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 the rail transit train failure described in the embodiment of the present invention is as attached figure 1 shown. in the attached figure 1 Among them, the train control system includes a train network control system 1, an on-board signaling system 2, a driver console 3, a train driving control unit 4, a train braking control unit 5, a driver display 6 and a control center 7, which can be automatically controlled by the on-board signaling system 2. Control the car, or manually control the car through the driver console 3. Among them, K is the transfer switch between the fully automatic driving mode and the manual driving mode of the train.

[0056] as attached figure 2 to attach Figure 5 Shown, a kind of embodiment of the safety control system under the rail transit train failure, specifically comprises: several train drive control units 4, are used to output drive ...

Embodiment 2

[0065] Embodiment 1 provides the logical judgment of whether the driving / braking conditions are allowed by using the train relay logic combination circuit (ie, the driving logic combination circuit 8 and the braking logic combination circuit 9 ). In addition, in the fully automatic driving system (ATO), since the on-board signaling system 2 is used to control the car, the on-board signaling system 2 needs to obtain information on whether the emergency traction conditions are met. In this case, the on-board signal system 2 can be used to directly collect the working status of each traction drive / braking control unit, and the logic combination analysis can be carried out through software to determine whether the driving / braking conditions are allowed, so as to determine whether the on-board signal system 2 can be normal. Conditions to enter creep mode. In the fully automatic driving mode, the on-board signaling system 2 acts as the driver to control the train running, so it is n...

Embodiment 3

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

Abstract

The invention discloses a safety control system and method under rail transit train failure, comprising: a plurality of train drive control units and a plurality of first state indication units. The first contacts of the first state indicating unit form a driving logic combination judging branch connected in parallel, and each driving logic combination judging branch includes M first contacts connected in series. Among them, N is the number of drive control power units included in the train, and M is the minimum value of the available number of drive control power units that meet the requirements of train traction start. When any one of the driving logic combination judging branches is connected, the train driving condition is satisfied, and the emergency traction permission command is output to each driving control power unit through the driving logic combination judging branch. The present invention can solve the technical problem 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, switching to the emergency traction mode may cause the train to fail to start or even the risk of slipping.

Description

technical field [0001] The invention relates to the technical field of rail traffic control, in particular to an emergency traction control system and method for rail traffic trains when the train network control system fails or fails. Background technique [0002] In the normal operation of existing rail transit trains, there are usually two modes: the on-board signal system automatically controls the train operation or the driver manually controls the train operation, 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 creeping (full automatic driving). When the train network control system fails or fails, the control center needs to be remotely intervened by the control center (in the fully automatic driving mode) or the driver intervenes on the vehicle (in the driver'...
