ABSTRACT
Steel tube is widely used as a sort of metallic material in industry and has also contributed much to the national economic development. In this paper, on the basis of the current situation of research on steel tube's measure, weight, pinstamp, band, stencil system both here and abroad, with the aim of researching and developing the measure system for 2nd product line in Tianjin Pipe Corporation,
technological process of steel tube and the international standard API are introduced. Then the current situation of research and problems on MWBPS system in China are described. And also, the necessities of the improvement of measure system are explained. Finally, the source of this project and the main contents as well as the significance of this paper are mentioned.the design requirements of this system are presented. Then,according to the system9 s integral structure, the author depicted the design of relevant measure subsystem, step system and etc,including the components, working process of the system and the precautions whendesigning. Finally, The whole design of the control system and software are alsopresented And the major hardware parameters. PLC program method and thecharacters of S7400 series are introduced in brief. The test strategy of the PLC program is also put forward. Finally, the testing strategy of the up-lever computer software and the characters of the monitoring control system are put forward. The expressi
