Remote sensing monitoring method and system for capacity change of iron and steel enterprise

Abstract

The invention relates to a remote sensing monitoring method and system for a capacity change of an iron and steel enterprise. According to the method provided by the invention, with thermal infrared remote sensing data, inversion of a thermal environment field of an iron and steel enterprise is carried out; thermal abnormal time change characteristics and spatial distribution change characteristics of the iron and steel enterprise are analyzed; and on the basis of the thermal abnormal time change characteristics and spatial distribution change characteristics of the iron and steel enterprise, a capacity change remote sensing monitoring algorithm for an iron and steel enterprise is constructed to monitor the capacity change situation of the iron and steel enterprise. On the basis of the specific thermal environment characteristics of the iron and steel enterprise and a spectral response rule of the iron and steel enterprise at a thermal infrared waveband, precise remote sensing monitoring of the capacity change of the iron and steel enterprise is realized.

Description

technical field [0001] The invention relates to the technical field of social and economic remote sensing, in particular to a remote sensing monitoring method and system for production capacity changes of iron and steel enterprises based on the spatio-temporal distribution characteristics of the thermal environment. Background technique [0002] The status of steel production capacity reduction mainly depends on the data reported by local governments and enterprises, and the existence of false reports, concealed reports, and omissions cannot be ruled out; at the same time, the results of capacity reduction that have been achieved still need to be stabilized to prevent rebound. Therefore, it is necessary to give full play to the advantages of space observation technology, strengthen the dynamic monitoring and monitoring of overcapacity reduction enterprises, and provide information support for the country to fully control the implementation process of overcapacity reduction. ...

AI Technical Summary

Problems solved by technology

[0005] In view of the background of overcapacity in our country, the on-site investigation of the production capacity of iron and steel enterprises faces various difficulties, and the problems that the authenticity of the data reported by the enterprises cannot be distinguished, and provides a remote sensing monitoring method for the production capacity change of iron and steel enterprises based on the spatio-temporal distribution characteristics of the thermal environment. The spectral response law of iron and steel enterprises in the thermal infrared band and the spatio-temporal distribution characteristics of the thermal environment have realized the precise remote sensing monitoring of the production capacity changes of iron and steel enterprises
