For having a clear understanding of the meaning of the technical program, first will make the following instructions:

When the existing achievement technology of inventor is normal door without mechanical key, but use electronics telecontrol engineering, but retained the mode that mechanical key opens the door, avoid electronic telecontrol to break down, can also open the door, so lockhole is covered, and this situation is own on the scene, so also can not feel alarmed even if produce alert sound.

Have identification circuit, can correctly identify is the situation of crime behavior or owner's normal door.Its reason is normal method while opening the door, and identification circuit input has electronic signal, and the input of crime behavior identification circuit is without electronic signal, will start warning system.

A kind of source of early warning of dynamo-electric combination, used a kind of transmitting of stopping various electrical equipment interference to coordinate with it, at the beginning of being formed on crime, just produce pre-warning, fail to prevent, no matter crack lockhole or cruelty is forced open the door, can formally report to the police, and notify in time personnel outside, solved the shortcoming that people does not know thing in family outside, perfect security personnel's performance of anti-theft security door product.

For this reason, the existing meaning to each technical measures of the present invention, concrete condition is further explained as follows:

One, pre-alarming effect of the present utility model is remarkable, and warning device is reliable, is a kind of multi-level alarming device.

Hand rigidly connects tactile touch sheet, sends immediately pre-warning, and criminal is produced at heart pressure and stopped, if making it to understand continues, must be to lose more than gain, probably impel it to stop as early as possible, halt, so played the initiatively effect of protection at this point.

1, the principle that early warning produces: preposition integrated circuit (06 in Fig. 1) forms a kind of oscillating circuit with oscillating element, when hand contact touch sheet, touch signal is through electric capacity, this electric capacity is the commissure electric capacity (02 in Fig. 1) between touch sheet and preposition integrated circuit, enter preposition IC interior, produce accurate vibration, cause vibration failure of oscillation or seriously change, the OUT pin that makes preposition integrated circuit is that preposition output (07 in Fig. 1) has high-order output.Triode (013 in Fig. 1) is controlled in this high-order output excitation after integrated amplifier (012 in Fig. 1), opens and drives relay (016 in Fig. 1), starts onsite alarming device sounding.

2, integrated amplification early warning circuit is outstanding reliable:

(1), preposition integrated circuit is reliable, touch-sensitive, in the present invention of its reason, preposition integrated circuit is not when having touch signal, preposition integrated circuit is in vibrational stabilization state, and after having touch signal, great change must occur oscillatory work state, output must have high-order output.The output direct-to-ground capacitance of preposition integrated circuit has interference effect, from another angle, has improved this grade of performance.Preposition integrated circuit is being structurally combined into of analog circuit and digital circuit, analog functuion and logic function compatibility are integrated, produce accurate vibration, can share a power supply with integrated amplifier, and preposition integrated circuit maximum output current selects 200mA, carrying load ability is strong, and use is reliable, the life-span is long.

(2), amplifying stage has outstanding performance.With integrated amplifier, make amplifying circuit, multiplication factor than discrete component is much bigger, therefore after hand contact lockhole cover plate, preposition integrated circuit has output, through the amplification of integrated circuit, triggers and controls triode, start and drive relay, drive relay adhesive, drive relay adhesive contact to change and start acoustics circuit, and then producing warning.

3, the pre-warning of generation is sensitive reliable.The fine adjustment of sensitivity of integrated circuit, sensitivity adjustment resistance (09 in Fig. 1) resistance is large, its sensitivity step-down, resistance is little, sensitivity raises, and has very strong adjustable, compares with the amplifying circuit of discrete component, circuit is simpler, adjusts more conveniently, and performance is stronger.

Drive the application of relay (016 in Fig. 1), strengthened the reliability that triggers late-class circuit, it can be large electric current by little current conversion, trigger late-class circuit more reliable and more stable, drive the constant open contact (017 in Fig. 1) of relay to connect power supply, normal pin contact becomes the output (018 in Fig. 1) of integrated amplification early warning circuit.

Two, door switch and the lockhole switch installed, stable performance, shows: the one, can generation not make us terrified wrong report, this is the most important.Its reason is, the door that owner is absent from the scene is within doors opened (with improper, opening), is all crime behaviors, and warning is now all very significant.

The 2nd, very reliable, because the opening the door at closing time of normal life, do not need artificial additional move, do not affect the normal habits and customs of people, thereby do not affect the normal work of the each starting of security system.

