Application of FIR filter in ground signal detection of diesel locomotives
During the operation of diesel locomotives,aging of equipment or cables,vibration,and friction can cause grounding of the vehicle's main circuit or equipment output,endangering the running safety.The vehicle grounding signal interfered from control pulses and common mode signals can cause serious distortion and lead to grounding misjudgment.Therefore,the window function FIR(Finite Impulse Respond)filter is introduced to process the original grounding signal.We built a grounding simulation model using Matlab to conduct simulation research and design on the filtering method.Experimental verification shows that the filter can quickly and accurately determine the grounding situation of locomotives,providing reliable guarantees for train operation safety.
