STM32 基于的输送带保护控制器设计 Abstract Withtheincreasingdemandforautomaticproductionlines,conveyorbelts havebecomeoneofthemostcommonly-usedtransportationequipmentin factories.However,conveyorbeltsaresubjecttovarioustypesofdamagedue towearandtearovertime,whichcancausemajorsafetyrisksandproduction losses.Inthispaper,weproposeadesignofaconveyorbeltprotection controller,whichisbasedontheSinglechipMicrocomputer(STM32).The controlleriscapableofmonitoringtheconveyorbeltinreal-timeandcan automaticallydetectvarioustypesoffaultsintheconveyorbelt,suchas slipping,tearing,anddeviation.Thecontrollercanalsoautomaticallyadjust thespeedoftheconveyorbelttopreventfurtherdamage. Keywords:STM32,conveyorbeltprotectioncontroller,real-timemonitoring, faultdetection,speedadjustment Introduction Conveyorbeltsarewidelyusedinvariousindustries,suchasmining,food processing,andmanufacturing.However,thesafetyandreliabilityofconveyor beltshavealwaysbeenaconcern.Inordertopreventaccidentsanddamage totheequipment,itisnecessarytomonitortheconveyorbeltcontinuously andtakeappropriateactionsincaseofanyfault. Therearevarioustypesofconveyorbeltprotectioncontrollersavailableinthe market,butmostofthemarelimitedintheircapabilities,andcannotprovide real-timemonitoringorautomaticfaultdetection.Inthispaper,weproposea conveyorbeltprotectioncontroller,whichisbasedontheSTM32 microcontroller.Thecontrollercannotonlyprovidereal-timemonitoringof theconveyorbeltbutalsodetectvarioustypesoffaultsandadjustthespeed oftheconveyorbelttopreventfurtherdamage.
