[0002] A thermal power plant, also known as a thermal power plant, is a factory that uses coal, oil, and natural gas as fuel to produce electricity. The fuel is burned in a boiler to heat water to generate steam, converting the chemical energy of the fuel into thermal energy. The steam pressure drives the turbine to rotate, converting the thermal energy into mechanical energy. The turbine then drives the generator to rotate, converting the mechanical energy into electrical energy.

[0003] In the process of power generation, thermal power plants add pulverized coal to the boiler, and the number of boxes and frames for adding pulverized coal needs to be identified through OCR, thus eliminating the need for manual supervision.

[0004] However, when the added coal powder is identified through OCR, the coal powder can easily drift onto the lens of the equipment, causing the OCR recognition lens to be blocked, affecting the OCR's recognition of the coal powder. In addition, the temperature inside the thermal power plant is relatively high, which can easily cause the OCR recognition equipment to overheat and affect normal use. Utility Model Content
