摘　　要：高压气体注入是目前托卡马克装置缓解破裂的主要手段,一种靠涡流驱动的适用于等离子体破裂防护的快速充气阀已经在中科院等离子体物理研究所研制成功,为了使快阀实现远程可控、可监视,并且实时记录充电电压及工作气压的变化情况;我们以研华工控机及NI-6299数据采集卡为硬件技术,lavVIEW8.6为编程环境的控制及采集系统;该系统充分利用labVIEW图形化编程语言直观特性进行控制及数据采集;该快阀远程监控及数据采集系统的建立,很好地满足了快阀系统的控制要求;这一系统的可靠性已经在台面实验中得到了验证,在试验中该系统可以实时显示快阀系统的主要状态,并可实现对电压、气压进行远程调节并记录试验数据;其性能将2012年春季EAST等离子体放电试验中继续进行检验。Disruption is often happened during Tokamak discharge, which is harmful to the device. By injection high pressure noble gas into the device before disruption happen is a promising method. At present a fast valve for disruption mitigation has been developed success fully, for realize remote control , visible and can he convenient calculation the amount of injection gas , a set of remote control and data ac quisition system based on LabVIEW for fast valve was designed , the reliability of the system has been verified in the table experiments and which will be used on 2012 EAST experiments.
