Research On Computer Aided Quality Assurance System Of Boiler And Pressure Vessel Manufacture

The security of boiler and pressure vessel running is an important problem that the whole community pays attention to. The manufacture quality affects boiler and pressure vessel 's running security. To improve the quality of boiler and pressure vessel's manufacture quality, in our country, the manufacturer qualification examination system put into effect. To get the produce license, manufacturer must establish a feasible quality assurance system. In fact, for some reason, the quality assurance system can not be implemented strictly. The only use of quality assurance system is for superior or user's examination.How to make the quality assurance system be implemented strictly and right by technology methods is a greal problem in dire need of resolving for the manufacturer and management department. As a part of the project, Research on computer aided quality assurance system of boiler and pressure vessel manufacture, which is supported by (he Zhcjiang provincial bureau of science and technology, the paper aimed at the problem discussed above, and research results arc as follow:1) By studying the quality assurance of boiler and pressure vessel's manufacture, a quality assurance system mode fitting for native manufacturer is putted forward in this paper and the quality control flow are designed in detail.2) Based on the quality assurance system mode, the full structure of Computer Aided Quality Assurance System (CAQA) is studied. The MS SQL S1ZRVIIR is used as DBMS, DclphiG.O as development tool in the CAQA system. The three-tiered application program architecture is adopted by the system. The software can aid manufacturer manage the quality plan, quality control, quality evaluation and synthetical quality information.3) After the analysis of the strongpoint and shortcoming of all kind of CAPP system, the CAPP desktop system is adopted to manage.the process document. Based on the characteristic of (he boiler and pressure vessel produce process, the CAPP desktop's structure and functions arc designed. The CAPP desktop is an advanced and useful tool for person designing process.4) The tree-like data structure is raised to organize the products and parts' complicated information, and its module is developed. It can make the management more clear and visual. The system also offers the functions to manage (he version of (he part's process document.5) The manufacturer's workflow management is designed and developed. The all kind of information in manufacturing procedure arc integrated by workflow management. According to the various types of tasks, roles and rules, disposing process of information mission was well defined.
