| Abstract: | In accordance with the operational requirements of the robots for 3D inkjet plotting,the control system based on FPGA for large sized 3D true color inkjet has been designed.With the PowerPC405 hard kernel that is embedded in Virtex-II Pro FPGA as the core,the multiple-task real-time processing platform is established by transplanting Xilkernel embedded operating system and Lightweight IP(LwIP) network protocol.In addition,in order to satisfy the inkjet printing head control sequence,the IP core and related drive are designed,and the hardware co-acceleration unit is setup;the inkjet process is executed under the rhythm of the position trigger signal.The test result indicates that the system owns strong flexibility,good real-time performance,and is able to accurately carry out 3D true color inkjet plotting in high speed. |
