Embodiment
[0028] The anti-lost U disk based on bluetooth technology described in the embodiment of the present invention, such as figure 1 As shown, it includes the U disk body, and also includes a main control chip, an alarm prompt module and a power supply module. terminal connection, the main control chip is connected with a bluetooth module;
[0029] The power module is used to supply power to the main control chip;
[0030] The main control chip is used to continuously scan whether there is broadcast packet data corresponding to the U disk through the bluetooth module, and when the corresponding broadcast packet data is scanned, an alarm prompt signal is sent to the alarm prompt module;
[0031] The alarm prompt module is configured to issue an alarm prompt after receiving an alarm prompt signal.
[0032] The actual use process is as figure 2 As shown, first of all, the broadcast package data of its unique information sequence can be pasted on the U disk in the form of a two-di...

The invention relates to a USB flash disk. The invention aims to solve the problem that the USB flash disk is difficult to find after being lost in the prior art. The anti-lost USB flash disk comprises a USB flash disk body, a main control chip, an alarm prompt module and a power supply module, the power supply module is connected with the main control chip, the alarm prompt module is connected with the main control chip, and the main control chip is connected with the Bluetooth module; the main control chip is used for continuously scanning whether broadcast packet data corresponding to the USB flash disk exists or not through the Bluetooth module, and sending an alarm prompt signal to the alarm prompt module after the corresponding broadcast packet data is scanned; and the alarm prompt module is used for sending an alarm prompt after receiving the alarm prompt signal. According to the invention, a user can conveniently find the USB flash disk in a short time without influencing the normal use of the USB flash disk, and even if the USB flash disk and the user terminal are in a non-connection state, the alarm prompt of the USB flash disk can also be realized.
Description
technical field [0001] The invention relates to a U disk, in particular to a bluetooth technology-based anti-loss U disk, a user terminal and a method for preventing loss of the U disk. Background technique [0002] In daily life and work, U disks are widely used and are often used to store some more important data. Due to their small size, U disks are not easy to attract attention, are easily lost or forgotten by users, and are difficult to retrieve. come loss. At present, most of the anti-lost devices on the market use GPS positioning, but in this way, this positioning function will not be available when the U disk is in a place with weak GPS signals such as the basement. [0003] In the prior art, there is also a Bluetooth module installed in the U disk and connected to the user terminal through the Bluetooth module. When the user terminal detects that the communication is disconnected, the user terminal sends an alarm prompt, which greatly limits the U disk. The usage ...
