AI Technical Summary

Technical Problem

Existing technologies for detecting the integrity of railway track connections are sensitive to changes in the output current of the voltage source, which causes the measurement results to be affected by changes in the load resistance. Furthermore, line resistance correction is required, making it difficult to achieve high-precision and high-reliability monitoring.

Method used

The four-wire circuit, through the electrical safety intelligent diagnostic unit and the trackside acquisition unit, detects the track voltage and resistance, eliminates interference from contact resistance and lead resistance, and realizes automatic testing of track connection integrity.

Benefits of technology

It improves the accuracy and reliability of track connection status detection, reduces the consumption of manpower and material resources, and significantly improves the accuracy and frequency response range of the test.
