Abstract

The invention provides an insulation damage detection method, an insulation damage detection device and a computer program. The insulation damage detection method includes the following steps that: the head-to-tail ratio of pulse signals is acquired; whether the head-to-tail ratio is within a predetermined range is judged; and if the head-to-tail ratio exceeds the predetermined range, and insulation damage is determined. The insulation damage detection method, the insulation damage detection device and the computer program of the invention have the advantages of higher detection reliability and higher safety.

Description

technical field [0001] The invention belongs to the technical field of track detection, and in particular relates to an insulation damage detection method, device and computer program. Background technique [0002] At present, in the track circuit section of the railway station, the rails are divided into different track circuit sections by mechanical insulation joints. If the insulation joint is damaged, the signal of this section will leak to the adjacent section, which may cause errors in the track circuit signal. display, which poses a security risk. [0003] There are currently some existing technologies to solve security risks, such as figure 1 The shown safety protection system under the condition of insulation damage cumulative disconnection fault, 25Hz phase-sensitive track circuit, the adjacent sections are arranged in a polarity crossing manner to solve the safety protection after the insulation joint is damaged, that is, the insulation joints on both sides The ...
