Description

technical field [0001] The invention relates to a track parameter measuring device and method thereof, in particular to a railway locomotive track parameter measuring device and method based on an absolute coordinate measurement reference system. Background technique [0002] Due to the influence of the train movement, the railway track will gradually shift and settle, and the static curve parameters of the track will gradually change with time. When the change range of the track curve parameters exceeds a certain allowable value, it will affect the train running It may even cause serious accidents such as derailment and overturning of the train. In order to accurately control the parameters of the track curve, it is necessary to accurately measure the curve shape of the track and the spatial coordinate value of the curve in the geodetic coordinates. However, due to the limited technical level , in practical engineering applications, it can better measure the shape of the tr...
