Problems solved by technology

However, when the VOBC fails, the restart command of the trackside ATS is required to restart the VOBC. The implementation of this technology is highly dependent on the reliability of the wireless communication between the trackside and the vehicle. In addition, in this technology, for the board itself, The effective working time is not considered, which causes the board to fail due to long-term operation; finally, in this technology, there is no management of the running status of the board or software, so it cannot prevent the gradual progress, and can only be restarted after the failure

Embodiment Construction

[0048] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0049] Such as Figure 6 As shown, a method for restarting a train controller of the present invention comprises the following steps:

[0050] Step A: train VOBC calculates the conditions for timing restart;

[0051] Step B: Train VOBC summarizes fault information;

[0052] Step C: Train VOBC performs restart, including:

[0053] Step C.1: The train VOBC restarts at regular intervals;

[0054] Step C.2: Train VOBC remote restart;

[0055] Step C.3: Tr...

Abstract

The invention relates to a restarting method of a train controller. The method comprises the following steps that A, a train VOBC calculates timing restarting conditions; B, the VOBC of the train summarizes fault information; C, the VOBC of the train is restarted; and D, the two ends of the train are synchronized to realize main and standby redundancy. Compared with the prior art, the method has the advantages that multiple restart modes are provided, and the requirements under different conditions can be met, so that the influence of train controller faults on subway operation is reduced, andthe operation handling efficiency is improved.

Description

technical field [0001] The invention relates to the field of signal systems of rail transit, in particular to a method for restarting a train controller (VOBC, VitalOn Board Controller). Background technique [0002] At present, the driverless signal system based on GoA4 level has gradually become the mainstream and has been applied to many urban rail transit lines. The train controller is the core controller for train safety monitoring and operation management. In the unmanned driving project, for the subway trains operating online, if the train controller fails and cannot continue normal operation, it is necessary for the staff of the subway line to pedal to the scene of the faulty train to deal with it, which will lead to a longer processing time for the fault , has a greater impact on operations. [0003] After retrieval, Chinese Patent Publication No. CN109987118A discloses an abnormality handling method, device and system of a vehicle-mounted equipment control system...
