In order to better understand the technical solution, the technical solution will be described in detail with reference to the drawings and the specific embodiments.

As shown in fig. 1, the inkjet printing control system provided by the embodiment of the present invention includes an MCU unit 10, an FPGA unit 20, an SDRAM storage unit 30, and a driving unit 40.

The MCU unit 10 is used for receiving or sending jet printing data; the FPGA unit 20 is connected with the MCU unit 10, and the FPGA unit 20 is used for receiving the jet printing data sent by the MCU unit 10 and converting the jet printing data into a level control signal; the SDRAM storage unit 30 is connected with the FPGA unit 20, and the SDRAM storage unit 30 is used for storing jet printing data; the driving unit 40 is connected to the FPGA unit 20 to drive the ink cartridge to perform the inkjet printing according to the level control signal.

It should be noted that, the SDRAM storage unit 30 is used as a storage unit of the inkjet printing data and can store the inkjet printing data converted in advance by a plurality of consoles, so that by connecting the FPGA unit with the MCU unit and connecting the SDRAM storage unit with the FPGA unit, it is possible to read the next data from the SDRAM storage unit 30 when the next inkjet printing process is started after one inkjet printing data is completed, and it is not necessary to obtain the inkjet printing data from the console, so that the console has enough time to convert, thereby avoiding the situation that the line speed is too fast to generate and the inkjet printing data is not transmitted timely, and ensuring the continuity and integrity of the inkjet printing process.

As one embodiment, as shown in fig. 2, the MCU unit 10 is connected with the console 50 through a data transmission line to receive the jet printing data.

It should be noted that the data transmission line may be a USB transmission line, which is not limited in this embodiment of the present invention.

As one embodiment, the MCU unit is connected with the FPGA unit through a data bus so as to transmit interrupt signals and data.

As one embodiment, the driving unit 40 is implemented by a level conversion chip.

That is, level conversion is performed by the level conversion chip so as to provide a level required for driving to the ink cartridge ejection head.

As a specific embodiment, the console 50 sends the jet printing data to the FPGA unit 20 through the MCU unit 10; the FPGA unit 20 stores the received jet printing data into an SDRAM storage unit 30; when the ink box nozzle needs to jet print data, the FPGA unit 20 reads the jet print data from the SDRAM storage unit 30, converts the jet print data into high and low level control signals, and drives the level conversion chip, so that the level conversion chip directly drives the ink box to jet ink; until a stroke of data is printed; after a data jet printing is completed, the FPGA unit 20 sends an interrupt signal to the MCU unit 10 to continue the data transmission process.

It should be noted that, the console 50 can convert n inkjet printing data in advance, for example, 50 inkjet printing data, send 50 inkjet printing data to the FPGA unit 20 through the MCU unit 10, the FPGA unit 20 stores the received inkjet printing data into the SDRAM storage unit 30, and when the next inkjet printing process is started after one data is inkjet printed, the next data can be read from the SDRAM storage unit 30, so as to avoid the situation that the production line speed is too fast and the inkjet printing data is not transmitted in time, and ensure the continuity and integrity of the inkjet printing process.
