One kind of locomotive reconnection wireless data communication method and system

The present invention discloses a wireless data communication reconnection method and system for a locomotive. The vehicle system comprising at least a first master DTE-L, a first master vehicle OCE, the second master vehicle DTE-L, a second master vehicle OCE, controlled from the locomotive and the DTE-L slave locomotives OCE, and ground marshalling application server; first / second vehicle master DTE-L, for receiving the first / second master OCE vehicle frame and transmitting data traffic to a second data traffic frames transmitted / a master vehicle and the slave DTE-L locomotive DTE-L, and the frame transmitted from the second / a master vehicle DTE-L received from the control data traffic to the motorcycle DTE-L; grouping terrestrial application server for receiving the first / second vehicle master DTE-L transmission, and the vehicle license plate number transmitted from the master control locomotives DTE-L, and into a group, and transmits the address information to the group members of the first / second vehicle master DTE-L, and the slave locomotives DTE-L. The present invention can effectively overcome the air interface link loss, the wireless system device reconnection failure caused by traffic safety hazards.
