| 摘 要： | 为满足核聚变装置EAST极向场电源控制系统的实时性要求,设计了基于QNX的实时数据采集系统。与一般的软件触发数据采集方式相比,本文采用的利用QNX系统时钟实现的数据实时采集方式显著减少了对CPU资源的占用。实践表明这种数据采集模式更适用于实时控制应用场合,是可靠而高效的。

| Abstract: | The poloidal field power supply control system of the nuclear fusion device-EAST requires high real-time performance., so we designed this real-time data acquisition system based on QNX. Compared with normal software-trigger data acquisition mode, the real-time data acquisition mode described in this paper reduces system spending observably. The practice shows that the real-time data acquisition system based on QNX has high efficiency and reliability. |
