Abstract：The Hierarchical Distributed RTU remote device is a remote monitoring and control devices unit, responsible for the signal to the on-site, industrial equipment monitoring and control. With the commonly used compared to the PLC, RTU usually have excellent communication capabilities and greater storage capacity for even worse temperature and humidity environment, to provide more computing power. It is with this series of advantages, so many in the field of application of this technology, and achieved remarkable results. With the computer technology and the increasing popularity of embedded information processing technology, the rapid development of remote systems for the increased demands, the paper distributed to the remote RTU device to study, first of all, analysis of the merits of distributed architecture, In this paper, based on the design of the structure of the traction substation, traction substation on the structure, functions, features for a more detailed analysis, and then use the gateway to the communication protocol introduced with the stated focus of the final design of the study and The structure of the switch communications hardware and software.
