and if the residual life of the fan is not greater than the third preset life value, sending fan stop information.

When the accumulated running time of the fan running time counter is more than or equal to one day, the day counter is automatically increased by 1.
When the count value of the fan operation time counter is greater than or equal to 172800, the fan operation time counter is automatically increased by 1, wherein 172800 is obtained by converting the time of 1 day into 500ms, namely 24 hours, 60 minutes, 60 seconds and 2.
The fan day operation counter is compared with a first preset service life value (for example, 60 months, namely 59 months and 30 days) and if the first preset service life value is larger than or equal to the preset service life value, fan service life early warning information can be sent out one month in advance, and a user can be prompted to prepare a fan needing to be replaced in advance.
