Architecture for a data transmission between a plurality of electric traction vehicles and a corresponding remote control center

An architecture configured to transmit data between a plurality of electric traction vehicles moving in a transport network, which comprises a plurality of substations connecting with a low/medium voltage power supply network for the vehicles and a backbone ethernet network, the architecture comprising

• a transmission and decoupling system being inserted between the vehicles and substations connecting with the power supply network being used for a continuous data transmission according to the BPLC communication mode on the vehicles and the backbone ethernet network), the transmission and decoupling system comprising:
• an onboard device adapted to be placed onboard each vehicle and configured to connect to one of the grounded devices when the vehicles transit in correspondence of the grounded device;
• and
• a plurality of grounded devices, each grounded device adapted to be coupled to at least one of the substations,
• wherein
• each of the grounded devices comprises an adapter, which is directly connected to the ethernet backbone network and is a PLC master device;
• and
• the onboard device of each vehicle comprising an adapter being a PLC slave device.

A method for the continuous data transmission in an architecture configured to transmit data between a plurality of electric traction vehicles moving in a transport network, which comprises a plurality of substations connecting with a low/medium voltage power supply network for the vehicles and a backbone ethernet network, the architecture comprising:

• a transmission and decoupling system being inserted between the vehicles and substations connecting with the power supply network being used for a continuous data transmission according to the BPLC communication mode on the vehicles and the backbone ethernet network), the transmission and decoupling system comprising:
• an onboard device adapted to be placed onboard each vehicle and being configured to connect to one of the grounded devices when the vehicles transit in correspondence of the grounded device;
• and—a plurality of grounded devices, each grounded device being adapted to be coupled to at least one of the substations, each of the grounded devices comprises at least an adapter, which is directly connected to the ethernet backbone network and is a PLC master device;
• and the onboard device of each vehicle comprises an adapter being a PLC slave device,
• wherein the grounded devices are divided and alternating with respect to each other between a first type and a second type, each device type being adapted to be connected to a distinct module of the onboard device, the method comprising the steps of:
• transmitting a signal from each of the modules of the onboard device towards grounded devices of a same type;
• verifying a signal/noise ratio value of the transmitted signals as link quality parameter;
• selecting a signal with a maximum value of signal/noise ratio among the transmitted signals;
• and
• connecting one of the modules of the onboard device with one of the grounded devices which correspond to the signal with maximum value of signal/noise ratio,
• the above steps being repeated in following times while the vehicle is moving in order to guarantee the continuous data transmission.
