Abstract: Distributed dynamic data acquisition system (DAS) is used to evaluate power quality and robustness of ship power system. In this paper, the hardware configuration based on PXI platform and the program frame based on TCP/IP communication are described. Functions programed with LabVIEW environment as DAQ tasks setup, data transmitting and receiving, data processing, waveform analysis, history data query and exportation are mainly studied. Site test shows the program frame above is applicable to distributed multi-channels and high-rate dynamic data acquisition and has advantages in system stability and flexible task management.
