For the measure that clear interpretation is taked, first make the following instructions:
The principle that phone opens the door is: operator carries out calling with phone opponent machine without, after mobile phone receives bell signal, bell signal is taken out through socket, then be input in two-way function electronic logic circuit and carry out logic transition, the bell signal of " length " and " short " during operation can be transformed into transmitting of opening the door or close the door, sent by multi-code transmitter, after the actuator in door receives remote control command, then carry out corresponding logical action.
As follows to further illustrating of measure:
One, power supply is a key of each electronic product, the power supply used in these family expenses combined type information controller becomes the combined type source of stable pressure of AC/DC after implementing, it has the protection of input formula, good effect is had to resistance thunderbolt, there is the protection of output formula, good protected effect is had to the fault of institute's distributor itself, possesses overcurrent display, when output end current is excessive, in time, shows in time, convenient observation, to process in time, also achieve science floating charge, solve the problem that float charge voltage is high and discharge voltage is low, really accomplish whenever all keep good voltage regulation performance, improve the reliability of electronic product.
One, the cardinal principle of voltage stabilizing:
Voltage stabilizing triode (106 in Fig. 2) is the high-power NPN triode of high back-pressure, have employed the form of penetrating with exporting, there is very strong negative feedback, after voltage stabilizing adjustment branch voltage is determined, the emitter of voltage stabilizing triode exports and just can be fixed in a value, and this numerical value meets the magnitude of voltage needed for charge-discharge circuit.
Two, the principle of input protection:
Input protection triggers voltage-stabiliser tube (103 in Fig. 2) by input protection, input protective resistance (102 in Fig. 2) protects triode (104 in Fig. 2) jointly to form with input.
When there being thunderbolt overvoltage; be mainly reflected in the voltage rising that rectification exports; there is input protective circuit; first the high voltage that rectification exports when being struck by lightning trigger input protection can trigger voltage-stabiliser tube (103 in Fig. 2); and then open input protection triode (104 in Fig. 2); make the input protection triode originally for cut-off state saturated; form the base bleeder current to voltage stabilizing triode (106 in Fig. 2); seal up a door even completely; namely the base voltage of voltage stabilizing triode is zero substantially, allows voltage stabilizing circuit no-output.
Three, the principle of output protection:
When this mainly levies very large to thunderbolt energy, voltage stabilizing triode (106 in Fig. 2) has the protection formed during instantaneous soft breakdown, further promotes lightning protection properties; Primarily of output protection controllable silicon (118 in Fig. 2), output protective resistance (112 in Fig. 2), output protection triggers voltage-stabiliser tube (113 in Fig. 2) and jointly forms with the clamp diode (117 in Fig. 2) of output terminal protecting circuit.
Puncture output triggering voltage-stabiliser tube when rectification output overvoltage after, output protection controllable silicon (118 in Fig. 2) reacts rapidly, respectively shunting is formed to the base stage of voltage stabilizing triode, the output of voltage stabilizing circuit is formed and seals up a door, the output of voltage stabilizing circuit is exported without overvoltage, and when after overvoltage failure vanishes, can recover voluntarily; Because after clamper voltage stabilizing transistor base; its output no-voltage; only has the very little base current of voltage stabilizing adjustment branch road in voltage stabilizing circuit; thus possessing can not self-sustaining possibility; output protective resistance (112 in Fig. 2) is connected to over the ground owing to controlling pole at silicon controlled; the sensitivity of output protection silicon controlled can be adjusted flexibly; make small voltage stabilizing transistor base electric current that output can not be made to protect controllable silicon self-sustaining; therefore, after failure vanishes, output protection controllable silicon can recover voluntarily.
The clamp diode of output terminal protecting circuit here plays a very important role, and according to function and the requirement of this grade of protection, not only needs the base stage of clamper voltage stabilizing triode, also the output of necessary directly clamper voltage stabilizing circuit.Because this level wants clamper two point, so add two clamp diodes (117 in Fig. 2) in the design, not only serve the effect of clamper, also have buffer action, thus corresponding 2 are independent of each other.
Four, the explanation of overcurrent protection display circuit:
Overcurrent protection display circuit shows luminous tube by overcurrent protection resistance and overcurrent protection and forms; mainly levy and break down to working as be equipped with electrical equipment; protection when source current is increased suddenly; when voltage output end electric current increases; overcurrent protection resistance (108 in Fig. 2) pressure drop increases, and overcurrent protection display luminous tube (111 in Fig. 2) conducting immediately, sends light instruction; shunt the base stage of voltage stabilizing triode, the electric current flowing into voltage stabilizing transistor base reduces simultaneously.And voltage output end overcurrent is more, then the base current reduced is more, automatically forms the protection to voltage stabilizing triode.
What five, may occur for protection system gushes pressure reaction problem not rapidly to thunderbolt; this measure also uses voltage-limiting protection voltage-stabiliser tube (105 in Fig. 2); the voltage stabilizing value of this pipe adjusts the magnitude of voltage of branch road higher than voltage stabilizing; therefore when non-overvoltage; be in open-circuit condition; namely be Status of Backups, so can not electrical wear be produced, can not damage.And when rectification output end has thunderbolt to gush pressure; voltage accurate adjustment resistance (109 in Fig. 2) both end voltage in voltage stabilizing adjustment branch road increases; after the voltage stabilizing value of voltage-limiting protection voltage-stabiliser tube; voltage-limiting protection voltage-stabiliser tube is open-minded immediately; again pressure limiting is carried out to the base stage of voltage stabilizing triode, the output of protection voltage stabilizing circuit.
Six, the explanation of charge-discharge circuit:
Namely charge-discharge circuit is carry out charge and discharge to storage battery, galvanic utilization, can allow arrange and standby keep good service behaviour at any time, equipment will not worked because of power failure or power-off, therefore charge-discharge circuit has a very big significance, and is described as follows this:
Charge-discharge circuit is made up of with base stage controlled resistor (130 in Fig. 2) discharge and recharge isolating diode (125 in Fig. 2), discharge and recharge isolation resistance (126 in Fig. 2), storage battery (127 in Fig. 2), discharge diode (128 in Fig. 2), rectify control diode (129 in Fig. 2).
1, the reason of standard floating charge can be realized: the base voltage of voltage stabilizing triode is formed by the voltage coarse adjustment voltage-stabiliser tube of voltage stabilizing triode and the voltage stabilizing of voltage accurate adjustment resistance, voltage coarse adjustment voltage-stabiliser tube is a definite value, voltage accurate adjustment resistance then can adjust within 0.7V, so can adjust the magnitude of voltage needed for floating charge easily.Big current has been isolated in the effect one of discharge and recharge isolating diode and discharge and recharge isolation resistance, and effect two is that the voltage realized between floating charge output point and storage battery is isolated, thus when there being interchange, both can floating charge, and can working power be become again.
2, the reason of voltage drop can not be produced: first during battery discharging, discharge diode is high-power PNP triode, the characteristic of PNP pipe is, when base voltage is low, PNP pipe conducting, one big current flows to collector electrode from the emitter of PNP pipe, collector voltage raises, therefore when rectification exports no-voltage, discharge diode conducting, namely storage battery starts electric discharge, why select PNP pipe, because pressure drop is very little during its conducting, negligible, so can not pressure drop be produced in without alternating current, the collector voltage of discharge diode is equal to battery tension.
Second, discharge diode is in cut-off state at ordinary times, namely storage battery is in floating charge state when there being alternating current, without during alternating current just act on, this is because when there being alternating voltage, voltage is directly inputted the base stage of discharge diode by rectify control diode, because the characteristic of PNP triode, base stage has high pressure to exist, therefore discharge diode can not conducting, so discharge diode is in cut-off state at ordinary times, during without alternating current, rectification exports no-voltage, thus the base stage no-voltage of discharge diode, electric current flows to collector electrode from the emitter of discharge diode, the collector electrode of discharge diode produces voltage, this voltage is equal to battery tension.
