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.
According to the existing achievement technology of inventor, in normal door situation, door is separated with doorframe, door switch can not produce warning enabling signal, but not normal door, door is subjected to displacement with doorframe, and door switch contact changes and produces warning enabling signal, and also therefore differentiating opens the door is that the normal door of owner or perpetrator commit a crime enabling.
The power supply implemented in this measure is can voltage stabilizing; monitoring and protecting can be formed again at the input of three-terminal voltage-stabilizing circuit and output both-end; while the series of advantages ensureing three-terminal voltage-stabilizing; fast tripping protection is implemented at the two ends of three terminal regulator; monitor constantly; there are being thunderbolt or unexpected overvoltage; also or three damageds on end bad; fast tripping protection can be started in time; reduce the fault rate that power supply produces, formation is monitor, is again protector simultaneously; can also the power supply of voltage stabilizing, make anti-theft device no longer need simulated conditions to detect whether to damage.
For this reason, the existing meaning to each technical measures of the present invention, concrete condition is explained as follows further:
One, two point form monitoring and protecting type three-terminal voltage-stabilizing power supply is by full-wave rectifying circuit, two-end-point overvoltage observation circuit, and perform control circuit, amplifying circuit, three-terminal voltage-stabilizing circuit forms jointly.The commutation diode that wherein full-wave rectifying circuit is used only has two; circuit is simple; contain input overvoltage monitoring in two-end-point overvoltage observation circuit to start branch road and adjustable monitoring of output and start branch road; the monitoring forming overvoltage at the output of rectification output end and three-terminal voltage-stabilizing circuit starts; perform control circuit and amplifying circuit, form the fast tripping protection to three-terminal voltage-stabilizing circuit and equipment.Three-terminal voltage-stabilizing circuit is outstanding mu balanced circuit, and its external piece is few, and voltage stabilizing is reliable; but input terminal voltage is not high; can not more than 36V, and gushing pressure or unexpected rectifier output voltage being raised when no matter being thunderbolt, all can more than 36V; and for the damage of three-terminal voltage-stabilizing circuit; also monitor, therefore, namely this power supply is voltage-stabilized power supply; also be protection power source, a kind of monitor especially.
A, input overvoltage form the principle of monitoring with fast tripping protection.
Two-end-point overvoltage observation circuit is monitored by input overvoltage and is started branch road and adjustable monitoring of output starts branch road and form: it is formed monitors the input of three-terminal voltage-stabilizing circuit and output two-end-point, and initiatively forms protection when there being overvoltage.
(1), input monitoring and the explanation protected.
1, pressure is gushed when rectification has, door voltage-stabiliser tube (111 in Fig. 2) conducting, indicator lamp one (112 in Fig. 2) sends light instruction simultaneously, make the control triode in execution control circuit (115 in Fig. 2) saturated, its current collection very low level, the base stage of the amplifying triode (107 in Fig. 2) in clamper amplifying circuit, makes the emitter stage of amplifying triode no longer include output.
2, due to the voltage stabilizing value of door voltage-stabiliser tube, can find easily, so threshold value height meter flexibly, also can implement very easily.
The rectification output end overvoltage of 3, gushing under pressure or fortuitous event due to this thunderbolt can recover, because it is not the damage of circuit, therefore when the thunderbolt past, or fortuitous event disappears, and so gushes pressure and can disappear with overvoltage, and after these situations disappear, the base stage trigger voltage controlling triode disappears, and controls the triode also cut-off by saturation recovery, the no longer base stage of clamper amplifying triode, amplifying triode recovers to provide voltage to three-terminal voltage-stabilizing circuit, and therefore circuit can self-healing.
(2), output overvoltage forms monitoring and the principle explanation protected.
Monitoring that output is adjustable starts an adjustable mu balanced circuit of route, indicator lamp two (123 in Fig. 2), trigger resistance (124 in Fig. 2) composition.
Inclined protective resistance (118 in Fig. 2) in route, upper inclined adjustable resistance (119 in Fig. 2), lower inclined protective resistance (122 in Fig. 2), collector resistance (121 in Fig. 2), adjustable triode (120 in Fig. 2) composition are propped up in adjustable voltage stabilizing.
The one protection that this protection produces after mainly checking three end integrated stable voltage circuit internal damage; if three end integrated stable voltage circuits damage; its voltage stabilizing value exported inherently raises; then load is produced to the serious harm of overvoltage; owing to being the keypoint part of power supply usually fault infringement, so be necessary carrying out separately monitor and protecting.
1, the principle formed: after output end of pressure-stabilizing voltage raises; the threshold voltage that adjustable voltage stabilizing branch road is formed is broken through; the circuit that indicator lamp two (123 in Fig. 2) is connected with circuits for triggering (124 in Fig. 2) directly starts and controls triode (115 in Fig. 2); make control triode saturated rapidly; the base stage of the amplifying triode (107 in Fig. 2) of clamper three-terminal voltage-stabilizing circuit (117 in Fig. 2) input; rapid powered-down, and form protection.
