Problems solved by technology

[0007] In view of this, the object of the present invention is to provide a safety control system and method under rail transit train failure, to solve the situation that the existing emergency traction mode is not combined with the available capacity of the traction system itself. In the case of complete or partial traction failure, Once switched to emergency traction mode, there may be technical problems that may cause the train to fail to start or even slide down the slope

Embodiment 1

[0055] The structural block diagram of the train control system applied to the safety control system under rail transit train failure described in the embodiment of the present invention is as attached figure 1 Shown. Attached figure 1 The train control system includes the train network control system 1, the on-board signal system 2, the driver console 3, the train drive control unit 4, the train brake control unit 5, the driver display 6 and the control center 7. Control the car, or manually control the car through the driver console 3. Among them, K is the switch between the train in fully automatic driving mode and manual driving mode.

[0056] As attached figure 2 Attached Figure 5 As shown, an embodiment of a safety control system under rail transit train failures specifically includes: a number of train drive control units 4 for outputting drive control signals to corresponding drive control power units 10; and set in the train drive control The output terminal of the un...

Embodiment 2

[0065] Embodiment 1 provides the use of train relay logic combination circuit (ie, drive logic combination circuit 8 and brake logic combination circuit 9) to realize the logic judgment of whether driving / braking conditions are allowed. In addition, in the fully automatic driving system (ATO), since the on-board signal system 2 is used to control the car, the on-board signal system 2 needs to obtain information on whether the emergency traction conditions are met. In this case, the working status of each traction drive / brake control unit can be directly collected through the on-board signal system 2, and the logic combination analysis can be performed through software to determine whether the driving / brake conditions are allowed, and this can be used as the on-board signal system 2 to determine whether it is normal Conditions for entering creep mode. In the fully automatic driving mode, the on-board signal system 2 acts as a driver to control the operation of the rail transit t...

Embodiment 3

[0070] Embodiment 1 provides the use of train relay logic combination circuit (ie, drive logic combination circuit 8 and brake logic combination circuit 9) to realize the logic judgment of whether driving / braking conditions are allowed. In addition, the logic control unit 13 (LCU, Logic Control Unit) can also directly collect the working status of each traction drive / brake control unit, and analyze the logic combination through software to determine whether the drive / brake condition is allowed, as a judgment Whether it is possible to enter the emergency traction permission mode normally. In Embodiment 1, the closing / opening of the auxiliary contact through the relay indicates normality / abnormality of the corresponding train drive / brake control unit. If the emergency traction control of the train is implemented by the logic control unit 13, software logic is used to determine whether the emergency traction condition is allowed.

Abstract

The invention discloses a safety control system and method under a rail transit train fault. The safety control system comprises a plurality of train driving control units and a plurality of first state indication units. First contacts of the first state indication units form driving logic combination judgment branches which are connected in parallel, and each driving logic combination judgment branch comprises M first contacts which are connected in series. N is the number of driving control power units included in a train, and the M is a minimum value of the available number of the driving control power units meeting a traction starting requirement of the train. And when any one driving logic combination judgment branch is connected, the train driving condition is met, and an emergency traction permission instruction is output to each driving control power unit through each driving logic combination judgment branch. A technical problem that an existing emergency traction mode is notcombined with an available capacity of a traction system, and under a condition that traction is complete or partially invalid, the emergency traction mode is switched to so that the train cannot be started, and even a slope sliding risk is caused can be solved.

Description

Technical field [0001] The invention relates to the technical field of rail transit control, in particular to an emergency traction control system and method for rail transit trains when the train network control system fails or fails. Background technique [0002] Under normal operation of existing rail transit trains, there are usually two modes of automatic control of train operation by the on-board signal system or manual control of train operation by the driver, both of which need to be controlled by the train network control system. However, when the train network control system fails or fails, the train will stop, and the driver or the control center will downgrade the train operation mode to emergency traction or creep (fully automatic driving). When the train network control system fails or fails, the control center needs to remotely (in fully automatic driving mode) or the driver intervenes on the car (in the driver's manual driving mode), and the train enters emergency...
