Description

Only institute villa protection alarm device

Technical field

The utility model relates to a kind of only institute villa protection alarm device, and this warning device produces detectable signal by the condenser type human inductor, and when the approaching detection of human body line, single-chip microcomputer gets final product output alarm signal.

Background technology

Chinese patent 92239284.6 discloses a kind of antitheft door wire break alarm device, and a transistor switching circuit is arranged, and the output terminal of this circuit is connected to warning circuit normally open contact and described alarm bell.The input end of this circuit is connected to warning network.This warning network is thin plain conductor, be embedded in Men Tizhong through back-shaped coiling, relay coil of its transistor collector end serial connection in the described on-off circuit, a collector terminal self-sustaining normally open contact in parallel with emitter terminal, compared with the prior art this warning device has and prevents robber's tool using force open the door, punch crime, the automatic advantage of record crime clue.But this patent could be reported to the police after need destroying plain conductor, and needs to recover again the netting twine of reporting to the police after destroying, and is unfavorable for implementing, and also can't monitor some only institutes or bigger villa.Therefore, need to propose a kind of new only institute villa protection alarm device.

Summary of the invention

The purpose of this utility model is to provide a kind of only institute villa protection alarm device, this warning device is made of condenser type human inductor, central controller, alarm circuit, phone transmission circuit, when the approaching detection of human body line, central controller can be judged messenger's attribute, notify owner immediately, and report to the police by wired or wireless telephone network.

The purpose of this utility model is realized by following technical proposals: a kind of only institute villa protection alarm device, form by condenser type human inductor, central controller, alarm circuit, imaging circuit, phone transmission circuit and the software that is complementary, its main points are: described human inductor is made up of two open detection lines, signal generating circuit and RC oscillating circuits, and described human inductor output terminal is electrically connected with the RA0 end of central controller; Described alarm circuit is electrically connected with RA4, the RB0 end of central controller; Described imaging circuit is electrically connected with RB1, RB2, RB3, the RB4 end of central controller; Described phone transmission circuit is electrically connected with RB5, RB6, the RB7 end of central controller.

Compared with the prior art the utility model has following advantage:

1, because the utility model adopts the condenser type human inductor as detecting element only institute or villa to be monitored, can early detection and judge merit, be beneficial to and in time take measures to reduce the loss, improve security.

2, because the utility model adopts central controller and corresponding software, improve the accuracy of judging, inform owner simultaneously and, can realize unattended anti-theft feature to public security department's warning by the phone transmission circuit.

Description of drawings

The utility model is described in further detail below in conjunction with drawings and Examples

Fig. 1 is an electrical schematic diagram of the present utility model

Embodiment

Referring to Fig. 1, only institute of the present utility model villa protection alarm device is made up of condenser type human inductor, central controller U1, alarm circuit 4, imaging circuit 5, phone transmission circuit 6 and the software that is complementary.Described human inductor is made up of two open detection lines, signal generating circuit and RC oscillating circuits, and described human inductor output terminal is electrically connected with the RA0 end of central controller.In the present embodiment, surveying line 1 and 2 all is metal wire, article two, survey line keeping parallelism setting substantially, two distances of surveying between the bar line keep about one meter, about 0.3 centimetre of the distance of built on stilts, article two, survey line on the hedge all around that is arranged on only institute or villa or on the enclosure wall, can not short circuit.This detection line allows toy to pass through, and does not allow human body to pass through.Described alarm circuit is electrically connected with RA4, the RB0 end of central controller; Described imaging circuit is electrically connected (RB1, RB2, RB3, RB4 also can be described as pin 7, pin 8, pin 9, pin one 0) with RB1, RB2, RB3, the RB4 end of central controller; Described phone transmission circuit is electrically connected with RB5, RB6, the RB7 end of central controller.Described central controller, alarm circuit, phone transmission circuit are installed in a control enclosure interior (not showing in the accompanying drawing) and place in the room.

Referring to Fig. 1, in the present embodiment, constitute RC oscillating circuit 3 by capacitor C 1, telefault L1, resistance R 1, R2.Constitute signal generating circuit by detection line 1, detection line 2, transistor Q1.Surveying line 1 is connected with the collector of transistor Q1 through telefault L1 capacitor C 4, the resistance R 3 of also connecting on the transistorized collector, transistorized base stage is connected with the bleeder circuit that resistance R 1, R2 constitute, survey between line 1 and the transistorized base stage capacitor C 1 is set, shunt capacitance C3, capacitor C 5 resistance R 4 on the transistorized emitter, the output terminal of transistor Q1 is connected with central controller by commutation diode D1, survey line 2 ground connection, a capacitor C 2 is set between telefault L1 and the capacitor C 4 over the ground.

In the present embodiment, warning circuit can be conventional sound and light alarm module, and this module can adopt U.S. C﹠amp; K company product, described imaging circuit adopts conventional video camera.

In the present embodiment, described central controller adopts PIC16F716 type single-chip microcomputer, and this single-chip microcomputer is the single-chip microcomputer of band AD conversion.Pin RA4, the RB0 of this single-chip microcomputer can be connected (RA4, RB0 also can be described as pin 3, pin 6) with a plurality of audible-visual annunciators (being voice guard, visual alarm) signal as alarm signal output ends.Pin RB5, the RB6 of this single-chip microcomputer, RB7 are connected with modulator-demodular unit (being mobile phone CDMA or gsm module).Also can be connected (RB5, RB6, RB7 also can be described as pin one 1, pin one 2, pin one 3) with cable telephone network by modulator-demodular unit.

In the present embodiment, when human body range sensing line 1 and detection line 2 are very near, perhaps bored, crossed when surveying line, survey line 1 and survey electric capacity between the line 2 concussion frequency that makes the RC oscillator that changes variation has taken place, output terminal at transistor Q1 produces signal and is transferred to single-chip microcomputer, warp is by software analysis, and single-chip microcomputer is connected alarm circuit, control phone transmission circuit is connected owner's the mobile phone or the Advise By Wire owner of setting, and is all right simultaneously to public security department's telephone call.
