The Design And Realization On Hardware Flat Of Embedded Statistical Quality Management Device

Locale quality management is the important part of quality management, which provides support on data and information for quality decision-making. The effective control of locale quality data is the keys for an enterprise's quality management. Its effectiveness is mainly represented on authenticity, efficiency, utilization and other aspects of the data. But the present mode of locale quality management has many shortages, which mainly indicates the effectiveness of quality data and the utilization ratio of statistical methods: Out of date collection and process methods of data; low accuracy; Low transmission efficiency of data; Low utilization ratio of statistical methods, poor characters in initiative and real time, the method of statistical process control is not really be used, without relative quality pre-alert system which leads to quality fluctuate. Aiming at these problems, this article proposes to use Embedded Technology on site quality data management, designs and develops the Embedded Statistical Quality Management Device (ESQMD), which includes automatic quality data collection and statistical analysis as well as Internet transmission. ESQMD could help to make the management of locale quality data more standard, actualize statistical process control, and improve the efficiency of Locale quality data, advance the utilization ratio of statistical method. ESQMD is based the design of Embedded Technology. Aiming at the characters of the operating environment and its user, it guarantees the system could be fluently used in the production locale through high efficiency design of software and hardware. For the system function, the hardware platform could provide the peripheral interface for communication with site digital facility and enterprise quality data system, and achieve the automatic, quick and accurate collection and transmission of quality data. Internet applications could make real time statistic and analyze for collected data, issue quality pre-alert, alert information in time and help quality controller to accomplish the methods of statistical process control, and fulfill enterprise's requirement for locale quality management. In this thesis, the main reach is the design and achievement for hardware platform of ESQMD. Firstly, this article fulfills the system function design as per the enterprise's actual demand for site quality data management. It proposes the overall design plan for system hardware platform based on function requirement. Then, on the bases of this plan, it makes detailed design for the component parts of the hardware platform, which mainly includes the content of choosing MPU of System, Designing of Data communicating cell, storage cell and alarm cell. Etc. After that, the article discusses the achieving technique for hardware platform, and establishes cross compile environment for system Internet applications to make the realization of hardware function. Lastly, it briefly introduces the development work for the system applications, analyses the operation environment requirement and gives one system-working example.
