Introduction Electricalfiresareoneofthemostcommontypesoffireaccidents.Theyposeasignificantrisktohumanlifeandproperty,andaredifficulttodetectusingconventionalfiredetectiontechnologies.Conventionalmethodsrelyontheuseofsingle-sensordevicessuchassmokedetectors,heatdetectors,andflamesensorstodetectfires.However,thesedeviceshavelimitationsindetectingelectricalfires,astheyoftenfailtodetecthiddenfiresorfirescausedbyelectricalfaults.Inaddition,thesedevicescanalsogeneratefalsealarms,leadingtounnecessaryevacuations,whichcanbecostlyanddisruptive. Multi-sensordatafusiontechniqueshaveemergedasapromisingsolutiontothesechallenges.Byintegratingdatafrommultiplesensors,theaccuracyandtimelinessoffiredetectioncanbesignificantlyimproved.Multi-sensordatafusiontechniquescandetecthiddenfiresandelectricalfaults,andcanalsoreducefalsealarmsbycross-validatingdatafromdifferentsensors.
