摘　　要：针对电力线空气开关远程控制中鲁棒性差的问题,提出一种电力线空气开关信号鲁棒传输与控制方法。利用电力线载波通信技术对空气开关的远程传输模块进行优化,通过继电器模块、载波通信模块、显示模块、开关动作模块和摄像头模块之间的协调配合,增强抗电磁干扰能力,提升硬件控制过程的鲁棒性。采用RSA算法确定空气开关信息素数,根据信息加密和密钥参数建立电力线载波空气开关远程通信协议,防止空气开关误操作和远程信号入侵,提升了控制信号鲁棒性。实验结果表明,应用该方法的控制信号抗干扰效果较好;触头压力较为稳定,为350 N;防误操作效率较高,为97%。控制鲁棒性增强。Aiming at the problem of poor robustness in remote control of power line air switch,a robust transmission and control method of power line air switch signal is proposed.The power line carrier communication technology is used to optimize the remote trans-mission module of air switch.Through the coordination among relay module,carrier communication module,display module,switch action module and camera module,the anti-electromagnetic interference ability is enhanced and the robustness of hard-ware control process is improved.RSA algorithm is used to determine the prime number of air switch information,and the long-distance communication protocol of power line carrier air switch is established according to information encryption and key parameters,which can prevent air switch misoperation and long-distance signal intrusion and improve the robustness of control signal.The experimental results show that the anti-interference effect of the control signal using this method is good.The contact pressure is stable,350 N.The misoperation prevention efficiency is 97%.Control robustness is enhanced.
