The invention belongs to the field of bridge engineering, and particularly relates to a wind vibration monitor and an inhaul cable bridge wind-induced vibration directional accurate monitoring, sensing and early warning system.The wind vibration monitor comprises two sets of inhaul cable installation pieces, two sets of installation supports, two sets of first magnets and piezoelectric patches, and the two sets of inhaul cable installation pieces are arranged in the axial direction of an inhaul cable at intervals; the two sets of mounting supports are arranged on the two sets of inhaul cable mounting pieces correspondingly and oppositely arranged in the axial direction of the inhaul cable, the two sets of first magnets are connected to the two sets of mounting supports correspondingly and oppositely arranged in the radial direction of the inhaul cable, and the piezoelectric patches are located between the two sets of first magnets and between the two sets of mounting supports. Springs are arranged between the two sides, in the axial direction of the inhaul cable, of the piezoelectric patch and the corresponding installation supports, and the two sides, in the radial direction of the inhaul cable, of the piezoelectric patch are each provided with a set of second magnets. Based on signal identification, piezoelectric effect and cloud computing technology, the monitoring precision of the bridge under the influence of wind load is improved, and the cable bridge cluster monitoring and linkage feedback function of the cloud computing monitoring platform is realized.
