| Abstract: | 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. |
