Method and system for detecting cross-sectional temperature field of furnace with single infrared probe

A method for detecting a cross-sectional temperature field of a furnace with a single infrared probe, comprising:

• acquiring environmental information of a preset simulated detection space and a periphery of the furnace through a combination of sensors disposed around the furnace, wherein the environmental information comprises temperature information, humidity information, and wind force information;
• at a plurality of time points in a simulated detection cycle, collecting a first detected temperature at a first preset point by using a single infrared probe disposed at a first preset position, and determining a first distance between the first preset position and the first preset point;
• collecting a second detected temperature at the first preset point by using a temperature sensor disposed at the first preset point;
• determining an error relationship function based on the first distance, the first detected temperature, the second detected temperature, and the environmental information;
• at the plurality of time points in the detection cycle, collecting cross-sectional temperature data of the furnace at a plurality of second preset points in a cross-section of the furnace by using second single infrared probes disposed at a plurality of second preset positions in the furnace, and determining coordinate information of the plurality of second preset points in a furnace coordinate system, wherein the furnace coordinate system is a coordinate system established based on a centroid of the cross-section of the furnace;
• determining a detection score of the cross-sectional temperature field of the furnace based on the cross-sectional temperature data of the furnace and the coordinate information;
• and
