Real Time Monitoring of Terminal Equipment Status in Rural Distributed Comprehensive Energy System Based on Fiber Optic Sensing
The environmental conditions in rural areas are complex and variable,and the climate has an impact,making termi-nal equipment prone to temperature anomalies.During the process of sensor acquisition and signal transmission,temperature signals are affected by factors such as electromagnetic interference and transmission signal attenuation,resulting in noise and interference with their true frequency characteristics.It is difficult to accurately identify abnormal frequency components and monitor temperature anomalies accurately.To this end,a real-time monitoring method for the terminal equipment status of ru-ral distributed comprehensive energy systems based on fiber optic sensing is proposed.By deploying fiber optic sensors in termi-nal devices and utilizing fiber optic sensing technology,separation and processing can effectively reduce the impact of these in-terferences on the real temperature signal,obtain the key temperature parameters of the terminal device,use fiber optic grating dynamic signal processing technology to perform Fourier series decomposition on the above parameters,avoid the impact of noise interference on temperature anomaly monitoring,analyze the periodic and transient dynamic information of the terminal device,and observe subtle changes in real-time to obtain the current operating temperature of the device,achieving real-time monitoring of the terminal device status of the rural distributed comprehensive energy source system.Using FlexSim software to construct four simulated experimental environments:sunny,rainy,thunderstorm,and strong wind,collect actual tempera-ture data of rural distributed comprehensive energy system terminal equipment,and monitor the temperature of wind turbines.Under the four weather conditions,the design method is closer to the actual value,proving that the design method can effec-tively resist the influence of complex and variable weather,and achieve accurate monitoring of equipment temperature.
