Application of Ecological Interface Design Theory in Human-machine Interface Design of Nuclear Power Station

With the application of DCS technology in nuclear power station, the digital control interface that takes computer as centralization was used extensively in nuclear power station. The effect of the application of ecological interface design (EID) theory in human-machine interface (HMI) in nuclear power station based on the actual HMI examples in nuclear power station was analyzed. The analysis shows that EID has important application value in HMI design of nuclear power station, and the application of EID theory in nuclear power station will better organize the display information and improve operator’s ability to solve problems when encountering unanticipated events.
