The embodiment of the invention provides a unit blade identification method and device, equipment and a storage medium, and belongs to the technical field of fan blade state monitoring. The unit blade identification method comprises the following steps: measuring a unit blade by using a laser vibration measurement technology to obtain blade vibration data, and then obtaining blade operation condition data and blade fatigue crack data by respectively using a condition identification model and a fatigue crack identification model based on a convolutional neural network based on the blade vibration data. According to the embodiment of the invention, the laser vibration measurement technology is utilized to measure the vibration of the blade, the cost of blade vibration measurement and the difficulty of measurement operation are reduced, the working condition recognition model and the fatigue crack recognition model are established based on the convolutional neural network, and the accuracy of blade recognition i
