Abstract：Theaccuratemonitoringofelevatorbrakeclearanceisdirectlyrelatedtothesafeandstableoperationofthelevator， whilethe traditionalmonitoring methods have problemssuchasinsuficientaccuracyandporeal-timeperformance.Therefore， amethodof elevator brakeclearance monitoringandearly warning basedoncapacitive grid technologyandimprovedlong short termmemory（LSTM）isproposed.Inthismethod，thecapacitancegridtechnologyisused tomeasuretheelevatorbrakeclearanceinrealtime，theelevatorbrakemonitoringtopological structurebasedonthecapacitancegrid technologyisconstructed， andthemonitoringplatformframeworkisbuilt，whichprovidesabasisforthedataacquisitionandanalysisofelevatorbrake.At thesametime，thedynamicatentionmechanismisintroducedintothetraditionalLSTMtoformanimprovedLSTMalgorith， whichcanidentifyandextract theabnormaldataofelevatorbrakeclearance，andefectivelyimprovethereal-time performance andpredictionaccuracyofthemodel.Theexperimentalresultsshow thatheproposed methodcanachieveanaccuracyof99.2% in identifying abnormal data，providing a new solution for the intelligent monitoring of gaps.
