Abstract

A touch and talk machine comprises a touch screen and a control box, wherein the surface of the control box is provided with a voice play hole, an LCD display screen, a control keystroke and a CCD barcode scanner; the control box is internally provided with a microprocessor, a barcode recognition module, a storage module, a voice play module, a keystroke module, a display module, the barcode recognition module, a coordinate processing module and a power module; and the barcode recognition module, the coordinate processing module and the touch screen are respectively connected with the microprocessor. In the touch and talk machine, the barcode technology is utilized to automatically recognize the types and pages of books, thus avoiding complicated interaction and input and manual input error, and greatly improving use convenience; and the transparent touch screen is adopted to directly cover the books and confirm the coordinate of the clicking position, thus having no need to use special clicking pen and improving use convenience; and the integrated one-board type structure of the touch screen and the control box is adopted, thus having simple structure and convenient carry.

Description

Point reader

Technical field

The utility model relates to a kind of point reader, and the particularly a kind of kind and page number that utilizes bar code identification technology to discern books automatically utilizes transparent touch screen to confirm click location and the point reader that the speech play of relevant position is come out.

Background technology

At present, the point reader of market sale is varied, but its basic special card all is that books are placed on the panel of hinge-type of point reader, arranges the conductive film circuit on the point reader panel, determines the position coordinates of click by the induction of special click pen.Its defective is to need extra click pen.

In addition, point reader in the market can not be discerned the book-type and the page number that is placed on the point reader automatically.Need the interactive operation of a series of complexity of user could import and confirm the current book-type and the current page number.By LCD and key combination, often need 5～10 operations could import and confirm the current book-type and the current page number.If the book-type of input and the page number and current actual the placement are not inconsistent, all clicking operation can not be play correct voice.Its defective is a complicated operation, makes mistakes easily.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, discloses a kind of point reader, utilizes bar codes technique to discern the kind and the page number of books automatically, avoids complicated mutual and input.Adopt transparent touch screen to directly overlay on the books simultaneously, utilize touch-screen to confirm the position coordinates of clicking, click pen that need not be special.

The technical solution of the utility model is: comprise panel and control enclosure, be provided with speech play hole, LCD display, control key combination and bar code scanner on this control enclosure surface; Microprocessor, memory module, speech play module, key-press module, display module and power module are installed in control enclosure, it is characterized in that: described panel is a touch-screen; Also be provided with the coordinate processing module, this coordinate processing module all links to each other with microprocessor with described touch-screen.

The utility model compared with prior art has following remarkable result: utilize bar codes technique to discern the kind and the page number of books automatically, avoid complicated mutual and input, improve the convenience of using greatly and avoid artificial input to make mistakes; Adopt transparent touch screen to directly overlay on the books, utilize touch-screen to confirm the position coordinates of clicking, click pen that need not be special has improved the convenience of using, and avoids making the special click pen of safeguarding complexity simultaneously; Adopt touch-screen and control enclosure one one-board structure, simpler than hinge typed structure, be convenient for carrying.

Embodiment

Below in conjunction with accompanying drawing the utility model point reader and embodiment are further described.

Referring to illustrated in figures 1 and 2, a kind of novel point reader comprises touch-screen 11 and control enclosure 12.Touch-screen 11 and control enclosure 12 are one one-board structural designs, are convenient for carrying.Be provided with speech play hole 121, LCD display 122, control key combination 123 and CCD bar code scanner 124 on control enclosure 12 surfaces, microprocessor and peripheral circuit are installed in the control enclosure 12.

Referring to shown in Figure 3, embodiment hardware of the present utility model comprises microprocessor 3, the coordinate processing module of forming by 5 wire resistance type touch-screens and touch-screen dedicated processes chip 1, CCD bar code scanner 124, speech play module 6 (comprising power amplifier and loudspeaker), button control module 5, LCD display module 4, and Flash storer 7 and power module (not shown).Microprocessor 3 links to each other with coordinate processing module 1, CCD bar code scanner 124, speech play module 6, button control module 5, Flash storer 7 and LCD display module 4 respectively by bus.LCD display module 4 is as the driver of LCD display 122.

Described CCD bar code scanner 124 adopts bar code identification technology, read the bar code information that is printed in advance on each page of books, bar code scanner utilizes self light source irradiation bar code, utilize photoelectric commutator to accept the light of reflection again, convert the light and shade of reflection ray to digital signal.The bar code of Yin Zhiing is made up of dead zone, bebinning character, data character and final character in advance.Data character is the main information content of bar code, comprises book-type and page number information.

Described data character information embodiment is: preceding five digit number is represented book-type, can identify 99999 kinds of dissimilar books.Back three bit digital are represented the current page number, can represent 999 kinds of different page numbers.Illustrate,, show that books on the current point reader are that label is 23 pages of 12 books if the data character of bar code is " 00012023 ".According to the bibliography that pre-establishes, the point reader processor finds out the voice content that label is the 23rd page of 12 a books automatically.

The utility model CCD bar code scanner 124 is for adopting CCD as photoelectric commutator, and LED can realize autoscan as the scanner of illuminating source.It is characterized in that reading various materials, uneven lip-deep bar code, cost is also comparatively cheap.Described barcode scanner is divided into following a few part: light source, receiving trap, photoelectric conversion part, decoding scheme.The irradiate light of being sent by light source is above bar code symbol, the light of returning that is reflected passes through optical system imaging on photoelectric commutator, be interpreted as the digital signal that microprocessor 3 can directly be accepted through code translator, digital signal passes to point reader microprocessor 3 by serial ports.Described touch-screen 11 and coordinate processing module 1 are the transparent absolute positioning system of a cover.Need not special click pen, can adept finger or common soft style of writing touch.Embodiment adopts 5 wire resistance type touch-screens, and (X, physical location Y) are converted to the voltage of representing X coordinate and Y coordinate to touch panel sensor with touch point in the rectangular area.By the touch screen controller chip of special use, the click location coordinate is passed to analog to digital converter (ADC) on the sheet of microprocessor 3.Point reader microprocessor 3 is searched according to click location and is play corresponding voice messaging.

Referring to Fig. 1～Fig. 4, the utility model point reader in use, directly transparent touch-sensitive panel 11 is covered on the books, its workflow is as follows: CCD bar code scanner 124 reads the bar code that is printed in advance on the textbook, bar code data is passed to microprocessor 3, search and confirm the current book-type and the current page number.LCD display 122 shows the current books title and the current page number.The user clicks touch-screen 11, and touch-screen dedicated processes chip is handled the coordinate of click location, and coordinate information is passed to microprocessor 3, searches and play the voice messaging of this position.
