The Application And Optimization Research Of RFID Sensors On The Internet Of Things Platform Of Intelligent Bookstore

News publishing industry in recent years the rapid development of application technology put forward higher requirements for industry under the background of this wisdom bookstore iot platform arises at the historic moment,but because platform structures,shorter time,certain deficiencies in structure and application technology,especially the key data transmission level compared with the traditional wisdom bookstore to use RFID tags,RFID sensor with RFID tags and transmission function,can be applied to set up the wisdom of the Internet of things platform,so as to truly achieve wisdom Based on this background,this paper conducts an in-depth study and discussion on the optimization design of the Internet of things platform and the applicable RFID sensor design of the existing smart bookstore.The main research contents are as follows.(1)Discusses the development status of RFID sensor design and application at home and abroad,focuses on the comparison and analysis of the type differences and application scenarios of current RFID sensors,and analyzes and studies the antenna technology and theory involved in RFID sensor design.(2)For the initial set up news publications,networking platform overall structure and the key technology is applied to optimize,according to the characteristics of the current application platform process more cumbersome,design the framework of application platform more concise,and the perception layer and application layer USES zigbee network technology and other related technology to replace optimization,using is suitable for the application platform of the desiFID sensor can be combined under the premise that retain the advantages of RFID tags sensing function,compared with zigbee technology can greatly improve efficiency to reduce costs.(3)According to the principle of RFID sensor design,combining the instances of RFID sensor has been used in other industries,the design is suitable for the wisdom bookstore content networking platform for RFID sensor,based on the existing RFID technology,selection of microstrip antenna structure as the sending and receiving antenna,the antenna impedance and gain of parameters selection and the circular polarization,using Ansoft HFSS electromagnetic simulation software and the genetic algorithm for iterative calculation and simulation model.(4)Based on the design of the passive RFID sensor,a design method of the book dislocation alarm system is proposed,which USES the RFID sensor principle to design the electromagnetic excitation device,and USES Matlab guide software to design the main interface of the system.
