Production line control method and production line

The invention relates to the technical field of production lines, particularly provides a control method of a production line and the production line, and aims to solve the problem that fault points of an existing production line are difficult to check. In order to achieve the purpose, the control method of the production line comprises the steps that production information of each workpiece is obtained, and whether procedure stations need to be checked or not is determined according to the production information; if the number of unqualified workpieces manufactured by a single process station in single process equipment is greater than or equal to a second preset number, or the qualification rate is smaller than a second preset qualification rate, the process station of the process equipment may have defects, so that the workpieces manufactured by the process station are easily unqualified, and the yield of the workpieces manufactured by the process station is increased. Therefore, the process station needs
