Abstract

The invention provides a method for dynamical reconnection of trains and nodes. The method comprises the following steps that a target ETBN node receives node number information sent by a host machine; according to the number information, the target ETBN node sequentially obtains MAC address and subnet identification of each ETBN node in the first direction and MAC address and subnet identification of each ETBN node in the second direction; the target ETBN node sequences node numbers of each of the ETBN nodes in the first direction and each of the ETBN nodes in the second direction; and according to the sequence, the target ETBN node performs associative memorizing on the node number of each of the ETBN nodes and the corresponding MAC address into a physical topology list and performs associative memorizing on the number of each of the ETBN nodes and the corresponding subnet identification into a logical topology list, so that the reconnection of the trains is realized according to the physical topology list and the logical topology list, and automatic identification between marshalling of the trains and the reconnection of the trains in nonstationary marshalling are realized.

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...
