Abstract: With the help of the characteristics of dense distribution of infrared axle temperature detection equipment, this paper set up the corresponding relation between infrared axis temperature detection equipment and train inspection workshop, through matching the passing data of infrared axle temperature detection equipment with the alarm vehicle data, it could be displayed to train inspection workshops to implement network monitoring. The paper analyzed the rules of pushing and selling alarm vehicles, developed the functions of network monitoring, backfilling, inquiry and statistics. The functions were tested in Fengtai Vehicle Depot of Beijing Railway Administration, and the network monitoring scheme was improved.
