PLC课程设计(电镀车间专用行车PLC控制系统设计)本文以电镀自动生产线控制系统设计为研究对象，以其电镀专用行车为控制对象，对其电镀的工艺要求和控制要求进行了分析，采用理论研究的方法，设计了一套基于PLC的电镀车间专用行车自动控制系统。本系统选用三菱FX2N-64MR-001型号的PLC来进行控制，通过PLC输出信号接触器的触点动作，来控制三台异步电动机的运行，从而实现对行车的水平运动和吊钩的垂直运动的控制，考虑到电镀、上升、下降等运动时行车和吊钩需要准确停位。在程序设计时为了便于对设备进行调整和检修，设计了手动程序以实现对行车和吊钩的点动控制，对于自动控制程序的设计，其工作过程是典型的顺序控制，采用步进指令能很好的实现对其控制。通过软件仿真可以看出所设计的控制系统很好的实现了电镀的工艺要求和控制要求，可以方便完成自动和手动之间的切换，体现出
PLC控制系统具有调试方便、适应性强的优点。

ABSTRACT
The electroplating automatic production line to control system design to study, with its specialized operations to control traffic. the electroplating technology and control of the claim was analysed and the theory of the research methods, design a web based on the plc electroplated impression of the special traffic control system; The system for mitsubishi fx2n - 64mr -001 kind of the plc to control, the output signal of the plc contacts with some action to control motor three asynchronous operation, the level of the motion and the hook vertical motions of the operations, rising and falling, the motion and the hook to the right stop. in programming, to facilitate the adjustment of equipment and design a manual procedures for the implementation and hook at the control, the automatic control of the design, it is typical of the order of control and use the step into the instructions to the very good with the controls. Through software simulations can see that the system of the electroplating technology and control, you can easily finish automatic and manual switch between that of the plc control system for the adaptable.
