摘 要
射频识别技术（Radio Frequency Identification，缩写RFID），射频识别技术是20世纪90年代开始兴起的一种自动识别技术，射频识别技术是一项利用射频信号通过空间耦合(交变磁场或电磁场)实现无接触信息传递并通过所传递的信息达到识别目的的技术。实际上是自动识别技术(AEI，Automatic Equipment Identification)在无线电技术方面的具体应用与发展。该项技术的基本思想是，通过采用一些先进的技术手段，实现人们对各类物体或设备 (人员、物品) 在不同状态(移动、静止或恶劣环境)下的自动识别和管理。
本文介绍了在家庭宠物管理方面，采用基于RFID技术的宠物自动喂食机，针对特定数据编码的标签，实现喂食器的自动感应动作，通过低功耗单片机MSP430对宠物喂食进行自动控制，携带在宠物上面的电子标签采用有源RFID-CC2500无线通讯模块，模块尽可能小，以便宠物携带，用纽扣电池，保证使用时间。
基于RFID技术的宠物自动喂食机的出现，方便了我们对宠物的家庭式的管理，为我们减轻了不少的麻烦，在解决能耗问题上也迈进了一步，它在今后的物流，养殖，工业领域中也将产生巨大的作用。

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.
