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

The existing achievement technology of inventor is that normal door no longer needs mechanical key, but open the door with electronics telecontrol engineering, thus lockhole can be covered, but also remain the mode of mechanical key enabling simultaneously, can also open the door with mechanical key if electronic telecontrol is opened the door when there is problem.If stranger wants to enter house by cracking lockhole, hand has just contacted lockhole cover plate will produce warning, and oneself because electronic telecontrol goes wrong by the situation that mechanical key opens the door, although warning also can be produced, because one of own side is on the scene, so can not feel alarmed.Also therefore identification circuit can differentiate that to open the door be that the normal door of owner or the preparation of perpetrator crack lockhole and enter room automatically.

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

One, mixed type floating charge source of stable pressure; it is the stabilized voltage supply that alternating current-direct current shares; it contains rectification unit, overvoltage voltage-limiting protection unit, overvoltage fast tripping protection unit, voltage regulation unit, charge/discharge unit and balance diode; civil power is powered to other unit after overcommutation; have run into thunderbolt or overvoltage time; overvoltage fast tripping protection unit starts the fast tripping protection formed overvoltage voltage-limiting protection unit immediately; the voltage-limiting protection of overvoltage voltage-limiting protection unit is then the Supplementary and perfect to pressure fast tripping protection unit, jointly forms the overvoltage protection to voltage regulation unit input end.Charge/discharge unit solves the contradiction that float charge voltage is high and sparking voltage is low, and balances the utilization of diode, achieves alternating current-direct current and shares, be independent of each other again, make it the demand adapting to antitheft series products.

(1), rectification have employed the form of decompression capacitor, decompression capacitor (2 in Fig. 1) withstand voltage for being greater than 100V, then becomes rectification through rectification circuit (3 in Fig. 1) and export, for rear class is powered.

(2), the explanation of overvoltage voltage-limiting protection unit and overvoltage fast tripping protection unit, the principle that namely lightning protection anti-over voltage ability is strong:

Overvoltage voltage-limiting protection unit and overvoltage fast tripping protection unit, constitute " fast tripping protection function ", excellent performance, has very strong lightning protection overvoltage capabilities.

Overvoltage voltage-limiting protection unit is made up of overvoltage voltage-limiting protection triode (4 in Fig. 1), upper inclined resistance (5 in Fig. 1), overvoltage voltage-limiting protection voltage stabilizing diode (6 in Fig. 1); Overvoltage fast tripping protection unit is made up of overvoltage fast tripping protection controllable silicon (7 in Fig. 1), triggering voltage stabilizing diode (8 in Fig. 1).

1, the principle formed is: if be struck by lightning and cause the emitter voltage of overvoltage protection triode too high; after exceeding the door triggering voltage stabilizing diode; trigger voltage stabilizing diode conducting; thus overvoltage fast tripping protection controlled silicon conducting is triggered; immediately to the base stage short circuit of overvoltage voltage-limiting protection triode; make the complete no-output of overvoltage voltage-limiting protection triode, namely 78 serial integrated stable voltage circuit input no-voltages, form lightning protection overvoltage fast tripping protection.

2, fast tripping protection function why is called; because once the emitter voltage of overvoltage protection triode is too high; overvoltage fast tripping protection controllable silicon is itched conducting immediately; and there is very strong positive feedback; can rapidly by the base stage short circuit of overvoltage voltage-limiting protection triode; protection whole process is very rapid, and protection thoroughly, realizes sealing up a door completely.

3, overvoltage fast tripping protection controllable silicon and triggering voltage stabilizing diode form fast tripping protection function, when during normally to work without overvoltage, are in open-circuit condition; there is no electrical wear; can not damage, and trigger the voltage of voltage stabilizing value higher than overvoltage protection transistor emitter of voltage stabilizing diode, so be also open-circuit condition; do not have electrical wear can not damage yet; and once there be overvoltage, start immediately, become fast tripping protection; so in normal state, overvoltage fast tripping protection unit is all standby at any time.

