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 the mode of opening the door with electronics telecontrol engineering or phone, in the time of normal door, is installed on the power set in door, will promote lockset and move, and realization is opened the door.But retained the mode that mechanical key opens the door, and while avoiding electronic telecontrol or phone to open the door, 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 that the behavior of opening the door is normally to open the door by electronic technology, instead of opens the door with mechanical key.When normal method is used electronic open-door, identification circuit input has electronic signal, and crime behavior identification circuit is inputted without electronic signal, will start warning system.

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

One, power supply is the basis of all electronic equipments, and a good electronic equipment must be equipped with a good power supply, particularly security and anti-theft equipment, can not allow protection occur blank, thereby spy describes to power supply:

Fault display power supply is made up of jointly rectification unit, voltage-stabilizing protection unit, voltage voltage regulation unit, overcurrent protection and display unit, anti-thunder tube, direct current charge/discharge unit; voltage regulation performance is outstanding; in the time of joined device fails, can initiatively show; possess anti-lightning strike function, when without civil power, still can ensure the normal service behaviour of equipment.

1, the reason of energy voltage stabilizing:

Voltage is adjusted triode (8 in Fig. 1) and has been adopted the form of penetrating with output, its emitter voltage differs from 0.7 volt than base stage all the time, and it is irrelevant with collector voltage, once base stage is carried out after voltage stabilizing, voltage is adjusted triode (8 in Fig. 1) and just can be stabilized on the voltage that is similar to base stage, and this numerical value can meet the needs of supporting electronic equipment.

2, this power supply has two kinds of functions of overcurrent protection and monitoring.

This power supply has overcurrent protection function: after supporting equipment generating device damages, the normal fault occurring is that complete machine electric current increases, electric current through overcurrent protection resistance (9 in Fig. 1) increases, when exceeding after the emitter stage and base voltage across poles of overcurrent protection triode (12 in Fig. 1), this overcurrent protection triode can form forward conduction, and amplify, and voltage is adjusted to the base bleeder current of triode, thereby sealing voltage is adjusted the output of triode (8 in Fig. 1), the shunting route of base stage is from the emitter stage of overcurrent protection triode (12 Fig. 1) to colelctor electrode, and after overcurrent protection monitoring indicator lamp (13 in Fig. 1), arrive ground wire.

This power supply can become a kind of reason of monitoring observation device; after its load is excessive, overcurrent protection action, (12 in Fig. 1) is open-minded for overcurrent protection triode; string is bright at the overcurrent protection monitoring indicator lamp (13 in Fig. 1) of overcurrent protection triode (12 in Fig. 1), luminous for people's observation.

Another feature of circuit is, in the time having fault, protection forms automatically, and overcurrent protection monitoring indicator lamp (13 in Fig. 1) is luminous, and fault is while disappearing, automatically recovers.Its reason is that load current is large, and flowing through overcurrent protection resistance (9 in Fig. 1) voltage increases, and overcurrent protection triode (12 in Fig. 1) is automatically open-minded, after Failure elimination, automatically recovers.Had this feature, can get rid of a lot of accidentalia, equipment can not produce mistakenly stop, does not affect normal work.

3, the overvoltage capabilities of this power supply is more much better than than three present end integrated circuits, can normally work at thundery sky, and needn't power-off, its reason have following some:

The one, the base stage voltage-stabiliser tube that voltage is adjusted triode (8 in Fig. 1) adopts face bonded type diode, instead of adopts common voltage-stabiliser tube, not fragile.The 2nd, export the voltage accurate adjustment resistance in adjustable voltage stabilizing branch road, (11 in Fig. 1), because the resistance of this resistance is little, do not affect the voltage regulation result of voltage being adjusted to triode (8 in Fig. 1), but really plays great role to strengthening overvoltage effect.The 4th, in voltage-stabilizing protection unit, be still face in conjunction with diode, not only not fragile, and be to be connected in the adjustable voltage stabilizing branch road of output, save number of diodes.The 4th, much higher more than three end integrated stable voltage circuits because voltage is adjusted the back-pressure of triode (8 in Fig. 1), the former is generally hundreds of volts, and only 30 volts of the latter.The 5th, be equipped with anti-thunder tube, this pipe breakdown protection voltage is tens of volts, after coordinating, thereby has very large surplus with the voltage adjustment triode of high-power high back-pressure.

4, this power supply can be formed on the reason of working under very wide civil power:

Due to this power supply, not to be afraid of input voltage too high, so input voltage can be established and adjusted higherly in the time of design, in the time that civil power is low, at this moment rectification is can not output very low, just can do certain compensation.

5, can adjust the reason of different output voltage stabilizing values.In the adjustable voltage stabilizing branch road of output, the pressure drop of voltage coarse adjustment diode (10 in Fig. 1) is leading role, so can form coarse adjustment, and the shared ratio of the resistance of going here and there is very little, so also can do accurate adjustment, the benefit of accurate adjustment is can the voltage for decimal point of furnishing to the required standard of battery floating charge.

6, more convenient to the adjustment of output voltage stabilizing value, because the face of connecting in the adjustable voltage stabilizing branch road of output is 0.7 volt in conjunction with the each voltage stabilizing value of diode, there is reliable uniformity, can accomplish more accurately and adjust, and resistance can be in 0.7 voltage adjustment, favourable like this batch production.

