Application

 

Track circuit is a crucial signal equipment to determine the location of a train, which often appears troubles because of its complex working environments. Through data collection from the track circuit, digitalized and intelligent real time trace circuit test panel achieves tracking, recording and alarming of track circuit’s working status and accordingly providing supporting data for fault processing.

 

Adopting modularized and digitalized component structure, PS25-I Digitalized and Intelligent Real Time Trace Circuit Test Panel (hereinafter referred to as “Test Panel”) is specially designed for 25HZ phase detecting track circuit, which is able to synchronously collect and display receiver’s information of 48/26 track circuit section in real time and can be networked through CAN.

Functions

 

1) To digitally and intelligently collect 25HZ alternating voltage, phase angle and 50HZ from receiver of 25HZ track circuit. (manual operation free, 48/26 data is updated on second basis.

 

2) 25HZ signal monitoring range: Voltage电压0~40V; Phase angle 0~360 degrees;

 

3) 25HZ signal monitoring range: Voltage电压0~40V

 

4) Monitoring Accuracy: Voltage ±1%; Phase angle ±1%;

 

5) Alarm: To alarm and record anomalous changes in order to provide supporting evidences for determining track circuit problems through configuring 25HZ receiving voltage of track section and phase angle’s upper and lower bounds of alarm thresholds; to alarm and record the values beyond the limit in order to provide solid evidences for track circuit problems analysis through configuring 50HZ interference voltage of track section’s upper and lower bounds of alarm thresholds.

 

6) Record: The device will put all the targeted track sections’ information on storage device in real time when the button is clicked.
