基于计算机技术的工序质量控制系统研究

Study on Process Quality Control System Based-on Computer Technology

针对企业设备陈旧、加工手段落后致使产品质量不高的状况 ,在分析工序质量控制观念、方法的基础上 ,提出了应用计算机技术进行在线控制的构想。对控制系统运行所依据的数理统计理论及控制方法与计算机技术结合的可行性进行了分析。以经济实用性、现场可操作性为出发点 ,将计算机技术、在线检测技术、传感技术、网络与数据库技术及质量控制方法相结合 ,使所开发出的系统能够实现在线工序质量控制。该系统可用于对单工序、多工序及区域性的质量控制并可对工序质量及系统自身进行可靠性分析和经济性分析。

Presently, for most enterprises the situation is that the obsolescence equipment and technology resulting in the low product quality, so based on the analysis of the process quality control concepts and methods, the assumption of computer-based on-line process quality control is put forward.The feasibility to operate the control system according to the statistics theory, control method and computer technology is also analyzed.On the view of economy,practicability and local maneuverability, on-line process quality control is achieved by the combined usage of computer technology, on-line inspection technology, sensor technology, internet and database technology together with quality control method.This system can be used to control quality not only for the single process but also the multiple processes and territorial, the feasibility and economy analysis for process quality and the system itself also can be implemented.
