High speed aseptic brick drink filling machine has complex structures and many control points. There are not only the process control aiming to temperature, pressure, liquid level, flow, but also the motion control for speed and displacement of the packing machine. And the whole production process must be under tight control. Meanwhile, this system has requirements of stability and highspeed. Based on these characteristics, the control mode of upper and lower computer was confirmed. And control system was designed. It contained PLC, the kernel control part, and two independent control modules. The results show that realtime and high precision control can be achieved in high speed processing through the control system, and it provided convenience to workers for manipulating and monitoring the machine. The research findings can provide basis for the control system design of electromechanical equipments including many control points.
