摘  要
 在繁忙的都市生活中，人們的生活節奏越來越快，由于工作和競爭的壓力，一些人疲于奔命，在快節奏的都市生活中總是有人常常會記不清錢包放在哪里，或者把手機弄丟了，更有甚者是帶孩子上街玩，一轉眼把孩子弄丟了。
 本文介紹了在防盜管理方面，采用無線射頻技術的防丟器，針對特定數據編碼的標簽，實現防丟器的自動感應動作。此次設計采用低功耗單片機MSP430F2011對物品防丟進行自動控制。利用RFID-CC2500無線通訊模塊進行信號的發送與接收，外形設計要盡可能的小，便于攜帶。同時采用紐扣電池，保持長時間供電。
 基于RFID技術的防丟器的出現，方便了我們對身邊物品的管理，為我們減輕了不少的麻煩，同時在解決能耗問題上也邁進了一步，它在今后的物流、交通管理和工業領域中也將產生巨大的作用。

關鍵詞：RFID；防丟器；CC2500；單片機。

Abstract
In busy city life, people's rhythm of life is getting quickly. As a result of the work and the competition pressure, some people are tired out from the press. Some people will always record the unclear wallet where in the quick rhythm's city life. Some has lost the handset, and what is more ,who leads the child to take to the streets to play, then the child lost.
This article introduces in the security management aspect. Uses against loses based on the RFID technology, in view of the specific data codling’s label, realizes against loses the auto-induction movement. This design uses low power MCU MSP430F2011 against to lose to the goods carries on the automatic control. Using RFID-CC2500 wireless communication module clear signal transmission and receive. The contour design must small as far as possible, to be advantageous carries. Simultaneously uses the button battery maintains the long time power supply.
Against loses the appearance based on the RFID technology, has facilitated us to the side goods management, reduced many troubles for us. In solved in the energy consumption problem also to make great strides forward one step, it in present's physical distribution, in the traffic control and the industrial field will also have the huge function.
