Design of locomotive insulation joint detection device based on track circuit

In the current LKJ-2000 train operation monitoring system, the insulation section detection device is placed in the ground information processing module. the insulation section detection device is integrated into the ground information processing module. This module receives track signals, detects and processes insulation section signals, and manages upstream and downstream information from the track circuit system. Consequently, this increases the load on the primary processor, elevates energy consumption, and compromises security. In this paper, we studied the current insulation joint detection device, found the optimized structure and module, and optimized and improved the software and hardware of the detection device. Finally, through the experimental data on the experimental platform, we can see that the maximum delay is about 20ms, which is in line with the practical engineering application standards.
