Snow cover detection method, snow melting control method, and snow melting device

摘要

A snow accumulation detection method, a snow melting control method, and a snow melting device capable of reliably detecting snow accumulated on the roof of a horticultural facility with a simple configuration and further melting the snow reliably. A snow melting device (10) for detecting snow accumulated on a roof (2) of a horticultural facility (1) having a roof (2) that transmits light and performing a snow melting process based on the detection result. The difference between the indoor light amount detected by the indoor light detector 13 and the outdoor light amount detected by the outdoor light detector 14 and the outdoor light detector 14 provided outside the garden facility 1 A control unit that calculates the light transmittance into the horticultural facility 1 through the roof 2 based on the amount of light, detects that there is snow on the roof 2 when the light transmittance is a predetermined value or less, and executes a snow melting process C.
