Abstract

The invention relates to a Braille electronic dictionary providing a simple and convenient tool for learning, reading and translating Braille for ordinary people. The Braille electronic dictionary comprises special Braille-Chinese translation V1.0 software and a host machine; the software is communicated with the host machine through a USB interface; the host machine comprises a Braille square point matrix input area, a display area, a circuit control mainboard and a loudspeaker, wherein the Braille square point matrix input area is provided with a three (15 points) Braille square operating area completely same as Braille input. A user only needs to input the Braille to be translated and Braille tones through typing in the Braille operating area according to the corresponding Braille to betranslated, then corresponding Chinese pinyin and candidate Chinese are displayed on a Chinese display screen, so that the user can find out the Chinese characters and words needed from the candidateChinese characters according to the Chinese pinyin. The Braille electronic dictionary has simple structure and easy operation and is especially suitable for ordinary people and low-vision children tolearn Braille, thereby having the advantage of wide application.

Description

Braille electronic dictionary

Technical field:

The present invention relates to a kind of Braille electronic dictionary, particularly relate to the utensil of a kind of ordinary people's study, reading braille, belong to blind person's accessory technical field.

Background technology:

Braille is the important means in the blind people know world, also is the important way that the ordinary people exchanges with the blind person simultaneously.But because in existing braille teaching process, also do not have a kind of simple and easyly, be applicable to that easily the ordinary people learns the instrument of braille, the means that the ordinary people helps the blind person to read braille are short of.This present situation makes has brought very big difficulty on written communication between ordinary people and blind person.Simultaneously also propose a new problem, how can help the ordinary people to learn braille effectively, helped the ordinary people to understand blind person and their culture, promoted communicating with each other and understand between the people.Braille electronic dictionary can solve braille religion accessory and lack, and the ordinary people helps the problem of blind means shortcoming, improves the condition that present ordinary people learns braille.

Summary of the invention:

The objective of the invention is to overcome the above-mentioned defective of existing ordinary people in reading the braille process, provide a kind of suitable ordinary people to read, learn the light instrument-Braille electronic dictionary of braille, this tool construction is simple, and is easy to operate.

Technical solution of the present invention is:

Braille electronic dictionary comprises the blind Chinese special compiling V1.0 special software and two parts of Braille electronic dictionary main frame.The special compiling of blind Chinese V1.0 special software adopts C Plus Plus to write, and is opening install software, passes through USB interface communication, the built-in ID verification of main frame with main frame; Host circuit comprises master controller AT89C51, high capacity memory, key entry control circuit, coding circuit, sound circuit, communication interface circuit, display control circuit; Main machine structure is by braille six side's self-locking dot matrix input fields, the viewing area, and circuit control main board, housing, LCD display, loudspeaker are formed, can be according to input Braille and the corresponding corresponding Chinese phonetic alphabet and the alternative Chinese character of showing of tone.

Because the present invention is provided with in Braille electronic dictionary with braille and imports identical three parts (15 point) operational zone, braille word side, the braille that the user only needs need translate according to correspondence writes braille and the voice tone that needs translation with the mode of keying in the operational zone, just have the corresponding Chinese phonetic alphabet and alternative Chinese to show on Chinese characters display screen.The user just can search required Chinese words and speech according to phonetic in alternative Chinese character.

15 braille word sides of special use in Braille electronic dictionary formula structure that is designed to rebound, the concavo-convex and true directions of braille point is identical, realizes that feel, voice, demonstration develop simultaneously in the study of braille and search procedure.After adopting technique scheme,

It is strong that Braille electronic dictionary of the present invention has intuitive, is easy to grasp, and promptly can be used for the children that the ordinary people also can be used for low vision, utilizes voice can quote the braille content of input at any time.This apparatus structure is simple, easily operation.Can solve the problem that braille religion accessory lacks with the method, be particularly suitable for the ordinary people and use.Also can be used for low eyesight children's braille study simultaneously.Made things convenient for the user widely.The efficiency of teaching of raising and quality are arranged, broad-spectrum advantage.This equipment can also be as the external equipment of common computer or blind person's dedicated computer system.

Description of drawings:

Fig. 1 is the circuit theory diagrams of Braille electronic dictionary of the present invention;

Fig. 2 is a Braille electronic dictionary front view of the present invention.

Fig. 3 is the structure schematic side view of Braille electronic dictionary of the present invention.

Fig. 4 is the configuration structure synoptic diagram of the special compiling of the blind Chinese V1.0 special software of Braille electronic dictionary of the present invention.

Below in conjunction with accompanying drawing and instantiation the present invention is described.

Fig. 1 has described the circuit theory diagrams of Braille electronic dictionary of the present invention, the host circuit that comprises AT89C51 type master controller 10, master controller 10 connects coding circuit 20, display circuit 60 simultaneously, is furnished with the key entry control circuit 30 of a plurality of buttons, sound circuit 70, and is connected with computing machine by USB communication interface 8.

Fig. 2 has described Braille electronic dictionary profile front view of the present invention.Comprise the main frame 1 that contains control circuit, the operational zone 2 of 15 braille word sides is arranged on the panel of main frame 1, acknowledgement key 4, key for searching 3, display screen 6, acoustical generator 7.Only need during use 15 braille word sides 21, key in braille word or the speech that to search on 22, simultaneously in mark accents side 23, key in corresponding tone,, have voice suggestion simultaneously by on Chinese display screen 6, just having the braille Chinese phonetic alphabet of correspondence behind the acknowledgement key 4 and alternative Chinese character or speech shows; Key for searching 3 can be provided at the function of selecting suitable word or phrase in a plurality of Chinese characters or the speech.Illustrate: the braille of 2 key entry need translations is for example in operational zone, 15 braille word sides :- (Chinese " machine " word) at first keyed in first party 21

Second party 21 is keyed in

Key in " one " sound key in mark accent side 23 Pressing acknowledgement key 4

After, determine to import content and also an input content is preserved.This moment, coding circuit 20 position encodedly sent master controller 10 to by decoding scheme with 6 in the braille word side that is triggered, master controller 10 carries out the braille information processing by the special compiling of blind Chinese V1.0 special software with the Chinese phonetic alphabet and the character library tabulation of Braille, shows the Chinese phonetic alphabet " j " and " i " and respective alternative Chinese character of braille correspondence on display screen 6.For example: " several, and, machine, long-pending, anxious ... " etc.What promptly be shown as: ji (note and machine skill).The user utilizes options button
