In order to solve the problem of wireless loading of line data for heavy-haul railways and normal-speed railways and minimize the dependence on the coverage of wireless network,it is proposed that under the condition of wireless network coverage only at stations,the line data within the train path can be searched in real time according to the train running direction,train location,section length,turnout position and section locking direction,and accurately sent to the train in point-to-point mode.Under the condition that the section is not covered by wireless network,the prefabricated line data of the section is sent to the train in advance at the station in point-to-point fixed period.The on-board equipment judges the location of the estimated front end of the train,adopts the station line data or the section line data,and calculates the distance-to-go continuous speed curve according to the track circuit code to monitor the safe operation of the train.The proposed method effectively reduces the requirements of wireless communication range for line data loading,and reduces the implementation difficulty and investment cost of line transformation.
