The specific embodiment of multiloop telephone monitoring and recording system of the present invention is shown in Fig. 4 A, 4B, 4C, 4E.The similar part of this multiloop is only represented with blank square in the diagram, and with the circuit in single loop as an illustration.As previously mentioned, the present invention has consisted essentially of recording access circuit 11, call voice change-over circuit 12, central microprocessor 16, large-scale memory 17, wherein call voice change-over circuit 12 includes the first telephone channel interface 13A, the second telephone channel interface 13B, analog digital speech conversion circuit 14, voice data and control interface 15.Also include semiconductor memory 18 and additional storage 19 in the large-scale memory 17.Wherein recording access circuit 11 is shown in Fig. 4 A, the terminal of TIP1 and RING1 is used for being connected in parallel on the telephone line in the conversation, this telephone wire is the telephone wire that connects between switching equipment and the phone, the T7 coupling transformer provides the input of audio frequency high impedance, and C49 electric capacity intercepts the direct voltage on the telephone wire, makes its unlikely circuit that enters.The recording access circuit can be connected in parallel on the access line in the high impedance input like this, can not produce harmful effect to telephone wire.The audio frequency that is coupled into through T7 is amplified by the U4a amplifier, and carry out automatic gain via Q15, Q16 and control, after regulating the sound size, promote coupling transformer T8 via U4b output, audio frequency TN1 in the talk, RN1 terminal output enters the input that the call voice of Fig. 4 B changes the telephone channel interface among the circuit i2, the coil terminals 4 of T8 is connected to DC power supply, and this DC power supply is also via input terminal T1, the R1 of the telephone channel interface in the call voice change-over circuit 12 of feed-in Fig. 4 B after TN1, RN1 output and the audio mix.
The first telephone channel interface in the call voice change-over circuit 12 and the embodiment circuit of the second telephone channel interface are identical, all shown in Fig. 4 B.The phone calling that both can be connected to recording access circuit or switching equipment arbitrarily enters terminal.Now with the explanation of the first telephone channel interface circuit, below be referred to as the telephone channel interface, as shown in the figure, wherein 20 are the ring monitor, and 21 is audio recognizer, and 22 is speaking circuit, and 23 are the embodiment circuit of dialing receiver.Now be described as follows in regular turn: the audio frequency that is coupled into via recording access is by T1, R1 is through relay tip RL1, this moment, this contact RL1 was when only using for recording, also be T1, the input terminal TN1 of R1 terminal and recording access circuit, when RN1 connects, by CPU control RL1 is remained closed, audio frequency enters speaking circuit 22 via coupling transformer fourth 1 again, the IC U5 of this speaking circuit provides the common path of input with output sound, the audio frequency of input is entered by the 1st pin of U5, by the 12nd pin output enter audio recognizer 21 again bifurcated enter mould/number speech conversion circuit 14 (can consult Fig. 3 C) by the A/D pin, convert simulated audio signal to digital speech data for the storage use.Audio recognizer 21 be with analogue audio frequency through U15, U14 amplifies, export CPU to after the shaping, whether have sound enter, so that voice initiated by this mode determines to begin recording or stops recording if being used for detecting.
In addition, by processing by U15 and U14, the signal tone that various telephone wires produce, as ring-back tone, busy tone, dialing tone ... enter Deng by speaking circuit 22, also after handling, this delivers to CPU, to judge relay tip RL1 release is hung up and made to the phone that outside line is dialled in whether, so that can dial in use again for the external world.Listened to audio archive by far-end remote control and finish the back and hang the call drop machine when the manager dials in through switch by phone like this, this moment, audio recognizer was monitored the signal tone on the telephone wire, whether will hang up circuit with decision systems, dialled in use for other manager.
When being used for far-end remote control and listening to audio archive, the T1 of telephone channel interface circuit, R1 is connected the phone end of switching equipment, start for dialling in phone ringing, optical coupler U3 in the ringing supervision device 20 predicts bell signal and gives CPU affirmation in addition, correct as signal, then starting relay contact RL1 closure is replied, the manager receives by the IC U12 of signal in dialing receiver 23 of phone keyboard input, give CPU after the decoding with recognition instruction, carry out to search audio archive and take out and convert analog voice to through modulus speech conversion circuit (consulting Fig. 3 C), enter U5 via the D/A pin again, T1 is sent on the telephone line, listens to for the far-end remote control manager.The 10th pin of U5 is the input pin after digital speech converts analog voice to.
Referring to the embodiment circuit diagram of the analog digital speech conversion circuit shown in Fig. 4 C 14 with voice data and control interface 15.Wherein XCD0, XCD1, XCD2, XCD3 are used to provide analog voice to convert digital speech to for " CODEC " and convert digital speech to identical each of the integrate circuit function of analog voice independently loop, now be that representative is illustrated, be connected to D/A0, the A/D0 pin of XCD0 via the input of the LC U5 in the telephone channel interface (consulting Fig. 4 B), output pin D/A0, A/D0 with XCD0.The additional storage device of store voice archives such as floppy disk, hard disk, CD in the large-scale memory ... Deng digital speech data, can enter XCD0 by IC U30, U31, U32, U33 and U25, U26, U27, U28 through CPU control and convert analog voice to, export the telephone channel interface to by the D/A0 pin again.In like manner, the analog voice of A/D0 pin input converts the digital speech archives to through XCD0, and through U30, U1, U32, U33 and U25, U26, U27, U28 deposit in the large-scale memory by the CPU control and management.
Monitor the embodiment circuit diagram of switched circuit referring to the present invention shown in Fig. 4 D.
Wherein importation TR1, RP1 are input TIP1, the RING1 that is connected in parallel to the recording access circuit, also can be connected in parallel to output TNI, the RNI (consulting Fig. 4 A) of recording access circuit, because of the two places sound that all can be coupled enters IC U1 through capacitor C 1, transformer T1, U1 is the chess matrix analogue switch, be subjected to CPU control input channel such as U1 pin Y0-Y15 can be connected to output pin X0-X7 according to need, also be that Y0 can connect with arbitrary pin of X0-X7, Y1 also can connect with arbitrary pin of X0-X7, and the rest may be inferred.Be example with X0 among the U1 output X0-X7, after its output is amplified via U2a, U2b, be coupled to terminal TX1, RX1 via T8, TX1, RX1 are connected to input terminal T1, the R1 (referring to Fig. 4 B) of the second telephone channel interface 13B in the phone voice conversion circuit 12, the sound of conversing this moment is given far-end through this feed-in switching equipment 50 beeper listens to, and realizes monitoring.U3, U4, U5, U6 are used for accepting signal that CPU sends here through the TRX0-TRX15 pin to control U1 monitor required phone to connect the internal switch path after changing.
Referring to the block diagram of the central microprocessor shown in Fig. 4 E 486 with the semiconductor memory additional storage.Wherein semiconductor memory includes SRAM, DRAM, ROM, and additional storage includes hard disk HDD, cd cd-ROM ... Deng, can be connected with other partial circuits of the present invention by ISA interface or pci interface, realize goal of the invention.Because embodiment is to use personal host computer plate circuit, does not add at this and gives unnecessary details.
