Research on ZPW-2000A Track Circuit State Diagnosis Based on Set Pair Analysis

Abstract

For ZPW-2000A the traditional maintenance mode of uninsulated track circuit has some problems such as low efficiency and poor timeliness. This paper analyzes various index parameters that affect the running state of track circuit. Due to the influence of various random uncertain factors, such as the bad operation environment of track circuit equipment, the complex composition of equipment and the variety of fault causes, then the set pair analysis theory is introduced and the influence index is quantified by using the connection number. The degree of uncertainty is represented in mathematical form, and the expression of connection number between index and operation state is described systematically. The comprehensive and accurate state evaluation of track circuit is realized. Finally, an example is given to verify the effectiveness and feasibility of the proposed method.