The main cause that seven, lower ground just can work with the period at civil power: one is the voltage stabilizing triode in circuit, can not produce additional electrical pressure drop, as long as rectifier output voltage is higher than the output voltage of voltage stabilizing circuit, just can make voltage stabilizing triode operation, just can voltage stabilizing.(illustrate: if adopt the input voltage expansion scheme that traditional triode is connected with three end integrated circuits, three end integrated circuits must be provided normally to work required voltage, also need triode operation voltage, master creates triode supplementary loss voltage so simultaneously.And when civil power is low, this is valuable voltage.) two be because voltage stabilizing triode is high inverse-voltage tube, so can rectifier output voltage can be designed higher, when civil power is low, at this moment commutating voltage can not export very low, just can do certain compensation.
Eight, the purposes of diode (131 in Fig. 2) is balanced, exactly higher float charge voltage is reduced to arranged standby operating voltage, so just can make to arrange standby be standard operating voltage when there being alternating current, and when only having direct current be also standard operating voltage, make to arrange standby service behaviour more stable, why using diode, is because diode is definite value 0.7V, debugging is convenient, is easier to the production of batch.
Two, the two-way function electronic logic circuit in measure can tell the principle of closing gate signal and enabling signal automatically:
User calls out the mobile phone in the utility model, after mobile phone receives bell signal, bell signal is taken out through multi-function jack, then be input in two-way function electronic logic circuit and carry out logic transition, the bell signal taken out is after interface unit (2 in Fig. 1), what first enter is close the resistance in door, this is owing to there being an integrating capacitor (4 in Fig. 1) to need charging in enabling passage, integrating resistor and integrating capacitor define regular hour constant, therefore once there be bell signal, must be first open pass door, close door very simple, after a resistance, only just define signal export, connect in multi-code transmitter the bit line of integrated circuit of encoding, the signal that now remote control sends closes gate signal.
What export when multi-function jack is that the long letter number i.e. cell-phone bell time is long, although there is pass gate signal (this does not form harmful effect to logic) of short duration, once after the time constant of long letter number is greater than the time constant by integrating resistor (in Fig. 1 3) and integrating capacitor (4 in Fig. 1), first inverter (5 in Fig. 1) in enabling passage, the output of first inverter plays two aspects, one be through second inverter (6 in Fig. 1) in enabling passage after again export positive signal, be connected to the bit line of radio transmission coding integrated circuit, the signal that now remote control sends is enabling signal, two are through the signal that clamp diode (9 in Fig. 1) clamper closes door, because this point and the input of closing in door have isolation resistance (8 in Fig. 1), so when the output of closing first not gate in door is low, still can not affect the logic of second not gate closed in door.What think explanation is simultaneously, from the angle of security personnel, close door procedure is conducive to security personnel, and the program of opening the door is unfavorable for security personnel, so can not mistake, so the present invention's long letter number (a long call signal) is opening door operation, be signal operation of closing the door by the call signal of short time, be not easy to occur mistake, because long-time operation has the character of " confirmation ".
And use the benefit of inverter to be that quiescent dissipation is extremely low, during input signal change, can automatic fitration reconcile, so the voltage exported can be protected, antijamming capability is strong, promotes load-carrying ability, reducing time delay, so when there being input end signal, exporting reliable in time.
Three, adopting vibrating sensor to take out the method for cell-phone bell signal, is one of important measures.Because this measure not only reliably can take out bell signal, mobile phone entirety can not be injured, and it is convenient, theory and test explanation, piezoelectric ceramic piece is after specific method and cellular phone combination, can the signal of mobile phone when ring be converted to a kind of faint signal of telecommunication, finally can become the signal source of logical circuit, allow logical circuit produce normal logic.
Four, in technical scheme 1, multi-code transmitter scheme is implemented; key benefit is the various electrical equipment interference of stopping in society; the apparatus of present use remote control is many; as locking of protecting car door; with unblock etc.; all want straighforward operation, just define possible interference source, and adopt many yards just can thoroughly stop this kind of artificial disturbance afterwards.
Its principle that this circuit realizes multi-code transmitter is; When the first end of programme control circut exports high-order, the inverter connected exports and makes the chip select of this coding integrated circuit connected be low, institute's this chip select work, and remaining sheet does not work.When second exports as time high, in like manner only have corresponding chip select work, due to each coding integrated circuit with or door mode be input to modulation triode, so form the form of multi-code transmitter.
