摘要/Abstract

摘要：

针对供电综保数据采集处理系统多任务、实时可靠的需求,文中结合M3内核芯片,利用μC/OS-Ⅲ实时操作系统进行供电综保数据采集处理系统设计。通过对数据采集处理系统功能分析,将系统划分为5个优先级不同的任务,根据应用任务特点及需求进行了操作系统的规划设计,通过信号量和事件标志组实现了任务同步,通过消息队列和互斥型信号量实现了任务通信与资源管理。使用μC/Probe对系统运行进行检测,应用任务堆栈利用率均小于70%,CPU利用率为52.35%,中断关闭时间最高为3.31 ms,验证了该系统能够实时可靠运行。

Abstract:

Aiming at the demand of multitask, real-time and reliable operation of the data acquisition and processing system of power supply integrated protector, combined with the M3 core chip,using μC/OS-III real-time operating system to design the data acquisition and processing system of power supply integrated protector. By analyzing the functions of the data acquisition and processing system, the system was divided into five tasks with different priorities,the planning and design of the operating system was based on the characteristics and requirements of the application tasks, task synchronization was realized by semaphores and event flag groups, task communication and resource sharing were realized through message queues and mutex semaphore. System operation was detected using μC/Probe, the application tasks Stack Usage was less than 70%, the CPU Usage was 52.35% ,and the Interrupt Disable Time was up to 3.31 ms, verified that the system could run reliably in real time。

Key words: data acquisition and processing, M3 chip, μC/OS-Ⅲ real-time operating system, multitasking, operation management, μC/Probe detection
