This paper demonstrates the lately developing technology-Smart Grid. Compared with the traditional way of trunked communication system in emergency, this paper proposed a more efficient method to solve this problem to use smart meter installed in the ubiquitous power line. Hence, this paper is proposed a network system, giving a method to communicate and control when accidents happening under many circumstances. The structure of the network system, the group calling method and the singling structure are all demonstrated to present the integrated network.
