摘　　要：针对现有电力智能设备远程软件升级方法的不足,提供一种智能电力设备在线远程软件升级新方法,采用无应答机制和历史断点续传技术,避免了升级链接中断、通信故障等导致的反复下发升级数据文件、设备更新程序占用系统主站资源等问题,提高了数据远程传输的高效性和准确性。实践应用证明,文中提出的方法具有升级效率高、升级速度快和升级灵活性好等特点,非常适用于终端设备多、升级文件大、环境复杂的电力系统。Aiming at shortcomings of the existed methods, a new method of program remote on-line updating for intelligent electrical power equipments was proposed, with using the non-response mechanisms and historical break point continue transmission technology to avoid repeatedly sending updating data files caused by link disruption or communication failures, and the main station system resources occupied by updating program, so then the efficiency and accuracy of data remote transmission was improved. Practice had proved that the proposed method had the characteristics of high updating efficiency, updating speed and good updating flexibility, and was very applicable to the power system of many terminal equipments, large updating data files and complex environment.
