As follows to further illustrating of above measure:
One, the principle that phone of the present invention opens the door is, operator calls out the present invention with phone without, the present invention receives after bell signal, conversion through transducer has produced into the signal of telecommunication, then through electronic circuit of the present invention, carry out logic transition, " length " in when operation and " short " signal can be transformed into transmitting of closing the door or open the door, the actuator in door receives after remote control command, then carries out relevant logical action.
Two, adopting vibrating sensor 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, the assembly of loudspeaker and transformer 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, the power supply that monitor set, voltage stabilizing, floating charge are integrated, not only all form existing light indication and sound indication while setting standby or the over-voltage and over-current of power supply own.Can also realize the floating charge of science, no matter be 12V or 6V, also or the storage battery of 24V uses this circuit can realize science floating charge.More effectively solved the high and problem that discharge voltage is low of float charge voltage.
(1), principle of stabilized voltage:
It is NPN triode that triode (08 in Fig. 1) is adjusted in voltage stabilizing, adopted the form of penetrating with output, there is very strong feedback, and the voltage of emitter is 0.7V than the few PN junction of base voltage all the time, the independent from voltage of this voltage and collector electrode, once therefore voltage stabilizing is adjusted after the base stage voltage stabilizing of triode (08 in Fig. 1), the emitter voltage that triode (08 in Fig. 1) is adjusted in voltage stabilizing will be stabilized in than on the voltage of the few PN junction of base stage, and this magnitude of voltage be based on meet the standby requirement that sets and fixed magnitude of voltage, such as required voltage is 12V, the base stage of voltage stabilizing adjustment triode (08 in Fig. 1) is exactly 12.7V so.
(2), the explanation of energy lightning protection and anti-overvoltage:
For can needn't power-off at thundery sky, electrical equipment can normally be worked, lightning protection and anti-overvoltage are particularly important.
The reason that forms lightning protection and anti-overvoltage is:
1, be equipped with anti-thunder tube, the withstand voltage numerical value that triode is adjusted in the withstand voltage numeric ratio voltage stabilizing of anti-thunder tube is low, and the stable withstand voltage of lightning protection only has tens volts; and the withstand voltage of voltage stabilizing adjustment triode is several hectovolts, both coordinate, when having thunderbolt; anti-thunder tube preferentially disconnects, and has protected power supply main body circuit.
2, there is overvoltage crowbar (in Fig. 1 06 and 09 form), when having, gush while pressing, overvoltage crowbar is open-minded, again the base stage of voltage stabilizing adjustment triode is carried out to voltage stabilizing, thereby the voltage-limiting protection of generation to output voltage terminal, and the adjustable voltage stabilizing branch road of the voltage ratio of overvoltage crowbar (in Fig. 1 10 and 11 form) height, it is overvoltage protection diode than the number of voltage coarse adjustment diode many three to five, thereby can not open at ordinary times, it is a kind of Status of Backups, secondly, diode in overvoltage crowbar and adjustable voltage stabilizing branch road is all face bonded type diode, than the withstand voltage height of common voltage-stabiliser tube, not fragile.
(3), the explanation of overcurrent protection and Monitoring Performance: this circuit 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 (15 in Fig. 1) increases, after surpassing the emitter and base voltage of overcurrent protection triode (12 in Fig. 1), overcurrent protection triode can form forward conduction, and amplify, voltage stabilizing is adjusted to the base bleeder current of triode (08 in Fig. 1), thereby the output of triode (08 in Fig. 1) is adjusted in sealing voltage stabilizing, the shunting route that triode (08 in Fig. 1) base stage is adjusted in voltage stabilizing is from the emitter of overcurrent protection triode (12 Fig. 1) to collector electrode, and after indication light pipe (13 in Fig. 1) to ground wire, pass through deictic word tablet (14 in Fig. 1) simultaneously.
This circuit 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, and indication light pipe is that string in parallel is on the collector electrode of overcurrent protection triode (12 in Fig. 1) with deictic word tablet; therefore; after overcurrent protection triode is opened, the current collection of overcurrent protection triode is very after high pressure, and indication light pipe sends light indication; deictic word tablet sends sound indication simultaneously, reminds people's equipment that fault has occurred.
