The invention belongs to the field of hoisting operation safety control, and discloses a gantry crane brake swing early warning system and method for subway shield tunnel segment hoisting. The early warning system comprises a hoisting data acquisition module, a data analysis and prediction module and a segment swing early warning module, wherein the hoisting data acquisition module is used for acquiring spatial information of subway segments in the underground hoisting process in real time; the data analysis and prediction module reasonably predicts the future hoisting track of the subway segments through the acquired data; and the segment swing early warning module calculates and judges the possible swing size of the subway segments according to the hoisting prediction track and outputs acorresponding early warning signal. Hoisting track prediction is performed based on the composite model of data driving and motion analysis so that early warning control can be performed on unsafe swing of the subway segments in the hoisting deceleration brake stage through the reasonable and accurate prediction track, safety control of the underground hoisting process of the subway segments canbe optimized and the subway segment hoisting accident can be actively avoided.
