Therefore, the identification of bar code information is used and to be restricted, and be difficult to use in the occasion that is not easy to use a computer or be inconvenient to read display message, and eyesight inconvenience person also can't be known information needed by bar code reader.
On the other hand, if the information translation that bar code reader is obtained becomes voice signal, common contemplated methods has two kinds: a kind of is to set up special lexicon, with certain bar code and corresponding vocabulary coupling, when being identified in this bar code, call the voice messaging of corresponding vocabulary from lexicon, realize pronunciation, this mode only is applicable to some application-specific, can not promote the use of, corresponding bar code reader does not possess versatility yet; Another kind is, convert bar code information to word information relates earlier, convert voice signal to literal-speech conversion system again, this mode, data volume pending during conversion speech signal is big, and the corresponding bar code canned data of is limited, thereby is not suitable for the portable device use of little shape.
Summary of the invention
The object of the invention provides a kind of optical-acoustic conversion method of bar code information, can effectively the information translation that bar code is expressed be become voice signal by limited combination, and applicable to making portable reader;
Another object of the present invention provides this bar code information reader.
For achieving the above object, the technical solution used in the present invention is: a kind of optical-acoustic conversion method of bar code information, make up the bar code information storehouse according to the sounding of voice, and corresponding each sounding with phase unisonance and accent is provided with a bar code; Make up sound bank, each voice in the sound bank and described bar code are constituted corresponding relation; Recognition method for the information carrier that uses described bar code is, adopt optical scanning way that bar code is scanned, transmits, according to the voice position of the structure retrieval correspondence after handling, call the voice in the sound bank, utilize playing device to convert speech data to voice signal; Successively the bar code that scans is carried out above-mentioned processing, realize the optoacoustic conversion of bar code information.
In the technique scheme, described voice mainly are made of Chinese character pronunciation, and wherein said sounding with phase unisonance and accent is meant the Chinese character sounding that pinyin syllable is identical with four tones of standard Chinese pronunciation tone.
The sounding quantity of Chinese character is less, according to statistics, comprises four tones of standard Chinese pronunciation tone, and the pronunciation of Chinese is only about 1000 kinds.Therefore, a bar code combination surplus only needing to design 1000, corresponding Chinese speech pronunciation can be realized above-mentioned information transmission and optoacoustic conversion by bar code.Certainly, also can increase the English alphabet pronunciation, perhaps,, realize the information stores and the pronunciation of other languages by the mode of the corresponding International Phonetic Symbols.
Adopt the bar code information reader of said method, comprise optical scanning and pre-processing assembly, also comprise register, data distributor, memory and speech processor, the output of described optical scanning and pre-processing assembly is delivered to data distributor and speech processor through register, storage has the voice messaging that is made of the sounding corresponding to each sound and accent in the described memory, comprise processing module and speech utterance module in the described speech processor, this processing module converts the bar code data of identification the address signal of voice messaging to, and calls voice messaging driving speech utterance module sounding.
Wherein, described speech utterance module is made of power amplifier and loudspeaker.
During use, information after utilizing bar code reader to bar code scanning, transmission, processing, deliver to data distributor and language processor via register, then a plurality of memories that link to each other are carried out sheet choosing and addressing, promptly to barcode encoding default with a plurality of memories in the addressing in audio frequency paragraph districts such as spoken language, music of corresponding coupling of typing, thereby the corresponding paragraph district that drives memory is called, through the language processor output audio signal, by power amplifier signal is amplified to loudspeaker and plays sounding again; Because of a unisonance individual character paragraph district only used in the unisonance Chinese character that adopts a large amount of existence, and when a large amount of group speech, this class unisonance holophrastic speech section district called repeatedly and make it sounding, and the practical function in unisonance individual character paragraph district has obtained very big expansion when making a large amount of groups of speech, realized more easily by the optical scanning bar code, and transmission, be treated to the conversion effect of playback of audio information such as spoken language.
Because the technique scheme utilization, the present invention compared with prior art has following advantage:
1. the present invention changes into the mode of the corresponding sounding of bar code with the mode of the corresponding speech processes of common literal, has realized the information transmission and the optoacoustic conversion of bar code; Under this mode, it is nonsensical converting bar code information to literal, yet, when converting voice to, but realized the full detail transmission under the little transmission quantity; Thus, overcome thinking of the prior art blind area, made bar code have new application prospect;
2. the present invention is converted to the acoustic intelligence that has that can listen with the coded message of bar code, expanded the purposes of bar code, with the address in audio frequency paragraph districts such as the spoken language in the typing memory, music and the codes match of bar code, make the paper media that the is loaded with bar code information publication that can vocalize.Simultaneously, a kind of study and converter tools are very easily provided for blind person, eye disease patient and children.
