Abstract

The invention discloses a multiplexing channel maintenance system capable of identifying channel faults on line, which comprises a protection device, a multiplexing device, power communication networkequipment, a channel monitoring device and a monitoring system, and is characterized in that the protection device is connected with an optical port of the channel monitoring device, and the opticalport of the channel monitoring device is connected with an optical port of the multiplexing device; and an electric port of the multiplexing device is connected with an electric port of the channel monitoring device, an electric port of the channel monitoring device is connected with the electric power communication network equipment, and the channel monitoring device is connected with the monitoring system through a communication line. The problem that in the prior art, the fault maintenance efficiency of a multiplexing channel is low is solved.

Description

technical field [0001] The invention relates to the technical field of substation relay protection communication, in particular to a multiplex channel maintenance system capable of identifying channel faults online. Background technique [0002] Optical fiber multiplexing channels play an important role in optical fiber longitudinal protection. Because it is not limited by distance, it is configured by the communication network and its safety is guaranteed, so it is widely used in power systems. In the field application process, there will be some abnormal problems in the optical fiber multiplexing channel, which will cause the channel to be blocked, but the maintenance process is relatively cumbersome. Monitor for easy troubleshooting. [0003] The current maintenance process mainly relies on the frame loss and error frame statistics of the protection device itself, the channel alarm and fault time records of the protection device, and the alarm lights of the multiplexing...
