Abstract

The invention discloses a method and system for associating positioning information with a train based on multi-source data, and the method comprises the steps: collecting train operation data of multiple data sources, and carrying out the preprocessing of the train operation data; carrying out train number clustering on the train operation data to obtain train walking data, and carrying out train number crossing on the train walking data to obtain a train walking path; carrying out positioning integrity monitoring on the running path of the train to obtain integrity data, and correcting the integrity data according to the real-time data to obtain monitoring correction data; calculating train positioning according to the monitoring correction data, and constructing a positioning information and train association model according to the train positioning; and optimizing the positioning information and train association model according to the positioning error, inputting to-be-associated data into the positioning information and train association model, and outputting an association result. The method can improve the correlation precision of the positioning information and the train, has good interpretability, and can be directly applied to a train information positioning system.