After this measure is implemented, another feature of circuit is, when having fault, protection forms automatically, and indication light pipe sends light indication, and deictic word tablet sends sound indication, and fault is when disappear, and automatically recovers.Its reason is that load current is large, and flowing through overcurrent protection resistance (15 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.
(4) explanation that, can science floating charge:
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 in voltage stabilizing; because voltage accurate adjustment resistance can be adjusted the voltage below 0.7V; so adjust easily; realize science floating charge, charge protection resistance (16 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 storage battery (18 in Fig. 1); thereby when having interchange, both can floating charge, can become working power again.
Second, electronic switching tube (17 in Fig. 1) is the effect of battery discharging triode: in the situation that only having direct current, battery tension is standard 12V voltage, but in the situation that alternating current-direct current mixes, storage battery standard float charge voltage is 13.8V, but during battery discharging, Voltage-output is 12V, during charge and discharge, both voltages are inconsistent, if do the isolation between storage battery and voltage output end with diode, when only having direct current, voltage output end can lose the pressure drop of 0.7V, and the present invention has solved this problem well, because electronic switching tube (17 in Fig. 1) is PNP pipe, during its conducting during battery discharging, the pressure drop of electronic switching tube is very little, can ignore, can not produce very large pressure drop, with it, make battery discharging triode, can not lose valuable pressure drop.
The principle that formation discharges and recharges is: the base stage controlled resistor (20 in Fig. 1) of electronic switching tube (17 in Fig. 1) is controlled diode (19 in Fig. 1) with rectification output, there is such principle: when rectification output has voltage, just show now to have alternating current to exist, storage battery should be floating charge phenomenon, electronic switching tube is because be PNP pipe, its base stage has voltage to exist, just can conducting, and collector electrode does not just have Voltage-output.When rectification output no-voltage, electronic switching tube base stage no-voltage, it just forms conducting state, and storage battery starts electric discharge, and collector electrode output voltage is so distinguished two stages of floating charge and battery discharging reliably.
(5), balance diode plays an important role in this circuit, because the standard float charge voltage of storage battery is 13.8V, and operating voltage should be consistent with battery tension, just be unlikely to because have a power failure storage battery and force down equipment is not worked or cisco unity malfunction, therefore increase the number of balance diode, float charge voltage 13.8V is reduced to 12V, while having alternating current, equipment is normally worked, and during storage battery, institute sets 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 guaranteed the correctness of alternating voltage output, and when storage battery power supply, only through pressure drop little discharge and recharge triode, without balance diode, so can not produce pressure drop, therefore guarantee the stable of combined-voltage output.
Four, it is most important point of the present invention that integrates count type logical 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, loudspeaker and transformer group zoarium take out bell signal, then be input in integrates count type logical circuit and carry out logic transition, first output of attribute logical circuit is the signal output part of closing the door, the bit line of gate signal is closed in the formation that connects the integrated circuit of encoding in supporting radiating circuit, send pass gate signal, second output of integrates count type logical circuit is enabling signal output, the bit line that connects the formation enabling signal of the integrated circuit of encoding in supporting transmitting, send enabling signal.Form and close the door and open the door thus.
Counter is the CD4060 of use, it is binary system frequency counter, it possesses 3 features: the one, and built-in oscillator, the 2nd, full static state operation, the 3rd, there are 14 grades of countings, it is comprised of two parts, 14 grades of frequency dividers of a part, output binary system fractional frequency signal, another part is oscillator, by the inverter and the outer meeting resistance electric capacity that include two serial connections, formed, so this integrated circuit can directly be realized the function of frequency division and vibration.
The vibration of counter is by first oscillation resistance (208 in Fig. 2), oscillating capacitance (209 in Fig. 2), second oscillation resistance (210 in Fig. 2) forms, adjust three oscillating elements, the value of Q4 will produce change, corresponding Q value below also can increase progressively, if first counting end Q4 of counter is high 2 seconds, low 2 seconds, second of counter counting end Q5 will be low 4 seconds so, high 4 seconds, and the 3rd counting end Q6 of counter is exactly low 8 seconds, high 8 seconds, increasing progressively with this below, Here it is frequency divider, CD4060 is binary frequency counter.
