At present,the logistics package processing procedures of entity enterprises are various and mainly rely on manpower.Aiming at the problems of low weighing efficiency caused by single function of logistics equipment and manual static weighing,this paper designs a logistics dynamic weighing system based on STM32F103 series single chip microcomputer.The system design is based on STM32 chip,combined with power module,signal acquisition module,signal processing module and communication module,with the corresponding software design,to achieve the logistics quality information acquisition,data processing,data transmission,multi-platform supervision and other functions of dynamic weighing system.The design of the system focuses on the realization of dynamic weighing and multi-platform supervision function,which is convenient to form a digital management system.The field test shows that the system's processing efficiency of parcels can reach up to 3600 pieces per hour,which has a role in reducing costs and increasing efficiency for enterprises.
