Description

A kind of security personnel's receiving-transmitting device that contains electronic switch

Technical field

The invention belongs to networking technology area.

Background technology

With the remote opening door operation of phone realization door, it is a kind of upsurge 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 of family, takes out the remote signal of opening the door in the voice suggestion of the reception fixed line phone from family.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, thereby the expense that phone opens the door is higher.For this reason, the designer had once applied for a patent, and the enforcement of this patent will remedy the deficiency of existing product.But it is supporting with it that this patent need a kind ofly receive the transducer of distant signal, and this transducer also should not influence the aesthetic feeling of the original decoration of family except function should meet following requirement, meet following requirement:

1, wanting to receive remote signal of notifying 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.

2, attractive in appearance, independence is strong, becomes independent parts.

3, be convenient to place flexibly.

In the present automated production of door industry, also there is not a kind of transducer directly to meet above-mentioned 3 requirements.

Realize that this technical scheme mainly contains following difficult point:

1, the kind of pickoff is a lot, it all is the good device that can convert a kind of physical quantity to a kind of ultra-weak electronic signal, but in the middle of numerous kinds, but not having a kind of is to change the device of the signal of telecommunication kind of opening the door into directly the remote call signal that receives.

2, cell phone and fixedly base can from communication network, receive remote call signal easily, but they are not a kind of transducers because they all can not directly outwards export the signal of telecommunication.Want outside output signal, all must process again by traditional method, inconvenient relevant point in is internally drawn signal, but this do and can influence the integrality of complete machine, and cause the damage of mobile phone especially easily.

So, the best effective ways that solve existing issue are to form first among the present invention partly with receiving remote communication device cell phone, with another kind of senser element as second among the present invention partly, the new composite receiver of the common composition of two parts, after from communication network, receiving remote call signal, again remote signal is converted into output signal.But this has following specific requirement again to the present invention:

1, adopts the combination of which type of Communication Equipment and which type of senser element, just can make preceding part of the present invention and the rear section 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.

2, adopt two parts of the new compound sensor of what carrier combinations, dependable performance, integral body are attractive in appearance relatively, volume is less.

3, owing to mobile phone model and in many styles, the jack disunity will take out the signal of calling, is difficult to implement with unified plug wire mode method.

4, mobile phone will be in continuous duty, and mobile phone need be changed battery, in case a little less than the electricity, it is undesired to work, so mobile phone can not keep the state that can receive at any time, how to overcome.

5, because the starting of reporting to the police is the key element of alarm, whether reliably he directly relate to starting, or malfunction is not arranged.Show after deliberation, address this problem, must work hard simultaneously aspect machinery and two in the circuit, cooperatively interact, the effect that can obtain, but to use what kind of mechanical structure, and what kind of circuit of joining be only best processing method, this also is an important topic that is worth research.

6, present senior product often has (maybe must have) wireless link link, and the radio transmission product mainly is to adopt the solid size radiating circuit emission that coding is arranged now, this is feasible for general household electrical appliances, but can not satisfy the requirement of precision for the product of higher gears, not only because social upward wireless remotecontrol has been widely used in various fields now, as the lock of locking of automobile burglar, all will use remote control, and these all become wide interference source.Also there is artificial instrument interference and cracks.The problem of disturbing for solving if adopt high-grade coding integrated circuit, relates to serial problems such as cost again, therefore which type of encodes to realize thoroughly to stop all interference in the society with, and reaches cost low purpose again, also becomes a difficult problem.

Because the existence of above-mentioned difficult point, so there is not such product to exist now.

Summary of the invention

The objective of the invention is to design a kind of transducer of compound character newly, be mainly used in the automated production of supporting door industry, the one, to the patent that the designer applies for, do further to replenish.Two provide a kind of transducer kind of excellence, for the outstanding product of developing door industry class provides bigger space.

