This paper introduces firstly the analog signal energy meter and a pure digital power meter integrated into the architecture of a Measurement system, and analysis of the realization of the measurement system in embedded real-time operating system uCOS-II environment and include: the division of tasks communication and data sharing issues between tasks, which focus on the problem of communication data sharing between tasks. Concluded the overall inter-task communication situation, and laid a solid foundation for the design of a high-precision digital power meter measurement software.
