摘　　要：EAST超导托克马克装置是一种利用磁场来约束等离子体的受控热核聚变物理实验装置;炮号显示模块是EAST装置总控系统的组成部分之一,用来为给子系统提供当前的炮号及放电长度等信息,是以AVR系列单片机atm ega128为核心,基于NUT/OS嵌入式实时操作系统完成了该显示模块的基本设计,给出了该模块的硬件和嵌入式软件的设计方案与实现方法;该模块已成功投入到2006年12月EAST超导托卡马克核聚变装置的放电试验中,实验结果表明,该模块运行稳定可靠,符合预定的设计目标。EAST Superconductive Tokamak is one kind of physical experiment installation which restrains the plasma using the magnetic field to control thermonuclear fusion . The ShotNo display module is a part of the central control system in the EAST Superconductive Tokamak. It is used to provide the ShotNo, discharge length and other information to subsystems. This job is centering on atmega128, based on the embedded RTOS NUT/OS to complete the basic design of the display module. This paper gives designable scheme and method. This module has been successfully used in the experiment of the EAST Superconductive Tokamak fusion equipment on December 2006. The application shows that this module runs stably and accords with the scheduled design goal.
