Text Card Using 2D Barcode, Barcode / Voice Reproducing System Using the Same and Reproducing Method

The present invention relates to two-dimensional bar code information recognition, and more particularly, to a text card using a two-dimensional bar code, and a bar code / voice playback system for reproducing the same by voice and a method of reproducing the same.

In general, a barcode is a code that provides information by using an arrangement of bars (black bars) and spaces (white bars). These are codes that are easily readable optically by the rules defined in the barcode language called symbology, and the bars and spaces are changed into one or more binary bits (0 or 1) depending on their width, and a combination thereof. ASCII characters are represented. Characters to be expressed are represented by numbers or letters depending on the type of barcode.

These barcodes are widely used in all fields because they are easy to input data, have low error rate when inputting data, can be composed of data processing system, and can be printed on various materials.

However, the conventional bar code symbol has been mainly used as a data key for accessing a database containing such information, not as a meaningful and decipherable information itself, and the information implied in the bar code symbol is a country code or a manufacturer. The amount of information is limited to the name and product code, so that much information cannot be represented, and if the symbol is damaged, the recovery is difficult.

Complementing this drawback is a two-dimensional (2D) bar code, which is a new symbol lodge that is continuous and multi-layered, and because the symbol size is variable, all ASCII characters can be included. It can be included as a symbol capable of encoding 5000 characters when connecting each symbol.

In terms of its use, the pharmaceutical field already has two-dimensional barcodes that not only manage information but also the efficacy and precautions of drugs. The hospital manages the patient's medical history and treatment history by barcode and wears it on the wrist, and is used to record the details in the test tube for specimen.

If parts installed on an aircraft require urgent investigation, traceability to those parts becomes more important, so two-dimensional barcode symbols can be used.

The 2D barcode symbol contains a lot of data, eliminating the need for an online connection to the host computer's database to obtain information about the person or object to be verified. If information on the disposal or storage of hazardous materials such as radioactive waste is recorded in the symbol, it is possible to check the information as soon as possible without having to check the database in case of emergency.

In addition, since high-density data can be represented, even if a small object does not need to attach a symbol directly on it to produce an additional container for containing the object or the container becomes small, cost reduction can be achieved. In particular, in the case of expensive small retail items such as jewelry and cosmetics, the small symbol does not interfere with the aesthetics, so it is more helpful.

Being able to display high-density data in narrow areas means that data can be displayed in relatively wider areas, in contrast. That is, since the minimum module can be thickened, it can be used for the field of scanning symbols from a long distance.

In addition, unlike the conventional bar code, the two-dimensional bar code can be restored even if the symbol is damaged by 10 to 50%. Recently, it is used for small parts such as NASA, semiconductors, PCBs, tools, metal parts, and medical devices.

In terms of implied quantity and quality, the application fields of 2D barcodes are expected to be various in the future.

On the other hand, in the conventional language textbooks, the language textbooks, which are the main constituents of the present language, are used in a manner of reproducing contents recorded on a cassette tape together with a text book. At this time, it is not easy to repeatedly play a specific part, so you can repeatedly press the rewind and play buttons, or if the player has such a function, it can be used as desired by the user. However, even in this case, finding a 100% satisfactory location was not an easy task, but a lot of effort and time was required.

Conventional early childhood teaching material using a bar code, as shown in Figure 1, by scanning the card (1) attached with the bar code 2, the address of the memory (01, 02, 03 .. As shown in Table 1 below, a simple system for outputting voice data (apples, grapes, bananas ....) stored in the input address has been used.

01 Apple 02 grape 03 banana ... ...

However, the conventional bar code system for early childhood education is extremely simple in its function, and when the consumer wants new contents, there is a problem that even a card (1) to which the barcode (2) is attached and even a memory must be purchased whenever necessary.

In addition, the general bar code has a small amount of information implied in the industry, there is a limit in establishing a systematic management or distribution system with more accurate information of the goods, and there has been a problem that the two-dimensional bar code has not yet become universal. .

Accordingly, the present invention has been made in view of the problems of the prior art, and an object thereof is to provide a text card using a two-dimensional bar code containing a large amount of text content and a two-dimensional bar code capable of real-time audio output using the text card. The present invention provides a barcode / voice playback system.

Another object of the present invention is to provide a barcode / voice reproduction method capable of reproducing text contents by voice using a barcode / voice reproduction system of a two-dimensional barcode.

