The state of the art of this series products of existing market is the fixed line phone that the user calls out family, takes out the remote signal of opening the door from fixed line phone.Adopt such technical measures, following 3 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, thereby the expense that phone opens the door is higher.The 3rd, voice suggestion is arranged more, outwards passed on and brought out the crime signal.For this reason, the designer had once applied for patent, and the enforcement of this patent will make up the deficiency of existing product.But it is supporting with it that this patent need to a kind ofly receive the controller of distant signal, and this controller should meet following requirement:
1, want to receive remote signal of notifying from a phone call on electric property, can change the signal of notifying from a phone call into open the door the signal of telecommunication simultaneously.For not affecting the aesthetic feeling of the original decoration of family, so also have following requirement
2, attractive in appearance, independence is strong, becomes independent parts.
3, be convenient to place flexibly, easily supporting with the control board that coordinates.
In the automated production of present door industry, there is no satisfactory controller.Do not have a kind of transducer directly to meet above-mentioned 3 requirements without innovation yet.
Realize that this technical scheme mainly contains following difficult point:
1, the kind of pickoff is a lot, all to convert a kind of physical quantity to a kind of good device of ultra-weak electronic signal, but in the middle of numerous kinds, but not having a kind of is directly the remote call signal that receives, to change the device of signal of telecommunication kind into.
2, cell phone and fixedly base can receive easily remote call signal from communication network, but they all can not be used as controller because they all can not be directly outside output electrical signals.Want outside output signal, all must again process by traditional method, the relevant point in is internally drawn signal, but this do the integrality that can affect complete machine, especially easily cause the damage of mobile phone.
So, the effective ways of dealing with problems are, form a kind of new controller with existing device, with the first part that can receive the new controller of remote communication device such as cell phone composition, and with another kind of transducer as the new compound sensor of the present invention second the part, namely second portion is converted into remote signal " original " signal of output more again.But this forms new compound sensor, following specific requirement is arranged again:
3, adopt the combination of which type of Communication Equipment and which type of senser element, just can make the front part that receives signal and the rear part of output signal realize the coupling of signal transmission science.Signal is lost little relatively, thereby makes the electric property of new compound sensor the most reliable and stable.
4, adopt the new transducer of what carrier combinations two parts, reliable, integral body is relatively attractive in appearance, small volume.
5, mobile phone is of a great variety, produces difficulty in many-side.One of, the type disunity also is subject to operator's operating habit simultaneously, and the impact of switch, some rings are on-off states, have plenty of continuous state, some signals are strong, a little less than some signals, there is what kind of circuit to process, just can make " primary signal " of taking out from mobile phone to become reliable remote signal? two, the jack disunity, take out the signal of calling, not retrained by Multiple Type socket model with what kind of method, easily produce; Three because the present invention is that supporting product is security personnel's equipment classes, with the present invention's distance of having living space, could what kind of circuit after the present invention received signal, also must adopt wireless remotecontrol to carry out secondary contact be to actuator, so it is used and just can make wireless remotecontrol radiating circuit reliable operation?
6, mobile phone will be in continuous duty, needs to solve the maintenance of battery on mobile phone, becomes one of difficulty; Two be if adopt external power supply to replace the mobile phone accumulation pond, allow the mobile phone long-term work, but now a lot of mobile phones are all to adopt a jack, this jack is namely the external charge jack, it is again the insert earphone jack, and will from socket of mobile phone draw simultaneously be namely input be output two groups of signals, be difficult to carry out.
Relate in addition the aspect problems such as cost.
Summary of the invention
The objective of the invention is to design a kind of new combined type trans, be mainly used in the automated production of supporting door industry, the one, realize that phone opens the door, to the patent that the designer applies for, do further to replenish.Two are to provide a kind of transducer kind of excellence, for the outstanding product of developing door industry class provides larger space.
Concrete measure of the present invention is:
1.Multi-function sensor is whole by the network receiver, the vibration damping thing, and mobile phone equivalence external power, electronic switching circuit, radio transmitter circuit forms jointly.
Wherein: network receiver integral body is made of jointly mobile phone, vibrating sensor, and vibrating sensor is fixed on mobile phone, draws output line at the lead-in wire pile crown of vibrating sensor as signal with wire bonds; The vibration damping thing is fixed on the whole outer surface of network receiver.
