DG-DN8255 - Duro-Net Railway Power-Line Modem

• 

The Duro-Net DG-DN8255 is a pupose built railway Power-Line Modem which can be used with 24/110VDC or 240VAC power lines. Included is a embedded self adaption filter and communication controller, which ensure the best performance under different electrical environments and different media. The DG-DN8255 is ideal for modernisation and upgrade projects, where no additional cabling is available for creating a train-wide TCP/IP Ethenet network. One Power-Line modem is configured as the master device, which support several hundreds of slave devices on the same network.

Every SLAVE is paired with the MASTER device, which is typically located in the Driver Cab attached to the HMI. A SLAVE node can communicate with the MASTER node and any other SLAVE node, which has been paired with the same MASTER device on the train. Typically SLAVE nodes are conected to the Coach-Controller of the PI-System. With a train-wide Ethenet network, announcement audio files and messages can be updated easily from a single point from the main PIS HMI in the Driver Cab.

The modem is based on wavelet OFDM (Orthogonal frequency division multiplexing) technology. It has unique advantages, which include:

• Efficient use of the available bandwidth
• Sharp side band rejection since signals is orthogonal in both frequency and time domains
• Wavelet OFDM is the only technology, which can pass EMC regulations
• Strong noise rejection capability
• Silicon-level AES 128 encryption
• Transparent 10/100Mbit Ethernet interface with zero configuration

The DG-DN8255 is available in three variants:

• DG-DN8255-01 for 24/48VDC powered systems such as Diesel locomotive trains or trams
• DG-DN8255-02 for 74/110VDC powered train systems
• DG-DN8255-03 for 240VAC line powered systems

DG-DCORE-DR01-R - 5G Railway Router

The DCORE-DR01-R is a powerful stand-alone high reliability 5G Train EDGE Gateway Router with a dedicated LINUX application processor capable of independently executing Client Services. This device combines the functions of an EDGE gateway computer with a HW accelerated dedicated WRT router core, which directly manages the 5G modem. Separate processors are used for application software and the WRT Linux router to improve performance and enable easier software development. The application processor directly connects to the core router with an internal Ethernet interface. This enables independent upgrading of application layer software services without the need to touch the Layer 3 routing core software.

The small footprint DCORE-DR01-R is ideal for upgrade programs due to its small size and support for project specific firmware adaptations. Train location is based on an IMU supported high sensitivity ADR GNSS subsystem. The 5G modem is based on the latest Qualcomm SDX65 chipset, which supports UL and DL MIMO using n40 and n78 bands. Standard M12 connectors are used for the Ethernet interfaces.

The router features a soldered down GNSS subsystem with UDR support for installation cases where limited satellite coverage is available. The UDR based positioning can reliably navigate underground or in poor satellite signal conditions assisted by the IMU based sensor data.

Duragon can supply a suitable railway compliant antenna with 2x2 MIMO 5G and GNSS.

The small footprint DURION-DR01 is ideal for upgrade programs due to its small size and support for project specific firmware adaptations. Train/Bus location is based on an IMU assisted high sensitivity UDR/ADR GNSS subsystem. The 5G modem is based on the latest Qualcomm SDX65 chipset, which supports 2x2 UL and DL MIMO using n40 and n78 bands. Standard RJ45 connectors are used for the Ethernet interfaces. An optional high transmit power 802.11ax/ac WiFi is available for the DURION-DR01, please consult Duragon for more details.

The router features a soldered down GNSS subsystem with UDR/ADR support for installation cases where limited satellite coverage is available. In ADR mode the vehicle speed and direction is extracted from the vehicles. The ADR/UDR based positioning can reliably navigate underground or in poor satellite signal conditions assisted by the IMU based sensor data.

A suitable rooftop railway compliant antenna is availanble with 2x2 MIMO 5G and GNSS, 5m cables and FAKRA connectors.
