摘要：安全級控制顯示裝置是核電廠操作員與數字化核安全級DCS系統進行交互的人機接口。其能夠以圖形和文字的方式向用戶顯示核反應堆運行狀況和DCS系統本身設備的運行狀況，用戶可通過安全顯示設備對現場設備進行操作。安全控制顯示設備采用觸摸屏實現控制功能、監視功能，觸摸屏坐標的正確性會成為關鍵指標。電阻觸摸屏長期運行可能出現坐標偏移，本文對觸摸屏校準功能進行了需求分析，提出了一種“四點校準、四點確認”的觸摸屏校準方案，對方案進行了安全分析與設計，對校準步驟進行了闡述，對實現了此功能的產品進行了驗證與系統測試。實現觸摸屏校準功能的SCID已經在首臺套陽江56號機組進行了成功應用。

Abstract: The safety level control and display device is a man-machine interface for nuclear power plant operator to interact with digitalnuclear safety level DCS system. It can display the operation statusof nuclear reactor and the operation status of the DCS system's ownequipment to the user in the form of graphics and text. Users canoperate the field equipment through the safety display equipment.Safety control and display equipment uses touch screen to realizecontrol function and monitoring function. The accuracy of the touchscreen coordinates will become a key indicator. Long-term operation of the resistive touch screen may cause coordinate shifts. In this paper, theneeds of the touch screen calibration function are analyzed, and a "fourpoint calibration, four-point confirmation" touch screen calibration scheme is proposed. The scheme is safely analyzed and designed.The calibration steps it elaborated and implemented verification and system testing on the products that realized this function. SCID, which realizes the touch screen calibration function, has been successfully applied in the first set of Yangjiang 56 Unit.

Key words: Firmsys, SCID; Touch screen calibration; Application
