Body comprises the steps of：
S31, first singlechip module judge the range residing for the environment temperature T got, export corresponding wind-speed gear information
To relay module；
When environment temperature T is less than preset lowest threshold, first singlechip module will not be to relay module output wind speed shelves
Position information, continues S32；
When environment temperature T is between preset lowest threshold and highest threshold value, first singlechip module is according to the environment temperature
The temperature range residing for T is spent, corresponding wind-speed gear information is exported to relay module, continues S33；
When environment temperature T is higher than preset highest threshold value, first singlechip module exports most high-grade wind to relay module
Fast gear information, and control alarm module and give a warning, continue S33；
S32, relay module do not generate corresponding Trig control signal, and DC fan will not start；
S33, relay module generate corresponding Trig control signal according to the wind-speed gear information got.
10. the control method of the isolated form intelligent temperature control fan assembly as described in right 9, which is characterized in that in the S3, also
Including：Ambient temperature information and wind-speed gear information are sent to display panel module and shown by S34, first singlechip module,
And it is sent to voice module to be reported.
