基于Labview的ICRH发射机监控系统的开发

Development of monitored control system of ICRH based on Labview

本文主要介绍HT-7离子回旋共振加热系统,基于可视化开发软件Labview设计的发射机系统的电子管电参数计算机监控系统的开发。此系统在检测的过程中,连续采集四极管相应的电参数,如果相应管件不在额定的条件下工作时,则发出声音及视觉警报,向现场工作人员提出警示,并加以保存。整个系统功能较为完善,尤其在长时间使用发射机时,对有效监控系统及现场维护提供了完善的监测手段;同时,通过采用事件驱动、通道选择算法、频谱分析的计算机技术和数学分析技术,完整记录了发射机系统的真实工作状况。特别是通道选择算法,则解决了在采集过程中,无法随时更改在线的通道数的问题,在实验阶段取得了良好的效果。

In this paper, the monitor and control unit of Ion Cyclotron Range of Frequency heating （ICRH） system on HT-7 is mainly presented. The whole system is based on Labview system. Because of the tetrode working in severe condition, such as high voltage over to 13,5kV, the whole system must be under control. This system acquires the corresponding electric parameter of the tetrode constantly during the process of measuring. If the corresponding component while out of the specified range, the system will give sound and vision alarm. By using event-driven, channel-selected algorithm and FFT, we could record and show the true working state of the transmitter system and corresponding analysis exactly. Moreover, the algorithm of the channel selection solves the problem which was unable to switch the channels online while data acquiring at any time.