Electronic switching circuit is: with having connected the base stage of a NPN triode after the series connection of resistance of vibrating sensor output lead-out wire process, the grounded emitter line of this triode, the base stage that has connected this NPN triode with an end of a resistance, the other end earth connection of this resistance; The connected rear base stage that connects a PNP triode of another resistance of the collector electrode of this NPN triode, the emitter of PNP triode has connected 12 volts of power supplys, the emitter that has connected the PNP pipe with an end of another resistance, the other end of this resistance have connected the base stage of PNP pipe; The base stage that has been connected the NPN pipe after the collector electrode that has connected the PNP pipe with a utmost point of an electric capacity, resistance of the another extreme series connection of this electric capacity and diode cathode; Another utmost point of this electric capacity has also connected an end of another resistance, the other end ground connection of this resistance; This PNP transistor collector has connected the power input of wireless remotecontrol radiating circuit.
2, vibrating sensor is piezoelectric ceramic piece, is to draw output line from two kinds of utmost points of piezoelectric ceramic piece.
3, mobile phone equivalence external power, comprised two kinds of Voltage-outputs, and the firstth, mobile phone required voltage, the secondth, electronic switch operating voltage.
4, the feedback capacity in electronic switching circuit is in series by two electrochemical capacitors, and wherein two electric capacity negative pole ends connect together.
The relevance of above measure further is explained as follows:
1, the principle as the functional device of a kind of phone start is that what at first to need is the function that can receive the phone calling room outside, after the calling of phone, just can send the instruction of opening the door outside it receives the room.In the present invention, mobile phone Main Function used receives the use of mobile phone outside the room (" key " mobile phone) calling exactly.Therefore in the present invention, measure is that the mobile phone of innovation must have two kinds of functions, and the first function is the calling that can receive the phone room outside, the second function be will calling acoustical signal again be converted into the signal of telecommunication of output.
2, mobile phone itself has receiving function, and the acoustical signal of calling out is converted into output electrical signals, and the present invention has adopted the vibrating sensor conversion.Concrete measure is that vibrating sensor is fixed on mobile phone, after mobile phone has had call signal, will become a kind of vibration source, and at this moment vibrating sensor will be converted into the signal of telecommunication to the acoustic vibration signal and outwards export.This signal of telecommunication can be introduced in control circuit.Therefore mobile phone is through after such processing, and its science is that common mobile phone can realize becoming a kind of can the reception and the special-purpose sensing controler of exportable remote control, and this is one.It two is to solve only jack of mobile phone, and the present invention needs the contradiction of external power supply and two jacks that take out call signal, and it three is not to be subjected to mobile phone model different, and causes the different difficulty of mobile phone socket mechanical form.
3, piezoelectric ceramic piece is good microphone device, and when the two poles of the earth at them added audio telecom, this sheet can sounding.Test shows: also can be with its inverting function as a kind of vibrating sensor.That is to say that when adding vibration signal at their the two poles of the earth, the faint signal of telecommunication can be exported in the two poles of the earth of potsherd.If it is fixed on mobile phone, mobile phone is received signal because sound and vibration are arranged, so just can become a kind of vibration source, allows the two poles of the earth of piezoelectric ceramic piece export sensing telecommunications.Potsherd is thin, and area is less not fragile, and is easily fixing.In in vibrating sensor, specification requirement more according to the invention.And present following benefit, and the one, when vibration is converted into electrical, reliable.The 2nd, it is convenient to implement, as long as with glue, piezoelectric ceramic piece is glued on mobile phone, does not destroy mobile phone integral body fully.The 3rd, anti-doing resists by force, must directly beat piezoelectric ceramic piece and just may respond.If wrap the vibration damping thing outside the whole bag of mobile phone after, can further stop to disturb.
4, electronic switching circuit has played important function in the present invention, stresses below also must doing:
(1), meaning: one of after the present invention receives bell signal, it not final purpose, final purpose is to remove to promote the wireless remotecontrol radiating circuit with bell signal, make it to send the initiating signal of wireless remotecontrol emission, supporting performer is moved after receiving remote signal, (being fruitful as the inventor is antitheft door, to allow the power set that open the door of door start) so, how bell signal reliably promotes radio transmitter circuit, it is an important technology key, its reason is because mobile phone is of a great variety, some rings are on-off states, has plenty of continuous state, during some rings, signal is strong, a little less than some signals, if do not have a kind of good circuit to carry out aftertreatment, be difficult to guarantee the reliability of product, and adaptability is widely arranged.Two be electronic switching circuit because the present invention has had aftertreatment, therefore the present invention's mobile phone used is not limited by the requirement of mobile phone model can, extensively and easily coordinate, this is one; It two is that the present invention receives to adopt after signal radio transmission and execution unit to contact, and any execution unit can add receiving system and realize mating with the present invention, so can also extensively and easily join by supporting execution unit.
