中文摘要：

为了处理EAST核聚变装置低杂波相位控制子系统中存在的两种不同的相位数据,针对它们的各自特点,子系统采用了不同的传输和显示方法。尤其是对于数据量较大的全部相位数据,子系统利用LZO算法将其压缩后以TCP方式发送。控制室QNX计算机使用PtTrend控件和PtRaw控件来进行数据的显示处理,速度快且具有良好的可靠性。测试结果表明,子系统的设计满足实验要求,并对其它基于QNX实时操作系统的数据处理有一定的参考意义。

英文摘要：

Two kinds of phase data exist in the LHCD phase control subsystem of EAST tokamak.So the different methods of transmission and display are used to process the respective phase data.Especially,for all the phase data,the LZO algorithm is adopted to compress the data and then the TCP protocol to send it.The PtTrend widget and PtRaw widget are used to display the phase data,which is quick and reliable.Besides,these methods can serve as a reference to deal with other data based on the QNX realtime operating system（RTOS）.
