The effect of clamper triode (105 in Fig. 2) is when the cell-phone bell time is long, be that integrating resistor (103 in Fig. 2) has been less than the time constant of cell-phone bell with the formed time constant of integrating capacitor (104 in Fig. 2), 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. 2) and the formed time constant of integrating capacitor (104 in Fig. 2), 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, in technical scheme 1, implemented wireless remote control transmitting and adopted wireless remotecontrol launch scenario, the distance of radio controlled transmitting has much relations with size when same circuit.Because it has a great impact with reliability the stable of radio ttransmitter and receiver.In the present invention, the specific geometry of copper foil antenna is the handstand form of English capitalization U, article two, the Copper Foil of vertical parallel top connects with arc Copper Foil kissing, copper foil antenna width is 2mm, the Copper Foil length of two vertical parallel in left and right is 30mm, article two, the spacing of vertical parallel Copper Foil is 20mm, the height that kiss connects the arc Copper Foil of two vertical parallel Copper Foils is 4.5mm, strict formulation, so can realize well and mating between transmitting and reception, and external antenna is sucker antenna, and between copper foil antenna, there is coupling capacitor, sucker antenna is fixed on outside box, be conducive to improve transmitting sensitivity, according to result of the test, the present invention proposes this measure, intrinsic good effect.
Five, power supply is the basis of all electronic products, and its direct relation the quality of properties of product, and therefore spy does following explanation to power supply:
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 circuit has two kinds of functions of overcurrent protection and monitoring.
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 (9 in Fig. 1) increases, after surpassing the emitter and base voltage across poles of overcurrent protection triode (12 in Fig. 1), this overcurrent protection triode can form forward conduction, and amplify, and the base bleeder current to voltage adjustment triode, thereby sealing voltage is adjusted the output of triode (8 in Fig. 1), the shunting route of base stage is from the emitter of overcurrent protection triode (12 Fig. 1) to collector electrode, and after overcurrent protection monitoring indicator light (13 in Fig. 1), arrive ground wire.
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; string is bright at the overcurrent protection monitoring indicator light (13 in Fig. 1) of overcurrent protection triode (12 in Fig. 1), luminous for people's observation.
After this measure is implemented, another feature of circuit is, when having fault, protection forms automatically, and overcurrent protection monitoring indicator light (13 in Fig. 1) is luminous, and fault is when disappear, and 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 circuit 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, rather than 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, saved 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 circuit can be formed on the reason of working under very wide civil power:
Due to this circuit, not to be afraid of input voltage too high, so input voltage can be established and adjusted higherly when design, when 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 storage 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 each voltage stabilizing value of diode, there is reliable consistency, can accomplish more accurately and adjust, and resistance can be 0.7 with interior 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 storage battery (18 in Fig. 1), thereby when having interchange, both can floating charge, can become working power again.
The second, battery tension is standard 12V voltage, but in the situation that alternating current-direct current mixes, storage battery standard float charge voltage is 13.6V, but during battery discharging, Voltage-output is 12V, during 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, during its conducting during battery discharging, the pressure drop of discharge diode is very little, can ignore, and 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 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, storage battery should be floating charge phenomenon, discharge diode is because be PNP pipe, its base stage has voltage to exist, and can conducting, and collector 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 storage battery starts electric discharge, and collector 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 storage battery is 13.6V, 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 13.6V is reduced to 12V left and right, 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 the little discharge diode of pressure drop, without balance diode, so can not produce pressure drop, therefore guarantee the stable of combined-voltage output.
Six, mobile phone coupling power supply is that voltage stabilizing forms on the basis of being with the float charger showing, 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.
Seven, mobile phone sensing being received to body packs in the vibration damping bag of being made by the textile such as cotton, numb, allowing mobile phone sensing receive body can not damage because of shock, mobile phone sensing receives after body packs vibration damping bag into and 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.
The float charger that the band of two, joining shows has following benefit: the floating current source that 1, band shows; stable voltage can be provided; again to the standby monitoring effect of having played of set; if institute sets standby breaking down, source current is increased, overcurrent protection monitoring indicator light sends light warning immediately; and when being fault-free at ordinary times; can not produce warning, if supporting security personnel's product has avoided the security personnel that do not know because of power failure blank.
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, surpassed 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, and protection is large, has reduced the heating degree of voltage adjustment triode.
4, adaptive faculty is strong, in the place that civil power is high, can not damage, and in the place that civil power is low, also can normally work.
5, easy to adjust, realized the science floating charge to storage battery, there is overcurrent protection ability simultaneously.Applicability is strong, easy-to-use supporting with other electronic product, strengthens the performance of electronic product.
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, practical, although mobile phone model is of a great variety, adopt the number of winning the confidence of the distinctive method of the present invention, be all suitable for, there is very strong Practical significance.With this method mobile phone, be a complete integral body, also can be used as mobile phone and independently use, mobile phone utilance is high, to using mobile phone without secondary operations, can not cause the damage of mobile phone simultaneously.
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, mobile phone no longer needs to change battery, guarantees that the service behaviour of mobile phone is good, can not damage.
Seven, 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.
Eight, the raising of sensitivity makes transmitting realize better cooperation with reception, launches more reliable.
Nine, relative section is put into box and formed an integral body, strong security.

Embodiment
Fig. 1,2,3,4,5,6 has described the concrete a kind of mode implemented of the present invention jointly, and concrete operations are as follows:
One, implement mobile phone sensing and receive body:

Two, implement bielectron switching logic circuit.
1, welding as shown in Figure 2.
2, cell-phone bell holding wire is connected to integrating resistor and isolation resistance.
3, debugging: the time constant of adjusting the input that opens the door adjusts the size of integrating capacitor and integrating resistor, making it effect is when ring is short signal, to only have the gate signal of closing output, and when ring is long signal, finally only have enabling signal output.
Three, implement wireless remotecontrol radiating circuit:
1, wireless remotecontrol radiating circuit welds by Fig. 4, and the size of copper foil antenna is set on request.
2, realize being connected of two function logic line units and wireless remotecontrol radiating circuit: the gate signal of checking on output is connected in coding integrated circuit and produces on the control bit line of the function of closing the door, enabling signal output is connected in coding integrated circuit and is produced on the control bit line of door opening function.
Four, as Fig. 1 implements the float charger that band shows: selected triode: voltage is adjusted triode, overcurrent protection triode and discharge diode and all selected high back-pressure large power triode.Anti-thunder tube selects puncture voltage parameter lower than the model of triode back-pressure value.
1, by Fig. 1, weld, the diode in voltage-stabilizing protection unit is wanted many three to five of diode in the adjustable voltage stabilizing branch road of specific output, and to export the voltage of adjustable voltage stabilizing branch road high for the voltage ratio of voltage-stabilizing protection unit.
2, adjust power supply output valve.Adjust the number of voltage coarse adjustment diode, can adjust on a large scale, 0.7 volt of range of voltages of each diode is adjusted, voltage accurate adjustment resistance is done 0,7 volt with interior voltage adjustment, its rule is that more multi-output voltages is higher for the number of voltage coarse adjustment diode, or the resistance of voltage accurate adjustment resistance is larger, output voltage is higher, otherwise lower.
3, adjust overvoltage protection parameter.The transformer primary side that breaks, is connected on source of stable pressure output with oscillographic, by the direct voltages click rectifier terminal of 100 volts; oscilloscope display output; the amplitude that this voltage rises is limited, otherwise should adjust the voltage stabilizing value of voltage-stabilizing protection unit, increases the number of diode in voltage-stabilizing protection unit etc.
