QZT4-20 artificial brick shaper PLC
automatic control system design
Abstract: According to the technological requirement of QZT4-20 Brick Forming Machine, we adopt PLC to automatic control it, and mainly accomplish the design of hardware and software. The hardware includes choosing PLC, deciding the input and output component of PLC, designing the operating board etc. The software consists of automatic control program for production, manual program for testing and breakdown warning program. The quality of the designed software directly affects the performance of the system. Hence the focal point of this design is the design of software. In the light of the diversity of products, we have adopted model to design the soft, which enhanced the flexibility of control. In order to assure the reliability of this system, we have used PLC to design automatic warning program, which realized the voice warning and auto-display the breakdown point.
