Accurate train location detection system using stagger information of the overhead contact lines

摘要

The present invention relates to a high-precision train position detection system using catenary deviations information, wherein laser light is irradiated from a train roof to a catenary, the reflected light is detected to measure the deviation value of the catenary, And the length of each span is calculated by dividing the total length of the meteorological supporter location information and the span length arrangement / configuration, or overlap period (the total length of the meteorological support 2 And the information on the location of the train in the real time. According to the present invention as described above, the position of the electric cable support does not change during the lifetime of the railway line, and the electric line support is maintained at a constant interval It is possible to provide an accurate train position detection system in which precision of less than 1 m is ensured because the information of the position of the support line of the electric cable carrier possessed by the railway operator has accurate data up to 1m unit.
