摘　　要：为了方便地研究等离子体激发过程的优化及控制,设计了等离子体激励源的液晶显示系统。结合图形液晶显示模块G121C与C8051F020,实现了系统相应的硬件电路和控制程序。结合G121C中集成液晶控制器SED1335的丰富指令系统,可以实现图文混合显示,并进行波形的平滑滚动。从而实现等离子体激励频率、功率、反射系数和驻波比等的动态显示,为等离子体激发的研究以及应用研究建立了良好的人机界面。To study the optimizing and controlling of plasma exciting expediently,we design a liquid crystal display system of the plasma exciting source. Combining the liquid crystal model G121C and C8051F020, we realize the corresponding hardware circuit and controlling program. With the G121C＇s integrated liquid crystal controller SED1335, the system can display Combing texgraphics and can scroll the wave smoothly. Accordingly we achieve the display of voltage, temperature, reflectance and standing wave ratio of the plasma exciting source dynamically. With this system, we establish a favorable humanmachine interface for the study of the plasma exciting and the application.
