摘要： The present invention relates to an early warning protection system based on Beidou position automatic sensing, the system is in communication connection with a TDCS/CTC system, and the early warning protection system includes a locomotive train-mounted terminal subsystem, a ground early warning protection platform subsystem, and a handheld terminal subsystem, the ground early warning protection platform subsystem is in communication connection to the TDCS/CTC system, the locomotive train-mounted terminal subsystem, and the handheld terminal subsystem respectively; and the ground early warning protection platform subsystem performs judgment processing on train-to-train and train-to-person early warning logics according to Beidou positioning, a train speed, and train direction information provided by the locomotive train-mounted terminal subsystem and Beidou positioning information of the handheld terminal subsystem and with reference to station information and train number information sent by the TDCS/CTC system and line data and data of a virtual transponder, and forwards processed early warning information to the locomotive train-mounted terminal subsystem and the handheld terminal subsystem. Compared with the prior art, the present invention has the advantages of implementing early warning and protection for railway construction personnel, a train, and the like.