2, line feature analysis: the door of this point protection adopts continuously adjustable triode analog circuit, so protective adaptation face is very wide.
For 78 series, three end integrated stable voltage circuit voltage stabilizing values are different, as voltage stabilizing value has 5 volts respectively, and 6 volts, 8 volts 12 volts, so the standard of overvoltage is different.And the Zener diode of correspondence is bad coordinates therewith.Because the threshold value of three end integrated stable voltage circuit output protection branch roads have employed continuously adjustable triode analog circuit; the threshold value of the Zener diode of its simulation is selected flexibly and continuously adjustabe; thus the standard of design protection can be formulated flexibly; can not be restricted, so all three end integrated stable voltage circuits can be adapted to.The principle formed is, after the upper inclined resistance resistance of this pipe increases, on this resistance, dividing potential drop increases; the dividing potential drop of base stage and emitter stage reduces, also because the protection controllable silicon of three end integrated stable voltage circuit outputs has the strong positive feedback arranged, so protection is avalanche type; very rapid, protection is strong.
B, there is the explanation of the multiple protection of overvoltage.
In this circuit, cross and be pressed with multiple protective, first is the monitoring that input overvoltage monitoring starts branch road, and then starts formation protection.
Second is in the base stage of amplifying triode (107 in Fig. 2), be furnished with backup voltage-stabiliser tube (110 in Fig. 2), Main Function be when have thunderbolt or other fault cause gush pressure time, voltage-limiting protection is again carried out to the input of three terminal regulator.The output of rectification have passed through the input that amplifying circuit just enters three-terminal voltage-stabilizing circuit, and in amplifying circuit, the voltage stabilizing value that the voltage stabilizing value backing up voltage-stabiliser tube is in series higher than adjustment voltage-stabiliser tube (108 in Fig. 2) and adjusting resistance (109 in Fig. 2), so back up voltage-stabiliser tube when rectification exports by clamping state, it is open circuit, backup voltage-stabiliser tube is in resting state, if rectification output end has when gushing pressure, the pressure drop at regulating resistor two ends increases, now back up voltage-stabiliser tube again to base stage pressure limiting, the emitter stage of amplifying triode would not export too high voltage, protect the input of three-terminal voltage-stabilizing circuit.The benefit of such design is, backup voltage-stabiliser tube, when non-overvoltage, is in open-circuit condition, does not produce " electrical wear ", do not damage, and is a kind of " backup is awaited orders " state, thus when rectification overvoltage, can plays one's part to the full, and produces unexpected possibility and reduces.
3rd is amplifying triode is high back-pressure large power triode, and lightning protection effect is good.
Its reason is; this pipe breakdown reverse voltage is usually at hundreds of volt; and 78 serial back-pressures are generally 30 volts; more than 10 times to be exceeded than 78 conventional series; so have remarkable power of endurance to overvoltage; adequately protected three-terminal voltage-stabilizing circuit, and three-terminal voltage-stabilizing circuit can not be damaged because input terminal voltage is too high.
The luminous tube of the different colours that C, indicator lamp one with instruction two are, therefore judges it is that front end or rear end there occurs fault very well, is suitable for and reliable.
Two, warning in advance, is expert at crime prevention for before.Attempt to crack lockhole to enter when there being people, because lockhole covers, therefore hand has just contacted lockhole cover plate and has just produced pre-warning, on-the-spot warning circuit starts immediately, sends warning, reminds perpetrator house owner people early to have defence, receive hand as early as possible to be also able to do in time, produce the principle of warning in advance.
Signal shaping early warning circuit is made up of enlarge leadingly triode (02 in Fig. 3), phase inverter, control triode (08 in Fig. 3), driving relay (09 in Fig. 3), and wherein phase inverter is made up of first order phase inverter (03 in Fig. 3) and second level phase inverter (06 in Fig. 3).
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, during input signal change, can automatic fitration reconcile, i.e. shaping, so the voltage exported can be protected, antijamming capability is strong, promotes load-carrying ability, reduce time delay, so when there being triggering signal, pre-warning has triggered reliable in time.The sensitivity of phase inverter adjusts very well, a sensitivity adjustment resistance joined by each phase inverter, i.e. first sensitivity adjustment resistance (05 in Fig. 3) and second sensitivity adjustment resistance (07 in Fig. 3), its sensitivity resistor resistance is large, sensitivity step-down, resistance is little, and sensitivity raises, and has very strong adjustable.
3, the constant open contact of relay (09 in Fig. 3) is driven to connect power supply, transfer 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.
Three, there is further protection.
The criminal failing to prevent is warned for pre-, if think that further cracking lockhole enters room, has just opened lockhole cover plate, the lock-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.
Lock-switch is a key in the present invention, exactly because there has been lock-switch, just made warning of the present invention accomplish more scientific, be also the place different from a lot of alarm, its reason is:
1, wrong report can not be produced.When house owner people stays out, the enabling now produced is not normal door, if now crack lockhole to open the door, must be crime behavior, warning be 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, lock-switch can not action, thus lock-switch can not damage, 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 lock-switch is 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, lock-switch contact will change and send warning enabling signal.
