The present application provides an intelligent control system for touch switch based on infrared sensor detection, which comprises: a position determination module, for setting infrared sensors in the first position, the second position, the third position, and the fourth position respectively, which are used to detect whether a person passes the current position; a time statistics module, for calculating the total time consumed by the target person passing through the first position, the second position, and the third position based on the detection result of those infrared sensors; a time determination module, for calculating the target time consumed by the target person passing from the third position to the fourth position; an intelligent control module, for selecting whether to turn on the light guide line from the fourth position to the position of the touch switch.
