Abstract
The present invention discloses a method for restoring a print signal of a POS machine in the retail industry into a graphic file. The method is characterized by comprising the following steps of: 101, a computing device which is provided with applications and has data processing and storage functions is connected to a print output port of the POS machine of a merchant; 102, the computing device acquires the print signal output to a printer by the POS machine of the merchant, wherein the print signal comprises a printer control instruction, a graph printing instruction and a mode of splicing N sub-graphs into a complete graph; and 103, a computing device block searches for a print control instruction set characters in a self-carried database, carries out character comparison between the print control instruction set characters and the acquired print signal, filters and cancels the printer control instruction appearing in the print signal from the print control instruction set character and reserving the graph print instruction and the mode of splicing the N sub-graphs into the complete graph. According to the method for restoring the print signal of the POS machine in the retail industry into the graphic file, starting from the exterior of the POS, i.e. print data, complex technical connection to a POS system is not required, and meanwhile, the hidden danger of invading of the system to the POS is avoided.
Description
Technical field
The present invention relates to field of computer technology, especially relate to a kind of method retail trade POS print signal being reduced into graphic file.
Background technology
" large data ", as vocabulary burning the hotest at present, have a large amount of application at industry-by-industry.Thing followed data warehouse, data security, data analysis, data mining etc. become around the utilization of the commercial value of large data the profit focus that industry personage falls over each other to pursue gradually." large data " very important basis is exactly reliable Data Source, i.e. the collection of raw data.
Retail service industry on line, all consumption datas are all stored by server, for analyzing in the future.But online lower retail service industry, sales data, as the amount of money of sale, single product of sale, classification etc. is generally all kept in POS (computing machine) system of retailer.Allow these data for the application of the outside of POS, as: marketing activity, member system etc., then need complicated system docking, and have potential risks hidden danger, as: the data from outside are stolen, and distort.So the consumption data at present under line, especially cash sales, that still can not carry out unifying gathers and accurate analysis.
Summary of the invention
Object of the present invention is exactly the outside from POS, namely starts with from print data, retail trade POS print signal is reduced into graphic file, and analyzes, and reaches the risk hidden danger reducing POS system.
Retail trade POS print signal is reduced into a method for graphic file, it is characterized in that, comprise the following steps:
101, the computing equipment of data processing and memory function that has that application program is housed is connected with the printout mouth of businessman POS;
102, computing equipment obtains the businessman POS print signal to printer output, the mode that this print signal comprises printer control instruction, graphic printing instruction, N number of spirte are spliced into full graphics;
103, computing equipment block searches the Print Control instruction set character carried in database, and carry out character comparison with the print signal obtained, therefrom filter and delete the printer control instruction appeared in this print signal, reservation graphic printing instruction and N number of spirte are spliced into the mode of full graphics;
104, computing equipment identifies graphic printing instruction, and single subgraph print command is a description, and namely providing transverse and longitudinal coordinate in two dimensional surface is whether certain position of (X, Y) prints;
105, whether corresponding coordinate prints to preserve and forms dot array data by computing equipment, if this position prints, then the value of this position is 1; If this position does not print, then the value of this position is 0;
106, computing equipment repeats step 105 to N number of subgraph, forms the graphic file of N number of subgraph;
107, the computing equipment mode that utilizes N number of spirte to be spliced into full graphics is spliced into a complete large figure N number of subgraph;
108, large figure is added bitmap images header by computing equipment, specifically comprises document size, size and resolution, can generate final graphic file.
Described step 107 comprises the following steps:
201, computing equipment obtains N number of spirte in print signal and is spliced into the mode of full graphics;
If 202 connecting methods are in same coordinates regional, repeatedly print twice, then the subgraph file of twice printing is done ' position or ' computing at same coordinate position, generate last complete large figure;
If 203 connecting methods are have newline after subgraph, then the upper left position arranging the subgraph after newline is: horizontal ordinate: the upper left corner horizontal ordinate of the subgraph before newline, ordinate: the ordinate+1 in the subgraph lower left corner before newline;
If 204 identify without any splicing, then give tacit consent to and vertically continue to print under subgraph.
Concrete, the computing equipment described in the present invention can adopt known schemes of the prior art, and relevant above-mentioned known solution, those skilled in the art understands all, does not repeat them here.
Effect of the present invention is actively significantly: the present invention is from the outside of POS, namely print data is started with, without the need to carrying out complicated interface differential technique with POS system, also stopped the hidden danger that system invades to POS simultaneously, because data stream is unidirectional during printout, can only be POS to printer output, printer cannot write data by print.er port to POS.
