Abstract

A method and device of multi-train operation trend deduction. Temporary speed limit information, scheduling information, line information and train status information are obtained; the coupling relationship between the trains traction calculation and the area of space-time scope which is under temporary speed limit are analyzed, and the time saving driving strategy of the first train within the time domain is calculated; according to the running position and speed of the front train, a multi-train operation tracking model under different block systems is established; according to the temporary speed limit information, the driving strategy of following tracking train is deduced, and the operation of the multi-train is calculated; the operation trend of multi-train to the driving scheduling platform is sent.