4, the automatic restorability of overvoltage fast tripping protection silicon controlled is good.Reason is after producing protection; overvoltage voltage-limiting protection triode no-output; triggerless voltage; in addition overvoltage fast tripping protection controllable silicon anode has resistance, by automatically losing self-sustaining electric current, reverts to open-circuit condition voluntarily; if be again struck by lightning; again start, form protection, until output voltage is normal value.

5, overvoltage voltage-limiting protection unit defines the voltage-limiting protection function of protection against lightning strikes to thunderbolt, the perfect further protection to integrated circuit.

Its reason is; the base stage of overvoltage voltage-limiting protection triode has overvoltage voltage-limiting protection voltage stabilizing diode over the ground; therefore overvoltage voltage-limiting protection triode exports by clamper; this overvoltage voltage-limiting protection voltage stabilizing diode has carried out pressure limiting to shoving of thunderbolt generation, is the further Supplementary and perfect to " fast tripping protection ".

(3), voltage regulation unit can adjust the explanation of standard float charge voltage value:

Voltage regulation unit is made up of resistance (17 in Fig. 1) inclined under resistance (12 in Fig. 1) inclined in 78 serial integrated stable voltage circuits (9 in Fig. 1), output voltage accurate adjustment, output voltage accurate adjustment.In defeated voltage accurate adjustment, resistance and the use of inclined resistance under output voltage accurate adjustment partially, on reference voltage, can realize output voltage and adjusts flexibly, to realize the normal voltage needed for accumulator floating charge, as 6.6 volts; 13.8 volt etc.

(4), the explanation of charge/discharge unit:

Be made up of floating charge resistance (18 in Fig. 1), accumulator (19 in Fig. 1), discharge diode (20 in Fig. 1), rectify control diode (21 in Fig. 1), base stage controlling resistance (28 in Fig. 1), realize discharging to the science floating charge of accumulator and science.

1, the output of 78 serial integrated stable voltage circuits and the voltage of floating charge point can adjust to standard float charge voltage, realize science floating charge, floating charge resistance mainly plays two effects, one is to large power supply current limliting, two is that the voltage realized between floating charge point and accumulator is isolated, thus when there being interchange, both can floating charge, can working power be become again.

2, accumulator standard float charge voltage is 13.8V, but voltage exports as 12V during battery discharging, and the operating voltage of electronic equipment also can only between 12V, because if operating voltage is higher than 12V, only having in galvanic situation, electronic equipment may because storage battery pressure ratio alternating voltage is low cisco unity malfunction, therefore, when only having direct current, the electric discharge of accumulator can not produce large pressure drop, otherwise electronic equipment cisco unity malfunction, this electronic equipment special to some, as antitheft class, security personnel's series products is very disadvantageous, because antitheft or security personnel become illusory, the consequence produced is serious, and direct current charge-discharge unit of the present invention solves this problem well, because discharge diode is PNP triode, during its conducting and battery discharging time, the pressure drop of discharge diode is very little, for 0.1V, can ignore, very large pressure drop can not be produced, battery discharging triode is made with it, valuable pressure drop can not be lost.

3, the principle forming discharge and recharge is: the base stage controlling resistance of discharge diode and rectify control diode, just there is such principle: have voltage when rectification exports, just show now have alternating current to exist, accumulator should be floating charge state, discharge diode is because be PNP triode, its base stage has because there is high pressure to exist, so can not conducting, collector would not have voltage to export.When rectification exports no-voltage, i.e. discharge diode base stage no-voltage, it just constitutes the form of an electronic switch, forms conducting state, and accumulator starts electric discharge, collector output voltage, so very reliably distinguish two stages of floating charge and battery discharging.

