摘　　要：由于远动系统信道配置的适应性难以满足客观应用需求,导致铁路电力远动系统数据包传输时间较长,控制效果不佳。为此,提出基于光纤通信技术的铁路电力远动系统控制方法研究。以远动系统中的信道为研究对象,设计局部操作网络(LocalOperating Network,LON)现场总线布局后,结合光纤通信技术对远动系统传输进行控制。经实验证明,利用该方法对远动系统进行控制后,数据包的传输时间为0.2~0.8 s,传输时间可始终保持在1 s以下,说明利用该方法对铁路电力远动系统控制的效果较好。Due to the difficulty in meeting the objective application requirements due to the adaptability of the channel configuration of the remote control system,the transmission time of data packets in the railway power remote control system is long,and the control effect is poor.Therefore,a research on the control method of the railway power remote control system based on fiber optic communication technology is proposed.Taking the channel in the remote control system as the research object,a Local Operating Network(LON)fieldbus layout was designed and combined with fiber optic communication technology to control the transmission of the remote control system.Experimental results have shown that after using the method proposed in this article to control the remote control system,the transmission time of the data packet is 0.2~0.8 s,and the transmission time can always be kept below 1 s,indicating that the method proposed in this article has a good control effect on the railway power remote control system.
