Design And Implementation Of Communication Optical Cable Monitoring And Forecasting System

The total length of optical cable lines in China ranks first in the world,with a total optical fiber length of more than 240 million kilometers.With the improvement of optical fiber coverage and the gradual promotion of 5G base station construction,the laying scale of optical fiber and optical cable is becoming larger and larger,and the daily maintenance of optical cable is becoming more and more important.At present,the maintenance of optical cable is faced with problems such as low efficiency,insufficient informatization and intelligent level.The active operation and maintenance system designed and implemented by this paper for optical cable aims to solve these problems.The system takes optical cable status monitoring and attenuation prediction as the core function,which can greatly improve the maintenance efficiency of optical cable.This paper mainly completes the following work:Firstly,the current situation of optical cable condition monitoring and Attenuation Prediction at home and abroad is discussed;According to the common faults and types of optical cable,the optical cable monitoring scheme based on the monitoring data discrimination of optical time domain reflectometer is determined;According to the characteristics of optical cable attenuation data,the attenuation prediction scheme based on combined prediction m odel is determined,and the relevant principles are expounded respectively.Secondly,the data encapsulation of the system input is designed;Through the mutual verification between the monitoring data of optical time domain reflectometer and actual cases,the specific types of optical cable faults are automatically identified;Through the comparative analysis of different prediction models after training,the prediction of optical cable attenuation information is realized.Then,the function design of user authority management module,operation log module and historical alarm module is realized based on MySQL database.The system information output is realized based on HTML language.The function design of alarm module is realized based on C++ mail interface;The software function modules are encapsulated based on MFC framework,and the system including optical cable status monitoring module,optical cable attenuation prediction module,user authority management module,operation log module,historical alarm module and alarm module is realized.Finally,it briefly introduces each interface of the system,and completes the verification of the system function through the interpretation of the system output report.The results show that the system meets the requirements,achieves the design goal,and has high practical value.
