The invention belongs to the technical field of robots, and provides a robot congestion prevention method under a warehouse sorting system, and the method comprises the steps: obtaining a maximum flow node in a real-time map according to real-time map data; determining the roadway capacity characteristic of each roadway through the maximum flow node in the real-time map, and updating the real-time roadway flow of the roadway capacity characteristic at the same time; obtaining a shortest node path meeting an initial roadway capacity constraint based on the real-time roadway flow; and according to the shortest node path, robot congestion under the warehouse sorting system is prevented. The method disclosed by the invention is high in collaboration and good in adaptability, the congestion probability of the robots in the whole warehouse area is remarkably reduced, and the sorting efficiency and the carrying efficiency of the warehouse sorting system are improved. 本发明属于机器人技术领域，本发明提供一种仓库拣选系统下的机器人拥堵预防方法，包括：根据实时地图数据
