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.

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.

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 driving mode operation;

[0030] If the controller handle is in the brake position, the ATO level signal is ignored, and the final control level signal is the train control signal, output the brake command, and prompt on the driver display "ATO mode exits, please drive manually! ", At this time, the train exits the automatic driving mode;

[0031] 2) When ATO is in a non-traction condition:

[0032] If ATO is an emergency brake, then directly output emergency brake instructions, and prompt "emergency brake is applied!" And the train keeps the automatic driving mode;

[0033] otherwise:

[0034] If the probe is in the fast braking position, the quick brake instruction is output directly, exit the ATO mode, and prompts "manual driving, fast brakes!";

[0035] If the train is a common brake condition, if the probe handle is in the brake zone, and the ATO level

[0036] If the probe is in the traction, ignore the procurer signal, keep the ATO mode to travel, take the ATO level signal as the train control signal, at this time, if the ATO is the brake command, output the brake command, if the ATO is idling The instruction is output.

[0037] In the second embodiment of the present invention, the train control unit is configured or programmed to perform the steps of the first level 1 control method.

[0038]Specifically, the train control unit can include the following module:

[0039] The determination module is used to determine whether the auto-driving mode signal is detected. If it is, then it ends; if so, the execution module performs the following first execution unit and the second execution unit:

[0040] In the first execution unit, if the train is in the traction conditions, the train control signal is output according to the mounted handle action signal;

[0041] The second execution unit, if the train is in a non-dispatched condition, the emergency brake command is output when the automatic driving mode is emergency brake; otherwise the train control signal is output according to the mounted handle action signal.

[0042] Specifically, the first execution unit, the second execution unit outputs the process of the related instruction, which is the same as the output of the corresponding instructions in the first embodiment, and details are not described later.

[0043] The train control unit in the second embodiment of the present invention does not change the structure of the original train control unit, but the associated control program is contained in the original train control unit to facilitate the implementation of the train level bit control.

[0044] Embodiment 3 of the present invention provides a rail transit vehicle that employs a train control unit provided in Example 2. The train control unit is connected to the driver's room display, and the computer is electrically connected. The train control unit can acquire the motion signal of the procuretor handle and combine the automatic driving mode signal, the train working condition signal determines the train control signal, and transmits the relevant control command to the driver room display.
