摘  要
 在繁忙的都市生活中，人们的生活节奏越来越快，由于工作和竞争的压力，一些人疲于奔命，在快节奏的都市生活中总是有人常常会记不清钱包放在哪里，或者把手机弄丢了，更有甚者是带孩子上街玩，一转眼把孩子弄丢了。
 本文介绍了在防盗管理方面，采用无线射频技术的防丢器，针对特定数据编码的标签，实现防丢器的自动感应动作。此次设计采用低功耗单片机MSP430F2011对物品防丢进行自动控制。利用RFID-CC2500无线通讯模块进行信号的发送与接收，外形设计要尽可能的小，便于携带。同时采用纽扣电池，保持长时间供电。
 基于RFID技术的防丢器的出现，方便了我们对身边物品的管理，为我们减轻了不少的麻烦，同时在解决能耗问题上也迈进了一步，它在今后的物流、交通管理和工业领域中也将产生巨大的作用。

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.
