基于Qt4的LHCD相位控制软件的设计

摘要

The software of Lower Hybrid Current Drive ( LHCD) phase control is an important part of realizing the LHCD phase control, which is applied to raw data acquisition and processing from the hardware circuit of LHCD system,and it can drive the phase shifter by phase feedback calculation to reach the purpose of changing the phase difference between the adjacent main-waveguides of the antenna and controlling the spectrum distribution. This software uses C++application framework Qt as the development tool and a lot of software technology such as signals and slots mechanism,multithreading,QTimer and Qt drawing tool is applied to it. The software can be satisfied for the most of requirements of the LHCD system,and will be tested in the physics experiments.%低杂波相位控制软件是实现低杂波相位自动控制的重要组成部分,它可以完成对低杂波相位检测电路的输出数据进行读取和处理,并通过相位反馈来驱动移相器以达到调节低杂波天线上主波导之间的相位差和控制波谱分布的目的。基于Qt的LHCD相位控制软件使用C++应用程序框架Qt作为开发工具,利用信号与槽机制,多线程机制,Qt定时器以及Qt绘图工具等软件技术进行编写。相位控制软件在模拟实验中已经实现了其主要功能,期望在实际应用中得到进一步验证。
