基于虚拟仪器HS801的杂散电流监测

The Stray Current Monitoring Based on HS801 Virtual Instrument

杂散电流监测对城市轨道交通的杂散电流防护具有重要意义。虚拟仪器HS801具有良好的性能,能够满足杂散电流监测的需求。文章给出了基于HS801的杂散电流分区监测方案,介绍了利用动态链接库对虚拟仪器HS801进行二次开发的方法。

The stray current monitoring is very important to prevent from stray current of Urban Mass Transit. The HS801 virtual instrument has good performances and can satisfy for the demand of monitoring of stray current. The monitoring scheme of stray current in subarea based on HS801 was given in the paper. The method of the secondary development of HS801 with DLLs was introduced.
