Description
Technical field
The invention belongs to the program control technology field.
Background technology
With the remote opening door operation of phone realization door, be a kind of fashion of social popularity.The state of the art person of being to use of this series products of existing market calls out the fixed line phone that is placed in the family, by voice suggestion, inputs the password of secondary enabling signal again.Adopt such technical measures, following 2 deficiencies are arranged, the one, the phone level of confidentiality figure place of opening the door is not high enough; The 2nd, phone has the off-hook program, and the expense that phone opens the door is higher, with often voice suggestion being arranged, the information of bringing out crime is arranged.For this reason, the designer had once applied for a patent, and the enforcement of this patent will remedy the deficiencies in the prior art.But this patent needs a kind of receiver supporting with it, and this receiver should meet following requirement:
1, wanting to receive the signal that long distance network is notified from a phone call in electric property, can be the signal of telecommunication that opens the door with the signal transition of notifying from a phone call simultaneously.For not influencing the aesthetic feeling of the original decoration of family, so also have following requirement.
2, attractive in appearance, independence is strong, becomes independent parts, in order to supporting.
3, be convenient to place flexibly.
In the present automated production of door industry, there is not satisfactory receiver.Consult existing pickoff spare, also do not have a kind of transducer can directly meet above-mentioned 3 requirements and make the sensing adapter.
Realize that this technical scheme requires to mainly contain following difficult point:
1, the kind of moment sensor is a lot, can both convert a kind of physical quantity to electronic circuit required initiating signal.But in numerous kinds, but the neither one kind has directly the network that receives is notified from a phone call signal at a distance, changes the required function that plays dynamic control signal of electronic circuit into.
2, present senior product often has (maybe must have) wireless link link, also finds to have following difficult point in research process:
Test shows that the distance of emission is that sensitivity one is to have a significant impact with weather, and fair weather is then effective, and bad weather is poor effect then; The 2nd, with the environment in place very big influence is arranged, local effective as in spaciousness, and just special poor in the many places of cover material.Emission of the present invention and receive between be not the ground of spaciousness, and between a lot of cover materials are arranged, as furniture etc.If put receive body more hiddenly again, environment can be more complicated.So the present invention has very high requirement to the requirement of sensitivity, if with traditional method for designing, then be difficult to satisfy.Its reason is, therefore the position that a lot of products can the Iterim Change emission can both receive between the two.And in a single day emission of the present invention and receiving position are determined, and run into bad weather, and performance will be challenged, and therefore should have what kind of measure could satisfy designing requirement.
3, cell phone can receive remote call signal easily from communication network, but it need change the maintenance of battery, and this is one.It two is that good electronic product needs a kind of good stabilized voltage power supply supporting with it.Because the present invention is a kind of special application product, because its main effect is to realize that phone opens the door, it should be in a kind of armed state at any time, namely is to be in normal operating state at any time, otherwise can not opens the door, directly influence life.Obviously supporting with it with the power supply design of ordinary electrical home appliance is to be difficult to reach such purpose, thereby just also can operate as normal during the no alternating current of needs, so this power supply must be furnished with storage battery, just must must carry out floating charge to it and be furnished with storage battery.But by traditional method for designing, the contradiction in the time of can not solving storage battery floating charge and regular picture.Its reason is, if battery tension is nominally 12 volts, and its float charge voltage should be between 13,2 to 13,8 volts science.If according to the method for designing of a lot of products, allow the direct floating cell of alternating current, and powered to work system again by storage battery, like this whole system with long-term work on the voltage of floating charge, exceed about 1,4 volt for 12 volts than normal voltage, high if distributor requires, then be difficult to accept.If it is simply that the step-down of storage battery float charge voltage is low to normal 12 volts, again to system's power supply of joining, produce new contradiction again, because storage battery is after discharge work a period of time, drop to 12 volts with very fast by higher float charge voltage, therefore when floating charge originally correct voltage falls again with low 1,4 volt, it is undesired to have influenced supporting electronic circuit performance.Thereby now a lot of products can't address this problem.Can only be connected on bridge-type output to storage battery simply, to the storage battery floating charge, though solved the correctness of institute's distributor operating voltage like this, can't consider the science of floating charge with bridge rectifier at all.With seriously easily influencing into the life-span of storage battery, to much requiring the high product of auxiliary products obviously inapplicable.

