The Automation System Research Of Infiltration Product Line

The programmable controller technique and the robot technique and the calculator assistance design and manufacturing the technique is together been called modern industry by people to control three pay pillar greatly. Considered the advantages of PLC control and the Infiltration project's specialty, my dissertation chose PLC to deal with the Infiltration system 's automatic control。The thesis analyzed the meaning of Infiltration , what is called Infiltration is using inorganic or the organic chemistry liquid, using an appropriative equipments, sealing completely the casting tiny bore blemish to result in effectively under the particular craft request of seep into, raise the casting a qualified rate for produce. The Infiltration product line that can deal with Infiltration process now be widely used in automobile and motorcycle industry .But to now days domestic Infiltration product line have many kinds technique, large-scale enterprise using importation automatic equipments, but the middling-scale and small-scale enterprise manual control the system. Exist deadly safety problems. The produce rate is poor. Aimed at the Infiltration product line manual operation circumstance, the thesis analyzed the principle that using PLC technique to control the Infiltration product line automatically, put forward a kind of scheme of using PLC technique in the automation control of the impregnation process: initialization, impregnation, cleanout one and cleanout two processing .given out the software and hardware solution of the automatic control, using PLC to the control the Infiltration product line's water circuit electric circuit and gas circuit, resolved the Infiltration product line's problems: such as manual operation safety bad, operation difficulty, the hard precision control of time, producing an efficiency a low problem. Then used it to realize the ChongQing HongQi Vat Top Factory impregnation product line's automation construction project.Proposed the control system life cycle and the control system development life cycle concept in the thesis, tried in the development of control the engineering item, use some successful experience that the software engineering manage, carry on the valid management and control to the whole development of project, resolve some existent problem, such as the need definition, the system maintenance...etc. in the engineering development process. And applied this theory in the whole development process of project The project been divided into the stages, such as the control principle analysis,...
