The invention discloses a wind power tower modal analysis method and system based on FMCW four-dimensional laser radar dual-stage scanning. According to the method, the unique capability of an FMCW laser radar for directly measuring the radial speed of a target based on the Doppler frequency shift principle is utilized, and three-dimensional space coordinates and speed information are synchronously obtained to form a four-dimensional point cloud. The method adopts a double-stage scanning strategy: in the first stage, the overall geometric morphology of the tower drum is quickly obtained through spiral scanning with an oscillation compensation item; and in the second stage, self-adaptive vertical line reciprocating scanning is performed based on the geometric model to obtain high-density time sequence speed data. A time sequence speed matrix is constructed through a weighted median algorithm, and modal parameters are calculated and extracted in combination with frequency domain analysis and fusion damping ratio. The contradiction between space coverage and time resolution in the prior art is solved, and compared with a traditional method, the scanning efficiency is improved by more than 80%, and the damping ratio recognition precision is improved by more than 50%.

This invention belongs to the field of intelligent transportation technology, specifically relating to a global-local green wave traffic method for smart buses at multiple intersections in a 5G-CV2X vehicle-road-cloud collaborative environment. This method uses 5G-V2X equipment to obtain real-time driving status of buses, real-time road conditions, and real-time phase information of traffic lights at multiple intersections. First, based on the green light ratio objective function, a global optimization algorithm is initiated to globally optimize the phase duration of traffic lights at multiple intersections and the bus speed. However, the global optimization algorithm does not consider the queuing situation of other vehicles at the intersection. The local optimization algorithm mainly relies on the real-time queuing situation of buses at the intersection, and re-plans the bus speed at subsequent intersections based on the global optimization. This invention solves the problems of green wave traffic for buses at multiple intersections and the time delays caused by vehicle queuing during priority passage, thereby greatly improving the traffic efficiency and punctuality of buses at multiple intersections.
