Abstract: At early stage of the establishment of the railway face retrieval platform, the management of business address was completed by the manual modification of Apollo configuration center. Its operation process was complicated and maintenance efficiency was low. The intelligent traffic navigation could effectively solve the problem of balanced dispatching with the business address. This paper described the functional composition and technical architecture of the portrait retrieval platform, pointed out the problems of the existing platform such as low operating efficiency and unbalanced traffic dispatching. Through configuration transformation, the service routing address pool was formed, and according to the estimated daily passenger flow of each station, the concept of station grade was put forward and the station weight was formed, intelligent traffic dispatching strategy was designed based on weight. The implementation of intelligent traffic dispatching simplified the work of operation and maintenance, made the traffic dispatching of portrait retrieval platform more balance.
