Description

Intelligent anti-theft door

The utility model relates to a kind of security door, be specifically a kind of can be by the intelligent anti-theft door of telephone call.

Present security door has indoor warning device, can't hear warning when owner stays out, and does not reach the purpose of warning.

The utility model provide a kind of intelligent anti-theft door, its burglar alarm can be in time by the Advise By Wire working or the owner in other places, reaching the purpose of the anti-danger of reporting to the police.

The technical solution of the utility model is as follows:

This security door has door leaf, doorframe, lock point; Also be equipped with can be automatically burglar alarm by telephone call;

Above-mentioned burglar alarm is that power supply is through transformer, rectifier, wave filter, stabilizator meets the integrated circuit LM567 that is used for modulation signal respectively, be used to promote the integrated circuit LM386 of loudspeaker and the integrated circuit CD4069 that is used to amplify, triggering signal inserts integrated circuit CD4069, the output of this integrated circuit connects loudspeaker through an electric capacity, this output also meets integrated circuit LM567, the output of LM567 is through integrated circuit LM386, electric capacity connects loudspeaker, another output is through monolithic memory speech recording and reproducing integrated circuit SR9G26, the carrier wave transformer is communicated with local telephone network, the output termination power pushing circuit of integrated circuit LM567, this circuit is published in instalments wave transformer.

Advantage of the present utility model is: 1, this security door is in case by unnormal unlocking, burglar alarm work, send warning by the order that pre-sets through phone, can notify owner by phone, mobile phone, beeper, simultaneously indoor also warning, 2, report to the police rapidly reliably, but monolithic memory integrated circuit repetition of alarms can be monitored house, bank, warehouse etc.

Fig. 1 is the utility model schematic appearance;

Fig. 2 is the block diagram of the utility model burglar alarm;

Fig. 3 is the circuit theory diagrams of the utility model burglar alarm;

Fig. 4 is the monolithic memory audio record circuit schematic diagram of the utility model burglar alarm;

The utility model is described in further detail below in conjunction with accompanying drawing.

Can see that by Fig. 1 this security door has door leaf (7), doorframe (3), lock point (1); The wiring board of burglar alarm is housed in door leaf, and it has outside lead-in wire (2), has holding wire (5) to connect a lock point (6).

Can see that by Fig. 2, Fig. 3 the power supply of burglar alarm is through transformer B ₁, rectifier VD _701-704, wave filter C ₇₀₂, integrated regulator 7808 connect respectively the integrated circuit LM567 that is used for modulation signal 8 pin, be used to promote the integrated circuit LM386 of loudspeaker and 14 pin of the integrated circuit CD4069 that is used to amplify, triggering signal inserts 3 pin of integrated circuit CD4069, the output 8 foot meridian capacitor C of this integrated circuit ₃₀₄, meet loudspeaker YS, this output also connects 3 pin of integrated circuit LM567, the output of LM567 is through 5 pin, the capacitor C of integrated circuit LM386 ₂₀₇, meet loudspeaker YS, another output is through monolithic memory speech recording and reproducing integrated circuit SR9G26, carrier wave transformer B ₂, be communicated with local telephone network, output 5 pin of integrated circuit LM567 meet power pushing circuit VT ₅₀₁, this circuit is published in instalments wave transformer B ₂

Can see the circuit theory diagrams of monolithic memory speech recording and reproducing integrated circuit SR9G26, its PLAYL by Fig. 4 ₁23 pin, PLAYL ₂24 pin, REC are connected on the S of Fig. 3 respectively ₁, S ₂, S ₃On, A ₇-A.It is the entry address of every section recording playback sound, VSSD, VCCD i.e. 12,28 pin are the power supply of digital circuit, VSSA13 pin, VCCA16 pin are the analog circuit power supply, 14,15 pin connect loudspeaker, the answer tube input of 18 pin, 23 pin recording control, low level is effective, 24 pin playbacks control negative pulse is effective, and 27 pin recording control negative pulse is effective, 25 pin recording state index signals.

When door during by improper opening, holding wire input signal at this moment is through L ₅₀₃, L ₅₀₄, C ₅₀₆, R ₆₀₂, C ₆₀₂, C ₆₀₃, deliver to 3 pin of integrated circuit CD4069, amplify, the oscillating circuit that radiating circuit is made up of four phase inverters of integrated circuit CD4069 inside produces alarm signal, through 8 pin output after twice amplification, through resistance R ₃₀₄, resistance R ₁₀₆, capacitor C ₁₀₆Deliver to 3 pin of integrated circuit LM567 and modulate, LM567 is a phase-locked loop circuit, the Resistor-Capacitor Unit R that its 5 pin, 6 pin are connect ₅₀₁, C ₅₀₁, RP ₁Determined the memory function of IC interior, modulated signal is exported by 5 pin, delivers to promote circuit VT ₅₀₁Amplify, again through L ₅₀₂, L ₅₀₃, be coupled in the local network and go, in advance the telephone number that is provided with, phone number etc. are connected by telephone network and are reported to the police.Because integrated circuit SR9G26 has memory function, can repeat to send, guarantee to report to the police and to receive.
