The invention discloses a rolling mill vibration wireless monitoring method based on segmented windowing frequency domain integration, and belongs to the technical field of rolling mill vibration monitoring. The method comprises the following steps of: 1, installing vibration monitoring devices at multiple positions of the rolling mill, and dynamically generating a connection routing table according to network density and battery electric quantity to realize intelligent wireless networking; 2, the main control chip communicates with the vibration sensor and collects a vibration acceleration signal of the rolling mill; thirdly, the collected rolling mill vibration acceleration signals are corrected, and trend terms are removed; 4, segmented windowing is carried out on the corrected vibration acceleration signal, frequency domain integration and filtering are carried out, and a speed signal and a displacement signal after segmented integration are obtained; 5, real speed and displacement signals are synthesized
