Methods and apparatus to detect root causes of alarm patterns in process control systems

Methods and apparatus to detect root causes of alarm patterns in process control systems are disclosed. An example method includes retrieving process control data generated in a process control system during a historical period of time. The process control data includes alarm data associated with alarms activated during the historical period of time. The example method also includes generating an alarm activation timeline for the historical period of time. The alarm activation timeline includes icons representative of the alarms to visually represent a temporal relationship of activation of the alarms, where one of the icons is representative of an alarm that is no longer active. The example method further includes storing the alarm activation timeline in a database. 公开了用于检测过程控制系统中的警报模式的根本原因的方法和装置。种示例的方法包括获取在历史时间段期间在过程控制系统中所生成的过程控制数据。过程控制数据包括与在该历史时间段期间激活的警报相关联的警报数据。该示例的方法还包括针对历史时间段生成警报激活时间线。警报激活时间线包括代表警报的图标，以便可视地表示警报的激活的时间关系，其中，这些图标中的个图标代表不再有效的警报。示例的方法还包括将警报激活时间线储存在数据库中。
