2) the method comprises the following steps that the No. 1 vehicle of a first section group sends wireless data to the No. 2 vehicle, the No. 3 vehicle and the No. 4 vehicle, wherein the No. 3 vehicle and the No. 4 vehicle transmit network data to the No. 5 vehicle, the No. 6 vehicle, the No. 7 vehicle and the No. 8 vehicle in a second section group; by analogy, the No. 7 vehicle and the No. 8 vehicle transmit the network data to the No. 9 vehicle, the No. 10 vehicle, the No. 11 vehicle and the No. 12 vehicle in the third group;
3) the second section of group preferentially executes the instruction sent by the vehicle No. 3 and ignores the same instruction sent by the vehicle No. 4, and similarly, the third section of group preferentially executes the instruction sent by the vehicle No. 7 and ignores the same instruction sent by the vehicle No. 8.
