Background
The shunting operation is an important component in the railway transportation process, the shunting operation of a railway station is mainly carried out in a non-centralized shunting operation area, the shunting operation command of the non-centralized area is the key of the shunting operation of the non-centralized area, and the shunting operation command of the non-centralized area is directly related to the smooth operation of the shunting operation work of the non-centralized area. For the operation in the non-centralized area, the general dispatching command is a station dispatcher or a station attendant, and the current situation and the existing problems of most of the non-centralized areas are as follows:
