基于μC/OS-Ⅱ与LabVIEW的井下低压选择性漏电保护系统研究
Research on Selective Leakage Protective System of Coal Mine L-V Network Based on μC/OS-Ⅱ and LabVIEW
Aiming at the problems exiting in protection system of low-voltage distribution network in coalmine,a new leakage protection system based on μC/OS-II and LabVIEW was put forward.Upon μC/OS-II and ARM,a centralized control method with several leakage judge algorithms were adopted by the leakage protection device.The monitoring software developed by LabVIEW showed the status of the power network,send out alarm signals and recorded the fault when a leakage happened.Tests demonstrated that the system with friendly interface responded fast,reliably and selectivity,which improved the stability of the power network.
