Abstract

The present invention relates to a braille publishing and reading method and its reading device, belonging to the field of publishing work and printing technology. The invented method is as follows: the contents of a publication are converted into the brailles in turn, and then are stored into its storage medium by microprocessor, and when reading, the braille informations stored in its storage medium are delivered into a reading device which can be used by blind person to make tactile reception one by one by means of its microprocessor, and are displayed in turn, and then can be read. Its storage method is that in the microprocessor, the low six orders of a byte are used to respectively represent the bearings of six points of braille, and "0" or "1" are used for respectively representing "protruding" on "non-protruding" state of each point.

Description

New braille publishing and reading method and reading device

The present invention relates to braille publishing and reading method, belong to publication, print field.

Current blind person reads main by two kinds of means: the first, pass through talking book; The second, pass through books printed in braille.Books printed in braille are to represent the phonetic of Chinese character with outstanding Braille's dot matrix on page, thereby reach the purpose of reading.Just because of its special method for expressing, make that the general volume of books printed in braille is big, publishing and distributing needs special equipment, special personnel, difficulty is bigger, and above-mentioned shortcoming has caused books for the blind quantity, kind less again, make the cost of books for the blind rise jointly, economic benefit is not high.

The purpose of this invention is to provide and a kind ofly publish braille book without the books form, and with storage medium recorded publication contents such as tape, disk, CDs, form with storage medium is published, when needing to read, publish braille book and method and the device of reading braille by the mode that the braille data of storing in microprocessor and the reading device output storage medium is read.

The object of the present invention is achieved like this: convert the content (Chinese character, numeral, letter etc.) of publication to the braille print form successively, deposit storage medium in, by microprocessor the braille information in the storage medium being outputed to the blind person one by one during reading can read with showing successively on the read head of tactilely-perceptible.

The Chinese braille is that the basis is formed by braille print, and braille print is formed (see figure 1) by 6 points.Utilize the different different different letter (initial consonants of representing of counting of these 6 some protrusions with the position, simple or compound vowel of a Chinese syllable) and tone (rising tone, high and level tone, go up sound, falling tone etc.) punctuation mark, numeral etc., (see figure 2) can combine out the Chinese character (see figure 3) into syllables by the letter of braille representative and tone etc.Converting Chinese character to braille print information finishes like this, with in the microprocessor with low 6 orientation of representing 6 points of braille print respectively of a byte, as Fig. 3, represent " projection " of each point or the state of " not protruding " respectively with " 0 ", " 1 ".So just can be with the different conditions of 6 points of each character of braille, with the information stores of " 0 ", " 1 " in storage medium.Read information in the storage medium by microprocessor again when reading, and this information is outputed to topworks's (read head) make Braille's dot matrix on the read head show " projection " or " not protruding " state of each point by the information of output, the blind person is available tactilely-perceptible, reads.

Read head is Braille's dot matrix, and its 6 points can be driven by electric signal, forms the state of " projection " or " not protruding ".

Illustrate that accompanying drawing is as follows:

Accompanying drawings embodiment is as follows:

The method of braille publishing of the present invention and reading is made up of the following step.At first be to convert Chinese (comprising Chinese character, numeral, letter, punctuation mark) to the braille print code, deposit the braille print code information in storage medium then.This storage medium promptly can be used as publication and publishes.During reading the braille print information in this storage medium is read by microprocessor, and export electric signal, drive the state of the Braille's dot matrix each point demonstration " projection " or " not protruding " on the read head, read with tactilely-perceptible by the blind person to read head.

Converting Chinese to the braille print symbol is low 6 orientation (as Fig. 3) of representing 6 points of Braille's dot matrix respectively with a byte in the microprocessor, represents " projection " of each point or the state of " not protruding " respectively with " 0 ", " 1 ".So just Chinese can be converted successively to the information of braille print.Because file storage body (in internal memory, the external memory) all is a linear array, promptly a byte is suffered a byte, has only a coordinate direction, does not have the branch of row, column, page or leaf.So will set a pointer (reading pointer) when reading material, its value begins the byte number of part apart from material for somewhere in the material.Promptly setting the pointer value that material begins to locate and be " 0 ", is one section with a certain byte number (as M), is defined as " page or leaf ".(as L) is one section with another byte number, is defined as " OK " and so can calculates which row of which page or leaf with the value of reading pointer.Chinese converts the information of braille print to can be undertaken by microprocessor, and its flow chart is seen Fig. 5.The code of Chinese and braille print can be looked into promulgation in 1956 " new braille handbook ".Deposit storage medium in by microprocessor after converting the Chinese material to braille print information, this storage medium promptly can the publication form publish and distribute.

During reading the braille information in the storage medium is read by microprocessor, then its information is outputed to read head, drive the each point of Braille's dot matrix on the read head, make it " projection " or " not protruding ", promptly show corresponding braille, the blind person can read with tactilely-perceptible successively.The flow chart of microprocessor is seen Fig. 6 during reading, Fig. 7.

The structural representation of read head is seen Fig. 8.Read head is made up of body, cover plate, base plate, movable thimble, spring, coil.Body (1) is one certain thickness plate to be arranged, and has six holes (totally two row, three holes of every row) thereon, cover plate (2) go up and body on the corresponding position in six holes have 6 apertures so that thimble rod can stretch out.Thimble seat (3) and thimble rod (4) that movable thimble is made by ferromagnetic material are formed.Being with spring (5) coil (6) on thimble rod is placed in the hole.Each read head has six movable thimbles to be placed in respectively in 6 holes of body (1), and leaded coil is drawn.This lead-in wire joins by the parallel port of transistor AND gate microprocessor respectively, (see figure 9), L among Fig. 9 ₁-L ₆Represent 6 coils in the active pointer top respectively, Q ₁-Q ₆For with L ₁→ L ₆The transistor (can be 3DP8) that links to each other.Base plate (7) is installed in body (1) bottom.

During reading when microprocessor from storage medium, read after the braille print information, promptly export " 0 " or " 1 " (representing high level or low level) by the each point of braille print requirement, transistor Q conducting when the output high level, make among the coil L and pass through electric current, therefore movable thimble is picked up its thimble rod promptly to stretch out from the aperture of read head cover plate, and the blind person can touch, when coil opens circuit, movable thimble resets it by spring, and thimble rod promptly enters in the read head body.

Braille publishing method of the present invention and reading device can be simplified the braille publishing formality greatly, reduce the cost of publication, help popularizing the distribution of braille publishing thing.
