Abstract

The invention provides a method for realizing system variation early warning based on tightening curve artificial intelligence analysis. According to the method for realizing system deterioration early warning based on artificial intelligence analysis of the tightening curve, the characteristic attributes of the stick-slip curve during tightening are utilized, the curve change mode in the tightening process is identified and analyzed, and the stick-slip problem is detected and early warned in time, so that the situation that a product is not tightened firmly or is tightened excessively can be avoided, and the product quality is improved. The product quality is ensured to meet the requirement; the stick-slip curve is collected and analyzed in real time, so that the stick-slip problem can be early warned in time, production line shutdown or production delay caused by product problems can be avoided, and the production efficiency is improved; by reducing the product rejection rate caused by the stick-slip problem, the production cost can be reduced, and the economic benefits of enterprises can be improved.
