微功耗主動式RFID系統(tǒng)的標簽一般采用紐扣電池供電，其功耗是一個很關(guān)鍵的問題，
目前常采用定時喚醒的工作方式，本文介紹了低頻喚醒技術(shù)的實現(xiàn)原理，并討論了將其應(yīng)用到微功耗主動式RFID系統(tǒng)中解決射頻標簽內(nèi)發(fā)射模塊的功耗問題，給出了低頻喚醒的關(guān)鍵電路和程序流程，實踐證明該方案可以很好地解決主動式RFID的功耗問題。
關(guān)鍵詞:低頻喚醒；主動式RFID；標簽；微功耗
THE RESEARCH AND APPLICATION OF MICOR-POWER ACTIVE RFID BASED ON LF WAKE-UPTECHNOLOGY Cao Shihua1 Zhaofang2 (1.HangZhou Normal University, 2.Beijing University of Posts and Telecommunications ) Abstract: Tags of micro-power active RFID system are usually supllied by cells , the power consumption is a crucial factor. The currently applied operating mode is of timing wake-up. In this paper, presented the method of LF wake-up technology , discussed how to use it to solve the low-power problem of active RFID tag. Put forward the crucial electrocircuit and working program flow. Practices show that this solution is capable of solving the problem of low-power of active RFID.
