the data transfer planning module is used for judging whether the receiving and transporting route of the communication transfer vehicle is shorter than the receiving and transporting route of the associated weak communication vehicle: if so, after the communication transit vehicle reaches the collection and transportation terminal position, the communication transit vehicle continues to travel to the collection and transportation terminal position of the associated weak communication vehicle to receive the garbage collection and transportation data; otherwise, after the vehicle reaches the collection and transportation end point, the vehicle continues to drive to the collection and transportation end point of the communication transfer vehicle related to the vehicle to send the garbage collection and transportation data.
