一种基于装置打印接口的保护动作信息远传终端设计

A Protection Device Action Information Remote Transmitting Terminal Based on Printing Interface

本文开发设计了一套电力系统继电保护装置动作信息远传系统。该系统包括将继电保护装置打印接口从RS232转换为以太网的转换器,汇总继电保护装置打印数据的交换机,汇总储存的数据库服务器,以及远程查看数据库服务器的远传终端。运用本系统,能够在终端远程查看继电保护装置的保护动作信息,实现对保护动作信息的存储、远程查看和远程打印。

This paper proposes an action information remote transmitting system for relay protection device of power system, including a converter for converting a relay protection device printing interface from RS232 to Ethemet, a switch for summarizing the printing data of relay protection device, a database server for summarizing and storing, and a remote terminal for remote access to the database server. With this system, the protection action information of the relay protection device can be remotely accessed at the terminal, realizing the storage of the protection action in- formation, remote access and remote printing.
