Abstract

A method for dynamic reconnection of trains comprises: a target ETBN node receives node number information sent by a host computer (101); the target ETBN node obtains the MAC address and the subnet identifier of each ETBM node in the first and the second directions in turn according to the number information (102); the target ETBN node sequences the node number of each ETBN node in the first and the second directions in numerical order (103); the target ETBN node associatively stores the number of each ETBN node and the corresponding subnet identifier in a logical topology list according to the sequence, in order to realize the reconnection of trains according to the physical topology list and the logical topology list (104), thereby realizing the automatic identification among the marshalling of trains, and the reconnection of trains among ambulatory marshalling. A node for dynamic reconnection of trains is also provided.

Description

technical field [0001] The invention relates to the technical field of train reconnection, in particular to a method and node for dynamic reconnection of trains. Background technique [0002] The train has the characteristics of dynamic formation, that is, the number of train formations can be changed according to the needs, and the reorganized train formations can recognize each other and carry out normal inter-network communication. [0003] In the prior art, the formations of the train realize communication through the train Ethernet, and the train Ethernet is an industrial Ethernet used for control information transmission on the train. Compared with ordinary civil Ethernet and industrial Ethernet, train Ethernet needs to dynamically reorganize the network. After reorganization, different vehicles can recognize each other and establish a train marshalling index, that is, each vehicle can know how many other vehicles join the marshalling. [0004] However, the current tr...
