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 of information exchange between parallel data acquisition channels in cloud particle measurement system, the parallel acquisition of multiple data with different data rates is realized by using the library function nodes, message queue and state machine in LabVIEW. The parallel data acquisition method is feasible.The results show that the parallel data acquisition based on LabVIEW is not only fast and simple but also can effectively improve the data acquisition efficiency and facilitate the system expansion.This method has some advantages for the design of multiple parallel data acquisition system Reference value.
