Investigation And Analysis Of Hidden Troubles Of High Pressure Pipeline Occupancy In Town Gas Based On Remote Sensing Images

With the continuous acceleration of the urbanization process and the continuous popularization of natural gas development,some areas have begun to violate the regulations to occupy natural gas pipelines,resulting in hidden dangers of pipeline occupation,affecting the normal operation of the pipeline and endangering the safety of surrounding residents.At present,the inspection of hidden dangers of gas pipeline pressure is mainly based on manual inspection,but there are still some problems that need to be solved.This article establishes a remote gas image based investigation and analysis model of hidden hazards of high-pressure gas pipelines in cities and towns.By combining remote sensing images,pipeline information,area occupied by buildings,and distances from buildings,etc.,the hidden hazards of gas pipeline occupied pressures are investigated for comprehensive Analyze the risk of hidden danger of gas pipeline pressure,provide decision-making reference,solve the problem of manual inspection,and complete the conversion from traditional manual inspection to human-computer interaction.Based on the investigation of relevant situations at home and abroad,the characteristics of urban gas pipeline pressure hidden dangers,common hidden trouble investigation methods and gas pipeline risk assessment methods are analyzed and analyzed;by comparing the performance of current typical remote sensing satellites,the information of gas hidden danger images is extracted and Semantic segmentation to identify the targets that may cause hidden dangers in the remote sensing images and gas pipelines;the specific process and operation method of each step of the gas pipeline pressure hidden danger investigation and analysis model based on remote sensing images;the model is applied to actual cases Practice in the process;put forward suggestions on the treatment methods of hidden dangers,and provide reference for the subsequent treatment of hidden dangers.
