[0031] like Figure 1 、 Figure 3 、 Figure 5 and Figure 6As shown, the external locator 2 includes a housing 21, which houses a battery, a Beidou positioning module, a third communication module, a charging circuit, and a charging connector.

The ground server is connected to a ground differential base station via a VPN, which is in turn connected to the Beidou positioning system. This allows for comprehensive calculations to obtain the locomotive's precise positioning information and upload it to the ground server. The ground server then integrates the locomotive positioning information with the station map, compares it, and calculates it to obtain comprehensive protection information. This information is then output to the intelligent display terminal 1, which displays the station map and the locomotive's precise location information. In this way, when performing locomotive shunting operations, drivers can effectively avoid accidents such as squeezing switches, crossing station boundaries, damaging approaches, and collisions, effectively reducing shunting risks.

[0033] In summary, by using this utility model, drivers can effectively avoid accidents such as squeezing switches, crossing station boundaries, damaging routes, and collisions when performing locomotive shunting operations, effectively reducing the risk of shunting.
