Referring to fig. 2, fig. 2 is a flowchart illustrating steps of a shunting data processing method provided in the present application, the shunting data processing method including:
s101: acquiring the distance between the locomotive head and a target signal machine, wherein the target signal machine is the signal machine in front of the locomotive in operation;
specifically, the locomotive head in this embodiment specifically refers to a locomotive head at an occupied end of a cab, and the target signal is specifically a signal in front of the locomotive running and to be approached by the locomotive. The positions of the locomotive and target signals and the direction of the rail vehicle can be seen with reference to fig. 3. The automatic driving device ATO can acquire the distance between the locomotive head and the target signal machine according to a certain acquisition cycle, and can also acquire the distance between the locomotive head and the target signal machine according to a certain acquisition cycle after receiving the acquisition command so as to reduce the data processing amount of the ATO.
It can be understood that, in the prior art, once the locomotive head passes over the target signal, the shunting data behind the target signal will disappear, and therefore, the purpose of obtaining the distance between the locomotive head and the target signal in this step is to determine whether there is shunting data about to disappear, so as to perform subsequent buffering processing operations.