The relevance of above measure further is explained as follows:
One, the principle of the functional device that opens the door as a kind of phone is, what at first need is to receive the function that phone is called out outside the room, after the calling of phone, just can send the instruction of opening the door outside it receives the room.Mainly to act on be the usefulness that do to receive mobile phone (" key " mobile phone) calling outside the room to used mobile phone among the present invention.Because when mobile phone was called out outside the room, receiver ring of the present invention rang within doors, and signal is drawn by loudspeaker, is reliable so receive signal.
Two, in technical scheme 1, implemented the wireless remotecontrol emission, important meaning is arranged, test shows, the distance of emission is that sensitivity and weather have a significant impact, and the present invention is very high to the requirement of sensitivity, if with traditional method for designing, designing requirement of the present invention is satisfied in very difficult assurance, its reason is, position and distance that general emission can the Iterim Change emission can receive that signal just could as long as can satisfy reception at that time.And emission of the present invention and receiving position are definite, can not be because of the interim change of the difference of weather (can influence like that normal life is breezy is used to) in use, in case when bad weather, just be difficult to guarantee the performance of product, so the essential measures necessary that increases.And the present invention can largely improve sensitivity, and namely being increases external antenna to improve sensitivity, but will increase external antenna, must do certain processing to radiating circuit, so just can reach best effect.The first must increase an electric capacity, isolates with antenna.It two is that this electric capacity must be welded in a special position, this position must be to be an end of high-frequency emission pipe collector at the antenna Copper Foil output at printed panel, and can not be in other place, this external antenna can the sucker antenna, can obtain good reception with this antenna.
If three only use the signal mobile phone as receiving network signal, but there is not excellent mobile phone to safeguard power supply, can't become the product that can receive on a kind of engineering, more can not become the good product of a kind of excellent performance, because mobile phone needs normal battery to safeguard, if the employing Alternating Current Power Supply, also essential will be under multiple condition of severe can operate as normal, so the power supply of safeguarding of mobile phone becomes a key component of the present invention.
Four, power supply is an emphasis of the present invention, is directly connected to performance of the present invention.The specific explanations of circuit is as follows:
1, measure meaning summation:
Circuit of the present invention can become three parts from the functional perspective classification, first's output power supply, and general output voltage is nominal battery voltage; Its electric second portion output float charger, this power supply is the required science voltage of floating charge, and is higher about 1,4 volt than nominal battery voltage usually.Third part is electronic switch, and they mainly are the automatic control of implementing storage battery floating charge and discharge, simultaneously the valuable pressure drop of can not lose storage battery basically when discharge.
2, the explanation of first's working power:
This part is served as by Alternating Current Power Supply circuit of three-terminal voltage-stabilizing integrated and peripheral element.It exports three tunnel reason, and one the tunnel is that three ends are protected, and to the output clamper, output end voltage is higher than about PN joint of input at most.Two circuit compensate three end integrated circuit output values, because the output of three end integrated circuits has had isolating diode, have reduced by a PN joint, press so three end integrated circuits must improve a PN economize on electricity at output.Three-circuit is isolating diode, and it mainly acts on and is, when no city during by storage battery power supply, by storage battery power supply, because electronic switch is open-minded, must isolate three end integrated circuits, do not produce and flow to the shunting here of three end integrated circuits, this is to saving the electric current of storage battery preciousness, and is beneficial.This part has formed such operation principle: when civil power, this part work is because these part three end integrated circuits have carried out the compensation of voltage stabilizing value, so exported the operating voltage of nominal, by storage battery power supply the time, this part is not outwards powered and and external isolation.
It should be noted that if nominal battery voltage and floating voltage difference are excessive can increase the number of diode at the earth terminal of this three ends integrated circuit, perhaps string is gone up resistance again.Its relation is, if more than PN joint of difference then string is gone up diode, as difference a PN joint with next string on resistance, at this moment can mainly regulate the operational voltage value that this resistance then can be transferred requiredly.Adopting another benefit of diode is that the diode nominal value is strong, also favourable batch process.
