摘　　要：针对喷射打印过程中微喷装置各子系统协调工作的要求,设计了以LABVIEW软件平台与STM32微控制器为核心的气动式微滴喷射控制系统,实现喷射过程的图像采集,PC机与STM32微控制系统的串行通信及协调喷射打印沉积.在上述基础上,进行CCD相机延时触发微滴成形过程图像采集及阵列沉积实验.结果证明,此控制系统实现了微滴成形过程动态图像采集;在PET膜上打印成形预设字符微滴阵列,表明所设计的控制系统各功能模块间能协调工作.According to the coordination requirement of each subsystem during the micro-droplet generation, the control system for pneumatic driven micro-droplet jetting generator was designed based on the software-platform of LABVIEW and STM32 micro-controller system. This system achieves the aehquisition of the jet process images,the serial communication between PC and STM32 micro-control system,and coordinated jet printing deposition process.Through the ecquired images and the experiment of array deposition, it is proved that the system realizes the dynamic image acquisition of the droplet forming process, and the printing of the preset character droplet array on the PET film. Besides, each function module is in coordination with another in the control system.
