Abstract
The invention provides a low-power anti-loss safety U-disk. The low-power anti-loss safety U-disk comprises a USB interface, a USB switch, a memory, a controller, a power module and a communication module, and also a U-port status detection module; the USB interface is connected with the communication module by use of a U-port status detection module; when the U-port status detection module detects that the USB interface is not connected to the USB socket of an external reading device, the communication module is in regular communication with a hand-held device in a first mode; when the U-port status detection module detects that the USB interface is connected to the USB socket of the external reading device, the communication module is in regular communication with the hand-held device in a second mode; the power consumption in the first mode is lower than the power consumption of the second mode. According to the low-power anti-loss safety U-disk, the U-port status detection module is arranged between the USB interface and the communication module; according to the status of the U-port, the communication module is switched between the first mode and the second mode to work, and therefore, the power consumption of the U-disk is remarkably reduced and the practicability of the U-disk is enhanced.
Description
technical field [0001] The invention relates to a USB flash drive, in particular to a low power consumption anti-lost safe USB flash drive. Background technique [0002] As a modern information storage device, the USB flash drive is a portable office tool for many people. It is favored by people for its small size, large storage capacity, and easy portability. But at the same time, because of its small size, many users forget to take their USB flash drive into the USB socket of the computer, which is very easy to lose and forget. [0003] Chinese patent CN103824581A discloses a safe and confidential USB flash drive, including a casing, one end of the casing is open, a circuit board and a rechargeable battery are arranged inside the casing, an antenna, a wireless bluetooth control single-chip microcomputer, LED lights, buttons, Buzzer, charging circuit, large-capacity memory, USB switch, USB interface seat and U disk interface, antenna, LED lights, buttons, buzzer, USB switc...
