Photovoltaic module surface ash deposition state monitoring device based on spectral radiation force acquisition

The invention discloses a photovoltaic module surface ash deposition state monitoring device based on spectral radiation force acquisition. The detection device comprises a detector and a controller, in the detector, a transmitting system horizontal supporting rod and a dust accumulation side receiver supporting rod are fixed to the upper end and the lower end of a main installation rod respectively, and a laser transmitter is installed at the end of the transmitting system horizontal supporting rod through a laser transmitting system installation frame. The dust accumulation side power receiver is fixed at the end part of the dust accumulation side receiver supporting rod, a laser emitting part of the laser emitter is over against the dust accumulation side power receiver below, and a photovoltaic glass plate to be detected is positioned between the laser emitter and the dust accumulation side power receiver; and the dust accumulation side power receiver is connected with a signal collecting and transmitting
