Monitoring method and equipment for coating machine drying oven heat recovery device and storage medium

The invention relates to a monitoring method and equipment for a coating machine oven heat recovery device and a storage medium. The monitoring method comprises the steps that gas working condition data of the oven heat recovery device are acquired; establishing a calculation model of the heat exchange efficiency of the gas-gas heat exchanger, establishing a calculation model of airtight parameters for reflecting the air tightness of the drying oven, and establishing a calculation model of heat preservation parameters for reflecting the heat preservation property of the drying oven; a heat exchange efficiency value is calculated according to the gas working condition data and the calculation model of the heat exchange efficiency, an airtight parameter value is calculated according to the gas working condition data and the calculation model of the airtight parameters, and a heat preservation parameter value is calculated according to the gas working condition data and the calculation model of the heat preserva
