Abstrct:Based on the multi-sensor data fusion method design power lithium battery fire prevention and control device,parallel,passive and active fire extinguishing the fire.Active fire fighting takes ambient temperature,CO concentration and smoke concentration as characteristic variables of fire detection.D-S data fusion algorithm integrates fire characteristic information of multiple sensors to form prevention and control decisions.Passive fire extinguishing realizes fire extinguishing agent injection at high temperature by closing the automatic control circuit of the fire extinguishing agent storage box,and realizes the injection of multiple fire extinguishing agent storage boxes through the high correlation of each fire extinguishing agent storage box,so as to achieve the effect of cooling and fire extinguishing.
