The Control Researsh of PLC-based’s Teaching Excavator

Abstract
Programmable Logic Controller ,also called PLC, is a microprocessor-based, integrated computer technology, automatic control technology and communications technology to develop a new, common control device. This paper presents the control research of PLC-based’s teaching excavator.In accordance with the requirements of the teaching excavator control system, the use of the power features of the PLC to achieve the use of PLC’s control system for the teaching excavator control. This article also from the PLC control principles, methods, as well as the realization of the control system design process for detail. Through practice, the results show that the system design reasonable, high reliability, to achieve the desired goal and achieving good results. In this paper, two aspects of hardware and software for a specific design.
