic particle fire detector; then judging whether each parameter datum exceeds a corresponding preset threshold value or not; if each piece of parameter data does not exceed the corresponding preset threshold value, performing fusion processing on all the parameter data by using a weight algorithm fusion technology to obtain parameter fusion data; and finally, based on the parameter fusion data and a preset pyrolysis particle alarm threshold, obtaining a pyrolysis particle fire detection result. According to the invention, a real and effective pyrolytic particle fire detection result can be obtained by fusing various parameter data by adopting a weight algorithm fusion technology, the early warning accuracy is improved, and extremely early detection and early warning of the fire can be realized.

Description

technical field [0001] The invention relates to the technical field of fire detection, in particular to a pyrolysis particle fire detection method and a detector. Background technique [0002] The heat generated in the early stages of an electrical fire can cause the thermal decomposition of the outer insulation layer of the wire, which in turn produces pyrolytic particles. The existing electrical fire protection technology uses pyrolytic particle detectors to monitor changes in the concentration of pyrolytic particles in the protected area for early detection and early warning of fires. However, this detection method only takes the concentration of pyrolysis particles as the influencing factor for early warning, and the accuracy of early warning is low, so it is impossible to achieve very early detection and early warning of electrical fires. Contents of the invention [0003] The purpose of the present invention is to provide a pyrolysis particle fire detection method a...
