近日，刚结束为期一个月科考任务的"向阳红05"船，正进入新任务的准备阶段。船员挥汗如雨，吊 机、车辆、船舶维修等工作有序推进，各部门沟通协调的电话声不绝于耳⋯⋯这一切，都是为第二天10 时准时启航做准备。 23时50分，一声刺耳的警报划破集控室内的平静。经检查，机舱集中监控报警系统瘫痪，所有数据 丢失，PMS（配电功率管理系统）也失效了。 如果把机舱比作船舶的"心脏"，那PMS系统就是这"心脏"的"神经中枢"，控制着发电机组并网运 行、负荷分配及关键设备供电。但该设备厂商远在上海，不可能第一时间到位。若无法及时排除故障， 就意味船舶失去稳定动力，无法正常航行，启航时间也将被迫推迟，后续连锁反应难以评估。 当日值班领导接到突发故障的报告后迅速到场，会同船舶讨论研判故障现象，初步梳理出三种可 能：一是集中监控系统UPS（不间断电源）故障，导致监控系统供电异常；二是监控系统核心部件模块 故障，造成系统瘫痪；三是系统软件本身出现问题。经检查，UPS供电正常，核心部件性能理论上较为 稳定，而PMS系统的电控箱内指示灯却异常闪烁"F"红灯。此类深层故障以往极少遇见，排查工作一度 陷入僵局。 就在众人一筹莫展之际，轮机长吴 ...
