Abstract

The invention discloses a digitized voice information publishing device, which comprises a micro-programmed control unit (MCU), a serial interface, an external detection and control circuit, a voice synthesis chip, an audio amplification circuit, an automobile horn and a working indicating circuit, wherein one end of the serial interface and one end of the external detection and control circuit are connected with a general packet radio service (GPRS) automobile stage, and the other end of the serial interface and the other end of the external detection and control circuit are bidirectionally connected with the input end of the MCU respectively; the voice synthesis chip, the audio amplification circuit and the automobile horn are connected in turn; and the input end of the voice synthesis chip and the input end of the working indicating circuit are connected to the output end of the MCU respectively. The invention aims to provide a digitized voice information publishing device with a simple structure, a reasonable structural design and a good information publishing effect.

Description

A kind of digitized speech information distributor
[technical field]
The present invention relates to a kind of digitized speech information distributor.
[background technology]
Present voice messaging distributor structure design is reasonable inadequately, and the information distribution effect is poor, can not satisfy people's demand.In order to overcome above-mentioned technical matters, inventor spy designs this patent.
[summary of the invention]
The present invention has overcome the deficiency of above-mentioned technology, provides a kind of simple in structure, reasonable in design, the digitized speech information distributor that the information distribution effect is good.
For achieving the above object, the present invention has adopted following technical proposal:
A kind of digitized speech information distributor includes MCU, serial interface, external detection and control circuit, chipspeech, audio power amplifier circuit, horn trumpet, working indicating; Described serial interface, external detection is connected with the GPRS ride with an end of control circuit, serial interface, external detection is connected with the MCU input end is two-way respectively with the other end of control circuit, described chipspeech, audio power amplifier circuit, horn trumpet connects in turn, the input end of described chipspeech, the input end of working indicating is connected on respectively on the mouth of MCU.
The invention has the beneficial effects as follows:
1, this equipment cooperates the GPRS ride to use, and the digitized speech data of receiving remote is reduced to audio oscillation, sends by loudspeaker, and integral structure is simple, and is reasonable in design, and it is defeated stable that signal passes p, and the information distribution effect is good.
2, the unlatching of power supply is controlled by external host, saves electric power.
3, may command switching horn trumpet connects former car sound equipment or speech packet.
[description of drawings]
Fig. 1 is a circuit block diagram of the present invention.
[specific embodiment]
A kind of digitized speech information distributor includes MCU, serial interface, external detection and control circuit, chipspeech, audio power amplifier circuit, horn trumpet, working indicating; Described serial interface, external detection is connected with the GPRS ride with an end of control circuit, serial interface, external detection is connected with the MCU input end is two-way respectively with the other end of control circuit, described chipspeech, audio power amplifier circuit, horn trumpet connects in turn, the input end of described chipspeech, the input end of working indicating is connected on respectively on the mouth of MCU.This equipment cooperates the GPRS ride to use, serial interface is by the digitized speech data of GPRS ride receiving remote, MCU control chipspeech is reduced to audio oscillation with the signal of receiving, and the process audio power amplifier circuit sends voice messaging by horn trumpet after carrying out the signal amplification.This distributor integral structure is simple, and is reasonable in design, stable signal transmission, and the information distribution effect is good.
It is the chip of 89C58 that described MCU adopts model.Described chipspeech model is XF3011.It is the chip of LM4871 that described audio power amplifier circuit adopts model.It is the chip of SP202EEN that described serial interface adopts model.It is the chip of TLP521 that described external detection and control circuit adopt model.
