海洋钻井平台是海洋油气勘探、开发的主要设备.但是目前,我国使用和制造的海上石油钻井平台中的控制系统都是采用国外产品且造价昂贵,并且控制系统中控制信号的输出和传感器信号的输入大多为模拟信号,未采用专门的运动控制模块,从而导致平台升降控制精度较低.为了解决这个问题,提出并且设计了一种基于三菱Q系列PLC的自升式石油钻井平台控制系统,采用卷扬机代替昂贵的齿轮带动平台升降,利用Q系列PLC和运动控制器共同控制伺服放大器来实现对伺服电机的控制,有效地提高了升降控制精度.经实际证明,本控制系统能够有效并且精确地实现平台的控制功能,相比现有的平台控制系统,节省了大量的经费开支.%Marine drilling platform is the main equipment of marine hydrocarbon prospecting and developing. But at present, the control systems of the drilling platform usually use foreign products in our country,these are very expensive,and in the control system,the output of control signal and input of sensor signal is mostly analog signals, without using special motion control module, these cause platform control precision is low comparatively. In order to solve this problem, it puts forward a control system of jack-up drilling platform based on PLC of Sanling Q series and designs a new mechanical model. It adopts hoist instead of expensive gear. PLC of Sanling Q series and motion controller common control servo amplifier to achieve servo motor control. These improve the lift control precision effectively. The actual proof is that the control system can effectively and accurately realize platform control functions. Compared with the existing control system,it has saved a great deal of funding.
