Novel system for vane condition monitoring and early fault alert of wind turbine

The invention relates to the technical field of safe early alert of cooling towers, in particular to a novel system for vane condition monitoring and early fault alert of a wind turbine. The system includes vane marks, an image collection subsystem, a data transmission subsystem, a condition motoring subsystem and a fault diagnosing subsystem; the vane marks are positioned on the vane tips; the image collection subsystem is connected with the data transmission subsystem through a GPRS wireless transmission module or a light ray emitter; the data transmission subsystem is connected with the condition monitoring subsystem and the fault diagnosing subsystem through an Internet or an optical fiber; the condition monitoring subsystem is used for displaying the running conditions of vanes in real time; the fault diagnosing subsystem includes an image processing program, an alerter and a fault database. By monitoring the position and condition changes of the vane marks, the running conditionsof the vanes of the wind
