RESEARCH AND PRACTICE CONTROL SYSTEM OF STEREO-STORAGE BASED ON THE PLC

摘要

With the fast development of globalization economy, workload of industrial automation increases exponentially which will lead to an increasing control demand, practically, effectively and reliably. In this paper, stereo-storage, an effective way to save space and time, has been chosen as an object to study. The stereo-storage mainly consists of a mechanical system and a control system. The mechanical system includes five layer shelves and motor drive (vertical lifting and horizontal feed) systems. The control system, referring to an operation part and a control part, has been paid close attention to this work. The display is a kind of the operation part which is a human-computer interaction platform; while the control part is made up of the PLC and the frequency converter. Testing the control system of stereo-storage demonstrates an enhanced performance and the control system have been proved to facilitate control and protection of the mechanical system.
