The Research And Design Of Low Power Consumption RFID Active Tag

Radio Frequency Identification(RFID)has been gradually mature and gotten unprecedented development since 1980s.And we could find RFID technology in every field of our life and work.As a non-contactless identification technology,it brings much more convenience to social life and more value to industrial production.Firstly,we analyze the classification and characteristic of RFID technology,and then we talk about RFID application in different field.This thesis analyzes and designs the low power consumption problem in application.In order to reduce the power consumption of wireless communications products,to extend the working life of battery,it has been proposed to use low-power operating mode,reducing the redundancy wake of the low-frequency wake-up technology.Low-frequency wake-up signal is sen from wireless anchor,the tag device will analyzes the received signal and generates an interrupt or reset signal,the wireless terminal device will be waked from sleep mode.Low-frequency wake-up technology is used to reduce the power consumption of the wireless communication device,and it is very important to reduce the power consumption of the low-frequency wake-up own circuit.Depend on the low-frequency wake-up technology principle,low-frequency chip technology solutions form ams AG--AS3933,combine high-frequency technology solution from TI--CC2500 will be proper choice.It could match the design specifications of the system design requirements through debugging and testing.Besides in this thesis,based on the low-frequency wake-up technology and the TI's CC2500 chip,developed remote data reporting system so that the system can be awakened to upload data in real time.This system can be widely used in the area personnel location,material location and management and so on application.This system could achieve the desired functionality and low power requirements through the system design,antenna simulation,testing,and actual product application.
