PLC液压控制系统在长钢轨引导车上的应用

Application of PLC in Control System of the Long Rail Guide Car

摘要: 本文提出了长钢轨引导车的液压控制系统，实现了长钢轨引导车各功能的准确控制。在该车的连接梁相对水平度的检测中，采用三模冗余容错技术，提高数据采集的可靠性。在PLC对开关量进行控制的基础上，运用PID调节，实现了对模拟量闭环控制。

Abstract: In this paper, hydraulic control of the long rail guide car is proposed, achieving the precise control of the long rail guide car’s each function. The detection of connection beam relative levelness has been improved reliability based on the three die redundant fault-tolerant technology. On the basis of the PLC’s controlling, the amount of the switch and the use of PID regulation, the analog closed-loop control is realized.