(2), the action principle of this circuit: after mobile phone has been exported bell signal, be sent to by NPN and PNP form the pipe amplifying circuit is amplified, owing to closing amplification through the direct lotus root of two-stage, has very large amplification quantity, adopted regenerative circuit, so the amplification quantity multiplication is when having the signal input in addition, be enough to make second level PNP pipe output saturation, thereby promote radio transmitter work.Here should illustrate following some:
The first point, adopt that NPN and PNP constitute jointly to managing the amplification form, following meaning is arranged, one of, amplification quantity is large, two, the PNP pipe become saturated after, the loss of voltage that produces is little, three, can easily bell signal be changed into the electronic switch form of controlling radio transmitter circuit.Four, formed electronic switch volume urine is in miniaturization.
Second point: in the electronic switching circuit that pipe is formed, anti-remaining resistance, namely that the resistance that connects between PNP pipe emitter and base stage has played important function in circuit, its effect is when NPN pipe no signal, the thorough no-voltage of the output of switch, output for the through engineering approaches that electronic switch uses, has been created essential condition without any remaining electricity.
Thirdly, why to add positive feedback between two pipes, one of reason be except because strengthening amplification quantity, also having its important meaning is to change the cell-phone bell signal of interrupted class into a kind of continuous signal, greatly enlarged the kind of mobile phone, made the mobile phone applicable surface wider.Its reason is to produce the process of positive feedback, and no matter the signal of mobile phone is interrupted, or continuously, is weak signal or strong signal, all become irrelevant thing, and positive feedback branch has played leading role.Two reasons be, supporting security personnel's series products, it produces radio secondary emission, and is different from common remote control circuit because its coding integrated circuit is polylith, non-monolithic, this just needs emission have the certain hour process, rather than very short transient process.This required time course, only having with feedback branch provides just the most reliable.
The 4th point: why feedback capacity adopts electrodeless reason to be, the electrodeless electric capacity electric leakage is little, under being used at feedback circuit, circuit is more stable, after having adopted measure 4, have the electrochemical capacitor of the utmost point to become electrodeless, its leakage coefficient improves greatly, and this is very important for the electronic switch circuit that positive feedback is arranged.
the 5th point, the reason why feedback in the two-stage amplifying circuit will add resistance and diode and electric capacity institute series circuit is, the benefit that has added electric capacity is that feedback is along with capacitor charging completely will finish at last, thereby after bell signal disappears and feeds back end, the control that the PNP pipe will return to load again becomes open-circuit condition, this is one, it two is to form the Capacitance derivative charge constant with the resistance of connecting, this time is led the time that has determined positive feedback, it is also the time that electronic switch is opened, thereby can reliably the breakpoint bell signal be become transmitting of length arbitrarily.With the time course that guarantees that emission is required.The reason that has added diode is, during base stage when the input of cell-phone bell signal at the first pipe, do not produce the too much loss of signal.
Following outstanding advantages is arranged after the invention process:
1, mobile phone can receive the communication signal of radio net reliably, and after receiving signal, through the conversion of electroceramics sheet, the signal of telecommunication of output is reliable.So electric property of the present invention is very good, extremely be suitable for the receiving system that opens the door as a kind of phone, also can be used as other long-distance remote control simultaneously.
2, mobile phone is a complete integral body, can make the reception part of signal transducer, can be used as also all that mobile phone independently uses, and the mobile phone utilance is high.Simultaneously, to using machine without secondary operations, can not cause the damage of mobile phone.
3, mobile phone adopts the wireless radio transmission network to receive signal, so, place the constraint (will be subject to the lead-in wire interface constraints of telephone wire as adopting base) that is not subjected to environment, do not affect attractive in appearance within doors, do not know for its people yet, with inventor's achievement adapted, all bring benefit to maintaining secrecy.
4, practical, only manage mobile phone model of a great variety, but all be suitable for, the one, the measure in the present invention can be taken out the call signal of disposable type mobile phone, the 2nd, after through electronic switch, " original " bell signal of mobile phone taking-up being processed, performance increases, and nearly all mobile phone can be with in the present invention.
5, the operator user makes, and the user is all right to the various operations of mobile phone, does not change habits and customs, does not produce the maintenance that mobile phone changes battery.
6, level of confidentiality is high, and cell phone password is 11, carries guessing right and separates difficulty.
7, easily batch production.
