摘要
在分析研究了便携式仪器装置控制系统的特点及要求后,采用基于ARM最新Codex-M3内核的STM32F103作为主控芯片,移植μC/OS-Ⅱ嵌入式操作系统作为整体设计方案,重点分析了如何通过采用实时操作系统编程的方法实现仪器所有系统功能。该方案应用于某种便携式射线源,采用分任务、分模块设计思路,实现关键数据采集、存储,工作参数可调,驱动相位自动调整,按键,LCD显示,RS-485通信等系统功能。应用实验结果证明,在便携式仪器设计中采用微控制器操作系统是一种很好的选择。
Having been analyzing and researching the features and requirements of portable instruments, the design scheme based on latest Codex-M3 of ARM as the core and tiansplanted μC/OS-II embedded operating system is proposed. The implementation of all the functions by adopting the method of system programming based on RTOS is analyzed emphatically. The scheme is applied in certain portable X-ray source; the system functions including data collection and storage, adjustable working parameters, driving phase automatic adjustment, keypad, LCD display, RS-485 communication, etc. , are implemented through the design concept of multitasking and modularization. The experimental results show that using MCU and μC/OS-Ⅱ operating system is a better choice in designing portable instruments.