The 3rd, sensitive and reliable, can when crime behavior is not accomplished, just not report to the police, thereby loss is reduced to minimum.Lockhole switch, at touch sheet switch contact on lockhole when loosening initiating signal of reporting to the police that will change, is reported to the police thereby form, and is encouraged radio transmitter circuit to send alarm signal.And in identification circuit input opening the door during without electronic signal, when door and doorframe souththern pine moving, the door switch contact product initiating signal of reporting to the police that can change, thus form warning, and encourage radio transmitter circuit to send alarm signal.

Three, the distance of transmitting is that sensitivity and weather have a significant impact, and the utility model is very high to the requirement of sensitivity, if by traditional method for designing, very difficult assurance meets designing requirement of the present invention, its reason is, general transmitting can Iterim Change position and the distance of transmitting, as long as can meet at that time reception, can receive that signal just could.And transmitting of the present invention and receiving position are definite, in use procedure, can not change because of the difference of weather, (can affect like that normal life is breezy is used to), once at bad weather temporarily, just be difficult to guarantee the performance of product, so essential, increase necessary measure.And the present invention can largely improve sensitivity, be the copper foil antenna of specific a kind of English lower case n shape, allow transmitting have better coupling with reception.

Four, in telephone alarm, have two kinds of electronic circuits, a kind of is radio reception circuit, and what its energy reliable reception sent from the multi-code transmitter starting of reporting to the police transmits; Another kind is to receive programme control circut, connects the lead-out wire from telephone key rosette copper paper tinsel.

Dialing integrated circuit in telephone has following function, the one, can store a plurality of telephone numbers, in the situation that prior oneself storage is complete (the present invention can utilize former existing phone to store this integrated circuit), as long as being stored to pin, it adds a triggering signal, this sheet will automatically be controlled and send a phone number dial, so being connected on respectively, its a plurality of storage number ends receive on a plurality of outputs in programme control circut, the dialing output of this integrated circuit has been connected on telephone, the model of a lot of dialing integrated circuits has powerful storage number function, a lot of integrated circuit storage capability are all at 10 more than number, so phone circular function is very powerful.

Five, all very strong tracing properties of onsite alarming device, and when nil case non-transformer, so circuit can not damage.In onsite alarming device, by a triode, formed prestage, by a PNP triode and NPN triode, formed complementary circuit audio frequency has been carried out to power amplifier, when having pre-alarm signal, the power supply of having opened this part is controlled in its output, so have voice to produce, due to this electric circuit constitute be an OTL rather than OCL circuit, so debugging is simple, and have element not perishable, and the higher advantage of efficiency.

Anti-theft safety door presents a kind of brand-new looks, has following outstanding advantage:

Possess initiatively protection, with alarm scientific matching, at ordinary times, stranger is kept outside of the door, prevent there being people just can send pre-warning at the beginning of committing a crime, and continue to commit a crime, can send formal warning.Be through with the completely situation of the passive defence of anti-theft safety door, has promoted security personnel's performance of anti-theft safety door all sidedly, is mainly manifested in following several respects:

1, early warning performance is outstanding.Reason one is highly sensitive, can guarantee that early warning system will be started immediately when having people to want to destroy lockhole, the 2nd, and load capacity is strong thereby can guarantee the embodiment of various early warning effects, and the 3rd, reliably, the life-span is long in use.

2, door switch and lockhole switch are sensitive reliable: having people to want to enter room by barbarous mode, door is separated with doorframe, and alarming starter also can promote sound system, sends warning.Lockhole switch, does not need artificial additional move, and (as opened the door at every turn, closing involution behind the door), does not affect the normal habits and customs of people, thus do not affect the each starting of security system normal work.

3, notify advanced in performance, convenient and swift, and with people place range-independence, report great efforts, can store multi-section phone, send out mass-sending simultaneously, such benefit is to carry out Advise By Wire to a plurality of personnel, telephone can, as warning device, general time, be exactly common communication telephones when there is something special.Each phone is repeatedly called out, can be discharged many objective unfavorable factors, notify from a phone call great efforts.After closing of the circuit, not only there is voice message, and can monitor acoustic scene, true feeling is strong.Telephone still has all communication functions of phone, and a tractor serves several purposes does not increase ornaments and the apparatus of family, does not affect life and the custom of family, and family does not have too much ornaments and affects attractive in appearance.

4, the utilization of wireless remotecontrol radiating circuit, has improved remote-control sensitivity, makes launching effect better.
