Abstract
The present invention relates to a kind of USB flash disk.A kind of USB flash disk with prompting function, including shell and movement, in addition to：LED warning lamps, are arranged on shell；Monitoring unit is read and write, is connected with movement and monitors the read and write operation of USB flash disk；Clock unit, receive the control signal of read-write monitoring unit, for read-write monitoring unit when monitoring USB flash disk without read or write, clock unit carries out timing, and when monitoring USB flash disk just in read or write, clock unit does not work read-write monitoring unit；Control unit, it is connected with clock unit, when the timing of clock unit reaches preset time, control LED warning lamps light.The USB flash disk that the present invention is solved after use is easily lost this problem, serves the reminding effect to user, and manufacturing cost is low, and prompting function is notable.
Description
【Technical field】
The present invention relates to a kind of USB flash disk.
【Background technology】
USB flash disk is quite varied as a kind of movable storage device easy to carry, easy to use, application.But USB flash disk this body
Product is compact, is not easy to discover, and people it is easy to forget that USB flash disk is pulled out from electronic equipment, in turn result in USB flash disk after using complete USB flash disk
Loss.Instantly, for the problem, it is proposed that the improvement project of some USB flash disks, but also there is be fabricated in itself for these schemes
This height, prompting function are bad, waste the problems such as electric energy.
【The content of the invention】
To solve the above problems, the present invention proposes a kind of USB flash disk for having prompting function, preventing loss.Concrete technical scheme is as follows：
A kind of USB flash disk with prompting function, including shell and movement, in addition to：LED warning lamps, are arranged on shell；Read-write prison
Unit is surveyed, is connected with movement and monitors the read and write operation of USB flash disk；Clock unit, receive the control signal of read-write monitoring unit,
Monitoring unit is read and write when monitoring USB flash disk without read or write, clock unit carries out timing, and read-write monitoring unit is monitoring U
Just in read or write, clock unit does not work disk；Control unit, it is connected with clock unit, in the timing of clock unit
When reaching preset time, control LED warning lamps light.
Preferably, described preset time is more than or equal to 5 minutes.
Preferably, the LED warning lamps are red LED lamp.
Further, described control unit control LED warning lamps are lighted with certain frequency flicker.
Preferably, the reset switch being connected with clock unit, the control of described reset switch are additionally provided with the shell
The timing of clock unit resets.
Pass through above-mentioned technical proposal, the USB flash disk that the present invention solves after use are easily lost this problem, served to user
Reminding effect, and manufacturing cost is low, and prompting function is notable.
【Brief description of the drawings】
Fig. 1 is the module connection figure of the present invention；
Fig. 2 is the structural representation of the present invention.
【Embodiment】
As shown in figure 1, read-write monitoring unit is connected with USB flash disk movement, USB flash disk is in read or write, interior data memory
Magnitude of voltage can change, read-write monitoring unit be used for monitor this magnitude of voltage, when USB flash disk is without read or write and USB flash disk reading or
Respectively and two kinds of control signals are sent during write operation to clock unit.Clock unit responds both control signals, USB flash disk without
Timing is proceeded by during read or write, clock unit resets and is stopped USB flash disk just in read or write.With clock unit
The control unit of connection monitors the timing of clock unit in real time, when the timing of clock unit reaches the internal preset time, control
Unit control LED warning lamps light.So, after one end time of USB flash disk is not used in user, LED warning lamps will light, and carry
Awake user pulls out USB flash disk.Preset time was set greater than or equal to 5 minute, preferably 5 minutes, in general, if used
Person is not written and read use still after 5 minutes to USB flash disk, may be regarded as user and does not use USB flash disk.
As shown in Fig. 2 LED warning lamps 11 are arranged on shell 1, and LED warning lamps 11 use the red-light LED of high brightness
Lamp, and control unit control LED warning lamps 11 are lighted with certain eye-catching frequency scintillation, so, user is more prone to find
The USB flash disk not pulled out, its prompting function are more notable.
The reset switch 12 being connected with clock unit is additionally provided with the shell 1, when described reset switch 12 controls
The timing of clock unit resets.User presses reset switch 12 after USB flash disk is found, clock unit is that timing resets, from zero again
Timing, LED warning lamps 11 just no longer light, and reduce the waste of electric energy.
