| Abstract: | To improve the performance of engine emissions, the data acquisition system is designed based on queued state machine in software of LabVIEW. The system can achieve the functions of multi-channel real-time data acquisition, dis play and data store in the form of TDMS files. When processing data,TDMS files can be operated by calling relative func tions in the DLL files with Matlab. The results indicate that the system has high reliability, fast response, high efficiency during processing data. |
