Process parameter recommendation system and method based on data collection

Abstract

The invention proposes a process parameter recommendation system and method based on data collection, belonging to the field of databases. The key points of the technical scheme of the present invention are: the data acquisition module is used to obtain the real-time operation status data of the equipment, judge the actual operation status of the equipment, obtain the time sequence process parameters and status parameter data of the current equipment production operation, and obtain the data collected from the production information management system. The identification information of the equipment, the identification information of the product, the bill of materials information and the yield information of the product; the data screening module is used to judge the operating status of the equipment according to the cycle time parameters of the equipment operation, and to screen the equipment according to the normal production time period of the equipment Time-series process parameters and state parameter data are formatted and stored according to equipment identification information and product identification information; the automatic recommendation module is used to extract the data group that has completed process parameter optimization in the database according to the input product identification and equipment identification , as the recommendation result.

Description

technical field [0001] The invention relates to database technology, in particular to a system and method for recommending process parameters based on data collection. Background technique [0002] Injection molding is one of the methods widely used in plastic processing at present. The quality of injection molded products is affected by molds, materials, process parameters and environmental factors. In actual production, the production conditions of molds and materials are relatively fixed, and there are many nonlinear dynamic and uncertain factors in the influence of molding process parameters on product quality, so it has always been an important task in this field to improve the quality of injection molding products by setting process parameters reasonably. Big problem. Therefore, aiming at the process characteristics of injection molding and taking process parameters as the research object, there is a very urgent practical demand to achieve the purpose of improving th...

Problems solved by technology

At present, experts and scholars in this field have achieved a large number of research results for the optimization of process parameters, and have also produced various expert systems, but these results and systems are only for a certain type of injection molded parts or specific production environments and equipment. research and results, and requires production personnel to have profound theoretical knowledge or the system contains complex algorithm models, and lacks the support of huge amounts of data generated in actual production scenarios, and cannot adapt to various product types, equipment in different health states, and complex systems. The actual production environment has great limitations
