Development of Drilling Ship Instrument Control System and Hardware-in-the-Loop Simulation Test

为有效提高钻井船生产过程火气安全切断的可靠性及船员的安全性,针对钻井船仪控系统工艺过程控制和安全切断的控制策略复杂度高,难以通过普通仪表测试,研制了具有网络冗余的分布式控制系统和采用具有安全等级的安全控制器搭建的钻井船安全仪表系统,并搭建了半物理仿真验证平台验证其控制逻辑的准确性。验证结果表明:该钻井船仪表控制系统样机的过程控制和安全系统的控制策略、关断策略安全有效,无线通讯和管理软件及报表分析、趋势预测等功能与实船需求相匹配;借助该仿真平台不仅可以优化控制效果还提高了测试效率。

In order to effectively improve the reliability of fire and gas safety shutdown and the crew safety in the drilling ship,aiming at the high complexity of process control and safety cut-off control strategy of drilling ship instrument and control system,which is difficult to pass the ordinary instrument test,the distributed control system with network redundancy and the safety instrument system of drilling ship built with safety level safety controller were developed.A semi physical simulation platform was built to verify the accuracy of the control logic.The verification results show that:the process control and safety system control strategy and shutdown strategy of the drilling ship instrument control system prototype are safe and effective,the functions of wireless communication and management software,report analysis,trend prediction and other functions match the requirements of the real ship.The simulation platform can not only optimize the control effect,but also improve the test efficiency.