Concrete measure of the present invention is:

1, the family expenses receiving-transmitting device that contains electronic switch is by remote-control receiver, the timing feedback circuit, and many yards emissions of diode OR gate formula, the vibration damping thing is formed jointly.

Remote-control receiver is made of jointly mobile phone, vibrating sensor, and vibrating sensor is fixed on the mobile phone, draws output line at the lead-in wire pile crown of vibrating sensor as signal with wire bonds.

The timing feedback circuit: be connected on the base stage of first triode behind resistance of the output lead of vibrating sensor series connection, the grounded emitter line of this triode, collector electrode has connect two-way, one of be to join with power supply after having connect a resistance; Two be connect a resistance an end, another termination of this resistance the base stage of second triode.

Second transistor collector connect two-way, one of be to have connected to be connected on power supply behind the resistance; Two are ends that connect a feedback capacity, the other end of this feedback capacity has been connected and has been connected on the base stage of first triode behind a diode and the resistance, also connects a resistance between this end of this feedback capacity and the ground.

Second transistor collector outwards exported and drawn holding wire, connected radiating circuit then.

Many yards emissions of diode OR gate formula: it is corresponding with it to connect a plurality of inverters respectively with second programme controlled a plurality of output, the chip select end that connects polylith coding integrated circuit with the output of each inverter respectively, be connected to the positive pole of a diode with the output of polylith coding integrated circuit, the negative pole of a plurality of diodes links together, after a resistance series connection, be connected the base stage of modulation three utmost points in the transmitter unit.

The vibration damping thing is fixed on remotely monitored sensor receiver outer surface.

Connect supporting power output socket mouth and cell-phone charging socket with mobile phone external charge output data line.

Remote-control receiver, one of supporting power supply is placed in the electronic circuit device place that cooperates with it.

2, the vibrating sensor in the remote-control receiver is the piezoelectric ceramic piece that has additional audio communication box.

3, be welded on the silver-plated weld tabs with lead earlier, then two root beads had the silver-plated weld tabs of lead will be bonded on the two poles of the earth of piezoelectric ceramic piece respectively.

4, the vibrating sensor in the remotely monitored sensor receiver sticks on the sender of mobile phone with adhesive tape.

5, used coding integrated circuit is three 2262 in many yards emissions of diode OR gate formula.

6, in the timing feedback circuit be the form of the self-lock switch formed with two triodes.

7, the electrodeless electric capacity in the timing feedback circuit is to be in series with two electrochemical capacitor negative poles.

8, the vibration damping thing is to use cotton goods to make.

The relevance of above measure further is explained as follows:

1, the principle as the functional device 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.Mainly to act on be exactly the usefulness that receives mobile phone outside the room (" key " mobile phone) calling to used mobile phone among the present invention.It must have two kinds of functions, and first kind of function is the calling that can receive telephone set outside the room, and second kind of function is that the signal that will call out is converted into the function of exporting the signal of telecommunication again.Before mobile phone was failed innovation, it only had first kind of function, and does not have second kind of function.

2, mobile phone itself has receiving function, and call signal is converted into the output signal of telecommunication, the principle that the present invention has adopted vibrating sensor to change.Concrete measure is that vibrating sensor is fixed on the 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 vibration signal.This signal of telecommunication can be introduced in the control circuit.Therefore mobile phone is through after such processing, and its science is that common mobile phone can be converted into a kind of can the reception and exportable remote control dedicated receiver, and this is one.It two is can solve to have only a jack on the 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 the restrictions that are not subjected to mobile phone model, all can adopt this method.

