The invention discloses a lifting early warning control system and method for an ultra-long and ultra-heavy component, the lifting early warning control system comprises strain data acquisition units, a strain data processing unit and a lifting early warning unit, the strain data acquisition units are arranged at lifting point positions of all lifting mechanisms and are used for acquiring real-time stress data in the lifting process; the strain data processing unit is used for acquiring and preprocessing real-time stress data, and extracting strain characteristic parameters reflecting the stress state of the structural member based on the preprocessed real-time stress data; the hoisting early warning unit is configured in the control system after training is completed, and hoisting early warning information is output based on the strain characteristic parameters and output to the human-computer interaction interface. Two kinds of heterogeneous data of strain and video are fused, richer state information can be obtained, and more accurate state estimation is realized; and safety and reliability of lifting operation are guaranteed to the greatest extent.
