基于S7-1200的全液压动力猫道机控制系统的设计与实现

根据石油钻机自动上下钻具作业要求设计了猫道机自动控制系统,构建了S7-1200 PLC与便携式操作箱和工业监控设定触摸屏之间的网络架构,通过数字液压轴控制器实现了主动作液压阀的精准控制,在此基础上对阿托斯数字液压轴控制器参数设定和猫道机自动运行过程进行阐述,编写了主站PLC与触摸屏的软件程序,同时对监控设定触摸屏画面组态进行说明。通过主站PLC和数字液压轴控制器对现场数据的采集分析处理,实现了钻具快速、平稳、自动上送至司钻台和下放的控制执行功能。

Design and Realization of S7-1200-based Fully Hydraulic Catwalk Machine Control System

Based on the operational requirements on automatically loaded/unloaded drilling tools of oil rigs, this paper constructs a network architecture between S7-1200 PLC, a portable operation box and a touch screen for industrial monitoring setup, and through a digital hydraulic axis controller implements precious control of the main action hydraulic valve. Furthermore, it expounds parameter setting of Atos digital hydraulic axis controller and the process of automatic operation of the catwalk machine, compiles software program for main station PLC and touch screen, and explains the image configuration of the surveillance setting touch screen. Through acquisition, analysis and processing of field data by the main station PLC and digital hydraulic axis controller, we realize control function of fast, stable, automatic feeding of drilling tools to the driller's station as well as their load-off.
