The invention discloses a method for improving the train length calculation precision of a shunting protection system. The method comprises the following steps that the train length L of a train is divided into the train front length Lf and the train rear length Lb with the position of a GPS antenna on a locomotive as a demarcation point; the station track number of a train is obtained according to the locomotive position, and the positions of all insulation joints on different sections of the station track are obtained; the locomotive end calculates the data of the front length of the locomotive once when the head end of the front length of the locomotive passes through one insulating joint, and the locomotive end calculates the data of the rear length of the locomotive once when the tail end of the rear length of the locomotive passes through one insulating joint; comparing all the calculated vehicle front length data, and taking the maximum value in all the vehicle front length data as the value of the vehicle front length Lf; comparing all the calculated vehicle rear length data, and taking the minimum value in all the vehicle rear length data as the value of the vehicle rear length Lb; the length value of the train is obtained by adding the length Lf in front of the train and the length Lb behind the train, and the length of the train set can be calculated more accurately.

    本发明公开一种提高调车防护系统车长计算精度的方法,包括如下步骤:以GPS天线在机车上的位置为分界点将列车的车长L分为车前长Lf和车后长Lb;根据机车位置获取列车所在的股道号,获取股道上不同区段上各绝缘节的位置;车前长的首端每过一个绝缘节时,机车端均计算一次车前长数据,车后长的尾端每过一个绝缘节时,机车端均计算一次车后长数据;将计算出的所有车前长数据进行比对,取所有车前长数据中的最大值作为车前长Lf的值;将计算出的所有车后长数据进行比对,取所有车后长数据中的最小值作为车后长Lb的值;将车前长Lf与车后长Lb相加,获取列车的车长值,能更准确地推算出机车车列的长度。
