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
