Analysis And Mining On Production Quality Data Of Vehicle Components

Vehicle components quality data is the base of quality management,reflecting the production and manufacturing level of manufacturer.For utilizing vehicle components quality data conveniently and effectively,analyzing and mining the information from quality data,the article researchs and designs a solution,which includes vehicle components quality data centralized management system and data analysis and mining methods.The article designes quality data front-end collector and quality data centralized management software,which constitute a quality data centralized collection system for acquiring quality data.Quality data front-end collector,network electric column instrument,was constituted by AIR or LVDT instruments with network.It's based on STM32 MCU.It sends quality data to server as a client;quality data centralized management software collects all clients' quality data as server.It connects quality data with K Area,saving Q-DAS,Excel,etc.formats.In quality data analysis and mining part,using statistical process control theory evaluates production process by analyzing and mining quality data.Analyze and mine the hidden information in quality data,discover the possible problems in production process,and give early warning and guidance to form closed-loop management.The process capability index of production equipment is increasing in practical application.Managers from different levels can acquire situation of production process directly.The defective rate is decreasing,at the same time the output capability is increasing.
