The present invention belongs to the technical field of abnormal detection of wind turbines, and specifically provides a tower abnormal vibration detection method, device, equipment and medium. The method comprises the following steps: obtaining the unit drive side vibration data, non-drive side vibration data, pitch angle data and power data of each unit collected by SCADA and aligning the acquired data in time sequence; processing the acquired data to generate a data list; detecting the data in the data list in time sequence to determine whether the unit tower has abnormal vibration; determining whether abnormal vibration of the tower caused by pitch abnormality occurs according to the pitch angle and vibration amplitude; determining whether the vibration deviates from the zero axis according to the sum of bins within the tower unit time; and outputting corresponding abnormal warning information based on the determination result. Effectively monitor the tower tilt problem and reduce related operation and maintenance costs.

The invention discloses a point-type process and device for rapidly measuring the carbon value of sponge titanium by reducing titanium tetrachloride in the technical field of non-ferrous metal metallurgy, and the point-type process comprises the following steps: step 1, charging: respectively introducing gaseous titanium tetrachloride and liquid magnesium into a feeding pipe and a magnesium adding pipe of a reduction furnace; step 2, reaction: adjusting the temperature and pressure in the reduction furnace, and introducing argon into the reduction furnace at the same time, so that the titanium tetrachloride reacts with the liquid magnesium; step 3, sampling: adjusting the feeding speed of the liquid magnesium and the gaseous titanium tetrachloride, enabling the liquid magnesium and the gaseous titanium tetrachloride to react above a sampling platform, continuously introducing argon below the sampling platform of the reduction furnace to blow away the attached sponge titanium, and after the sponge titanium on the sampling platform is dispersed, taking out the sponge titanium generated by the reaction on the sampling platform; and 4, testing: testing the taken-out sponge titanium, and detecting the carbon content of the sponge titanium. According to the scheme, the problem that in the prior art, sponge titanium production is easily interfered during sampling can be solved.
