In practice, the automatic passing neutral section signal processor identifies signals sent by sensors arranged on the rails to judge whether the locomotive reaches a passing neutral section point. Therefore, when the direction of the locomotive head of the locomotive is adjusted, a signal needs to be sent to the automatic passing neutral section signal processor, so that the automatic passing neutral section signal processor acquires the advancing direction of the locomotive, and the judgment on the sequence of the received signals is adjusted. For example, as shown in fig. 4, when the locomotive moves from left to right, a forenotice ground positioning signal is sent to the automatic passing neutral section signal processor at a point G1, a forced ground positioning signal is sent to the automatic passing neutral section signal processor at a point G2, and a closing ground positioning signal is sent to the automatic passing neutral section signal processor at a point G3.
