The invention discloses a humidity control method for a dehumidifying and anti-seepage device, and belongs to the technical field of dehumidifying and anti-seepage equipment control. In view of the fact that the control precision of the existing dehumidifying and anti-seepage equipment is not high and the flexibility of control is insufficient, the method obtains comprehensive and accurate data through using the grid optimization arrangement method and reasonably arranging collection points, takes the desired humidity, i.e., Hum wall 0, Hum air 0, as a target center, and performs optimized andintegrated calculation of collected data. Through the fuzzy control, the output voltage of main control equipment under the stable working state is obtained, and multiple output voltage switching selections of the desired humidity can be realized, which can improve the control accuracy and the control flexibility. Considering the impedance effect of the actual wall, the closed-loop voltage regulation is performed, so that the stable state that the wall voltage and the output voltage of the main control equipment under the stable working state are the same is achieved in a short time.
