Advanced Alarm Systems: Display and Processing Issues
1995
This paper describes a research program sponsored by the U.S. Nuclear Regulatory Commission to address the human factors engineering (HFE) deficiencies associated with nuclear power plant alarm systems. The overall objective of the study is to develop HFE review guidance for alarm systems. In support of this objective, human performance issues neediig additional research were identified. Among the important issues were alarm processing strategies and alarm display techniques. This paper w i l l discuss these issues and briefly describe our current research plan to address them.
Prioritizing Alarms in Real-Time: Intelligent Alarms Advanced System
Journal of Mechanics Engineering and Automation, 2015
During the operation of complex process, such as oil production or refining, abnormal situations may occur, leading to an alarm flooding. Alarm flooding is the signalling of a large number of alarms in a few minutes, in such a way that it is impossible for the operator to attend to all alarms. On these occasions, it is usual that the operator leaves the alarm summary list and gets an analysis of the plant through the screens of the DCS (digital control system), seeking to understand the situation. The alarm summary list ceases to be a useful tool. In such cases, the operator might have the aid of a filter that would present the highest priority alarms and other information associated with them, enabling him to gain a better knowledge of the situation. This paper describes the interface of a system aimed to help the operator to have a more comprehensive knowledge of the process (a better situational awareness) during process upsets that cause alarm flooding, recovering the utility of the alarm layer to the safety of industrial processes.
Alarm Systems
Simulator-based Human Factors Studies Across 25 Years, 2010
In any control room alarm indications are installed to present particularly important information to the operator about process deviations, plant disturbances and critical plant conditions. It is the operator's responsibility to observe the patterns of warning and alarm indications and to deduce the correct actions which are needed.
An Expert System for Monitor Alarm Integration
Journal of Clinical Monitoring and Computing, 1999
Objective. Intensive care and operating room monitors generate data that are not fully utilized. False alarms are so frequent that attending personnel tends to disconnect them. We developed an expert system that could select and validate alarms by integration of seven vital signs monitored on-line from cardiac surgical patients. Methods. The system uses fuzzy logic and is able to work under incomplete or noisy information conditions. Patient status is inferred every 2 seconds from the analysis and integration of the variables and a unified alarm message is displayed on the screen. The proposed structure was implemented on a personal computer for simultaneous automatic surveillance of up to 9 patients. The system was compared with standard monitors (SpaceLabsTM PC2), using their default alarm settings. Twenty patients undergoing cardiac surgery were studied, while we ran our system and the standard monitor simultaneously. The number of alarms triggered by each system and their accuracy and relevance were compared. Two expert observers (one physician, one engineer) ascertained each alarm reported by each system as true or false. Results. Seventy-five percent of the alarms reported by the standard monitors were false, while less than 1% of those reported by the expert system were false. Sensitivity of the standard monitors was 79% and sensitivity of the expert system was 92%. Positive predictive value was 31% for the standard monitors and 97% for the expert system. Conclusions. Integration of information from several sources improved the reliability of alarms and markedly decreased the frequency of false alarms. Fuzzy logic may become a powerful tool for integration of physiological data.
Intelligent alarm management
2011
An ergonomic problem for the plant operators has appeared in the modern electronic control systems, in which configure an alarm is very easy. We present a methodology and an intelligent software tool to manage alarms and make early fault detection and diagnosis in industrial processes, integrating three techniques to detect and diagnose faults. The three techniques use available information in industrial environments: The alarms of the electronic control system; the fault knowledgebase of the process, formulated in terms of rules; and a simplified model used to detect disturbances in the process. A prototype in a Fluid Catalytic Cracking process is shown.

Alarm Grouping
(1) “Alarm Group” defines that which PC displays which alarm.
(Ex.) In case of Hot Strip Mill,
Group Name : FCE (Furnace Group)
: RM (Rough Mill Group)
: FM (Finisher Mill Group)
: DC (Down Coiler Group)
: CV (conveyer Group)
(2) Alarms are stored as the Tag Information in the HMI database.
Alarm group is defined in the Tag Information.
