Description
Technical field
The information that the present invention relates to transmits field, in particular to a kind of picture channel and information transmitting methods thereof.
Background technology
Existing bill is when transmission of information, the information character be passed prints on the paper of bill by computer system control printer, information character on paper comprises Chinese character, numeral, letter and other punctuation mark, these characters can by people's direct reading identification, when the identification of needs computer system, a kind of OCR of general application (Optical Character Recognition, optical character identification) technology, scanner scanning is first used by bill to input computer system for picture file, computer system starting runs a kind of OCR software program and carries out identifying processing to image, the information for computer system that OCR software program exports on bill uses, this belongs to a kind of information processing of automation, information exchanging process need not input information by personnel, the thing that personnel do is some back works, such as bill is put into scanner, start-up simulation electromechanical source, start the functional performances such as relevant software programs.Under this using forestland, when bill paper is simply connected, printing type is laser, ink-jet, temperature-sensitive, when any one such as hot transfer printing commonly use printing technique, all without any problem, when bill paper is multi-joint, paper material can use NCR, each connection of NCR all scribbles one deck carbon ink, the vestige of pressure spot can be left on paper when being under pressure, during this multiple part bills use several printing techniques printings above, because printing principle is not that physically low-pressure knocks printing, so first can by the upper content of printing, several below then can be blank, this situation can not meet user demand, improve, need to use impact printer, impact printer knocks colour band by pin and prints on paper by information, because the feature of the transmission of percussion power and NCR, several stroke that also can occur all characters below of multiple part bills, form the information equally complete with first, this multiple part bills, in people's Direct Recognition, or during computer system use OCR technology identification, each connection all can Direct Recognition.For computer system obtaining information, this information exchanging process is that input information is to paper to image output information again.
The technical characteristic of existing bar-code label technology when transmission of information and implementation are, by CARR model by information coding and print on label, printing device uses bar code dedicated printer, printing principle is hot transfer printing, after on bar code printing to label, people not directly identifies, need the barcode scanner using barcode scanner to be namely commonly called as to sweep bar code, barcode scanner is aimed at the bar code on bar-code label, identifying that the information identified to be sent into computer system for further and process by the data wire that carries by barcode scanner in successful situation, such information exchanging process is that information is to bar code to label to barcode scanner to information.
