Research And Implementation Of Distributed Optical Fiber Monitoring And Management Software Platform

With the development of economy and society,the dependence on electric power is becoming more and more obvious.With the large-scale increase of electric power optical fiber communication lines,the demand for monitoring and management of optical cable lines is growing.In optical cable monitoring technology,optical fiber sensor has many advantages,such as small quality,high sensitivity,long transmission distance and so on.In recent years,it has been widely used in optical cable line monitoring.Fiber Bragg grating(FBG)technology has become one of the most widely used optical cable monitoring technologies because of its passive,real-time and high-precision characteristics.However,FBG is a point sensor,which can not measure the whole transmission line without blind area in a large range.The distributed optical fiber monitoring technology based on Brillouin optical time domain reflectance(BOTDR)can make up for the above shortcomings of FBG sensor,so that there is no blind area coverage along the whole optical fiber,but the cost of BOTDR is high;at present,the main monitoring environmental parameters are temperature and stress,which are relatively single,and can not meet the demand of real-time monitoring.In view of the above problems,this paper carries out the research based on distributed optical fiber monitoring and management system.The main research contents are as follows1.Combining FBG sensing technology with distributed optical fiber monitoring technology,a distributed optical fiber monitoring method based on point line combination is designed.On this basis,a distributed optical fiber monitoring and management software platform is designed and developed.2.Design a unified and efficient optical fiber resource display method based on GIS map.According to this method,the GIS map module is developed on the distributed optical fiber monitoring management software platform.3.Design a method to accurately locate the fault points detected by sensors in GIS map.This method can show the specific location of the current optical cable line fault point in GIS map in real time.And the display function of GIS map fault point is developed on the distributed optical fiber monitoring management software platform.
