In order to produce some higher accuracy and quality castings,one of the efficient measures is to improve the automatic level of the pouring machine.An auto monitoring system was developed aiming at the requirements of pouring machine manufacture in Changzhou.This system was composed of PLC,touch screen and some sensors.The PLC was used as the controller,which received the sensors signals and output the control signals to realize the pouring machines auto control.The touch screen was used as the monitor equipment,which could be used to set some different technological parameters such as tilting speed,pouring time and user permissions etc.In this system,not only the advanced measurement technology was used,but also the advanced control technology such as fuzzy PID was applied in the constant temperature control of the aluminium equipment.By running,it is shown that the system is very safe and reliable,and it has realized the control demands of the pouring machine and improves the existing performance of manual pouring machine.
