Abstract
The utility model relates to an alarm system, in particular to an alarm system of an anti-theft lost-preventing USB flash disk. The USB flash disk comprise a host computer and a cover, wherein the host computer is provided with a signal emitting device, a host computer battery and a host computer position switch, and the cover is provided with a cover position switch, a signal receiving device, a signal converting device, an electromagnetic relay, a lithium battery, an alarm and an indicator lamp. When the cover position switch and the host computer position switch are both closed when sensing that the cover is separated from the host computer, a loop of the host computer battery and the signal emitting device on the host computer is powered on, the signal emitting device emits signals, the signal receiving device receives the signals, and the signals are converted into electric signals through the signal converting device and transmitted to the electromagnetic relay. After the alarm system is powered on, a contact switch of the alarm system is turned off, and the alarm and the indicator lamp do not work. When the signal receiving device receives no signal, the electromagnetic relay is powered off, the contact switch of the alarm system is powered on, the alarm and the indicator lamp are both powered on through the contact switch and the cover position switch, and a user is reminded to know that the host computer is not located on the cover and look for the host computer as soon as possible.
Description
Technical field
The utility model belongs to technical field of electronic products, is specifically related to a kind of warning system of anti-theft and anti-losing USB flash disk.
Background technology
Widely used USB flash disk, comprise main frame and lid in the market.For preventing loss by the hook on lid and the connections such as key chain, lanyard, but exist main frame to separate with lid, lose critical piece and data, damnous situation.Separately have lid is connected with the parts of chain subclass with main frame, the chain fracture still likely occurs and cause the situation of losing main frame.
The utility model content
The above-mentioned defect existed in order to overcome the prior art field, the purpose of this utility model is, a kind of warning system of anti-theft and anti-losing USB flash disk is provided, and solves the problem that the computer USB mouth is easily lost or dropped on to the USB flash disk main frame.
The warning system of the anti-theft and anti-losing USB flash disk that the utility model provides, described USB flash disk comprises main frame and lid, also comprise the position of host machine switch, sender unit, cell host, signal receiving device, chromacoder, electromagnetic relay, the position of cap switch, pilot lamp, alarm and lithium battery, the position of host machine switch, sender unit and cell host are arranged in main frame, cell host is connected to the two ends of sender unit by the position of host machine switch, the position of cap switch, signal receiving device, chromacoder, electromagnetic relay, pilot lamp, alarm and lithium battery are arranged in lid, signal receiving device, chromacoder is connected successively with electromagnetic relay, pilot lamp and alarm are connected to respectively the two ends of lithium battery by the contact switch of position of cap switch and electromagnetic relay.
The warning system of the anti-theft and anti-losing USB flash disk that the utility model provides, cell host is micro battery.
The warning system of the anti-theft and anti-losing USB flash disk that the utility model provides, its beneficial effect is, monitors the USB flash disk state, points out the USB flash disk main frame away from lid, anti-theft and anti-losing is easy to use.
The accompanying drawing explanation
Fig. 1 is the utility model circuit theory diagrams.
Embodiment
With reference to the accompanying drawings, in conjunction with an embodiment, the warning system of a kind of anti-theft and anti-losing USB flash disk that the utility model is provided is described in detail.
With reference to Fig. 1, the warning system of a kind of anti-theft and anti-losing USB flash disk of the present embodiment, described USB flash disk comprises main frame and lid, also comprise the position of host machine switch, sender unit, micro battery, signal receiving device, chromacoder, electromagnetic relay, the position of cap switch, pilot lamp, alarm and lithium battery, the position of host machine switch, sender unit and micro battery are arranged in main frame, micro battery is connected to the two ends of sender unit by the position of host machine switch, the position of cap switch, signal receiving device, chromacoder, electromagnetic relay, pilot lamp, alarm and lithium battery are arranged in lid, signal receiving device, chromacoder is connected successively with electromagnetic relay, pilot lamp and alarm are connected to respectively the two ends of lithium battery by the contact switch of position of cap switch and electromagnetic relay.
When using USB flash disk, lid is separated with main frame, position of cap switch and position of host machine switch are all connected, micro battery on main frame and the loop of sender unit are switched on, sender unit sends signal to signal receiving device, signal receiving device sends signal to chromacoder again, chromacoder is converted to electric signal by signal and exports to electromagnetic relay, electromagnetic relay is connected, its normally closed contact switch J disconnects, the loop of alarm and pilot lamp and lithium battery disconnects, and alarm and pilot lamp are failure to actuate.When main frame away from lid, signal receiving device can't be received the signal that sender unit sends, the circuit of electromagnetic relay disconnects, its normally closed contact switch J closure, connect the loop of pilot lamp and alarm and lithium battery, pilot lamp is bright, and alarm gives the alarm, the prompting main frame, not in safe range, is recovered as early as possible.
The warning system of a kind of anti-theft and anti-losing USB flash disk of the present embodiment, micro battery is connected with main frame, when connecting the USB mouth of computer, main frame charged, power saving, energy-conservation.
