Description
Technical Field
The utility model belongs to the technical field of the blind information technology and specifically relates to a system and device for automatically checking printing quality of braille readings.
Background
The braille, also called dot and convex, whose minimum unit is "square", is composed of six dots arranged and combined according to a certain concave-convex fluctuation rule, and is a character designed for visually impaired people and perceived by touch, and is also a main written communication tool for visually impaired people.
International active Braille "Braille (Braille)" was created in 1824 by louis Braille for french blind. According to the Braille system in 1952, on the basis of old blind characters such as 'Xingmming blind character', and the like, China proposes a scheme (commonly known as 'current Braille') for spelling new blind characters of the common Chinese by adopting a word segmentation continuous writing method on the basis of the common Chinese and the Beijing speech as a standard through adjustment and innovation, and the scheme is published and promoted in 1953 in China. It has 18 initials and 34 finals, and the initial consonants and vowels are double-spelled into a syllable, and another blind symbol is used as tone mark. Thus, China has unified braille. In 2018, in 7 months, the Chinese language and character work Committee is approved by the Standard approval Committee of the national language and character work Committee, and is formally implemented by the national Universal Braille project agreed by the Chinese disabled person Association, the education department and the national language and character work Committee. The method continues to use the initial consonant, the final sound, the tone and the mark symbol of the current braille, does not change, delete or add any symbol, only perfects the tone marking rule of the current braille, and standardizes the use of the tone symbol.
Due to the fluctuating arrangement of the braille characters and the spelling attribute of the universal braille scheme, if errors occur in the point positions of the braille characters, the touch reading and understanding of the blind can be seriously influenced. In the publishing process, the electronic book of the braille reading materials typeset by the computer needs to go through a plurality of proofreading and checking links so as to ensure that the error rate before printing is less than one per thousand. The printing process of the braille readings is to present the electronic manuscript of braille on the base materials such as paper, plastic or metal by various mechanical electronic devices, such as the solid braille is printed by depending on the foaming ink bump printing method, the thermoplastic forming method, the UV dispensing method, the silk screen printing method and the ink-jet printing method; or by means of a printing machine or an imprinter, the surface of the paper with higher hardness and strength is deformed by mechanical rolling and impact, and the like, so that the raised or depressed hollow braille is formed. In the process of printing the braille readings, printing errors, such as missing dots, multiple dots or wrong dots, caused by abnormal execution of the mechanical electronic device often occur, so that the braille readings are corrected and checked again after being printed, and the error rate in the printing process is reduced. However, in the prior art, if the blind is invited to perform touch reading and proofreading on the printed braille readings word by word and line by line according to the proofreading and checking mode of the electronic book of the braille readings, more manpower and time are required to be invested, and the technical problem of extremely low efficiency is caused.
