  优发 AbstractVRLA battery oftenused back—uppower powersupply system.It aDCpower supply mainpower supply system fails,the secondary power system maintains its normal operating system powered VRLAbattery actualcapacityproviding dischargeprocess,has ahighly significance makingsure electricalequipment work regularly.In most cases,battery management detect adischargetest,or replacingbatteries periodically substation,优发首页inorder protectelectric equipment from appearing faults due capacity.Butadischarge test spendmuch time replacingbatteries results awaste economiclosses.To solve problems,thepaper designs completesareal-time online system batteries.The system consists dataacquisition unit,SBUS conversion unit,the primary controller unit monitoringhost unit,with using sensor technologycomputer technology modemcommunication technology comprehensively.Battery sensors currentsensors detectbatteries operating parameters real-time batteryacquisition unit.The SBUS serial bus communication protocol has been used batterysensors,and sensorsconnected together via communication lines SBUSconverters.The reliable datatransmission SBUSeffectively.The system uses aSBUS conversion unit,which Can change batteryparameter signal serialdata stream, which Can receiveddirectly primarycontroller.The primary controller unit receives batteryparameters processesthem,then display LCDdisplay.Meantime, primarycontroller transmits battery parameters monitoringhost through GPRS wireless communication,and controllercompares battery parameters pre-setbattery parameter thresholds.If hasbeen detected detectingbattery parameters exceed pre-setbattery parameter thresholds,the controller giveawarning.Monitoring host receives battery datauploading from controllerstoresdata workingstatus algorithm,thesystem Can calculate residualcapacity deteriorationdegree batteries.Monitoringhost provides abnormal alarm function when battery parameters abnorma。
