[0021] S6. In step S5, the pipe temperature sensor is used to monitor the air temperature at the outlet of the heater, and the temperature data is sent to the central processing unit through the signal processing module, and the central processing unit adjusts the power of the heater in real time according to the temperature;

[0022] S7. When the central processing unit detects that the weight of the roof has become lower according to the pressure sensor, it means that the snow has been removed, and the circulation motor, heater, and heat exchange fan are turned off.

[0023] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:
