摘要
以MCGS组态软件和ABBAC500系列PLC为核心,建立了具有数据采集、数据处理、设备执行以及上位机显示功能的监控系统。系统以船舶压载舱液位、船舶吃水、压载泵进出口压力等参数作为监测对象,通过使用PLC控制压载舱阀门、压载泵等设备,运用模糊PID算法进行阀门控制。利用MCGS组态软件来开发上位机监控界面,主要包括系统的主控界面、参数的设置界面、历史数据报表和报警记录等。通过这些界面,用户可以实时监测压载水调节过程中的船体浮态参数和设备的运行状态。试验表明,上位机呈现的画面直观、操作简单,具有良好的人机交互性;下位机程序运行稳定;整个系统能实现预期的功能。
With MCGS configuration software and AC500 series PLC from ABB as the core, the monitoring system integrating the functions of data acquisition, data processing, equipment execution and host computer display is built. The monitored objects of the system are the parameters of water level of ballast tank of ship,4 - corner of draft,inlet and outlet pressures of ballast pump; the ballast tank valves, and pumps, etc. , they are controlled by PLC and fuzzy PID algorithm. The monitoring interface of host computer is developed by using MCGS configuration software, mainly includes main control interface, parameter setting interface, historical data report and alarm records, etc. The hull floating parameters and operational status of the equipment in regulation process of ballast water can be monitored in real time through these interfaces. The tests show that the displays provided in host computer are intuitive, the operation is simple, the man machine interaction is excellent ; the program in slave computer is running stably ;thus the overall system implements the expected functionality.
