进口专用电液吊具控制系统研究与改造

Transformation and research on the control system of imported electro-hydraulic spreader

以进口专用电液吊具为研究对象,提出一种基于可编程控制器(PLC)的控制系统设计框架,实现对两种不同供电方式下吊具的控制。其多对象的适用性及内部电压的处理技术对类似控制工程有很好的参考价值。

Based on the electro-hydraulic spreader, a PLC-based control system design was put forward, to achieve the control in two different power-supply spreaders. Its applicability of multi-object and the handling of internal voltage control technology have a good reference value on similar projects.
