射頻識別技術(Radio Frequency Identification,縮寫RFID),射頻識別技術是20世紀90年代開始興起的一種自動識別技術,射頻識別技術是一項利用射頻信號通過空間耦合(交變磁場或電磁場)實現無接觸信息傳遞并通過所傳遞的信息達到識別目的的技術。實際上是自動識別技術(AEI,Automatic Equipment Identification)在無線電技術方面的具體應用與發展。該項技術的基本思想是,通過采用一些先進的技術手段,實現人們對各類物體或設備 (人員、物品) 在不同狀態(移動、靜止或惡劣環境)下的自動識別和管理。
本文介紹了在家庭寵物管理方面,采用基于RFID技術的寵物自動喂食機,針對特定數據編碼的標簽,實現喂食器的自動感應動作,通過低功耗單片機MSP430對寵物喂食進行自動控制,攜帶在寵物上面的電子標簽采用有源RFID-CC2500無線通訊模塊,模塊盡可能小,以便寵物攜帶,用紐扣電池,保證使用時間。
基于RFID技術的寵物自動喂食機的出現,方便了我們對寵物的家庭式的管理,為我們減輕了不少的麻煩,在解決能耗問題上也邁進了一步,它在今后的物流,養殖,工業領域中也將產生巨大的作用。

Abstract
RFID (Radio Frequency Identification, abbreviation RFID), radio frequency identification technology has grown upthe beginning of the 20th century, which is an automatic identification technology in the rise of the 90's.Radio frequency identification technology is a radio frequency signal through the use of coupled space (alternating magnetic field or electromagnetic field) to achieve non - contact with the transmission of information,which is also through the transmission of information technology to achieve identification purposes. In fact, applying radio frequency identification is the specific application and development of automatic identification technology (AEI, Automatic Equipment Identification) in radio technology. The basic idea, is that ,through some advanced technological means ,it brings about various types of objects or equipment (personnel, materials) in different states (mobile, stationary or harsh environment) ,to achieve the automatic identification and management.
This paper describes that RFID technology-based automatic pet feeding machine and code-specific data label is used in the family pet management.It could achieve the induction of the automatic feeder. The MSP430 low-power single-chip microcomputer is to achieve automatic feeding pets. The active RFID of pets adopts RFID-CC2500 wireless communication module. The module is should be as small as possible in order to keep pets conveniently.Using a button battery to ensure the time of using.
The appearence of RFID technology-based pet automatic feeding machine, makes conveniently for our family pet management,reduces a lot of trouble for us.It will make a great progress in solving the issue of enegry consumption .It will also play a significant role in logistics, cultivation, industry in the future.
