摘要
超导磁储能系统(SMES)运行在低温环境中,需要监测多通道的电压、温度和磁场强度信号,利用LabVIEW图形化编程的优点,研制了一种基于LabVIEW的SMES监测系统,该系统能够实现多通道的数据采集、处理、显示和保存,针对非标准温度探头信号转换的难点,利用LabVIEW中的公式节点,将温度误差控制在0.3K以内,在波形图中实现了多通道信号的比较,便于掌握SMES磁体各部位的温度,这有利于监测SMES的运行状态,将数据保存为常用的Excel文件,有助于数据分析。系统操作简单,方便科研人员的使用。
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.
