A method for early war and disposal of optical cable risk in electric power communication network

Abstract

The invention discloses a method for early warning and disposal of optical cable risk in electric power communication network, in particular, the method comprises seven steps of establishing basic resource model, collecting equipment port performance data, calculating optical cable core attenuation, defining optical cable core attenuation reference value, performing early warning analysis of optical cable risk, disposing optical cable risk early warning list, and clearing early warning and insepcting. The invention has obvious beneficial effect and strong practicability, and greatly improvesthe operation and maintenance working level and the network operation quality.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a risk warning and treatment method for an optical cable in a power communication network. technical background [0002] The power communication network is another physical network of the company besides the power grid. It is an operation platform that carries various power information services, is the basis for the safe and stable operation of the primary system of the power grid, and is an important guarantee for the safe production of the State Grid Corporation. Among them, the optical cable is an important part of the power communication network, and is the basic resource for the power communication network to transmit and carry various business information. In recent years, with the continuous emergence and application of new technologies, the thinking of network operation and maintenance has gradually changed from passive fault repair to active identificat...

The former method relies heavily on the optical cable monitoring system. Generally, not all optical cables are deployed with an optical cable monitoring system. Manual lighting tests are time-consuming and laborious, so the investment cost for finding optical cable faults is relatively high.

The second method relies on the performance data collected by the network management system. The advantage is that the equipment at both ends of the optical cable is basically covered by the network management management and can provide basic judgment data as support. The receiving power establishes an absolute threshold value. The lower limit of the threshold value is the receiving sensitivity, and the upper limit is the overload point. If the threshold value is exceeded, an optical cable warning will be generated. There are two main disadvantages. One is the long-distance, The early warning thresholds of medium-distance and short-distance boards are different, and the workload of setting the maintenance thresholds is huge. Second, general equipment manufacturers have alarm indications when the receiving optical power of the port exceeds the limit, which has lost the purpose of early warning.
