Abstract

The invention discloses a train positioning method and device. The method comprises steps of obtaining the differential position information of a train from a satellite receiver, and obtaining the driving information of the train from an inertial navigation unit; and carrying out positioning calculation according to the differential position information and the driving information so as to outputthe positioning information of the train. According to the method, positioning precision is improved, the error is reduced, implementation and deployment are convenient, and construction cost is low.

Description

technical field [0001] The invention relates to the technical field of rail transit train positioning, in particular to a real-time high-precision positioning method and device for smart rail cars. Background technique [0002] Train location information plays an important role in automatic train control technology. The realization of almost every sub-function requires the train location information as one of the parameters. Therefore, train location is a very important link in the train control system. Accurate location information is also a prerequisite for safe and efficient train operation. [0003] The smart rail car is a new type of two-way multi-group rubber-tyred vehicle. It is based on the traditional rail transit system design concept, adopts all-axis steering control technology, and electronically constrains driving through active safety control, on-board signal control, machine vision, etc., to realize similar track driving under virtual tracks. Among them, sub...
