The design of control system of small warehouse PLC
Abstract：With the rapid development of modern production scale and the continuous prosperity of social substance, to store goods in the planar storehouses can’t meet current demands any more. While the automated stereo storehouse with small floor space and excellent space utilization have been an important and indispensable link in the production logistics system, so the research of the stereo storehouse is also going deep. According to the work flow and control requirements of the stereo storehouse in this paper, I have designed an automated stereo storehouse control system with using Siemens S7-200 PLC as a controller. The system takes the stepping motor as an actuator to realize the point to point control for the stacker. It can implement inventory / delivery process in the stereo storehouse by automatic / manual control mode. You can use the touch screen to complete the whole operation on the storehouse. Surveys show that the system is reliable, flexible and practical. The study can be not only applied to the control of industrial field, it also has a certain reference significance of training and teaching research for operation personnel in the enterprise.
