Abstract
The utility model relates to an automatic follow-up telephone antitheft alarming device which can produce alarming sound and remotely send alarming situation signal. The utility model utilizes the opposite magnetic poles of the magnet to control a contacting switch; the switch is connected with a turnoff dialing circuit through a lead; the turnoff dialing circuit is connected with a turnoff alarming circuit and is provided with a phone dialing outputting port; the turnoff alarming circuit is connected with a loudspeaker; the front end of the turnoff dialing circuit is connected in parallel with a remote control on-off switch. The user setup the work state of the alarming circuit through the remote control switch; the magnetic pole control switch cuts the alarming circuit when robber enters the security area and then the alarming device immediately produces alarming sound as well as calls the appointed phone and beep-pager so as to send the alarming situation.
Description
The utility model relate to a kind of with alert in time to the call of appointment, call and the device that gives the alarm at the scene.
At present, known burglar alarm structure is to be made of infrared induction probe (or contact-making switch), receiver, warning circuit, loudspeaker.In the time of in the robber enters the strick precaution zone, infrared probe is by the thermal source induction to human body, or in the robber enters the strick precaution zone, the contact-making switch automatic cutout, send alert by infrared induction probe or contact-making switch to receiver, receiver is to the loudspeaker signal that gives the alarm, and sound gives the alarm.But infrared induction probe is by the thermal source induction, can't distinguish human body and other animal, makes the mistake induction easily and sends false positive signal.And alerting signal can only be sent in taking precautions against the zone, can not in time send alerting signal at a distance.These hundreds of at least units of class alarm cost, units up to ten thousand at most can't popularize towards masses and use.
The purpose of this utility model is achieved in that and on the magnet break-make contact-making switch is being set in opposite directions, the switch ends lead links to each other with alarm, open circuit dial-up circuit and breaking alarming circuit and teleswitch are set in the alarm, when the magnet on-off switch disconnects, open circuit automatic dial-up circuit and breaking alarming circuit in the alarm enter duty immediately, by the dialing output port, send alert to telephone set, simultaneously alarm is by the loudspeaker sound that gives the alarm, and the scene of reaching gives the alarm and the remote purpose of transmitting alert.
Go up the art scheme owing to adopt, can send the alert signal exactly.Whole device only adopts the magnetic pole switch and the automatic dialing alarm circuit that opens circuit, and simple in structure, cost significantly reduces.
Below in conjunction with accompanying drawing and example the utility model is further specified.
Fig. 1 is circuit theory diagrams of the present utility model.
Fig. 2 is an instance graph of the present utility model.
Among the figure 1, magnet 2, magnet 3, switch 4, lead 5, teleswitch 6, the dial-up circuit 7 that opens circuit, dialing output port 8, breaking alarming circuit 9, loudspeaker 10, magnet mounting box 11, magnet mounting box 12, alarm box.
In Fig. 1, magnet 1, magnet 2 magnetic pole are in opposite directions arranged, switch 3 is fixedlyed connected with magnet 2, switch 3 is connected with the dial-up circuit 6 that opens circuit by lead 4 and is in parallel with teleswitch 5, the dial-up circuit 6 that opens circuit is provided with dialing output port 7, the dial-up circuit 6 that opens circuit is connected with breaking alarming circuit 8, and breaking alarming circuit 8 is connected with loudspeaker 9.
In Fig. 2, magnet 1 places in the magnet mounting box 10, be installed on the below N utmost point up, magnet 2S extremely goes up installation switch 3 contacts and places in the magnet mounting box 11, the N utmost point is installed on the top down, switch 3 two ends are by the lead 4 and dial-up circuit 6 polyphones that open circuit, and with shake control switch 5 and connecting, the dial-up circuit 6 that opens circuit is provided with dialing output port 7 and connects telephone set, breaking alarming circuit 8 connects loudspeaker 9 and is connected with the dial-up circuit 6 that opens circuit, and the dial-up circuit 6 that opens circuit, breaking alarming circuit 8, loudspeaker 9 are installed in the alarm box 12.
Below be the utility model application example:
The automatic tracking theft-proof alarm device of home telephone is in the household of automatic tracking theft-proof alarm device of having a telephone installed, because door closes, the magnetic pole switch is because the principle that magnetic pole repels mutually with the utmost point, switch closure under magneticaction, and warning system is that circuit is in path.After door is unlocked, magnet separates immediately, lose magneticaction, the switch contact disconnects switch because the magnet action of gravity is fallen immediately, whole warning circuit is in off state, alarm enters work, the sound that gives the alarm, fright robber, and send the alert signal to designated telephone number, called number by telephone set, allow the people who receives alert in time take treatment measures.The duty setting and the releasing of alarm for convenience, when passing in and out door, teleswitch is carried out the break-make setting with telepilot, the false alarm phenomenon that can get rid of normal opening and closing door, whole device only needs hundred yuan with interior cost cost, the purpose of taking precautions against interior warning in district and long-distance transmissions alert can be reached, the false alarm situation can be do not occurred.
