Dual-computer control switching system with monitoring function

The invention discloses a dual-computer control switching system with a monitoring function, which not only can monitor the connection state in real time, but also can more efficiently locate a fault position when a fault occurs by monitoring the connection state between a sending end and a calculation end and between a receiving end and external equipment, thereby improving the fault processing efficiency and reducing the fault processing cost. Moreover, the optical power is monitored at the transmitting end and the receiving end, and the normal processing of the service is not affected in the monitoring process, thereby guaranteeing the operation efficiency of the equipment. 本发明公开了一种具有监测功能的双机控制切换系统，通过在发送端与计算之间、接收端与外接设备之间进行连接状态的监测，不仅可以实时监测连接状态，还能够在发生故障时，更为高效的定位故障位置，从而提升故障处理效率，并且在发送端与接收端分别进行光功率的监测，监测过程中不影响业务的正常处理，从而保障设备的运行效率。
