Abstract

The utility model provides a wireless automatic audio guide device, which comprises a wireless read head, a master control module, a speech synthesis module and an audio amplification module which are connected in sequence, wherein, the wireless read head acquires the identification address of the label information, and the master control module amplifies the synthetic speech in the audio amplification module and automatically conducts speech guided reading through analyzing the address information and utilizing the speech synthesis module.

Description

Wireless automatic speech navigator

Technical field

The utility model relates to a kind of electronic equipment, especially a kind of wireless automatic speech navigator.

Background technology

Some speech guide devices have been adopted at home some major museums and scenic spot, for the visitor provides the various guides that mediate a settlement that separate, greatly facilitate the understanding of visitor to museum and scenic spot history culture.But traditional speech guide device function ratio is more single, power consumption is big, cost is high, Data Update is complicated, and the visitor needs manual input coding just can obtain corresponding broadcast information, has limited further promoting the use of of speech guide device.

Summary of the invention

The shortcoming of the speech guide of for a change above-mentioned traditional voice navigator hand-coding, the utility model provide a kind of wireless automatic speech navigator.

The utility model comprises wireless read head, main control module, phonetic synthesis module, audio frequency amplification module, it is characterized in that, wireless read head, main control module, phonetic synthesis module, audio frequency amplification module connect successively, wireless read head obtains the identification address of label information, main control module utilizes the phonetic synthesis module that synthetic voice are amplified from the audio frequency amplification module and carries out the automatic speech introduction by analyzing address information.

The beneficial effects of the utility model are that employing wireless mode introduction is searched for automatically, and is easy to use, has good practicability and economy.

Description of drawings:

Fig. 1 is a schematic diagram of the present utility model, and Fig. 2 is the utility model electricity structural drawing.

Embodiment:

As shown in Figure 1, the utility model comprises wireless read head 1, main control module 2, phonetic synthesis module 3, audio frequency amplification module 4, wireless read head 1, main control module 2, phonetic synthesis module 3, audio frequency amplification module 4 connect successively, wireless read head 1 obtains the identification address of label information, main control module 2 utilizes phonetic synthesis module 3 that synthetic voice are amplified from audio frequency amplification module 4 and carries out the automatic speech introduction by analyzing address information.。

As shown in Figure 2, RFID read head circuit is delivered to microcontroller with the label information that obtains.Microcontroller reads corresponding text information and delivers to the TTS sound-compound-circuit by serial ports according to label information from data-carrier store.The TTS sound-compound-circuit is converted to voice messaging with text message, delivers to built-in loudspeaker or external earphone then after audio amplifier circuit amplifies.Simultaneously, LCD display shows present tour according to label information.In addition, can inquire about some information on services by man-machine interface.EM4095 is a RFID base station read-write chip, the carrier wave frequency of operation is 100～150kHz, can operate a Chinese speech synthesis chip that the XF2S3011 chip is the research and development of news Fetion breath Science and Technology Ltd. of Chinese University of Science and Technology to labels such as EM400X, EM4050, EM4150, complete speech synthesis system is fully integratible into single processor inside, receives and synthesize arbitrary text by serial ports.The serial ports baud rate is 9600bps, and by the present duty (Busy/Ready) of RAD port indication speech chip.Because the sound signal power ratio of XF2S3011 chip output is less, in order to make sound signal enough power drive loudspeakers is arranged, and need carry out power amplification by the LM4871 circuit, gain amplifier can be regulated by resistance R.

Claims

1. wireless automatic speech navigator, comprise wireless read head (1), main control module (2), phonetic synthesis module (3), audio frequency amplification module (4), it is characterized in that wireless read head (1), main control module (2), phonetic synthesis module (3), audio frequency amplification module (4) connect successively.
