Abstract

The utility model discloses the braille conversion appearance who announces, the sound that can convert the characters on the books to the braille that can feel and can listen to. It includes character recognition unit, microprocessor, serial communication module, voice broadcast module, the prominent module in braille contact. The character recognition unit is equipped with the image recognition sensor, and this module links to each other with microprocessor, signal that microprocessor gathered out through the processing, control braille the contact work of prominent module and the sound production of voice broadcast module. The all nickel cadmium cell of mistake of this department supply power. The utility model discloses can make things convenient for braille study and exchange, turn into braille and sound with the characters, the processing data is swift, and the operation is stable.

Description

Braille conversion device

Technical field

The present invention relates to a kind of by the identification device that text conversion is braille and sound, out and convert bookish Text region to standard braille and sound, help blind person's reading or identify that the external world indicates.

Background technology

At present, according to national authority department statistics, China is the country that blind person is maximum in the world, and the quantity of blind person increases with huge quantity every year, and their life and learning level receive the increasing concern of society. Because they can't see thing by eyes, can not be the same with normal person, see that bookish word learns by eyes, only by both hands, word is identified by touching the braille round dot of various combining form, so cumbersome and time consuming, in order to facilitate blind person to identify word, we devise the braille conversion device that bookish text conversion can become braille and sound. Having had it, blind person just by using it that bookish text conversion becomes sound and standard braille, can use for learning and communication. Now, in special school, it is by opening at cardboard, pricks out the braille round dot of various combining form with pin herein above, learn bookish word by instructing in words and by deeds help blind person, so significantly waste time and money, there is bigger problem. And the appearance of braille conversion device can well alleviate this problem.

Summary of the invention

In order to facilitate the learning text of blind person, the present invention provides braille conversion equipment, braille conversion device to be possible not only to the text conversion on textbook is become standard braille, it is also possible to convert the knowledge that sound learns on textbook for blind person to. Its novelty apply image recognition technology to identify bookish word, through signal processing, the text conversion that will identify that is highlight the braille round dot on hardware surface, its stability is high, Text region accuracy is high, stable, it is fast to process data, solve and blind person's study and the social problem linking up inconvenience, have great significance in ensureing blind person's legitimate rights and interests.

This invention address that technical problem the technical scheme is that the braille conversion device of the image recognition technology of a kind of application innovation, highlight module, the chargeable nickel-cadmium cell of 5V, detection module, braille data transmission blocks including word recognition unit, microprocessor, serial communication modular, voice broadcast module, braille contact.Braille conversion device be shaped as rectangle, it is divided into two large divisions, a part is the image processor of Text region, the operation principle of similar scanner, to literary composition carries out real time scan, scan the word of certain area, convert them into the signal being available for microprocessor processes, pass to microprocessor by integrated circuit and detect signal accordingly. At Part II, it is integrated with microprocessor, sound module and braille viewing hardware, by processing the corresponding letter signal identified, convert sound and the word of correspondence to, pass through contact switch, eject the round dot of various combination form, form the braille of corresponding word composition, touch perception braille form for blind person. Its compact, it is simple to carry, accurately identifies out the braille corresponding to corresponding word and sound. Meanwhile, serial communication modular, it is possible to as required by the braille information record that highlights on computers, facilitate record queries, it is achieved the detection that program is run, the collection of Word message, storage.

The present invention brings and provides the benefit that, word can be converted into the braille highlighted and personalized sound by it, facilitates blind person to identify bookish word. In science and technology, the character recognition technology that it is applied has important scientific and technical innovation meaning; In application, its human oriented design can help the better learning and communication of blind person socially, have great significance in protection blind person's legitimate rights and interests, has promoted government to help the disabled the development of utility.

Detailed description of the invention

The present invention provides the braille conversion device of the image recognition technology of a kind of application innovation, highlights module, the chargeable nickel-cadmium cell of 5V, detection module, braille data transmission blocks including word recognition unit, microprocessor, serial communication modular, voice broadcast module, braille contact. Braille conversion device be shaped as rectangle, it is divided into two large divisions, a part is the image processor of Text region, the operation principle of similar scanner, to literary composition carries out real time scan, scan the word of certain area, convert them into the signal being available for microprocessor processes, pass to microprocessor by integrated circuit and detect signal accordingly. Its volume is 1/3rd sizes of general textbook, only need to place it on books, it is possible to the word under the institute of detection in real time area coverage, is converted into being available for the signal of microprocessor processes. At Part II, it is integrated with and prays for processor, sound module and braille viewing hardware, by processing the corresponding letter signal identified, convert sound and the word of correspondence to, pass through contact switch, eject the round dot of various combination form, form the braille of corresponding word composition, touch perception braille form for blind person. Both combine between the higher and lower levels, and make braille conversion device compact convenient. Algorithm in microprocessor, screens through science, is delivered to by the Word message met and highlight module and voice broadcast module to braille contact, carry out touching audible operation. Serial communication modular, it is possible to as required by the Word message record of display on apparatus such as computer, facilitate record queries. Accurately identify and demonstrate braille corresponding to corresponding word and sound.
