摘要
为解决目前细胞注射装置普遍采用的在显微镜下手动操作的机构效率低下、响应速度慢等问题,提出了基于DSP和ARM嵌入式系统的细胞注射装置。该装置利用基于TMS320DM642的图像处理子系统完成图像的采集、处理并将处理的结果保存在特定的存储器内;同时,基于S3C2410的控制子系统完成人机交互、宏/微双精度微动台控制等功能,并利用TMS320DM642的HPI接口进行DSP与ARM处理器的数据交互。模拟结果表明,系统控制自动定位精度达到0.1μm,提高了系统运动精度,图像处理速度达到11 frame/s。
In order to improve the low efficiency and the low velocity of common cell injection device in manual operation machine at present, a cell injection device based on DSP and ARM was presented. An image processing subsystem based on TMS320DM642 was used to accomplish image sampling and processing, and the results were stored to a special RAM. The control subsystem based on S3C2410 was designed to have man-machine conversation and control macro-micro dual-drive table, and the HPI interface of TMS320DM642 was utilitied to transfer data between DSP and ARM. The experimental results indicate that the positioning precision of the system is 1 μm, which improves the motion precision of the system, and obtains the velocity of image processing of 11 frame/s.