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 the faint signal of telecommunication can be exported in the two poles of the earth of potsherd when adding vibration signal at their the two poles of the earth.If it is fixed on the 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 vibrating sensor in, specification requirement more according to the invention.And present following benefit, and the one, when vibration is converted into the signal of telecommunication, reliable.The 2nd, though the mobile phone kind is numerous, what have has a receiver J-Horner, the earless machine transplanting of rice mouth that has, though have receiver J-Horner arranged, the receiver J-Horner shape is difficult to unified, and after adopting measure of the present invention, can both take out the signal that mobile phone is received with same procedure.The 3rd, easy to operate, as long as with glue piezoelectric ceramic piece is tightly glued on the mobile phone, do not destroy mobile phone integral body fully.The 4th, anti-interference strong, because piezoelectric ceramic piece tightly is bonded on the mobile phone, must mobile phone continuous shaking piezoelectric ceramic piece, just have output.So extraneous general interference is not easy to make it to trigger.After the mobile phone integral body that piezoelectric ceramic piece is fixedly arranged being wrapped vibration damping thing such as towel, the interference in the external world can be reduced to minimum.And as the acoustic vibration transducer similar performance is arranged also with earphone or with the assembly of loudspeaker and output transformer.

4, owing among the present invention, adopted external power supply, so the mobile phone that the present invention powers can long-term work.Do not needed battery of mobile phone.Thereby mobile phone do not relate to the replacing of battery of mobile phone at work, at any time is in the reception stand-by state.

5, among the present invention, the timing feedback circuit plays an important role to the signal reliability among the present invention, have only and adopted it original bell signal could be become reliable control signal, could be operational discreteness, the discreteness of type, and the discreteness of switch, become a kind of unified reliable signal.So stress below must doing:

(1), the meaning of timing feedback circuit: one of after the present invention receives bell signal, it or 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, be to allow the power set that open the door of door start) so, how bell signal reliably promotes radio transmitter circuit, be an important technology key, its reason is because mobile phone is of a great variety, and the ring that has is on-off state, has plenty of continuous state, the signal that has is strong, a little less than the signal that has, if there is not a kind of good timing feedback circuit, be difficult to guarantee reliability of products, and adaptability is widely arranged.Two because the timing feedback circuit has been arranged, so the mobile phone that adapts to is not limited by the requirement of mobile phone model can, be widely, this is one; It two is that the present invention receives to adopt behind the signal radio transmission and execution unit to contact, and any execution unit can add receiving system and realize mating with the present invention, so execution unit that can be supporting also is widely.

(2), the operating principle of timing feedback circuit: (seeing below Fig. 3 and Fig. 4 in the explanation accompanying drawing).

When not receiving signal, first transistor collector is high-order, and the current collection of second triode is very low, not output signal.

After mobile phone has been exported bell signal, be sent to first triode NPN base stage, this moment, current collection was very low, second transistor collector is high, output signal, meanwhile, because the positive feedback branch that electric capacity is formed acts on simultaneously, first transistor base has been added positive feedback voltage, no matter whether mobile phone has signal to be input to the base stage of first triode, it is high that second transistor collector is always, and signal output is arranged all the time, arrived certain hour after, feedback branch electric capacity differential is full of, feedback branch lost efficacy, so positive feedback is regularly, was not eternal.

For this circuit also should illustrate following some:

One of, why to add positive feedback branch, 3 meanings are arranged, one can be the cell-phone bell signal transition of interrupted class a kind of continuous signal, has enlarged the application kind of mobile phone greatly, make to mobile phone require unaffected.Namely whatsoever the mobile phone of model all is suitable for.Its two, guarantee each bell signal, be not subjected to the influence of mobile phone " key " user operation, even operating process is transient state, can both guarantee to launch the required time.This point is very important, because the inventor is applied to the series products of ensuring public security, and non-one of radio coding integrated circuit, but polylith, this is more much longer than the simple radiating circuit time, feedback branch has been arranged after, that is operation of short duration I guess, can both guarantee to launch required time at every turn.Its three, strengthen amplification quantity, particularly more meaningful to the mobile phone type a little less than the bell signal, improved the reliability of control wireless remotecontrol radiating circuit.

