摘　　要：随着科技的发展,电力系统中智能设备的应用场景也变得越来越多,特别是在电力自动化控制和数据采集通信方面,很多设备平台都采用基于嵌入式的Linux操作系统,以远方电能量数据终端(ERTU)为例,因为其运行过程中需要与各种电能表通信,又需要支持不同主站系统的数据召唤,所以各类通信参数就需要以配置文件的形式预置到设备中,如果设备发生故障,后续恢复过程中配置文件可能就需要进行重新配置,不但增加工作量,而且参数前后一致性也会存在问题.如果利用Linux系统下的脚本程序和外接存储器,简单快捷的实现配置文件的自动备份与还原,那么就可以节省现场工程运维工作量,提升整个工程应用的管理水平.Amid the progress in science and technology,the application scenarios of intelligent devices in a power system have been increasing,especially in power automation as well as data acquisition and communication.Many platforms rely on an embedded Linux operating system.An Energy Remote Terminal Unit(ERTU)is taken as an example for analysis.Communication parameters should be preset into the device in the form of configuration files,since ERTU needs to communicate with electric energy meters and supports data calling of different master station systems during operation.If the device fails,the configuration files may require reconfiguration in the subsequent recovery process,increasing the workload and affecting the consistency of parameters.If the automatic backup and restore of configuration files are realized simply and quickly with the script program and external memory in a Linux system,then the workload of field engineering operation and maintenance can be reduced,improving the management level of the whole engineering application.
