Research On Storage Location Method Based On UHF RFID

With the advancement of the times and the development of science and technology,internet application in various fields has become increasingly widespread and has become a hot spot and focus of current research.As one of the upstream technologies of the Internet,RFID technology has many advantages such as low power consumption,fast reading and writing speed,large storage capacity,long storage period,high security performance,penetrating batch reading and global uniqueness etc..It is widely used in logistics,warehousing,retail,military,manufacturing and other fields.Its market scale increases year by year,and keeps rapid development.In this paper,we learn RFID technology,we select the Korean PR9200 read/write chip to design a passive UHF RFID read/write module with small size,low cost and adjustable output power within a certain range,and then adopts the variable power read/write module.Combined with STM32F103CBT6 MCU and ESP8266 wireless WIFI to form an offline reader,plus Alien Higgs 3 electronic tag with frequency band 840-960 MHz,forming a distributed system,with variable power recognition and positioning algorithm,to build a complete warehouse location management system.The system only needs to install a few(three or more)readers and a computer to complete the retrieval and positioning of passive UHF RFID cargoes in a wide range,which has a volume compared with other indoor positioning systems.Tiny size,low cost,simple structure and easy installation etc advantages.The paper first gives an overview of RFID,introduces its development history,current situation at home and abroad,and future trends.It puts forward the research content,research ideas and research methods of this paper.Then it briefly describes the advantages and disadvantages of several.