Therefore when mobile phone has had after bell signal, through the power supply of interface circuit group counter, oscillator produces vibration immediately, counting end Q4 has output at first, now, if the cell-phone bell time is short, all the time be that Q4 produces output signal, be to close gate signal all the time, the bit line that connects the integrated circuit of encoding in supporting transmitting, what now send is to close gate signal, if ring for a long time, at this moment the time has surpassed the time of the 4th counting end Q7 starting of counter, although can produce, close several times gate signal midway, but final generation is enabling signal, the one, because the performance of CD4060 own is binary counter, the 2nd, because the diode (211 in Fig. 2) of external generation failure of oscillation, this diode has been connected to oscillation center point, if the positive pole at diode adds high pressure, failure of oscillation so immediately vibrates, therefore binary system frequency counter carry no longer, once so when having surpassed the starting time of Q7 ring time, what finally obtain is enabling signal, the bit line that connects the integrated circuit of encoding in supporting transmitting, what now send is enabling signal, with binary system frequency counter, do the output of two signals, logic can be not disorderly, 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 for the present invention (call signal for a long time) is opening door operation, by the call signal of short time, it is the signal operation of closing the door, be not easy to occur mistake, because long-time operation has the character of " confirmation ".
And each mobile phone produces bell signal, binary counter starting, all can zero clearing, and this is that this electric capacity is electrodeless electric capacity because connected a zero clearing electric capacity (203 Fig. 2) to clear terminal from power end, reduces and leaks electricity.
Five, cellular phone power supplies is that on the basis of the float charger that is integrated in monitor set and voltage stabilizing, voltage stabilizing forms, and 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 packed 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 float charger that the monitor set of adapted and voltage stabilizing are integrated, there is following outstanding feature: 1, can provide stable operating voltage, there is again monitoring effect, if institute sets the standby fault that occurred, immediately warning, be not only and send light warning, also, with sound warning, active warning user, if fault disappears, warning also disappears immediately, and tracing property is strong.
2, lightning protection and anti-overvoltage capabilities are strong, selected anti-thunder tube is withstand voltage is tens volts, and selected triode withstand voltage be several hectovolts, if there is thunderbolt, gush pressure, the withstand voltage that has surpassed anti-thunder tube, anti-thunder tube preferentially disconnects, and can not make because of thunderbolt power supply damage, and therefore set is for not needing because of thundery sky power-off.
3, anti-overflow is effective, and protection is large, has reduced the heating degree of voltage adjustment triode
4, easy to adjust, realized the science floating charge to storage battery, widely applicable, in the low location of civil power and the high location of civil power, all can normally work.
Two, excellent performance, mobile phone can receive the communication signal of radio net reliably, while receiving signal, the vibrating effect that it sends, excited vibration transducer is reliable, and vibrating sensor is output electrical signals reliably, so remote-control receiver electric property is very good, extremely be suitable for the receiving system opening the door as a kind of phone, open the door sensitive and reliable with the function of closing the door, also can be used as other long-distance remote control simultaneously.
Three, mobile phone is a complete integral body, can make the reception part of signal transducer, also can be used as mobile phone and independently uses, and mobile phone utilance is high.To using mobile phone without secondary operations, can not cause the damage of mobile phone simultaneously.
Four, level of confidentiality is high, because the password figure place of mobile phone is many, than base is more difficult, cracked, and the 2nd, can often change password.
Five, in integrates count type logical circuit, have binary counter can directly realize the function of frequency division and vibration, with wherein two outputs, open the door and close gate signal output, allow open the door with close gate logic can disorder, and be full static state operation, performance is good.
Six, easy for installation, relative section to be put in installation box and formed an integral body, strong security, does not affect attractive in appearance within doors.
Seven, circuit is simple and easy to produce, debug conveniently, is easy to popularize.
