Signal machine kilometer post proofreading method and device for train operation and medium

The invention relates to the technical field of LKJ distance proofreading, in particular to an annunciator kilometer post proofreading method and device for train operation and a medium, and the method comprises the following steps: S1, installing a signal simulation device in an adjustment and defense system; s2, acquiring the position of an on-board signal machine and the real-time position of a train S3, calculating the distance between the train and the annunciator; s4, calculating the time point when the first wheel pair of the train passes through the signal machine; s5, the adjusting and defending system sends an insulation joint simulation signal to the vehicle-mounted LKJ equipment through the signal simulation equipment; and S6, the vehicle-mounted LKJ device proofs the signal machine kilometer post in the LKJ basic data through the insulation joint signal. Compared with the existing LKJ distance automatic proofreading technology, the method has the advantages that the train is accurately positioned
