  • 加快了操作人员对于潜在问题的响应速度

应用

监控废纸脱墨过程

客户

比利时纸浆和造纸厂商Stora Enso Langerbrugge N.V.

挑战

类似Canfor的石灰窑运营易受控制回路之间的相互影响,这是运营条件不佳的原因。

Stora Enso Ghent车间通过中央控制室监控废纸脱墨过程。操作人员在操作员屏幕前执行监测和控制任务、处理报警、运行测试并执行日常操作程序。由在车间现场工作员工为操作人员提供信息支持,现场人员的工作包括清洁设备、执行维护、处理堵塞和支持生产启动/停止。

但是,夜班期间只有一个操作人员。这个操作人员不能离开控制室去工厂现场执行任务,因为这将会带来错过警报或无法及时响应重要事故的风险。操作人员必须坚守控制室,这将无法最大化地发挥他们的能力或提高工作满意度。Stora Enso需要一种能够让操作人员离开中控室并可以持续查看过程报警的解决方案,以便能够识别出问题并采取适当的纠正措施。

解决方案

将车间的废纸脱墨过程升级至艾默生的DeltaV™分布式控制系统为该公司提供了部署无线技术以提高操作人员效率的机会。借助于配有DeltaV远程操作站应用的加强版苹果 iPad4 平板电脑,废纸脱墨过程的Wi-Fi网络可以提供“热点”,以便访问过程操作。

这一解决方案可以帮助操作人员执行巡检任务,同时将中控室的过程状态信息发送至iPad。最终,他们可以及时处理报警,同时执行车间的日常巡检任务。

由于iPad易于操作并且一旦损坏容易替换,因此选择使用iPad作为工具。无线网络由10个工业访问点和1个无线LAN控制器以及一个网络管理应用组成,以便覆盖室内和室外两个楼层。无线网络采用AES 128位数据加密,因此非常安全并且可以持续监控网络的完整性。

通过查看实时信息,操作人员现在可以更快地处理问题。移动工作站应用可以直接将观察结果记录至控制系统,避免转录错误。操作人员可以独立地执行过程操作,即使操作人员位于现场区域,也可以启动或执行工作指令。一个操作人员即可执行多项任务,节省了他们在控制室和过程装置之间的往返次数,从而提高了操作人员的工作效率以及工作满意度。工作效率的提高有助于减少运营成本,客户不到六个月即收回了投资。
