问可编程控制是由什么控制系统转换而来的

in the programming part of the thesis, we used trapezoidal chart programming. it simplifies the control demands and is convenient for code modifying. this plc control system of the multi-style fountain not only implemented the function of auto-transfering the spraying style, but also improved the safety and the reliability of the system, which has value on engineering application.

可编程控制可能就是PLC来控制设备的系统吧?PLC是由单片机组成的控制系统转换而来的。