(Example)

Hereinafter, with reference to the accompanying drawings showing a preferred embodiment of the present invention described above in more detail.

2 is a front view of a text card using a two-dimensional bar code according to the present invention, FIG. 3 is a front view of a two-dimensional bar code according to the present invention applied to a textbook, and FIG. 4 is a bar code reproducing system according to the present invention. 5 is a control flowchart of a barcode reproducing system according to the present invention.

First, referring to FIG. 2, the text card 10 of the present invention, unlike the one-dimensional bar code, has various types of two-dimensional symbols that can symbolize and imply a large amount of text 12 printed on the card substrate 10a. After the bar code 14 is manufactured, the bar code 14 manufactured as a symbol is manufactured by printing on one side margin regardless of the top, bottom, left and right of the text card 10.

In general, two-dimensional barcodes include Code 49, Code 16K, PDF-417, Maxi Code, Code One, Data Matrix, Veri Code, etc. Has been developed.

Each of the two-dimensional barcode method described above has a difference in symbol representation, usage and data capacity and various functions provided, but any method may be adopted in the present invention if there is no problem in data capacity.

In the present invention, a two-dimensional barcode produced using the PDF-417 method will be described as an example.

The PDF-417 symbology is a multi-layered symbology with variable symbol lengths and variable symbol heights developed by Symbol Technologies. The PDF-417 method can contain a large amount of data, and is suitable as a portable data file because it can detect and correct data errors, and can be read by conventional linear laser scanners, linear CCD scanners, and 2D CCD scanners. One symbol in the PDF-417 can represent up to ASCII 1850 characters, 1108 bytes, or 2710 numeric values, depending on the data format.

The PDF-417 symbol consists of a front margin (or left margin), a start pattern, a left column marker symbol character, 1 to 30 data symbols 14a, a right column marker symbol character, an end pattern, and a rear margin.

The contents of the bar code data symbol 14a may be represented by independent voice data.

In addition, the two-dimensional bar code 14 is produced in the form of a sticker instead of the printing method, as well as the text card 10 already made, it is also possible to attach to one side of various other items such as books, printed matters as shown in FIG. Do.

On the other hand, the bar code reproduction system according to the present invention for reproducing the two-dimensional bar code 14, as shown in Figure 4, the two-dimensional bar code (symbolized by symbolizing the content of the text 12 printed on the text card 10 ( 14, a two-dimensional scan unit 30 for receiving a symbol from the symbol, a symbol memory 31 for storing a data symbol 14a extracted from the symbol input through the scan unit 30, and a font necessary for speech synthesis The symbol memory 31 extracts data symbols from the font memory 33 in which data is stored, the voice synthesizer 40 in which a program for performing voice synthesis is stored, and the symbols input through the scan unit 30. Voice data corresponding to a plurality of data symbols stored in the symbol memory 31 and sequentially extracted from the font memory 33 and synthesized by the voice synthesis program of the voice synthesizer 35. After carrying out An amplification unit for amplifying the control unit 35, a D / A converter 37 for receiving D / A conversion of voice data from the control unit 35, and amplifying and amplifying the voice data converted into the analog signal. Part 39 is included.

The playback system of the present invention further includes a microphone 38 for inputting a user's voice into the amplifier 39.

Further, the reproducing system of the present invention further includes a repetitive reproducing key 32 connected to the control unit 35 and generating a reproducing request signal to replay the scanned barcode 14 repeatedly.

The two-dimensional barcode / audio reproducing system of the present invention configured as described above will be described in detail below with reference to the system control flowchart of FIG. 5.

First, the text card 10 is prepared by printing a two-dimensional bar code 14 generated by impregnating the text 12 printed on the card base 10a of the text card 10 in one side margin of the card base 10a. (S10). When the scanning unit 30 is clicked on the two-dimensional bar code 14, the control unit 35, that is, the microprocessor, detects and amplifies the reflected light reflected by the light reflected on the bar code 14 as in the one-dimensional bar code scan. The CPU converts the symbol into a symbol so as to be processed by the CPU, and transmits the symbol to the control unit 35 (S11).

The symbol converted as described above is extracted by the control unit 35, the data symbol 14a is stored in order in the symbol memory 31 (S12).

The stored data symbols 14a are compared by the control unit 35 to compare the code data in which the voice data are stored for each symbol of the font memory 33 (S13).

