Abstract
Through the research on the principle and relevant characteristics of asymmetric high-voltage pulse track circuits,combined with the action principle of track circuits and coding circuits,using the time sequence diagram and the records of on-site monitoring equipment,this paper emphatically analyzes the causes and timing of the code-missing problem of asymmetric high-voltage pulse track circuits on the main lines.The scheme and measures to solve the problem of locomotive code-missing when the two neighbouring sections use asymmetrical high-voltage pulse track circuit and 25 Hz phase-sensitive track circuit are proposed to provide guidance or reference for similar problems.关键词