(5), balance diode (30 in Fig. 1) to play an important role in this circuit arrangement, that the voltage of floating charge point is reduced to operating voltage, when there being alternating current, electronic equipment is normally worked, accumulator charges normal, and when only having direct current, be only that DC voltage is without balancing diode, thus can not produce additional pressure drop, alternating current-direct current is independent of each other.And diode is the 0.7V of constant substantially, fine debugging, its dynamic resistance is little, little to load effect, can not produce output voltage fluctuation, thus ensure that the correctness that alternating voltage exports, and when storage battery power supply, only through the discharge diode that pressure drop is little, without balance diode, so pressure drop can not be produced, therefore ensure that combined-voltage exports stable.

Two, the explanation of pre-warning:

The signal amplification circuit be made up of enlarge leadingly triode (02 in Fig. 2), phase inverter, control triode (08 in Fig. 2), driving relay (09 in Fig. 2), the touch signal produced after hand being touched lockhole cover plate carries out shaping amplification, be converted into available electric signal, and then start on-the-spot warning circuit, form early warning, wherein phase inverter is made up of first order phase inverter (03 in Fig. 2) and second level phase inverter (06 in Fig. 2).

1, reliable trigger.Enlarge leadingly triode is large power triode, employing is penetrated with output form, there is very strong Feedback polarity, when the base stage of enlarge leadingly triode has faint signal, namely the touch signal produced after hand contact lockhole cover plate, the output signal of enlarge leadingly triode passes to phase inverter, the voltage that non-type touch signal is converted to standard by phase inverter exports, and then trigging control triode, start and drive relay, drive relay adhesive, drive relay adhesive contact change and start acoustics circuit, and then produce warning.

2, pre-warning is produced reliable in time.Phase inverter quiescent dissipation is extremely low, and during input signal change, can automatic fitration reconcile, so the voltage exported can be protected, antijamming capability is strong, promotes load-carrying ability, reduces time delay, so when there being trigger pip, pre-warning triggers reliable in time.The sensitivity of phase inverter adjusts very well, and a sensitivity adjustment resistance joined by each phase inverter, i.e. 05 in Fig. 2 and 07, and its sensitivity resistor resistance is large, sensitivity step-down, and resistance is little, and sensitivity raises, and has very strong adjustable.

3, the normally opened contact of relay (09 in Fig. 2) is driven to connect power supply, normal pin contact, as output, drives the application of relay, enhances the reliability triggering late-class circuit (being on-the-spot warning circuit) here, small area analysis can be converted to big current by it, triggers late-class circuit more reliable and more stable.

4, further protection is: warn pre-the criminal failing to prevent; if think that further cracking lockhole enters room; just open lockhole cover plate; lockhole switch by the compressing of lockhole cover plate makes shift knob there occurs displacement because of loosening of lockhole cover plate; start warning system, thus send formal warning enabling signal.

Three, formal principle of reporting to the police: be fail to prevent for early warning, or whether crack lockhole crime and design.

Fail to prevent in pre-warning, when continuing to crack lockhole, the button being arranged on the lockhole switch under lockhole cover plate on lockhole, no longer by the compressing of lockhole cover plate, makes contact create change, thus is formed to report to the police and start.

Commit a crime if not by lockhole, but force open the door by other barbarous mode, as door backs down by lifting jack by force, or with noise reduction cutting machine, lock is separated with door, only in right and wrong enabling under normal circumstances, door can start warning immediately with the door switch that doorframe is installed in conjunction with place, and door switch is magnetic switch, is made up of magnet-sensitive switch and magnet segment, the coverage of magnet and magnet-sensitive switch only has 3 centimetres, exceeded this effective value, magnet-sensitive switch contact can change, thus forms startup of reporting to the police.

Door switch and lockhole switch are arranged on two different place's key places respectively, are to form the key of reporting to the police and starting, and make warning more fair and sensible, it shows: 1, can not produce wrong report.When house owner people stays out, the enabling now produced is not normal door, must be crime behavior, and warning is now very crucial, and when owner oneself is opened the door by lockhole with key, because oneself is on the scene, therefore can not make us terrified.

