报警系统是操作员界面的重要组成部分，用于自动监测工厂状态偏差，并吸引工厂操作员注意需要他/她干预的变化。设计一个高效的报警系统，帮助操作人员快速识别异常原因并对情况做出反应，是电厂安全运行的一项重要工作。在工程设备和材料用户协会（EEMUA）出版的EEMUA 191指南中，提出了工厂报警系统设计和评估的一般原则。在此基础上，提出了工厂报警系统的系统化设计方法。在设计阶段，根据因果分析，选择一组报警源信号。为了使报警系统合理化，我们准备了防止重复报警抑制的对策。对于所设计的报警系统的评价，我们参考了EEMUA 191指南提供的标准以及人工操作模型的故障识别时间等指标。并以某锅炉厂模拟器报警系统为例进行了设计。评价结果表明了该方法的有效性。
An alarm system forms an essential part of the operator interfaces for automatically monitoring the plant state deviations and attracting the plant operator's attention to changes that require his/her intervention. To design an efficient alarm system that helps operators quickly identify the cause of abnormality and response to the situation is a vital work for the safe operation of the plant. In the EEMUA 191 Guide pressed by Engineering Equipment and Materials Users Association (EEMUA), general principles of design and evaluation of plant alarm systems are proposed. Based on this guide, we propose a systematic design approach of the plant alarm system. In the design stage, based on cause-effect analysis, a set of alarm source signals are selected. For alarm system rationalization, we prepare countermeasures against repeating alarm suppression. As for the evaluation of the designed alarm system, we refer to the criteria provided by EEMUA 191 Guide and other indexes such as the malfunction identification time of a human operator model as well. The design methods are applied to the alarm system of a boiler plant simulator as a case study. Evaluation results show the usefulness of the proposed approach.
