摘要：安全级控制显示装置是核电厂操作员与数字化核安全级DCS系统进行交互的人机接口。其能够以图形和文字的方式向用户显示核反应堆运行状况和DCS系统本身设备的运行状况，用户可通过安全显示设备对现场设备进行操作。安全控制显示设备采用触摸屏实现控制功能、监视功能，触摸屏坐标的正确性会成为关键指标。电阻触摸屏长期运行可能出现坐标偏移，本文对触摸屏校准功能进行了需求分析，提出了一种“四点校准、四点确认”的触摸屏校准方案，对方案进行了安全分析与设计，对校准步骤进行了阐述，对实现了此功能的产品进行了验证与系统测试。实现触摸屏校准功能的SCID已经在首台套阳江56号机组进行了成功应用。

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.
