5) the locomotive control unit receives a shunting instruction signal sent by the shunting leader transfer control unit for automatic identification, color lamp lighting display and voice prompt, and sends shunting voice prompt to the shunting leader transfer control unit, the connection/brake operator operation control unit and the network leader control unit;
6) after the shunting chief transfer control unit receives the response command sent by the locomotive control unit, the shunting chief transfer control unit synchronously sends the response command of successful data transfer sending to the connection/brake operator operation control unit;
7) the connection/brake operator operation control unit takes the received response command as a basis for transferring and transmitting the shunting command signal successfully, and simultaneously broadcasts corresponding prompt voice through a loudspeaker;

The shunting instruction voice signal weak field reinforcement processing flow is as follows:
1) the operator of the connecting/brake operator operation control unit is positioned at the front part of the propelling train, confirms that the distance is correctly observed after the operator stays at the parking place, and calls and displays distance signals of ten cars, five cars and three cars in time;
2) the operator of the connecting/braking operator operation control unit connects/brakes the parking, deceleration, ten-vehicle, five-vehicle, three-vehicle and approach connection and hanging signals called by the operator, and the shunting conversation words can be sent out in a shunting instruction voice signal mode by operating any three keys on the connecting/braking operator operation control unit;

after the locomotive control unit sends a response command, the locomotive control unit synchronously carries out automatic identification, color lamp lighting display and voice prompt on a shunting instruction signal sent by the shunting leader transit control unit in a weak field reinforced transmission mode, and sends shunting voice back to the shunting leader transit control unit, the connection/brake operator operation control unit and the network district leader control unit to control the normal work of the locomotive.
