Problems solved by technology

When the vehicle control unit is in ATO mode, if it detects the level signal of the controller handle (the level signal of the controller handle includes the traction position signal, the fast braking position signal and the braking position (that is, the normal braking position) signal) change, the level signal of the controller will be used to control the operation of the train. Since the source of the level signal changes, the size of the level signal will change. Under braking conditions, if the level signal of the controller is greater than If the level signal of the signal system is used, the train will stop in advance (substandard). If the level signal of the controller is lower than the level signal of the signal system, the train will stop later (marked). Under normal circumstances, when the line is abnormal , the driver takes over the control of the train in order to stop the train in advance, but under the existing judgment method, because the driver accidentally touches the controller or the driver operates the controller in advance before the train stops, the train will not be able to follow the signal system.

Example Embodiment

[0025] Embodiment 1 of the present invention rationally controls the train level according to different operating conditions, different level signal sources (ATO or miver) in accordance with the ATO mode, and ensure that the train is safely operational Squire problem.

[0026] The first embodiment of the present invention control method is as figure 1 Indicated.

[0027] In ATO mode, the train control unit (VCU) decelerates according to the traction instruction, brake command, level signal instruction, etc. from the signal system, and the driver will take the control of the train when the train is urgent. The VCU detects the operator action and judges the operating instruction output at the time of the signal system:

[0028] 1) When the ATO is in the traction condition:

[0029] If the probe handle is in the traction, the procurer signal is ignored, and the ATO level signal is taken as the train control signal, output traction instructions, and the train keeps the automatic drivi...

Abstract

The invention discloses a train level control method, a train control unit and a rail transit vehicle, and the method comprises the steps: judging whether an automatic driving mode signal is detected or not, and if not, ending; and if yes, carrying out following steps. According to the method, it is guaranteed that a driver can decelerate or stop the train in advance under the emergency condition, the problem that the train rushes out of the standard due to mis-operation of the driver or other factors can be effectively solved, the running safety is greatly improved, and the operation efficiency of the train is improved.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a train level control method, a train control unit and a rail transit vehicle. Background technique [0002] When the subway train is running normally, it mainly adopts the automatic driving (ATO) mode. In this mode, the traction, braking, grade signal, door opening and closing, station announcement, etc. of the train are all controlled by the signal system, and the driver does not need to participate. When an emergency occurs on the train in the automatic driving mode, such as pedestrians or other obstacles appearing on the track, or there is a special situation on the train itself, the driver needs to take over the control of the train. At this time, the driver can operate the controller handle to control The train stops early or slows down. When the vehicle control unit is in ATO mode, if it detects the level signal of the controller handle (the level signal of the contr...