At this time, the extracted digital voice data is performed by the control unit 35 according to the voice synthesis program, and then converted into an analog voice signal by the D / A converter 37 (S14). Amplified by the amplifier 39 (S15), the speaker (speaker) 36 is reproduced as a voice is output in real time (S16).

In addition, when the microphone 38 is added to the amplifier 39, the user's voice can be output in parallel. This action makes it possible to practice pronunciation in the native or foreign language such as Korean pronunciation or English pronunciation.

In addition, by connecting the earphone jack 34 for connecting the earphone to the front of the speaker 36 may be output to the earphone instead of the speaker 36.

In addition, the present invention is not only a text card 10 using the two-dimensional barcode 14 as described above, but also a two-dimensional barcode 24 containing the text 22 of the text book 20 as shown in FIG. 3. The text book 20 may be used by printing or sticking to one side of the upper, lower, left, and right margins of the text book 20, or may be manufactured by implying information necessary for various fields such as printed matter and general article. The reproduction method is the same as that of the text card using the two-dimensional barcode described above.

The text card 10 using the two-dimensional bar code 14 as described above is a textbook for early childhood education, drawing not only the text 12 of the text card 10 but also a picture of an object or an animal, and the two-dimensional bar code 14 ) Can be used for language learning.

In addition, if the contents of the fairy tale book is produced by the two-dimensional bar code 14 to constitute the fairy tale book together with the illustrations and / or text 12, the parents had to read them one by one using the playback system of the present invention. You can repeat as many children read and see as they want.

In addition, for infants who do not know the letters, the highlights in a particular color prominent around the two-dimensional bar code 14 makes it easy to find the portion of the two-dimensional bar code 14 to stimulate the curiosity of the infant without assistance. You can induce yourself to enjoy learning.

In another example, a commercially available language textbook mainly uses a cassette tape along with a text book 20 to learn and repeat reading and listening.

At this time, if the user wants to listen to a certain part repeatedly, it is necessary to press the rewind and play buttons repeatedly, which is also not easy to play the exact position desired by the user. However, by using the playback system of the present invention, a two-dimensional bar code 24 including the contents of the page is printed or attached to every page of the text book 20 so as to output the contents of the exact position desired by the user in real time. This can greatly improve learning time and efficiency.

In addition, there is a method of repeatedly scanning the bar code 14 with the scan unit 30 for the purpose of repeating the same contents several times. However, when the repeat play key 32 is operated, the scanned bar code is scanned regardless of the number of times. (14) The content can be played repeatedly, so there is no need to repeat the scan one by one.

In another example, the social activities of blind people with disabilities are more discomfort than normal people, the most difficult part of which is the inconvenience of not having access to the media. Of course, there are books and printed materials made out of Braille, but it was all to read them by touching them with the touch of a finger. It takes a long time and requires learning Braille separately. I had to follow.

However, using the reproducing system according to the present invention, if the two-dimensional barcode 14 is attached or printed to a certain portion of the text information and only the position of the barcode 14 is known, many media that cannot be compared with braille are used. Information can be accessed more quickly and quickly, and if it is used in the generalized web field, even the web, which is difficult for blind people, can be used very easily.

The present invention made as described above is used by implying a large amount of text information on a two-dimensional bar code, printed and attached to a text card, printed matter, etc. for use in early childhood education to stimulate the curiosity of children with real-time voice output, seeing and listening You can see the high effect of learning by repeating the learning, and when you want new information, you do not need to buy a memory, you only need to buy a text card or book, you can expect the effect of saving.

In addition, it is possible to improve the learning time and efficiency by repeatedly learning the contents of the exact location desired by the user as a textbook for language learning.

And, in the case of the blind, a lot of media information that cannot be compared with braille can be easily accessed in a short time, and if it is used in a generalized web field, even a web that was difficult for the blind to use can be used very easily. .

Unlike the one-dimensional bar code, which was able to imply only the minimum information of goods for general industrial purposes, it is possible to impose a lot of information, so that it can be useful for more accurate goods management and distribution and thus increase the merchandise.

In the above, the present invention has been illustrated and described with reference to specific preferred embodiments, but the present invention is not limited to the above-described embodiments and the general knowledge in the technical field to which the present invention pertains without departing from the spirit of the present invention. Various changes and modifications will be made by those who possess.
