The wireless transmitting module comprises a sensor, a microcontroller and a wireless transmitter, an output end of the sensor is electrically connected with an input end of the microcontroller, and an output end of the microcontroller is electrically connected with an input end of the wireless transmitting module. The wireless receiving device comprises a wireless receiver, a microprocessor, a sound alarm device and a battery, an output end of the wireless receiver is electrically connected with an input end of the microprocessor, an output end of the microprocessor is electrically connected with an input end of the sound alarm device, an output end of the battery is electrically connected with an input end of the microprocessor, and the wireless transmitting module is connected with the wireless receiving device through a wireless signal. The wireless transmitting module is arranged on the USB flash disk, when the sensor senses the distance or pressure between the wireless receiving device and the USB flash disk exceeds set value, the wireless alarm device can send an alarm to prompt a user to take off the USB flash disk in time.
Description
Technical field
The present invention is a kind of wireless alarmer of USB flash disk specifically, belongs to wireless technical field.
Background technology
After a lot of people use USB flash disk in public, be easy to forget and take away, thereby cause USB flash disk to be lost that capsule information are lost, and cause heavy losses.In order to address the above problem, generally can be provided with warning device at USB flash disk, sound the alarm at set intervals, reminding user does not leave behind USB flash disk, but this warning device only is installed in USB flash disk itself, in noisy environment, be difficult to hear alarm sound, report to the police because alarm sound is time segment, when the user leaves just, the USB flash disk warning device is in sleep devices, still can't play the effect that reminding user is taken away USB flash disk.
Summary of the invention
The wireless alarmer that the purpose of this invention is to provide a kind of USB flash disk can be carried, and in time reminding user is not forgotten USB flash disk, thereby avoids bringing unnecessary trouble and loss to the user.
For achieving the above object, the technical solution used in the present invention is: the wireless alarmer of this USB flash disk, comprise the wireless transmitter module that is installed on the USB flash disk, and the radio receiver corresponding with wireless transmitter module, described wireless transmitter module comprises sensor, microcontroller and wireless launcher, the sensor output terminal is electrically connected with the microcontroller input end, and its input end of microcontroller output terminal and wireless transmit is electrically connected; Described radio receiver, comprise wireless receiver, microprocessor, audible alarm unit, battery, the wireless receiver output terminal is electrically connected with the microprocessor input end, output end of microprocessor is electrically connected with the audible alarm unit input end, the battery output terminal is electrically connected with the microprocessor input end, and wireless transmitter module is connected with radio receiver by wireless signal;
As preferably, sensor is range sensor or pressure transducer;
As preferably, battery is button cell;
As preferably, audible alarm unit is hummer or music player;
As preferably, stating microcontroller and microprocessor is the 89C51 single-chip microcomputer.
The invention has the beneficial effects as follows: be provided with wireless transmitter module at USB flash disk, with the radio receiver of USB flash disk with at one's side, when sensor sensing exceeds setpoint distance to the distance of radio receiver and USB flash disk, or pressure exceeds set pressure, will send alarm sound, thereby in time reminding user is taken away the USB flash disk of forgeing.
Description of drawings
Fig. 1 is the present invention's electricity theory diagram.
Embodiment
The present invention will be described below in conjunction with drawings and Examples.
As shown in Figure 1, the wireless alarmer of this USB flash disk, comprise the wireless transmitter module that is installed on the USB flash disk, and the radio receiver corresponding with wireless transmitter module, described wireless transmitter module comprises sensor, microcontroller and wireless launcher, the sensor output terminal is electrically connected with the microcontroller input end, and its input end of microcontroller output terminal and wireless transmit is electrically connected; Described radio receiver, comprise wireless receiver, microprocessor, audible alarm unit, battery, the wireless receiver output terminal is electrically connected with the microprocessor input end, output end of microprocessor is electrically connected with the audible alarm unit input end, the battery output terminal is electrically connected with the microprocessor input end, and wireless transmitter module is connected with radio receiver by wireless signal.
Described sensor is range sensor or pressure transducer.
Described battery is button cell.
Described audible alarm unit is hummer or music player.
Described microcontroller and microprocessor are the 89C51 single-chip microcomputer.
The first embodiment: sensor is range sensor, and audible alarm unit is hummer.
When the user inserts USB flash disk in the USB interface of computer, power connection, wireless module starts, the distance of range sensor Real-Time Monitoring USB flash disk and radio receiver, when the two distance exceeds setting range, range sensor sends the signal that senses to microcontroller, microcontroller is through after processing and analyzing, send wireless launcher to, wireless launcher is sent to wireless receiver by wireless signal, and wireless receiver goes out to deliver to microprocessor with the signal that receives, after microprocessor is analyzed and processed signal, start hummer, in time carry USB flash disk with reminding user.
The second embodiment: sensor is pressure transducer, and audible alarm unit is music player.
When the user inserts USB flash disk in the USB interface of computer, power connection, wireless module starts, the pressure that pressure transducer Real-Time Monitoring USB flash disk is subject to, if pressure transducer induction in each ten minutes is less than the existence of pressure, will with without the pressure signal transmission to microcontroller, microcontroller is through after processing and analyzing, send wireless launcher to, wireless launcher is sent to wireless receiver by wireless signal, and wireless receiver goes out to deliver to microprocessor with the signal that receives, after microprocessor is analyzed and processed signal, start music player, in time carry USB flash disk with reminding user.
