The embodiment of the invention provides a tobacco process quality control method, system and device and a storage medium, and relates to the technical field of tobacco industry. The tobacco process quality control method is based on a cloud platform and comprises the following steps: acquiring tobacco process data in a production process; judging whether the tobacco process data is abnormal or not, and if the tobacco process data is abnormal, obtaining the tobacco process data again; if the tobacco process data is not abnormal, judging whether the tobacco process data meets the production process technical standard or not, and obtaining a judgment result; and according to the judgment result, calling a corresponding solution from a tobacco industry database. According to the method, through process quality defect control and process parameter self-adaptive deviation rectification, self-adaptive optimization on a process program is realized, the productivity and the production qualityare improved, and meanwhile, the labor cost and the time cost are reduced.
