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
