Therefore, the controller can receive the first current concentration of organic waste gas molecules in the current gas at the gas outlet, the second current concentration of organic impurities in the current gas, and/or the current temperature of the cavity detected by the sensor.

In addition, when the controller obtains the target characteristic parameters in the indoor air purification equipment, it can be obtained individually, or in pairs, or at the same time. Obtain the second current concentration of organic impurities in the current gas, and then obtain the current temperature of the cavity, or first obtain the second current concentration of organic impurities in the current gas and the current temperature of the cavity, and then obtain the current temperature of the organic waste gas molecules in the gas. For the first current concentration, the first current concentration of organic waste gas molecules in the current gas at the gas outlet, the second current concentration of organic impurities in the current gas, and the current temperature of the cavity can also be obtained simultaneously.

Moreover, the first preset reference concentration may be a first reference concentration threshold, or may be a first reference concentration range. There is no limitation here.

Specifically, when the controller obtains the first current concentration of organic waste gas molecules in the current gas at the gas outlet via the sensor, the controller may further match the first current concentration with the first preset reference concentration, for example, match the first current concentration with The magnitude of the first reference concentration threshold is compared, or the magnitude of the first current concentration is compared with the maximum value and the minimum value of the first reference concentration range, so as to obtain the first target matching result.

Step S1022, when the first target matching result indicates that the first current concentration is higher than the first preset reference concentration, determine a target processing strategy including increasing the power of the ultraviolet light source.

Specifically, when the controller determines that the first target matching result indicates that the first current concentration of organic waste gas molecules in the current gas at the air outlet is higher than the first preset reference concentration, it may be considered that the organic waste gas molecules in the air entering the indoor air purification device If it has not been treated up to the standard and will produce secondary pollution, a target treatment strategy including increasing the power of the ultraviolet light source can be determined, so that the indoor air can be treated by indoor air purification equipment to produce clean air that meets air emission standards and will not produce secondary pollution. gas; wherein the first current concentration of organic waste gas molecules in the current gas at the gas outlet is higher than the first preset reference concentration may include that the first current concentration is greater than the first reference concentration threshold or the first current concentration is greater than the first reference concentration range. maximum value.