Four, cruelty enters room, and as rushed open by door with jack, this is also a kind of way of committing offenses, and for this cruelty crime, the present invention also can produce warning.This is because be equipped with door switch, door switch can not produce warning enabling signal when normal door, therefore can not affect the habits and customs of people, also without the need to the additional move of people, and be not normal enabling, door and doorframe have just been separated, door switch can start immediately, sensitive and reliable.
Five, the explanation of on-the-spot warning circuit: the power supply of acoustic scene warning circuit is drawn by signal shaping early warning circuit, door switch transfer contact lead-out wire and lock-switch transfer contact and provided, therefore all very strong tracing properties, and when nil case non-transformer, therefore circuit can not damage.Audio-frequency power amplifier is used in acoustic scene warning circuit, simple in circuits, quiescent dissipation is low, and operating voltage range is wide, and peripheral cell is few, voltage gain adjustment degree is wide, to advantages such as the distortion factor of sound are low, acoustical generator can be loudspeaker also can be the piezoelectric ceramic piece being with audio communication box, and voice sheet (201 in Fig. 5) can record some language in advance, as " please not at this stop " or " please speed leave " etc., and don't the dislike that has nothing to do can be made.
After the invention process, improve the security performance of anti-theft safety door, outstanding advantage is as follows:
1, after the invention process; anti-theft safety door and alarm achieve the combination of science; possesses the advantage of two kinds of protectors; usually both people can be kept outside the door; run into other people when committing a crime; two kinds of warnings can be sent; to " initiatively the protectiveness " that increase anti-theft safety door; (its implication is; function of the present invention will produce crime behavior and suppress; and whether wait for its destruction passively) and 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.
2, 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.
3, 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, lock-switch can not send signal, and this is the intrinsic property due to lock-switch, and the change of contact occurs inherently to occur when lock-switch button is being subject to compressing and is not suffering oppression.When without crime behavior, the button of lock-switch is subject to the compressing of lockhole cover plate, and thus lock-switch contact can not change, and when there being crime behavior, souththern pine moves lockhole cover plate, the button of lock-switch is no longer by the compressing of lockhole cover plate, thus the contact of lock-switch there occurs change, thus starts warning.
(2), easy to use, dependable performance, protection is tight, and lock-switch does not affect normal habits and customs after installing completely, and when without event, lock-switch is standby, the initiative alarming when event occurs.
(3) door switch is sensitive and reliable, can not produce warning enabling signal, therefore can not affect the habits and customs of people when normal door, also without the need to the additional move of people, and not being normal enabling, door and doorframe have just been separated, and door switch can start immediately.
4, on-the-spot warning circuit tracing property is strong, simple in circuits, and quiescent dissipation is low, and peripheral cell is few, easily produces and installs.
5, the quality of power supply, directly has influence on overall performance.Power source performance is good, then overall performance is good.Power supply be also usually the normal keypoint part damaged, so the fault rate of power supply can be greatly reduced after adopting this circuit, so be very significant.Its advantage is as follows:
(1), source of stable pressure voltage regulation result is good.Can provide stable voltage, because this circuit is three end integrated stable voltage circuits, this circuit is a kind of outstanding integrated regulator, and voltage regulation result is good, and again containing multiple protection, so be a kind of outstanding mu balanced circuit.
(2), reliable operation, one is three-terminal voltage-stabilizing collector is a kind of integrated stable voltage circuit of maturation, reliable operation.Two is devices that controllable silicon used in circuit and triode belong to ripe, because of but reliable, three is that each circuit peripheral circuit is simplified, so failure condition is few.
(3), in this circuit, cross and be pressed with multiple protective: first is the monitoring that input overvoltage monitoring starts branch road, monitor the monitoring starting branch road, and then start formation protection with output is adjustable.
Second is in the base stage of amplifying triode (107 in Fig. 2), be furnished with backup voltage-stabiliser tube (110 in Fig. 2), is being in Status of Backups at ordinary times, when rectification output end has overvoltage, just starts and again forms voltage-limiting protection to amplifying triode.Thus the unexpected possibility of generation is reduced.
3rd is amplifying triode is high back-pressure large power triode, and lightning protection effect is good.
Its reason is; this pipe breakdown reverse voltage is usually at hundreds of volt; and 78 serial back-pressures are generally 30 volts; more than 10 times to be exceeded than 78 conventional series; so have remarkable power of endurance to overvoltage; adequately protected three-terminal voltage-stabilizing circuit, and three-terminal voltage-stabilizing circuit can not be damaged because input terminal voltage is too high.
(4), output is adjustable, and monitoring startup branch road can adjust starting resistor easily, is applicable to different three-terminal voltage-stabilizing circuit.
(5), both-end forms and monitors constantly, when there being fault, because the light color that sends of the monitoring indicator lamp that two ends use is different, therefore judges it is which place goes wrong very well, using more extensive.
(6), this circuit-line more simplifies, and cost is low, easily produces and debugging.
