Research On Anti-collision Algorithm Of RFID Tags In Smart Supermarkets Based On Internet Of Things Era

Internet of Things is hailed as the third information revolution in human history.In the context of Internet of Things,intelligent logistics emerged,and it quickly became a new means for western countries to transform their economic development,protect resources,ecology and the environment.As a new type of logistic industries,the intelligent logistic industry is of great significance for promoting the transformation and development of the green economy,optimizing the government's macro-control,and building Chinese economic upgrade.The introduction of RFID technology into traditional supermarkets to build smart supermarkets in the context of intelligent logistics is the development trend of future supermarkets.From the basic theories of Internet of Things and intelligent logistics,this paper studies smart supermarkets.Firstly,it analyzes the shortcomings of traditional supermarkets.Based on the two basic concepts of Internet of Things and intelligent logistics,this paper discusses and compares the present researches of smart supermarkets,and analyzes the advantages of introducing RFID technology into traditional supermarkets to build smart supermarkets.Secondly,on the basis of analyzing the principle and composition of smart supermarkets,the biggest problem in building smart supermarkets is the RFID tags collision problems.Finally,by analyzing the principle of the probabilistic anti-collision algorithm and the deterministic anti-collision algorithm,an improved lock-bit dual prefix probe anti-collision algorithm is proposed for the environment characteristics of smart supermarkets,and the workflow of the algorithm is designed.The feasibility and applicability of the algorithm are proved by simulation.
