有限状态机模式下的弯管机控制系统设计
|
摘要
为了实现弯管机PLC控制系统的数控编程控制的功能,基于有限状态机提出了弯管机控制系统的一种新设计方法。该方法运用有限状态机的原理将弯管机执行机构的物理动作抽象封装为若干个状态。PLC控制程序通过触摸屏获取外部指令,并以外部指令作为状态转移的触发条件来实现状态之间的转移,状态的转移过程就是管件的加工过程。同一系列所有品型管件的加工过程,都可根据管件的加工工艺图纸和状态转移图在触摸屏上输入指令码串设定,不需逐一编写控制程序来实现。在实际应用中该弯管机控制系统达到了数控编程化加工的能力,满足了管件小批量多品种生产的需要。
This paper proposes a new design method for the pipe bending control system,which realizes the functional scalability of PLC control system of Pipe Bender.This method uses the principle of finite state machine to encapsulate the physical action of the actuator of the pipe bender into several states.Through the touch screen,the PLC control program obtains the instruction which triggers the state transfer.This is the process of the pipe manufacturing.The proposed system has the ability of NC programming and processing and satisfies the need of small batch production of pipe fittings.
