Abstract

The present invention relates to an anti-theft device for luggage, which comprises a transmitting unit and a receiving unit, wherein the transmitting unit can transmit control signals, and the receiving unit comprises a corresponding control switch according to the control signals, a vibration sensor and an alarm circuit; the vibration sensor can sense whether the receiving unit generates vibration signals due to the vibration of external force, and the alarm circuit acts according to signals transmitted by the control switch or the vibration sensor. When the receiving unit can not receive the control signals transmitted by the transmitting unit, the vibration sensor and the alarm circuit are started to carry out vibration detection and alarm distribution. When in an emergency, the transmitting unit directly controls the action of the alarm circuit through the control switch.

Description

Theft-proof device for luggage

The present invention is relevant a kind of radio antitheft unit, utilizes the vibration-sensing element to carry out the radio luggage alarm of burglar detection in particular for a kind of cooperation.

How at present general known theft-proof device for luggage is made up of a transmitter and a siren, wherein transmitter is to be carried by the user, siren then is positioned in the luggage, it is provided with buzzer and control siren switch, when transmitter and siren distance to each other surpassed the original safe distance of setting, siren promptly made a sound and sounds the alarm.

But according to actual behaviour in service, sometimes the user is under the situation of safety and certainty, surpass safe distance and temporarily separate with its luggage, but forget and close siren earlier, for example handle when registration to restaurant's sales counter as the user, and temporarily luggage is kept somewhere by the sofa of hall, at this moment, known alarm makes the mistake action easily and pipes without restraint, makes the user awkward embarrassed!

In addition, because the control siren switch of known alarm is to be arranged on the siren,, stops buzzer to make a sound, and under the unwitting situation of user, set about to commit theft so make the burglar who has the knack of this device can directly close siren easily.

In view of this, creator of the present invention concentrates on studies, and does further improvement at the detecting mode and the control mode of at present general theft-proof device for luggage.

Thereby the object of the present invention is to provide a kind of the cooperation to implement the theft-proof device for luggage that malfunction is avoided in vibration detecting action.

Another object of the present invention is to provide a kind of can be by the theft-proof device for luggage of user's ACTIVE CONTROL alarm action at any time.

Theft-proof device for luggage of the present invention, it mainly is to comprise a transmitter unit and at least one receiving element, this transmitter unit and receiving element are to adopt the radio wave transfer mode and carry out the control of signal each other, and it is to be carried and be arranged at by the user on the antitheft luggage of desire respectively.

This transmitter unit is except should comprising interlock circuits such as basic radio transmission and signal coding, it should also include a control key groups, this control key groups can be made up of a plurality of button, each button all can produce different control signals, select according to need to launch the different receiving elements that controls signal to for the user, to carry out the execution of corresponding action.

These receiving elements are except should comprising interlock circuits such as basic radio reception and signal decoding, it also comprises a gauge tap, a Vibration Sensor and a circuit for alarming, gauge tap can be carried out corresponding action according to the control signal that transmits, but whether this receiving element of Vibration Sensor sensing influenced by external force vibration and produces vibration signal, circuit for alarming links the caution element, control signal that it can transmit according to gauge tap or Vibration Sensor or vibration signal and the signal that gives the alarm; Wherein warn element and can be buzzer or flasher or electric shock device.

When receiving element and transmitter unit each other in the distance range of setting (being the safe range that the user can take into account), the sense vibrations device is to be in closed condition, have only this moment and see through control key groups control gauge tap and could start circuit for alarming, so can effectively avoid malfunction.

And when receiving element and transmitter unit surpass the distance range of setting each other, (surpass safe range), the sense vibrations device will be unlocked and enter warning detecting state, this moment needs only receiving element or luggage is moved, when clashing into, all will start circuit for alarming at once, to reach antitheft effect.

In fact, except general basic start button and shutdown button, also can set up urgent button and stop key in the control key groups of transmitter unit.

Wherein, urgent button can be applicable to multiple emergency situations, and whether its using time is not restricted to the distance of transmitter unit and receiving element above the scope of setting.For example, in the numerous place of the crowd, when the user can't see luggage, this moment, no matter whether its both distance surpassed setting range, all can confirm luggage (property) position by pushing urgent button; Or when seeing that the someone attempts to steal luggage, no matter whether its both distance surpasses setting range, all can push urgent button immediately and frightens the usefulness of resistance as warning; Or when other emergencies, can have usefulness concurrently as individual's emergency.Stopping key then can be as the usefulness of cancelling, stop the circuit for alarming action.

Wherein the control key groups of this transmitter unit includes a start button and a shutdown button at least.

Wherein this start button is the design of adopting integral type with shutdown ammonium key:

Wherein the control key groups of this transmitter unit includes one and can stop to swear that telegraph circuit gives the alarm signal stops the ammonium key.

Wherein the control key groups of this transmitter unit includes one and can directly start the give the alarm urgent button of signal of circuit for alarming.

Wherein this Vibration Sensor is the angle variation of the white sensing receiving element of mat, and sends vibration signal.

Wherein this gauge tap is to be the open type change-over switch.

Wherein this caution element is meant a buzzer, and the alarm signal of the caution of sounding is provided.

For the effect that further specifies feature of the present invention and can reach, below in conjunction with accompanying drawing the present invention is done a detailed description, wherein:
