【Abstract】 μC/OS-II is the kernel of a source-code publicized real-time operating system and is portable, reliable and stable. A μC/OS-II based embedded protection device for generator is presented and the necessity and application value of leading real-time operating system into microcomputer based relaying protection is illuminated. On the basis of explating μC/OS-II to digital signal processing (DSP) chip TMS320VC33, the μC/OS-II is integrated with high performance floating point DSP chip, then according to the protection principle the protective scheme of the presented protection device, whose multi-functions are implemented by dividing different tasks, is proposed. Test results of the presented protection device show that the embedded generator protection device using μC/OS-II is reliable, flexible and easy to maintain.更多还原
