Example 1
Referring to fig. 1, an embodiment of the present invention provides a tandem printing method, which is applied to a scene in tandem printing in a pass. In the method, in the process of printing a pass, the upper computer only needs to send the data of one continuous sunning unit in the pass to the lower computer at one time and write the data into the memory of the lower computer. And then repeatedly reading and printing the stored image data of the continuous printing unit by the lower computer in a pass printing process according to the printing parameters so as to finish continuous printing of the pass. According to the scheme, the upper computer and the lower computer are matched for writing and reading of the printing data, and the continuous exposure of the images in one pass is processed by the lower computer such as an FPGA, so that the continuous exposure printing of each pass is realized, and the upper computer only needs to send data once and only needs to send data of one continuous exposure unit. Therefore, the data processing amount and the data transmission amount of the upper computer can be remarkably reduced; the data processing speed and the communication transmission efficiency of the upper computer are improved, and meanwhile, the data processing complexity of the upper computer is reduced. Thus, the upper computer can allocate more resources to process the printing operation of the rest of the printing equipment, thereby improving the printing efficiency of the whole printer system.
As shown in fig. 1, the method specifically includes the following steps:
s1, receiving printing data and printing parameters of a continuous sunning unit which are transmitted by an upper computer and printed by a current pass;
The whole printing flow is controlled by an upper computer, and the upper computer sends the data of the next pass to a lower computer between two pass printing, wherein the lower computer can be an FPGA. When the data is organized in the channel sequence of the pass scanning direction and the current pass continuous sunning printing starts, the upper computer sends the printing data of one continuous sunning unit of the current pass to the lower computer. The length of the transmitted print data is the length of the print data of one continuous printing unit. The length of the print data is determined by the pass width and the continuous exposure unit width. The length value of the print data is fixed for one print job. The data sent by the upper computer is organized according to the channel sequence of the pass scanning direction. The lower computer is responsible for receiving the printing data and the printing parameters of a continuous sunning unit sent by the upper computer.
S2, writing the printing data of the continuous sunning unit into a memory;
After the lower computer receives the printing data of the continuous sunning unit sent by the upper computer, the printing data can be stored in the memory according to the sequence of data receiving.
S3, circularly reading the printing data of the continuous sunning unit from the memory in a pass printing process according to the printing parameters;
And the upper computer controls the printing equipment to drive the spray head to move to the printing position according to the initial printing position configured by the printing parameters to start printing of the current pass. In the printing process, the lower computer such as an FPGA repeatedly reads the continuous sun-curing data stored in the memory according to the printing process.
As shown in fig. 2, the printing parameters received by the lower computer include the data volume of a pass printing and the data volume of a continuous sunning unit. The specific steps of circularly reading the printing data of the continuous sun unit from the memory in the pass printing process according to the printing parameters include:
s31, acquiring the initial position of printing data of the continuous sunning unit in a memory;
The starting position of the printing data of the continuous sun unit in the memory can be recorded when the continuous sun unit is stored in the memory of the lower computer.
S32, determining the residual printing data quantity according to the current printing pixel position and a pass printing data quantity;
The position of the current print pixel refers to what pixel the current print is the current scan print. The printing device will record what pixel is currently being printed during printing. According to the position of the pixel which is printed currently, the number of the pixels which are printed can be obtained, so that the data quantity which is printed is obtained, and the data quantity which is not printed in a pass can be obtained by combining the data quantity which is printed in the pass.
S33, determining the data quantity read at this time according to the residual data quantity and the data quantity of one continuous sunning unit;
The method for determining the data quantity read at this time comprises the following steps: if the residual data volume is greater than or equal to the data volume of one continuous sunning unit, the data volume read at this time is the data volume of one continuous sunning unit;
If the residual data volume is smaller than the data volume of one continuous sunning unit, the data volume read at this time is the residual data volume.
S34, reading the printing data of the continuous sunning unit according to the initial position and the data quantity read at the time;
Since the print data size of a pass may or may not be an integer multiple of the data size of a tandem sun unit. If the number is an integer multiple, the data size of each read continuous sunning unit in the printing of a pass is just the total data size of a complete continuous sunning unit. If the data is not an integer multiple, the data of the last continuous sunning unit read is smaller than the data of one continuous sunning unit. Therefore, when each print data of one continuous printing is read, the data quantity of the remaining unprinted data in a pass is judged to be insufficient to be the data quantity of a complete continuous printing unit. If so, the printing data of the data quantity of one continuous sunning unit is read, and if not, the printing data is read according to the residual data quantity. When the starting position and the data quantity read at this time are determined, the data of the continuous sunning unit can be read from the starting position of the continuous sunning unit data storage.
S35, judging whether the print data of a pass is read, if yes, ending the reading of the data, otherwise, repeating the steps S32 to S35.
After the printing of the data of one continuous sunning unit is finished, the pointer for reading the memory data returns to the initial position of the data storage of the continuous sunning unit, and the continuous sunning unit is repeatedly read until the data of the data quantity of a pass is read.
S4, performing eclosion treatment on the read printing data and then sending the printing data to a spray head for printing.
The lower computer performs eclosion treatment on the read printing data, distributes the data to the spray head according to the channel length, and prints the printing data by the spray head.
As shown in fig. 3, the specific steps of performing eclosion processing on the read printing data and then sending the data to a spray head for printing include;
s41, receiving an eclosion template printed by a pass sent by an upper computer;
the upper computer maintains an eclosion template with the same width as the pass width according to the pass width, namely the data length of the eclosion template is equal to the data length of the pass printing data. And the upper computer sends the computed eclosion template to the lower computer.
S42, obtaining a channel offset value corresponding to the currently read printing data and the position of the printing data in a channel;
While reading the print data, the lower computer determines to which channel the data corresponds by the count value and the channel length parameter, and precisely counts the position of the data in the corresponding channel.
Because the lower computer, such as the FPGA, distributes the data accessed from the lower computer to different channels according to the channel sequence, the width of a data bus used by the FPGA for sending to the spray head is limited, and 4 bytes or 8 bytes are taken at a time, so that one channel can acquire complete channel data only by a plurality of clock cycles, and the position of the data to be distributed currently in the channel is determined by the counter.
S43, obtaining a sub-template for eclosing the printing data from an eclosion template printed by a pass according to a channel offset value corresponding to the printing data and the position of the printing data in a channel;
The eclosion operation of the data and a portion of the eclosion template can be determined from the channel offset and the relative position of the data in the channel, the portion being a sub-template that eclosion the data, so that the sub-template is the portion of the eclosion template corresponding to the data.
S44, the sub-template is utilized to carry out eclosion treatment on the printing data, and the printing data is sent to a spray head for printing.

Wherein the lower computer may be an FPGA. When the data is organized in the channel sequence of the pass scanning direction and the current pass continuous sunning printing starts, the upper computer sends the printing data of one continuous sunning unit of the current pass to the lower computer. The length of the transmitted print data is the length of the print data of one continuous printing unit. The length of the print data is determined by the pass width and the continuous exposure unit width. The length value of the print data is fixed for one print job. The data sent by the upper computer is organized according to the channel sequence of the pass scanning direction.
