Activating and sleeping control circuit of urban rail train

Abstract

The invention discloses an activating and sleeping control circuit of an urban rail train. The activating and sleeping control circuit comprises local activating relays in all passenger coaches, activating control train lines, and activating control branch circuits in all driver cabs, wherein each activating control branch circuit comprises a self-reset activating press button and a train activating relay; one end of each self-reset activating press button is connected with a positive electrode of a power source, and the other end of each self-reset activating press button is connected with the corresponding activating control train line; each train activating relay corresponds to a first normally open contact, one end of each first normally open contact is connected with the positive electrode of the power source, and the other end of each first normally open contact is connected with the corresponding activating control train line; one end of each local activating relay is connected with a negative electrode of the power source, and the other end of each local activating relay is connected into the corresponding activating control train line; the activating control train line of each driver cab is connected with a first train hook connector. The activating and sleeping control circuit has the advantages that the operation is simple and convenient, the workload of train reconnecting is reduced, the labor cost of the reconnecting is reduced, the reconnecting efficiency of the urban rail train is improved, and the safety risk is avoided.

Description

technical field [0001] The invention belongs to the field of urban rail vehicle control, in particular to an urban rail train activation and dormancy control circuit. Background technique [0002] The existing urban rail train activation and dormancy control circuit has the following disadvantages: [0003] First, the train activation and train sleep in the driver's cab of the double-connected train share the same knob's opening and closing to realize. Before the trains are reconnected, the trains to be reconnected are independent vehicles, so the train activations are performed independently. After the trains are reconnected, because the original trains are powered on separately and cannot be controlled uniformly, it is necessary to perform train sleep operations on all reconnected trains separately. When the trains are reconnected and all trains are powered off, the train activation knob can be operated in any driver's cab of the reconnected trains to activate all reconn...

AI Technical Summary

Problems solved by technology

However, when the train is dormant, the power at the activation end of the train must be cut off to ensure that the power of the whole train is disconnected. Therefore, the dormancy of the train must be realized by turning the knob to the "point" position in the driver's cab at the end of the train activation knob, which is inconvenient to operate.
