The invention discloses an infrared humidification device and a control method. The device comprises a plurality of infrared light sources, a lampshade, a water storage structure, a water inlet structure, a water level switch and a controller. The water storage structure comprises a water storage tank, an overflow valve and a drainage pipe. The water inlet structure comprises a water inlet pipe, a water inlet electromagnetic valve and a water injection pipe. On-off of a power supply circuit of the multiple infrared light sources is controlled by the controller, a current transformer is arranged in the power supply circuit of the infrared light sources and used for collecting current values, and the current values are transmitted to the controller. According to the infrared humidification device and the control method, radiant energy of the infrared light sources is adopted for heating and evaporating water, the requirement for water quality is not high, and the application range is wide; the water storage tank is automatically cleaned, the daily maintenance workload is reduced, and the maintenance cost is reduced; and the current values are collected by the current transformer and transmitted to the controller, the controller controls on-off of the power supply circuit of the infrared light sources according to the current values, and the situation that the infrared light sources are burnt out due to abnormal current is avoided, so that the safety and stability of the whole device are improved.
