电力系统中MEMS光开关切换路径优化控制的方法

针对电力系统中微机电系统(MEMS)光开关在切换备纤时可能受到光控信号的影响而造成光时域反射仪(OTDR)发生损坏的问题,文章提出了一种电力系统中MEMS光开关切换路径优化控制的方法,在对MEMS光开关进行完整的扫描后得到其精确的光信号通道功率等高图,然后再对其切换路径进行优化控制,使得MEMS光开关可以在平衡控制通道切换时间的前提下使入射光沿相对通道隔离度最高的最佳路径进行切换控制,同时也可以在保证切换时间的前提下将MEMS光开关在切换时对其他通道的影响降到最低,并且即使在通道环境非常复杂的情况下也不受影响。

A Method for MEMS Optical Switches in Power Systems

The Micro-Electromechanical System(MEMS)optical switches in power systems may be affected by optical control signals during fiber switching,which may cause damage to Optical Time-Domain Reflectometer(OTDR).In order to solve this problem,this paper proposes a method to optimize the switching path of MEMS optical switches in power systems.After the optical switch performing a complete scan,the accurate optical signal channel power contour map is obtained,and then the switching path is optimized and controlled.Therefore,the MEMS optical switch can achieve the highest relative channel isolation of incident light along the premise of balancing the control channel switching time.The best path for switching control can also be used to minimize the impact of the MEMS optical switch on other channels when switching under the premise of ensuring the switching time,and it will not be affected even in a very complicated channel environment.
