摘　　要：为了解决云粒子测量系统中并行数据采集通道之间的信息交互问题,采用LabVIEW中库函数节点、消息队列和状态机相结合的方法,实现了多路不同速率数据的并行采集,试验验证了该并行数据采集方法的可行性.研究结果表明:基于LabVIEW进行并行数据采集,不但快速、简单,并且能够有效提高数据采集效率,方便进行系统扩展.该方法对多路并行数据采集系统设计具有一定的参考价值。In order to solve the problem associated with information interaction among parallel data acquisition channels in cloud particles measurement system,an approach for multichannel parallel data acquisition in different rates is proposed and implemented by applying the library function nodes,the message queue and state machine in LabVIEW in this study.Experiments demonstrate that the proposed approach is feasible.The study results show that the parallel data acquisition based on LabVIEW is not only fast,simple,but also efficient in data acquisition,and convenient for system extension.The proposed approach is useful for multichannel parallel data acquisition system design.
