WTB node initial operation method and system for preventing node address abnormity

Abstract

The invention provides a WTB node initial operation method and system for preventing node address abnormity, and the method comprises the steps: completing the initialization and naming operation of a node in a WTB, and after a slave node receives a topology request message from a main node in a topology release process, sending the topology request message to the main node; controlling the slave node to verify the logic of the current topology based on the number of the nodes in the message, further verifying the correctness of the topology logic according to the node address in the previously received naming request message and the node address in the current topology request message when the verification is passed, and after the verification is passed, sending the verification result to the slave node; and returning a topology response message to the main node to complete the initial operation. By adopting the scheme of the invention, the correctness of the initial operation logic of the WTB is ensured by utilizing various detection mechanisms, the defects of high abnormal probability and dependence on manual assistance in the existing initial operation technology can be overcome, meanwhile, automatic recovery can be realized when the initial operation of the WTB is abnormal, and the reliability of the WTB is improved on the premise of meeting the high reliability requirement. And the high automation and the execution efficiency of the initial running process of the WTB are improved.

Description

technical field [0001] The invention relates to the technical field of WTB bus management and optimization, in particular to a WTB node initial operation method and system for preventing abnormal node addresses. Background technique [0002] WTB, the train control backbone network of twisted-wire bus, is widely used in the field of rail transit. For example, standard EMUs, Harmony D1 trains, intercity EMUs and other trains in use all use WTB technology as the train reconnection technology. Traditional management In the method, the standard WTB initial operation method is used to detect the WTB topology, and various timers are used to realize periodic process control. However, due to the differences in the hardware of each terminal device, the clocks of each terminal device cannot be completely synchronized. , leading to some abnormal situations inevitably appear in the initial operation process, especially for the train system with increasing system complexity, the probabili...
