The method comprises the following steps: firstly, analyzing the parameter indexes influencing the optical fiber reliability environment; then, acquiring accurate and reliable data through experiments; establishing an optical fiber fault model and an optical fiber ageing prediction model by utilizing the regression analysis method, wherein the experiment is mainly divided into two parts, namely, a splice loss experiment and a non-splice loss experiment; the splice loss experiment mainly comprises a fusion loss experiment and a connector loss experiment; the non-splice loss experiment mainly comprises a bend loss experiment, a temperature-humidity circulating experiment, an immersion experiment and a damp-heat experiment. The method is based on a statistic experiment and the regression analysis method, and is more practical than a simple theoretical analysis result; the advanced experimental equipment and the scientific experimental method are adopted, so that the objectivity and accuracy of the experiment data and model are guaranteed.

Description

technical field [0001] The invention belongs to the technical field of electric power and communication, and relates to a method for establishing an optical fiber fault aging model. Background technique [0002] As the application of optical fiber in the power system communication network becomes more and more popular, the reliability and fault monitoring of optical fiber become more and more important. At the same time, due to the vast territory of our country and the relatively large environmental differences between regions, the application environment of optical fibers is also very complicated. The loss of optical fibers is often the main factor causing the failure of power optical fiber cables. [0003] In order to enable the maintainers to quickly deal with the failure of the power optical cable during the maintenance of the optical cable, and provide a quick response to the power market service, while ensuring reliable and economical energy to the user, it is necessar...

Problems solved by technology

[0004] At present, most research institutions and scientific research institutes tend to explore and research theoretically (such as fuzzy theory, artificial nerve, etc.) on optical fiber fault monitoring, and carry out application and data analysis and state diagnosis, which is difficult for users to grasp. , did not fully consider the operability of front-line operation and maintenance personnel

During the construction and long-term use of optical cables, under the influence of stress or environmental factors, the attenuation increases. For the maintenance of optical cables, there is currently no practical standard method to guide the maintenance of optical fibers. It is a convenient and fast fault judgment method for optical fiber in actual work

The monitoring research of power optical fiber can fully learn from the research results of public communication, but it cannot simply copy the results. It must also consider the network characteristics, operation management and other particularities of power optical fiber communication, combined with the actual power system, and conduct in-depth research on optical fiber monitoring. The key technologies for monitoring the network construction process provide support
