POWER TRANSMISSION LINE WILDFIRE FINE POSITIONING METHOD BASED ON BRIGHTNESS TEMPERATURE VALUE ANALYSIS

WIPO Patent Application WO/2015/169162

A1

A power transmission line wildfire fine positioning method based on brightness temperature value analysis, comprising the following steps: (1) infrared data is obtained; (2) wildfire fire points are identified; (3) sub-grids are divided; (4) a sub-grid in which a fire point is located is determined: (4.1) if fire points are present in grids surrounding a grid, it is indicated that the fire point is present in the grid; (4.2) if there is a grid in which a fire point is not present, it is indicated that the fire point is near to a sub-grid of a grid in which a fire point is present; (4.3) if fire points are not present in the surrounding grids, and a brightness temperature value is the same, it is indicated that the fire point is located in the centre of the grid. The present method: 1) has a clear principle, convenient operation and high practical value; 2) effectively improves fire point positioning accuracy, and makes up for the deficiencies of low satellite monitoring data resolution; 3) effectively improves wildfire warning accuracy for a power grid, and ensures safe operation of the power grid.
