| Abstract: | A data acquisition system with a hardware structure based on virtual instrument and a software architecture based on LabVIEW platform,which used for vacuum signal monitoring,is introduced.The control computer and the acquisition instruments are connected together and communicate each other with USB 2.0 bus.Among multiple channels,the acquisition of signal data is synchronized with the high precision counter of the acquisition instrument.This system has been used in HL-2A Tokamak experiment,and can fully meet the requirement of the experiment. |
