1. An operation diagram-based method for automatically changing a route to turn back in case of interruption, wherein the method comprises: obtaining an alternative turn-back point according to a position of a fault point and information of a line turn-back station, calculating a corresponding turn-back plan of the alternative turn-back point according to an operation diagram of a current day, and finally automatically changing an online train route according to a new turn-back plan, so as to realize automatic turn-back of a train after route adjustment in case of interruption,
wherein the method comprises following steps:
step S1) inputting fault position information, original operation diagram plan information and line station type diagram information;
step S2) finding an affected original planned route, the alternative turn-back point and an alternative route according to information input in step S1;
step S3) obtaining a departure interval of the alternative route obtained in step S2 according to a planned interval of the original planned route;
step S4) calculating a turn-back time of the alternative route according to the departure interval of the alternative route obtained in step S3;
step S5) making a matched new turn-back plan for an online train according to original operation diagram planned time and a position of the online train input in step S1;
step S6) updating a running path of the online train according to the new turn-back plan obtained in step S5;
step S7) conducting turn-back number changing according to the turn-back plan obtained in step S5 after the online train with route changed in step S6 reaches the alternative turn-back point; and
step S8) after the online train arrives at another terminal of the alternative route, if the another terminal is a non-alternative turn-back point, turning back according to a planned train number obtained after number changing in step S7.
