The Study On Computer Control System Of Multitemperatual Zones Refolw Soldering

Relating to practical manufacturing demands, the paper studies on designs and EMC problems of Multitemperatual Zones Refolw Soldering computer control system .The system adopts the structure of superior/below position operator.There are four parts of below position : pre-data gathering module, speed measuring module, speed controlling module, On-Off outputting module . Pre-data gathering module achieves the collection and communication of sixteen-route temperature signal .Speed measuring and controlling module realizes the control of Refolw Soldering transfer speed by manipulating transducer . On-Off outputting module fulfills calefaction control of calefaction tube by solid state relay. Above position operator software programs by Delphi, and realizes PID parameter automatic timing and no-oversnooting temperature control .Software has friendly interface ,convenient operation, complete functions. Furthermore , the paper studies system's EMC peoblems , and do EMC tests on series connection and power circuitry . The result of system running indicates:ststem has fine stabilization, jointing quality well, and has high practical value and extending significance.The fields of the paper involves multiple techniques of electron ,computer,autocontrol, MCU ,EMC . The innovation and key problem to this thesis is to ascertain PID tunning rules by a great deal of experiments,study syetem's EMC problems . The paper has referenced value to information technology facility's design.
