Description

Digital display area wireless liaison net for guarding against theft

The utility model belongs to the wireless anti-theft networking of territory, a kind of digital display area.

At present, the wireless anti-theft networking that utilizes numeral to show has varied, as: patent 88207896.X wireless anti-theft alarming device, 89200713.3 numerical coding multi-path radio warning devices, 89205985.0 digital network alarming devices etc., majority all is that employing infrared ray, ultrasound wave, microwave or trigger probe, accuracy are not ideal enough, occurs misoperation sometimes.

The purpose of this utility model is to adopt the U.S.'s state-of-the-art human body heat release sensor, accuracy height, no misoperation.

The utility model partly is made up of emission and reception two.Emission partly is contained in the stolen position of control, releases a yard device by human body heat release sensor, amplifier, chronotron, archival memory, data-triggered forwarder, transmitter, shutdown and forms.CK ₁For human body heat release sensor, through IC ₂, IC ₃, IC ₄, IC ₅Operational amplifier amplifies shaping to BG ₆Conducting makes F ₁, F ₂The bistable switch upset of forming, F ₃The output high level makes the F Schmidt trigger produce the time clock of 0.5HE, gives IC ₆, IC ₆Be one 2/10 system counter, when receiving that triggering time clock imports, from Q ₀Beginning, (Q one by one ₀～Q ₉) the output high level signal, work as Q ₀Become low level by high level, when Q becomes high level by low level, F ₃The output high level, and be not subjected to front sensor probe signal controlling, Q ₁The high level of output is through F ₇Make F after anti-phase ₈, F ₉The bistable switch upset of forming is through R ₁₈, BG ₃Conducting IC ₇Radiating circuit (module), Q ₃High level is through R ₁₉Make BG ₃End.Digital encoder IC ₁₅Cut off the power supply once, conducting after 0.5 second, preparation redialing geocoding, Q ₅High level is through R ₂₀Make BG ₂Conducting is again through relay normally open contact J ₁Conducting IC ₁₅Redial key, IC ₁₅Just the address digit signal of having finished is delivered to F ₁₀Schmidt's generator is through F ₁₁Deliver to IC ₇Go to adjust transmission frequency, IC ₇High frequency amplifies through C ₁₅Launch to antenna.IC ₈For releasing the code switch circuit, A～A is for releasing code switch, when releasing code switch and writing the address when identical, F ₂₃Input end is high level, is output as low level, through R ₄₀Make BG ₇End, turn off all power supplys of probe and alarm.Human body heat release sensor CK ₁When not receiving human body heat release signal, D ₁, D ₂Be output as low level, IC ₆, IC ₇, IC ₁₅Deng all being in by wait state.GEN, Y ₁Be the chimes of doom generator, when human body heat release movable signal, through F ₃The high level of output is by by R ₄₁, C ₉The chronotron time-delay of forming was sent chimes of doom to drive away the burglar after 1.5 minutes.

Receive and partly to be contained in duty room, by receive head, automatic switch, data repeater, release a yard device, counter, display, alerting signal generator form.IC ₁₀Be the FM reception head, receive frequency and IC ₇Transmission frequency when identical, IC ₇19 pin output low levels make F ₁₂, F ₁₃The bistable switch upset is through R ₂₉Make BG ₅The conducting counter is released the power supply of a yard device, alarm.Address pulse is through receiving an IC ₁₀23 pin pass through C ₁₉, again by IC ₁₆Deliver to audio frequency after computing is amplified and release a yard device IC ₁₁Release sign indicating number, when yard a device frequency and an IC are released in the address ₁₁When the local oscillation frequency is identical, IC ₁₁Output low level is through F ₁₄, F ₁₅, F ₁₆, F ₁₈Deliver to decade counter IC ₁₂Count.By F ₁₇, R ₃₄, D ₅, C ₂₇The delay circuit of forming makes counter IC ₁₂Four (Q ₀～Q ₃) count the address to IC ₁₃, IC ₁₄Count by turns one by one, when counting finishes, through F ₂₂Output low level makes display led demonstrate the precise number at controlled position, makes F simultaneously ₁₉, F ₂₀, F ₂₁And the alarm generator work of peripheral circuit composition, produce and be interrupted rapid alerting signal, through C ₂₉Deliver to IC ₁₀24 pin carry out low frequency and amplify.Alerting signal after the amplification is sent rapid chimes of doom by loudspeaker.

The utility model is without backguy, can be in sound noiseless big zone monitor alarm, cheap, convenient for installation and maintenance, use flexibility and reliability, the advantage of good confidentiality.
