Design And Application Of Active RFID Low Power And Location Technology

With the scientific research institutes,technology companies,catering companies valuable instruments and equipment more and more,such as spectrum instruments,signal sources and other valuable instruments and equipment,catering companies,ordering the use of tablet computers and other handheld electronic devices.With the development of society,this kind of material is gradually increasing the number of electronic equipment of metal,using the deployment of more and more frequent,the use of degrees of freedom is more and more high,in this case the online management of these assets is more important.However,the above electronic equipment uses traditional passive RFID management,which has the problems of short identification distance,easy to be blocked by metal instruments,difficult on-line positioning and unreliable anti-theft alarm.In the Internet of things technology,the integration degree of active RFID(Radio,Frequency,Identification)is higher and higher,and the cost is decreasing gradually,which makes it get a great deal of application.However,the active RFID has the problems of high power consumption,short maintenance cycle,and the contradiction between the online positioning accuracy and the cost.The technical characteristics of this subject fully research of active RFID,such as signal radiation,strong energy,in the reflection of the characteristics of occlusion,used in certain assets online positioning,monitoring,security,alarm and other occasions,it is difficult to achieve the passive tag.At the same time,aiming at the problems of high power consumption,short maintenance cycle and positioning application of active RFID,the project solution is studied.In hardware,power consumption is reduced through chip selection,low power chip circuit design,high performance microstrip antenna design,and other communication settings.At the same time,different heartbeat cycles are designed according to the application sites,as well as software controlled deep sleep and wake algorithms.According to different application occasions,the use of appropriate anti-collision algorithm,effectively reduce the probability of communication collisions,reduce the number of communications retransmission,saving energy consumption.At the same time according to the actual application,positioning strategy and positioning algorithm of active RFID,in the hope of finding a balance between the positioning effect and power consumption,the cost of the system,to solve the problem of on-line positioning under different application conditions.Through the above research design,this paper solves the engineering realization problem of active RFID with high power consumption,short maintenance period and positioning application.The important assets in the field of online positioning and automatic management system application and catering industry positioning and online ordering equipment security alarm application,for the first time active RFID low power consumption and low cost into an asset management industry and food industry ordering equipment management,realizes the online positioning,for these assets warehouse management,status query,burglar alarm and other functions,reduce the manual management pressure,improve the scientific level of automation,asset management,and is a combination of things active RFID low power technology and positioning technology in a certain industry and catering industry,technology and application of a good,and design a set of suitable for this two of the industry's operating efficiency,low cost,good performance of active RFID online positioning and automatic management system.
