Abstract
The present invention discloses an alarm with a magnetic recognition device. The alarm with the magnetic recognition device comprises ferromagnetic substance, an induction coil, a recognition unit, an oscillation alarm unit, a sound-light alarm unit and a timer. The alarm provided by the invention is characterized in that: the induction coil is connected with the recognition unit, the recognition unit is electrically connected with the sound-light alarm unit through the oscillation alarm unit, the timer is electrically connected with the oscillation alarm unit, and the ferromagnetic substance is a key or a mobile phone. The alarm with a magnetic recognition device is simple in manufacture, low in cost and easy to operate, and is beneficial to popularization and application.
Description
Technical field
The present invention relates to a kind of band to be magnetic the alarm of recognition device.
Background technology
Alarm has a variety of, as door and window alarm, vibrations alarm, Infrared intrusion detector etc., but in daily life as key, file etc. are placed sometimes conveniently, often needs when deployed to find for a long time.
Summary of the invention
For solving above-mentioned existing shortcoming, fundamental purpose of the present invention is to provide a kind of band of practicality to be magnetic the alarm of recognition device, makes simple, easy to use, with low cost, is conducive to applying.。
For reaching above-described object, following technical scheme taked by the be magnetic alarm of recognition device of a kind of band of the present invention:
A kind of band is magnetic the alarm of recognition device, comprise ferromagnetic material, inductive coil, recognition unit, vibration alarm unit, acousto-optic warning unit and timer, it is characterized in that, described inductive coil is connected with described recognition unit, described recognition unit is electrically connected with described acousto-optic warning unit by described vibration alarm unit, described timer is electrically connected with described vibration alarm unit, and described ferromagnetic material is key or mobile phone.
Adopt the present invention of as above technical scheme, there is following beneficial effect:
Because ferromagnetic material is close to acousto-optic warning unit work during inductive coil, this position placed safely by these articles for use of prompting user, and this device makes simple, easy to use, with low cost, is conducive to applying.
Accompanying drawing explanation
Fig. 1 is circuit block diagram of the present invention.
Embodiment
In order to further illustrate the present invention, be described further below in conjunction with accompanying drawing:
As shown in Figure 1, the be magnetic alarm of recognition device of a kind of band of the present invention comprises ferromagnetic material, inductive coil, recognition unit, vibration alarm unit, acousto-optic warning unit and timer; Described ferromagnetic material is key or mobile phone; Described inductive coil is connected with recognition unit, and described recognition unit is electrically connected with acousto-optic warning unit by vibration alarm unit, and described timer is electrically connected with vibration alarm unit.Its principle of work is: when there being ferromagnetic material close to inductive coil, recognition unit receives induced signal, inputs to vibration alarm unit, and vibration alarm unit drives acousto-optic warning unit work, and this position placed safely by these articles for use of prompting user.
