The invention discloses a method for reducing misjudgment of a line stop reason. The method comprises the following steps: acquiring line stop data of a process of manufacturing a product through a data acquisition unit; judging whether the reason of line stop is a material shortage reason and / or a quality reason or not through a line stop reason judging unit; collecting historical line stop dataand recent change records of the process, historical operation data and maintenance records of equipment, material inspection records and offline records, recent change records of manufactured products, line stop data before and after change, process post line stop data and operator training record information; the analysis unit is combined with the steps S1 to S3, the data acquisition unit collects information of the data units and the proportion of the influence of personnel operation factors, equipment factors, material factors, design changes and procedure adjustment on line stop, and thekey reason of line stop is comprehensively estimated. Therefore, the problem of low efficiency of manual judgment of the line stop reason is solved, and the accuracy of judgment of the line stop reason is improved.
Description
technical field [0001] The invention relates to the technical field of industrial production, in particular to a system and method based on reducing misjudgment of line stop causes. Background technique [0002] In the assembly line production process of manufacturing enterprises, each position and link of the assembly line needs to be stopped (short-term stop line) frequently due to various abnormal reasons. Stopping is one of the important reasons that affect shift productivity and production efficiency. In order to reduce production waste and sum up production experience to improve efficiency, the time point and frequency of line stop are collected through the point-stop switch on the linkage production line, and the reason for line stop is required to be clearly selected for each line stop, so as to target product producibility Or production process and other aspects to improve, improve production quality and efficiency. [0003] At present, the common practice in the p...
