Z30130X31型钻床控制系统的PLC改造
摘 要:Z30130X31型摇臂钻床属于大型立式钻床，其传统的控制方式是利用继电器接触器原理控制。由于利用继电器接触器控制系统比较复杂，难于操作；因此本次设计是将其改造成为利用PLC控制，这样既可以提高生产效率，也可以增加其使用寿命。
首先通过对钻床工作原理的了解，然后对PLC的硬件和软件进行设计。根据钻床的工作要求选择合理的工作器件如：继电器，接触器等等，然后编写相应的程序语句表并绘制梯形图，再根据输入输出点数选择PLC型号，输入点数：22输出点数：17，所以本次设计选择FX2N-48MR型PLC并绘制硬件接线图；最后对程序进行模拟调试。

Z30130X31 drilling machine control system's PLC transformation
Abstract: Z30130X31-arm drilling is a large vertical drilling, the traditional control method is the use of relay contacts Principle control. The use of the relay contactor control system more complicated and difficult operation, therefore this design is its use of a PLC control, this can enhance the efficiency of production and can also increase their service life.
By drilling the first principle of understanding, and then the PLC hardware and software design. According to drilling requirements for the work of the work of a reasonable choice of devices such as: relays, contacts, etc., and then the preparation of the corresponding procedures and the mapping of ladder diagram sentences table, the light input and output points choose PLC models, the importation of points: 22 output points: 17, Therefore, this design options FX2N-48MR PLC and the mapping of hardware wiring diagram; Finally, the simulation debugging procedures.
Key words: PLC; motor; trip switch circuit breaker; control button control switch; work light.
