In this paper it is used that the modem closed-loop AC servo-system controlled by PLC and transducer.Light-electricity sensors are used to measure displacement of the hay stacker．They are analyzed，which include work process，the way of recognizing the site and the running control in the hay stacker system.the S7-200 PLC is used to the micro-controller in the automated storage,and gives a key part of the program. In order to monitor and manage the operation of tridimensional warehouse status，with the input of configuration software for the operation of tridimensional warehouse has a real．time monitoring system．The system is capable of on-site data collection and processing，the operator could launch the monitoring system to get areal-time updates of the working status of the warehouse，to ensure a safe operation and imme
