Wind power plant transmission tower monitoring method and system

The invention relates to a method and a system for monitoring transmission towers of a wind power plant. The method comprises the following steps: acquiring vibration parameters and attitude data of each transmission tower; each power transmission tower is provided with a communication node, the power transmission towers adjacent to the gateway are provided with aggregation nodes, the communication nodes of the adjacent power transmission towers communicate with each other, and vibration parameters and attitude data of each power transmission tower are transmitted to the aggregation nodes; the sink node sends the vibration parameters and the attitude data of each transmission tower to a gateway, and the gateway sends the vibration parameters and the attitude data of each transmission tower to a server. The invention provides a method and a system for monitoring a power transmission tower of a wind power plant. The technical problem that vibration, inclination and other states of the power transmission tower c
