Abstract
The invention belongs to a kind of facsimile machine/telephone set method of switching automatically that is used for, it adopts all work of monolithic computer control, by circuit blocks such as off-hook detection, input, combinational logic, drive circuits, discerning the signal that enters on the telephone wire exactly is fax or voice communication signals, and corresponding outside line is forwarded to equipment needed thereby automatically, thereby guarantee that facsimile machine can not produce mutual interference mutually with the shared a pair of circuit of subsets, saved channel resource, facsimile machine powers up automatically, cuts off the power supply, prolonged service life of a machine, energy savings.
Description
The invention belongs to the wirephoto communication technical field, particularly a kind of facsimile machine/telephone set method of switching automatically that is used for.
The prior art relevant with the present invention is CCITT (CCITT) about the T, 4 of G III class facsimile machine and G III, the compatible facsimile machine of G II class, and T, 30 suggestions and State Standard of the People's Republic of China GB3382-82 explain.According to above-mentioned suggestion and regulation, three class phone fax machines are a kind of communication equipments that utilize the single channel voice channel to transmit pictograph, it is mainly by Manuscript scanner input (adopting charge coupled device ccd or closing-type image sensor CIS to be constituted usually), Digital Signal Processing (comprises the compressed encoding and the decoding of graphics text signal, the generation of all kinds of operation signals and processing), modem (being used to produce or receive the signal that is mounted with graph text information that is applicable to the transmission of single channel voice channel), a few major part such as photo information tape deck (being generally the thermal record head at present) is formed.
T, 4, T, 30 suggestion weak points are, if the shared pair of telephone lines of facsimile machine and ordinary telephone set, always common telephone call is exerted an influence, particularly when facsimile machine is in the automatic reception state, the conversation that hangs on as long as user (debit) did not have enough time in 3 seconds to 15 seconds (ring time that facsimile machine is set), receiving equipment will change facsimile machine automatically over to and call out liaison state, if this moment, originating party was common voice communication service, promptly make a phone call usually, will not get through, and owing to originating party is not sent a fax, debit's facsimile machine just can not be realized normal facsimile machine contact, and after after a while, debit's facsimile machine will cut off speech channel automatically.Like this, both sides' phone not only can not be got through, and can take the time of telephone channel more.
Chinese patent bulletin (notification number: CN2037870U) disclose a kind of facsimile machine automatic power supply switch, it is made up of input circuit and amplification control circuit, utilize the next bell signal of outside line through switching circuit, the break-make of control facsimile machine supply line is only worked facsimile machine when needs transmission information.The employing of this automatic power supply switch has changed the operating state that present facsimile machine equipment is started shooting round the clock continuously, thereby can prolong the useful life of facsimile machine, saves energy.But still exist certain limitation, because it can not discern phone and fax, thereby do not solve the problem that influences each other that produces under the shared a pair of circuit situation of present facsimile machine/telephone set.
The objective of the invention is the problem that occurs under the shared a pair of circuit situation of facsimile machine/telephone set, and a kind of new forwarding method is proposed, it can discern the signal that enters on the telephone wire exactly is fax or voice communication signals, and corresponding outside line is forwarded to equipment needed thereby (facsimile machine or telephone set) automatically, thereby guarantee that facsimile machine can not produce mutual interference mutually with the shared pair of telephone lines of subsets.
The objective of the invention is to be achieved through the following technical solutions, described facsimile machine/telephone set automatic forwarding method, be all to work by a monolithic computer (single-chip microcomputer) control, this single-chip microcomputer can be by local user's telephone set off hook signal, local facsimile machine off hook signal and the automatic operation signal of local facsimile machine start, also can be started by inlet wire ring up signal, when bell signal enters, the ring detection part starts single-chip microcomputer, pass through signal detecting part, be no more than in 5 second time, detect by CCITT, T, the facsimile machine call signal of 30 regulations, under the control of single-chip microcomputer,, have only when detecting the facsimile call signal by the connection state and the whereabouts of random logic device control outside line and interior line apparatus, by the Single-chip Controlling relay R, just make facsimile machine energising work, after fax has been operated, facsimile machine is cut off the power supply automatically by the Single-chip Controlling relay;
Under the control of single-chip microcomputer, produce backward signalling and be sent to External Call side through random logic device by the ring-back production part; Produce bell signal and busy-back signal by ringing signal generator and busy-back signal generator, if the programmed decision incoming call is fax, then bell signal sending fax machine, busy-back signal send telephone set, if incoming call is judged to phone, then bell signal send telephone set, the busy-back signal sending fax machine; Under the control of single-chip microcomputer, produce the remote control forced signal by key switch K and remote control signal generator, the remote control forced signal detection part that send the outside line communication counterpart and sent out, receive both sides by random logic device detects, and forces to transfer both sides' connection state to fax by subscriber phone under the single-chip microcomputer effect; If local device will be to outcall, then the equipment of first off-hook (facsimile machine or telephone set) passes through U
4Preferentially connect with outside line, the equipment of off-hook or back off-hook is not then by U
4Cut off binding with outside line.This dialing priority is by off-hook detection parts U
9And U
1Determine that promptly first off-hook person preferentially dials.
According to technical scheme proposed by the invention, also can pass through state signal generator, single-chip microcomputer and random logic device, make when facsimile machine itself is not with phone, insert a substation, when facsimile machine itself has phone, the machine of can answering no longer in addition; Under single-chip microcomputer and random logic device effect, calling is recorded automatically in the time of can increasing recording startup function realization unattended operation phone.
