基于MCGS的船用LNG燃料安防控制系统的设计

Marine LNG Fuel Security Control System's Design Based on MCGS

该系统基于西门子S7-200 PLC[1]和MCGS触摸屏[3],实现了系统用户管理;液位、压力、温度等传感器数据的采集及处理;故障检测及报警与保护;阀门的控制;远程人机交互界面等。以PLC为控制核心的船用燃料LNG安全控制系统,提高了控制系统本身的安全可靠性,控制性能和保护性能更加完善;使控制系统的硬件组成和线路更加简化;操作和维护更加容易。

The system based on Siemens s7-200 PLC and MCGS touch-screen implements the system user management.It can acquire and process the date of Liquid level,pressure and temperature sensors detect Fault,alarm and protect.It can control the valves and control Remote human-computer interaction interface,etc.The system can greatly improve the safety and reliability of the control system itself.The control and protection performance is improved.The system hardware and circuit are simpler.The operation and maintenance are more easitv.