2, be very reliable, the normal life custom of people is affected not, in normal enabling is closed the door, lockhole switch can not action, thus lockhole switch can not damage, and door switch is because have correct electronic recognition signal in normal door situation, so in each normal door situation, need magnet segment and magnet-sensitive switch away from, but can not warning be produced, and open the door and close the door and also do not need artificial additional move, do not affect the normal habits and customs of people, thus do not affect the normal work that security system starts at every turn.

3, be that lockhole switch and door switch are reliably sensitive, just report to the police when crime behavior is not accomplished, thus loss is reduced to minimum.Because when lockhole cover plate loosens, lockhole switch contact will change and send warning enabling signal, the enabling under abnormal condition, door and the firm displacement of doorframe, namely magnet segment is just separated with magnet-sensitive switch, and magnet-sensitive switch sends warning enabling signal immediately.

Four, the explanation of on-the-spot warning circuit: amplifier tube (302 in Fig. 4) is a triode, constitute complementary circuit by a PNP triode (304 in Fig. 4) and NPN triode (305 in Fig. 4) and power amplifier is carried out to audio frequency, when having pre-alarm signal or lockhole switch to have warning enabling signal, open the power supply of on-the-spot warning circuit, so there are voice to produce, what form due to this circuit is an OTL circuit, instead of OCL circuit, so debugging is simple, and have element not perishable, the advantage higher with efficiency, voice sheet (301 in Fig. 4) can record some language in advance, as " please not stopping at this " or " asking speed to be left " etc., and don't the dislike that has nothing to do can be made.

Five, remote annunciator be in family nobody time there occurs event and the protection played, make people learn thing in family outside, allowing security personnel not start a leak.

1, in technical scheme 1, implement remote controlled transmitting circuit scheme, have important meaning, key benefit not easily produces malfunction.Be a very serious thing owing to producing telephone call, if wrong report, unnecessary terrified by causing, consequence is very serious.And remote control is very large by the impact of weather and surrounding environment, because being employed herein remote controlled transmitting circuit scheme, in radio frequency, the copper foil antenna of specific a kind of English lower case n shape coordinates with it, article two, connect with arc Copper Foil kissing above vertical parallel Copper Foil, antenna Copper Foil width is 2 millimeters, the vertical parallel Copper Foil length in two, left and right is 30 millimeters, article two, the spacing of vertical parallel Copper Foil is 20 millimeters, the height that kiss connects the arc Copper Foil of two vertical parallel Copper Foils is 4.5 millimeters, the better coupling that allowed launching and receiving have, experiment proves, being transmitted in like this decreases weather and surrounding environment to a great extent on the impact transmitted.

2, telephone alarm by telephone set, receive programme control circut, interface circuit, form with radio receiver circuit, a few part dresses up one jointly, be arranged in telephone set, its reason is this few part is several parts be closely related, be convenient to receive the signal sent by remote controlled transmitting circuit, notify litigant.Its another reason is that the present invention can realize a tractor serves several purposes, namely can make communication telephones, can realize again relief logical.

In the common communication phone in market, general all have a number storage function, what telephone set designed the argument of this function is easy to use with the telephone number often put through, its reason is if in advance by after often dialling storage key that plane No. code is stored in telephone set, put through often dial time, the mode that multiple key could transfer to the code of long number should be dialled, become and only press the simple and direct form that a key just can transfer to multidigit number, thus use very convenient, because there is such characteristic, thus create important prerequisite for receiving unit implementing measure of the present invention, utilize this characteristic, in advance in phone, store the telephone number of related personnel.

