With the rapid development of mobile network technology

mobile terminal application of plant-level supervisory information system(SIS) for power plant has a broad prospect. To meet the specific application requirements of mobile terminal in power plant

the network structure and data transmission scheme are designed by using Tencent Wechat as mobile terminal platform. Combined with power plant application examples

the main functions of the mobile terminal application are described in detail

some problems of mobile terminal application in the development of the power plant information are discussed

and the mobile terminal application is explored in the future of the power plant. This study designs a safe and reasonable data transmission scheme to realize the share of production data on the Internet

and develops a richer production monitoring function at the mobile terminal to meet the mobile terminal requirements of SIS function in the power plant. In general

this study provides the reference for the application of mobile information technology in power plants.
