Abstract

The invention relates to a train positioning device. The device comprises a carrier frequency information receiver and a train positioner. The invention further relates to a train positioning method. The method comprises the steps of: obtaining carrier frequency information; monitoring whether the obtained carrier frequency information is changed; obtaining a corresponding section joint point position according to the carrier frequency information when the carrier frequency information is changed, and obtaining a train distance measuring position when the carrier frequency information is changed; and positioning a train based on the section joint point position and the train distance measuring position. The positioning method reduces the intervention of manual operation to the greatest extent, so that the wrong operation is prevented to the greatest extent, and the influence of the operation timing on the positioning precision is prevented; and compared with the prior art, the positioning device and the positioning method have the advantages that the accuracy and the precision of obtained positioning results are greatly improved.

Description

Technical field [0001] The invention relates to the field of railway transportation, in particular to a train positioning device and method. Background technique [0002] Train positioning technology is one of the key core technologies of the train operation monitoring system (abbreviation: LKJ). When the train positioning error is large, it may lead to the failure of the functions closely related to the train position, such as the prevention of train advancing and the prevention of train overspeed in the train operation monitoring system. Therefore, the accuracy of train positioning is directly related to the safety of train operation. [0003] In the prior art, there are mainly the following methods for positioning trains: [0004] (1) At the departure station, after manually setting the current station, train number and other driving parameters, perform manual driving benchmarking operations at the specified driving benchmarking location to determine the train's departure locati...
