摘　　要：针对灰度微滴喷射技术中传输数据量大和传输数据不匹配的问题,对灰度微滴喷射的技术特点进行了分析,对灰度微滴喷射技术的控制方法进行了归纳,提出了一种基于ARM+FPGA系统架构和双口RAM乒乓操作技术的灰度微滴喷射控制系统,采用Modelsim软件对FPGA内部模块进行了时序仿真,利用搭建的灰度微滴喷射实验平台对灰度色阶和边缘锯齿进行了测试。实验结果表明,该系统能够实现最大幅面为280 mm且具有8个灰度等级的微滴喷射,打印的图像边缘锐利清晰无明显锯齿。Aiming at the problems of big data to process and transmission rate mismatch in gray micro-droplet jetting technology,after the analyse of the characteristics and control method of grayscale micro-droplet jetting technology,a gary micro-droplet jetting control system base on ARM and FPGA architecture and dual port RAM ping-pang operating technology was presented. The timing simulation of FPGA internal module was established based on Modelsim software. The gray levels and edages swatooth were tested on the gray microdroplet jetting experiment platform.The results indicate that the system can achieve the maximum width of 280 mm and 8 grayscale microdroplet jetting and the printed image edges are sharp and clear with no obvious swatooth.
