Abstract

The invention discloses a radar-based train positioning method and device. The train positioning method comprises the following steps: pre-constructing a radar scattering feature map; acquiring a current local environment map based on the current echo data of the radar; and matching and comparing the current local environment map with the radar scattering characteristic map to calculate the current position of the train. According to the method, the real-time positioning precision of the train is improved, and positioning auxiliary equipment beside the track is effectively reduced, so that theconstruction cost and the maintenance cost of train positioning are effectively reduced, the real-time detection of the road condition environment is realized, and the safety and the reliability of train operation are further improved.

Description

technical field [0001] The present invention relates to the technical field of vehicle positioning, in particular to a radar-based train positioning method and device. Background technique [0002] Train position information plays an important role in train automatic control technology. The realization of almost every sub-function requires train position information as one of the parameters. Therefore, train positioning is a very important link in the train control system. Accurate location information is also a prerequisite for the safe and efficient operation of trains. [0003] At present, the train is mainly positioned by the method of "initial position + speed and time integration + transponder calibration". Although the positioning method of "initial position + speed and time integration + transponder calibration" can overcome the influence of environmental factors such as tunnels and mountain streams, the speed and time integration error increases with the increase o...
