Research On The Kev Technologies Of Large Scale Multi-parameter Optical Fiber Micrometeorological On-line Monitoring System

The monitoring of micrometeorological index is closely related to the production and life of human beings.Micrometeorological monitor is widely used in all fields of production and life including intelligent power transmission system.The safety and operating efficiency of power transmission system are affected by the measurement of various environmental micrometeorological indexes.At present,most of the sensors used in the micrometeorological online monitoring system are based on the power transmission mode,which are short in transmission distance,low in transmission rate and subject to electromagnetic interference.The system itself is mostly single architecture mode,with low information capacity and limited monitoring management ability,which cannot meet the requirements of large-scale monitoring and industrial-level data volume,and the application field has great limitations.With the development of sensor,communication,Internet of things and other technologies,the micro-meteorological monitoring of a large scale and various indicators of power system has become an urgent need.Therefore,the purpose of this paper is to research and design a large-scale multi-parameter optical fiber micrometeorological on-line monitoring system,which can make up for the deficiency of micrometeorological monitoring in the existing intelligent power transmission system and help to build an intelligent society.The main research work and results are as follows:1.Based on the theoretical analysis and the requirements of practical application scenarios,the simulation models of the structures of various fiber-optic micrometeorological monitoring sensors are established.On the basis of simulation,the structure of the fiber optic micrometeorological index monitoring sensor and its integration scheme are developed and verified.2.Based on the hardware of fiber Bragg grating demodulator,a high rate demodulator system is developed which can simultaneously load multiple demodulators and demodulate multiple channels and parameters.3.Based on JAVAEE,TCP/IP,micro services such as technology,has realized the online monitoring software system,covering the sensor configuration management,monitoring information of computation and rendering,alarm management,statistics management,in the form of a variety of visual data presentation,data export,user management,role management,and other functions.Besides,thirough the example from the Angle of hard and soft demonstrates the development of system scalability which developed in this thesis.