Two, this feedback branch is very reliable.Be embodied in following two aspects, first aspect is that feedback procedure is reliable, and this moment, second pipe collector was high, and feedback branch electric capacity is charging process, and the collector resistance of second pipe is fed back the charging of feedback capacity differential, finishes until differential.Second aspect is that the recovery process of feedback is reliable, when first transistor base is input as when low, namely be second triode when full, the positive pole of feedback capacity links to each other with ground rapidly, by saturated triode ground wire is discharged, because saturated pipe internal resistance is very little, discharge time is very short, satisfies the necessary preparation of feedback next time fully.

Three, feedback capacity little with feedback resistance has formed charge constant altogether, adjustable flexibly, be adapted to dissimilar types.

Four, electric capacity selects electric capacity capacious in the feedback branch, the debugging surplus is bigger, be that the electric leakage system is little and choose with electrodeless electric capacity, feedback branch is more stable, if but select electrodeless electric capacity capacious for use, sometimes be difficult for looking for, and price is higher, so proposed in the measure 6 to become electrodeless method with electrochemical capacitor, choose the method that the negative pole of having used two electrochemical capacitors is connected together among the figure, adopt this method after, capacitance can conveniently make up, and leakage coefficient can improve a lot of a lot, in this programme because the positive feedback circuit is arranged, to the stability of raising circuit highly significant.

Five, the reason that positive feedback branch has added diode is when the cell-phone bell signal has been added in the base stage of first pipe, not produce loss of signal branch road.

6, implemented the wireless remote control emission in technical scheme 1 and adopted many yards launch scenarios, important meaning is arranged, main benefit is to be difficult for producing malfunction.Structure of the present invention is that the warning starting switch is the lockhole protection switch, and when cracking lockhole, switch contact is subjected to displacement, and sends the command of execution of having reported to the police, and Telephone set just begins telephone call within doors.Because producing telephone call is a very serious thing, if wrong report, unnecessary terrified with causing, consequence is very serious.And use the apparatus of remote control many now, as locking that the automobile door is protected, with release etc., all want straighforward operation, just formed possible interference source.And adopt the artificial disturbance that just can thoroughly stop this class after many yards.After otherwise many yards radiating circuits have been arranged, must be non-normal door if alarm call is arranged, so have improved the confidence level that the present invention reports to the police greatly.This circuit realizes that its principle of many yards emissions is; When first end output of programme control circut was high-order, it was low that the inverter output that connects makes the chip select of this coding integrated circuit that is connected, this chip select work of institute, and remaining sheet is not worked.Be output as when high when second, in like manner have only corresponding section's chip select work.The 3rd, the 4th reason is the same.Since each the coding integrated circuit with or the door mode be input to modulating tube, so form the form of many yards emissions.

7, after the enforcement measure of the present invention, outside mobile phone in the installation box is not exposed to, so the stranger can not use mobile phone of the present invention and beat outward, steal out the number of reception mobile phone by caller identification, and the people can conveniently start and takes out mobile phone behind the screw cap and change cell phone network number within doors, with conversion phone number at any time to strengthen confidentiality.

Also have following outstanding advantage after the invention process:

1, 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, also can make other long-distance remote control simultaneously and use.

2, mobile phone is a complete integral body, can make the receiving unit of signal transducer, also can be used as mobile phone and independently uses, mobile phone utilance height.Simultaneously, to using mobile phone 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 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.

4, practical, it is of a great variety only to manage mobile phone model, but all is suitable for, and this is the call signal that vibrating sensor can take out the disposable type mobile phone, and the 2nd, external electric supply socket is the standard connector after adopting USB socket, has very strong Practical significance.

5, level of confidentiality height, because one be that the password figure place of mobile phone is many, the 2nd, can often change password.

6, anti-interference strong, avoided the social various electrical equipment that exist of going up to disturb.

7, mobile phone no longer is subjected to the restriction of model, and the mobile phone of magnitude of vibrations all is suitable for.

8, strengthen amplification quantity, make emission more reliable.