After the invention process, the outstanding advantages possessed is as follows:

One, machinery and electronics perfect adaptation; be used on anti-theft safety door; anti-theft safety door is possessed early warning, formal advantage of reporting to the police, usually both can keep people outside the door, runs into other people when committing a crime; can warning in advance; can formally report to the police again, to " initiatively the protectiveness " that increase anti-theft safety door, be all very significant; so this product finishes the situation of the passive defence of anti-theft safety door completely, improve security personnel's performance of anti-theft safety door all sidedly.

Two, warning function is reliably outstanding, and during input signal change, can automatic fitration reconcile, so the voltage exported can be protected, antijamming capability is strong, promotes load-carrying ability, reduces time delay, highly sensitive, reliable trigger.Attempt when there being people to destroy lockhole crime, just contact lockhole cover plate, early warning type system starts immediately, strengthens the psychological pressure of perpetrator.

Three, startup of reporting to the police is reliably sensitive, shows:

(1), warning system can not be reported by mistake.Because after coordinating with existing achievement, there is automatic recognition property.The enabling produced when owner is absent from the scene may be only crime behavior.Otherwise behavior of not committing a crime, lockhole switch and door switch can not send signal, this is the intrinsic property due to lockhole switch, with caused by the magnetic control character of door switch, when lockhole shift knob is being subject to oppressing and the change that contact occurs inherently to occur when not suffering oppression.And when the distance of magnet segment distance magnet-sensitive switch can make the contact of magnet-sensitive switch change.When without crime behavior, the button of lockhole switch is subject to the compressing of lockhole cover plate, thus lockhole switch contact can not change, and enabling is not under normal circumstances because there being correct identification signal, so door switch can not start warning, and when there being crime behavior, lockhole cover plate souththern pine moves, the button of lockhole switch is no longer by the compressing of lockhole cover plate, thus the contact of lockhole switch there occurs change, thus starts warning, but not enabling under normal circumstances, because magnet segment is separated with magnet-sensitive switch, therefore magnet-sensitive switch contact there occurs change and starts warning.

(2), easy to use, dependable performance, protection is tight, and two switches do not affect normal habits and customs after installing completely, and when without event, switch is standby, the initiative alarming when event occurs.

Four, stop the upper various electrical equipment interference existed of society, make tele-alarm more reliably credible.

Five, advanced in performance, irrelevant with people place distance, notification great efforts, can store multi-section phone, send out mass-sending simultaneously, such benefit can carry out Advise By Wire to multiple personnel, telephone set can, as warning device, general time, be exactly common communication telephones when there is something special.

Six, the use of mixed type floating charge source of stable pressure, makes alarm maintain good workability at any time, is mainly manifested in: 1, lightning protection effect is more much better than conventional anti-thunder tube.Its reason one is lightning protection function.Two is that the model of the anti-thunder tube that " voltage breakdown " is low has not easily been bought, and the model scope of triggering voltage stabilizing diode of the present invention is extremely wide, is easy to " puncturing " magnitude of voltage needed for supporting one-tenth, so be easy to the protection of supporting one-tenth voltage breakdown less than 30 volts.Three is that the present invention has " quick-break " and pressure limiting duplicate protection, thus effective.

2, maintain the advantage of 78 serial integrated stable voltage circuits, enhance the overvoltage capabilities of 78 serial integrated stable voltage circuit input ends.

3, adapt to wide, have wider adaptive faculty than traditional stabilized voltage supply, high at the voltage that meets accident, can not damage.And at voltage, lower ground side and period also can normally work.

4, available adjustment exports the voltage stabilizing value that there is decimal in generation, is convenient to, to the floating charge of accumulator science, realize alternating current-direct current and share, makes equipment ensure that good serviceability at any time.There is overcurrent protection simultaneously, be fruitful or other electronic products supporting after have excellent performance.

5, easily produce.Reason one have employed complex function, and simple in circuits is compact; Two is because the debug point in circuit is few.Three is that debug point very easily quantizes, and debugging scope is loose.

6, cheap, cheap more a lot of than a lot of satisfactory a lot of stabilized voltage supply.
