| Abstract: | Superconducting magnetic energy storage （SMES） is working in hypothermia. It needs to monitor multi- channel voltage, temperature and magnetic field intensity. Taking the advantages of LabVIEW graphical programming, a SMES monitoring system is developed based on LabVIEW, which is able to achieve multi-channel data acquisition, processing, display and save. For nonstandard temperature probe signal conversion difficulties, use the formula Node in LabVIEW,The temperature error is controlled within 0.3 K. Multi-channel signal comparison is achieved in waveform graph,which is easy to know the temperature of each parts of the SMES magnet. It is conducive to the operation of SMES. Saving the data to common Excel files is good for analyzing in the future. Besides, the system is very simple, to facilitate the use of researchers. |
