The Design And Implementation Of The Distributed Optical Fiber Sensors System Software

Power industry is the basic energy industry in the national,It is the key industry in the world.Due to China's economic development,the demand for electricity has continued to expand.Ensuring the safety of power system is the most important.because transmission is part of the power system,this paper mainly discusses a temperature monitoring system used to prevent fires.because the underground tunnel laying power cables are high voltage cables,these cables are in a closed environment for a long time,carrying high voltage and high current,Lead to higher heat inside the cable.on the one hand,the high temperature increases the loss of power system energy,on the other hand,the high temperature caused by the high current load will affect the normal operation of the cable equipment,and There will be danger.Because of the high temperature danger of high voltage cables,we need effective temperature monitoring for high voltage cables,the traditional temperature measuring device cannot meet the temperature measurement of the distance,multi-point and real-time,however,distributed optical fiber machine has been effective in solving the above problems.The distributed optical fiber temperature measuring machine is a kind of monitoring machine which uses temperature measurement technology to measure and locate the fiber temperature in real time.when the temperature anomaly is detected,the alarm will be reported in time,and timely notify users to take safety measures by voice signal and network signal,this ensures the safe operation of the high voltage cable in the tunnel.This paper mainly introduces the design and implementation of the distributed optical fiber temperature measuring host software.it is developed using c ++language and waterfall model,from the perspective of waterfall model,I will focus on the four chapters of this article:functional requirements,architecture design,detail design and software implementation.In the first chapter,the development background and current situation are discussed in general.The second chapter introduces the distributed optical fiber temperature measurement technology,and then introduces how to obtain the functional requirements through the demand analysis.The third chapter discusses the design objectives and principles of software design,and summarizes the software architecture from three perspectives of physical architecture,logical architecture and operational architecture.In the fourth chapter,the software architecture design is completed and the software is designed in detail.Includes three parts:class design,interface design and database design.In chapter 5,we introduce the realization of the software of the fiber temperature measuring host,discuss the development of the core module,and introduce the derivation process of temperature calculation formula.
