【Abstract】 In view of the working principle and technological requirements of the miniature pressers, this paper primarily introduces the automatic controlling process. Furthermore, it provides the hardware design of the controlling system and the external wiring diagram of the pressers, distributes I/O ports and the internal relay resources. As for the software design, the paper takes advantage of the sequence controlling design programming, and designs the ladders diagram of the automatic controlling system with this method.更多还原
