Embodiment 1

[0059] figure 1 Shown is the flow chart of the driving method of the fully automatic driving train provided by this embodiment. The method includes:

[0060] Step S1: When a fault occurs in a fully automatic train running normally, determine the level of the fault;

[0061] Step S2: When the level of the fault is lower than the preset dangerous level, control the train to travel to the next stop in the preset mode and stop.

[0062] It should be noted that: in step S1, if a failure is detected in a fully automatic train running normally, the level of the failure is judged. If the level of the fault is very low and does not affect the normal running of the vehicle, for example, the detected fault is the fault of the lighting system in some areas of the train, then it will still run in the normal mode.

[0063] If it is detected that the failure of the train has affected the communication between the train and the control center, or the number of abnormalities in the train is...

Embodiment 2

[0070] On the basis of Embodiment 1, step S2 also includes:

[0071] When the level of the fault is lower than the preset risk level, control the train to stop, send a request to the control center to enter the preset mode, and control the train to enter the preset mode after receiving the permission instruction.

[0072] It should be noted that in this embodiment, when the detected fault level of the train is lower than the preset dangerous level, the train is stopped. The control center is the integrated driving automation system TIAS. After the train stops, send a request command to TIAS to request to enter the preset mode. TIAS judges whether the train can enter the preset mode according to the fault type of the train and the surrounding environment information of the train. If the train can enter the preset mode, an instruction to allow entering the preset mode is sent to the on-board controller VOBC.

[0073] After the train receives the instruction allowing to enter ...

Embodiment 3

[0076] On the basis of embodiment 2, step S2 also includes:

[0077] When the train is running in the preset mode, it is judged whether there is a fault whose level is higher than the preset risk level, and if there is, the train is controlled to stop, and a manual maintenance request is sent to the control center.

[0078] It should be noted that if a train running in the preset mode detects a higher-level fault, it must stop and wait for maintenance. This is because if the train has a fault with a level higher than the preset risk level and continues to move, there may be potential safety hazards.

[0079] In the driving method of the fully automatic driving train provided in this embodiment, when the faulty train travels to the adjacent station at a low speed, if a fault with a higher risk level occurs, emergency braking will be performed to ensure the safety of the train .

Abstract

The invention provides a driving method and system of a full-automatic driving train. The method includes the steps that firstly, when a fault occurs in the normally-traveling full-automatic driving train, the level of the fault is judged; and secondly, when the level of the fault is lower than a preset danger level, the train is controlled in the preset mode to travel to a next station and stop, wherein in the preset mode, the traveling speed of the train is smaller than the preset speed. By the adoption of the driving method of the full-automatic driving train, when the low-level fault occurs in the train travelling in a full-automatic driving manner, the train can travel to the adjacent station at a low speed so as to be maintained, the train with the fault is prevented from affecting normally-travelling trains in the whole line, and convenience is provided for maintenance work of station maintenance personnel. Meanwhile, in the process when the train with the fault travels to the adjacent station at the low speed, if a fault of the higher level occurs, the train is urgently braked, and the safety of the train is guaranteed through the method.

Description

technical field [0001] The invention relates to the field of signal control, in particular to a driving method and system for a fully automatic driving train. Background technique [0002] With the rapid development of urban rail transit, higher requirements are put forward for the safety and automation of the entire train control system while operating efficiently. Compared with the manual driving system and the subsequent semi-automatic driving system, the fully automatic driving system effectively reduces the adverse effects caused by human errors, improves operational efficiency, and reduces operating costs. It is the development trend of urban rail transit control systems. [0003] In the fully automatic driving system, since there is no driver's participation, the control system monitors the corresponding parameters of the system itself and the train more strictly and in real time during the entire running process of the train, and detects existing or potential failure...
