Reciprocating washing machine control system is mainly divided into two categories, one is the PLC technology, and the other is the microcontroller technology. One misunderstanding that needs to be corrected is that the microcontroller is cpu and the PLC has no CPU. This statement is wrong. PLC has its own CPU module. PLC is relying on the current sensing technology. With the photoelectric sensor switch, the pressure of the brush is converted into an electric signal and transmitted to the CPU to sense the shape of the body. The SCM technology relies on photoelectric sensors, which convert the identified obstacle information into electrical signals for transmission to the CPU. The advantage of PLC control system is easy maintenance, rapid development speed, strong anti-interference ability, disadvantages are more expensive than SCM, occupying a larger space than SCM; the advantage of SCM is small footprint, low price, the disadvantage is long development cycle, poor anti-interference ability . The world's high-end car washing machines use PLC or SCM control systems.
