【摘要】 数字化检测是企业提高检测效率与检测水平的重要手段之一,因而逐渐受到企业的重视。检测数据的获取、管理与统计分析是企业实现数字化检测的关键技术与基础,因而对于企业提高产品质量、快速响应市场具有重要的意义。论文在总结企业生产现状与主要问题的基础上,分析了数字化检测环境下数据管理与分析系统的用户需求,设计了系统应该具备的功能结构,建立了数字化检测数据管理与分析系统的体系结构。针对企业生产检测数据采用数字化检测、人工管理和分析的情况,结合企业对检测数据电子化管理的需求,以三坐标测量机为例,实现了数字化检测数据的直接导入。根据导入系统中检测数据的特点,应用XML技术实现对检测数据模板的定制功能,实现了以往手工填写的质量单据的电子化输出。根据检测数据的特点与形式,并结合企业产品管理的特点,应用基于BOM的检测数据组织管理方法,实现了检测数据的组织与管理。针对企业多品种、小批量的生产情况,对检测数据缺乏先进统计分析的质量管理现状,建立了一种改进的统计过程控制方法。该方法可以从生产过程的早期即建立稳定的控制界限,较好地解决了传统统计过程控制方法难以应用在小批量生产条件下的问题。通过实例验证,证明了改进方法的有效性和可行性。在上述研究的基础上,开发了原型系统,通过试运行,证明该系统在实现检测数据电子化管理、小批量统计分析等方面满足企业的实际需求。

【Abstract】 Digital inspection is one of the most important technologies for the enterprise to improve efficiency and level of measurement. The acquirement, management and statistical analysis of the metrical data are the key and basic technologies to carry the digital measurement into execution. Thereby, it is significant for the enterprise to improve production quality and to make rapid response to market.In this paper, the enterprise’production status and primary problems are investigated and summarized; the users’needs of data management and statistical system in the digital inspection environment are analyzed. Successionally, the structure of digital measurement and data analysis system is designed, and the functions should be included in this system are analyzed.In this system, data obtained from digital equipment is also dealt with digitally. The CMM (Computer Measuring Machines) is taken as an example to illustrate the process of direct access of digital measurement. According to the characteristic and structure, XML (eXtensible Markup Language) technology is applied to accomplish the customization function; thereby the data can be output in electronic form instead of manuscript used before. And when the trait of the production management is also considerate, the BOM (Bill Of Materials) technology is applied to accomplish organization and management of the measurement data.As the multi-specification & small volume production becomes more and more popular, a new statistical process control method is proposed. This method can set the steady control limit at the beginning of the product process, so the problem that the traditional statistical method cannot be applied in the small batch production is solved better. This new method is proved correct and effective by an illustration and the compared result with the other statistical method.Based on the research above, the prototype system is developed, which is proved effective in the aspect of electronic management for the measurement data, the form customization function and the statistical analysis in the small batch production.
