基于PLC的控制系统在机器人码垛搬运中的应用

介绍了机器人码垛搬运生产线的一个基于PLC的控制系统应用实例。该系统采用工控机和PLC组成上下位机控制系统,上位机主要进行指令控制、数据信息管理等,下位机主要负责系统运行中的逻辑控制。上下位机之间采用自由口通信模式进行数据通信,用户可以自己制定通信协议,使系统控制更加灵活和方便。实际应用表明,该控制系统可以实现自动码垛搬运,运行可靠、稳定。

Application of a PLC based control system in robot palletizing

This paper presents a PLC based application instance of robot palletizing product line. An industrial computer and a PLC exist in this instance, which constitute an upper and a lower computer control system. The functionalities of the upper computer are instruction control and information management, while the lower computer is responsible for logic control. The upper computer and the lower computer communicate through a free port and a user can devise a communications protocol by himself, which make system control be more flexible and convenient. Practical application indicates that such design can implement automatic palletizing, and also has such advantages as better reliability and stability.
