Abstract

The utility model provides an additionally arranged device of a multi-function telephone set. The multi-function telephone set is composed of an infrared probe, a door bell for dialogue, a signal sample circuit, an A/D converter, a relay, an encoder, a double-tone encoder, a speech chip and an SCM. After the device is connected in parallel to a telephone set line, signals obtained by the infrared probe or a doorbell trigger switch are sent to the A/D converter via the sample circuit; then data is sent to the SCM. The SCM controls the relay to ensure a switch to switch; the circuit of double-tone encoder and the circuit of the speech chip are conducted; the telephone line is connected; the telephone set can automatically dial to conduct a paging station, send out paging call and alarm speech.

Description

A kind of multi-function telephones machine

The utility model relates to wired communication field, specifically adopts a kind of adjunct circuit device and teleset line to join, and has increased the function of use of phone.

Along with the development of communication career, home-use phone increases, and bring many convenience for people's live and work, but the device of telephone set multi-purpose machine also still lacks.

The purpose of this utility model provides a kind of multi-function telephones machine.This device can be when the telephone set owner goes out, and the signal with the people in the illegal inlet chamber or visiting guest touch doorbell switch sends paging by telephone line from trend paging centers, notice phone owner.

The utility model is achieved in that two inputs of signal sampling circuit link to each other with the doorbell trigger switch with infrared probe respectively, and output is connected with A/D converter.A/D converter output and single-chip microcomputer P ₀Mouth joins the P of decoder and relay and single-chip microcomputer ₁Mouth connects, and decoder output is connected with diphthong coding.Telephone signal sample circuit input is connected on the telephone line, and output and A/D converter input join.Infrared alarming signal or doorbell signal are through sample circuit and A/D converter input single-chip microcomputer, and the Single-chip Controlling relay makes switch on and off, and conducting diphthong coding device circuit, telephone line sample circuit and language sheet circuit are connected telephone line.The dial data of depositing in the single-chip microcomputer is through decoder, by the automatic dial-up of diphthong coding device circuit paging centers, the language sheet sends the calling alarm language, the doorbell triggering signal dials to the paging of automatic paging platform by single-chip microcomputer and diphthong coding device, and relay switch is connected telephone set and intercom doorbell circuit simultaneously.

Below in conjunction with accompanying drawing enforcement of the present utility model is elaborated.

Fig. 1 illustrates the general structure of this multi-function telephones machine.Alarm signal sample circuit input is connected with infrared probe, and output is connected with A/D converter; Doorbell signal sampling circuit input connects the doorbell trigger switch, and output is connected with A/D converter; Telephone line signal sampling circuit input and telephone line join, output termination A/D converter.The signal sampling circuit output end signal also one the tunnel through or the door be connected with single-chip microcomputer INT; Another road meets single-chip microcomputer P ₂Mouthful.A/D converter output and single-chip microcomputer P ₀Mouth connects.Sample circuit obtains digital signal through A/D converter after obtaining alarm signal or doorbell signal, and the signal enabling singlechip interruption program of warp or door transfers the A/D converter digital signal to enter in the single-chip microcomputer simultaneously.

Decoder input and single-chip microcomputer P ₁Mouthful connect, relay 1, relay 2, relay 3, relay 4, with single-chip microcomputer P ₁Mouth connects.Enter the digital signal of single-chip microcomputer, make switch on and off through the working procedure control relay.Relay 1 operating switch K ₁Connect, phone is in off hook state, and telephone line signal sampling circuit input and telephone line are connected simultaneously, and during the ceases to be busy sound, relay 2 work make K switch ₂Connect, thus conducting diphthong coding device circuit.Because diphthong coding device circuit input end links to each other with decoder, the digital data of storing in the single-chip microcomputer dial corresponding number by the diphthong coding device automatically through decoder, connect paging centers.Relay 3 work make K switch ₃Connect, language sheet circuit and telephone line are connected and are sent paging, warning language.The doorbell signal is when sending paging, and Single-chip Controlling relay 4 makes K switch ₄Connect, thereby entryphone and teleset line are connected, this moment, entryphone substituted the telephone set use.

Figure 2 shows that the alarm signal sample circuit.By infrared probe, signal amplifier, R ₁, C ₁, triode BG ₁, R ₂, rectifier diode D ₁, D ₂Form signal sampling circuit with relay.Infrared probe obtains signal and obtain d. c. voltage signal after amplifying rectification, through D ₂, K _A-2Enter or door and A/D converter, this signal is through D simultaneously ₁Make C ₁Through R ₁Be charged to certain hour BG ₁Saturated and conducting, relay A makes K switch _A-1, K _A-2Disconnect, make sampling obtain a twinkling signal (designing its voltage is 3V) like this, enter or door and A/D converter.C ₁Pass through R again ₁, BG ₁Base stage one emitter-base bandgap grading, R ₂Discharge, R herein ₂Can select higher value, extend discharge time.

Fig. 3 illustrates the entryphone signal sampling circuit.By trigger switch, resistance R ₃With voltage stabilizing didoe D ₃Form, touch trigger switch, output can produce a voltage signal (being designed to 2V), sends into or door and A/D converter.

Shown in Fig. 4 is the telephone line signal sampling circuit.By K switch ₁, coupling device, amplifying circuit, triode BG ₂And BG ₃, composition such as relay B.Its end points a, b and telephone line are connected, and relay 1 makes K _1-1, K _1-2Connect no signal BG on the telephone line ₂Saturation conduction.If during ceases to be busy during sound, signal makes BG by amplifying circuit on the telephone wire ₂End, transmitting terminal produces continuous high voltage.Through D ₅A rectification output constant voltage (designing its voltage is 8V).If during blind tone signal, BG ₂Transmitting terminal then produces the discontinuity high voltage, through D ₅After the rectification, voltage is half of ceases to be busy sound voltage.Two kinds of voltage outputs obtain can judging after different numerical value numerals enters single-chip microcomputer to be ceases to be busy sound or blind sound through A/D converter.C ₂, R ₅, R ₆, BG ₃, JB forms the charge and discharge circuit, and is identical with Fig. 2 circuit, BG ₃Saturation conduction relay B makes K _B-1, K _B-2Disconnect.

Figure 5 shows that the connection line figure of entryphone and teleset line in this device.Relay 4 is connected, and makes K switch _4-1, K _4-2, K _4-3, K _4-4, K _4-5, K _4-6Conducting, phone and entryphone are connected.Can be by push switch K on the entryphone _cThe off-hook of realizing phone with hang up, press K switch _cDoorbell loudspeaker, microphone and phone are subjected to words to send the words circuit to connect, and just can talk with by entryphone this moment.
