An extremely reliable remote control system for subsea blowout preventer stack is developed based on the off-the-shelf triple modular redundancy system. To meet a high reliability requirement, various redundancy techniques such as controller redundancy, bus redundancy and network redundancy are used to design the system hardware architecture. The control logic, human-machine interface graphical design and redundant databases are developed by using the off-the-shelf software. A series of experiments were performed in laboratory to test the subsea blowout preventer stack control system. The results showed that the tested subsea blowout preventer functions could be executed successfully. For the faults of programmable logic controllers, discrete input groups and analog input groups, the control system could give correct alarms in the human-machine interface.
基于现成的三重模块冗余系统，开发了一种用于水下防喷器组的极其可靠的远程控制系统。为了满足高可靠性要求，使用了各种冗余技术，如控制器冗余、总线冗余和网络冗余，来设计系统硬件架构。使用现成的软件开发了控制逻辑、人机界面图形设计和冗余数据库。在实验室进行了一系列实验来测试水下防喷器组控制系统。结果表明，所测试的水下防喷器功能可以成功执行。对于可编程逻辑控制器、离散输入组和模拟输入组的故障，控制系统可以在人机界面中给出正确的报警。
