judging whether the distance between the second metering shaft and the first metering shaft is not smaller than the maximum value;
if the judgment results are yes, determining the layout position of the second axle counting, and laying the second axle counting;
the preset formula specifically comprises the following steps:
L1=M1+M2+M3+M3*M1
wherein L1 is the shortest distance between the front end of the train head and the second axle, M1 is the mounting error of the accurate parking transponder, M2 is the solid envelope of the train, and M3 is the maximum retrogressive distance.
