Description

Multi-purpose telephone set

The utility model relates to a kind of multi-purpose telephone set circuit.

At present, reach the employed telephone set of huge numbers of families on the market and can only be used for " making a phone call ", in the prior art, multi-feature telephone is arranged, dtelegraphone, television telephone set etc. are also arranged, though function is many, its function all " makes a phone call " to design for the Convenient telephone user, also have telephone alarm (patent No. 98240902), but do not see multi-purpose telephone set.

The purpose of this utility model is that telephone set not only can be made a phone call, and can be used for signal (audio frequency) transmission of remote control, remote measurement etc.The utility model provides a kind of simple in structure, controller circuitry that cost is low, in the telephone set network of packing into, simultaneously telephone set give orders or instructions path, receive on the words path and respectively adorn a jack Z ₁, Z ₂, to realize above-mentioned purpose.Concrete controller circuitry of the present utility model is provided by following explanation and accompanying drawing.

Fig. 1 is controller circuitry figure.Figure Central Plains telephone set signaling circuit, receipts telephone circuit, originating circuit, bell circuit all draw with square frame.In order to illustrate, also draw original call machine hook switch Ya, Hands-free key K1a, receipts bell circuit are every straight coupling capacitance C4, overcurrent protection resistance R ₅, rectifying bridge type diode D ₃-D ₆, voltage stabilizing didoe D ₁₂, filter capacitor C ₅Fixed current polarity bridge diode D ₇-D ₁₀, overvoltage protection diode D ₁₁

Fig. 2 is circuit capacitance C shown in Figure 1 ₁On voltage waveform.

Fig. 3 is a circuit shown in Figure 1, in NE555 (3) pin output voltage U ₀Waveform.

Fig. 4 is the line map (is that example is drawn with HA283TD type telephone set) that circuit shown in Figure 1 inserts the telephone set respective point.

Controller circuitry is made of following four parts: a microswitch K ₂, a midget relay J, a timer made from NE555, a triode Q ₁The mains switch of making and one are connected in parallel on Q ₁Jack Z between emitter and collector ₃Describe working condition in detail below in conjunction with Fig. 1.

Timer is integrated package NE555 and peripheral resistance R thereof ₁, R ₂, capacitor C ₁, C ₂The astable circuit that constitutes of connection routinely, R ₁, R ₂, C ₁Constitute charge circuit, its power supply Vc is 6 volts, supplies with triode Q with four joint dry cells ₁(3DG12) make switch, be serially connected in the current supply circuit.NE555 (3) pin is an output, meets midget relay J (5 volts of operating voltages), at C ₁In the charging process, (3) pin is a high level, its voltage U ₀Be about 5.2V, it is moving that J is inhaled.J has two windings point, and first group is Ja, Jb, and second group is Jc, Jd, the moving spring J of the first winding point _MConnect with the back contact 1 of phone hook switch Ya, back contact Ja is connected on and receives in the bell circuit, and normally opened contact Jb is in parallel with the normally opened contact 2 of phone hook switch Ya; Second group back contact Jc and diode D ₂Negative pole connect moving spring J _NWith triode Q ₁Emitter E connects, normally opened contact J _dWith triode Q ₁Collector electrode C connect.Make cell switch triode Q ₁Drive current, take from potentiometer W ₁(5k Ω) when ringing signal, regulates W ₁Make Q ₁Base stage B to the voltage V between emitter E _BE=0.5v-0.7v makes Q ₁Be operated in the saturation region, power supply Vc is switched on, timer work.During no ringing-current, Q ₁End, power cutoff, timer can not be worked.Multipurpose selector switch K ₂Be dpdt double-pole double-throw (DPDT), work as K switch ₂When double-pole was pulled 1,3 positions, ringing-current was through diode D ₃-D ₆Bridge rectifier, D ₁₂Voltage stabilizing, C ₅After the filtering, from K switch ₂Through R ₃Deliver to W ₁Make Q ₁Saturated, switch connection makes NE555 enter operating state.Work as K ₂When double-pole is pulled 2,4 positions, make ordinary telephone set and use.

Is work like this with astable circuit as timing controlled: when the other side transfers to loCal number after telephone office connects this machine, from outside line L ₁, L ₂Send ringing-current here, make Q ₁Saturated, connect timer power supply Vc, Vc is through resistance R ₁, R ₂To C ₁Charging, charging during this period of time in, NE5 55 (3) pin output high level, it is moving that relay J is inhaled, first group of normally opened contact Jb and the moving spring J of J _MClosure has been connected the path of this telephone set with telephone office, and from L ₁, L ₂Send DC power supply here, supplied with this telephone set each several part circuit.While Ja and moving spring J _MSeparately, so the receipts bell circuit that broken makes Q ₁End aspect in addition, second group moving spring J _NWith normally opened contact J _dClosure has kept the power path of NE555, makes C ₁Continue charging, work as capacitor C ₁On voltage U c when being charged to 2/3 Vc, charging stops to transfer to discharge, NE555 (3) pin becomes low level from high level, relay J discharges, and is returned to the state before the work.At this moment C ₁On voltage U c by diode D ₂, relay back contact Jc powers to NE555, this is a discharge loop, another discharge loop is through R2 discharge to NE555 (7) pin to (1) pin, so electric charge has been put very soon.Find out that from the described Uc wavy curve of Fig. 2 timing circuit only is operated in the AB section of curve, every work once repeats the AB curve once, the charging interval of capacitor C 1: T=1.1 (R ₁+ R ₂) C ₁

T generally can choose in 7 minutes at 3 minutes, and in exemplary embodiments, its value is down:

Get the T=1.8 branch, then R ₁=1M Ω, R ₂=3K Ω, C ₁=100 μ f; Get the T=3.6 branch, then R ₁=2M Ω, R ₂=3K Ω, C ₁=100 μ f; Get the T=7.2 branch, then R ₁=2M Ω, R ₂=3K Ω, C ₁=200 μ f.D among the figure ₁Be the protection diode, D ₂This path is only to give C ₁Discharge and be provided with.

The position and the effect of 3 jacks are described below in conjunction with Fig. 4.

Three-way two core jack Z ₁But wiring be connected on the point of the path input signal of giving orders or instructions common Z ₁Be in parallel with transmitter, deliver to the input socket of the other side's telephone set as outer signal by this machine, when inserting connector, transmitter is disconnected.

Three-way two core jack Z ₂Wiring be connected on the point of receiving the exportable signal of words path Z normally ₂In parallel with receiver (or hand-free loudspeaker), as the output socket of signal from this telephone set of the other side's telephone set warp let-off, when inserting connector, receiver (or loud speaker) is disconnected.

Two wires two core jack Z ₃Wiring be connected in parallel on cell switch pipe Q ₁On the two ends of emitter (E), collector electrode (c), as the insertion mouth of the outer start-up control device of machine.

When making multi-purpose telephone set, to indicate Z ₁, Z ₂Matched impedance and level value, when making socket connect external equipment, can mismatch.
