One, the principle that phone of the present invention opens the door is, operator calls out the present invention with phone without, mobile phone in the present invention is received after bell signal, through socket, take out, then be input to electronic circuit of the present invention and carry out logic transition, the bell signal of " length " in when operation and " short " can be transformed into the wireless remotecontrol of closing the door or opening the door and transmit, the actuator in door receives after remote control command, then carries out corresponding logical action.
Two, adopting piezoelectric ceramic piece to take out the method for cell-phone bell signal, is one of important measures.Because this measure not only can be taken out bell signal reliably, can not injure mobile phone integral body, and convenient, theory and test explanation, piezoelectric ceramic piece is after specific method and mobile phone combination, can convert mobile phone to a kind of faint signal of telecommunication by the signal when the ring, can finally become the signal source of logical circuit, allow logical circuit produce normal logic.
Three, it is most important point of the present invention that electronic circuit in measure 1 can be differentiated the principle of closing the door with enabling signal automatically, its process is: user calls out the mobile phone in the utility model, mobile phone is after having had bell signal, piezoelectric ceramic piece takes out bell signal, then be input in bielectron switching logic circuit and carry out logic transition, open the door and form by NPN triode and PNP triode with two switching tubes of closing the door, the function that possesses electronic switch, also has amplification effect, the input that is electronic switch has had small curent change, output will produce great variation so.
The effect of clamper triode (105 in Fig. 1) is when the cell-phone bell time is long, be that integrating resistor (103 in Fig. 1) has been less than the time constant of cell-phone bell with the formed time constant of integrating capacitor (104 in Fig. 1), now clamper triode starts, the switching tube clamper of closing the door, door open switch pipe action simultaneously, output enabling signal, the bit line that connects the integrated circuit of encoding in supporting transmitting, what now send is enabling signal, in like manner, when ring time in short-term, be ring time constant be less than integrating resistor (103 in Fig. 1) and the formed time constant of integrating capacitor (104 in Fig. 1), because clamper tube also fails to start, because of but the switching tube action of closing the door, gate signal is closed in output, the bit line that connects the integrated circuit of encoding in supporting transmitting, what now send is to close gate signal, because there has been the effect of clamp diode, because this point and cell-phone bell signal end have the isolation of resistance, so logic is opened the door and is closed gate logic and can not produce disorder.What think explanation is simultaneously, angle from security personnel, the program of closing the door is conducive to security personnel, and the program of opening the door is unfavorable for security personnel, so can not mistake, so long signal (call signal for a long time) is opening door operation for the present invention, by the call signal of short time, be the signal operation of closing the door, be not easy to occur mistake, because long-time operation has the character of " confirmation ".
Four, mixed type floating charge source of stable pressure; it is the shared stabilized voltage power supply of alternating current-direct current; it has comprised 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 over commutation; have while running into thunderbolt or overvoltage; overvoltage fast tripping protection unit starts the fast tripping protection forming overvoltage voltage-limiting protection unit immediately; the voltage-limiting protection of overvoltage voltage-limiting protection unit is to pressing the Supplementary and perfect of fast tripping protection unit, jointly forming the overvoltage protection to voltage regulation unit input.Charge/discharge unit has solved the high and contradiction that discharge voltage is low of float charge voltage, and the utilization of balance diode has realized alternating current-direct current to share, and is independent of each other again, makes it to adapt to the demand of each electronic product.
(1), rectification adopted the form of decompression capacitor, decompression capacitor (402 in Fig. 3) withstand voltage for being greater than 100V, then pass through rectification circuit (403 in Fig. 3) and become rectification output, is rear class power supply.
(2), the explanation of overvoltage voltage-limiting protection unit and overvoltage fast tripping protection unit, the i.e. strong principle of lightning protection anti-over voltage ability:
Overvoltage voltage-limiting protection unit and overvoltage fast tripping protection unit, formed " fast tripping protection function ", and excellent performance has very strong lightning protection overvoltage capabilities.
Overvoltage voltage-limiting protection unit is comprised of overvoltage voltage-limiting protection triode (404 in Fig. 3), upper inclined to one side resistance (405 in Fig. 3), overvoltage voltage-limiting protection voltage stabilizing didoe (406 in Fig. 3); Overvoltage fast tripping protection unit is comprised of overvoltage fast tripping protection controllable silicon (407 in Fig. 3), triggering voltage stabilizing didoe (408 in Fig. 3).
