针对传统U盘存在容易丢失的问题,提出了一种基于蓝牙技术的智能防丢型U盘的设计方案。该方案将蓝牙技术用于U盘,使U盘具备了特点,实现了与手机绑定防丢失功能。该基于蓝牙技术的智能防丢型U盘由蓝牙模块、主控芯片和储存器构成。其中,蓝牙模块用于和手机蓝牙绑定,主控制芯片负责闪存与USB连接,储存器用于数据的存储。当手机与U盘相距距离过长(一般为10m以外),手机接收不到U盘的蓝牙信号时,触发手机客户端上的报警系统。%The existing problemoftraditional U disk is easy to lose.This paper presents a novel anti-lostU disk with Bluetooth. We transmit the technology of bluetooth into U diskto make itbinding to the phone.Itconsists ofBluetoothchip ,the main control chipand lfash memory chip.When the phone from the U disk over a certain distance(over 10m generally),thephone alarms.
