Abstract：Aimingatthe lack of securityofasingle password lock and the diversificationof unlocking methods，this paper proposes amulti-functional intellgent electronic lock with STM32F103C8T632-bit microcontrollerasthecontrolcore. Theelectroniclockitegratesfourriicationmethods：passord，ICcard，ingerprintandWi-Fiandfurtheriproesthe security ofthedoorlock throughhierarchical permision，auditfunctionandalarmfunction.Thedoorlock is intheusemode by default，adthepassword，ICcardandfingerprintcanbeunlockednormall.Whentheulockingfails，thenumberofauditsis automaticallyaccumulated，andthecumulativefailureof3ormore timeswillocktheOLEDscrenandtrigger thealam.The usercanentertheadministratormodebyenteringtheadministratorpasswordthroughtheinterface，andthenaddordelete the userinformationofthepassword，ICcardandfingerprint.Inadition，thedoorlockhasanetwokingfunction：aftertheguest preses thenetworkingfunctionbuton，theMicrocontrolerUnit（MCU）isconnectedtothecloudplatformthroughtheESP8266 module.Theowneropens themobile phoneAPP，and theAPPautomaticallyconnects tothecloud platform torealizeremote unlocking operation.
