Abstract: The paper introduced structure, working principle and module design of an automatic tracking and management system of model machine based on electronic tag and GPRS. The system reads data of model machine in electronic tag on the model machine through RF reader, and sends the data to main computer through GPRS module for manager browsering, so as to realize function of automatic tracking and management of model machine. The testing result showed that the system can help manager to find model machine quickly and improve management efficiency of model machine.
