Specific embodiment
The exemplary embodiment that the present invention will be described in more detail below with reference to accompanying drawings.Although showing the present invention in attached drawing
Exemplary embodiment, it being understood, however, that may be realized in various forms the present invention without should be by embodiments set forth here
It is limited.It is to be able to thoroughly understand the present invention on the contrary, providing these embodiments, and can be by the scope of the present invention
It is fully disclosed to those skilled in the art.
Embodiment one
As shown in Figure 1, the embodiment provides a kind of data processing methods, specifically includes the following steps:
Step S101: a line image dot array data is split as n group image point matrix data according to default injector configuration rule.
Wherein, above-mentioned line image dot array data is the line in the multi-thread image point matrix data received.Default nozzle
All nozzles are divided into multiple virtual rows in arrangement rule, and n is included multiple numbers of rows virtually arranged.That is, will own
Nozzle is divided into n virtual rows according to default injector configuration rule, and a line image dot array data is split as according to n virtual rows
N group image point matrix data.
As shown in Fig. 2, the present embodiment is illustrated so that nozzle is divided into 4 virtual rows as an example, 4 virtual rows are respectively using real
Heart circle, black triangle, filled square, solid five-pointed star indicate that the DPI of 4 virtual row's nozzles is 4 times of single row of nozzles,
So as to increase the DPI of nozzle.The line image dot array data T received is split as tetra- groups of image lattice numbers of A, B, C and D
According to, wherein corresponding one virtual row of one group of image point matrix data.
Step S102: by n group image point matrix data according in the first preset address rule write-in external memory.
Wherein, the data volume size of the first preset address rule and every group of image point matrix data in n group image point matrix data
And the value of n is related.External memory is initialized, after all memory spaces are assigned a value of zero, by the n of fractionation
Group image point matrix data is according in the corresponding address space of the first preset address rule write-in external memory.Due to external storage
The memory space of device is big, therefore writable a large amount of dot array datas.
Step S103: n group image point matrix data is read according to the sequence of addresses of external memory and is preset according to second
Address rule is written in internal storage.
Although the memory space of external memory is big, its read or write speed is slower, does not meet printing requirement of real-time, and interior
Although portion's memory memory space is smaller, its read or write speed quickly, meets printing requirement of real-time.Therefore implementation of the invention
The characteristics of example makes full use of external memory and internal storage is deposited outside the n group image point matrix data write-in after splitting
After reservoir, needs to be read according to the sequence of addresses of external memory and internal storage is written.Wherein, the second preset address
It is regular virtually arranged with every row in included number of nozzle it is related.
Step S104: n group image point matrix data is read according to the sequence of addresses of internal storage and is sent to nozzle.
Using the fast characteristic of internal storage reading speed, image point matrix data of the caching into internal storage is read
And it is sent to nozzle, so that nozzle ink jet printing is completed to the line image dot array data print job received.Circulating repetition
Above-mentioned steps S101 to S104 can realize the printing to the multi-thread image point matrix data received, by by multi-thread picture point
A line image dot array data in battle array data virtually discharges into capable fractionation according to fractionation, and is used cooperatively external memory and inside
Memory makes full use of the feature that external memory storage data quantity is big, internal memory data read operation processing speed is fast,
It improves image point matrix data and splits delay disposal speed.
Embodiment two
Above embodiments one simply describe data processing method of the invention, below will be based on embodiment one and specific
Application scenarios are described further explanation to it.
Specifically, as shown in figure 3, step S101 the following steps are included:
Step S301: according to the arrangement regulation of all nozzles in the x direction and the y direction, all nozzles are divided into n virtually
Row.
Wherein, X-direction is the direction perpendicular to page orientation, and Y-direction is page orientation, to all nozzles in X-direction and Y
The rule in direction is analyzed, and all nozzles is divided into n virtual rows, nozzle number and regular phase in each virtual row
Together.The Y-direction coordinate value of different spray nozzles in same virtual row is different, the different virtual Y-direction coordinates for arranging interior corresponding nozzle
The difference of value is identical, and each virtual row includes m nozzle, and m is positive integer.That is, the nozzle number in each virtual row is identical, all
It is m nozzle；The Y value of nozzle in virtual row is not all identical, but the difference phase in different virtual rows between corresponding nozzle Y value
Together, the corresponding nozzle in two virtual rows is identical along the distance of Y-direction.
Specifically, as shown in Fig. 2, all nozzles are divided into n virtual rows, the 1st nozzle each virtually arranged is in the side Y
To coordinate be respectively P1、P2…Pn.Wherein, the difference of the different virtual Y-direction coordinate values for arranging interior corresponding nozzle is identical, i.e.,
In first virtual row between first nozzle and second nozzle Y-direction coordinate value difference, be equal to first in other virtual rows
The difference of Y-direction coordinate value between a nozzle and second nozzle.The distance phase of corresponding nozzle in two virtual rows along Y-direction
Together, i.e., in the first virtual row first jet and the Y-direction coordinate value of first jet in the second virtual row difference, be equal to the first void
The difference of second nozzle and the Y-direction coordinate value of second nozzle in the second virtual row in quasi- row, that is to say, that adjacent virtual was arranged
Postpone identical.
By taking 4 virtual row's nozzles as an example, 4 rows virtually arrange respectively using solid circles A, filled square B, black triangle C,
Solid five-pointed star D indicates, 4 rows virtually arrange in the coordinate value of first nozzle respectively arranging in Y-axis be followed successively by 1,3,7,9.4 rows are empty
The DPI of the nozzle of quasi- row is 4 times of single row of nozzles.To can be seen that the DPI of nozzle is increased.Wherein, the second spray virtually arranged
The nozzle (solid circular pattern expression) that mouth (expression of black triangle pattern) is virtually arranged relative to first needs to postpone 2 lines and beats
Print；Nozzle (the solid circular pattern table that the nozzle (expression of filled square pattern) that third is virtually arranged virtually is arranged relative to first
Show) need to postpone the printing of 6 lines；The nozzle that 4th nozzle (solid five-pointed star pattern indicates) virtually arranged virtually is arranged relative to first
(solid circular pattern expression) needs to postpone the printing of 8 lines.
