| Abstract: | With an introduction of the leakage coaxial cables and based on the multisensory information fusion,the present situation of train positioning is discussed.The implementation of CBTC mode for train precise positioning with this new technology is theoretically analyzed,in order to solve the defects caused by the existing adopt track circuit and beacons conduct,such as the low train positioning precision and long initialization process.Finally various standard train positioning systems are compared for the future direction of train positioning technology. |