7, the explanation of direct current charge/discharge unit:

The first, to adjust the emitter voltage of triode be that the voltage of floating charge output point can be adjusted to standard float charge voltage to voltage, because voltage accurate adjustment resistance can be adjusted the voltage below 0.7V, so adjust easily, realize science floating charge, floating charge resistance (14 in Fig. 1) mainly plays two effects, and the one, to large power supply current limliting, the 2nd, realize the voltage isolation between floating charge output point and battery (18 in Fig. 1), thereby in the time having interchange, both can floating charge, can become again working power.

The second, battery tension is standard 12V voltage, but in the situation that alternating current-direct current mixes, battery standard float charge voltage is 13.6V, but when battery discharging, Voltage-output is 12V, when charge and discharge, both voltages are inconsistent, and direct current charge/discharge unit of the present invention has solved this problem well, because discharge diode (17 in Fig. 1) is PNP pipe, when its conducting when battery discharging, the pressure drop of discharge diode is very little, can ignore, and can not produce very large pressure drop, make battery discharging triode with it, can not lose valuable pressure drop.

The principle that formation discharges and recharges is: the base stage of discharge diode has connected resistance to earth (16 in Fig. 1) and controlled diode (15 in Fig. 1) with a rectification output, this circuit just has such principle: when rectification output cathode has voltage, just show now to have alternating current to exist, battery should be floating charge phenomenon, discharge diode is because be PNP pipe, its base stage has voltage to exist, and can conducting, and colelctor electrode does not just have Voltage-output.When rectification output cathode no-voltage, discharge diode base stage no-voltage, it has just formed the form of an electronic switch, forms conducting state, and battery starts electric discharge, and colelctor electrode output voltage is distinguished two stages of floating charge and battery discharging reliably.

Three, balance diode plays an important role in this circuit, because the standard float charge voltage of battery is 13.6V, and operating voltage should be consistent with battery tension, just be unlikely to the storage battery because have a power failure and force down equipment is not worked or cisco unity malfunction, therefore increase the number of balance diode, float charge voltage 13.6V is reduced to 12V left and right, while having alternating current, equipment is normally worked, and when battery, institute arranges for also normally working.And diode is the 0.7V of constant substantially, fine debugging, its dynamic electric resistor is little, little to load effect, can not produce output voltage fluctuation, thereby ensure the correctness of alternating voltage output, and in the time of storage battery power supply, only through the little discharge diode of pressure drop, without balance diode, so can not produce pressure drop, therefore ensure the stable of combined-voltage output.

Two, 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. 2) 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. 2) 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. 2) has high-order output.Triode (013 in Fig. 2) is controlled in this high-order output excitation after integrated amplifier (012 in Fig. 2), opens and drives relay (016 in Fig. 2), 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 in the time having touch signal, preposition integrated circuit is in vibrational stabilization state, and when having after 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, has improved this grade of performance from another angle.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.Make amplifying circuit with integrated amplifier, multiplication factor than discrete component is much bigger, therefore when 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. 2) resistance is large, its sensitivity step-down, resistance is little, sensitivity raises, and has very strong adjustable, compared 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. 2), strengthen 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. 2) of relay to connect power supply, normal pin contact becomes the output (018 in Fig. 2) of integrated amplification early warning circuit.

Three, the lockhole switch of installing, 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 (opening with improper), 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, warning firing switch is sensitive and reliable, can in the time that crime behavior is not accomplished, just report to the police, thereby loss is reduced to minimum.The initiating signal of reporting to the police because the switch contact in the time that touch sheet is being become flexible on lockhole will change.

Four, all very strong tracing properties of onsite alarming device, and in the time of nil case non-transformer, therefore circuit can not damage.In onsite alarming device, use audio-frequency power amplifier, simple in circuits, quiescent dissipation is low, and operating voltage range is wide, and peripheral cell is few, and voltage gain adjustment degree is wide, to advantages such as the distortion factor of sound are low.

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 ensure that early warning system will be started immediately in the time having people to want to destroy lockhole, the 2nd, and load capacity is strong thereby can ensure the embodiment of various early warning effects, and the 3rd, reliably, the life-span is long in use.

2, warning system partial properties is very excellent, and warning system can not be reported by mistake completely.Because after coordinating with existing achievement, there is automatic recognition property.The warning producing when owner is absent from the scene may be only crime behavior.Otherwise the behavior of not committing a crime, switch can not send signal, at this moment because the structures shape of switch is installed.Due to the intrinsic property of switch, in the time that being subject to compressing and not suffering oppression, shift knob there is to occur the variation of contact, lay special stress on protecting the lockhole being the most easily cracked.

3, the power source performance of adapted is good; the blank that there will not be security personnel, is mainly manifested in: the floating current source that (1), band show, can provide stable voltage; again to the standby monitoring effect of having played of arrange; if institute arranges standby breaking down, source current is increased, overcurrent protection monitoring indicator lamp sends light warning immediately; and in the time being fault-free at ordinary times; can not produce warning, if supporting security personnel's product has been avoided security personnel's blank of not knowing because of power failure.

(2), lightning protection and overvoltage capabilities are strong, can not quit work because of thundery sky, selected anti-thunder tube is withstand voltage between tens volts, exceed immediately and disconnected, can not make because of being struck by lightning the component wear in power supply, and triode used is high back-pressure large power triode in power supply, that can bear is withstand voltage at hundreds of volts, has substantially exceeded three traditional end integrated stable voltage circuits.

(3), anti-overflow is effective, protection is large, has reduced voltage and adjust the heating degree of triode.

(4), adaptive faculty is strong, can not damage in the place that civil power is high, also can normally work in the place that civil power is low.

(5), easy to adjust, realized the science floating charge to battery, there is overcurrent protection ability simultaneously.Applicability is strong, easy-to-use supporting with other electronic product, strengthens the performance of electronic product.
