摘要：
针对vxi-1394控制器不支持共享本地计算机内存,不能高效进行连续数据采集这一问题,以vxi-1394控制器和vxi-mio-64xe-10数据采集模块构建的系统为例,在增加vxi控制系统内存硬件的基础上,分析了连续数据采集的三种模式,并采用双缓存技术,解决了虚拟仪器技术中连续数据的采集和存储问题。研究成果成功用于飞机进气道控制系统处理机动态测试设备中。

abstract: according to the fact that the local shared memory isn't supported by the vxi-1394 controller, which make the consecutive data acquisition be not effective for the system. taking the system based on vxi-1394 and vxi-mio-64xe-10 for example, three kinds of models for consecutive data acquisition were analyzed on basis of enhanced memory of vxi controllers. consecutive data acquisition and storage for virtual instrument was also carried out with the double buffer technique. the research results has been successful used in dynamic testing equipment for aircraft airscoop control system.
