The invention relates to a heavy haul railway wagon network marshalling method and a wireless ad hoc network system, and the method comprises the following steps: a plurality of wagons in the same physical marshalling enter a marshalling station track one by one, the station track line number of the station track is obtained, and a wireless communication channel is selected based on the station track line number; recording time information for acquiring the station track line number, and generating marshalling information based on the time information and the vehicle identifier ID of the truck; a plurality of trucks in the same physical marshalling carry out marshalling information exchange and marshalling information comparison in the same wireless communication channel, the marshalling position of each truck is determined, and a marshalling first truck generates a marshalling list based on a marshalling information comparison result. According to the method, the railway wagons on different marshalling station tracks are supported to be subjected to wireless network marshalling at the same time, same-frequency interference is avoided, the accuracy of wireless network marshalling is improved, a wireless ad hoc network is constructed in the marshalling process, a network base station along a railway does not need to be used, and railway private network resources are not occupied.

本发明涉及一种重载铁路货车网络编组方法及无线自组网系统，包括以下步骤：同一物理编组中的多个货车车辆逐一进入编组股道，获取该股道的股道线路编号，基于股道线路编号选择无线通信信道；记录获取股道线路编号的时刻信息，基于时刻信息与货车车辆的车辆标识ID生成编组信息；同一物理编组中的多个货车车辆在同一无线通信信道内进行编组信息交换并进行编组信息对比，确定各车辆的编组位置，编组首车基于编组信息对比的结果生成编组列表。本发明支持不同编组股道上的铁路货车同时进行无线网络编组，避免了产生同频干扰，提高无线网络编组的准确性，编组过程中构建无线自组网络，无需使用铁路沿线的网络基站，不占用铁路专网资源。
