Abstract

Abstract A good human-computer interface can improve the efficiency of operators in the main control room of a nuclear power plant (NPP) and reduce operational errors. It has been shown that ecological interface design (EID) can effectively reduce the cognitive load of users, improve the level of situation awareness, and help users to make decisions quickly and effectively. In this paper, we analyzed the feedwater deaeration system (ADG) of nuclear power plants, constructed the work domain analysis according to the abstraction hierarchy theory. The factors that affect the balance of the system are clarified, and the ecological interface is designed based on it, so that it can present the system status and present the future development trend more intuitively, and support the operator to predict the system situation. In this study, 10 volunteers with relevant knowledge background were selected for operational experiments, with subjective evaluation based on SART scale and grey theory, which verified that EID interface has significant advantages over the original interface in supporting both operator response time and accuracy.

核电厂给水系统生态界面设计与评价

摘要良好的人机界面可以提高核电站主控室操作人员的工作效率，减少操作失误。研究表明，生态界面设计(EID)可以有效减少用户的认知负荷，提高用户的态势感知水平，帮助用户快速有效地做出决策。本文对核电厂给水除氧系统进行了分析，根据抽象层次理论建立了工作域分析。明确影响系统平衡的因素，并以此为基础设计生态界面，使其能够更直观地呈现系统状态和呈现未来发展趋势，支持操作者对系统状况进行预测。本研究选取了10名具有相关知识背景的志愿者进行操作实验，并基于SART尺度和灰色理论进行主观评价，验证了EID接口在支持操作员响应时间和准确性方面都比原始接口具有显著优势。
