Abstract
The invention discloses a prompting device, particularly relates to a device for preventing a user from forgetting a key. The device is characterized in that a magnetic stripe is arranged on the key; a prompting device is arranged corresponding to the magnetic stripe; a sensor, a chip, a switch and a buzzer are arranged on the prompting device, and are in circuit connection. According to the device for preventing the user from forgetting the key, whether the key is kept with the user or not can be sensed and confirmed when the user opens a door to go out, and a prompt is given, so that the trouble caused by forgetting the key is avoided.
Description
Technical field
The present invention relates to alarm set, relate in particular to a kind of anti-key apparatus of leaving behind.
Background technology
People usually can forget and carry key when going out, and cannot enter undoubtedly after on door lock and can bring no small trouble, likely bring unforeseen consequence.Therefore be necessary to design a kind of device, before people go out, send the prompting of carrying keys.
Summary of the invention
In order to overcome people, forget and carry the trouble that key brings, the present invention aims to provide a kind of device that prevents from leaving behind key that has.
Of the present inventionly anti-leave behind key apparatus, there is following architectural feature:
Prevent leaving behind key apparatus, it is characterized in that: magnetic stripe is being set on the key, and corresponding magnetic stripe arranges an alarm set, inductor, chip, switch and hummer that circuit connects are set on described alarm set.
Described inductor and magnetic stripe are infrared induction.
Beneficial effect: carry key while reminding people to go out, avoided unnecessary trouble.
Accompanying drawing explanation
Fig. 1 is the anti-structural representation of leaving behind key apparatus of the embodiment of the present invention.
Embodiment
The description of symbols relating in accompanying drawing: chip 1, inductor 2, switch 3, hummer 4, key 5, magnetic stripe 6.
Anti-structure and the working method of leaving behind key apparatus that is embodiment to the present invention below in conjunction with accompanying drawing is elaborated.
As shown in Figure 1, prevent leaving behind key apparatus, comprise key 5 and reminiscences, described key 5 arranges magnetic stripe 6, and described reminiscences arranges chip 1, inductor 2, switch 3 and hummer 4.
Reminiscences is arranged on to the wall on a limit, when having people through reminiscences, inductor 2 can sense infrared ray, and can scan the magnetic stripe 6 of key 5, when not scanning, can transfer signals to chip 1, and chip 1 is controlled hummer 4 and sent prompting; When inductor 2 scans after the key 5 with magnetic stripe 6, chip 1 can be controlled hummer 4 and close.
When not needing reminiscences work, can close by switch 3.
The anti-key apparatus of leaving behind of the present invention, carries key while going out for prompting people, avoids unnecessary trouble to have positive effect.
Finally; be noted that above content is only in order to a kind of technical scheme of the present invention to be described, but not limiting the scope of the invention; the simple modification that those skilled in the art carries out technical scheme of the present invention or be equal to replacement, does not all depart from essence and the scope of technical solution of the present invention.
