The invention discloses a method for hoisting in a warehouse based on a similarity comparison process. In the use of a lifting rope, a measuring rope fixed together with the lifting rope can completely simulate the deformation situation of the lifting rope; stress on the measuring rope can be measured by the measuring rope itself, and the deformation state of the measuring rope is within a limit range; and stress on the lifting rope can be indirectly acquired in virtue of a fixed proportional relation between the stress on the measuring rope and the stress on the lifting rope. The method of the invention employs the similarity comparison process; an auxiliary rope is additionally arranged on the original lifting rope, and the stress on the lifting rope is calculated by measuring the stresson the auxiliary measuring rope; through comparison between counterweight with known weight and historical data during hoisting, self-inspection of the lifting rope is realized; and thus, the functions of real-time monitoring and self-inspection of the lifting rope in the process of hoisting are realized. Moreover, fixed values are set in each stage, the actual stress of the monitored lifting rope and the set values are compared, and when the actual stress is greater than the set values, early warning information is sent; and thus, the reliability of hoisting is improved.
