The present invention provides a green hotel assembled linen channel electric control system and method, the system includes: a card swiping system; a main control system and a prompt system electrically connected to the card swiping system; when the card swiping system is in use, it sends a first state signal of being in use to the prompt system located at the exit of the linen channel at the bottom of the hotel; when the card swiping system is not in use, it sends a second state signal of not being used to the prompt system located at the exit of the linen channel on each floor of the hotel; the main control system locks the entrance of the linen channel in the unused state according to the second state signal. The scheme of the present invention enables the hotel linen channel to have the function of intelligent control, and at the same time prompts the personnel located at the exit at the bottom of the linen channel to pay attention and avoid accidents.
