Abstract: A train control method, based on a combined coordinate system, includes: obtaining a target combined coordinate system corresponding to a planned train path, the target combined coordinate system comprising a plurality of basic coordinate systems with boundary logic sections, and each of the basic coordinate systems forming a physical link relationship with another basic coordinate system of the basic coordinate systems through the boundary logic sections; obtaining position information of a train located in the planned train path sent by the train, and determining preceding train information of a preceding train preceding to the train based on the position information and the physical link relationships between the basic coordinate systems; and performing a train control strategy on the train based on the preceding train information.

Abstract: A method for train positioning includes: periodically transmitting, by a balise transmission module (BTM), balise data to a vehicle on-board controller (VOBC) according to a rule; periodically receiving, by the VOBC, the balise data transmitted by the BTM, and periodically obtaining a data frame, the data frame comprising a current traveling time tn, a current traveling speed vn, and a current traveling distance sn of a train; and determining, by the VOBC based on the received balise data and the obtained data frame, a location of the train when the train passes a balise.
