摘　　要：应用于核电厂保护系统中的图形显示单元,属于安全级设备。该设备需要能够动态显示保护系统相关数据,并为操纵员提供手动控制保护系统相关功能的接口。该设备的研制过程中需遵循安全级设备的相关法律、法规或导则。简化硬件、软件设计可有效提高图形显示单元的可靠性并减小软件V&V工作复杂度。本文将针对作为图形显示单元核心的图形显示控制器设计,提出一种新的设计方法,使得该控制器实现过程得到简化,性能得到提升。The graphic display unit applied to the protective system in nuclear power is defined as a safety level instrument.This instrument should display the dynamic data which got from protective system,and support an interface for the operator to control related function of the protective system.The process of developing this instrument should obey the law or rules related to safety device.Simplification of the hardware or software design can enhance the reliability of graphic display unit,and reduce the V&V complexity of software.This methodology focused on the graphic display controller of graphic display unit design will put forward a new method that can simplify the design of graphic controller and enhance its performance.
