R&D on an Embedded System of the Material Management for Internet of Things

A highly efficient design project on embedded system for Internet of Things (IOT) is presented for materials margin management system. As the key instruments of IOT, the acquisition and transmission of weight system data is based on embedded STC15W201S. RS485 bus and Ethernet are used to link microcontroller and PC which make a complete materials margin for real-time dynamic management system. Communication between host computer and instruments and software of host computer are provided to implement of weighting system. As the key technologies, communication between PC and Ethernet, weighting calibration and data filtering are discussed. Test results show that this embedded system can satisfy the design purpose to materials management for Internet of Things.
