Embodiment

Consult Fig. 1, the utility model is by casing, telephone set network, central processor CPU circuit, information gathering and preserve the DSP circuit, power circuit is formed, telephone set network, central processing unit, information gathering and preservation DSP circuit connect power circuit respectively, central processing unit answer the call machine circuit, information gathering and preserve the DSP circuit, telephone set network and information gathering and preservation DSP circuit mutual connection also meet civil power outside line T, R.

Consult Fig. 2, it is telephone set network figure, adopts the common key-press telephone set network, and this circuit is the core of hardware components, and it is finished the transmission of various voice signals and guarantees speech quality, comprises following a few part: 1. ringing circuit:

The ringing signal of the 25Hz 90V that switch is sent here is superimposed upon on the 48V feed voltage, is added on the BU9 (LS1240) by BC59, BR61.By to after in addition rectification of ringing signal, filtering, the voltage stabilizing, trigger the oscillating circuit of its inside, produce bell signal.One the tunnel directly sends into the buzzer sounding; Another road draws a tinkle of bells detection signal by the light lotus root, sends into central processor CPU, makes CPU obtain prompting, carries out various processing then.2. speaking circuit

This part circuit adopts U.S. Motorola last word BU8 (MC33215) to finish.This chip is finished sending, being talked about of receiver altogether, hands-freely send, is talked about.The inner sidetone that also comprises of BU8 (MC33215) is eliminated accessory circuits such as the amplifying circuit of network, double-tone frequency, AGC automatic gain control circuit.By central processor CPU four port: SPS, MUTE, PRS, the LSM of BU8 (MC33215) carried out the level setting, can finish control the various states of BU8 (MC33215).3. handle is met sb. at the airport

By SPK2, DP, MUTE, PRS are put high level, receiver MIC and receiver to be opened, the MIC signal is coupled to 9 pin and 10 pin of BU8 (MC33215) by BC69, BC70.By the inner amplification of BU8 (MC33215), deliver to outside line through BQ9, BQ10 again with signal.The signal that same outside line comes from the output of 32 pin, promotes receiver after delivering to the 2 pin input amplification of BU8 (MC33215) through BQ9, BQ10.4. hands-free meeting sb. at the airport

By DP, LSM, MUTE, DDS, SPS are put high level, then BU8 (MC33215) is in the hand-free call state, MIC information is from 11 pin, the input of 12 pin of BU8 (MC33215), outside line is delivered in amplification through inside, the signal that outside line comes is sent into 2 pin of BU8 (MC33215) through BQ9, BQ10, and carry out internal signal and handle and power amplification, export from pin.This wherein also includes the comparison circuit that send, talked about, and makes BU8 (MC33215) be in the half-duplex state, and can make hands-free volume and send the size of words to satisfy higher requirement, and can self-excitation.

Referring to Fig. 3, it is information gathering and preserves the DSP circuit that this circuit mainly is made up of BU25 (TC88411), BU24 (V53C317405A), BU23 (MC27C020).Finish sampling, compression, A/D and D/A conversion and information storage to voice signal.

The concrete signal flow process is roughly as follows:

In conjunction with Fig. 2, Fig. 3, the voice signal that the MIC1 from Fig. 2 enters is exported from 7 pin by 6 pin that BC29, BR91 are coupled to LM324.When central processing unit CPU puts high level to 12 pin of BU13 (TC4066), go into from 10 pin of BU13TC4066 from the signal that 7 pin of LM324 are exported, 11 pin go out, deliver to 78 pin, 79 pin of BU25 (TC88411) again by BC119, BR239 among BR54, Fig. 3 among Fig. 2, deposit among the BU24 (V53C317405A) after the DSP processing of circuit.BU23 (MC27C020) is in order to storage suggestion voice and software program.

The information that outside line comes also can be saved on this machine, and signal flow is roughly as follows:

When dialing loCal number, this power ringing circuit working.Photoelectric coupling circuit BU11 sends into central processor CPU after detecting bell signal, central processor CPU is put high level with the DP pin automatically behind the tinkle of bells for several times, give connection to external call, the outside line signal can be delivered to 9 pin of LM324 by BQ9, BQ10, sends into by BR90, BC28 from the output of 8 pin to deposit in the BU24 (C317405A) after information gathering is handled with 78 pin of preserving the DSP circuit and 79 pin again.

The utility model can be gone out the information transfer that is kept at the DSP circuit, and signal flow is roughly as follows:

In conjunction with Fig. 3, the signal of DSP circuit 81,82 pin output passes through the inner processing and amplifying of BU8 (MC33215) after BQ9, BQ10 deliver to outside line and go by 8 pin that BC25, BR51 among Fig. 2 are coupled to BU8 (MC33215).

The process of the utility model specific implementation transinformation is as follows:

When this telephone set is dialed in the strange land, behind the several the tinkle of bells, central processor CPU is put high level with DP, SPS, MUT, PRS.Telephone set enters response status automatically, can hear voice suggestion.During by " # " key, double-tone is coupled to 2,3 pin of LM324 frequently through BC128, BR113, BC129, BR112, export from 1 pin.Send into the DSP circuit again.When the DSP electric circuit inspection goes out this signal, feed back to central processor CPU, CPU gives various instructions again, and the information that then deposits in the DSP circuit can be transferred to the strange land.

If set in advance and shifted the number of phone, and new information is arranged, the utility model can be dialed the telephone number that presets automatically, fresh information is transferred to the telephone set that presets.

The flow process of signal is roughly as follows:

Fresh information, is seen off from BQ9, BQ10 through the inner back of amplifying of BU8 (MC33215) by 8 pin that BC25, BR51 are coupled to BU8 (MC33215) from 81 pin, the output of 82 pin of DSP circuit.

Referring to Fig. 4, it is a central processor CPU, adopts that BU3 is a reset circuit among 8 single-chip microcomputer BU1 (E0C88112), the figure, and BU2 (HT9200A) is dial-up circuit, produce dtmf signal.

Consult Fig. 5, it is a power circuit, and the each several part circuit is supplied with in filtering output after the employing LM7805 voltage stabilizing.
