Abstract

The utility model relates to an intelligent anti-theft alarm which can identify masters and thieves. The utility model is characterized in that an identifying sensor is arranged in a double-bolt door lock; displacement sensors are arranged at a door and a door frame, and are electrically connected with an electronic sound circuit after connection in series. The identifying sensor controlled by a key can realize that when the masters enter the door the alarm doesn't sound, while when the thieves break into the door the alarm can sound for alarm. Thus the property of the masters can be effectively protected from loss.

Description

Can discern owner and thief's intelligent anti-theft alarm

The utility model belongs to the mechano-electronic class.Be specifically related to a kind of intelligent anti-theft alarm that can discern owner and thief.

Alarm kind on the market is a lot, but can not discern owner and thief.Therefore, all there is a thief to come warning, owner to come the drawback that equally also will report to the police.And, any place, always owner's is many, and what the thief came lacks.So above-mentioned alarm, the time has been grown, and will produce the effect of " wolf has come, and wolf has come " unavoidably.In the course of time, people do not want to take the trouble, and the possibility of abandoning using is just arranged, and what do not have alarm should have effect.Because of the alarm stolen incident that causes that can not normally play a role happens occasionally.

The purpose of this utility model, exactly for the user provides a kind of intelligent anti-theft alarm that can discern owner and thief, so that under normal circumstances alarm is not worked, when the thief commits theft, alarm sound your writing, that really plays alarm should have effect.Do following narration in conjunction with the accompanying drawings:

Accompanying drawing is the structural representation that can discern owner and thief's intelligent anti-theft alarm.

A kind of intelligent anti-theft alarm that can discern owner and thief, it is characterized in that: the inside of two flapper locks [7] is equipped with identification sensor [1], on door [12] and the doorframe [11] displacement transducer [2] is installed, identification sensor [1] and displacement transducer [2] series connection back ring circuit [14] with the electronics news and are electrically connected.Shown in the drawings is the intelligent anti-theft alarm that can discern owner and thief, and its identification sensor [1] and displacement transducer [2] are an embodiment who adopts the sensor that permanent magnet and tongue tube form.Identification sensor and displacement transducer can also be photoelectric sensor, proximity transducer.Its electronics news are rung circuit, an embodiment when being onsite alarming.During long-distance alarm, can also be the electronics emission, accept assembly.

The said intelligent anti-theft alarm that can discern owner and thief, it is characterized in that: identification sensor [1] is by often opening tongue tube [4] and permanent magnet [3] is formed, permanent magnet [3] is fixed on the middle part downside of the insurance dead bolt [9] in two flappers locks [7], often opens tongue tube [4] and is fixed near two flappers in left side, permanent magnet [3] position and locks on the outer casing inner wall of [7].

The said intelligent anti-theft alarm that can discern owner and thief, it is characterized in that: displacement transducer [2] is made up of normally closed tongue tube [5] and permanent magnet [6], permanent magnet [6] is fixed on the doorframe [11], and normally closed tongue tube [5] is fixed on door [12] position near permanent magnet [6] one sides.

Because the design feature of two flapper locks [7], owner gos out, and generally all will door be locked with key.Promptly stir lock core sliding piece [13] with key, lock core sliding piece [13] is stirred insurance dead bolt [9] again and is moved to the left, and the permanent magnet that is fixed in the above [1] also is moved to the left, and makes often to open tongue tube [4] closure under the action of a magnetic field, is ready.And door [12] in the case, must be in closed condition, and the normally closed tongue tube [5] of its displacement transducer [2] under the action of a magnetic field of permanent magnet [6], is off-state, and alarm stands alert.

When owner returns, turn the key in the lock, at first stir lock core sliding piece [13], lock core sliding piece [13] is stirred insurance dead bolt [9] again and is moved right, the permanent magnet that is fixed in the above [1] also moves right, and often opens tongue tube [4] under the situation of no the action of a magnetic field power, recovers normally open.Enter [12] although owner's this moment will push the door open, be fixed on the normally closed tongue tube [5] on the door [12], recovering normally off away from permanent magnet [6] back, still, be connected on the tongue tube [4] of often opening that triggers in the loop and be off-state, alarm can not send warning.

When the thief commits theft,, can only force open the door because the thief does not have key and opens the door.And the tongue tube [4] of often opening of this moment is closure state.When door [12] was outwarded winding certain angle, normally closed tongue tube [5] after losing the action of a magnetic field, recovered closure state, triggers the loop and connects, and alarm sends warning.

Can discern the invention and the enforcement of owner and thief's intelligent anti-theft alarm, can monitor the monitored site long-term effectively, social incidence of cases is not suffered a loss, reduced to protection people property positive effect.

Claims

1. the intelligent anti-theft alarm that can discern owner and thief, it is characterized in that: the inside of two flapper locks [7] is equipped with identification sensor [1], on door [12] and the doorframe [11] displacement transducer [2] is installed, identification sensor [1] and displacement transducer [2] series connection back ring circuit [14] with the electronics news and are electrically connected;

2. according to the said intelligent anti-theft alarm that can discern owner and thief of claim 1, it is characterized in that: identification sensor [1] is by often opening tongue tube [4] and permanent magnet [3] is formed, permanent magnet [3] is fixed on the middle part downside of the insurance dead bolt [9] in two flappers locks [7], often opens tongue tube [4] and is fixed near two flappers in left side, permanent magnet [3] position and locks on the outer casing inner wall of [7];

3. according to the said intelligent anti-theft alarm that can discern owner and thief of claim 1, it is characterized in that: displacement transducer [2] is made up of normally closed tongue tube [5] and permanent magnet [6], permanent magnet [6] is fixed on the doorframe [11], and normally closed tongue tube [5] is fixed on door [12] position near permanent magnet [6] one sides.
