The problems in the electric energy management system, such as real-time communication and networking, can be effectively solved through embedded communication manager. In this paper, the framework of the electric energy management system instituted by embedded communication manager was analyzed, and the scheme of the communication manager based on MPC860T processor and Nucleus PLUS operating system platform was proposed. Moreover, the principles of hardware system and software design were specially introduced. Finally, the electric energy management system based on communication manager was proven applicable through testing.
