Abstract

The utility model discloses a vehicle mounted telephone with the voice prompt. The internal circuit of the host machine of the vehicle mounted telephone comprises a single-chip computer, a digit GSM module, a speech chip, an integrated circuit IC1, an integrated circuit IC2, and a horn. The GSM module is connected with the serial port of the single-chip computer; two wires are connected between the single-chip computer and the speech chip; one wire is used to transmit the data, and the other wire is used to transmit the resetting control signal. The audio output terminal of the speech chip is connected with the integrated circuit IC1, the integrated circuit IC2, and the horn in sequence. After the system receives the incoming call, the vehicle mounted telephone with the voice prompt can report automatically the number of the incoming call or the name of the incoming call person, and the vehicle mounted telephone with the voice prompt receives the incoming call automatically after the incoming call rings five times. After the system receives the short message, the vehicle mounted telephone with the voice prompt can report the number of the incoming call and the content of the short message automatically. Because of the system having natural and fluent report of the short message and favorable effect of the incoming call, the diver can release the hands so as to concentrate on driving; therefore, the security for driving is enhanced.

Description

A kind of car phone with voice suggestion

Technical field

The utility model relates to a kind of car phone, particularly a kind of car phone with sound prompt function.

Background technology

Traditional car phone does not have sound prompt function, and receiving must be by charactron or liquid crystal display caller ID behind the incoming call, and the attentiveness when this can disperse to drive has undoubtedly increased some unsafe factors.Traditional car phone is after receiving note, if show and not support Chinese short message, the motorist can't obtain short message at all, promptly allows to show note, and the motorist checks that note can largely take sb's mind off sth, can be very dangerous when the speed of a motor vehicle is very fast.

Summary of the invention

The utility model provides a kind of car phone with voice suggestion in order to overcome the above unfavorable factor of traditional car phone.Receiving that incoming call back system can report caller's number and identity automatically, start auto-pickup then, do not need to carry out any operation around here.After receiving note, motorist caller's the number and the full content of note can be informed in the mode of voice by system, allow the motorist experience untrammeled communication.

This car phone with sound prompt function, circuit is mainly by single-chip microcomputer in its main frame, gsm module, speech chip, integrated circuit (IC) 1, integrated circuit (IC) 2 and loudspeaker constitute, speech chip is by the asynchronous communication serial ports, text identification, phonetic synthesis, D/A converter module is formed, it is characterized in that: being connected to of circuit in the main frame: gsm module links to each other with the serial ports of single-chip microcomputer, there are two lines to be connected between single-chip microcomputer and the speech chip, one passes data, one passes reseting controling signal, the audio output of speech chip successively with integrated circuit (IC) 1, integrated circuit (IC) 2 links to each other with loudspeaker.

It is by finishing according to the following steps that function is reported in described voice suggestion:

(1) incoming information is reported, after receiving for the first time the incoming information that the logical gsm module of numeral sends, carry out following operation: a. and abandon ongoing note report, b. caller ID sends to the rearview mirror demonstration, if comprise caller's name in the c. incoming information, then stores conversion, after receiving for the second time the incoming information that gsm module sends, carry out voice suggestion, by the time receive the incoming information that gsm module sends for the 6th time after, carry out auto-pickup;

(2) button is reported, and in communication process, follows trunk tone during button, and sends the dual-tone multifrequency data;

(3) short message is reported, and after gsm module received note data, main program called note storage conversion program after confirming current not conflict, carry out note subsequently and report.

The utlity model has the car phone of sound prompt function.After incoming call is received by system, can report caller ID or caller's name automatically, auto-pickup behind the jingle bell five.After note is received by system, can report caller ID and short message content automatically.The utility model report incoming call effect is true to nature, and it is natural, smooth to report note, makes human pilot can free hand to concentrate one's energy drive, and has improved the fail safe of driving.

Embodiment

The utility model will be further described in conjunction with the accompanying drawings.

The purpose of this utility model can realize by following measure: circuit is mainly by single-chip microcomputer in the main frame of car phone, the logical gsm module of numeral, speech chip, integrated circuit (IC) 1, integrated circuit (IC) 2 and loudspeaker constitute, speech chip is by the asynchronous communication serial ports, text identification, phonetic synthesis, D/A converter module is formed, being connected to of the interior circuit of main frame: gsm module links to each other with the serial ports of single-chip microcomputer, there are two lines to be connected between single-chip microcomputer and the speech chip, one passes data, one passes reseting controling signal, the audio output of speech chip successively with integrated circuit (IC) 1, integrated circuit (IC) 2 links to each other with loudspeaker.

At first will understand the course of work of speech chip, it can realize the conversion of any Chinese text to voice.This chipspeech has three kinds of synthesis modes: prompt tone, customization is synthetic and arbitrary text is synthetic.Prompt tone is sound or the music of prerecording, and its effect is best.Customization is synthetic to be meant according to the field speech chip of certain format writing and can to discern.Such as the date write as " 04/25/2004 " so chip be read as " on April 25th, 2004 ", adopt synthetic writing style and the speech habits that meet people of customization.For other texts, speech chip can only adopt arbitrary text synthetic, and is poorer slightly than prompt tone aspect the tone and continuity.In addition, speech chip is supported some control signs when handling text.Such as " 1861 ", both can be read as " 1,861 " with the numerical value pronunciation, also can be read as " the one eight six the one " in the mode of number, when sending text, increase these control signs and can improve the intelligibility of prompting greatly.With regard to this special applied environment of car phone, after incoming information or note are received by system, the logical gsm module of numeral can send to single-chip microcomputer to incoming information or short message, single-chip microcomputer needs to carry out some text-converted after receiving information, mainly be that agreement according to speech chip increases some synthetic control commands, control sign or the like.

Particularly, after car phone is received incoming information, gsm module sends to single-chip microcomputer to the content of incoming information, single-chip microcomputer is responsible for butt joint collection of letters breath and is carried out text-converted, comprise the extraction caller ID, add synthetic order field, prompt tone according to the speech chip agreement, synthetic control sign makes the caller ID of receiving broadcast with the form of telephone number.As after receiving incoming call, system prompt: " * (prompting music) caller ID: * * * * * * * * (caller's number) ", if comprise caller's name in the incoming information, system prompt: " * (prompting music) * * * (caller's name) incoming call ", auto-pickup behind the jingle bell five.

If note is received by system, same, single-chip microcomputer also needs to extract incoming call number and short message content, and adds synthetic order field and prompt tone etc., then the good text of conversion is sent to speech chip and synthesizes.After note is received by system, system prompt: " * (prompting music) receive from * * * * * * * * note of (caller's number): * * * * * * * * (short message content) ".
