Description

Intelligent electronic printing system

The present invention relates to a kind of intelligent electronic printing system, belong to computer information processing, control automatically, printing, machinery manufacturing technology field.

At present, about per minute 160 words of the average input speed of professional's keyboard (seeing the 40th page of Yuhang Publishing House's in May, 90 version " Chinese information processing technology ").

The purpose of this invention is to provide the computer input of a kind of automatic on-keyboard input method, intelligence and output control card, easy no film makeup system, high-precision digital control system, lightweight offset press at a high speed.

The object of the present invention is achieved like this: multiple-language input method is imported block letter with the image acquisition program and the graph scanning mode of intelligent control card, handwritten form recognizer and this input method input handwritten form with intelligent control card, form is that each word (mother), punctuate, symbol account for 1 lattice, in particular cases also can account for 2 lattice, can write across the page or perpendicular writing; This law solves the segmentation problem of handwritten form and grid with optical filtering technique, and the photoelectric conversion section of scanner receives only non-danger signal, the grid elimination of danger signal, just can obtain having the handwritten form of certain intervals.The image acquisition turntable driving and the program of intelligent control card are carried out man-machine conversation by screen display, working method, state and the various parameter of input are set, as device type, class-mark, resolution, scan area, grid, density, gray scale etc., send order by main frame to scanner, adopt inquiry mode to receive the data that transmit.Under pattern manipulation interface (as Windows), various literal all are counted as figure, and block letter is broken down into dot matrix input computer with the form of graph scanning.Monochrome image is to produce analog electrical signal through optoelectronic scanning, becomes digital signal by analog to digital conversion again; Coloured image is except that having increased the RGB(RGB) the scan function, the image acquisition principle is identical with monochrome.The handwritten form recognizer becomes analog information to hand-written character and graphic by the optoelectronic scanning of scanner, become numerical information through analog to digital conversion again, after binaryzation, carry out pretreatment stage, text profile after handling is extracted font style characteristic compares with the standard font of storage in advance, float and mate, computed range is obtained the maximal value of the two similar degree, is recognition result.The type matrix reducing program is reduced into dot matrix to precision compression type matrix, generates different fonts and font size on request, and font can be done various distortion, but the font size stepless zooming becomes doubly.Page generator program carries out man-machine conversation by screen display, working method, state and the various parameter of output are set, as device type, output area, resolution, grid, density, gray scale, colourity, function etc., send order by main frame to output device, adopt inquiry mode to receive the space of a whole page data that main frame transmits.Generator program is divided into 8,16,32,64 memory pages to the whole space of a whole page according to space of a whole page data volume size, and each page is the memory data output of 8MB, finishes 1 page in order at every turn, until generating full page.The optoelectronic switch of intelligent control card gated sweep instrument makes electron beam at very close sweep trace in interval of the up formation of the original copy page, until finishing full page.The handwritten form recognition result of scanning input converts the figure (containing the block letter word) of computer character code and input to, and image is placed on earlier in the buffer memory, after the full page been scanned, is sent to main frame through S IS C communication interface; Intelligent control card converts the character information of code form to dot matrix accurate type matrix, again the figure of the space of a whole page, image, character data are placed on the assigned address of buffer memory on request, corresponding each point that generates the page of each of the buffer memory page, after the whole buffer memory page is finished, sequentially each point is sent into video port synchronously; Control card makes laser beam generating scanning repeatedly on the page according to space of a whole page data message control optical signal switch, forms a superfine helix, until finishing the whole space of a whole page.Digital control system adopts SCC secondary control structure, main frame is finished analysis, calculating, the processing of data, in time send priority parameters to controller then, finish the adjusting of process control by controller, come speed governing by pulsed frequency, make stepper motor Fast starting, speed change, counter-rotating, braking etc.The lightweight offset press is assembled into complete machine by machinery, electric parts such as the shell of plastics, aluminium alloy and spare and accessory parts, stepper motor, hollow roller bearings.

Manual input is compared with keyboard, and the present invention has easy (need not be familiar with various codings), practical (can be used as the novel input tool that substitutes keyboard), (optoelectronic scanning input), efficient advantages such as (being about manual 5～10 times of importing) automatically.Compare with existing handwritten form recognition technology, multiple-language input method has increased the recognition capability of various literal handwritten forms (prior art can only discern one, two kind), and intelligent control card has improved the recognition speed (be about prior art 3～5 times) of handwritten form.Compare with existing laser photo-typesetting controller, intelligent control card has increased the control to scanning input, has realized that computer input, output control are integrated; Digital control system has increased the process control to phototypesetting, has improved the repeatable accuracy of film setter.Compare with existing mask-making technology, directly forme-producing system can save graphic arts film and equipment, has reduced operation, has improved work efficiency, has reduced cost.Compare with existing offset press, the lightweight offset press has alleviated weight, has improved rotating speed and digital control system combines, and also can improve running accuracy, realizes the offset printing robotization.

Implementation of the present invention is as follows: figure (containing printing type face), image are imported with scanner, the above large format of A4 is imported with digital camera, handwritten form word (red ruled paper Chinese regular script is write) adds intelligent control card input with scanner, refuses character learning and writes in the red lattice with regular script and re-enter.Promptly set type after the justifying input, the colored space of a whole page is divided into red, yellow, blue, black four looks through color separation software, composing (color separation) check and correction after printer is drawn a design, by intelligent control card commander's laser printer or directly record plate-making on carrier of film setter, digital control system run-in synchronism, guaranteed high-quality plate-making precision, the version that makes is loaded onto offset press (colored examination seal back is to make a plate again or formal printing according to the printing effect decision), the lightweight offset press high-quality, is finished whole printing process at a high speed, expeditiously automatically under the commander of digital control system.
