【摘要】 为了提高大型喷绘机的打印速度和打印精度,设计了双CPU结构的嵌入式喷绘机控制系统。控制系统采用韩国ADC公司的Jupiter32位嵌入式微控制器作为嵌入式控制单元,形成双CPU结构,其中,一个CPU专门用于100Mb/s以太网传输打印数据,另一个CPU通过高速DMA控制器将数据高速送往喷头,实现高速打印,由缓存器FIFO实现两个CPU系统之间的数据交换。控制系统软件是在μClinux操作系统环境下开发完成的。控制系统在喷绘机使用360DPI高精度喷头时满足了大数据量快速传输,实现了喷绘机的高速高精度打印。更多还原

【Abstract】 Inkjet printer control system with an embedded dual CPU structure is designed to improve the printing velocity and precision. The system has two CPUs. One is used to transmit printing data by 100 Mbp/s ethernet bus, the other is adopted to transfer high speed data to print head by DMA. Both are 32 bits Jupiter embedded micro-controller of ADC company. The data exchanging of two CPUs is accomplished by FIFO. The software develop is completed under the μClinux operation system. The system can realize high speed transmission of data stream and printing with high velocity and precision when print head with 360DPI precision is used.更多还原