Five, mobile phone voltage matches power supply is that voltage stabilizing forms on the basis in alternating current-direct current lightning protection source, and adjust the supply voltage required for mobile phone very easily, circuit is simple, easy to adjust, is used on other power supply also very applicable.
Six, mobile phone sensing body wraps vibration damping thing, can avoid there occurs damage because of clashing into, vibration damping thing can be made by a lot of thing, as cotton goods, foamed plastics etc., load in installation box after mobile phone sensing body is wrapped vibration damping thing together with associated electronic circuits, defining an entirety, being placed within doors to receiving favourable place; Installation box is sealing, and others can not know the cipher by dialing, and oneself can change password easily, so it is reliable for maintaining secrecy.
Following outstanding advantage is had after the invention process:
Both achieved phone to open the door, and achieved again phone and close the door, compensate for existing a lot of product can not phone close the door one large not enough.Can realize the function that phone is closed the door, to the many people easily forgotten things of thing, be still important, can at any time can being closed the door by phone or confirm in any place, making up multiple thing because there is worried existence.User uses and has more the sense of security, is mainly manifested in following several respects:
One, after both-end combined type source of stable pressure is implemented, thunderbolt can not only be resisted, institute's distributor can also be protected, and science floating charge can also be realized, keeping outstanding voltage regulation performance at any time, is a kind of dual-purpose pressurizer of combined type, thus the application space of electronic product can be expanded, it shows: 1, lightning protection effect is remarkable: the protection with multiple lightning protection overvoltage, and first be voltage stabilizing triode is high back-pressure large power triode, inputs higher hundreds of times than the input of common three ends; Second input first reacting output in rectification and voltage stabilizing circuit when being thunderbolt overvoltage, input protection starts rapidly, forms the protection to input; 3rd also has output protection circuit when being overvoltage, has during overvoltage fault and forms shunting to the base stage of voltage stabilizing triode, formed and seal up a door, the output of voltage stabilizing circuit is exported without overvoltage, when after overvoltage failure vanishes, recovers voluntarily the output of voltage stabilizing circuit; 4th is have voltage-limiting protection voltage-stabiliser tube, again carries out pressure limiting to the base stage of voltage stabilizing triode, the output of protection voltage stabilizing circuit.Above-mentioned advantage to much can not the electronic equipment (as the outdoor amplifying stage of cable TV, protector etc.) of power-off arbitrarily significant because they can work at Lei Tian, this is that a lot of stabilized voltage power supply is irreplaceable.
2, there is overcurrent protection Presentation Function, be convenient for people to check in time, improve maintenance efficiency.
3, adapt to wide, have wider adaptive capacity than traditional stabilized voltage power supply, high at the voltage that meets accident, can not damage.And at voltage, lower ground side and period also can normally work.
4, realize alternating current-direct current to share, adjustment exports the voltage stabilizing value that there is decimal in generation easily, realizes the floating charge of storage battery science.There is overcurrent protection simultaneously.
5, simple in circuits, easy scheduling and planning, is convenient to popularize.
Two, phone can be realized open the door, phone can be realized again and close the door, compensate for a large deficiency of existing product.Achieving can the phone function of closing the door, and namely mode of operation opposite house that at any time can be closed the door by phone in any place can carry out confirmation of closing the door, so user can be made to have more the sense of security, because this can make up the deficiency that much may exist.
Three, take out signal reliable and convenient, not by the restriction of mobile phone kind, do not destroy mobile phone body, utilance is high, and can not carry out secondary operations to mobile phone, applicability is strong.
Four, level of confidentiality is high, because the password figure place of mobile phone is many, is more not easily cracked than base, and two is often can change password.
Five, easy for installation, mobile phone adopts radio transmission network Received signal strength, so, place not by the constraint (will the pin interfaces constraint of telephone wire be subject to as adopted base) of environment, do not affect attractive in appearance within doors, also not for its people knows, all bringing benefit to maintaining secrecy, relative section being put into box and defining an entirety, strong security.
Six, stopped the interference that social various electrical equipment is formed, launched reliable.