1, the principle forming is: if be struck by lightning, cause the emitter voltage of overvoltage protection triode too high; surpass after the door that triggers voltage stabilizing didoe; trigger voltage stabilizing didoe conducting; thereby triggering overvoltage fast tripping protection controlled silicon conducting; base stage short circuit to overvoltage voltage-limiting protection triode immediately; make the complete no-output of overvoltage voltage-limiting protection triode, 78 serial integrated stable voltage circuit input no-voltages, form lightning protection overvoltage fast tripping protection.
2, why be called fast tripping protection function; once be because the emitter voltage of overvoltage protection triode is too high; the conducting immediately of itching of overvoltage fast tripping protection controllable silicon; and there is very strong positive feedback; can be rapidly by the base stage short circuit of overvoltage voltage-limiting protection triode; protection whole process is very rapid, and protection thoroughly, realizes and sealing up a door completely.
3, overvoltage fast tripping protection controllable silicon and trigger voltage stabilizing didoe and form fast tripping protection function, in the situation without overvoltage when normally working, in open-circuit condition; there is no electrical wear; can not damage, and trigger the voltage stabilizing value of voltage stabilizing didoe higher than the voltage of overvoltage protection transistor emitter, so be open-circuit condition yet; not having electrical wear can not damage yet; once and have an overvoltage, start immediately, become fast tripping protection; so under normal condition, 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 to produce after protection; overvoltage voltage-limiting protection triode no-output; triggerless voltage; in addition overvoltage fast tripping protection controllable silicon anode has resistance, will automatically lose self-sustaining electric current, reverts to voluntarily open-circuit condition; if be again struck by lightning; again start, form protection, until output voltage is normal value.
5, overvoltage voltage-limiting protection unit has formed the voltage-limiting protection function of anti-lightning protection to thunderbolt, further perfect protection to integrated circuit.
Its reason is; the base stage of overvoltage voltage-limiting protection triode has overvoltage voltage-limiting protection voltage stabilizing didoe over the ground; therefore the output of overvoltage voltage-limiting protection triode is by clamper; pressure limiting has been carried out in shoving that this overvoltage voltage-limiting protection voltage stabilizing didoe produces thunderbolt, and is the further Supplementary and perfect to " fast tripping protection ".
(3), voltage regulation unit can be adjusted the explanation of standard float charge voltage value:
Voltage regulation unit in 78 serial integrated stable voltage circuits (409 in Fig. 3), output voltage accurate adjustment partially under resistance (412 in Fig. 3), output voltage accurate adjustment partially resistance (417 in Fig. 3) form.The defeated use of inclined to one side resistance under resistance and output voltage accurate adjustment partially in voltage accurate adjustment can realize output voltage and adjust flexibly, to realize the normal voltage required to storage battery floating charge, as 6.6 volts on reference voltage; 13.8 volt etc.
(4), the explanation of charge/discharge unit:
By floating charge resistance (418 in Fig. 3), storage battery (419 in Fig. 3), discharge diode (420 in Fig. 3), rectification control diode (421 in Fig. 3), base stage controlling resistance (428 in Fig. 3), formed, realize the science floating charge of storage battery and science electric discharge.
1, the output of 78 serial integrated stable voltage circuits is that the voltage of floating charge point can be adjusted to standard float charge voltage, realize science floating charge, floating charge resistance mainly plays two effects, the one, to large power supply current limliting, the 2nd, realize the voltage isolation between floating charge point and storage battery, thereby when having interchange, both can floating charge, can become working power again.
2, storage battery standard float charge voltage is 13.8V, but during battery discharging, Voltage-output is 12V, and the operating voltage of electronic equipment also can only be between 12V, because if operating voltage is higher than 12V, only having in galvanic situation, electronic equipment may be because storage battery pressure ratio alternating voltage be low cisco unity malfunction, therefore, when only having direct current, the electric discharge of storage battery can not produce large pressure drop, otherwise electronic equipment cisco unity malfunction, the electronic equipment that this is special to some, as antitheft class, security personnel's series products is very disadvantageous, because antitheft or security personnel become illusory, the consequence producing is serious, and direct current charge/discharge unit of the present invention has solved this problem well, because discharge diode is PNP triode, during its conducting during battery discharging, the pressure drop of discharge diode is very little, for 0.1V, can ignore, can not produce very large pressure drop, with it, make battery discharging triode, can not lose valuable pressure drop.
