AI Technical Summary
In the shunting protection system, there is a large deviation in the calculation of car length, which affects the control accuracy of shunting operations. This is mainly due to the communication delay of interlocking signals and the acquisition delay of track circuits.
A GPS antenna is installed on the locomotive. The train length is divided into front length and rear length using GPS positioning. The train interacts with the interlocking communication server through the LKJ interface to correct communication delay. The GPS position difference when the position of the insulating joint changes is recorded. The optimal front length and rear length are calculated. The maximum and minimum values are added together to eliminate the effect of time delay.
It improves the accuracy of car length calculation in the shunting protection system, enhances the safety and control precision of shunting operations, and strengthens the system's intelligence level.
