摘　　要：针对目前立体光固化(SLA)快速成型控制系统开发难度及成本较高、体积庞大等问题,设计了一种便携式快速成型控制系统OL-SLA。以ARM Cortex-M4内核的Kinetis系列微控制器K60为核心,移植嵌入式操作系统MQX,使其具有实时性高、快速中断响应等特点;使用多种传感器进行数据采集,结合嵌入式文件系统FATFS和PID算法,实现了系统脱机运行和闭环控制,提高了成型精度。实验表明,该系统工作稳定,成型精度高,适用于中小型企业进行快速产品验证。In order to overcome the difficulties in developments,high cost and larger volume of the SLA rapid prototyping control system,a portable rapid prototype control system OL-SLA based on ARM processor is proposed.Using K60 which is a Kinetis family MCU based on Cortex-M4 launched by Freescale as control chip and porting embedded operating system MQX to get high timeliness and fast interrupt response.To meet the requirements of offline work,closed-loop control and precision improvement,a variety of sensors are used to collect data,embedded file system FATFS and PID algorithm are combined.Experimental results show that the system is stable,high precision in molding and is suitable for small and medium enterprises in rapid product validation.
