嵌入式终端上质量管理控制图的研究与实现

Research and Realization of Quality Management Control Chart on Embedded Terminal

控制图理论作为统计过程控制即SPC的核心,已成为了质量管理中的一种重要工具.控制图理论主要是应用数理统计的方法,通过对质量数据的处理来分析和判断工序是否处于稳定状态.将控制图理论与嵌入式技术相结合,研制了满足生产现场质量管理需要的集数据采集与统计分析于一体的嵌入式质量管理器.而数据的录入、保存与处理和控制图的生成与显示作为嵌入式质量管理器的重要功能,有必要单独研究.文章主要针对上述内容进行了研究和实现,解决了嵌入式质量管理器上的相关问题,为实现现场在线实时统计质量管理奠定了基础.

The theory of control chart, the key part of Statistical Process Control(SPC), has been an important tool in quality management. The state of process can be analyzed and judged by using control chart that adopts mathematical and statistical methods. The Embedded Quality Management Device has been developed to meet the needs of field quality management through the integration the theory of control chart with the embedded system. The Embedded Quality Management Device is an integrated one by integrating data acquisition with statistical analysis. Data writing, data storage, data disposal and creation and display of control chart are the main functions and so it is necessary to be studied separately. The paper deeply studies and realizes the contents above, and resolves the questions about the Embedded Quality Management Device. The results above make preparations for on-line real-time quality management.