3, forming the principle discharging and recharging is: diode is controlled in the base stage controlling resistance of discharge diode and rectification, just there is such principle: when rectification output has voltage, just show now to have alternating current to exist, storage battery should be floating charge state, discharge diode is because be PNP triode, its base stage has because there is high pressure to exist, thus can conducting, and collector electrode does not just have Voltage-output.When rectification output no-voltage, i.e. discharge diode base stage no-voltage, it has just formed the form of an electronic switch, forms conducting state, and storage battery starts electric discharge, and collector electrode output voltage, so distinguish very reliably two stages of floating charge and battery discharging.
(5), balance diode (430 in Fig. 3) plays an important role in this circuit, that the voltage of floating charge point is reduced to operating voltage, when having alternating current, electronic equipment is normally worked, storage battery normally charges, and while only having direct current, is only that direct voltage is without balance diode, thereby 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 electric resistor is little, little to load effect, can not produce output voltage fluctuation, thereby guaranteed the correctness of alternating voltage output, and when storage battery power supply, only through the little discharge diode of pressure drop, without balance diode, so can not produce pressure drop, therefore guarantee the stable of combined-voltage output.
Five, mobile phone voltage matches power supply is that voltage stabilizing forms on the basis of mixed type floating charge source of stable pressure, adjusts very easily the needed supply voltage of mobile phone, and circuit is simple, easy to adjust, is used on other power supply also very applicable.
Six, mobile phone vibrating sensing body is put into vibration damping bag, can avoid producing and damaging because clash into, vibration damping bag can be made by a lot of things, as cotton goods, foamed plastics etc., after being wrapped to vibration damping bag, mobile phone vibrating sensing body packs into together with electronic circuitry involved in installation box, formed an integral body, be placed within doors to receiving favourable place; Installation box seals, and others can not know the cipher by dialing, and oneself can change easily password, so maintain secrecy, is reliable.
After the invention process, there is following outstanding advantage:
One, the present invention can realize phone and opens the door, and can realize again phone and close the door, and what made up that existing a lot of product can not phone closes the door is one large not enough.Can realize the function that phone is closed the door, the people how thing is easily forgotten things, still feels important, because of any place at any time, can be closed the door or be confirmed by phone, makes up multiple thing because there is worried existence.User uses and has more the sense of security.
Two, the mixed type floating charge source of stable pressure lightning protection effect of adapted is more much better than conventional anti-thunder tube.Its reason one is that lightning protection function is and rear class quick-break rather than shorted to earth, to prime without negative role.The 2nd, the model of the anti-thunder tube that " puncture voltage " is low is difficult for having bought, and the model scope of triggering voltage stabilizing didoe of the present invention is extremely wide, is easy to required " puncturing " magnitude of voltage of supporting one-tenth, so be easy to the protection of supporting one-tenth puncture voltage below 30 volts.The 3rd, the present invention has " quick-break " and pressure limiting duplicate protection, thereby effective, and it is in particular in:
1, the advantage that has kept 78 serial integrated stable voltage circuits, has strengthened the overvoltage capabilities of 78 serial integrated stable voltage circuit inputs.
2, adapt to widely, than traditional stabilized voltage power supply, have wider adaptive capacity, high at the voltage that meets accident, can not damage.And also can normally work in the lower place of voltage and period.
3, available adjustment output, for the voltage stabilizing value that has decimal, is convenient to the floating charge of storage battery science, realizes alternating current-direct current and shares, and makes equipment guarantee at any time good service behaviour.There is overcurrent protection simultaneously, and be fruitful or other electronic products have excellent performance after supporting.
4, easily produce.Reason one is to have adopted complex function, and simple in circuits is compact; The 2nd, because the debug point in circuit is few.The 3rd, debug point very easily quantizes, and debugging scope is loose.
5, cheap, cheap more a lot of than a lot of satisfactory a lot of stabilized voltage power supplys.
Three, coordinating of electronic circuit and mobile phone, excellent performance.Clamshell doors can accurately be recognized with pass gate signal, to the precise control of encoding, so it is reliably sensitive again with two functions of opening the door to close the door.
Four, the mobile phone of any type can take out signal easily, does not destroy mobile phone body, and applicability is strong.
Five, level of confidentiality is high, because the password figure place of mobile phone is many, than base is more difficult, is cracked, and can also often change password, and coefficient of safety is high.
Six, in bielectron switching logic circuit, there are two electronic switching circuits, form symmetry, when possessing the characteristic of electronic switch, there is again amplification, simple and reliable.
Seven, relative section is put into box and formed an integral body, strong security.
