摘要：安全級控制顯示裝置是核電廠(chǎng)操作員與數字化核安全級DCS系統進(jìn)行交互的人機接口。其能夠以圖形和文字的方式向用戶(hù)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(hù)可通過(guò)安全顯示設備對現場(chǎng)設備進(jìn)行操作。安全控制顯示設備采用觸摸屏實(shí)現控制功能、監視功能，觸摸屏坐標的正確性會(huì )成為關(guān)鍵指標。電阻觸摸屏長(cháng)期運行可能出現坐標偏移，本文對觸摸屏校準功能進(jìn)行了需求分析，提出了一種“四點(diǎn)校準、四點(diǎn)確認”的觸摸屏校準方案，對方案進(jìn)行了安全分析與設計，對校準步驟進(jìn)行了闡述，對實(shí)現了此功能的產(chǎn)品進(jìn)行了驗證與系統測試。實(shí)現觸摸屏校準功能的SCID已經(jīng)在首臺套陽(yáng)江56號機組進(jìn)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