3, the explanation of second portion floating charge part:
This part is served as by second three end integrated circuit (669) and peripheral element.Because float charge voltage is higher than nominal battery voltage 1, about 4 volts, to export voltage inconsistent so adjust output voltage stabilizing value and first three end integrated circuit of three end integrated circuits of this piece.At this moment can adjust the ratio of its peripheral element two resistance (670,671) implements.Its rule is that earth terminal and ground wire series resistance 14 resistances are more big, and then output voltage is more high, and can obtain float charge voltage accurately.
The adjustment of first's working power voltage simultaneously is the same, if output and the nominal battery voltage of three end integrated circuits are excessive, can increase the number of diode at the earth terminal of this three ends integrated circuit, and perhaps string is gone up resistance again.Its relation is, if more than PN joint of difference then string is gone up diode, as difference a PN joint with next string on resistance, at this moment can mainly regulate the operational voltage value that this resistance then can be transferred requiredly.Adopting another benefit of diode is that the diode nominal value is strong, also favourable batch process.
4, third part electronic switch explanation:
When the bridge-type output voltage, having shown has alternating current, storage battery to should be the floating charge stage at this moment, at this moment bridge-type voltage is through the transmission of control diode (676), make the base stage of switching tube PNP pipe that voltage be arranged, PNP pipe can conducting and become closed state, the collector electrode no-output.The present invention of this stage has only the output of first three end integrated circuit.When bridge-type output no-voltage, from the additional control voltage of bridge rectifier, the electronic switch that the PNP pipe constitutes does not become opening state to PNP pipe base stage.Output of the present invention then comes from the battery discharging power supply.Because above-mentioned reason and principle so electronic switching transistor just can be distinguished the situation that civil power has or not electricity reliably, and are switched two stages of floating charge and battery discharging automatically.Should point out heavily that this pipe PNP pipe is a state automatic control switch pipe not only, and very the more important is arranged, when storage battery was in discharge condition, this pipe was in saturation condition, and the voltage that falls is very low, can not lose the most valuable pressure drop of storage battery basically.
Five, the voltage transitions adaptation is to export emitter follower of 12 volts of terminations as the mobile phone voltage-reg-ulator tube from power supply, because the emitter follower base stage has 5 volts of voltage-stabiliser tube voltage stabilizings, so the output of emitter follower is made balance with diode again than 5 volts low PN utmost points, reaches 3.6 volts requirement.
Following outstanding advantage is arranged after the invention process:
One, mobile phone can receive the signal of wireless communication networks reliably, and anti-interference strong, and this is because no matter be that extraneous acoustic jamming or electrical interference all can not make sound horn, produces the malfunction signal.Very be suitable as the receiving system that a kind of phone opens the door.
Two, mobile phone receives signal by the wireless radio transmission network, so, place the constraint (will be subjected to the lead-in wire interface constraints of telephone wire as adopting base) that is not subjected to environment, do not influence attractive in appearancely within doors, do not know for its people, to the secret benefit of all bringing yet.
Three, strong security, the one, cell phone password is 11, the 2nd, can change at any time.
Four, can realize coupling well between emission and the reception, promote distance between the two greatly.Radio transmission and receive between good effect is arranged, receiving unit can be put more hiddenly, and laying of being in a little brought more selection, the while also can be to the secret space that provides a little be provided.
Five, because the present invention has adopted excellent power supply adapted with it, promoted the performance of integral body of the present invention comprehensively, embodied in the following areas: (1), city exchange when electricity is arranged, and voltage regulation performance is good.Reason one is all advantages with modern outstanding three end integrated circuits, and voltage regulation result is good, and defencive function is good.
(2), when alternating current is arranged, what storage battery remained is float charge voltage, satisfies the requirement of storage battery floating charge, implemented best science and safeguarded that storage battery is not fragile, the life-span is long, this may produce the blank period of security personnel for protector section product particular importance because battery damages.
(3), during at no city alternating current and by storage battery power supply, storage battery is mainly confessed be nominal voltage as about 12 volts, do not influence the required performance of system.
(4), when storage battery is in discharge regime, switching tube is saturation condition, the droop loss most valuable to storage battery is very little.(when storage battery normally discharged, because the faint variation of voltage has all shown discharge scenario, pressure drop was most valuable).
(5), circuit is uncomplicated, debugging is simple.
