An Electric Power System Protocol Conversion Method Based on Embedded Platform

In the electric power systems, there are many different types of equipment with a variety of different functions. They need to communicate with each other through all kinds of hardware interfaces and software protocols. With the construction of electric power data network and the improvement of automation, remote control system in general will be replaced by dispatching automation system, which merges with computer, protection, control, communication network and other technology. And all kinds of information collect systems will also plug into it. However, there are many kinds of interfaces and protocols used in the collection of information. There is no uniform standard for all kinds of communication, which hinders the interconnection between systems and devices. Protocol conversion technology is an important method to solve this problem. In this paper, we present a new protocol conversion method based on embedded platform. Our method provides a modular function for setting up all kinds of communication interfaces; provides another modular function for all kinds of communication protocols; and provides interactions with the two modules. Our method has been successfully applied to a number of electric power monitoring systems, which proves the practicability of it. Keywords-electric power system; protocol conversion; embedded platform
